Introduction Of Sew Reducer
1.sew introduction
German SEW Group was established in 1931 and is located in Bruchsal, Baden-Württemberg, Germany. It is a multinational international group specializing in the production of various series of motors, reducers and frequency conversion control equipment. SEW Group has the most advanced production equipment in the world, is the world’s highest level and most advanced technology multinational company in the same industry, and its products are sold all over the world. Set up 10 manufacturing centers, 58 assembly plants and more than 200 sales and service offices around the world, covering five continents and almost all industrialized countries, which can provide customers all over the world with high-quality products and quality services quickly and easily. .
2. Features of SEW reducer
(1) Space saving, reliable and durable, high overload capacity, power up to 132KW;
(2) Low energy consumption, superior performance, and efficiency as high as 95% or more;
(3) Low vibration, low noise and high energy saving;
(4) Use high-quality forged steel material, rigid cast iron box, and the gear surface has undergone high frequency heat treatment;
(5) After precision machining to ensure shaft parallelism and positioning bearing requirements, the reducer forming the helical gear transmission assembly is equipped with various types of motors, combined into a mechatronics, which fully guarantees the quality characteristics of the product.
3. Product structure characteristics of SEW reducer
(1) Highly modular design: It can be easily equipped with various types of motors or other power inputs. The same model can be equipped with motors of multiple powers. It is easy to realize the combined connection between various models.
(2) Transmission ratio: fine division and wide range. Combined models can form a large transmission ratio, that is, output extremely low speed.
(3) Installation form: The installation position is not restricted.
(4) High strength and small size: the box body is made of high-strength cast iron. The gears and gear shafts adopt the gas carburizing quenching and fine grinding process, so the load capacity per unit volume is high.
(5) Long service life: Under the conditions of correct model selection (including selection of appropriate usage coefficient) and normal use and maintenance, the service life of main parts (except for wearing parts) is generally not less than 20,000 hours. The wearing parts include lubricating oil, oil seals and bearings.
(6) Low noise: The main parts and components have been precision processed, assembled and tested, so the reducer has low noise.
(7) High efficiency: the efficiency of a single model is not less than 95%.
(8) It can bear larger radial load.
(9) It can withstand an axial load not greater than 15% of the radial force.
