Problems solved by technology

[0004] The existing rotary reducer 1a is connected to the rotary support 4a through 24 bolts. Therefore, when adjusting the backlash by rotating the rotary reducer 1a, there are only 12 positions to choose from. The adjustment unit has a large span and a small adjustment range. Make adjustment accuracy poor

Abstract

The invention discloses a slewing mechanism, a tooth side clearance adjustment method and a crane. The slewing mechanism includes a reducer, a slewing support and a slewing support; the slewing support has a mounting hole for sheathing and installing the reducer; the slewing support and the reducer housing are matched by splines, and the center lines of the splines are opposite It is arranged eccentrically on the center line of the transmission shaft of the reducer; and the slewing bearing is meshed with the gear of the output shaft of the reducer. The slewing mechanism of the present invention uses splines to connect the reducer and the slewing support. During the adjustment process of the tooth side clearance, the adjustment is performed in units of a single spline. Because the number of teeth of the splines is dense and evenly distributed, the tooth side clearance adjustment of the present invention Wider range, better continuity and higher precision.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a slewing mechanism, a tooth side clearance adjustment method and a crane. Background technique [0002] Such as figure 1 As shown, the slewing mechanism in the prior art includes a slewing reducer 1a, a slewing support 4a, a slewing support 5a, a turntable support and a hydraulic device. The rotary reducer 1a is fixed on the rotary support 4a through the bolt group 3a, and the rotary support 5a is gear-engaged with the rotary reducer 1a. Wherein, the installation centerline A of the rotary reducer 1a is eccentrically set relative to the drive shaft centerline B of the rotary reducer 1a and the center distance between the above two centerlines is S1, the drive shaft centerline B of the rotary reducer 1a and The center distance between the centerlines C of the slewing bearings is S2. The hydraulic device provides power, and the slewing reducer 1a and slewing bear...
