Abstract

The hobbing cutter fixed type gear forming machining platform comprises a rack, a workpiece support, a cutter rest used for installing a hobbing cutter, a variable speed toothed belt and a gear pump, the variable speed toothed belt is in transmission through a fixed wheel disc and a movable wheel disc, the fixed wheel disc is fixedly connected to a fixed shaft in a sleeving mode, and the fixed shaft is connected with a synchronous rod through a synchronous belt; the synchronous rod is fixedly connected to the knife rest; the movable wheel disc is fixedly connected to a movable shaft in a sleeving mode, the movable shaft is fixedly connected with a gear shaft of a gear pump, and the gear pump is driven to supply oil to a hydraulic motor driving a workpiece to rotate. A stable power transmission relation can be formed between the workpiece and the hobbing cutter of the hobbing cutter fixed type gear forming machining platform, and the forming machining precision of a gear is high; the speed change gear belt increases the applicability of the whole gear forming machining platform, stable speed change and power transmission can be kept, meanwhile, it is guaranteed that hydraulic pressure is stable, and the machining quality of the whole system is stable.

Description

technical field

[0001] The invention relates to the technical field of gear processing, in particular to a hob fixed gear forming processing platform. Background technique

[0002] The hobbing gear can be regarded as a gear and rack transmission without meshing backlash. When the hob rotates one revolution, it is equivalent to the rack moving one tooth in the normal direction. The continuous transmission of the hob is like an infinitely long rack moving continuously. When the hob and the hob blank are forced to mesh and drive in strict accordance with the transmission ratio of the gear to the rack, the envelope of the hob teeth at a series of positions forms the involute tooth profile of the workpiece. With the vertical feed of the hob, the required involute tooth profile can be hobbed and cut. In order to obtain the involute tooth profile and the number of gear teeth, a strict relative motion relationship must be maintained between the hob and the workpiece during gear ho...
