Automatic gap elimination type worm wheel and worm structure as well as machining method and gap elimination method thereof

Abstract

The invention discloses an automatic gap elimination type worm wheel and worm structure as well as a machining method and a gap elimination method thereof. The automatic gap elimination type worm wheel and worm structure comprises a worm wheel and a worm, the worm wheel and the worm cooperate with each other, the worm comprises a worm shaft, a worm sleeve, a spring, a compression nut and a lockingnut, the worm shaft is connected with the worm sleeve through a spline, and one end of the worm shaft and one end of the worm sleeve are fixed through the compression nut and the locking nut. According to the automatic gap elimination type worm wheel and worm structure as well as the machining method and the gap elimination method thereof, for the automatic gap elimination type worm, machining issimple, the automatic gap elimination effect can be achieved without manual adjustment in the assembling process, the rotating precision of rotating equipment can be guaranteed all the time, maintenance-free effect on the worm wheel and the worm can be achieved only through one-time assembling, so that the service lives of the worm wheel and worm are greatly prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to an automatic backlash-eliminating worm gear structure, a processing method thereof, and a backlash-eliminating method. Background technique [0002] Worm gear transmission is a common mechanical transmission structure. The helical teeth of the worm are inserted into the helical teeth of the worm gear, and the rotation of the worm drives the worm gear to rotate. Due to errors in processing and wear during use, worm gears There will definitely be gaps in between. At present, variable lead worms are mainly used to eliminate the gap between worm gears and worms. Due to the high difficulty of processing variable lead worms, and the need for professionals to adjust the thickness of the worm gasket many times during the first assembly, the effect of eliminating the gap can be achieved. During use, there will be a gap between the worn worm wheel and the worm, and the gap...

Problems solved by technology

At present, variable lead worms are mainly used to eliminate the gap between worm gears and worms. Due to the high difficulty of processing variable lead worms, and the need for professionals to adjust the thickness of the worm gasket many times during the first assembly, the effect of eliminating the gap can be achieved. During use, there will be a gap between the worn worm gear and the worm again, and the gap will become larger and the accuracy will be worse, which will seriously affect the accuracy of the processed workpiece.

Therefore, the variable lead worm must be regularly maintained by professionals to adjust the cooperation between the worm and worm gear, which greatly reduces the production efficiency and increases the cost of use.
