[GM] gear reducer related knowledge
Universal gear gear Material:
General manufacturing gear reducer commonly used steel has quenched and tempered steel, hardened steel, carburizing steel, and nitriding steel. Slightly lower than the strength of forged steel, commonly used in a larger size gear; the poor mechanical properties of gray cast iron, can be used for light load open gear drive; ductile iron may be partially replaced by steel universal gear reducer; plastic universal gear reducer used for light load and low noise requirements of local, paired with good thermal conductivity gear generally generic steel gear reducer. Future common gear reducer forward overloading, high speed, high precision and high efficiency, the direction of development, and strive to small size, light weight, long life, and economically viable.
Universal gear gear maintenance:
A universal gear reducer using # 460 in load industrial gear oil, the working temperature of 0 ~ 40 ℃.
Second, after the first use of general-purpose gear reducer 100 hours should be replaced with a new cavity clean gear oil after an oil change once every 2000 hours.
Third, the dismantling reducer should avoid hammering to avoid damage to normal parts.
Fourth, if found to have a shaft extension or joints oil leakage, should be replaced skeleton oil seals and other use.
