Embodiment 2
[0034]Example 2 is basically the same as Example 1, the difference is that the contact time between two adjacent strands of viscous liquid wheel frame materials is controlled within 10 seconds, the temperature is 275°C and the pressure is 130MPa until the weld line of the two strands is two The ends are fully fused.
Embodiment 3
[0036] Example 3 is basically the same as Example 1, the difference is that the contact time between two adjacent viscous liquid wheel frame materials is controlled within 7 seconds, the temperature is 277°C and the pressure is 100 MPa until the weld line of the two materials is two The ends are fully fused.

The invention provides a method for manufacturing an escalator roller, which belongs to the technical field of escalator rollers and solves the problems that an escalator roller is manufactured by means of mounting a bearing injection molding wheel carrier and then forming an outer ring in an injection molding manner in the prior art, adhesion is unsatisfactory generally, or assembly efficiency is low, assembly difficulty is high and the like. The method for manufacturing the escalator roller includes the steps: A, forming an outer ring in an injection molding manner through an outer ring mould; and B, forming the roller by respectively placing a bearing and the outer ring into a wheel carrier cavity in a wheel carrier mould, performing injection molding in the wheel carrier cavity between the bearing and the outer ring and stripping the mould to obtain an escalator roller blank. By the aid of the method for manufacturing the escalator roller, components do not need to be assembled, firmness of adhesion of the wheel carrier and the outer ring is improved, reliability of matching of the bearing and the wheel carrier is enhanced, and production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a method for manufacturing a roller of an escalator. Background technique [0002] The escalator has the advantages of stable operation, low noise, and durability, and is suitable for shopping malls, supermarkets, subways, airports and other places with a large passenger flow, and the roller is a relatively important part of the escalator. The roller includes a bearing and a wheel frame. The wheel frame is generally made of alloy material alone, and then the wheel frame is sleeved on the outer ring of the bearing. In order to increase the wear resistance of the outer circle of the wheel frame, an outer ring made of rubber or other materials is generally set on the wheel frame. [0003] The rollers installed on the escalator can be divided into front rollers and rear rollers. In practical applications, the performance requirements for the rollers are relatively high. Each roller m...
