Abstract
The utility model discloses a cast copper rotor goes heavily balanced loop to construct, including rotor shaft, balanced ring, first cast copper rotor end ring, second cast copper rotor end ring and rotor core, the rotor shaft on be equipped with balanced ring, first cast copper rotor end ring, rotor core and second cast copper rotor end ring in proper order. The utility model provides a pair of cast copper rotor goes heavily balanced loop to construct adopts the structure that increases balanced ring, has simplified cast copper rotor mould structure, makes cast copper rotor yield improve, has reduced the quantity of noble metal copper, practices thrift the cost.
Description
Technical field
The utility model belongs to motor technology field, is specifically related to a kind of copper casting rotor duplicate removal gimbal structure.
Background technology
Motor is a kind of equipment that electric energy is converted to mechanical energy, it is to utilize hot-wire coil to produce rotating excitation field and act on rotor to form magnetoelectricity dynamic rotation moment of torsion, motor is by using power supply difference to be divided into dc motor and ac motor, motor major part in power system is alternating current generator, can be synchronous motor or asynchronous machine, motor is mainly made up of stator and rotor, the direction of electrified wire stressed motion in magnetic field is relevant with magnetic induction line direction with the sense of current, motor operation principle is that magnetic field is to the stressed effect of electric current, motor is rotated.
Fine copper has excellent electric conductivity, its Conductivity Ratio aluminium is high by 40%, adopt copper rotor to replace aluminium matter motor rotor die-casting technology to be considered to improve one of optimal path in the technology of middle-size and small-size squirrel cage motor efficiency, therefore, just there is the copper bar of use soldering copper rotor to occur as far back as five sixties of 20th century, and being developed so far through decades, realize the technology of utilizing compression casting fine copper rotor, but also there is the problem of dynamic balance checking difficulty in copper casting rotor motor, the mode that conventional aluminium rotor balancing post increases the weight of cannot meet the requirement of copper casting rotor dynamic balance checking, on aluminium rotor electromotor, mode by shimming on rotor balancing post is carried out dynamic balancing calibration, adopt in this way dynamic balance checking on fine copper rotor time, because the density of copper is high, add weight very large, this just makes balance columns increase the weight of to meet the requirement of fine copper rotor calibration balance, simultaneously, because the use of balance columns not only makes mould structure complexity, and virtually make the fine copper die casting life-span greatly reduce.
Existing copper casting rotor balanced structure is to adopt copper casting rotor end ring to increase concaveconvex structure, thereby realizes the object of duplicate removal balance, makes like this copper casting rotor mould structure complexity, and copper consumption increases.
Utility model content
For prior art deficiency, a kind of copper casting rotor duplicate removal gimbal structure that the utility model provides adopts the structure that increases gimbal, has simplified copper casting rotor mould structure, and copper casting rotor yield rate is improved, and has reduced the consumption of noble metal copper, cost-saving.
For realizing utility model object, the utility model by the following technical solutions:
A kind of copper casting rotor duplicate removal gimbal structure, comprise armature spindle, gimbal, the first copper casting rotor end ring, the second copper casting rotor end ring and rotor core, on described armature spindle, be equipped with successively gimbal, the first copper casting rotor end ring, rotor core and the second copper casting rotor end ring, copper casting rotor replaces traditional cast-aluminum rotor, and motor efficiency is greatly improved, simultaneously, only need a gimbal just can make motor stable operation, reduce installation time, saved material, reduced costs.
Be preferably, described gimbal, the first copper casting rotor end ring, the second copper casting rotor end ring and rotor core respectively with armature spindle interference fit, in conjunction with firmly.
Be preferably, described gimbal is annular, and balance duplicate removal occurs on gimbal cylindrical, reduces the vibration of motor, has increased the stationarity of motor.
Be preferably, described gimbal adopts steel material to make, cost-saving.
A kind of copper casting rotor duplicate removal gimbal structure beneficial effect of the present utility model is: a kind of copper casting rotor duplicate removal gimbal structure that the utility model provides adopts the structure that increases gimbal, simplify copper casting rotor mould structure, copper casting rotor yield rate is improved, reduce the consumption of noble metal copper, cost-saving.
