On each power transmission shaft to lead moving plate top-bottom cross overlapping, during installation, lead the front end of moving plate towards in the middle part of bottom plate；
Also include driving disc spacing pressing, the bottom of driving disc spacing pressing is arranged on case top by needle bearing, had on driving disc spacing pressing from the center of circle
The elongated hole to edge is opened up, axial slideway is all provided with two long hole walls of the elongated hole, is fixed with the top of speed control rod
Sliding block, the sliding block at the top of speed control rod are placed on driving disc spacing pressing in the slideway of elongated hole, speed control rod be interspersed in respectively lead it is elongated on moving plate
In hole, fixed sliding block is connected with screw mandrel the inner at the top of speed control rod, and screw mandrel installation passage is also provided with driving disc spacing pressing, described
Screw mandrel is located in screw mandrel installation passage, and the outer end of screw mandrel is stretched out from driving disc spacing pressing, the screw mandrel installation passage on the driving disc spacing pressing and
Elongated hole be further opened with the same line, on driving disc spacing pressing rack-and-pinion installation elongated hole, described rack-and-pinion installation elongated hole with
Screw mandrel installation passage is vertically arranged close to driving disc spacing pressing center of circle end, and gear is connected with wire rod thread, and the top of gear is from rack-and-pinion
Installation elongated hole in expose, rack be located at rack-and-pinion installation elongated hole in, the geared surface of rack engages with gear, rack without the flank of tooth
Contacted with the hole wall of rack-and-pinion installation elongated hole, speed regulation wrench is fixed with the top of rack.Lift or push speed regulation wrench, rack
Pinion rotation is driven, pinion rotation drives screw mandrel to move forward and backward, so as to drive speed control rod to be moved in the elongated hole of driving disc spacing pressing.
It is an advantage of the invention that：In use, by the power output axis connection of the driving disc spacing pressing of the present apparatus and engine, driving disc spacing pressing
Rotate and drive speed control rod to rotate, speed control rod rotates in the elongated hole for respectively leading moving plate drives each power transmission shaft to swing, each power transmission shaft pendulum
It is dynamic to drive external gear to press defined direction rotation by unilateral bearing, so as to drive internal gear to rotate, export power output shaft
Power, by adjusting position of the speed control rod in driving disc spacing pressing elongated hole, speed change can be achieved, when speed control rod is close to active disk center
When, the rotating speed of power output shaft is minimum, and during close to active plate edge, the rotating speed of power output shaft is maximum, when speed control rod is positioned at master
During Moving plate center, power output shaft stops operating, unpowered output.Its is simple in construction, operates steadily during speed change, power attenuation
Few, input and output end can be synchronous, without clutch.
