The invention relates to a gear shaper transmission device A rack differential gear shaper transmission device comprises a crank sliding mechanism, a worm and worm gear transmission mechanism and a cutter shaft, wherein the upper end of the cutter shaft is connected with a sliding block in the crank sliding mechanism by a kinematic pair, and the lower end of the cutter shaft is fixedly provided with a gear shaper cutter The device is characterized in that: a rack assembly is fixedly arranged on the sliding block of the crank sliding mechanism, and a rack of the rack assembly is engaged witha gear of a middle transmission device; a first bevel gear of the middle transmission device is fixedly arranged on a differential main shaft of a differential transmission device; and a differentialinput wheel of the differential transmission device is connected with a worm gear driving wheel in the worm and worm gear transmission mechanism by a second driving belt or a second driving chain, a dual output driving wheel of the differential transmission device is connected with a cuter shaft driving wheel of a cutter shaft transmission mechanism, and the cutter shaft transmission mechanism isarranged on the cutter shaft The device not only can overcome the defect of easy abrasion of a spiral guide rail, but also can conveniently meet the requirement of processing bevel wheels of different spiral angles

Rack differential gear shaper transmission device

A main drive unit of a gear shaper belongs to the gear shaper parts. The main structure comprises a transmission chain mechanism, which is connected with a sliding block through a crank connecting rod. The sliding block is positioned on a linear rolling guide rail, on which a pin roller is arranged. The friction resistance between the sliding block and the guide rail is reduced, the work noise and power loss are decreased and the operational reliability of the equipment is promoted by the pin roller through the structure that the sliding block is positioned on the linear rolling guide rail.
