Problems solved by technology

Due to the double-sided meshing, both sides of the shaving cutter can be cut, but because the cutting angles of the two sides are different, one side is an acute angle, and the cutting ability is strong; the other side is an obtuse angle, and the cutting ability is weak. Light is the main factor, so it has a great influence on the quality of s

Abstract

The invention discloses a fixing mechanism for gear shaving. The fixing mechanism comprises a mandrel, a wavy expansion sleeve, a gland and a driving device, which are sequentially arranged from left to right in the axial direction, wherein the mandrel comprises a clamping part, a shaft shoulder and a fixing part, which are sequentially distributed from left to right in the axial direction, the clamping part is detachably connected with a machine tool, the shaft shoulder can be used for locating the end face of a gear, the wavy expansion sleeve sleeves the fixing part, the wavy expansion sleeve comprises a deformation expansion part and a bearing part, which are sequentially distributed from left to right in the axial direction, the gland comprises a columnar body and a lug boss located at the outer part of the columnar body, the columnar body is in clearance fit with the inner hole of the bearing part, the lug boss is propped against the outer end face of the bearing part, the axial gap between the columnar body and the right end of the fixing part is larger than the axial deformation of the wavy expansion sleeve, and the driving device can drive the gland to move in the axial direction. The scheme is simple in structure, is easy to operate, can firmly clamp a gear workpiece, is convenient for quick shaving, improves the gear workpiece shaving efficiency and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of gear shaving processing, in particular to a fixing mechanism for gear shaving. Background technique [0002] A gear is a toothed mechanical part that can mesh with each other. It is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power; gears are used very frequently in automobiles, and the shaving process is based on a pair of helix angles. The principle of helical gear meshing is that the shaving cutter intersects the axial space of the gear to be cut at an angle, and their meshing is a free generating motion of double-sided meshing without backlash. In the meshing transmission, due to the existence of the axis crossing angle "φ", relative slip occurs between the tooth surfaces along the tooth direction. The slip speed vcut=(vt2-vt1) is the cutting speed of the shaving process. The tooth surface of the shaving cutter is grooved to form a cutting edge, and th...
