Problems solved by technology

[0005] When the test bearing pad (15) is in operation, there is no sealing pad (11) on the inner side of the machine, but it is directly adjacent to the inner test oil retaining cap (12), so since the test bearing pad (15) itself does not have an oil retaining structure, Just make the oil leakage phenomenon often take place on the inner side of the bearing during the test, even if the installation requirements of the test oil retaining cap (12) are improved, this problem cannot be solved

Abstract

The invention relates to an inside oil baffle structure of a bearing bush machine for the dynamic balance test of a rotor of a large turbo-type generator, which comprises a drain pan and an oil baffle table at the inner side of the bearing bush machine, a tungsten structure on the surfaces of the drain pan and the oil baffle table, a small oil baffle cover assembled at the inner side of the bearing bush machine for test, a copper comb embedded into the small oil baffle cover and a structure of spigot positioned between the small oil baffle cover and the bearing bush for test. In the invention, the application of the oil baffle structure of the bearing bush for test reduces the installation requirement of the bearing for test than before, and the effect of oil baffling is enhanced obviously than before without oil leakage not for a moment.

Description

Technical field: [0001] The invention relates to an oil retaining structure on the inner side of a test bearing pad machine for dynamic balancing of a large steam turbine generator rotor. technical background: [0002] A test bearing is required during dynamic balancing of a large steam turbine generator rotor, which includes a test bearing seat (13), a test bearing bush (15), and a test oil retaining cover (12). The function of the test oil retaining cap (12) in the test bearing is to prevent the bearing lubricating oil formed in the oil film between the test bearing pad bearing surface (10) and the main shaft (14) from leaking to the outside of the bearing, but the oil retaining structure in the test bearing pad (15) The design also plays a considerable role in preventing the leakage of lubricating oil. [0003] In the past, the test bearing pad (15) used for dynamic balancing of large turbogenerators had the same structure and size as the product bearing pad (16). The s...
