Reducer is a common machine in today's society. Create all kinds of convenience and safety for our life. Reducer is a power transmission machine. It reduces the number of revolutions of the motor to the speed required. At this speed, a larger torque will be obtained. In our daily life, it is everywhere. Heavy machinery and tools are used in ships, automobiles, locomotives and buildings. Machining tools and automatic production equipment are used in the machinery industry. Common household appliances and clocks in daily life. Its application range includes large power transmission and small load. Any scene that requires accurate angle transmission is the place where the reducer performs his best.
These are the main functions.
1) The function of reducing speed and increasing output torque
Its torque output ratio is obtained by multiplying the output of the motor by the reduction ratio.
2) Deceleration reduces the inertia of the load
The reduction of inertia of the equipment is the square of the reduction ratio. The motor we use has an inertia value. And the reducer can reduce its load inertia.
Working Principle of Reducer
Reducers are used for transmission equipment with low rotation speed and large torque. It uses the gears with few gears on the input shaft in the reducer to mesh the large gears on the output shaft. It is used to reduce the speed of the motor. Ordinary reducers have several pairs of gears with the same principle. It can achieve ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.
Type of reducer
Reducer is a precise machine. It can reduce the rotating speed and increase the torque when applied to the equipment. There are many kinds of it. Different kinds have different uses. Different types of reducers are classified according to transmission types. They are gear reducers, worm reducers and planetary gear reducers. It can be divided according to transmission stages. They are single-stage and multi-stage reducers. It can be divided according to gear shape. They are cylindrical gear reducer, bevel gear reducer and bevel-cylindrical gear reducer. And it can be divided according to the arrangement of transmission. They are expansion type, split type and coaxial type reducer.
The reducer is composed of transmission parts (gears or worms), shafts, bearings, boxes and their accessories. Its basic structure has three major parts.
(1) gear, shaft and bearing combination;
(2) a box body;
(3) Reducer accessories.
They ensure the normal operation of the reducer. Sufficient attention has been paid to the structural design of gears, shafts, bearing combinations and boxes. We should pay attention to the reasonable selection and design of auxiliary parts and components. For example, filling and discharging oil for the reducer lubricating oil tank, checking the oil level height and hoisting.
The above is a simple explanation. I hope you can know something about reducer, a common thing in our life.
