Reducer is a common power transmission mechanism that is applied in various mechanical transmission systems. The installation and use of the reducer are directly related to its operational effectiveness and must comply with technical specifications and standards. How to install and use the reducer reasonably, pay attention to the following points.
Precautions before installation:
- The installation shaft of this machine should be cleaned before use. And check if there are any scratches or dirt on the installation shaft. If there are, they should be completely cleaned.
- The operating temperature of the reducer is 0-40 ℃.
- Check whether the fit size of the hole (or shaft) connected to the reducer meets the requirements, and the tolerance of the hole should be H7 (the tolerance of the shaft should be H6).
Before use, the blockage at the highest position should be replaced with an exhaust plug to ensure that the gas inside the gearbox is discharged during operation.
Precautions during installation:
- When installing the reducer, special attention should be paid to the alignment of the transmission center axis, and the alignment error should not exceed the compensation amount of the coupling used in the reducer. After the reducer is aligned according to the requirements, it can achieve more ideal transmission effect and longer service life.
- When installing the transmission components on the output shaft of the reducer, attention must be paid to gentle operation. It is forbidden to use tools such as hammers for rough installation. It is best to use assembly fixtures and internal threads of the end shaft for installation, and press the transmission components into the reducer with the force of bolts to protect the internal parts of the reducer from damage.
- The fixation of the gearbox is very important to ensure stability and firmness. Generally speaking, we should install the gearbox on a horizontal foundation or base, and the oil in the oil drain groove should be able to be discharged, and the cooling air circulation should be smooth. Poor fixation and unreliable foundation of the reducer can lead to phenomena such as vibration and unnecessary damage to the bearings and gears
- When necessary, protective devices should be installed on the transmission connecting parts of the reducer, such as protrusions on the connecting parts or the use of gears, sprockets, etc. If the output shaft bears a large radial load, a reinforced type should also be selected.
- The reducer can only be installed on flat, shock-absorbing, and torsion resistant support structures.
Under no circumstances should a hammer be used to knock pulleys, couplings, small gears, or sprockets into the output shaft, as this can damage the bearings and shaft.
