A speed reducer, also known as a gear reducer or gearbox, is a device used to decrease the rotational speed of machinery or equipment.
Speed reducers function through three primary methods: gear, friction, and hydraulic reduction. Gear reduction changes the speed using different gear sizes, friction reduction employs resistance, and hydraulic reduction uses fluid pressure to decrease speed. These devices are crucial in industries like manufacturing, construction, agriculture, automotive, and railways for various applications.
The components of a speed reducer include input and output shafts, gears, bearings, and lubricants. Important characteristics to consider when choosing a speed reducer are the reduction ratio, torque, efficiency, noise level, and vibration. Factors such as the application's requirements, reduction ratio, torque, efficiency, noise, and vibration are vital in the selection process.
