Abstract
The utility model discloses a kind of rocker arm shaft thread bush and the wear-resistant structure of adjusting screw, including rocker arm shaft, thread bush and adjusting screw, wear-resistant packing ring is provided between the annular end face of thread bush and adjusting screw lower end, copper-based tin alloy powder sintering layer is provided with the surface that the wear washer is in contact with thread bush.The abrasion resistance properties of the wear washer are less than the thread bush and the anti-wear performance of adjusting screw.The utility model has the advantages of long lifespan and low cost compared with the prior art.
Description
Technical field
It the utility model is related to the wear-resistant knot of a kind of vapour steering gear, particularly a kind of rocker arm shaft thread bush and adjusting screw
Structure.
Background technology
Make periodically to swing when rocker arm shaft works, because rocker arm shaft has lower surface and the regulation that downward power makes thread bush
The annular end face of screw termination produces friction and wear, causes steering gear service life reduction, and replacing rocker arm shaft and thread bush into
This is higher.
The content of the invention
The utility model purpose is to provide the low a kind of rocker arm shaft thread bush of a kind of long lifespan and cost and adjusting screw
Wear-resistant structure.
The technical solution of the utility model is, including rocker arm shaft, thread bush and adjusting screw, it is characterised in that：In screw thread
Wear-resistant packing ring is provided between set and the annular end face of adjusting screw lower end, in the table that the wear washer is in contact with thread bush
Face is provided with copper-based tin alloy powder sintering layer.The abrasion resistance properties of the wear washer are less than the thread bush and adjusting screw
Anti-wear performance.
The utility model has the advantages of long lifespan and low cost compared with the prior art.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is solves the defects of above-mentioned prior art is present, using technical scheme as shown in Figure 1, in screw thread
Wear-resistant packing ring 4 and packing ring 5 are arranged in adjusting screw between set 2 and the annular end face of the lower end of adjusting screw 1, wherein wear-resistant
The surface that damage packing ring 4 is in contact with thread bush is provided with wear-resistant friction layer, and the material of the wear-resistant friction layer is copper-based tin alloy powder sintering
Layer, the method to set up of the damage-retardation layer are the first copper facing on the surface of wear-resistant packing ring, then by copper-based tin alloy powder sintering anti-
On the surface of wear washer, wear-resistant sinter layer is formed.The external screw thread of thread bush matches with the internal thread of rocker arm shaft 3, packing ring 5
It can be not provided with.
Claims (2)
