Shape circumferential groove facilitates being coupled for the resilient sleeve and the sliding block.
Further, the length of the resilient sleeve is 2-4mm longer than the sliding block, and the assembly height of the position-limitting pin is greater than
The radius of the sliding block circular hole, after preventing the resilient sleeve aging from deforming, the sliding block falls off from the sliding pin rod.
Further, buphthalmos ball two sides are equipped with cyclic annular side elongate structure outstanding, can prevent the sliding pin
Bar contacts when rotating with the fork arm external cylindrical surface, causes contact area excessive wear.
Acquired beneficial effect is using the above scheme：
1, compact-sized, simple, it is convenient to process and mount, driven load is big, long service life, high reliablity, realizes big
The transmitting of torque.
2, buphthalmos ball uses bilateral elongate structure, effectively avoids the fortune that pin rod is slided during transmission
It is dynamic, it is contacted with the surface of the fork arm of three fork arm output shaft ends, causes the abrasion on its surface.
3, the sliding Hooks coupling universal coupling input shaft end axis of three fork arm spring column pin formulas and three fork arm output shaft end axis
Maximum allowable corner is 45 °, and angle compensation and axial displacement compensation not only may be implemented, can also compensate for a small amount of radial positions
Move compensation.
4, due to flexible set between sliding pin rod and input shaft end, have the function of buffering absorbing, can effectively reduce
Shock loading in starting impact and the course of work, protects other components by impact injury.
5, the sliding slot of input shaft end is open, not only facilitates the addition of lubricant, but also be conducive to sliding block in work
Scattering and disappearing due to the generated heat that rubs in the process.
