Device for air cooling island and being convenient to assemble and preventing gear shaft from being collided and damaged

Abstract

The invention provides a device for an air cooling island and being convenient to assemble and preventing a gear shaft from being collided and damaged. The device comprises a tool sleeve and a hole clamping spring, the tool sleeve is in a bearing shape, the outer circle diameter and the inner circle diameter of the tool sleeve are consistent with the bearing, the bottom of the tool sleeve is provided with a plurality of hosting holes, and the hole clamping spring is arranged between the side, provided with the hoisting holes, of the tool sleeve and the inner wall of a reduction gearbox body. After the bearing at the upper end is installed, the tool sleeve and the clamping spring are installed, so that the shaft is fixed on the gearbox body to replace a bearing at the lower end, then the gearbox body is turned over, the gear shaft is fixed relatively, and collision and damage of the gear surface cannot be generated, and the effect of safety protection is achieved.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a device for an air-cooled island that facilitates assembly and prevents gear shafts from colliding and damaging. Background technique [0002] The special reducer for the air-cooled island adopts a vertical downward output shaft structure, and the integral casting box has a compact structure. When installing the internal gear shaft, gear, bearing and ring kit, the box needs to be turned over several times. The general installation steps are: first install The output shaft and the low-speed gear, the low-speed gear is installed after the output shaft, and then the gear shaft and the gear are installed. Before installing the gear shaft, the gear needs to be put into the box, and the gear shaft is interference-fitted into the gear on the press. After the gear is installed on the gear shaft, install the bearing at the upper end, and finally install the bearing at the lower end of t...

AI Technical Summary

Problems solved by technology

After the upper bearing is installed, it is necessary to turn the case over 180° before installing the lower bearing. Since the lower bearing is not installed, the axial direction of the gear shaft is not positioned. In addition, the type of the upper bearing is a tapered bearing with separate inner and outer rings. When the box is overturned, the axial direction of the gear shaft and the gear can move freely. When the movement occurs, the gear shaft teeth and the low-speed gear teeth will inevitably collide and collide, which will cause serious damage to the meshing tooth surfaces. damage
