Background
With the rapid development of economy, the thrust wheel is one of four wheels and one belt in crawler-type chassis of an excavator, a bulldozer and the like, and the thrust wheel mainly plays a role in supporting the weight of the excavator and the bulldozer and enabling a crawler to advance along the wheel; a copper sleeve or a bimetallic sleeve is arranged in a thrust wheel of the existing crawler belt travelling mechanism, the copper sleeve is used as a sliding bearing, and lubricating oil is filled in the copper sleeve; a gap is reserved between the thrust wheel shaft and the copper sleeve so as to store lubricating oil; the sealing of thrust wheel lubricating oil adopts floating oil seal to seal, adopts the thrust wheel of copper sheathing with floating oil seal structure promptly, because the trade competition is big, and then makes the price frequency of thrust wheel decline, and the cost of copper sheathing with floating oil seal structure's thrust wheel is with high costs makes manufacturer's profit low.
SUMMERY OF THE UTILITY MODEL
Therefore, aiming at the problems, the utility model provides a novel thrust wheel which is simple and reasonable in structure, low in manufacturing cost, good in sealing performance and durable, and can improve the production profit of enterprises.
In order to solve the technical problem, the utility model adopts the following scheme: the utility model provides a novel thrust wheel, includes thrust wheel body, first side cap, second side cap and thrust wheel axle, it is internal that thrust wheel axle rotationally wears to locate thrust wheel, first side cap and second side cap pass through the round pin hub fixation at the both ends of thrust wheel axle and first side cap and second side cap respectively with thrust wheel body both ends terminal surface interference fit, the fitting surface of thrust wheel body and first side cap, second side cap and thrust wheel axle is the mirror surface of polish processing, the fitting surface of first side cap and second side cap and thrust wheel body is the mirror surface of polish processing, the fitting surface of thrust wheel axle and thrust wheel body is the mirror surface of polish processing, respectively built-in butter between thrust wheel body and first side cap, second side cap and the thrust wheel axle.
In a further improvement, O-shaped rings are respectively arranged between the end surfaces of the two ends of the thrust wheel body and the matching end surfaces of the first side cover and the second side cover.
By adopting the technical scheme, the utility model has the beneficial effects that: through with the thrust wheel body, the thrust wheel axle, the fitting surface between first side cap and the second side cap all sets to the mirror surface of roller burnishing processing, and thrust wheel body and first side cap, embed grease lubricating oil between second side cap and the thrust wheel axle respectively, utilize the consistency cooperation mirror surface of butter to make the thrust wheel can operate fast and stably, sealing performance is good, high durability, the structure setting of copper sheathing and oil seal ring has been saved, greatly reduced the cost of production, effectively improve the production profit of enterprise, simple structure is reasonable, through further setting, it can further ensure the butter does not leak to set up O type circle respectively between thrust wheel body both ends terminal surface and first side cap and the second side cap cooperation terminal surface promptly, strengthen between the thrust wheel body and the thrust wheel axle with rotating ground stable in structure, can extensively popularize and apply.
