Abstract
The utility model discloses a water-cooling rotor. Including rotor body, set up spiral cooling water passageway in the rotor body, spiral cooling water passageway's both ends respectively with set up inhalant canal and exhalant canal on the rotor body link to each other, inhalant canal's water inlet with exhalant canal's delivery port is all set up on the same terminal surface of rotor body, this terminal surface department is provided with ceramic seal ring. The utility model discloses a design spiral cooling water passageway in the rotor, area of contact between its and the rotor is great, simultaneously, in the rotor working process, the cooling water along with the motion of spiral shape movement track, can be more effectual be used for the heat dissipation on transmitting the rotor with the low temperature of cooling water.
Description
Technical Field
The utility model belongs to the technical field of the rotor technique and specifically relates to a water-cooling rotor.
Background
The stator and the rotor are important components in the motor, heat is easily generated during working, when the heat reaches a certain threshold value, the working efficiency of the motor is easily affected, and the motor can be damaged seriously.
At present, the cooling system is usually arranged on the stator, and the part with the largest heat generation is positioned on the rotor, so when the cooling system is arranged on the stator, the cooling effect is not ideal, and the problem still exists.
SUMMERY OF THE UTILITY MODEL
The utility model provides a water-cooling rotor to not enough among the prior art.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a water-cooling rotor, includes rotor body, set up spiral cooling water channel in the rotor body, spiral cooling water channel's both ends respectively with set up inhalant canal and exhalant canal on the rotor body link to each other, inhalant canal's water inlet with exhalant canal's delivery port is all set up on the same terminal surface of rotor body, and this terminal surface department is provided with the ceramic seal ring.
In the above technical solution, preferably, the ceramic sealing ring is provided with a first through hole corresponding to the water inlet and a second through hole corresponding to the water outlet.
In the above technical solution, preferably, the ceramic sealing ring is fitted to the end face of the rotor body in a planar sealing manner.
In the above technical solution, preferably, a central axis of the water inlet passage overlaps with a central axis of the rotor body.
In the above technical solution, preferably, two ends of the rotor body are respectively connected with corresponding bearings.
The utility model has the advantages that: the spiral cooling water channel is designed in the rotor, so that the contact area between the spiral cooling water channel and the rotor is larger, and meanwhile, in the working process of the rotor, the cooling water moves along with the spiral motion track, so that the low temperature of the cooling water can be more effectively transmitted to the rotor for heat dissipation; under the same state, the permanent magnet mark can be reduced, the cost is reduced, and the power can be increased.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1, a water-cooling rotor includes a rotor body 1, two ends of the rotor body 1 are respectively connected with corresponding bearings 2, a spiral cooling water channel 3 is arranged in the rotor body 1, two ends of the spiral cooling water channel 3 are respectively connected with a water inlet channel 4 and a water outlet channel 5 which are arranged on the rotor body 1, cooling water enters from the water inlet channel 4 and is discharged from the water outlet channel 5 after flowing through the spiral cooling water channel 3.
Inlet channel 4's water inlet with outlet channel 5's delivery port is all seted up on the same terminal surface of rotor body 1, this terminal surface department is provided with ceramic seal ring 6, and ceramic seal ring has pottery to be made for the material, ceramic seal ring with the cooperation mode of rotor body terminal surface is the plane seal mode, and both have two smooth face laminatings. The ceramic seal ring is compressed between the rotor and the connecting member that mates with the rotor by the mating therebetween.
A first through hole 61 corresponding to the water inlet and a second through hole 62 corresponding to the water outlet are formed in the ceramic sealing ring 6, namely, the central axis of the first through hole is overlapped with the central axis of the water inlet, and the shape and the size of the first through hole are the same as those of the water inlet; the central shaft of the second through hole is overlapped with the central shaft of the water outlet, the shape and the size of the second through hole are the same as those of the water outlet, and cooling water sequentially passes through the first through hole and the water inlet to enter the water inlet channel and sequentially passes through the water outlet and the second through hole to be discharged outside.
Preferably, a central axis of the water inlet passage overlaps with a central axis of the rotor body.
Inside back of rotor is entered into to the cooling water, and along the motion of spiral shape orbit is made to spiral cooling water passageway along the rotation of rotor, when increase and rotor area of contact, can also get rid of the cooling water to rotor inner wall department, more effectual low temperature with the cooling water transmits to the rotor to promote the cooling effect.
Under the same state, the permanent magnet brand can reduce, and cost reduction, the power can be done bigger, under the condition that the power is the same, exists this application water cooling structure and does not exist this application water cooling structure and compare, the permanent magnet brand can reduce, and cost reduction, and after adopting this application water cooling structure, can be done bigger with the power, breaks original restriction.
Meanwhile, the water inlet and the water outlet are sealed by ceramic sealing rings, so that the water leakage in the rotating process of the rotor can be ensured.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
