The purpose of this utility model is to design a kind of planetary gear type stepless variable speed device at the above-mentioned defective of prior art existence, can realize level and smooth speed change, and high-power transmitting torque is made simply, and cost is low.
Summary of the invention
Main structure of the present utility model is as follows: the planetary gear type stepless variable speed device, comprise main shaft and output shaft, it is characterized in that it is made up of active input planet gear mechanism, variable speed planetary gear mechanism, speed governing planetary gears and control mechanism, initiatively input planet gear mechanism is by active output gear engagement variable speed planetary gear mechanism, the variable speed planetary gear mechanism and the output gear engagement of making a concerted effort, the output gear transmission output shaft again of making a concerted effort; The speed governing input gear of speed governing planetary gears is connected with control mechanism, and speed governing output planetary gear also meshes with the output gear of making a concerted effort; Initiatively planetary carrier and variable speed planetary gear frame mesh with cone gear respectively, and variable speed planetary gear frame and speed governing planetary carrier connect as one.
Transmitting torque mainly plays in above-mentioned active input planet gear mechanism; Variable speed planetary gear mechanism is that as required I/O commentaries on classics value recently realizes the definite value transmitting torque; The speed governing planetary gears is used to control the component size; Control mechanism mainly is the input torque of control speed governing planetary gears.
The working principle of this mechanism is: the planetary pinion of planetary gears is when transmitting torque, the planetary carrier that supports it will produce the reaction force suitable with it, control its stressed size, to change the speed between planetary pinion rotation and the revolution, can change the speed between its output torque and input torque, reach the purpose of slip speed change.
The advantage of this structure is: can realize level and smooth stepless change, high-power transmitting torque is made fairly simplely, and cost is relatively low.
