Gear-shaving machine

Abstract

The invention relates to a gear-shaving machine. The gear-shaving machine comprises a lathe bed, a feeding device, a spindle box and a clamp. The clamp is used for clamping a workpiece, a spindle is rotationally arranged in the spindle box, and the spindle is used for allowing a gear shaving cutter to be mounted and driving the gear shaving cutter to rotate. The feeding device is used for drivingthe spindle box to move in the radial direction of the workpiece. A positioning gear and a transmission mechanism are further included, the positioning gear is rotationally arranged on the lathe bed and located on one side of the clamp, and the positioning gear is used for engaging the workpiece. The transmission mechanism is arranged between the spindle and the positioning gear, so that the positioning gear rotates synchronously along with the spindle, and the linear velocity of the positioning gear is equal to that of the gear shaving cutter. The gear-shaving machine has the advantages thatmounting and positioning of a workpiece are completed at the same time, moving of the gear shaving cutter is achieved at one step, the gear shaving cutter does not need to be driven to be close to theworkpiece twice, and the production steps can be simplified, so that the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of gear shaving, in particular to a gear shaving machine. Background technique [0002] A gear is a mechanical element with teeth on the rim that can be continuously meshed to transmit motion and power. [0003] Shaving machining is used for the finishing of unhardened gears and has the following three movements: [0004] 1. The gear shaving cutter drives the high-speed forward and reverse motion of the workpiece - the basic motion; [0005] 2. Reciprocating motion along the axial direction of the workpiece - to process the full tooth width of the gear; [0006] 3. Feed movement along the radial direction of the workpiece - to cut off all the allowance. [0007] In view of the above-mentioned related technologies, the inventor believes that after the workpiece is installed on the gear shaving machine, in order to ensure that the gear shaving cutter meshes with the workpiece, it is necessary to first drive...

AI Technical Summary

Problems solved by technology

[0007] In view of the related technologies mentioned above, the inventor believes that after the workpiece is installed on the gear shaving machine, in order to ensure that the gear shaving cutter meshes with the workpiece, it is necessary to first drive the gear shaving cutter close to the outer circumference of the workpiece, and then fine-tune the circumference of the workpiece or the gear shaving cutter. To the position, after that, drive the shaving cutter again to approach and engage the workpiece to start the shaving process, resulting in the defect of low production efficiency
