Abstract

This invention relates to a machine tool industry, in particular to the manufacture of gear wheels. The purpose of the invention is the expansion of technological capabilities due to the creation of conditions for obtaining gears with an initial wavy surface. A table for securing the machined wheel 1 on spindle 2, a caliper 4 for securing spindle 5 knuckle 6 are placed on the frame of the gear-shaping machine. Spindles 2 and 5 are connected by a kinematic run-in chain, the final links of which are placed on the spindle 5 worm to 7, worm The main wheel 8, and on the spindle 2 - gears 9 and 10. In the machine, the chain of additional cyclic translational movement or spindle 2, or spindle 5 is introduced and connected to one wheel of the separator pair. oh chain. 3 hp f-ly, 5 ill.

Claims (4)

Claim 1. A gear-shaping machine, comprising a link for a spindle of a dolbyak with a rolling spindle located on the table, a run-in chain with final links in the form of gear dividing pairs, the wheels of which are placed on the spindles, a chain of radial feed of the dolby and the purpose of the longitudinal installation movement of the bearing spindle of the groove of the caliper, made in type of drive connected to a conical pair, the driven wheel of which is rigidly connected to a nut located coaxially with it, interacting with a screw mounted on the support, characterized in that, in order to expand technological capabilities by creating conditions for producing cylindrical wheels with an initial wavy surface, the machine is equipped with an additional cyclic translational displacement chain connected to the wheel of one of the gear dividing pairs. 2. The machine according to claim 1, characterized in that the chain of additional cyclic translational movement is connected on one side by the spindle wheel of the cutter, the other - with the chain of the longitudinal installation movement of the caliper - and is made in the form of a cam rigidly fixed to the worm wheel, interacting with the rocker arm with a roller and gear system designed to link the beam to the driven wheel of the chain longitudinal installation movement. 3. The machine according to claim 1, characterized in that the chain of additional cyclic translational movement is connected on one side with the spindle wheel of the product. on the other hand, with a table and made in the form of a crank mechanism, one end of the connecting rod of which is designed for articulation with the bed of the machine, the other end is pivotally connected to the finger of the crank placed on a slider designed for placement on the bed with the possibility of translational movement, the crank is connected to the spindle of the wheel and to the axis of the table with the help of a universal joint inserted into the machine. 4. The machine according to claim 1, with the fact that the chain of additional cyclic translational movement is connected on one side with the spindle wheel of the product, on the other hand, with the table and is made in the form of a crank a slider of the sine mechanism, the link with the stone of which is connected with a crank placed for rotation on a slider intended for installation on a bed, while the crank is connected to the spindle of the product and to the table inserted into the machine by a universal hinge. / 25 Figure 3
