Y38-1 gear hobbing machine how to process 46 teeth spur gear and how to change wheel
(2) the number of vertical knives *S stand =a1*c1/b1*d1: horizontal knife, fixed number *S, flat =a1*c1/b1*d1.S vertical vertical walk, S level - Horizontal knife.The number of vertical knives is 3/4, and if the worm gear on the machine tool is 2/24, the number of vertical knives should be 3/10.The number of horizontal knives is 5/4.
Select the cutting speed and hob diameter according to the modulus. Hob speed n=1000*V/ PI *d. Select the gear change wheel accordingly. Right or left hob can be used when milling the spur gear. When cutting, the tool holder is rotated at an angle, so that the blade edge of the hob is in accordance with the direction of the straight gear, that is to say, a spiral angle of the hob is rotated. Verify the machine has been adjusted, and start the machine, roll before cutting, first make hob micro touch workpiece surface, to see whether the teeth, whether the number of teeth, after verification, and then enter the formal processing.
(1) calculation of gear hob: the number of teeth determined (24) *K/Z=a*c/b*d; K- hob head number, Z- teeth number.24/46= (60/30) * (24/92).
