The mechanical structure will produce different vibration characteristics due to different factors such as structure, material, motion mechanism, etc., which can be called the structural mode of the machine, and then after normalizing treatment, rough machining is carried out, and quenching and tempering treatment should be carried out after rough machining to ensure that the overall mechanical properties of the elastic pin coupling reach its performance state, and finishing is carried out after quenching and tempering treatment.
Elastic pin coupling
The axial and angular stiffness are much smaller and can be easily damaged if misused in use or not installed correctly. The torsional stiffness and radial stiffness are very large, and the radial stiffness is close to the stiffness of general rolling bearings. A large extrusion force is generated on the axial retaining ring, and if this extrusion force is large enough, it may be an axial limit failure. As a result, the end cap bolt is loose or broken, and the roller is squeezed out or even falls off due to the oscillating extrusion force of the jacket.
Elastic pin coupling
The centering of the two axes is very high, if the relative displacement of the two axes occurs, it seriously affects the normal operation of the shaft and the bearing, and the shock can not be mitigated and the vibration can not be absorbed when the load is transmitted. When working under the condition that there is a relative displacement between the two shafts, the intermediate disc will produce a large centrifugal force, thereby increasing the dynamic load and wear, so it should be noted that the working speed should not be greater than the specified value. The work surface needs to be heat treated to increase its hardness, not heat treated. In order to reduce friction and wear, oil should be injected into the oil hole of the intermediate disc for lubrication.
Elastic pin coupling
The pressure can make the coupling have zero backlash operation in the operation of the equipment, and with the increase of service time, it may lose its function without recoil due to wear, and it can still exert its original performance after replacement. The allowable value of torque in actual use, the allowable value of the mutual angle formed between the two axes, and the allowable value of the parallel deviation of the axes of the two axes.
