Abstract:Compared with other reducers, the harmonic reducer has the advantages of high precision, high torque, high rigidity, high transmission efficiency, etc., but the working principle of the harmonic reducer also determines that it has many shortcomings

harmonic reducerCompared with other reducers, it has the advantages of high precision, high torque, high rigidity, high transmission efficiency, etc.harmonic reducerThe working principle also determines that it has many shortcomings. In order to effectively avoid the possibility of vibration and abnormal noise of the harmonic reducer during operation due to errors during assembly. Please strictly observe the following when assemblingMatters needing attention in assembly of harmonic reducerImplement assembly.

 

Considerations for 1. wave generators

1. Please avoid the wave generator when assemblingBearingExcessive force is applied to the area. The insertion can be performed smoothly by rotating the wave generator.

2. When using a wave generator without an Oldham coupling structure, please pay special attention to control the influence of center offset and skew within the recommended value.

Precautions for 2. rigid wheels

1. Confirm whether the flatness of the installation surface is good and whether there is any skew.

2. Confirm whether the screw hole is bulged, there is residual burr or foreign matter is engaged.

3. Confirm whether chamfering and avoidance processing have been performed on the shell assembly part to avoid interference with the rigid wheel.

4. When the rigid wheel is assembled to the shell, confirm whether it can rotate and whether there is interference and clamping in some parts.

5. When inserting the bolt into the bolt hole for installation, confirm whether the position of the bolt hole is correct and whether the bolt is in contact with the rigid wheel due to the skew processing of the bolt hole, which makes the bolt rotate heavy.

6. Please do not tighten the bolts at one time according to the specified torque. Tighten temporarily with approximately 1/2 of the specified torque before tightening to the specified torque. In addition, usually tighten the bolts in diagonal order.

7. Pinning to the rigid wheel may cause low rotation accuracy, so please avoid it as much as possible.

Precautions for 3. the flexspline

1. Confirm whether the flatness of the installation surface is good and whether there is any skew.

2. Confirm whether the screw hole is bulged, there is residual burr or foreign matter is engaged.

3. Confirm whether the shell assembly part is chamfered and avoided to avoid interference with the flexspline.

4. When inserting the bolt into the bolt hole for installation, confirm whether the position of the bolt hole is correct and whether the bolt is in contact with the flexspline due to the skew processing of the bolt hole, which makes the bolt rotate heavy.

5. Please do not tighten the bolts at one time according to the specified torque. Tighten temporarily with approximately 1/2 of the specified torque before tightening to the specified torque. In addition, usually tighten the bolts in diagonal order.

6. Confirm whether there is extreme one-sided engagement when combined with rigid wheel. When a one-sided offset occurs, it may be due to a center offset or skew of the two components.

4. other considerations

1. The harmonic reducer must be installed in a sufficiently clean environment, and no foreign matter can enter the reducer during the installation process, so as to avoid damage to the reducer during use!

2. Please make sure that the gear surface and flexible bearing parts of the reducer are always fully lubricated.

3. After installing the wave generator, please make sure that the engagement between the flexible wheel and the rigid wheel is 180 ° symmetrical. If it deviates to one side, it will cause abnormal vibration and damage the flexspline.

4. After the installation is completed, clear the operation at low speed (100rpm). If there is abnormal vibration or abnormal noise, please stop immediately, recheck whether the installation is correct or contact our company to avoid incorrect installationReducerof damage.

 

Since the harmonic reducer is a high-precision component, please strictly follow the installation instructions during assembly to avoid abnormal harmonic reducer and cause more serious consequences.
