Problems solved by technology

[0003] The object of the present invention is to address the above problems, to provide a crane slewing mechanism with adjustable gear clearance, to solve the problem that the gap between the driving gear of the slewing mechanism of the existing crane and the outer ring gear of the slewing support cannot be adjusted. In the middle, the meshing gap will become larger and larger, resulting in the problem of poor transmission accuracy

Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0014] Please refer to figure 1 and figure 2 As shown, in this embodiment, a crane slewing mechanism with adjustable gear clearance includes a motor 1, a reducer 2 and a slewing support 7 fixed on a base 5, and the output end of the motor 1 is connected to the reducer 2 , the reducer 2 is detachably installed on the base 4 through the flange 3, and the output shaft of the reducer 2 is keyed with a drive gear 6, and the drive gear 6 is meshed with the outer ring gear of the slewing bearing 7 , and the driving gear 6 and the flange 3 are eccentric structures.

[0015] When it is necessary to adjust the meshing gap, remove the mounting bolts on the flange 3 and turn the flange 3 before installing, then the meshing gap between the driving gear 6 and the outer ring gear of the slewing bearing 7 can be...

Abstract

The invention discloses a crane slewing mechanism capable of adjusting a gap between gears. The crane slewing mechanism comprises a motor, a reducer and a slewing bearing fixed on a base, wherein an output end of the motor is connected with the reducer, the reducer is detachably arranged on a base seat through a flange, an output shaft of the reducer is fixedly connected with a gear which is meshed with an outer gear ring of the slewing bearing, and the gear and the flange are in a eccentric structure. The crane slewing mechanism capable of adjusting the gaps between the gears is simple in structure and easy to realize. Due to the fact that the gear and the flange are in the eccentric structure, when a central distance needs adjusting, the meshing gap between the drive gear and the outer gear ring of the slewing bearing can be changed as long as the flange is rotated, and therefore the meshing gap can be adjusted conveniently.

Description

technical field [0001] The invention relates to a gear gap adjusting device, in particular to a crane slewing mechanism capable of adjusting the gear gap. Background technique [0002] Cranes mainly include hoisting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure. The slewing mechanism is used to turn the arm frame, and it is composed of a driving device and a slewing bearing. In the existing slewing mechanism of cranes, the gap between the outer ring gear of the slewing ring and the driving gear cannot be adjusted, and the driving gear and the outer ring gear of the slewing ring are constantly moving and rubbing, the meshing gap will become larger and the transmission accuracy will also be improved. worse. Contents of the invention [0003] The object of the present invention is to address the above problems, to provide a crane slewing mechanism with adjustable gear clearance, to solve the problem that the gap between the driving...
