Precautions for installation and use of reducer

reducer is a common power transmission mechanism, which is applied in various mechanical transmission systems. The installation and use of reducer is directly related to the operation effect of reducer, and it should comply with technical specifications and standards. For the reasonable installation and use of reducer, the following matters should be paid attention to

1. When installing the reducer, pay special attention to the alignment of the transmission center axis, and the alignment error cannot exceed the use compensation of the coupling used by the reducer. After the reducer is aligned as required, it can obtain more ideal transmission effect and longer service life

2. When installing the transmission parts on the output shaft of the reducer, we must pay attention to the sensitive characteristics of the operating equipment. It is forbidden to use hammers and other tools for rough installation. It is best to use the assembly fixture and the internal thread of the end shaft for installation, and press the transmission parts into the reducer with the screw in force of the bolts, so as to protect the internal parts of the reducer from damage

3. There are many types of couplings used in the reducer, but it is best not to use rigid fixed couplings. The installation of such couplings is difficult, especially in the field of medical devices or automobiles. Once improperly installed, the load will be increased, which is easy to cause bearing damage and even output shaft fracture

4. The fixing of the reducer is very important to ensure stability and firmness. Generally speaking, we should install the reducer on a horizontal foundation or base. At the same time, the oil in the oil drain tank should be drained and the cooling air circulation should be smooth. If the reducer is not fixed well and the foundation is not reliable, it will cause, vibration and other phenomena, and will also cause unnecessary damage to the bearings and gears

5. When necessary, the transmission coupling of the reducer (7) turn the hand wheel to lower the test piece, and then move the test piece Carry out new experiments according to the above steps (2) - (6); Protective devices should be installed, such as protrusions on the connecting pieces or the use of gears, sprocket drives, etc. if the radial load borne by the output shaft is large, the reinforced type should also be selected

6. The installation position of the reducer should ensure the operation of the staff, including the convenient access to the vernier, vent plug, oil drain plug and other positions. After the installation of the reducer, the inspectors should comprehensively check the accuracy of the installation position in order to determine the reliability of each fastener

7. Before the reducer is operated, it is also necessary to prepare for operation, remove the vent plug of the oil pool and replace it with a vent plug, open the oil level plug screw to check the oil line height, add lubricating oil beyond the oil level plug screw until the hole overflows, then screw on the oil level plug and confirm that it is correct, and then start the trial operation

8. The trial operation time of the reducer shall not be less than two hours. The standard for normal operation is that the reducer operates smoothly, without vibration, noise, leakage and impact. If there are abnormal conditions, it shall be discharged in time, especially in the automobile manufacturing industry, medical supplies industry and consumer electronics industry
