Pawl is equipped with connection pawl bolt hole, is equipped on flange and spacer ring and connect the one-to-one bolt hole of pawl bolt hole, the method
Bolt hole on orchid is the flange stepped hole being made of flange diameter holes and flange large diameter hole, and the bolt hole on spacer ring is small by spacer ring
The spacer ring stepped hole in diameter hole and spacer ring large diameter hole composition, in all connection pawl bolts hole, at least 2 connect and are set in pawl bolts hole
The diameter of bore D1 of flexible pin, resilient key is respectively less than the diameter D2 of flange diameter holes and the diameter D2 of spacer ring diameter holes, elasticity
The front end of pin is inserted into corresponding flange large diameter hole, and the rear end of resilient key is inserted into corresponding spacer ring large diameter hole, and bolt passes through method
Blue stepped hole, connection pawl bolt hole and spacer ring stepped hole, tail portion are pierced by spacer ring, and 1 ~ 2 disc spring film is connected on tail portion,
It is fixed by self-locking nut.
The resilient key and flange large diameter hole, to connect pawl bolt hole and spacer ring large diameter hole be interference fit.
The difference of the diameter D2 of the flange diameter holes or the diameter D2 and D1 of spacer ring diameter holes are between 0.5 ~ 1.5mm.
The both ends of the resilient key are respectively provided with chamfering
The bolt is hex bolts, and the front end of flange stepped hole is equipped with hexagonal counterbore, and the part on the head of bolt is placed in
In hexagonal counterbore.
Combination bore is constituted by flange large diameter hole, connection pawl bolt hole and spacer ring large diameter hole, the length H1 of resilient key is less than group
Close the length H2 in hole.
The difference of the length H2 of combination bore and the H1 of resilient key are between 0.5 ~ 2mm.
The utility model has following good effect：1. since the diameter of bore of resilient key is respectively less than flange path bore dia
With spacer ring path bore dia, the Self-centering Action in hub, disk body and spacer ring assembling process had both been played in this way, and in train height
In fast operational process, disk body and hub will not generate bias, avoid causing rotation imbalance because of disk body, hub position inaccurate
Axle vibration problem caused by and.2. since the bolt hole on flange and spacer ring is stepped hole, flange large diameter hole and spacer ring major diameter
Hole is used to support resilient key, only by bolt by hole be diameter holes, the port size on such flange and spacer ring is smaller, dish
The contact surface of spring leaf and spacer ring is larger, after abrasion occurs in joint face, by the deflection of disc spring film, can still protect
It holds bolt to be reliably connected, makes brake disc arrangement that there is reliable anti-loosening property, sink in addition, the part on the head of bolt is placed in hexagonal
Kong Zhong can be effectively prevented bolt rotation, enhance the anti-loose ability of bolt, nut.4. due to the diameter of bore of resilient key
It, only need to be in the diameter holes of flange or spacer ring when dismantling brake disc part less than flange diameter holes and spacer ring path bore dia
Suitable plug is placed, the dismounting that resilient key can be completed in plug is tapped with copper rod, it is time saving and energy saving.
