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