The elastic sleeve pin coupling has a relatively simple structure, easy to manufacture, does not require lubrication, does not need to be bonded with metal vulcanization, it is convenient to replace the elastic sleeve, does not need to move the half coupling, and has a certain degree of compensation for the relative deviation of the two shafts and damping and buffering performance.. The work of the elastic sleeve is compressed and deformed. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, the elastic sleeve pin coupling can compensate the axis displacement and elasticity, but the allowable compensation amount for the axis displacement is less. The elasticity is weak. The elastic sleeve pin coupling relies on the locking force of the pin group to generate the frictional moment on the contact surface, and compress the rubber elastic sleeve to transmit the torque. It is suitable for small and medium-power shafting transmiss ions with good rigidity of the installation base, high centering accuracy, low impact load, and low vibration reduction requirements.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!

Diaphragm coupling is by several groups of diaphragm (stainless steel thin plate) using bolt crisscross with half coupling, diaphragm composed of several pieces fold sets in each group, the diaphragm can be divided into connecting rod type and different shapes of the chip.
The elastic sleeve pin coupler is a pin with a flexible sleeve (rubber material) on one end, which is installed in the flange hole of the two-part coupler to realize the coupling of the two-and-a-half coupling. Column elastic sleeve pin coupling was once a coupling device of the most widely used in our country, as early as the late 1950 s, which is for the mechanical standards, JB08-60 elastic dowel pin coupling, is China's first standard coupling.

Harsh environmental conditions present difficult challenges in terms of the design of all the equipment. Electrical connectors must work reliably and uninterruptedly in everyday use in order to guarantee perfect operation. Stäubli connectors for harsh environments meet these requirements. The established Stäubli MULTILAM technology guarantees for maximum dependability at low resistances and therefore extremely low energy loss and low insertion force despite multiple electrical contacts.Get more news about Harsh Environment Connector,you can vist our website!
RAILWAY APPLICATIONS
Electrical connectors used in the railway industry are subject to extremely harsh environmental conditions on a daily basis. Strong temperature fluctuations (e.g. snow and ice in alpine areas), high mechanical strain, vibration, and contamination cannot be allowed to impact the reliability of power, signal and data transfer. Stäubli has developed a sturdy casing, the handle that can even withstand blows from a hammer when opening. Stäubli MULTILAM contact technology ensures a continuous electrical connection, even in the event of strong vibration or temperature fluctuations. The 15° outlet angle of the plug reduces mechanical strain on the cable and simplifies actuating the connection.
MINING APPLICATIONS
Stäubli provides reliable solutions that can withstand specific environmental conditions above and below ground, including dust and shock impacts, and thus guarantee uninterrupted operation. We pride ourselves in customer-specific applications tailored to your technical needs. Because of that, our contact technology can be used, not only in removing machines (e.g. diggers, drilling machines), but also in transport and further-processing systems (e.g. griding machines, sorting, washing systems).
MARINE APPLICATIONS
In ports and on ships, connectors are exposed to sea water, and the salt content of the air is higher than in most other areas. Long-term use in this kind of environment requires not only waterproof characteristics but also a particularly sturdy casing. Stäubli connectors for harsh environments meet these requirements and can be fitted with different contacts based on customer requirements. The connectors can meet a range of different requirements in the port and the offshore sector.
Electronic connector experts Omnetics sets itself apart from more traditional suppliers by collaborating closely with customers, and by getting to know their specific needs and challenges to build bespoke solutions that really work.Get more news about Harsh Environment Connector,you can vist our website!
The company's collaborative approach is perhaps most effective when working to create "harsh environment" connector solutions. These are often bespoke solutions, built for customers in key sectors like aerospace, defence, energy and medical, which, due to their application, must be enhanced with special features to ensure they continue to work effectively in extreme, or "harsh", environments.
Harsh environment connectors may be required to work at very high temperatures, for instance, or be able to withstand repeated shock and vibration. Some harsh environment connectors must work well at high speeds, or altitudes, like those within aerospace or space sector applications. Others, meanwhile, need to be especially resistant to dirt or moisture ingress, like those in military or oil & gas sector applications.
Travis Neumann, Special Projects Manager at Omnetics, considers harsh environment connectors to be any needing enhanced features that don't fall within normal military (MIL) standards for connectors. "Our connectors are made to standards MIL-DTL-83513 for Micro D's, and MIL-DTL-32139 for Nano D's," he says.
"When we talk about harsh environment connectors, for me that means solutions that have requirements above and beyond those industry standards. It might mean the customer needs connectors with a wider temperature range than -40 to 125°C, for example, or they may need additional sealing requirements to increase resistance to dust and moisture ingress.
"If the connectors are going to be on board a ship, and need to work at or near the sea, for instance, the customer could need additional corrosion resistance. Or, if the customer is an aircraft operator, they may have greater EMI-shielding requirements. These are all common customer needs when it comes to harsh environments."
Establishing exactly what the customer needs from their solution can be the hardest part of the process of designing, manufacturing, and then delivering a successful harsh environment product. Omnetics works on a case-by-case basis, taking the time to truly understand a customer's challenges and emphasising the value of clear and open communication.
"It all depends on the customer," says Scott Fitzharris, Design Engineer at the company. "Some already know everything they want from their product, and arrive ready with a checklist for us to work through. Others can't tell you a lot about their needs but can at least say where the product will be applied, and how it needs to perform.
"Then, some customers know they need something but don't specifically know what that solution is. That's when you really do have to collaborate. If the customer can't provide enough information, we'll work with them to find a solution. We may build them a sample, for example, just to try it out. Our customer can review the aspects and provide feedback to those which did or didn't perform well. Then, we can change the specifications until we get the right results.
To emphasise the complexities of building bespoke connector solutions for certain harsh environments, Fitzharris provides an example of working with a company in the aerospace sector. "The customer came to us and just said they needed EMI (electromagnetic interference) shielding, and that's it," he says.
According to the size of the load transmitted by the gearbox, the level of the shaft speed, the installation accuracy of the two parts to be connected, etc., referring to the characteristics of various shaft couplings, choose a suitable shaft coupling type. The following suggestions can be considered when choosing specifically:Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!
1) The size and nature of the torque to be transmitted and the requirements for the cushioning and vibration reduction functions. E.g, for high power heavy-duty gear reducers, gear shaft couplings can be used; For severe impact loads or gear reducers that require the elimination of torsional vibrations of the shaft shafting, tire-type couplings, and other highly flexible couplings can be used.
2) The working speed of the coupling and the magnitude of the centrifugal force caused.
For high-speed transmission shafts, couplings with high balance accuracy should be used, such as diaphragm couplings, etc., and slider couplings with eccentricity should not be used.
3) The magnitude and direction of the relative displacement of the two axes.
After installation and adjustment, it is difficult to maintain strict and accurate alignment of the two shafts, or when the two shafts will produce a large additional relative displacement during work, a flexible coupling should be used. For example, when the radial displacement is large, the slider coupling can be selected, and if the angular displacement is large or the two shafts intersect, a universal coupling can be used.
4) Reliability and working environment of the coupling.
Couplings that are usually made of metal components and do not require lubrication are more reliable; couplings that require lubrication are susceptible to the performance of the lubrication and may pollute the environment. Couplings containing non-metallic components such as rubber are sensitive to temperature, corrosive media, and strong light, and are prone to aging.
5) Manufacturing, installation, maintenance, and cost of the coupling.
Under the premise of satisfying convenience performance, the coupling should be selected for easy assembly and disassembly, simple maintenance, and low cost. For example, the rigid coupling is not only simple in structure, but also easy to assemble and disassemble. It can be used for low-speed, high-rigidity transmission shafts. General non-metallic elastic element couplings (such as elastic sleeve pin couplings, elastic pin couplings, plum-shaped elastic couplings, etc.), because of their good comprehensive capabilities, are widely used in general medium and small power transmission.
Shear type or sleeve type couplings originated in the 1950s. It is a very popular choice for pump applications where it gained early acceptance and has grown organically across many industries including wastewater, paper/pulp, marine and steel to name a few.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!
The shear type coupling is a very simple design and is comprised of 2 flanges and 1 sleeve. The torque is transmitted through the twisting of the elastomeric sleeve and virtually eliminates the load on bearings and shafts and is excellent with vibration dampening. As with other elastomeric couplings, it is a low maintenance and non-lubricated coupling option.
Lovejoy, Inc. set a goal to redesign the sleeve coupling product and to make it the highest quality and longest lasting offering available at the same competitive price. The result is the S-Flex EnduranceTM, a new and improved, longer lasting EPDM rubber sleeve material.
The new S-Flex Endurance coupling design has undergone extensive dynamic cycling testing. The results of this testing prove the S-Flex Endurance EPDM material provides higher performance and enhanced durability than its previous iteration.
Testing was performed to determine the actual physical performance and torsional capabilities of the new EPDM sleeves. The test articles were installed between the torque actuator's driving S-Flex flange and a driven torque transducer flange. The testing regiment consisted of accelerated fatigue testing where the sleeves were subjected to high frequency start-stop-reverse cyclic loading. The sleeves completed extensive testing at loads greater than the sleeve's torsional ratings. The sleeve's performance characteristics were collected for comparison to the original material and the competitor's product. The static torsional stiffness was repeatedly measured as the slope of a stress-strain curve during dynamic cycling testing. The dynamic torsional stiffness was also continuously evaluated over the full test duration. As an additional performance guide, the competition's equivalent sleeve materials were evaluated as well.
S-Flex Endurance sleeve's static and dynamic torsional stiffness tested at least 30% greater than the former Lovejoy material and outperformed the current products in the market. The S-Flex product operated with more resilience and consequently less heat build-up. Furthermore, post-test inspections showed the new sleeves are very durable under these extreme test conditions, as they maintained their tooth shape and displayed minimal wear.
The Sleeve Life
Test Duration Graph shows that the former EPDM sleeves lasted an average of 747k cycles before reaching torque overload failure where the sleeves failed and could no longer transmit the set torque. The new EPDM material was tested for a week up to about 4.75 million cycles and no signs of failure were present at which point testing was ended. Accelerated fatigue testing is performed at severe high-torque and high-frequency conditions. Typical operation cycle life will greatly exceed the test cycles in the graph. The cyclic fatigue test conditions demonstrate the new EPDM material has at least a 3X longer life expectancy, if not more, than the former material.
ZLL elastic pin coupling is a kind of pin made of some non-metallic elastic materials, which is placed in the flange holes of the two-half coupling and connected with the two-half coupling through the pin. The structure of the coupling is simple and easy to manufacture. It is convenient to install, disassemble and replace the elastic elements without moving the two coupling. The material of elastic element (pin) is usually nylon 6, which has the ability of micro-compensation for the offset of two axes. The elastic element is sheared when it works, and its reliability is very poor. It is only suitable for medium-speed transmission shafting with very low requirement, but not for high requirement of reliability.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!
