Description
Technical field: the utility model relates to a kind of roller-way frequency control threephase asynchronous of electric product.Particularly be applied in the frequency conversion motor special that the metallurgical industry roller-way transmits.
Background technology: because this kind motor special environment for use is extremely abominable, locked-rotor torque, breakdown torque require high, locked rotor current is low, in design and manufacturing, many difficult points are arranged, present domestic prior art frequency conversion scope is little, and capacity motor is little, and degree of protection does not reach the operating mode needs, anti-harmonic voltage impact capacity difference turn-to-turn phenomenon is serious when mating with frequency converter, and this situation has limited the development of China's steel and iron industry.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of roller-way frequency control threephase asynchronous is provided, and has solved the problem that capacity motor is little, degree of protection does not reach the operating mode needs.The purpose of this utility model be achieved in that roller-way with the frequency control threephase asynchronous by: axle, protector, oiling device, support, stator, rotor, suspension ring, terminal box, internal bearing cover, bearing are formed.Rotor press-mounting is on axle, on the axle internal bearing cover and bearing and protector are housed, oiling device is installed on the front and rear cover, and stator is contained in the support, suspension ring and terminal box are installed in upper part of the frame, protector by: bearing end cover, oil sealing, throw rijng, holding screw are formed.Bearing end cover is installed on the end cap, and oil sealing is embedded in the bearing end cover, and throw rijng is fixed on the axle with holding screw, and it and bearing end cover form labyrinth seal.This product capacity is big, degree of protection is high, margin of temperature rise is big, be adapted at complicated rugged environment work, available frequency converter is as power supply, and speed adjustable range is wide, higher dielectric strength is arranged, overload capacity is strong, and frequently rotating is shock-resistant, rational in infrastructure, the profile fineness can be used for the frequency conversion motor special that the metallurgical industry roller-way transmits, and also can be used for other similar plant equipment.
