Advantages of choosing SR brand for K series + R series combined gear units:
1.Operating conditions of K+R series combined gear units: ambient temperature -40°C to 50°C (when starting below 0°C, the lubricating oil needs to be heated to above 0°C or antifreeze lubricating oil is used), the input speed is not more than 2800 rpm, Can be used for forward and reverse, no industry restrictions.
2.Performanceof K+R series combined gear units: This variable frequency reducer motor uses a serialized and modular design, with a wide range of transmission ratio, fine division, high transmission efficiency, low energy consumption, superior performance, and high-precision grinding of gears Gear grinding processing, stable transmission, low noise, large carrying capacity, long life, exquisite design, small size, easy installation, wide range of uses, diverse installation methods, suitable for all-round installation configuration, and can realize R series reducer double connection Body combination, suitable for special low-speed applications.
3.Transmission efficiency of K+R series combined gear units: high-precision gears, oil seals, bearings are used to effectively reduce friction, and the small path of gear transmission can reach 97%. In some installation methods, the input gear is completely immersed in lubricating oil In the case of large frame size and high input speed, oil churning losses must be considered.
4.Parts materialsof K+R series combined gear units: gearbox: HT250 high-strength cast iron, shot-type inner cavity, effectively reducing part wear gear; 20CrMo high-quality alloy steel, carbon-nitrogen treatment(maintain tooth surface hardness HRC60 after fine grinding ) Flat key: 45 steel, surface hardness HRC50.
