Description

perpendicular to the plane of the axes of the spindles 1 and 2, and kinematically connected with the drive mechanism 9. The latter consists, for example, of an engine, a belt transmission of a worm gear and a link mechanism. In the end hollow part of the spindle 1, the tool holder 10 is mounted, which carries the tool 11 (for example, the cutter), the longitudinal feed mechanism 12 and the cross feed device .13. On the spindle 2 is rigidly mounted billet conical gear 14.
When the machine is in operation, the drive mechanism 9 drives the reciprocating movement of the slider 7 with the gear racks 5 and 6 rigidly mounted on it, which ensure the rotation of the shafts 1 and 2 with different angular speeds (coi) 2), which corresponds to the rolling without sliding the base H of the initial the cylinder of the ring gear 4 at the base of the Jaz of the initial cylinder of the ring gear 3. The instantaneous center of speed when rolling the bases of the Jaz and H is the point R. The indicated rotation of the spindles imitates the running movement of the conical shev The gauge 14 on the face plane of Yaz, in this case, a cone with an apex angle of 2 b is taken as the calculated axoid to obtain the specified working running-in motion. Thus, the tool (cutter) installed in the tool holder 10 at the level of the base plane of the Yaz, in relative (working) motion, describes a trajectory in the form of a developing curve (spatial evolvent) that coincides in a certain area with the nominal surface of the tooth tooth, which provides cutting of particle grooves, the bottom surface of which is equidistant to the main surface of the teeth of the conical gear Shaver.
The possibility of cutting chip grooves on conical gear shavers of different geometrical dimensions is carried out by rebuilding the machine by changing the angle 2 of crossing the axes of spindles I and 2, setting the initial planes of the rails 5 and b at the same angle, as well as selecting the radius r of the initial circumference of the gear 4.
These settings are determined by the ratios
r. S 8 + 90 °,
where b is the angle of the cone, taken as an axoid in the implementation of the calculated rolling motion; TI is the radius of the initial circumference of the ring gear 3.,
