One of the main characteristics of a reducer is its transfer number. This parameter is used when calculating geometrical parameters of various transfers of the mechanism for transfer of the rotary moment and affects accelerating dynamics and the maximum speed of the device.
It is required to you
- - reducer.
Instruction
1. Define to what type of transfers your reducer belongs. They are divided into the following types: conic, cylindrical, planetary and combined. Also there is a distinction on gearing transfers which are gear, gipoidny, chain, belt, screw, wave and fractional. The transfer number for all of them is defined by the relation of frequencies of rotation of the leader and the conducted shaft. If these characteristics are unknown to you, then it is necessary to use other formulas of calculation.
2. Open a reducer cover to get access to its elements. It is necessary to define a type of an element of a reducer on which the way of calculation of transfer number depends.
3. Take the corresponding measurements for calculation of transfer number. For the gear transmission it is equal to the relation of number of teeths of the conducted gear wheel to number of teeths of the leading gear wheel. In this regard it is necessary to count necessary parameters visually. For the belt drive diameter of the conducted and leading pulley is measured then calculates the relation of bigger value to smaller.
4. If your reducer has chain transfer, then count the relation of number of teeths of a bigger star to number of teeths of smaller. The worm gear is characterized by number of calling on a worm and number of teeths on a worm wheel. After their definition there is a transfer number equal to the attitude of the second parameter towards the first.
5. Count transfer number on the speed of rotation of the leader and the conducted shaft. For this purpose it is necessary to use the tachometer and to measure the frequency of rotation of a shaft which sets the power plant in motion. After that the speed of a shaft which sets the working mechanism in motion is defined. Find the attitude of the first parameter towards the second to define transfer number.
