Background technique
At present, known gear is generally that common electric machine directly is connected with variable-speed motor, can keep off by manual many quick changes, numerical control machine tool is not generally shifted gears now, more advanced can only high and low two gears, there is no middling speed and the gear shift fork support roller quick abrasion commonly used, while using especially, fault is more.Also because there is no high, medium and low three class gear shift machine, slewing range is little, and is large in bite especially, can not meet processing request while needing low-speed big.If strengthen two grades of speed ratios, meet high pulling torque and high rotating speed, just there is no intermediate cut torsion and speed commonly used.
Summary of the invention
The technical problem that will solve of the present invention is, numerical control machine tool is not generally shifted gears now, more advanced can only high and low two gears, there is no middling speed and the gear shift fork support roller quick abrasion commonly used, while using especially, fault is more.Also because there is no high, medium and low three class gear shift machine, slewing range is little, and is large in bite especially, can not meet processing request while needing low-speed big.If strengthen two grades of speed ratios, meet high pulling torque and high rotating speed, just there is no intermediate cut torsion and speed commonly used.
the technical solution adopted for the present invention to solve the technical problems is, gear is comprised of motor and gearbox, it is characterized in that motor is fixed on gearbox, driving shaft is connected with motor, the first driving shaft gear in gearbox, the second driving shaft gear and the 3rd driving shaft gear are fixed on driving shaft, driven shaft gear is contained on driven shaft, the gearshift triple gear is contained on driven shaft, gearshift hydraulic cylinder piston pull bar one end connects bearing pin by triple gear and triple gear connecting pin retaining back-up ring is connected with the gearshift triple gear, the gearshift hydraulic cylinder piston pull bar the other end passes through rolling bearing, hydraulic cylinder piston pull bar fixture block back-up ring and piston capping are connected with hydraulic cylinder piston, the gearshift hydraulic jack is fixed on gearbox, the piston guide screw is contained on the gearshift hydraulic jack, hydraulic cylinder piston is provided with opening slot, coordinate with the shift cylinder electromagnetic locator along the piston guide screw and pull the gearshift triple gear to carry out height, in, low three class gear shift, thereby met the height of gear, in, low three class gear shift demand, and original selector fork and support roller have been saved, utilize mesopore gearshift location, without wearing and tearing.
The driven shaft intermediate portion is the splined shaft of longitudinal opening.
The driven shaft gear end is provided with internal gear, and coordinates with driven shaft after the small gear engagement by gearshift triple gear one end, drives driven shaft and transmits torsion and rotating speed.
Gearshift hydraulic cylinder piston pull bar is placed in driven shaft inside, can move forward and backward and with driven shaft, rotate.
The invention has the beneficial effects as follows no longer and increase middling speed with gear shift fork and support roller, namely third gear adds stepless change, is the state-of-the-art variable-speed motor in the present world, and its slewing range is large, can realize high, medium and low gearshift.Not only be applicable to various numerical control machine tools, and can also meet other NC heavy mechanical speed change needs.
