Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-3, a heat dissipation type motor rotor, including rotor body 1 and rotor shaft 2, wherein, rotor body 1 and rotor shaft 2 are prior art, and rotor body 1 and rotor shaft 2 fixed connection, can drive rotor shaft 2 and rotate when making rotor body 1 rotate, rotor shaft 2 surface is fixed with gear one 3, can drive gear one 3 and rotate when making rotor shaft 2 rotate for the motor housing, the one end that rotor body 1 was kept away from to gear one 3 still rotates and installs support frame 4, support frame 4 is fixed in motor housing inner wall, support frame 4 can not rotate when making rotor shaft 2 rotate, the one end that rotor body 1 was kept away from to gear one 3 still is fixed with impeller one 5, impeller one 5 is prior art, make gear one 3 can drive impeller one 5 and rotate when rotating, then impeller one 5 blows outside air to rotor body 1, cool down rotor body 1, the one end that rotor body 1 is close to rotor body 1 still is provided with subassembly 6, the one end that rotor body 1 was kept away from to support frame 4 still is fixed with (not shown in the figure), prevent that motor body from getting into the inside during operation, thereby the filter screen that rotor 1 can be damaged during the life-span of dust is caused to the rotor, the life-span of the rotor can be damaged.

As shown in fig. 4, the exhaust assembly 6 includes an inner gear ring 11 rotationally connected with the support frame 4, the inner gear ring 11 is connected with the gear one 3 through a gear two 12, wherein the gear two 12 is rotationally installed at one end of the support frame 4 close to the rotor body 1, and the gear two 12 is engaged with the inner gear ring 11 and the gear one 3, so that the inner gear ring 11 can be driven to rotate when the gear one 3 rotates, one end of the inner gear ring 11 close to the rotor body 1 is further fixed with an impeller two 13, the impeller two 13 can blow out air in the motor, meanwhile, due to the design that the impeller one 5 blows outside air to the rotor body 1, the impeller two 13 can exhaust air pumped in by the impeller one 5, one end of the support frame 4 close to the rotor body 1 is further provided with a retainer ring 7, wherein the retainer ring 7 is used for separating the impeller one 5 from the impeller two 13, so that air blown to the rotor body 1 just by the impeller one 5 can be prevented from being sucked by the impeller two 13, and better heat dissipation can not be carried out on the rotor body 1, and the using effect of the device is affected.
