Problems solved by technology

[0002] Track rollers are the key components of the tracked paddy field tractor's walking system. The sealing of the track rollers directly affects the service life of the track rollers. Paddy field tractors often work in harsh working environments such as muddy water, and muddy water can easily penetrate the wheel train through the gaps. In the sealing structure, it will cause wear to the shaft and bearing, cause the sealing performance to fail, reduce the service life of the roller, and affect the normal operation of the wheel train

Embodiment Construction

[0025] Such as figure 1 and 2 as shown, figure 1 It is a structural schematic diagram of the oil seal assembly for the roller bearing of the paddy field tractor proposed by the present invention, figure 2 It is a structural schematic diagram of the second-order seam sealing structure for paddy field tractor roller bearings proposed by the present invention.

[0026] refer to figure 1 , the oil seal assembly for roller bearings of paddy field tractors proposed by the present invention and its second-order seam seal structure include: a first oil seal 1 and a second oil seal 2;

[0027] The first oil seal 1 includes a first skeleton and a first rubber vulcanized on the outside of the first skeleton. The first skeleton includes an inner fixing sleeve 11, a first ring body 12, and a second ring body 13. One end of the inner fixing sleeve 11 is provided with a The protruding first support plate 14, the first ring body 12 and the second ring body 13 are sequentially sleeved out...

Abstract

The invention discloses an oil seal assembly for a roller bearing of a paddy field tractor and a second-order seam sealing structure. The inner fixed sleeve of the first oil seal is provided with a first ring body and a second ring body in sequence, and the outer surface of the second oil seal The fixing sleeve is set outside the second ring body, the first sealing protrusion of the second oil seal extends between the first ring body and the second ring body, and the second sealing protrusion extends between the ring body and the inner fixing sleeve, Thus, two oil seal chambers are formed between the inner fixed sleeve of the first oil seal and the outer fixed sleeve of the second seal; the oil seal assembly for the track roller bearing of the paddy field tractor of the present invention is fixed in the inner fixed sleeve of the first oil seal. The first ring body and the second ring body are arranged outside the sleeve, so that the two sealing protrusions of the second seal form a double sealing structure with it, which greatly improves the sealing effect, thereby effectively reducing the wear of the oil seal and prolonging the service life. The invention also proposes a second-order seam sealing structure for the roller bearing of the paddy field tractor, which effectively prevents muddy water from entering the bearing.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to an oil seal assembly for a roller bearing of a paddy field tractor and a second-order sealing structure thereof. Background technique [0002] Track rollers are the key components of the tracked paddy field tractor's walking system. The sealing of the track rollers directly affects the service life of the track rollers. Paddy field tractors often work in harsh working environments such as muddy water, and muddy water can easily penetrate the wheel train through the gaps. In the sealing structure of the bearing, it will cause wear to the shaft and bearing, cause the sealing performance to fail, reduce the service life of the roller, and affect the normal operation of the wheel train. The sealing of the rollers has a great influence on the normal operation of the wheel train, and strengthening the sealing effect of the rollers can also improve the service life of the bearings and ...
