Problems solved by technology

The traditional friction plate is a phenolic resin with a high content of glass fiber with good wear resistance and self-lubricating properties. This high content of glass fiber is easy to disperse unevenly in the phenolic resin and lead to agglomeration. During lathe processing, the agglom

Embodiment Construction

[0013] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 As shown, the embodiment of the present invention discloses a noiseless elevator roller assembly, comprising a wheel hub 10 made of nylon material with a weight of 49.0-70.0, a polyurethane elastic bead 20 formed on the surface of the wheel hub 10, mounted on the wheel hub The bearing 30 inside the hub 10, and the friction plates 40 located on both sides of the hub 10. Wherein, the hub 10 is provided with an annular outer wall surface 11 , an annular inner wall surface 12 , two side surfaces 13 connecting the annular inner and outer wall surfaces 11 , and a receiving hole 14 formed inside the annular inner wall surface 12 . The annular outer wall surface 11 is bonded to the polyurethane elastic bead 20 , and the a...

Abstract

The invention discloses a noise-free elevator idler wheel assembly. The noise-free elevator idler wheel assembly comprises a hub made of a nylon material of 49.0-70.0 parts by weight, a polyurethane elastic tire bead formed on the surface of the hub, and polyformaldehyde friction plates located on the two sides of the hub. The hub is provided with an annular outer wall face, an annular inner wallface and two side faces for connecting the annular inner wall face and the annular outer wall face; the two side faces of the hub are provided with grooves matched with the polyformaldehyde friction plates correspondingly; the grooves are formed in the mode of being sunken from the side faces; and each groove comprises an open groove and a clamping groove located in the inner side of the open groove. The hub is made of the nylon material of 49.0-70.0 parts by weight, the polyformaldehyde friction plates are adopted in a matched mode, a matched structure of the friction plates and the hub is improved, thus the friction plates and the hub are bonded more tightly and firmly, noise is reduced, and the polyformaldehyde friction plates are better in performance, more environmentally friendly andlower in cost.

Description

technical field [0001] The invention belongs to the technical field of elevator rollers, in particular to a noiseless elevator roller assembly. Background technique [0002] Escalators are widely used in shopping malls, supermarkets, subways and other places with a lot of passenger traffic, and as the most [0003] The roller (chain wheel), one of the important components, plays the role of driving and guiding the elevator steps. When the roller is running with a chain, the vibration of the chain will touch the side of the roller, causing the roller to wear and even cause failure. In order to solve this problem, a friction plate is usually installed on the side of the roller to protect the roller. The traditional friction plate is a phenolic resin with a high content of glass fiber with good wear resistance and self-lubricating properties. This high content of glass fiber is easy to disperse unevenly in the phenolic resin and lead to agglomeration. During lathe processing,...
