Axle Breakage in Reducer Output

In addition to the concentricity of the reducer output assembly is not good, resulting in the breakage of the reducer shaft, if the output shaft of the reducer is broken, there are no more than the following reasons.

First of all, the incorrect selection results in insufficient output of the gearbox. Some users mistakenly believe that as long as the rated output torque of the selected reducer meets the working requirements, in fact, otherwise, first, the rated output torque of the distribution motor multiplied by the deceleration ratio, the value obtained is in principle smaller than the rated output torque of the similar reducer provided by the product sample, and second, it should also be considered. The overload capacity of the driving motor and the maximum working torque required in practice. In theory, the maximum working torque required by the user. Must be less than 2 times the rated output torque of the reducer.

Especially in some applications, this criterion must be strictly …

Correct Installation of Reducer

Correct installation, use and maintenance of reducer is an important link to ensure the normal operation of mechanical equipment. Therefore, when you install planetary reducer, you must strictly follow the following installation and use related matters, and carefully assemble and use.

The first step is to confirm whether the motor and reducer are in good condition before installation, and strictly check whether the dimensions of the parts connected by the motor and reducer match. Here are the dimensions and tolerances of the positioning bump, input shaft and reducer groove of the motor.

The second step is to screw down the screw on the outer dust-proof hole of the reducer flange, adjust the PCS clamping ring to align the side hole with the dust-proof hole, and insert the inner hexagon to tighten.

After that, remove the motor shaft key.

The third step is to connect the motor with the reducer naturally. When connecting, it is necessary to ensure that the concentricity of the output shaf…

How to Choose Reducer

The selection of general reducer includes the steps of putting forward original conditions, selecting types and determining specifications.

In contrast, the selection of type is relatively simple, and the key to the correct and reasonable selection of specifications of general reducer is to accurately provide the working conditions of reducer and master the design, manufacture and use characteristics of reducer. Specification selection should satisfy the conditions of strength, thermal balance and radial load bearing at the axle extension part.

1. Select specifications according to mechanical power or torque (strength check)

The biggest difference between the general reducer and the special reducer is that the former is suitable for all industries, but the deceleration can only be designed according to a specific working condition. Therefore, when selecting the reducer, users need to consider different correction coefficients according to their requirements. The factory should select …

What are the reasons for the series axle of reducer?

People who often deal with machinery know that reducer is an essential auxiliary equipment in some machinery, because some machinery will run at a dangerous speed quickly, so it is necessary to use reducer to balance its movement speed. However, in the process of using reducer, the reasons for the series axles of reducer are mastered from the following three points.

1. Series of axes occur because the broken teeth make the input shaft lose its axial restraint, and the driven gears on the middle axle are not tightened tightly with the axle. In actual transmission, because of the insufficient interference between the driven gear and the intermediate shaft, the driven gear produces axial series motion relative to the intermediate shaft, which makes the input shaft produce axial series motion. Therefore, insufficient interference is the main reason for the series axle of reducer. In addition, the steering of the reducer has a certain impact on the series axle.

2. Gear processing deviation…

Attention should be paid to these three points when installing planetary reducer correctly

The problem of how to install planetary reducer correctly has been introduced to you in the previous information, but some users will inevitably encounter some problems in the process of installation. In order to solve your questions, the general reducer summarizes three points of attention for you to install planetary reducer correctly:

Firstly, before installing planetary reducer, we should confirm whether the motor and reducer are damaged, check whether the dimensions of the parts connected with the reducer match, especially check whether the motor bump and stop match the reserved tolerance of the reducer. If the motor bump is too small, it will cause the motor and reducer to be different from each other, which is easy to make. The motor shaft is twisted and bent.

Secondly, when connecting the motor to the reducer, if the shaft is connected, the motor shaft is directly extended into the coupling, and then the screw is locked on the side. If the direct connection type is used, the p…

The difference between ordinary reducer and planetary reducer

Planetary reducer is generally used for transmission equipment with low speed and high torque. The reducer's function is to reduce the speed and increase the output torque. The output torque ratio is multiplied by the click output speed ratio, but attention should be paid to not exceed the rated output torque of the reducer. The planetary reducer also reduces the inertia of the load.

Servo reducer has the advantages of compact structure, small backhaul clearance, high accuracy, long service life and large rated output torque. However, the main feature of harmonic reducer with slightly expensive price is that it uses flexible components to control elastic deformation to drive motion and power. It has small volume and high precision, but its disadvantage is that flexible wheels have limited life. Shock resistance, rigidity is worse than metal parts. The input speed should not be too high.

Common types of reducers are worm gear and worm gear reducers, whose main characteristics are r…

Final Heat Treatment of Reducer Gears

In the operation of the reducer, there is also a need for professional personnel to take care of, so as to ensure that equipment in the use of the process can get the best help. I believe that with these guarantees, the efficiency of the whole work can be significantly improved.

The final heat treatment of gear reducer adopts high frequency quenching which makes the deformation of the part smaller.

The surface obtained after high frequency quenching has high strength, hardness, wear resistance and fatigue limit, while the core still maintains enough plasticity and toughness. In order to reduce the deformation of reducer, low quenching temperature and short heating time, uniform heating and slow cooling should be adopted for high frequency quenching of tooth surface.
