Abstract
The utility model provides a large-scale vertical double-air-gap disc-type motor, belongs to the field of a motor device, and specifically relates to the large-scale vertical double-air-gap disc-type motor. The large-scale vertical double-air-gap disc-type motor comprises a shaft, a stator, a rotor, a front end cover and a back end cover. The large-scale vertical double-air-gap disc-type motor is characterized in that the large-scale vertical double-air-gap disc-type motor further comprises two annular connection ribs; the front end cover and the back end cover are respectively provided with a positioning ring slot; and the connection ribs are embedded in the positioning ring slots and are fixed through bolts. The stator comprises an upper stator and a lower stator. A stator core of the upper stator and a stator core of the lower stator are welded on the connection rib of the back end cover and the connection rib of the front end cover respectively. The design enables the installation and positioning of the stator to be more accurate; early-stage assembly and later-stage maintenance can be done conveniently; since the precise positioning of the stator, the stator and the rotor can be ensured a reasonable gap value, so that the case of motor burnt out due to the mutual friction of the stator and the rotor after the motor running for a while does not happen; the motor runs more stable; and the service life of the whole machine can be effectively prolonged.
Description
Technical field
The utility model belongs to motor device field, is specifically related to the two air gap disc type electric machines of a kind of large-scale vertical.
Background technology
The stator of common electric machine and rotor assembling mode are for being inside and outside set with, and air gap distribution is radially, and after therefore installing, processing quality is easy to ensure.And disc type electric machine is in order to obtain large torque, rotor diameter is large especially and axial dimension designs shortly especially, and its two stators and a rotor are to be respectively made up of disc type iron core, the two parallel installation, it is axial that air gap distributes, and the gap between stator and rotor is difficult for ensureing.The motor of vertical installation is subject to the condition restriction such as the strength of materials and process structure, is easy to occur that stator and rotor wipe phenomenon and the phenomenon of motor damage mutually in running.
Summary of the invention
Technical problem to be solved in the utility model is to provide the two air gap disc type electric machines of a kind of large-scale vertical, is convenient to accurately assembling and motor bulk strength high, durable in use, vibrates little when operation.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of large-scale vertical two air gap disc type electric machines, comprise axle, stator, rotor, front end housing and and rear end cap, characterized by further comprising two annular dowels, on front end housing and rear end cap, offer respectively positioning ring groove, dowel embeds in positioning ring groove and installs fixing with bolt; Stator comprises stator and lower stator, and the stator core of upper stator and lower stator is welded on respectively on the dowel of rear end cap and front end housing.
The two air gap disc type electric machines of large-scale vertical described in the utility model, is characterized in that rotor is split-type structural, and rotor comprises spoke, rotor core and retainer plate, and rotor core and retainer plate are fixed on spoke by stud.
Spoke is top in shape broad in the middle small in ends.
Spoke is sleeved on axle, and rotor core is between upper and lower stator; Spoke bottom is located by pillow block, and spoke top is located by ring key, and spoke is fixed on axle by long key.
The beneficial effects of the utility model are:
1, dowel of the present utility model embeds in positioning ring groove and installs fixing with bolt, the stator core of upper stator and lower stator is welded on respectively on the dowel of rear end cap and front end housing, this design makes the installation location of stator more accurate, be convenient to assembling in early stage and later stage maintenance, and due to the accurate positioning of stator, can ensure the reasonable gap value of stator and rotor, can not move rub the mutually phenomenon of motor damage of stator rotor after a period of time.
2, spoke is top in shape broad in the middle small in ends, more stable when rotation, difficult swing.Rotor core and retainer plate are fixed on spoke by stud, and three forms firmly entirety, operates steadily, and vibrates littlely, and noise is little.
3, spoke is sleeved on axle, and rotor core is between upper and lower stator; Spoke bottom is located by pillow block, and spoke top is located by ring key, and spoke is fixed on axle by long key, when rotated, spoke can, along the upper and lower play of axle, not affect the matched in clearance between stator rotor to rotor, motor operation is more stable, can effectively extend the useful life of complete machine.
4, the utility model is simple in structure, is suitable for practicality, and production cost is lower, suitablely in the industry cycle popularizes.
