Abstract

The invention discloses a steam turbine generator set maintenance barring gear. The steam turbine generator set maintenance barring gear comprises a left support, a right support, a cross beam, a cycloid pin wheel speed reducer and a storage support, wherein the top of the left support and the top of the right support are correspondingly provided with fastening bolts through mounting holes, the tops of the fastening bolts are arranged at the bottom of the cross beam in a penetrating mode, the top of one side of the cross beam is provided with the cycloid pin wheel speed reducer through a firstbolt, one end of the cycloid pin wheel speed reducer is provided with a direct-connected motor, a driving gear is clamped on the periphery of a rotating shaft at the other end of the cycloidal pin wheel speed reducer, one end of the rotating shaft is provided with a shaft end retainer ring through a second bolt, the bottom of the driving gear is provided with a transition shaft in a welded mode,the periphery of the transition shaft is sleeved with a transition gear, the transition gear is in meshed connection with the driving gear, a bushing is sleeved between the transition gear and the transition shaft, and one side of the bushing is sleeved with a limiting ring. According to the steam turbine generator set maintenance barring gear, by adoption of a bridge type structure, the problemsof mounting, mounting of a base of a box body, inconvenient mounting and dismounting and the like are well solved, and meanwhile, the safety of the box body is ensured.

Description

technical field [0001] The invention belongs to the technical field of overhauling machinery for turbogenerator sets, and in particular relates to a barring for overhauling turbogenerator sets. Background technique [0002] When the general type of maintenance crank is used, there are problems of installation, installation strength of the box base, inconvenient assembly and disassembly, and the alignment of the main shaft is completely dependent on the driving, which has poor safety and relies too much on external auxiliary equipment, and cannot drive the steam wheel according to maintenance requirements Generator sets are continuous, inching, and rotate forward and reverse, so the maintenance efficiency of turbogenerator sets is low, which needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a steam turbine generator set maintenance barring, which properly solves the problems of inconvenient installation and as...
