Abstract

1293628 Grinding VITEBSKOE PETSIALNOE KONSTRUKTORSKOE BJURO ZUBOO - BRABATYVAJUSCHIKH SHLIFOVALNYKH I ZATOCHNYKH STANKOV 3 July 1970 32437/70 Heading B3D A machine for grinding a worm hob 4, comprises a piston fixed rigidly to the frame of the machine and a cylinder 9 slidable on the piston and in guides 11, the cylinder being formed with a rack engaging a gear 13 on a shaft 2 connected to a differential mechanism A having a device 45 for effecting circular feed of the workpiece and a device 40 for taking up play in the kinematic chains of the machine. The shaft 2, on one hand, is secured to a gear 26 co-operating with a rack 27 for effecting reciprocation of a carriage 5 for a grinding head 6, and, on the other hand, is connected by a clutch 14 to the input shaft 15 of the differential mechanism A. The latter is carried by supports 16 in a housing 17 which also includes the guides 11 for the cylinder and bearings for the shaft 2. The mechanism A has gears 30 ... 33, connected to gearing 34, 35, bevel gears 36, 37, change speed gears 20 ... 24, indexing mechanism C and spindle 3 to which the hob is secured. After each to-and-fro movement of the carriage 5 carrying the grinding head effected by reciprocation of the cylinder 9, a circular feed is imparted to the hob by operation of a step-by-step motor 45 connected to a worm 42 meshing with a worm gear 43 on housing 44 for the differential gears 30 ... 33. Play in the gearing is taken up by a piston 41 in a cylinder 40 acting on the worm 42.
