The three most important factors to choose a reducer are power, speed ratio, and torque. In addition to these three important factors, the following factors must also be considered. The right and wrong of the reducer's daily working hours; machine start and stop frequency; operating cycle; machine Robust accuracy requirements; desired motor output speed n; working environment temperature of the reducer; load type; good or compact heat dissipation on site, etc.

If you want the reducer you choose to be firm and long-term, you must consider every detail, and strive to make the reducer you buy the most correct and most suitable reducer for you. Cycloid reducer and the sealing part are running at high speed and high temperature for a long time, and oil leakage in the sealing part sometimes occurs. Due to the serious oil leakage during equipment operation, which brings many disadvantages to safe production, the traditional method is to stop for a long time to disassemble and replace the sealing gasket and deal with the joint surface. In order to achieve effective treatment during equipment operation, traditional methods cannot be achieved.

Reducer selection method

The reducer is an ingenious idea transmission device, which must be carefully selected before purchasing. There are usually two modes of load, namely continuous and recurrent modes. The continuous type selection is mainly based on the customer-set torque of the reducer, and the cycle mode is mainly based on the peak torque of the reducer. There are usually two methods.

1.rough disk algorithm
2. Correct disk algorithm. When you can ensure that your mechanical load will not exceed the rated torque of the motor and reducer, you can use a rough calculation method to choose the reducer, but in order to ensure the stable operation of your mechanical insurance, we encourage you Use the correct disk algorithm to choose the reducer.
The following will introduce you to the judgment of load mode and the method of selection and calculation
One, load mode judgment
2. Continuous mode selection order
Three, selection method
Four, calculation formula
1. When the load is in continuous mode, the minimum rated torque that must exist for the selected reducer
2, when the load is in cycle mode, the minimum peak acceleration torque that the selected reducer must exist
3, load torque
4, the modified torque of the load
5, the uniform speed of the load
6, load maximum input speed
7, the necessary torque of the reducer
8. The continuous time rate of the maximum torque in the load where Emax is the continuous time rate of the maximum torque in a cycle, and Tmax is the continuous time of the maximum torque in the load.
9. Allowable torque of reducer
10, uniform load torque

The reduction gear selection includes the steps of proposing the original premise, choosing the type, and judging the specifications.

In comparison, the type selection is relatively simple, and the condition of supplying the reducer correctly, and the control of the design, manufacturing and utilization characteristics of the reducer are the keys to the correct and fair selection of the specifications of the universal reducer. Planetary cycloid reducer is a relatively new type of transmission mechanism. Its unique and stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases, because the planetary cycloid reducer has high speed ratio and high efficiency, and has a compact structure. , Small size, stable operation, low noise, reliable use, long life, reasonable design, convenient maintenance, easy to disassemble and install. The specification selection must satisfy the premises of strength, thermal balance, and radial load on the shaft extension.

When installing the reducer, the center axis of the transmission should be centered, and the error should not be greater than the compensation amount of the coupling used. Good alignment can prolong the service life and obtain fantastic transmission efficiency. When installing the transmission part on the output shaft, it is not allowed to hit with a hammer. Usually, the assembly fixture is used to press the transmission part in with the internal thread of the shaft and the bolt is used to press the transmission part in. Otherwise, it may cause damage to the whole machine inside the reducer. It is best not to use rigid fixed couplings, because improper couplings of this type will cause unnecessary external loads, and even cause early damage to the bearings, or even break the output shaft in severe cases.
