Escalator friction wheel

Escalatorfriction wheels is a part of escalator, and it’s quick-wear part, this article will help you know escalator fricion wheel.


Technology
Escalatorfriction wheels consist of an elastomer coating and a metal body.
The elastomer coating is like the escalator handrail’s coating.
The friction lining is permanently joined to the metal part.
The polychloroprene based elastomer mixture used has a hardness of 80 ± 5 Shore A. It is wear resistant and largely oil resistant, by the way Escalator firction wheel also using ellow paint to rust-proof.
The metal body is made from standard free cutting  steel 9 S 20 K. Centerings are provided for subsequent machining.
The metal body is wider on one side than the friction lining for easy rolling gear mounting.

Installation
The axles of the driving and driven shafts must be aligned parallel. Radial runout of the wheels must be avoided.
Where rolling gears are mounted side by side, the shaft must have sufficient rigidity.
For applications requiring a virtually vibration-free drive and high concentricity – and rolling gears mounted in pairs – the rolling gears must ground after mounting.
Worn rolling gears must be replaced in pairs.
In this way,the high production tolerances are compensated and rolling gears mounted in pairs are subjected to uniform load.

matters need attention
When machining the metal parts, the temperature of the metal should not exceed 100 °C. When grinding and turning, the temperature of the friction lining should not exceed 70 °C, briefly 80 °C.
Reciprocating longitudinal grinding produces a smooth surface.
Face grinding must be avoided.
Exerting low pressure prevents excessive heating. The elastomer coating smears under excessive pressure.
If the surface is smeary, interrupt grinding and allow the elastomer coating to cool down completely.
Apply talcum powder to the surface.

Subsequently grind clean exerting low pressure.
In normal the thickness of escalator friction wheel is 5-7mm, and i can working over more than 12months, our escalator friction wheel's thickness can be 9-10mm, so ours can working over more than 24months.

So pls contact us if you interested in escalator friction wheel, and you can buy escalator friction wheel from alibab
