Trend, but it is not applicable to the big well of silt content and non-transformer area.
Submersible motor is widely used in the fields such as industrial and agricultural production, mine, urban construction；Submersible motor mainly by stator,
The components such as rotor, upper end cover, lower cover, terminal box composition；Mainly and the rotor quality of critical component is fine or not as submersible motor
It is most important to motor quality；It is easy access and maintenance in practice, submersible motor mostly uses vertical type borehole mounting means,
Rotor temperature rise is gradually increased therewith when usual submersible motor operation, easily leads to meeting between conducting bar and punching slot in the process of running
There is matching loose, under self gravitation effect, conducting bar and end ring move downwardly together, will be very easy to lead to conducting bar and end
Ring is damaged, and greatly reduces the service life of product.In consideration of it, how to provide a kind of long service life, conducting bar can be prevented
The rotor of axial float is the problem that those skilled in the art need to solve.
Utility model content
The utility model is easy to happen the problem of axial float for conducting bar in the prior art, and provides a kind of service life
Rotor long, that conducting bar axial float can be prevented.
The utility model using following technical scheme in order to solve the above technical problems, realized:
A kind of rotor that can prevent conducting bar axial float, including shaft are designed, it is cylinder that shape is installed in the shaft
The rotor core of body structure, the rotor core are made of the rotor punching that several are uniformly overlapped together, and described turn
The both ends of sub- iron core are respectively equipped with a rotor end plates；The rotor core and rotor end plates are surrounded by several conducting bars
Slot, die casting has a rotor bar in the conducting bar slot described in each, and the length of the rotor bar is longer than the length of conducting bar slot
The both ends of degree and the rotor bar extend in the outside of conducting bar slot；Each one side of the rotor end plates far from rotor punching
It is equipped with a rotor pressing ring, the rotor pressing ring is fixed together with shaft, and the rotor pressing ring is far from rotor end plates
One side be uniformly installed with several limited blocks, the limited block is connected with rotor end ring far from one end of rotor pressing ring, described
Rotor end ring and one end of rotor bar be fixed together.
Preferably, limited block there are three being set on the rotor pressing ring described in each.
Preferably, the conducting bar slot is equipped with four.
Preferably, the rotor end ring and rotor bar are attached by welding manner, and welding manner is simple, can
It leans on, and welded later rotor end ring is connected firmly with rotor bar.
After adopting the above structure, beneficial effect is the utility model:
(1) the utility model structure is simple, several limit of quantity is creatively evenly arranged on rotor pressing ring end face
Block can prevent the axial direction of rotor bar and rotor end ring after rotor end ring connects integral with rotor bar by limited block
Displacement, and then can be to avoid shifting brought rotor failure problem by rotor bar, conducting bar axial float can be prevented, indirectly
The service life for improving device reduces the number of device maintenance；
(2) rotor pressing ring is fixed together with rotor in the utility model, and limited block is also fixedly connected with rotor pressing ring,
And then rotor bar, rotor end ring just will not be displaced in a circumferential direction, greatly reduced device and sent out in a circumferential direction
Damage caused by raw displacement has apparent progress meaning.
Detailed description of the invention
