What gear oil is used for SEW reducer?

SEW reducer uses No. 220-680 gear oil. The gear oil is mainly used to lubricate gears and bearings, prevent wear and rust, and help gears to dissipate heat.

Automotive gear oil is used in gear transmission mechanisms such as automotive steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oils can be used for lubrication, anti-wear, cooling, heat dissipation, anti-corrosion, anti-rust, cleaning and lowering of gears. Surface impact and noise play an important role.

Gear oil is an important lubricating oil prepared by adding petroleum lubricating oil base oil or synthetic lubricating oil, adding extreme pressure antiwear agent and oiliness agent.Used in various gear transmissions to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life and improve the efficiency of power transmission.The hyperbolic tooth surface load is as high as 2942MPa. In order to prevent the tooth surface from being worn and scratched by oil film rupture, extreme pressure antiwear agents are often added to the gear oil.

Precautions:

1. In order to achieve a particularly low output speed, it can be realized by connecting two gear reducers.When using this transmission scheme, the power of the configurable motor must depend on the limit output torque of the reducer, and the output torque of the reducer cannot be calculated by the motor power.

2. When installing the transmission part on the SEW output shaft, it is not allowed to hit it with a hammer. Usually, use the assembly fixture and the internal thread of the shaft end to press the transmission part with bolts, otherwise it may cause damage to the internal parts of the reducer.It is best not to use rigid fixed couplings, because improper installation of such couplings will cause unnecessary external loads, resulting in early damage to the bearings.

3. The SEW 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 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 is driven by gears and sprockets, and the output shaft bears a large radial load, the reinforced type should be selected.
