Embodiment

[0028] This embodiment proposes a method for machining an inner circular groove of a spiral bevel gear, which includes the following steps:

[0029] Step a, tie the groove

[0030] Such as figure 1 As shown, use the GX24-3E500N04-UD4 type grooving knife, the grooving knife speed is 180r / min, the feed rate F: 0.3~0.45, the straight part of the inner circular groove of the spiral bevel gear is cut, and the middle straight part is selected according to the groove width One groove point, the depth of the groove is taken as the lower limit of the final size to exceed 0.1mm, the purpose is to form a linear part finish turning tool relief groove, and the iron filings on the straight part are cut and curled laterally when the inner circular groove groove is finished later. Then, select three groove points on the straight line arc and angle arc according to the length of the arc, and the depth of the groove to the final size of the inner arc. Steps, when the inner circular groove is ...

Abstract

The invention provides a machining method for finish turning of an inner circular groove of a spiral bevel gear. Compared with an original traditional machining method of directly and circularly feeding according to the shape of the inner circular groove, by changing a machining path, firstly, a plurality of grooving points are selected from a linear arc and an angle connecting arc of the inner circular groove to form a plurality of steps when grooving is conducted through a grooving cutter; machining of the inner circular groove is simplified into three-step machining according to the shape of the inner circular groove, specifically, grooving is conducted firstly and then semi-finish machining is conducted on the shape of the arc groove, finish machining is conducted on the shape of the arc groove; and an effective grooving path is designed to cut off transverse curling of scrap iron, the scrap iron breaking situation can be improved, and the scrap winding situation is reduced. The method is simple and easy to implement, the quality of the machined surface can be guaranteed, and then the machining and clamping process exchange efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of spiral bevel gear processing, and in particular relates to a method for machining inner circular grooves of spiral bevel gears for reducing the chip wrapping rate in turning inner circular grooves of spiral bevel gears. Background technique [0002] Spiral bevel gear is a gear part with high transmission efficiency, stable transmission ratio and high load capacity. It is usually made of high-quality alloy steel such as 18Cr2Ni4WA and 20Cr2Ni4A. These materials are typical high-strength and high-toughness alloy steel. In the process of processing such materials, the problem of poor chip breaking effect of iron chips will occur, which will cause chip entanglement. At the same time, due to the special shape of the inner circular groove, when turning the inner circular groove with a certain depth and a narrow groove connected to the arc, the traditional processing method of circular cutting according to the g...
