German the SEW group was founded in 1931, is located in Bruchsal Germany baden-wurttemberg, is specialized in producing various series of motor, reducer and frequency conversion control device of transnational international group. The SEW group owns the world's most advanced production equipment, is the world's highest, the most advanced technology in the industry of multinational company, product marketing all over the world. Set up 10 in all over the world manufacturing center, 58 assembly plant and more than 200 sales and service offices throughout the world on five continents and almost all industrialized countries, is fast and convenient to customers around the world to provide high quality products and quality service.
Since entering China in 1995, the SEW company obtained the swift and violent development, has been in tianjin, suzhou, guangzhou, shenyang and other regions to establish manufacturing center and assembly base business covers a variety of industries and national key project, for the development of China's power transmission technology has made a great contribution.
Santasalo hang the SEW brand is because of its popularization in China is not enough, signed the agreement with the SEW in 99, the SEW is responsible for promoting its products, premise must hang the logo. Later two cooperation burst, M series and other large industrial reducer is the SEW purchased from santasalo technology. Industrial gear reducer product M, MC, ML series.

The SEW gear motor is designed on the basis of the module combination system, there are very many motor combination, installation position and structure scheme. The SEW module combination system allows reducer and combination of the following components:
- synchronous motor with a constant field synthetic gear motor servo unit;
- work with dangerous environment type ac squirrel cage motor combination;
- combined with dc motor;
- with VARIBLOC® And VARIMOT® The transmission gear motor stepless speed regulation.

Matters needing attention
1, to meet the special low output speed, can through the two gear speed reducer connected way to implement. When using the transmission scheme, configurable motor power must rely on the limit of the speed reducer output torque, rather than through the motor power to calculate the output torque reducer.
2, when the SEW the output shaft is installed on a not allow to use hammer, usually using the assembly fixture and shaft within the thread, press the transmission parts bolted into, otherwise may cause reducer damage to internal components. Had better not adopt fixed rigidity coupling, because of the coupling installed improperly, can cause unnecessary loads, so that the cause of bearing early damage, serious when even cause output shaft fracture.
3, the SEW reducer should be firmly installed in a stable level or the base, the base of row should be able to rule out the oil tank and the cooling air circulation fluid. Based on unreliable, running can cause vibration and noise, and prompted bearing and gear damage. When the connection with protrusions or transmission gear, chain wheel drive, the installation of protective device should be taken into account, the output shaft under high radial load, should choose enhanced.
4, in accordance with the provisions, the installation of the devices to ensure workers can conveniently close to the oil standard, ventilation, discharge of oil seal. After installation in place, should be in order fully check the accuracy of the installation position, various fasteners, the reliability of compaction, after installation should be able to turn flexibly. Reducer adopts splash lubrication oil pool, before running the user needs to get off the vent plug, change into air plug. According to the different installation position, and open the oil level check the height of the oil level line plug screw, gas from the oil plug to lubricating oil from the oil level overflow plug screw hole, twist after confirmed and correct, put a plug before being no-load test run, time shall not be less than 2 hours. Running should be smooth, without shock, vibration, noise and oil leakage phenomenon, found exceptions should be ruled out in time. Should check the oil level again, after a certain period in order to prevent the casing may cause leakage, such as environmental temperature too high or too low, can change the brand of lubricating oil.
The installation
1, the SEW reducer and join the SEW machine work on machine spindle reducer directly suit at work, when running the SEW reducer, effect on the SEW reducer casing of torque, and installed on the SEW reducer casing of torque to balance stent or by other methods. Machine suitable, directly at the other end with the fixed bracket.
2 shows the installation of the torque, the torque should be installed in the reducer side near the working machine, and to reduce the additional bending moment on the working machine shaft. Counter torque support and fixed support join the collar use rubber elastomer, to prevent deflection and absorb the torque ripple.
3, the installation of the SEW reducer with the SEW machine working relationship in order to avoid working machine spindle deflection and generate additional force on reducer bearing, the SEW reducer and the distance between the work machine, in does not affect the normal working conditions should be small, as far as possible with a value of 5-10 mm.
Folding editing this section inspection maintenance
When new operational speed reducer, the factory has injection of GB/T5903 L - CKC100 ~ L - CKC220 extreme pressure industrial gear oil, in 200 ~ 300 hours after operation, the first oil change should be made, in the later use should periodically check the oil quality, to mix impurities or metamorphic oil must be timely replacement. In general, the SEW reducer for long-term continuous work, according to run 5000 hours, or once a year to replace the new oil, stop using the speed reducer for a long time, should also be replaced before running again new oil reducer should join the same as the original brand of oil, may not be used with different type of oil phase, the same brand but different viscosity oil allow mix. Oil change wait for reducer cooled down when no burning danger, but should still keep warm, because completely cooled, the oil viscosity increase, oil drain. Note: to cut off the transmission power, prevent inadvertently electricity! When oil was found in the work of all [rises more than 80 ℃ or oil pool temperature over 100 ℃ and produce the phenomenon such as abnormal noise should stop using, check the reason, have to troubleshoot, after oil change, may continue to operate. Users should have the use of reasonable maintenance rules and regulations, the reducer operation situation and the problems found during the inspection should be done carefully record, the above regulations must be strictly implemented. Five, the selection of lubricating oil the SEW reducer proper viscosity lubricating oil must be added before putting into operation, to reduce friction between the gear, meet the high load and impact load, the speed reducer can give full play to its function. ?? First used around 200 hours, must put out the lubricating oil, rinse, then rejoined the new oil to the center, oil level is too high or too low can lead to abnormal operating temperature.
