Embodiment Construction

[0031] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0032] Example figure 2 As shown, the supporting wheels in the crawler-type mechanical traveling mechanism include a roller shaft 1 and a roller body 2 sleeved on the roller shaft 1, and a bushing 3 with bearing bushes is arranged between the roller body 2 and the roller shaft. The above-mentioned axle sleeve with the bearing bush is closely fitted and fixed with the outer roller body.

[0033] The bushing with bearing bush is a bimetallic bushing, the outer ring of the bushing and the roller body 2 are closel...

Abstract

The invention discloses a roller in a caterpillar mechanical travelling mechanism, which comprises a roller shaft (1), and a roller body (2) sleeved on the roller shaft (1). A shaft sleeve (3) with a bearing bush is arranged between the roller body (2) and the roller shaft. The roller is characterized in that: the shaft sleeve with the bearing bush is closely fitted and fixed with the roller body on the outer side. After the roller body is subjected to half-body finish machining, the shaft sleeve with the bearing bush is directly closely fitted and fixed with the roller body; and then the roller is welded for forming after the roller shaft is assembled, thereby canceling the machining on an iron sleeve, the roller body and a screwed hole of the iron sleeve, simplifying the structure of the roller in caterpillar mechanical chassis parts, increasing the assembly efficiency, reducing the cost, improving the product quality, and enhancing the production efficiency. The roller can be applied in the chassis parts of small and medium-sized engineering machinery, construction machinery, small and medium-sized agricultural machinery and small and medium-sized special machinery.

Description

technical field [0001] The invention belongs to the technical field of crawler machine chassis component design in the technical field of construction machinery. [0002] In particular, it relates to a roller in a crawler-type mechanical traveling mechanism. Background technique [0003] The crawler-type construction machinery traveling device is divided into a crawler traveling device with a roller and a crawler traveling device without a roller according to the presence or absence of a roller. Since the crawler belt traveling device without supporting wheels mainly has sliding friction when walking, the wear is relatively serious, and the application range is small. The track running device with rollers is mainly composed of "four wheels and one belt", namely track, driving wheel, roller, supporting sprocket, tensioning device, track frame, etc. During operation, the driving wheel generates a relay force on the tight side of the track, the driving section and the groundi...
