THE INSTALLATION OF THE SLIDING BUSHING AND THE HOUSING
The Installation of SF Bush
SF bushes should de cleaned in kerosene or diesel oil first, immersed
in engine oil and then dried up. When the bush is installed into
housing, make sure the bush not rotating in the housing or moving
in the axial direction and at the same time make the outer surface
surface fully contact to the base hole, generally guarantee the
contact area over 70%,thus to improve load capacity and transmission
of friction heat. The inner surface of SF bush is made of self-lubricating
plastic, the outer surface steel backing, The friction coefficient
of steel to steel is bigger that of steel to plastic, So we should
choose the light-graded tight fit, preventing the axle sleeve from
moving in the base when working, and also preventing the inner holes
from getting deformed and too big because of the large tight fit
of the outer diameter.
Out circle of the axle sleeve should be avoided in the high-pressure
working conditions. Two methods are recommended here:
1、Increase the outer dia meter of the axle sleeve, and the deformation
of inner holes can be calibrated with calibrating core stick.
2、When installing, apply ZY 801 Oxygen-hatred glue in the housing
to streng then the combination strength between the axle sleeve
and base hole.
For bush (outer diameter<55mm), press the bush into the housing
gently and carefully using an core axle with a handle. Fig A.
For bush (outer diameter >55mm), press the bush into the housing
gently and carefully using a handle with a shoulder, an“O”ring and
an assisting circle. Fig B.
1、Press the core axle into bushing
2、Housing chamfer at end: 0.8×15o
5、Diameter of inset shoulder
R、Radius of the round angle of the core axle end
