Background technique
Threephase asynchronous machine is at low cost with its, high reliability, is widely used in various industries.When designing motor, to mitigate
The weight of motor entirety, often increases rotor field spider between rotor core and motor shaft.In existing rotor field spider and rotor core
In fixed solution, rotor field spider and rotor core prevent rotor core circumference side by flat key between the two using being interference fitted
To play.There is very big risk in scheme as shown in Figure 1 and this: when rotor core and rotor field spider interference fit fail, meeting
Rotor core axial float is caused, motor damage is caused.
It is CN201320865387.8 through patent searching number, discloses a kind of rotor field spider and a kind of Rotor Assembly,
Rotor field spider is used to support a rotating body in Rotor Assembly, and rotor field spider has positioning step along axial one end,
There is flange along the axial other end, positioning step and the flange extend radially outward respectively, for being fastened on the rotation
It turns along axial both ends.Rotor Assembly includes rotary body and the rotor field spider, and rotor field spider is supported on the rotation
In vivo, the positioning step of rotor field spider and the flange are fastened on rotary body along axial both ends respectively.The rotor branch of the structure
Frame has the advantages that the processing is simple and balanced weight, Rotor Assembly simple, at low cost and unbalance dynamic with assembly technology
Measure low advantage.However the rotor field spider is unable to satisfy the problem of series of products rotor field spider needs multiple mold.
Utility model content
The utility model is directed to the deficiency of existing product, and provides a kind of axis of threephase asynchronous motor rotor rack
To fixed structure.The technical problem to be solved by the utility model is in view of rotor field spider in the above threephase asynchronous machine and turning
Sub- iron core is axial without fixed problem, and the utility model passes through height adjustment ring and rotor core interference fit, axial restraint ring
It is fixed with rotor core, realizes the dual axial restraint of rotor field spider and rotor core, improve rotor field spider and rotor core
Reliability, while ring height is adjusted by replacement and can adapt to the requirement of product seriation, avoid series of products rotor field spider from needing
The problem of wanting multiple mold.
A kind of axial fixing structure of threephase asynchronous motor rotor rack of the utility model, rotor field spider installation
On the motor shaft of motor, interior step is provided on the motor shaft, rotor field spider is mounted on the interior step of motor shaft, rotor
Bracket two sides are set with height adjustment ring, and the outer sheath of height adjustment ring is equipped with axial restraint ring, axial restraint ring and rotor
Iron core is fixed.
Further, the axial restraint ring is realized by positioning pin and is fixed with rotor core circumferencial direction, axial restraint ring
It is fixed by rivet and rotor core.
Further, the height adjustment ring and rotor core are interference fit, and magnitude of interference is greater than rotor field spider and rotor iron
The magnitude of interference of core.
Further, the axial restraint ring, the length of rotor field spider are constant, and the length of height adjustment ring can be according to rotor
The length of the inner hole of iron core carries out the design adjustment of different length.
Compared with existing rotor field spider and rotor core fixed form, the beneficial effects of the utility model are: structure is closed
Reason, it is easily fabricated, it is practical, securely and reliably, by height adjustment ring and rotor core interference fit, axial restraint ring and turn
Sub- iron core is fixed, and realizes the dual axial restraint of rotor field spider and rotor core, improves the reliable of rotor field spider and rotor core
Property, while ring is adjusted by replacement different height and can adapt to the requirement of product line words, avoid series of products rotor field spider from needing
The problem of wanting multiple mold.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
In figure: rotor core 1, rotor field spider 2, motor shaft 3, height adjustment ring 4, positioning pin 5, axial restraint ring 6, rivet

Specific embodiment
Below with reference to embodiment, the utility model will be further described.
A kind of axial fixing structure of threephase asynchronous motor rotor rack of the utility model is mainly by rotor iron
Core 1, rotor field spider 2, motor shaft 3, height adjustment ring 4, positioning pin 5, axial restraint ring 6, rivet 7 form.
A kind of axial fixing structure of threephase asynchronous motor rotor rack, rotor field spider 2 are mounted on the electricity of motor
On arbor 3, characterized in that interior step is provided on the motor shaft 3, rotor field spider 2 is mounted on the interior step of motor shaft 3,
2 two sides of rotor field spider are set with height adjustment ring 4, and the outer sheath of height adjustment ring 4 is equipped with axial restraint ring 6, the axial direction
Fixed ring 6 realizes by positioning pin 5 and fixes with 1 circumferencial direction of rotor core that axial restraint ring 6 passes through rivet 7 and rotor core 1
Fixed, the dual axial restraint of rotor field spider and rotor core improves the reliability of rotor field spider and rotor core.
The height adjustment ring 4 is interference fit with rotor core 1, and magnitude of interference is greater than rotor field spider 2 and rotor core 1
Magnitude of interference will cause rotor core axial float, lead when effectively avoiding rotor core and rotor field spider interference fit failure
The problem of causing motor damage.
