Method for removing and/or installing a turbine bearing and a device for carrying out the method

摘要

A method and a device are provided for removing a turbine bearing or a bearing segment of a preferably stationary turbo engine, having a housing that may preferably be split in half while the housing is closed. The method includes: supporting the rotor to relieve the turbine bearing of the weight of the rotor, fastening a support plate to a turbine bearing housing, attaching two parallel, rail-like supports to the support plate and fastening a cross-beam to ends of supports, fastening a counter-bearing plate having at least two push/pull rods to the turbine bearing housing, and fastening the push/pull rods to the turbine bearing and detaching the fastening of the turbine bearing from the turbine bearing housing and pulling the turbine bearing located in the operating position thereof out of the turbine bearing housing with the aid of the push/pull rods.

1. A method for removing or installing a turbine bearing, or one of its constituent parts, of a static turbomachine when a housing of the static turbomachine is closed, the method comprising:
a) supporting a rotor and/or holding the rotor in order to free the turbine bearing from the weight of the rotor, b) fastening a support plate to an end face of a turbine bearing housing, attaching to the support plate two mutually parallel rail-like beams so that the beams extend into and out of the turbine bearing housing, and fastening a cross beam to those ends of the beams which are opposite the support plate, c) positioning the turbine bearing on the beams so that the beams act as a cantilevered support under the turbine bearing, and d) moving the turbine bearing on the beams from a first position to a second position.
