Abstract
The utility model discloses Novel motor rotor trim ring, described rotor pressing ring is made up of trim ring body (1) and arc teeth portion (2); Described trim ring body (1) is annular, arc teeth portion (2) is located at the outer ring of trim ring body (1), described arc teeth portion (2) is distributed in the outside of trim ring body (1), and the root of described adjacent arc teeth portion (2) seamlessly transits, and the top of described arc teeth portion (2) is provided with chamfering; Described trim ring body (1) inner ring (3) is the circle with the outer concentric of trim ring body (1), and inside is provided with bayonet socket (4).By adopting technique scheme, changing the kenel of rotor trim ring plate, increasing arc teeth portion, reaching and well coordinate motor rotor punching sheet, motor rotor punching sheet teeth portion is pushed down safely, reduce the various power that punching is subject to.
Description
Technical field
The utility model relates to motor spare and accessory parts technical field, is specifically related to Novel motor rotor ring pressing construction.
Background technology
In the motor of current use, motor occurs that motor stamping teeth portion sticks up out the generation of phenomenon of rupture in use for some time sometimes, this is owing to not pushing down rotor punching completely when rotor pressing ring is pressed on rotor punching, the centrifugal force produced in motor runs and stress own are intensively in situation, and motor rotor punching sheet teeth portion is stuck up to cut-off and split.Split once motor stamping teeth portion sticks up to cut-off, the badly damaged motor of meeting, brings economic loss to producer.
The patent No. is 201310328728.2, and name is called a kind of rotor pressing ring, and its technical scheme, for comprising rotor pressing ring body, described rotor pressing ring body is obliquely installed with the contact-making surface of rotor punching; Described rotor pressing ring body has index aperture and the cannelure for placing dynamic balance weight; Described rotor pressing ring body is gone back ring array to show ventilation hole and index aperture described in multiple ventilation hole and be positioned at cannelure.Adopt the technical scheme of above-mentioned patent, rotor pressing ring body is obliquely installed with the contact-making surface of rotor punching, installation accuracy requires high, easily causes motor stamping teeth portion to rupture, can not solve the problems of the technologies described above.
Summary of the invention
Problem to be solved in the utility model is a kind of New-type electric machine trim ring of design, reduces the generation that motor stamping teeth portion sticks up out phenomenon of rupture, makes the running of motor safety and steady more.
Technical problem to be solved in the utility model is achieved by the following technical solution:
Novel motor rotor trim ring, described rotor pressing ring is made up of trim ring body 1 and arc teeth portion 2; Described trim ring body 1 is annular, and arc teeth portion 2 is located at the outer ring of trim ring body 1, and described arc teeth portion 2 is distributed in the outside of trim ring body 1, and the root of described adjacent arc teeth portion 2 seamlessly transits, and the top of described arc teeth portion 2 is provided with chamfering; Described trim ring body 1 inner ring 3 is the circle with the outer concentric of trim ring body 1, and inside is provided with bayonet socket 4.
Be provided with installing hole 5 between the inner ring 3 of described trim ring body 1 and outer ring, fixed by installing hole 5 and motor casing.
The diameter of the inner ring 3 of described trim ring body 1 is 475mm, and the top of described bayonet socket 4 is 485mm to the air line distance of inner ring 3 opposite side; The width of described bayonet socket 4 is 25mm.
Described installing hole 5 is provided with 8, is distributed on the concentric circles between the inner ring 3 of trim ring body 1 and outer ring.
The chamfering of the root of described arc teeth portion 2 is R5.5, and the chamfering on the top of described arc teeth portion 2 is R3.
By adopting technique scheme, changing the kenel of rotor trim ring plate, increasing arc teeth portion, reaching and well coordinate motor rotor punching sheet, motor rotor punching sheet teeth portion is pushed down safely, reduce the various power that punching is subject to.The utility model adopts technique scheme, i.e. Novel motor rotor trim ring thus reduce motor rotor punching sheet teeth portion and stick up the generation of cut-offfing and splitting.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of rotor pressing ring of the prior art.
Fig. 2 is the schematic diagram of novel rotor trim ring of the present utility model.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, Novel motor rotor trim ring, described rotor pressing ring is made up of trim ring body 1 and arc teeth portion 2; Described trim ring body 1 is annular, and arc teeth portion 2 is located at the outer ring of trim ring body 1, and described arc teeth portion 2 is distributed in the outside of trim ring body 1, and the root of described adjacent arc teeth portion 2 seamlessly transits, and the top of described arc teeth portion 2 is provided with chamfering; Described trim ring body 1 inner ring 3 is the circle with the outer concentric of trim ring body 1, and inside is provided with bayonet socket 4.
Be provided with installing hole 5 between the inner ring 3 of described trim ring body 1 and outer ring, fixed by installing hole 5 and motor casing.
The diameter of the inner ring 3 of described trim ring body 1 is 475mm, and the top of described bayonet socket 4 is 485mm to the air line distance of inner ring 3 opposite side; The width of described bayonet socket 4 is 25mm.
Described installing hole 5 is provided with 8, is distributed on the concentric circles between the inner ring 3 of trim ring body 1 and outer ring.
As shown in Figure 3, the chamfering of the root of described arc teeth portion 2 is R5.5, and the chamfering on the top of described arc teeth portion 2 is R3.
Motor rotor punching sheet can well be protected when using novel rotor trim ring, thus reduction motor rotor punching sheet teeth portion sticks up the generation of cut-offfing and splitting further.
