A matching research method for the spherical contact surface of the generator bearing seat and the bearing bush

Abstract

The present invention discloses a generator bearing and bearing bush ball-type contact surface running-in method. The method comprises the steps of: installing and lifting a bearing bush; respectivelyusing two developers with different colors onto the bearing bush and a bearing pedestal to allow a display effect after grinding to be clearer, coating the first-type developer at an inner ball surface of the lower half portion of the bearing pedestal, and coating the second-type developer on an outer ball surface of the bearing bush; determining a grinding amplitude; and comparing developing areas of the two developers on the bearing pedestal, and determining whether the running-in of the two is qualified or not according to qualification requirements defined in advance. The generator bearing and bearing bush ball-type contact surface running-in method makes corresponding standards for each link of the running-in process consisting of installation of the bearing bush, lifting of the bearing bush, the grinding amplitude, the color coating method and the qualification determination so as to improve the contact surface of the bearing bush and the bearing pedestal and improve the bearingsealing, the operation stability and the production efficiency.

Description

technical field [0001] The invention relates to a matching research method for a spherical contact surface of a generator bearing seat and a bearing bush, and belongs to the technical field of generator bearing seal manufacturing. Background technique [0002] The bearing pad is the main support for the rotor, and the quality of the contact surface between the bearing pad and the bearing seat directly affects the vibration of the turbine generator rotor and the heating of the bearing pad. The traditional process is to carry out matching research with the bearing seat after the bearing bush is completed. This traditional process has great uncontrollability, and there is no national standard support. The effects of multiple matching researches are different, which restricts the production of turbo-generators in many ways: 1. Low production efficiency: the effect of each matching research is different, which makes the matching research cycle longer; 2. Affects product quality: ...

The effects of multiple matching researches are different, which restricts the production of turbo-generators in many ways: 1. Low production efficiency: the effect of each matching research is different, which makes the matching research cycle longer; 2. Affects product quality: every time After each installation, it will be different from the original grinding effect, which will reduce the contact surface and affect the stability of the product; 3. Serious labor waste: due to the different grinding methods and effects, each grinding will cause a long time waiting for work, and produce Multiple rework and duplication of labor
