1, gear motor before installation precautions
Before installation, check the nameplate requirements on the gearbox motor to see if the power supply matches. Check that the gearbox motor and the gearbox are in good health. The requirements of the working environment should be in places free of oil, acid, alkali, harmful gases, steam, radioactivity and other substances.
2, when installing the drive on the output shaft, do not allow hammer tapping, usually using the assembly fixture and shaft end of the internal thread, with bolts to press the drive into, otherwise it may cause damage to the internal parts of the reducer. It is best not to use steel fixed couplings, because the couplings are not installed properly, will cause unnecessary external loading load, resulting in early damage to bearings, serious and even cause the output shaft to break.
3, the worm worm gear motor can not be on the reducer (self-locking) to apply a large reverse transmission load.
4, to use solvents to completely remove shaft extension, flanges, key surface preservatives, dirt, etc. , when removing should not let the solvent immersed in the oil seal, otherwise the solvent may damage the oil seal.
5, the installation basis of the gear motor should be strength, reliability of stiffness, vibration reduction, anti-torque base, bench until the support structure, and the foundation must be dry, and there must be no grease.
6, both the bottom of the box and the installation of french products in the installation of strict defense against each other.
7, the minimum performance level of the base spiral is 8.8.
8, the coupling between the gearbox machine is recommended to use an elastic coupling.
9, the input, output shaft assembly couplings, brakes, clutches, gear radial load of the force point should be as close to the shaft shoulder as possible.
10, there is a key hollow output shaft and the work machine shaft joint should be coated with anti-rust oil, loading should be easily pushed in or with a spiral pull in, and the rising tight disk hollow output shaft in one end should not oil any oil, grease, the other end can be coated with anti-rust oil.
11, the input, output shaft and primary motivation of the gearbox motor, the work machine shaft should be strictly in the coaxial, its requirements can reduce vibration to reduce noise, extend the life of the bearing, to ensure the normal operation of the gearbox motor.
12, in order to prevent accidents, so the rotating part should be in accordance with safety requirements to install a shield, cover.
13, to ensure that each gearbox should be properly installed, and to ensure smooth breathing. According to the provisions of the installation device to ensure that staff can easily approach the oil mark, gas plug, drain plug. After installation in place, the accuracy of the installation position should be thoroughly checked in order, the reliability of the fasteners pressed, after installation should be flexible rotation. The gearbox is lubricated with a splash of oil sink, and the user needs to remove the plug from the breather hole and replace it with a gas plug before running. According to different installation positions, and open the oil plug screw to check the height of the oil level line, from the oil plug to the lubricant from the oil plug screw hole overflow, screw on the oil plug to determine the correct, before the empty load test run, the time must not be less than 2 hours. The operation should be smooth, no shock, vibration, noise and oil leakage phenomenon, found abnormal should be eliminated in time.
14, when the torque needs to be installed, should be installed in a state of mutual freedom.
15, the installation lock must be firm and reliable, not in the work of displacement.
16. Be sure to install a grounding device to prevent electric shock.
