Problems solved by technology

[0003] At present, the power source of the main shaft rotation of the lathe mainly comes from the electric motor. The existing adjustment of the main shaft speed is mainly completed in the exchange gear box. The principle of exchange gear shifting is mainly through the transmission of gears with different transmission ratios. First of all, relying entirely on this speed change method requires multi-stage speed change, so the overall volume of the exchange gearbox is relatively large; secondly, continuous change of transmission ratio cannot be achieved through gear change

Abstract

The invention discloses a stepless speed change device. The stepless speed change device comprises a motor, a speed reducer, a split box body, adjustable belt wheels, a wide V belt and an adjusting device, wherein the split box body comprises an upper box body and a lower box body which are connected with each other; the upper box body is connected with the output end of the motor; an upper end cover is arranged on the outer side of the upper box body; an output shaft of the motor is rotatably connected with the upper end cover; the lower box body is connected with the input end of the speed reducer; a lower end cover is arranged on the outer side of the lower box body; an input shaft of the speed reducer is rotatably connected with the lower end cover; adjustable belt wheels are arranged on the output shaft of the motor and the input shaft of the speed reducer; the wide V belt is connected with the adjustable belt wheels on the output shaft of the motor and the input shaft of the speed reducer. The stepless speed change device is small in overall size; the transmission ratio can be continuously changed.

Description

technical field [0001] The invention relates to a continuously variable transmission device. Background technique [0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on the lathe. The main components are: spindle box, exchange gear box, feed box, slide box, tool holder, tailstock, feed rod, lead screw, bed, bed foot and cooling device, etc. [0003] At present, the power source of the main shaft rotation of the lathe mainly comes from the electric motor. The existing adjustment of the main shaft speed is mainly completed in the exchange gear box. The principle of exchange gear transmission is mainly through the transmission of gears with different transmission ratios. First of all relying entirely on this speed change method requires multi-stage speed change, so the overall volume of the exchange gear box is relatively large; se...
