Description
Technical field
The utility model belongs to cement motor apparatus field, and in particular to a kind of Vertical Mill synchronous electricity of half directly-drive permanent magnet
Motivation.
Background technology
Traditional cement vertical mill dragging system mainly adds gear mechanical gear box group by wound three-phase asynchronous motor
Into, gearratio is so increased, using the fault rate that deceleration system is improved in the case of multi-change speed, and the later stage
The maintenance of gearbox and maintenance cost are of a relatively high, in addition also to add soft starting device and low speed cranking system, not only open
Dynamic resistance increases, and vibration and noise be not also small, and the weight of complete equipment also increased.As cement vertical mill is in cement row
The extensive use of industry, user propose higher requirement to equipment, should improve system effectiveness reduce again worker maintenance,
Repair density.
The content of the invention
The utility model purpose provides a kind of Vertical Mill half directly-drive permanent magnet synchronous motor, and solve the above problems deficiency, real
Show the Highgrade integration with deceleration system, mitigated weight, reduce the effect of noise.
The utility model is achieved in the following ways Vertical Mill half directly-drive permanent magnet synchronous motor, and it is fixed to be provided with support
Son and rotor, armature spindle are separately mounted on the upper end cover and bottom end cover of support by bearing, and the both ends of armature spindle are all provided with hairiness
Felt rug is sealed.Described support uses water jacket cooling system structure, and small radiating ribs are welded between water channel；Described upper end cover
It is integral type structure with thrust box, is provided with fluid oil in described thrust box, motor oil circuit is directly derived from thrust axis
Hold the fluid oil in case.Upper end cover is upside-down triangle shape and hypotenuse is stepped；Thrust bearing is installed on thrust bearing
In case, the upper end of thrust bearing supports runner plate, and upper sealing ring is provided between runner plate and thrust box.Reducing gear is arranged on
In the upper end cover of upside-down triangle shape, and the upper end of armature spindle is connected with reducing gear；Described rotor is provided with permanent magnets,
Fan is housed equipped with the copper bar and end ring for realizing self-starting function, motor internal rotor tip on the outer surface of permanent magnets.
The stator punching of described stator uses cold-reduced silicon sheet.
The beneficial effects of the utility model are that have developed the special half directly-drive permanent magnet synchronous motor of totally-enclosed cement vertical mill,
Variable frequency starting is not needed in control, self-starting can be achieved, met after startup by primary speed-down system needed for cement vertical mill
The requirement of low-speed big, the efficiency of system is improved, reduce the maintenance, repair intensity of worker, and motor is totally-enclosed
Structure, further ensure the reliability of motor.
