Problems solved by technology

The structural design of the supporting sprocket in the prior art is complicated, and it is generally fixed by a shaft fixedly protruding from the mounting seat of the track beam. During use, it is easy to tear the mounting seat due to vibration, and the supporting sprocket is stressed. Uneven premature wear and other issues
In addition, due to the complex internal structure of the carrier sprocket, its internal seal is not tight, and there is a risk of lubricating oil leakage, which will greatly increase the use and maintenance costs of the tracked vehicle using this carrier sprocket

Embodiment Construction

[0020] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0021] attached figure 1 A sectional view of a carrier roller 10 for supporting a track in a tracked vehicle such as an excavator according to the present invention is shown. Refer to the attached figure 1 The specific structure of the carrier roller 10 for supporting the track according to the present invention will be described in detail. The carrier roller 10 according to the present invention includes a main shaft 12 and a wheel body 14 rotatably provided on an outer peripheral wall of the main shaft 12 . The main shaft 12 supports the wheel body 14, and when the wheel body 14 supports the crawler belt, the wheel body 14 can rotate around the main shaft 12 during the running of the tracked...

Abstract

The invention relates to a supporting chain wheel for a track-laying vehicle. The supporting chain wheel comprises a main shaft, a wheel body rotationally arranged on the outer peripheral wall of the main shaft and a bearing part for supporting the main shaft and the wheel body by an installation seat of a track beam of the vehicle. The bearing part comprises two end seats arranged on the two sides of the main shaft respectively. The two end seats provide the bearing effect for the main shaft at the two ends of the main shaft, and the end seats are matched with the ends of the main shaft through center holes formed in the end seats. Due to the fact that the supporting chain wheel provides the bearing effect for the main shaft at the two ends of the main shaft, the risks that the supporting chain wheel is deformed in the axis direction and is even broken due to single-end bearing can be effectively avoided, a track is well borne and more stably moves, and then the track-laying vehicle can more stably and safely run. Due to the fact that the supporting chain wheel is not prone to deformation and is longer in service life, the use and maintenance cost of the track-laying vehicle can be greatly reduced.

Description

technical field [0001] The invention relates to a support roller, in particular to a support sprocket used for a tracked vehicle and providing support for the track. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The supporting sprocket is an important part in the running mechanism of a crawler vehicle such as an excavator. It is mainly used to hold up the upper track, prevent the upper track from drooping excessively, and support the track to ensure the normal operation of the track. In addition, the supporting sprocket is also an easily damaged component in the tracked vehicle. Since the working conditions of the tracked vehicle are generally more complicated, the technical requirements for the supporting sprocket are relatively high. The structural design of the supporting sprocket in the prior art is comp...
