Service factor
The service factor (f.s.) depends on the operating conditions the gearbox is subjected to. Following parameters need to be takes select the right service factor:
–type of load of the operating machine A-B-C
–length of daily operating time: hours/day (Δ)
–start-up frequency: starts/hour (*)
Type of load: A- uniform, fa≤0.3
B-moderate shocks, fa≤3
C-heavy shocks, fa≤ New DGM6010 24V Brushless Exoskeleton Four-Legged Robot Arm High Torque Two Stage Planetary Reducer Gear Motor 10

Installation notes
–The mounting on the machine must be stable to avoid any vibration.
–Check the correct direction of rotation of the reduction unit output shaft before fitting the unit to the machine.
–In the case of particularly lengthy of storage (4-6 months) if the oil seal is not immersed in the lubricant inside recommended changing it since the rubber could stick to the shaft or even has lost the elasticity it needs to function prober.
–For a shaft mounting, for reduction units with a hollow output shafts, use the torque arms motion clinic can supply. If it is make sure that the constraint is axially free and with such as play as to ensure free movement to the reduction unit.
–Whenever possible, protect the reduction unit against solar radiation and bad weather.
–Ensure the motor cools correctly by assuring good passage of air from the fan side.
–In the case of ambient temperatures<-5°C and >+40°C contact motion clinic.
–The various parts (pulleys, gear wheels, couplings, shaft, etc.) must be mounted on the solid or hollow shafts using special holes or other systems that anyhow ensure correct operation with-out risking damage to the bearing or external parts of the unit.
–Painting must definitely not go over rubber parts and the holes on the breather plugs, if there are any.
–Taking out the seal embolism of the oil hole.
–Check the height of the oil level.
–Supposing the gear units have not coupled with the motor, please pay attention to the following items to make sure rightly connection. To mounting as the B5, B1.
–Check the whether the tolerance between the shaft and motor flange fit for the essential standard.
–Washing the dirt and the paint on the surfaces of the shaft, center bore and the flange.
–Mounting avoid the gear unit incur strength.
–Check the position and the deviation of the motor key slot.
–Lubricate the surface in contact to avoid seizure or oxidation.
–Starting must take place gradually, Nema 17 Flange Output Planetary Gearbox Universal Speed Reducer without immediately applying the maximum load.
–When there are parts objects or materials under the motor drive that can be damaged by even limited spillage of oil, special should be fitted.
