Transmission principle of continuously variable transmission:
While turning the handwheel to drive the speed control cam to change the angular position, the end surface curve of the speed control cam acts on the flat pin clamp and the end surface curve of the fixed cam to cause the speed control cam to move axially, thereby uniformly changing the speed control cam and the fixed ring The interval between the tapered planetary friction wheel produces radial movement.Finally, the working radius of the friction between the planetary friction wheel and the driving wheel, the pressure plate and the fixed ring, and the speed control cam is evenly changed to realize stable stepless speed change.
When the speed changer rotates the hand wheel to drive the speed control cam to change the angular position, the end curve of the speed control cam acts on the flat pin clamp and the end curve of the fixed cam to cause the speed control cam to move axially, thereby evenly changing the speed control cam and The space between the fixed rings causes the tapered planetary friction wheel to move radially.Finally, the working radius of the friction between the planetary friction wheel and the driving wheel, the pressure plate and the fixed ring, and the speed control cam is uniformly changed to realize stable stepless speed change.
The speed changer is high-strength, and the machine has reliable performance and can rotate accurately when the impact load is applied or the machine reverses.Large speed range: the speed ratio is 1:5, that is, the output speed can be arbitrarily changed from 1:45 to 1:7.25.High speed regulation accuracy: speed regulation accuracy is 1-0.5 revolutions.The performance is stable, the transmission parts of this machine are all subjected to special heat treatment, the friction parts are processed with precision, the lubrication is good, the operation is stable, the noise is low, and the life is long.Coaxial structure, input shaft and output shaft rotate in the same direction, small size and light weight.The combination ability is strong. This machine can be combined with various types of reducers to achieve low-speed, large-torque variable speed effects.Under the condition of allowable load, the set speed is constant; the whole machine is sealed, which can be applied to the humid, dusty, and slightly corrosive working environment.
