Description

Worm wheel processing trimming device Technical Field The utility model relates to the technical field of worm gear machining equipment, in particular to a worm gear machining and trimming device. Background In a machine-type enterprise, a large number of production facilities are required, which generally consist of a power section, a transmission section, a control section and a work section, and the most common mechanical transmission mechanisms in the transmission section are gear transmission, belt transmission, chain transmission and worm gear transmission. Worm drive is widely accepted in some mechanical equipment, and is equivalent to screw drive, so that the worm drive is a multi-tooth meshing drive, stable in drive, low in noise, self-locking and suitable for being used in a speed reducer. But has lower transmission efficiency and serious abrasion, and has large friction loss and low efficiency due to large relative sliding speed between meshing wheel teeth when the worm gear is meshed for transmission, and has serious abrasion and serious heating of tooth surfaces due to large relative sliding speed on the other hand. Therefore, the worm wheel is extremely serious in loss, some perfect worm wheel spare parts are required to be prepared for time, the worn worm wheel after replacement is sent to a manufacturer for maintenance, in actual operation, some worm wheels may lack spare parts or have high maintenance cost, for example, some tooth surfaces are slightly deformed and also need to be sent back to the manufacturer, loss of time and logistics cost is greatly caused, and some worn worm wheels are sent back to the manufacturer, the situation that the worm wheel cannot be maintained and directly scrapped may occur, but the scrapped worm wheels can be completely reprocessed into worm wheels with smaller sizes for recycling, material cost is reduced, but maintenance manufacturers generally directly send back to new worm wheels, and the problem of increase of enterprise cost is caused, so that a device capable of repairing and processing the worm wheels is needed to reduce the production cost of enterprises.
