Description
Technical field
The utility model relates to rotor pressing ring technical field, especially a kind of rotor pressing ring of mountable internal fan.
Background technique
In the prior art, internal fan is typically mounted on the shaft of motor, therefore has to process corresponding peace on machine shaft
Step is filled, since shaft length size is big, it is therefore desirable to which dedicated large scale equipment processing had both increased the machining period of shaft, and also limited
The shaft diameter at installation fan is made；Usual internal fan is fixed in shaft by fan base, for symmetrical wind path,
Some ventilation holes are often opened on fan base, but are limited by motor inside dimension, and the ventilation hole on fan base is usually opened
Very little, be unfavorable for the cooling of motor；Internal fan is mounted in shaft, and iron core both ends are limited by fan installation dimension, therefore
In process, very high for the requirement of machining accuracy, processing capacity is also very big, causes the raising of production cost.
Utility model content
The applicant provides the structurally reasonable mountable internal fan of one kind for the disadvantage in above-mentioned existing production technology
Internal fan can be directly installed on rotor pressing ring by rotor pressing ring, reduced shaft processing capacity to realize, saved material and improve
The purpose of motor performance.
Technical solution used by the utility model is as follows:
A kind of rotor pressing ring of mountable internal fan, including the pressing ring ontology at cirque structure, the pressing ring ontology
Circumferencial direction outer ring position interval is provided with multiple ventilation holes, is spaced positioned at the pressing ring ontology one side of disposed at air vent by more
Reinforcing rib is connected with fan base, and every reinforcing rib is installed on two neighboring ventilation hole interval；It is provided on the fan base multiple
Mounting hole, and internal fan is connected by fastener.
Its further technical solution is:
The ventilation hole is at trapezoidal hole, circular hole, slotted eye or slot.
The fan base is in cirque structure, is made of steel plate.
Reinforcing rib is at rectangular parallelepiped structure.
The width of fan base and the width of reinforcing rib are equal.
The outer diameter of fan base is equal with the outer diameter of pressing ring ontology.
Internal fan is bolted in the fan base.
The beneficial effects of the utility model are as follows:
1. the utility model is simple and reasonable, easy for installation, pressing ring is connected with fan base by supporting rib, is not needed
Any space for occupying rotor ventilation opening increases the draught area of rotor, improves motor inner ventilation condition, has
Conducive to the temperature rise for reducing motor.
2. the utility model reduces the processing capacity of machine shaft, because pressing ring body length is far smaller than the length of shaft
Size, so not needing dedicated large scale equipment processing；Because not needing installation fan, shaft upper rotor part iron core two in shaft
End is no longer limited by fan installation dimension, and processing capacity is reduced, while the requirement to processing fineness reduces, to reduce production
Cost.
3. it is easy to operate when the utility model installation internal fan, internal fan need to only be covered on fan base, such as with fastener
Bolt etc. is fixed, does not need key and retaining ring；Bearing of dismantling is not needed when internal fan disassembly and replacement, it can in electrical machmary maintenance
To reduce the damage to bearing；The utility model fan base is made of steel plate, and structural support intensity is big.

Fig. 2 is the schematic perspective view (another visual angle) of the utility model.
Fig. 3 is that the utility model is mounted on the structural schematic diagram on machine shaft.
Wherein: 1, pressing ring ontology；2, ventilation hole；3, reinforcing rib；4, fan base；5, internal fan；6, shaft；7, rotor iron
Core.
Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As depicted in figs. 1 and 2, the rotor pressing ring of the mountable internal fan of the present embodiment, including the pressure at cirque structure
Ontology 1 is enclosed, the circumferencial direction outer ring position interval of pressing ring ontology 1 is provided with multiple ventilation holes 2, the pressing ring sheet at ventilation hole 2
1 one side of body is connected with fan base 4 by the reinforcing rib 3 at more intervals, and every reinforcing rib 3 is installed on two neighboring ventilation hole 2
Interval；It is provided with multiple mounting holes on fan base 4, and internal fan 5 is connected by fastener.
Ventilation hole 2 is at trapezoidal hole, circular hole, slotted eye or slot.
Fan base 4 is in cirque structure, is made of steel plate.
Reinforcing rib 3 is at rectangular parallelepiped structure.
The width of fan base 4 is equal with the width of reinforcing rib 3.
The outer diameter of fan base 4 is equal with the outer diameter of pressing ring ontology 1.
Internal fan 5 is bolted in fan base 4.
Fig. 3 is after the utility model is mounted on machine shaft 6, to install internal fan 5 by fan base 4 on pressing ring ontology 1
Structural schematic diagram, mounting structure is simple, saves space, without opening air holes on fan base 4, does not need to occupy rotor core
Any space at 7 ventilation openings improves motor inner ventilation condition, reduces the temperature rise of motor to increase rotor ventilation area.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
