A continuously variable transmission is a mechanical transmission device that can provide stepless, continuous gear ratio output. Its main features are:
1. Wide gear range, stepless gear shifting, and smooth transmission.
2. The gear ratio is continuously variable, allowing the output speed to be either lower than or higher than the input speed.
3. The gear-shifting process is smooth, enabling seamless gear changes without vibration or impact during operation.
4. High transmission efficiency and strong transmission capability
Common types of continuously variable transmissions include:
1. Frictionless Continuously Variable Transmission: This type of transmission relies on the frictional force between two relatively movable wheel systems to transmit motion and power, such as the friction-disc type and the hydraulic transmission type.
2. Gearless Continuously Variable Transmission: A continuously variable transmission that utilizes the hydrodynamic coupling principle of low-viscosity oil, such as a hydraulic torque converter.
3. Planetary Gear System: Utilizes the principle of planetary gear motion to achieve stepless speed variation, such as in wave gears and planetary gears.
Continuously variable transmissions are widely used in fields such as machine tools, medical equipment, construction machinery, and wind power. They can achieve ideal motion control and power transmission, ensuring optimal operational performance of machines.
