Abstract
The invention discloses a motor rotor structure with a good heat radiation property. The motor rotor structure comprises a rotating shaft and a cast-aluminum rotor, wherein a heat radiation ring is mounted on one side on the cast-aluminum rotor, of the rotating shaft; the heat radiation ring comprises a body; a mounting hole is formed in the center of the body; and a plurality of heat radiation blades extend outwards from the circumference of the body in a radiation manner. As the heat radiation ring is additionally mounted on the rotating shaft of the motor rotor structure with the good heat radiation property, the blast capacity of the rotor can be increased, heat radiation of the inner cavity of the motor can be accelerated, a blowing cooling function can be achieved for the outer ring of a bearing, and in addition, as the heat radiation ring is made of a die-casting aluminum alloy material, the temperature of the inner ring of the bearing can be effectively conducted, and a certain heat radiation function can be also achieved for the inner ring of the bearing. The motor rotor structure is simple in structure and convenient to assemble, the mold opening expense of amplified stamped sheet design can be reduced, and moreover multiple times of tests show that no adverse effect is caused for air path circulation, and a remarkable cooling effect can be achieved.
Description
Technical field
The invention belongs to motor manufacturing technology, especially relate to the motor rotor construction of a kind of perfect heat-dissipating.
Background technology
The domestic motor used on compressor of joining is owing to being subject to the restriction of compressor chassis space, and namely center height design is forced down in basic demand to expand two grades of even third gear power in same center senior middle school, and bearing temperature rise requires strict.Referring to shown in Fig. 1, Fig. 1 is traditional motor rotor construction schematic diagram, and such rotor is made up of rotating shaft and cast-aluminum rotor at present.But owing to expanding power designs, having marked Y2 mould iron core and generally need to design longer, the heat of bore of stator is not easy to distribute, cause that motor temperature rise, bearing temperature rise are too high, as adopted the design amplifying punching external diameter shortening iron core, then needing to reopen the mould of support and end cap, cost is bigger.
Summary of the invention
It is an object of the invention to provide the motor rotor construction of a kind of perfect heat-dissipating, it has the feature of simple in construction and perfect heat-dissipating, to solve the problems referred to above that in prior art, rotor exists.
For reaching this purpose, the present invention by the following technical solutions:
The motor rotor construction of a kind of perfect heat-dissipating, it includes rotating shaft and cast-aluminum rotor, wherein, described rotating shaft is provided with cooling ring in the side of described cast-aluminum rotor.
Especially, described cooling ring entirety is made up of die-cast aluminum alloy material.
Especially, described cooling ring is fixed in described rotating shaft by the mode of hot jacket.
Especially, described cooling ring includes body, and the center of described body is provided with installing hole, and the periphery of described body has outwards extended radially multiple radiator shutter.
Beneficial effects of the present invention is, compared with prior art the motor rotor construction of described perfect heat-dissipating has installed cooling ring additional in rotating shaft, the air quantity on rotor can be increased, the heat accelerating motor cavity distributes, and bearing outer ring is had blast-cold effect, another cooling ring is die-cast aluminum alloy material, can effectively transmit the temperature of bearing inner race, and bearing inner race also can play certain thermolysis.Simple in construction, it is simple to assembling；Save the die sinking expense amplifying punching design.And show do not have harmful effect and cooling-down effect obvious wind path circulation through test of many times.

Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Refer to shown in Fig. 2 and Fig. 3, in the present embodiment, the motor rotor construction of a kind of perfect heat-dissipating includes rotating shaft 1 and cast-aluminum rotor 2, described rotating shaft 1 is provided with cooling ring 3 in the side of described cast-aluminum rotor 2, described cooling ring 3 includes body 4, the center of described body 4 is provided with installing hole 5, and the periphery of described body 4 has outwards extended radially multiple radiator shutter 6, described cooling ring 3 by installing hole 5 to be fixed in the way of hot jacket in described rotating shaft 1.
When described rotating shaft 1 rotates, cooling ring 3 is driven to rotate together, when cooling ring 3 rotates, described radiator shutter 6 can blow along the wind path of motor, it is thus possible to the air quantity on increase rotor, the heat accelerating motor cavity distributes, and bearing outer ring has blast-cold effect.
Described cooling ring 3 entirety is made up of die-cast aluminum alloy material, can effectively transmit the temperature of bearing inner race, and bearing inner race also can play certain thermolysis
Above example simply elaborates ultimate principle and the characteristic of the present invention; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
