Description

This invention relates to a structure and can be used in the machining of gear wheels.

The aim of the invention is to expand the technological capabilities of machining wheels with a longitudinal modification of the teeth.

The drawing shows the device,, view.

- The device includes a housing 1, a spindle 2 on which rack gear 3 is mounted, forward couplings 4 and reverse 5 couplings 5. Couplings 4 and S are connected by a pull 6. Instrument 7 is mounted on a slider 8. Rotation of the return axis 5 is faster than the couplings 4 straight h.da by means of a planetary gear 4 {ih. On spindle 2 there is a copier 01 with a finger 11. A slider 8 with a tool 7 is installed on the carriage 12, and on the spindle 2 a second 131 is installed ;; finger 14, gfichy fingers G1 and 141 are installed on the carriage 12.

When the tool travels, the 7th gear 3 is transmitted from o-2 via the coupling h. The clutch 4 of the clutch 4 is produced by the roller 16, and at the same time by the thrust of the clutch 6, the clutch is inserted ;; the persistent. -Annage S. The reverse clutch 3 is rotated with: twice as large frequency through the planetary gear 9. housing 1 parallel to the axis of the spindle 2. Crawl 8 with the tool 7 and the rail 17 moves in the guides of the carriage 12. During one working and return stroke of the slide 8, the carriage 12 is not |) moved with a finger 11 and

 copier 10 installed with a given g, depending on the magnitude of the longitudinal modification of the eccentricity. When processing one side of all the teeth, one of the fingers (11) stops and the other (14) presses the spring surface of the second copier 13 by means of the spring 18. When the second side of all the teeth starts to roll, the second finger 14 stops and the first 11 presses the spring 11 to your copier. During one revolution, spindle 2 takes one, the cycle of reciprocating movement of the slide 8 with the tool 7 and the carriage 12. The setting of the kinematic chains of a hobbing machine is similar to the processing of worm wheels with tangential feed of the tool. With a barrel-shaped longitudinal mode} -; - fication of a tooth, the eccentricity value is determined by the formula

where oik is the angle of the profile of the helical groove of the copier 10 or 13.
