Description

Detachable thrust wheel

Technical Field

The utility model relates to a thrust wheel technical field specifically is a removable thrust wheel.

Background

The thrust wheel is one of four wheels of a chassis of the crawler-type engineering machinery, and mainly has the functions of supporting the weight of the excavator and the bulldozer and enabling the crawler to move forward along the wheel.

In the moving process of the existing supporting wheel, only the supporting shaft and the end cover rotate (other supporting shafts do not move), lubricating oil in the oil filling cavity can lubricate the bimetallic sleeve and the sealing O-shaped ring, so that the lubricating oil cannot play a good lubricating role, the oil leakage defect can be caused due to the fact that the lubricating oil cannot be lubricated in time, and optimization is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a removable thrust wheel to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

The detachable thrust wheel comprises a thrust wheel fulcrum shaft assembly, wherein a thrust wheel side cover matched with the thrust wheel fulcrum shaft assembly is sleeved outside the thrust wheel fulcrum shaft assembly, an oil injection bolt hole is formed in the thrust wheel side cover, and an oil cavity through hole communicated with the oil injection bolt hole is further formed in the inner wall of the thrust wheel side cover.

As a further technical solution of the present invention: and a sealing ring is arranged between the thrust wheel side cover and the thrust wheel fulcrum shaft assembly.

As a further technical solution of the present invention: and a sheath is also arranged between the thrust wheel side cover and the thrust wheel fulcrum shaft assembly, and is sleeved outside the thrust wheel fulcrum shaft assembly.

As the utility model discloses a further technical scheme again: the fulcrum wheel fulcrum assembly includes a first fulcrum and a second fulcrum threadedly coupled thereto.

As the utility model discloses a further technical scheme again: the first fulcrum shaft is fixedly provided with a threaded column, and the second fulcrum shaft is provided with a threaded groove matched with the threaded column.

Compared with the prior art, the beneficial effects of the utility model are that: through setting up oiling bolt hole and oil pocket through-hole cooperation for the thrust wheel is in time lubricated contact with lubricating oil at the rotation in-process, and is lubricated effectual, long service life, and thrust wheel fulcrum shaft assembly has two threaded connection's fulcrum shaft to constitute moreover, conveniently carries out the dismouting when breaking down, can pour into new lubricating oil into simultaneously when the dismouting, and is more practical.

Drawings

FIG. 1 is a cross-sectional view of a removable thrust wheel;

FIG. 2 is a cross-sectional view of a pivot shaft assembly of the removable pivot wheel.

In the figure: 1-fulcrum wheel fulcrum shaft assembly, 2-fulcrum wheel side cover, 3-oiling bolt hole, 4-oil cavity through hole, 5-sealing ring, 6-sheath, 7-first fulcrum shaft, 8-second fulcrum shaft, 9-threaded column and 10-threaded groove.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

As shown in fig. 1, 2 removable thrust wheel, including thrust wheel fulcrum shaft assembly 1, the outside cover of thrust wheel fulcrum shaft assembly 1 is equipped with rather than matched with thrust wheel side cap 2, oiling bolt hole 3 has been seted up on thrust wheel side cap 2, still set up the oil pocket through-hole 4 that is linked together with oiling bolt hole 3 on the thrust wheel side cap 2 inner wall, come to pour into lubricating oil into to inside through seting oiling bolt hole 3 promptly, then through whole contact surface of oil pocket through-hole 4 flow through, thereby make in thrust wheel rotation in-process, refuel the lubricating oil in the appearance chamber and can in time lubricate the oil blanket to lubricating oil can in time pour into lubricating oil into through oiling bolt hole after having consumed, play the effect of in time supplementary lubricating oil, only need take out the bolt of inside during the injection, wait to pour into after finishing on sealing can, convenient operation.

Furthermore, a sealing ring 5 is arranged between the thrust wheel side cover 2 and the thrust wheel fulcrum shaft assembly 1, so that the sealing effect is improved, and the loss of lubricating oil is reduced.

Furthermore, a sheath 6 is further installed between the thrust wheel side cover 2 and the thrust wheel fulcrum shaft assembly 1, the sheath 6 is sleeved outside the thrust wheel fulcrum shaft assembly 1, and the sheath 6 is preferably a double-metal sleeve, so that the service life of the thrust wheel can be effectively prolonged.

Example 2

The present embodiment is further optimized based on embodiment 1, and the pivot shaft assembly 1 includes the first pivot shaft 7 and the second pivot shaft 8 screwed thereto, that is, the first pivot shaft 7 and the second pivot shaft 8 are assembled in the pivot side cover 2 by screwing, so that the pivot shaft assembly can be easily assembled and disassembled when the pivot shaft assembly is disassembled, and new lubricating oil can be injected when the pivot shaft assembly is disassembled.

Further, a threaded column 9 is fixedly mounted on the first fulcrum 7, and a threaded groove 10 matched with the threaded column 9 is formed in the second fulcrum 8, that is, the threaded connection between the first fulcrum 7 and the second fulcrum 8 is realized through the matching of the threaded column 9 and the threaded groove 10.
