Replacement of thrust bearing with improved type CT-S-023

Mar. 7, 2012
CT-S-023 / 796-94435

REASON FOR SUGGESTION:

Recently the output demand of the turbine and compressor is increasing. So, we have developed thrust bearing for higher load.
The improvement is as follows.

  1. Direct lubrication nozzle is applied to supply necessary oil, and used oil in the bearing housing is quickly drained.
  2. Copper alloy is applied as back metal of bearing pad to improve cooling capability.
  3. Off set of the bearing pad pivot is applied to increase oil film thickness, and has improved the load ability.
  4. The shape of leveling plate was improved to reduce friction.

A sufficient improvement of the bearing metal temperature can be achieved by these modifications.


DETAILS OF SUGGESTION:

The outline of modification is as follows.

  1. When J type thrust bearing is installed, new K type bearing can be fit in the existing space because axial size is smaller than J type thrust bearing. Bearing housing is needed to be replaced.
  2. When K type thrust bearing is already used for existing, there is no need for replacing bearing housing.
    Modification of drain hole and replacement of bearing are required.
