(54) TOOLING

dopka 3, convenient for aligning the radio beat pulse.

When machining a knob 3 together, a reciprocating P motion (... Describing the barrel-shaped shape of a guide, for example, the left side surface of the cavity of the wheel being cut, the running-in motion reproduced by the coordinated rotation of the WE knob 3 and the Ba rotation of the workpiece 2, and the movement of Pa Pa. the depth of the notch (tooth) of the wheel being cut.Target 2 (or dolly 3) is also reported to be a reciprocating movement, front, synchronized with the movement T n, which serves to retract the blank (dolby) when idle the dolva px

The movement of Lg is continued until the plunging of the hammer 3 into the tooth height (depth of the cavities) of the cut blank 2 takes place. Then this movement is turned off.

The movements rijj, BZ, B2, and Pose provide the cutting of the depressions and the shaping of the side surface of the teeth 1. This process lasts until the workpiece makes a full turn after the motion Pa is turned off. After that, without interrupting the rolling motion, the workpiece 2 is informed by an additional rotational movement of the incision b, acting until it turns through

φ corresponding to the offset of the tooth of the hammer 3 by an amount equal to the decrease in the thickness of the tooth of the hammer. At the same time, the shape of the movement path P is reversed to correspond to the generatrix of the other (right) side surface of the tooth 1. After movement B stops, the side surface of all cavities (teeth) of the wheel being cut will be formed during a complete rotation of the workpiece 2. Then dolb to tap B the original position and all movements to the angle of the additional

1. The method of gear shaping under rolling conditions of I cylindrical gears with barrel-shaped teeth, carried out in two stages, one of which produces gouging of like, for example, left side surfaces of the teeth, and on the other side surfaces opposite to the first, differing In order to expand the received wheels, dolb to vpolrazmera with teeth, reduced by its pitch circle, not less than by the value of the barrel shape of the wheel being machined, which, when moving from one stage of dolding to another, imparts an additional angular movement of the incision by an angle depending on the magnitude of the tooth drop reduction. 2. The method according to claim 1, wherein the angle is determined from the expression: where f is the angle of the additional angle embedding; The size of the tooth thinning} R radius of pitch circle chuck Sources of information taken into account in the examination 1.
