The bearing
installation has close relationships with the accuracy,
life and performance. Therefore the design and assembly
departments should fully research into the bearing installation.
It is better to implement installation according to
the operation standard. The items of the operation standard
are usually as follows:
(1)
Clean bearing and its related parts
(2)
Check the size and finishing conditions of the related
parts
(3)
Installation
(4)
Examine bearings after installation
(5)
Feed the lubricant
The bearing packing should be opened shortly before
installation. There is no need for cleaning to ordinary
lubricating grease lubrication, direct-filling of lubricating
grease or lubricating oil. Whereas it should use the
clean oil to rinse the instrument purpose bearing or
high speed purpose bearing etc. and get rid of the anti-rusting
agent on the bearing. The bearing easily gets rusty
without rust inhibitor. Therefore special care should
be taken to such kind of the bearing.
What is more, the bearing which has been sealed with
lubricating grease can be put into direct use with no
cleaning at all.
The installation methods of the bearing vary according
to the difference in the bearing structure, matching,
condition. As it is mostly of axle rotation, the inner
ring needs interference fit. The cylindrical bore bearing
is commonly pressed in by pressing machine or most probably,
it adopts the heat installation method. The taper hole
can be directly
installed in the taper axle or by sleeving.
When it has been mounted to outer casing, usually
it has excess clearance fit, the outer ring has shrink
range, it will be pressed in |
