And connected by the oil filler point of wheel shaft mounting hole and fixing bolt with outside, so that bearing grease up is become very convenient, prolongs
The service life for having grown bearing, also greatly reduces maintenance cost and time.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
1. wheel shaft in figure, 11. mounting holes, 2. bearings, 3. wheel bodys, 4. fixing bolts, 41. oil filler points, the installation of 5. vehicle frames
Plate, 6. left covers, 7. right cover plates, 8. retaining rings, 9. shaft retaining rings, 10. pump nozzles.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of wheel lubrication system of the present embodiment, for the lubrication of inside wheel bearing, as shown in Figure 1, vehicle
Wheel includes wheel shaft 1, bearing 2 and wheel body 3, and bearing is two pieces, and retaining ring 9, the left part installation of wheel shaft are equipped between two pieces bearing
There is shaft retaining ring 8, the inner ring of bearing is sheathed on wheel shaft, and wheel body is sheathed on the outer ring of bearing, and wheel shaft central design has perforation to take turns
