Classification and main characteristics of common reducer in mixing equipment

(1) The cylindrical gear reducer and bevel gear reducer are all gear reducers, among which the cylindrical gear reducer is the most widely used in all alkali speed machines. The range of transmission power can be from very small to 4000kW, and the circular speed can also be from very low (V ≤ 8m/s) to 60-70m / s; The position of the transmission shaft and output shaft of the bevel gear reducer is 90 ° so it is suitable for the vertical position of the input and output shafts.

The main characteristics of gear reducer are high efficiency, durable work and simple maintenance. According to the series of gear reduction, it can be divided into single stage, two stage, three stage or even multi-stage; According to the mutual configuration of its axis in space, it can be divided into vertical and horizontal; According to the characteristics of its motion diagram, it can be divided into expansion, coaxial and split flow.

In order to avoid the large external dimension of the reducer, when the transmission ratio is below 8, the single stage gear alkali speed machine should be used. When the ratio is less than 8, it is better to select two-stage gear reducer (i= 8-40) and more than two (i>40)).

(2) Worm speed machine is mainly used in the occasions with large transmission (I > 10), which has the advantages of compact transmission structure, small outline size and stable working, but the efficiency is low. Therefore, single-stage worm gear reducer is widely used, and two-stage worm gear reducer is less used. The range of transmission ratio of single stage worm gear reducer is generally i= 10~-70.

(3) The main characteristics of planetary gear reducer are high transmission efficiency, wide transmission ratio, transmission power from 10W to 50000kw, and the volume and weight are much smaller than that of ordinary gear reducer and worm gear reducer. But its structure is complex and the manufacturing precision is required to be high
