Embodiment Construction

[0021] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0022] like Figure 1-3 As shown, a new wear-resistant sheave includes a wheel body 1, a rope groove 8 is provided on the outer surface of the wheel body 1, and a rope groove washer 5 is sleeved inside the rope groove 8. An installation hole is opened at the center of the side end surface of the wheel body 1 , and the installation hole includes a snap ring 3 and an inner hole 6 . The inner diameter of the snap ring 3 is greater than the inner diameter of the inner hole 6, and the inner diameter of the snap ring 3 is provided with a snap ring sleeve 4, and the inner hole 6 is provided with an inner hole sleeve 7, and the rope groove washer 5 , The material of the snap ring sleeve 4 and the inner hole sleeve 7 is wear-resistant high manganese steel metal material.

[0023] By setting the wear-res...

Abstract

The invention provides a novel wear-resistant sheave, which includes a wheel body, a rope groove is provided on the outer surface of the wheel body, a rope groove washer is set inside the rope groove, and the side end surface of the wheel body A mounting hole is opened at the center, the mounting hole includes a snap ring and an inner hole, the inner diameter of the snap ring is larger than the inner diameter of the inner hole, the inner sleeve of the snap ring is provided with a snap ring sleeve, and the inner sleeve of the inner hole An inner hole sleeve is provided, and the material of the rope groove washer, the snap ring sleeve and the inner hole sleeve is wear-resistant high manganese steel metal material. The beneficial effect of the present invention is: by setting the rope groove washer, the snap ring sleeve and the inner hole sleeve, the wear degree of the steel wire rope and the shaft body to the wheel body is reduced; the rope groove washer, the The clasp ring sleeve and the inner hole sleeve are designed as high manganese steel metal material because this material has the characteristic that the surface is stronger when it is subjected to external impact force, while its interior still maintains the original toughness. The first choice for wear-resistant materials in the industry.

Description

technical field [0001] The invention relates to the technical field of elevator components, in particular to a novel wear-resistant sheave. Background technique [0002] With the rapid development of the construction industry, the elevator manufacturing industry is also showing a prosperous scene. Now the elevator has become an indispensable tool for people to go up and down the stairs. One of the lifting power transmission components of the elevator is the sheave. The steel wire rope provides the pulling force required for the elevator to go up and down, and the sheave that is sheathed with the steel wire rope has the function of changing the pulling force direction of the steel wire rope. The two rely on static friction to operate normally. Because the tension value provided by the wire rope is relatively large, the pressure of the wire rope on the sheave will be very large, so the static friction between the two will also be very large. This will make the friction bet...
