Rubber-coated track pin

Abstract

The invention provides a rubber-coated track pin. The rubber-coated track pin comprises a track pin body and rubber rings; the rubber rings are adhered to the track pin body; a circular pipe is arranged in each rubber ring; and the rubber rings are layered by the round pipes. The rubber rings with small hardness and large elasticity are adopted, one or more layers of round pipes are arranged in the rubber rings for restraining, the round pipes restrain the rubber rings, the rubber rings have enough hardness, when the rubber rings move under horizontal stress, the round pipes enable the rubber rings to be small in deformation in the horizontal direction, and the deformation amount consistent with that of a traditional rubber ring with large hardness is kept, so that a track product specification is met; and meanwhile, the round pipes do not influence deformation of the rubber in the annular direction, the rubber rings are kept to have the characteristics of large deformation and good torsion, and the problems that a traditional rubber ring slips and is abraded, and the traditional rubber ring is heated and loses elasticity due to high temperature generated by excessive deformation are solved.

Description

technical field [0001] The invention relates to a rubberized track pin. Background technique [0002] The existing glue-hanging track pins all adopt the technology of track pin hanging glue, that is, glue the rubber ring on the track pin, and then press the track pin with the rubber ring into the track pin ear, and the tightness of the assembled track pin should reach the rubber ring The degree to which the pin lug cannot turn even with sufficient friction. [0003] At present, rubber rings with low hardness and good elasticity cannot be used in the production of crawler pins, because the hardness of the rubber ring is low, the elasticity is large, and the deformation is large. Although the torsional force is sufficient, there are the following problems: figure 1 , figure 2 As shown, when the traditional rubber ring 5 is subjected to horizontal extrusion force, the greater the elasticity, the greater the deformation of the traditional rubber ring 5, and the displacement i...

Problems solved by technology

[0003] At present, rubber rings with low hardness and good elasticity cannot be used in the production of crawler pins, because the hardness of the rubber ring is low, the elasticity is large, and the deformation is large. Although the torsional force is sufficient, there are the following problems: figure 1 , figure 2 As shown, when the traditional rubber ring 5 is subjected to horizontal extrusion force, the greater the elasticity, the greater the deformation of the traditional rubber ring 5, and the displacement in the horizontal direction will increase accordingly, and the crawler will become " Loose” does not meet the parameter requirements of the track; therefore, the hardness of the rubber ring used in the existing track pins is relatively large, so that when it is subjected to horizontal extrusion force, the displacement in the horizontal direction meets the parameter requirements of the track, but there are also the following Problem: The deformation of the rubber ring is small, resulting in poor torsion, prone to slipping, wear and other problems, and due to the small deformation, if the deformation is too large during exercise, the rubber ring will generate a lot of heat, causing the rubber ring to heat up and lose its elasticity ;The above problems cause the track pins to be replaced and repaired frequently, which increases the maintenance cost
