Description
Technical field
The utility model is related to a kind of motor rotor constructions, more particularly, to a kind of cast-aluminum rotor.
Background technology
Existing cast-aluminum rotor includes rotor core 1 and shaft 4, and the axial end portion of rotor core 1 is equipped with aluminium end ring 2, Fig. 1
For the sectional view (due to for symmetrical structure, only drawing wherein half) of existing cast-aluminum rotor, end ring 2 is circular ring type structure,
It is shaped in 1 both sides of rotor core by die casting and stays at regular intervals, 4 end face fixed rotor iron core 1 of end ring with shaft 4.When
When high speed operation of motor, aluminium end ring 2 is acted on by centrifugal force and tangential force, is easy to happen harmful deformation and is even broken, therefore
The existing cast-aluminum rotor service life is shorter.
Utility model content
The purpose of this utility model is exactly to provide a kind of cast-aluminum rotor to overcome the problems of the above-mentioned prior art.
The purpose of this utility model can be achieved through the following technical solutions：
The axial end portion of a kind of cast-aluminum rotor, including rotor core and shaft, rotor core is equipped with aluminium end ring, which turns
Son further includes retaining ring, and the retaining ring is set in shaft, and the retaining ring is equipped with protection chamber, and the aluminium end ring is embedded in institute
The outer ring surface of the protection chamber stated, aluminium end ring is closely connect with the madial wall of protection chamber.
The aluminium end ring is cylinder ring.
The retaining ring is cylindrical retaining ring, and the first cylindrical hole and the second cylindrical hole, institute are opened up successively on the retaining ring
The first cylinder bore diameter stated is more than the second cylinder bore diameter and forms the stepped hole for running through retaining ring, and first cylindrical hole is constituted
The protection chamber, the shaft pass through and sequentially pass through the first cylindrical hole and the second cylindrical hole and closely match with the second cylindrical hole
It closes, in aluminium end ring insertion first cylindrical hole.
The shaft is interference fitted with the second cylindrical hole.
The aluminium end ring is interference fitted with first cylindrical hole.
The retaining ring is retaining ring made of nimonic steel.
Compared with prior art, the utility model has the following advantages that：
(1) the aluminium end ring of the cast-aluminum rotor of the utility model is wrapped up wherein by the protection chamber on retaining ring, and retaining ring plays guarantor
Shield acts on, and effectively prevent aluminium end ring that harmful deformation is occurred by the effect of centrifugal force and tangential force and is even broken, extends and use
Service life；
(2) the utility model retaining ring structure is simple, easily manufactured；
(3) connection of the utility model retaining ring and shaft and aluminium end ring is all made of interference fit connection type, and installation is very
It is easy；
(4) for the utility model retaining ring using retaining ring made of nimonic steel, nimonic hardness of steel is high, machinery
Performance is much better than general steel alloy, therefore is capable of the aluminium end ring of effective protection cast-aluminum rotor at high speed, and further extending makes
Use the service life.
Description of the drawings
Fig. 1 is the schematic cross-section of existing cast-aluminum rotor；
Fig. 2 is the schematic cross-section of the utility model cast-aluminum rotor.
In figure, 1 is rotor core, and 2 be aluminium end ring, and 3 be retaining ring, and 4 be shaft.
Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
As shown in Fig. 2, a kind of cast-aluminum rotor, including rotor core 1 and shaft 4, the axial end portion of rotor core 1 are equipped with aluminium
End ring 2, the cast-aluminum rotor further include retaining ring 3, and retaining ring 3 is set in shaft 4, and retaining ring 3 is equipped with protection chamber, and aluminium end ring 2 is embedded in
Chamber, the outer ring surface of aluminium end ring 2 is protected closely to be connect with the madial wall of protection chamber.
Aluminium end ring 2 is cylinder ring.Retaining ring 3 is cylindrical retaining ring 3, opens up the first cylindrical hole and the second circle on retaining ring 3 successively
Post holes, the first cylinder bore diameter are more than the second cylinder bore diameter and form the stepped hole for running through retaining ring 3, and the first cylindrical hole constitutes protection
Chamber, shaft 4, which passes through, to be sequentially passed through the first cylindrical hole and the second cylindrical hole and is fitted close with the second cylindrical hole, and aluminium end ring 2 is embedded in
In first cylindrical hole.Retaining ring 3 is the integrated ring shaped structure that full circle forges, and is not required to carry out multi-end surface cutting processing, simple in structure,
And processing relatively convenient.The utility model is by opening up stepped hole, the first cylindrical hole and the second cylindrical hole and the first cylindrical hole
The face of intersection can wrap up aluminium end ring 2 wherein, play a very good protection, effectively prevent aluminium end ring by centrifugal force and
The effect of tangential force and harmful deformation occurs and is even broken, prolong the service life.
Shaft 4 and the second cylindrical hole are interference fitted, and aluminium end ring 2 and the first cylindrical hole are interference fitted, and are connected using interference fit
Mode is connect, installation is very easy, facilitates application.
Retaining ring 3 is retaining ring 3 made of nimonic steel, and for mechanical performance far well with general steel alloy, this is also this reality
With New Energy at high speed effective protection cast-aluminum rotor an important factor for so that cast-aluminum rotor service life is long.
