What are the advantages and disadvantages of the lubrication system for KA77-20-YEJ3-M1 gear reducer

The advantages of the lubrication system for KA77-20-YEJ3-M1 gear reducer are as follows:

1. Minimalist structure, extremely low failure rate, and low maintenance cost

No external vulnerable parts such as oil pumps, pipelines, valves, etc., relying solely on self operation to supply oil, without power failure, pipeline blockage, oil leakage and other problems; Only regular oil changes and oil level checks are required for daily use, without professional maintenance, suitable for low-cost operation and maintenance needs of small and medium-sized reducers (KA77)

2. Comprehensive lubrication coverage, compatible with the transmission structure of this model

Splashing oil can accurately cover the meshing surface of bevel gears and helical gears. The oil slinger ring, combined with the oil guide groove, can provide comprehensive oil supply to the input shaft, intermediate shaft, and output shaft bearings, while also taking into account the lubrication of the shaft shoulder and oil seal lip. It is compatible with the KA77 compact transmission structure and has no lubrication dead corners

3. Adapt to the start stop working conditions of YEJ3KW brake motor to avoid dry friction

At the moment of braking start stop, the oil in the oil tank can be quickly lifted up by the gears, and the meshing surface and bearings can quickly form an oil film to avoid dry friction during start stop; No external system delay, start stop response does not affect lubrication, suitable for frequent braking needs of YEJ motors

4. No additional power consumption, energy-saving and compatible with 3KW low-power motor

No need for external lubrication motor, driven by the gearbox itself for lubrication, no additional energy consumption, no increase in YEJ3KW motor load, suitable for energy-saving needs of low-power models

5. Reliable sealing and low risk of oil leakage

No external pipeline joints, relying solely on shaft end oil seals and box seals, with few sealing points; Oil supply without pressure, oil flows back by gravity, without leakage due to high pressure, suitable for the sealing requirements of M1 flange installation

6. Good heat dissipation adaptability and stable oil temperature

The casing serves as both an oil storage chamber and a heat dissipation body. The oil circulation relies on the natural heat dissipation of the casing wall. This model has a reduction ratio of 20, with minimal oil mixing loss during operation and less risk of abnormal oil temperature rise. Under normal operating conditions, the oil temperature can be stable at 40-70 ℃
