Problems solved by technology

The fan blade keyway 11 is used to fix the position of the fan blade, but the existence of the fan blade keyway 11 greatly increases the unbalance of the motor rotor, and increases the difficulty of rotor calibration and balance, which brings a lot of work to the motor rotor calibration. quantity

Embodiment Construction

[0035] see Figure 2 to Figure 6 The motor fan blade 2 includes at least two fan-shaped inserts 21, and two adjacent inserts 21 are provided with interlocking concave-convex structures on their circumferential sides, and the concave-convex structures can make at least two inserts 21 form a circle. Disc-shaped, the inner arc ends 2111 of the plurality of inserts 21 can form a shaft through hole 22 , and a blade 217 protrudes from the first end surface of each insert 21 in the axial direction of the shaft through hole 22 . When there are two inserts 21 , each insert 21 is in the shape of a semicircular sector, and the semicircular sector-shaped insert 21 may be provided with one or more blades 217 . In addition, only one blade 217 may be provided on one insert 21. According to actual requirements, the number of blades 217 corresponds to the number of matching inserts 21. For example, if there are four blades 217, the number of inserts 21 is also four. .

Abstract

The invention provides a motor fan blade, a motor, an air conditioner and a household appliance. The motor fan blade includes at least two disc-shaped inserts, and two adjacent inserts are provided with interlocking concave-convex structures on their circumferential sides. , the concavo-convex structure can make at least two inserts form a disk shape, and the inner arc ends of multiple inserts form a shaft through hole, and each insert protrudes from the first end surface of the shaft through hole in the axial direction. . The motor fan blades articulated and spliced ​​by multiple inserts have deflection, and the shaft through holes formed can be assembled with interference fit with the motor shaft, and can be firmly assembled with the motor shaft to ensure the overall strength of the motor fan blades and reduce the deformation of the motor fan blades. The motor shaft adapted to the motor fan blade does not need to have a fan blade keyway and a spring groove, which reduces the processing steps of the motor shaft and improves processing efficiency. Dynamic balancing is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor fan blade, a motor with the motor fan blade, an air conditioner with the motor and a household appliance with the motor. Background technique [0002] The motor fan blade is an important component of the motor. When the motor is running, the electric energy is converted into mechanical energy. At this time, the stator will generate a lot of heat. In order to avoid the motor from being burned due to untimely heat dissipation, it is necessary to install fan blades on the motor shaft so that during the operation of the motor, the fan blades The rotating shaft of the motor rotates to perform air cooling for the motor. [0003] see figure 1 , the existing motor shaft 1 needs to process the fan blade anti-retraction retaining ring groove 12 and the fan blade keyway 11, and at the same time install a retaining ring on the retaining ring groove 12 to fix the fan blade in the axi...
