Reducer classification

Time:2020-04-13 15:08:30 Hits:773 次 Source:LUOYANG HONGXIN HEAVY MACHINERY CO., LTD.

The reducer is an independent closed transmission device between the prime mover and the working machine. It is used to reduce the speed and increase the torque to meet the needs of the work. It is also used to increase the speed in some places.

When using the reducer, according to the conditions of the working machine, the technical parameters, the performance of the power machine, the economy, and other factors, compare the difference in type and variety of the outer size of the reducer, transmission efficiency, bearing capacity, quality, price, etc. reducer.

1, reducer classification

There are many types, varieties, and types of reducers. There are more than 40 types of reducers that have been established as the (national) standard. The type of reducer is divided according to the tooth profile and profile curve of the gear used; the variety of reducer is a reducer with a different structure designed according to the needs of the use; the type of reducer is based on the basic structure based on the tooth surface Reducer with different characteristics designed by factors such as hardness, transmission stage, shaft type, assembly type, installation type, connection type and other factors.

2, the load classification of the reducer

The load state of the working machine connected to the reducer is mixed and mixed, and the influence on the reducer is very large. It is the primary factor for the use and calculation of the reducer. The load state of the reducer is the load state of the working machine (driven machine), which is usually divided into three Category: ①—uniform load, ②—medium impact load, ③—strong impact load.

In short, after the power of a general machine is designed and built, its rated power does not change. At this time, the greater the speed, the smaller the torque (or torque); the smaller the speed, the greater the torque.

Sometimes, in order to obtain a large torque, we need to use a reducer to reduce the "primary engine"-such as the speed of the planer, to obtain a large torque.

Commonly used reducers: gear reducers, worm gear reducers, etc.
