Function

The high efficiency gearbox mainly refers to the gearbox of the automobile, which is divided into manual and automatic two kinds. The manual transmission is made up of gears and shafts, resulting in variable speed torque through different gear combinations. The automatic transmission is composed of hydraulic torque converter, planetary gear, hydraulic variable pitch system and hydraulic control system. The change torque is achieved by the combination of fluid and gear.
Function: 1. Change the transmission ratio; 2. In the same direction of rotation of the engine, the car can be driven backward; 3. Use the gap, interrupt power transmission to enable the engine to start up, idle speed, and facilitate transmission change or power output.

Overview

Gear speed reducer is generally used in low speed high torque transmission device, the ordinary motor reducer also can have a few on the same principle gears to achieve the ideal effect, the size of the ratio of the number of teeth on the gears, transmission ratio. With the development of the speed reducers industry, more and more enterprises have adopted the speed reducers.

Speed control method

The gear speed reducer is a decelerating motor with fixed speed. Once the speed ratio is selected, the motor reducer is selected and the final output speed is fixed. Various speed control methods used in pre-engineering.
1. It is the simplest and most economical method for speed adjustment. There are usually only two speeds, and the speed adjustment ratio is smaller (l: 2, 1, 6) and the limit is three. The speed of regulation is small, although it has the speed.
2. Stepless speed regulation can be divided into mechanical and electrical. The former common method is to insert mechanical stepless speed adjusting device in the connection of motor and gear box. The advantage is that the speed reducers is stable, the structure is not complicated, it is suitable for the bad environment; The disadvantage is that the belt and friction plate of the speed range is a consumable part, which needs to be replaced regularly. The latter is for the asynchronous motor to perform cascade speed regulation, rotor resistance speed regulation or to the dc motor to adjust speed regulation.

Brief Analysis: Characteristics of Conventional Hardened Reducer

1. Conventional hardened large industrial gearbox load capacity is high. Gear with carburizing, quenching, grinding processing, carrying capacity than the quenched and tempered hobbing tooth surface and the hard tooth gear reducer has greatly improved.
2. Small size and light weight. Compared with soft tooth and medium hardened gear reducer. The same carrying capacity Reducer can reduce the 2-4 quite seat size.
3. High efficiency, low noise, small vibration. With the grinding processing to improve the accuracy level, the industrial gearbox types has been repaired, each stage of the integrated efficiency of 0.98, vibration and noise significantly reduced.
4. Using multi-stage, single stage gearbox single-stage ratio. Can open the center distance, reduce the height of the reducer, to meet the requirements of the crane agencies; reducer maximum nominal transmission ratio of 400, to meet the requirements of the slow crane.
