Description

Single power source double-worm driven slewing drive unit
Technical field
The utility model relates to a kind of device for revolving and driving, specifically relates to a kind of single power source double-worm driven slewing drive unit, is widely used in and needs upper and lower two-part various driving mechanism in relative rotation, particularly heavy duty transmission system.
Background technique
At present, because device for revolving and driving is integrated with pivoting support and worm gear structure, axial force, radial force and tilting moment can be born simultaneously, thus in the industries such as engineering machinery, harbour machinery, mining machinery, extensive application is had, two kinds of forms are had at present: one is single worm drive in worm drive, namely only arrange a worm screw in the outside of pivoting support, can only be used for transmitting less torque occasion; Another kind is double worm, and be namely arranged in parallel in the both sides of pivoting support two worm screws, drives two worm screws respectively with two motors, driving pivoting support rotates, and can be used for transmitting comparatively high pulling torque occasion, shortcoming is: (1) needs two motor drivens, structural portion is compact, and cost is high; (2) synchronism is bad, and transmission is not steady.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of single power source double-worm driven slewing drive unit, its compact structure, cost is low, stable drive.
The purpose of this utility model is achieved in that a kind of single power source double-worm driven slewing drive unit, it comprises pedestal, described pedestal comprises seat ring, first axle housing and the second axle housing, described first axle housing and the second axle housing lay respectively at the seat ring left and right sides, the center line of described first axle housing and the non-parallel layout of center line of the second axle housing, pivoting support is provided with in described seat ring, the first worm screw is provided with in described first axle housing, the second worm screw is provided with in described second axle housing, described first worm screw and the second worm screw are meshed with pivoting support outer ring respectively, described first worm screw lower end is provided with the first worm gear, described second worm screw lower end is provided with the second worm gear, the 3rd worm screw is provided with between described first worm gear and the second worm gear, described 3rd worm screw is meshed with the first worm gear and the second worm gear respectively, described 3rd worm screw outer end is connected with motor.
Compared with prior art, the utility model has following beneficial effect:
A kind of single power source double-worm driven slewing of the utility model drive unit, it is by a motor driving two worm screws, and its compact structure, cost of production is low, and synchronism is good, stable drive, can be used in the occasion transmitting larger torque.
