Precautions for installation and use of reducer; use, maintenance and precautions of gear reducer, etc. Check out the details below
Tell.
1. Installation of shaft-mounted reducer
(1) Installation relationship between reducer and working machine
In order to avoid deflection of the main shaft of the working machine and additional force on the bearing of the reducer, the distance between the reducer and the working machine must not affect the normal operation.
Under normal working conditions, it should be as small as possible, and its value is 5-10mm.
(2) Connection between reducer and working machine
The reducer is directly mounted on the main shaft of the working machine. When the reducer is running, the reaction torque acting on the reducer box is mounted on the reducer.
The counter-moment bracket on the chassis may be balanced by other methods. The machine directly matches, and the other end is connected to the fixed bracket.
(3) Installation of reaction moment bracket
The counter-moment bracket should be installed on the side of the working machine facing the reducer to reduce the bending moment added to the working machine shaft. Reaction moment bracket
The bushing connected to the fixed support uses elastomers such as rubber to prevent deflection and absorb the generated torque fluctuations.
2. Use, maintenance and precautions of gear reducer
(1) When disassembling and assembling the reducer, try to avoid hammering to avoid damaging normal parts.
(2) If oil leakage is found in the shaft extension or connection during use, the skeleton oil seal and other seals should be replaced in time.
(3) The reducer uses 460# medium-load industrial gear oil, and the working environment temperature is 0~40℃.
(4) After the first 100 hours of use, the inner cavity should be cleaned and replaced with new gear oil, and the oil should be changed every 2,000 hours thereafter.
3. Precautions for installation and use of reducer
(1) The reducer should be firmly installed on a stable and horizontal foundation or base, the oil in the oil drain tank should be able to be drained, and the cooling air should circulate smoothly
. The foundation is unreliable, causing vibration and noise during operation, and causing damage to bearings and gears. When the transmission coupling has protrusions or adopts
When gears and sprockets are driven, protective devices should be considered. When the output shaft bears a large radial load, a reinforced type should be selected.
(2) Install the device according to regulations to ensure that workers can easily approach the oil mark, vent plug, and oil drain plug. After installation is in place, the order should be
Comprehensively check the accuracy of the installation position and the reliability of the compression of each fastener. It should be able to rotate flexibly after installation. The reducer adopts oil pool splash
Lubrication, the user needs to remove the screw plug of the vent hole and replace it with the vent plug before operation. Press different installation positions and open the oil level plug screw
Check the height of the oil level line, add oil from the oil level plug until the lubricating oil overflows from the screw hole of the oil level plug, screw on the oil level plug and make sure it is correct before proceeding.
No-load test operation can be carried out, and the time shall not be less than 2 hours. The operation should be smooth, without impact, vibration, noise or oil leakage. If any abnormality is found,
It should always be eliminated in time.
(3) When installing the reducer, attention should be paid to the alignment of the transmission center axis, and the error shall not be greater than the compensation amount of the coupling used. Good for Zhongzhong
It is best to extend the service life and obtain ideal transmission efficiency.
(4) When installing the transmission part on the output shaft, it is not allowed to hit it with a hammer. Usually, the assembly clamp and the internal thread of the shaft end are used, and the bolts are used to secure the transmission part.
The transmission parts must be pressed in, otherwise the internal parts of the reducer may be damaged. It is best not to use rigid fixed couplings because this type of coupling
Improper installation of the device will cause unnecessary external loads, causing early damage to the bearings, and even causing the output shaft to break in severe cases.
