Kinematic pair, for realizing the movement of mechanism；And pin shaft belongs to stationary parts, this requires the installations of pin shaft to realize axial and circle
Positioning on week prevents the play between axis and bearing, influences the service life of components.
Prior art be usually pin shaft is processed as it is ladder-like, then assist with pressing plate realize pin shaft axially position；
Circumferential registration is realized by increasing other ancillary structural members.Structure is complex on the whole, manufacturing cost is high.
Utility model content
The technical issues of the utility model is solved is to provide a kind of mine car oscillating bearing pin shaft location structure, and pin shaft is set
It is calculated as simple plain shaft structure, the axial direction and circumferential registration of pin shaft are realized by limit hole and tight fixed bolt, simple with structure,
The advantages of anufacturability is good, high reliablity.
Technical solution is as follows:
A kind of mine car oscillating bearing pin shaft location structure, comprising: the first connector, the second connector, pin shaft, joint shaft
It holds, the first spacer ring, the second spacer ring, the first bushing, the second bushing, the first tight fixed bolt；Oscillating bearing, the first spacer ring, second every
Circle, the first bushing, the second bushing are sleeved on pin shaft, and oscillating bearing is mounted on the second connector, the first spacer ring, the second spacer ring
Oscillating bearing two sides are separately positioned on, the first bushing, the second bushing are located at the outside of the first spacer ring, the second spacer ring；First
Connector is provided with first shaft hole and the second axis hole, and first through hole, the second through-hole are provided on the tube wall of the second axis hole, and pin shaft is set
It is equipped with third through-hole；The both ends of pin shaft are separately mounted in first shaft hole and the second axis hole；First tight fixed bolt sequentially passes through
Nut check is used after one through-hole, third through-hole, the second through-hole.
Further, tapped through hole is provided on the tube wall of first shaft hole, the second tight fixed bolt is connected on tapped through hole.
Further, first through hole, the second through-hole are located at the upper and lower part of the tube wall of the second axis hole, are located at same axis
On.
Further, third through-hole is vertical with the axis of pin shaft.
The utility model technical effect includes:
Pin shaft is designed as simple plain shaft structure in the utility model, and the axis of pin shaft is realized by limit hole and tight fixed bolt
To and circumferential registration, have the advantages that structure is simple, anufacturability is good, high reliablity.Realize that the tight fixed bolt of positioning is logical
With standard component, manufacturing cost is low.
