Actual selectionUniversal couplingWhen considering the following aspects: mostUniversal couplingAll have been standardized or standardized.The designer’s daily task is to adopt, not design solutions.The basic process of using couplings is as follows: select the type of coupling according to the size of the transmitted load, the height of the shaft speed ratio, the installation precision of the two components to be connected, etc., refer to the characteristics of various couplings, and select a common coupling Coupling type.

1) The required transmission torque size and characteristics and its provisions on buffer shock absorption.For example, gear couplings can be used for high-power light-load transmission systems; for transmission systems that require severe impact loads or require removal of shaft distortion and vibration, crawler-type couplings and other high-elastic couplings can be used. Shaft.

2) The size of the centripetal force caused by the ratio of the rotation speed in the work of the coupling.For high-speed rotating shafts, balanced and high-precision couplings, such as pulse damper couplings, should be used instead of slider couplings with axial force.

3) The size and orientation of the relative displacement of the two axes.When the strict and precise alignment of the two shafts cannot be maintained after installation and adjustment, or the two shafts will cause a large extra relative displacement during the whole process of work, a flexible coupling should be used.For example, when the axial deviation is large, the slider coupling can be selected, the angular velocity is large or the connection of the cross two shafts can be usedUniversal couplingand so on.

4) The credibility of the coupling and the office environment.Generally, couplings made of metal material components that do not need to be lubricated are more reliable; couplings that must be lubricated are easily affected by the sound level of lubrication and are likely to cause environmental pollution.Couplings with non-metallic components such as vulcanized rubber are more sensitive to temperature, corrosive substances and strong light, and are very easy to embrittlement.

5) Due to manufacturing, installation, load deformation and temperature change, after installation and adjustment, it is impossible to maintain the strict and precise alignment of the two shafts.There is a certain level of x, Y azimuth offset and skew angle CI.When the axial deviation is large, the slider coupling can be selected, the angular velocity is large or the universal coupling can be used for the connection of the two shafts.When the two shafts cause a large extra relative displacement during the whole process of work, a flexible coupling should be used.
