Embodiment Construction

[0020] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0021] Such as figure 1 , 2 As shown, an easy-to-install wear-resistant double-sided support wheel includes a wheel body 1, and both axial ends of the wheel body 1 are floating sealing ends 2, and the floating sealing ends 2 form coaxial The shaft seat assembly hole 3 and the floating seal ring assembly hole 4, the hole bottom of the floating seal ring assembly hole 4 includes an arc-shaped bottom wall away from the axis and a straight bottom wall close to the axis. The wear-resistant sheet assembly ring groove 5 of the grinding sheet forms a guide assembly groove 6 at the opening of the wear-resistant sheet assembly ring groove 5, and the groove wall of the guide assembly groove 6 is a conical surface.

[0022] The taper of the groove wall of the guide assembly groove 6 is adapted to the taper of the tapered portion of the fixed end of the wear-resistant sheet...

Abstract

The invention discloses an easy-to-install wear-resistant double-sided supporting wheel, which includes a wheel body, and the two axial ends of the wheel body are floating sealing ends, and the floating sealing ends form a coaxial shaft seat assembly sequentially from the outside to the inside. hole, the assembly hole of the floating seal ring, the hole bottom of the assembly hole of the floating seal ring includes an arc-shaped bottom wall away from the axis and a straight bottom wall close to the axis, and a wear-resistant sheet for accommodating the wear-resistant sheet is formed in the flat bottom wall An assembly ring groove, the opening of the wear-resistant sheet assembly ring groove forms a guide assembly groove, and the groove wall of the guide assembly groove is a conical surface. The invention realizes the assembly of the floating seal rubber ring through the arc-shaped bottom wall of the assembly hole of the floating seal ring, and separates and fixes the wear-resistant sheet through the wear-resistant sheet assembly ring groove in the flat bottom wall. At the same time, the guide assembly groove can Grinding discs are positioned and radially limited. The invention can effectively improve the service life and production efficiency of the supporting wheels.

Description

technical field [0001] The invention belongs to a track roller for a crawler vehicle, in particular to an easy-to-install and wear-resistant double-sided roller. Background technique [0002] The supporting wheel is one of the four-wheel belts of the crawler-type construction machinery chassis. Its main function is to support the weight of the excavator and bulldozer, so that the track moves along the wheels. [0003] Rollers can be divided into unilateral rollers and double-sided rollers; rollers for excavators and rollers for bulldozers. The rollers for excavators are generally black paint, and the rollers for bulldozers are generally yellow paint. [0004] Roller wheel body material is generally 50Mn, 40Mn 2 , and other materials, the main process is casting or forging, machining, and then heat treatment. The hardness of the wheel surface after quenching should reach HRC45~52 to increase the wear resistance of the wheel surface. The processing accuracy of the supporting...
