Abstract

The invention specifically discloses a novel wind blade assembly, which includes: a shaft body, the top of the shaft body is provided with a keyway for installation; a wind pan, the middle part of the wind pan is provided with a splicing through hole that is clamped and matched with the shaft body; The side end of the wind disk is provided with a mounting hole, and the mounting hole is facing the splicing through hole; the fan blade, the fan blade can pass through the mounting hole in turn, the installation keyway and the wind disk and the shaft body can be connected to each other. Disassemble the connection as a whole. The fan blade assembly of the present invention is flexible and convenient to operate, which can reduce excessive use of tools, thereby avoiding the use of tools to cause the blade to break and fail; at the same time, its stability is further improved, and it can also avoid the difficulty of processing and disassembling the fan blade assembly when it is subsequently assembled with the motor increase.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a fan blade assembly and a motor having the same. Background technique [0002] When the motor is running under operating conditions, the conversion of electrical energy into mechanical energy is realized, and in the process of motor energy conversion, a part of the energy is lost and converted into the form of thermal energy. In order to avoid motor burnout due to untimely heat dissipation, it is necessary to install fan blades on the non-shaft extension end of the motor. The function of the fan blades is to force air convection. When the motor is running, the fan blades rotate with the motor shaft to cool the motor for heat dissipation. , the cooling method of installing the fan blades on the non-shaft extension end of the motor is called the self-fan cooling method of the motor. [0003] However, in the traditional way of fixing the fan blade and the shaft, the fan blade key i...
