Pull and support design solid bearings and split bearings are fiction
bearings
You can remove bearing cups from a housing using a cup puller
(inside puller) provided that?
a. it is a tapered roller bearing
b. it is an anto froction bearing
c. it is a bearing on a positive set
d. the jaws can be inserted behind the shoulder -ANSWER-d. the jaws
can be inserted behind the shoulder
Main difference between adapter sleeve and withdrawal sleeve? -
ANSWER-withdrawal sleeve used on solid bored blousing and
adapter sleeve used on split bored housing
A replacement bearing such a s tapered roller or angular contact
bearing has it end float controlled by?
a. collar
b. shaft shoulder
c. chamfer
d. shims -ANSWER-d. shims
,When installing a hot bearing on a shaft move it __________ into its
final position.
a. slowly
b. in a rolling fashion
c. clockwise
d. quickly -ANSWER-d. quickly
When mounting spherical roller bearings the first step is to?
a. check the reduction is radial clearance of the bearing to ensure
proper installed clearance exists
b. check the reduction is radial clearance of the bearing to ensure
proper installed clearance exists
c. The outer face of the sleeve needs to be tapered
d. check the initial clearance by inserting a feeler gauge between top
rollers and outer ring
e. check the initial clearance by inserting a feeler gauge between top
rollers and inner ring -ANSWER-d. check the initial clearance by
inserting a feeler gauge between top rollers and outer ring
Mounted tapered Bore bearings using hydraulic nut--check the
reduction is radial clearance of the bearing to ensure proper installed
clearance exists
Ball bearings using tapered SLEEVE--check the reduction is radial
clearance of the bearing to ensure proper installed clearance exists
The use of a tapered adapter sleeve allows you to?
a. rotate at higher speeds
b. rotate at higher velocity
c. increase end play
d. mount a bearing anywhere on a standard shaft -ANSWER-d. mount
a bearing anywhere on a standard shaft
Thrust control can be obtained by using a single taper roller bearing or
a singular contact bearing on one end and?
a. adjusting shrink
b. using matched duplex on other end of shaft
, c. allowing other end to float
d. allowing other end to travel -ANSWER-c. allowing other end to float
Thrust adjustment for angular contact or tapered bearings are made in
two ways.
1. adjust inner race or cone when the outer race or cup is fixed in the
housing
2. adjust snap ring and end play
3. adjust outer race or cup when the inner race or cone id fixed on the
shaft
4. locate bearing stabilizer and adjust face plate
a. 1,2
b. 2,3
c. 1,3
d. 2,4 -ANSWER-c. 1,3
In most cases the outer race is adjusted by means of an end cover or
shims
Adding shims increases end float
removing shims decreases end float
How do you prevent end float in fixed bearings?
a. only one bearing on any shaft assembly should be fixed axially in
the housing
b. both bearings on any shaft assembly should be fixed axially in the
housing
c. install with shrink fit
d. install with press fit -ANSWER-a. only one bearing on any shaft
assembly should be fixed axially in the housing.
Generally better to "held" or fix bearing on drive end and all other
bearings should have axial clearance to allow movement. This allows
for expansion and contraction (free or floating bearings)
