Gear broaching process for thin-wall internal spline shaft

Abstract

The invention discloses a gear broaching process for a thin-wall internal spline shaft, and relates to the technical field of internal spline shaft machining. The gear broaching process specifically comprises the following steps that S1, firstly, a round steel material is selected for blanking, and the round steel material is cut into the size required by an internal spline shaft through cutting equipment according to the required workpiece size to form a workblank; and S2, rough turning is carried out on the workpiece, the cut workblank is polished through polishing equipment, after polishingis completed, the workpiece is clamped through a clamp, then rough machining is carried out on an inner hole, an outer circle and the length of the workpiece through a horizontal lathe, so that the workpiece is made to be close to the final shape and size, and 0.4mm - 1mm machining allowance is correspondingly reserved for the inner hole, the outer circle and the length of the workpiece after rough turning. According to the gear broaching process for the thin-wall internal spline shaft, the gear broaching process is adopted to replace a gear shaping process to machine an internal spline, theproduct machining precision is improved, the product quality is stabler, the product damage rate is reduced, the economic loss is reduced, and the loss of a cutter is small.

Description

technical field [0001] The invention relates to the technical field of internal spline shaft processing, in particular to a thin-walled internal spline shaft broaching process. Background technique [0002] The spline shaft is a kind of mechanical transmission, and the flat key, half-round key, and oblique key have the same function, and they all transmit mechanical torque. There are longitudinal key grooves on the outer surface of the shaft, and the rotating parts on the shaft also have corresponding key grooves. It rotates synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc. The spline shaft is divided into two types: rectangular spline shaft and involute spline shaft. The rectangular spline shaft in the shaft is widely used, while the involute spline shaft is used for large loads, high centering accuracy requirements, and large-scale connections. Rectangular spline shafts are usually used in aircr...
