Description

A well-known construction of a ground milling cutter for cutting worm wheels, which has one tooth for each run, a worm gear.

However, such a milling cutter at re-grinding loses the necessary razderyy and, moreover, for the grounding it is necessary to have a backing machine, which is practically difficult to carry out in small factories and in various workshops.

A distinctive feature of the worm frame design is that the 5b-volt consists in the fact that it is made as a team and consists of a mounted screw with a partial whip and an eccentric ring entering the hole of the screw, which, when the cutter is mounted on the sinella of the hoofing machine, ensures the formation of the back ring angle and STANDING 1P-1YY departure 3v6a.

This feature provides a possibility of eliminating the backing operation and increasing the number of refills without losing the size of the cutter.

FIG. 1 shows the type of cutter-bat from the end; in fig. 2-view of the cutter-bat on top.

Cutter J is an incomplete W1HGOK 2 worm with a parameter-ram producing a screw sucker hopper for the worm milling cutter, adapted for the cut wormwheel. One end of coil 2 is cut off and sharpened so that a front surface forms on the cutting coil tooth with the required rake angle.

The milling cutter is / is put on an eccentric pa; an adjusting ring 4, which is attached to the ipdel 5 of the gear milling machine. The turn of the 4-cut relative to the eccentric ring is used to regulate the position of the coxperitic surface of the vitkubub,. This creates a tooth protrusion and a gap is formed between the ground surface 7 and the rear surface O of the cutter tooth, which becomes the B - side, which is as if ground and works with the required angle 1. After each regrinding of the cutter, a slight rotation is made to maintain constant values of the tooth and the rear angle.

Worm milling cutter for cutting worm KO,: i.e., excellent; i with that, with the whole

excluding the backing operation and increasing the number of refills without losing size, it is made of a national team and consists of a mounted cylindrical screw with an incomplete 5-tooth and an eccentric ring entering the hole of the screw, which, when the cutter is mounted on the spindle of the Hub saw, creates nyu departure tooth.
