How to choose the lubricating oil viscosity of the reducerWe usually inject a certain amount of lubricating oil into the machine before using the reducer. The injected lubricating oil has very strict requirements for viscosity. Therefore, viscosity is an important physical and chemical index of gear oil. The viscosity of the oil is selected correctly. , It will reduce the internal friction of the lubricating oil, thereby reducing the wear on the gear surface of the reducer and the transmission noise, vibration, etc. Then, what is the appropriate viscosity of the lubricating oil? The reducer manufacturer introduced the following to us. 1. The viscosity of the lubricating oil of the reducer is mainly realized by the base oil and the viscosity index improver. Among them, the viscosity of the base oil is related to the molecular structure and molecular weight. The larger the average molecular weight, the greater the viscosity of the oil. 2. A good viscous agent should have high viscosity increasing ability, good shear stability, good low temperature performance and thermal oxidation stability. 3. For lubricating oils of the same viscosity grade, if you choose non-refined base oils and poor viscosity indexing agents, although they can reach a certain viscosity standard after blending, they will have viscosity-temperature properties and shear stability. Poor, the same can not reach the expected life cycle. In actual production, we can select the lubricating oil viscosity of the reducer according to the above method. For low-speed and heavy-duty reducers, we should choose high-quality high-grade lubricating oils, and try to avoid using non-refined base oils or poor viscous agents Because its base oil and viscous agent are better, the greater the viscosity of the gear oil, the stronger the protection against various damages to the tooth surface, and the smaller the mechanical wear.CAMEL Transmission Machinery Factory is a professional supplier,distributor and manufacturer of gear reducers and related accesories. including rotary reducer,worm gearbox, servo-gearbox, planetary gearboxes,planetary gear reducer, helical gear reducers,planetary gearbox,right angle gear reducer, gear reduction,gear motors, electrical motors,DC motors, DC gear motor,dc gearedmotors,AC gear motor,AC motors, servo motors,servomotor, bearings, spur gear,helical gear,bevel gear,worm gear,planetary gear, couplings, oil seals, belts, chains, etc.If you have any need, please feel free to contact CAMEL:
