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.
