Abstract
A roller for an elevator system has a roller body made of a metal material and a shell made of a POM material forming a running surface of the elevator roller. The shell and the roller body each have a wave profile running in a circumferential direction on a shared contact surface, wherein the shell has, on the running surface, a V-ribbed profile aligned with the wave profile of the roller body that has a rib spacing which substantially corresponds to a wave spacing of the wave profile. The elevator roller is manufactured using a molding process.

An elevator roller for an elevator system, the elevator roller comprising:
- a roller body made of a metal material;
- a shell made of a POM material and forming a running surface ending in a circumferential direction about an outer surface of the elevator roller;
- wherein the shell and the roller body each have a wave profile running in the circumferential direction on a shared contact surface;
- and
- wherein the shell has, on the running surface, a V-ribbed profile aligned with the wave profile of the roller body, the V-ribbed profile having a rib spacing that corresponds to a wave spacing of the wave profile of the roller body, where a groove between each rib of the V-ribbed profile of the shell aligns radially with a valley of the wave profile of the roller body, where the groove and the valley each correspond with a location of locally minimum radius from an axis of rotation of the elevator roller.
A method for manufacturing an elevator roller for an elevator system, the method comprising the steps of:
- forming a shell of a POM material with a running surface;
- connecting the shell to a roller body made of a metal material at a common contact surface to form the elevator roller;
- wherein the contact surface has a wave profile running in a circumferential direction of the elevator roller;
- and
- wherein the shell has a V-ribbed profile running in the circumferential direction on the running surface, the V-ribbed profile having ribs at a rib spacing corresponding to a wave spacing of the wave profile, where a groove between each rib of the V-ribbed profile of the shell aligns radially with a valley of the wave profile of the roller body, where the groove and the valley each correspond with a location of locally minimum radius from an axis of rotation of the elevator roller.
