Abstract

The invention discloses a turbine shaft connection structure of a crane. The turbine shaft connection structure comprises a turbine and a half shaft, wherein the turbine is connected with the half shaft through a rivet; and a steel flange sheet is arranged on the rivet, so that the rivet can be prevented from entering the turbine. By the turbine shaft connection structure, the technical shortcomings that the common nut for connecting the turbine and the half shaft is easy to loose, and the common bolt is easy to fall off because of frequent clockwise and anticlockwise rotation starting and braking and high impact vibration of the conventional crane in the prior art are overcome; and the turbine shaft connection structure in which the turbine and the half shaft are fixedly connected is provided.

Description

technical field [0001] The invention belongs to the field of cranes, in particular to a turbine shaft connection structure of the crane. Background technique [0002] With the development of high-power tower cranes, new requirements are put forward for the tower crane slewing transmission device: this is to reduce the number of replacements of the tower crane slewing transmission device, so as to improve the working efficiency and service time of the tower crane. This requires the normal service life of the slewing transmission device of the tower crane to be extended and the performance and quality of the slewing transmission device to be improved. [0003] In the prior art, the turbine and the half shaft of the tower-type starting and turning transmission device adopt a connection structure of ordinary countersunk bolts and spring pads to prevent loosening. Due to the frequent forward and reverse rotation, starting and braking, the impact and vibration are large, and the c...
