Problems solved by technology

[0002] Existing shaft motors install fan blades through the top of the external shaft, and use threaded shaft ends to install nuts, so that the rotating blades will not swim in the direction of the shaft, but with this connection method, the blades are prone to swing. It is not parallel to the end face of the motor shaft, especially when starting the motor, it will generate severe vibration and affect the service life of the product

Embodiment Construction

[0010] Such as figure 1 It is a schematic structural diagram of the present invention. A blade locking motor shaft includes a motor shaft body 1 and a motor shaft cover 2. The motor shaft body 1 passes through the motor shaft cover 2, and the center of the fan blade is provided with a shaft sleeve 3, and the shaft sleeve side The side is provided with a clamping hole 4, and both sides of the top end of the motor shaft body 1 are provided with spring clamping blocks 5, the spring clamping block 5 is placed in the clamping hole 4, and the top of the spring clamping block 5 is fixed to the blade by a fixing rod 6.

[0011] The motor shaft is fixed by the spring block 5 on the motor shaft body 1 directly passing through the fan clamping hole 4 to fix the two components, and the spring block 5 is also connected to a fixing rod 6 for fixing the blades, so that the fan blades It can keep as stable as possible during operation, and avoid vibration. The motor shaft uses a snap-type struct...

Abstract

The invention relates to a motor shaft, in particular to a vane lock type motor shaft. The motor shaft comprises a motor shaft body and a motor shaft cover. The motor shaft body penetrates through the motor shaft cover. The center of fan vanes is provided with a shaft sleeve. A clamp hole is formed in a lateral side of the shaft sleeve. Two sides of the top of the motor shaft body are respectively provided with a spring clamp block. The spring clamp blocks are placed in the clamp hole. The top end of each spring clamp block is fixed with each vane through a fixing rod. According to the motor shaft, a clamp locking structure and the fixing rods are used so that vibration degree in the process of rotation of the vanes is greatly stabilized, service life of the vanes is prolonged and operation stability is guaranteed.

Description

Technical field [0001] The invention relates to a motor shaft, in particular to a blade locking type motor shaft. Background technique [0002] The existing shaft-mounted motors all install fan blades through the top of the external shaft, and use the threaded shaft end to install the nut, so that the rotating blade will not swim in the axial direction. However, with this connection method, the blade is prone to swinging. The end face of the motor shaft is not parallel, especially when the motor is started, severe vibration will occur, which will affect the service life of the product. Summary of the invention [0003] In order to overcome the shortcomings of the existing motor shaft operation that will produce vibration, the present invention provides a blade locking type motor shaft. [0004] The technical solution adopted by the present invention to solve its technical problem is: a blade locking motor shaft, comprising a motor shaft body and a motor shaft cover, the motor shaft...
