The installation of the shaft-mounted reducer and the precautions and installation of the reducer.The following Shanghai reducer describes the installation of the shaft-mounted reducer; the precautions for the installation and use of the reducer; the use, maintenance and precautions of the gear reducer.Take a look at the detailed description below.
XNUMX. Installation of shaft-mounted reducer
(XNUMX) Installation relationship between reducer and working machine
In order to avoid the deflection of the main shaft of the working machine and the additional force on the bearing of the reducer, the distance between the reducer and the working machine should be as small as possible without affecting the normal working conditions, and its value is 5-10mm.
(XNUMX) Connection of reducer and working machine
The reducer is directly sleeved on the main shaft of the working machine. When the reducer is running, the reaction torque acting on the reducer case body is balanced by the reaction torque bracket installed on the reducer case body or other methods.The machine is directly matched, and the other end is connected with the fixed bracket.
(XNUMX) Installation of anti-moment bracket
The counter-moment support should be installed on the side of the working machine that the reducer faces to reduce the bending moment attached to the working machine shaft.The counter-torque bracket and the shaft sleeve of the fixed supporting connection end use rubber and other elastic bodies to prevent deflection and absorb the generated torque fluctuations.
XNUMX. Use, maintenance and precautions of gear reducer
(XNUMX) When disassembling the reducer, try to avoid hammering to avoid damage to normal parts.
(XNUMX) If oil leakage is found in the shaft extension or joint during use, the skeleton oil seal and other seals should be replaced in time.
(460) The reducer adopts 0# medium-duty industrial gear oil, and the working environment temperature is 40-XNUMX℃.
(100) After the first 2000 hours of use, the inner cavity should be cleaned and replaced with new gear oil, and the oil should be changed every XNUMX hours.
XNUMX. Precautions for installation and use of reducer
(XNUMX) The reducer should be firmly installed on a stable level foundation or base, the oil in the oil drain groove should be able to be drained, and the cooling air circulation should be smooth.The foundation is unreliable, which will cause vibration and noise during operation, and cause damage to bearings and gears.When the transmission coupling has protrusions or adopts gears or sprockets for transmission, consider installing protective devices. When the output shaft bears a large radial load, a reinforced type should be selected.
(2) Install the device according to the regulations to ensure that the staff can easily approach the oil mark, vent plug and oil drain plug.After the installation is in place, the accuracy of the installation position should be comprehensively checked in order, the reliability of the pressing of the fasteners, and the flexible rotation should be possible after installation.The reducer adopts oil pool splash lubrication. The user needs to remove the screw plug of the vent hole and replace the vent plug before operation.Check the height of the oil level line by opening the oil level plug screw according to different installation positions. Add oil from the oil level plug until the lubricating oil overflows from the oil level plug screw hole. Load trial run, the time shall not be less than XNUMX hours.The operation should be stable, and there should be no shock, vibration, noise and oil leakage. Any abnormality should be eliminated in time.
(XNUMX) When installing the reducer, attention should be paid to the centering of the transmission center axis, and the error should not be greater than the compensation amount of the coupling used.Good alignment can prolong the service life and obtain ideal transmission efficiency.
(XNUMX) When installing the transmission parts on the output shaft, it is not allowed to hit with a hammer. Usually, use the assembly fixture and the internal thread of the shaft end to press the transmission parts in with bolts, otherwise it may cause damage to the internal parts of the reducer.It is best not to use rigid fixed coupling, because improper installation of this type of coupling will cause unnecessary external load, which will cause early damage to the bearing, or even break the output shaft in severe cases. |
