Abstract
The utility model relates to the technical field of worm gears and worms and discloses a worm gear and worm clearance adjustment structure, which comprises a shell, wherein a worm gear and a worm which are meshed with each other are arranged in the shell, a bearing is arranged at the end part of the worm, a sheath is arranged outside the bearing, the sheath is clamped in the shell, a connecting hole is formed in the sheath and is communicated with a space on one side of the bearing, a conical screw is connected in the connecting hole in a threaded manner, and the conical screw abuts against the bearing. The utility model is convenient for adjusting the gap between the worm gear and the worm.
Description
Technical Field
The utility model relates to the technical field of worm gears, in particular to a worm gear clearance adjustment structure.
Background
When the vehicle normally runs, alternating external force applied by the road surface can be timely transmitted to parts such as a steering knuckle and a tie rod, and then the parts are transmitted to a worm gear reduction transmission mechanism, the tooth surfaces of the worm gears and the worm gears which are meshed with each other are worn, gaps are formed between the meshing tooth surfaces of the worm gears and the worm gears which are relatively fixed by the rotary shaft core, the existence of the gaps provides the opportunity of tooth surface impact vibration for the alternating external force applied by the road surface and transmitted to the worm gear reduction transmission mechanism through the parts such as the steering knuckle and the tie rod, on one hand, the impact vibration can further damage the worm gear reduction transmission mechanism, and on the other hand, vibration noise can be generated. Meanwhile, during design, machining deviation of the worm gear and the worm gear can occur inevitably, and the problem that the consistency of idle rotation moment of the worm gear and the worm gear is poor due to machining deviation of the installation size of the shell, assembly deviation and the like. There is a need for a worm gear structure that can adjust the gap between the worm gears, thereby solving the above-mentioned problems.
Disclosure of utility model
The utility model aims to provide a worm gear clearance adjustment structure which has the effect of conveniently adjusting the clearance between worm gears.
The technical aim of the utility model is realized by the following technical scheme: the utility model provides a worm gear clearance adjustment structure, includes the casing, the inside worm wheel and the worm that is provided with intermeshing of casing, the tip of worm is provided with the bearing, the bearing outside is provided with the sheath, the sheath card is established inside the casing, be provided with the connecting hole on the sheath, the space intercommunication of connecting hole and bearing one side is provided with the conical screw in the connecting hole, the conical screw offsets with the bearing.
The beneficial effects of the utility model are as follows:
Through simple conical screw and sheath integrated configuration, easy-to-operate's worm gear clearance adjusting device for adjust worm gear center distance, reduce the noise of product, promote driver's driving experience.
