Water pump bearing factory tutor you how to determine axial clearance of the bearing bearings mounted on the shaft or set set of clearance in determination of bearing outer ring price roller sagging state of clearance.
First, ensure the integrity of the bearing outer ring 1/2 - gesture to turn right or left
1, 2 column roller column of any roller was positively at the bottom of the location, respectively.
Determination of using feeler clearance, somewhat different parts according to the bearing outer ring outside diameter size.
Outer diameter greater than 200 mm of bearing clearance measurement insert the pin into the bearing is between the above 2 column roller and outer ring and the relative position of bearing center symmetric 2 columns between roller and inner circle, the determination of the bearing internal clearance.
Bearing internal clearance is r, the bearings are the following two columns between rollers and the outer ring of bearing internal clearance respectively set to rS1 ` rS2, internal clearance on bearing is set to rS.
rS=1/2(
rS1+rS2)
The relative position of bearing center symmetric 2 columns between rollers and the outer ring of bearing internal clearance and 2 column on the left side of determination of clearance between roller and outer ring, respectively, set to rL1 ` rL2, set on the left side of the bearing internal clearance to rL.
rL=1/2(
rL1+rL2)
Between the two columns on the right side of the roller and outer determination of the clearance is set respectively for R1 ` rR2, on the right side of the bearing internal clearance is set for the rR.
rR=1/2(
R1+R2)
Use the type bearing internal clearance.
r=1/2(
rS + rL + rR)
