Description

Tracked agricultural machinery support roller Technical Field

[0001] This invention relates to engineering machinery, and more particularly to a tracked agricultural machinery support roller. Background Technology

[0002] Track rollers are installed in the chassis of tracked construction machinery to support the body of the machinery and guide the movement of the tracks. Technical issues

[0003] The hub of commonly used tracked track rollers is a one-piece structure. However, during operation, dirt and grime accumulate on both sides of the track roller. During cleaning and maintenance, the one-piece spokes obstruct water flow, making it difficult for the dirt and grime inside the track roller to be discharged. Furthermore, the one-piece hub locating ring is prone to overheating during operation, causing the protective rubber layer to peel off, adversely affecting the normal operation of the tracked machinery and reducing its service life. Therefore, it is necessary to optimize the structure of this track roller to overcome these shortcomings. Technical solutions

[0004] The purpose of this invention is to provide a tracked agricultural machinery support roller that facilitates cleaning and maintenance, dissipates heat at high temperatures, and increases service life.

[0009] A transition support component is connected between the wheel axle positioning ring and the wheel hub positioning ring, and the wheel hub positioning ring is supported by the transition support component;

[0010] A protective rubber layer is vulcanized on the wheel hub locating ring, which provides protection and cushioning for the wheel hub locating ring.

[0011] The adapter support has a hollow structure, through which the two sides of the adapter support are connected.

[0012] The adapter support includes:

[0013] Supporting ribs are provided with a group of supporting ribs, each of which is arranged along the circumference of the wheel shaft positioning ring and the wheel hub positioning ring in sequence, and the two ends thereof are connected to the inner wall of the wheel hub positioning ring, and the middle part thereof is connected to the outer wall of the wheel shaft positioning ring, and a hollow structure is formed between the supporting ribs and the wheel shaft positioning ring and the wheel hub positioning ring.

[0014] The supporting ribs are arc-shaped, the middle part thereof protrudes towards the wheel shaft positioning ring, and the two ends thereof extend towards the wheel hub positioning ring.

[0015] The supporting ribs are provided with 6 supporting ribs, each of which is uniformly arranged along the circumference of the wheel shaft positioning ring and the wheel hub positioning ring, and the adjacent supporting ribs are connected to each other and form an included angle of 220°, so that the integrity of the adapter support is better.

[0016] The middle part of the supporting rib has an adapter rib, which extends along the axial direction of the wheel shaft positioning ring and protrudes outwardly from the supporting rib, and the supporting rib is connected to the outer wall of the wheel shaft positioning ring through the adapter rib.

[0017] The inner wall of the wheel shaft positioning ring is provided with a positioning step, which cooperates with the bearing and oil seal of the wheel shaft, and the outer ring of the bearing and the oil seal is connected to the inner wall of the positioning step, and the inner ring is connected to the wheel shaft.

[0018] The axial length of the supporting rib and the adapter rib is less than the axial length of the wheel shaft positioning ring and the wheel hub positioning ring, so as to avoid interference with the outside.

[0019] The edge of the wheel hub positioning ring is provided with a chamfered part.

[0020] The wheel shaft positioning ring, the wheel hub positioning ring, the supporting rib and the adapter rib are integrally formed.
