Description

112

This invention relates to mechanical engineering and can be used in machining gears of large modules.

The purpose of the invention is to increase the productivity of tooth processing by eliminating tool changes and nosity by fixedly installing cutting tools for chamfering on the base of the tool for cutting.

The drawing shows a chamfering pattern at the ends of a wheel tooth by an installed tool block.

The processing method is carried out by the cutting tool 1, cutting the tooth of the wheel 2, followed by removal of the chamfer at the ends of the teeth 2. The rolling tool for chamfering is made in the form of a cutting block 3, which is mounted on the tooth of the rolling tool 1, designed for cutting teeth, at an angle about the front surface 4 and symmetrically relative to the middle line of the tooth of the tool 1.

Installing an additional tool block 3 on the tooth of tool 1 reduces the time required to remove tool 1 and install a new tool for chamfering. The location of the plane of the cutting edges at an angle to the front surface of the tooth

tool 1, recommended in the range of 30-45 °, provides cutting conditions that exclude the formation-. burr at the cutting edge exit from the cutting zone. The installation of the incisal block 3 on the tooth of the tool 1 is performed in such a way that the axis of symmetry of the profile of the block 3 coincides with the axis of symmetry of the tooth of the tool 1, thus the points of the edge edges corresponding to the constant chord of the tooth cavity are located at the same distance from the axis of symmetry and provide constancy of the removed allowance.
