Problems solved by technology

However, for large shaft parts, most of the current repair methods are manual repair, or simple grinding wheel mechanism for repair, which is difficult to meet the precision and surface roughness requirements, and there are still potential safety hazards even after the repair is completed.

Abstract

The invention provides a large shaft type part journal grinding apparatus and a grinding process. The large shaft type part journal grinding apparatus comprises a grinding component, a power mechanism and a revolving mechanism clamped to a large shaft type part. The revolving mechanism comprises two clamping members which are spaced axially. The grinding component is mounted between the two clamping members detachably. The two clamping members are provided with coaxial central holes through which the large shaft type part can penetrate. Each clamping member is provided with a locating component connected with the large shaft type part in an oriented manner. Each clamping member is connected with the power mechanism via transmission component. Under the drive of the power mechanism, the two clamping members rotate around the large shaft type part synchronously, so that the grinding component can perform grinding repair on a journal of the large shaft type part. The feed and the back engagement of the grinding component can be controlled and the grinding precision can be adjusted to achieve designed surface roughness.

Description

technical field [0001] The invention relates to a technology for repairing damage to shaft parts, in particular to a grinding equipment and a grinding process for journals of large shaft parts. Background technique [0002] With the development of industry, the size of large shaft parts (such as steam turbine and generator rotors, marine crankshafts, etc.) is getting larger and better, and the materials are getting better and better, so the requirements for the journal part as its support are also increasing. High, specifically in the following aspects: high-precision shape tolerances (straightness, roundness, cylindricity, concentricity or outer circle runout, full runout), high-precision dimensional tolerances, high-demand surface roughness ( Generally Ra0.2~Ra0.8). [0003] As the support of the slewing system, the journal is prone to wear, roughening, marks, etc., causing system instability and seriously affecting operation safety. Such large shaft parts are key compon...
