Problems solved by technology

But in this way, when recycling resources, it becomes difficult to separate the resin and metal; if they are crushed together, the recovered resources cannot be reused
Therefore, there is a problem of poor recyclability

Abstract

Provided is an impeller for a blower using a highly rigid resin at a flat component without using a metal flat component particularly at a bearing portion and having an improved recycling property. The impeller for the blower comprises a plurality of blades 3 around a hub 2. It has a cylindrical resin bearing portion 4 at the center of the hub for serving as a bearing for a motor shaft and a resin flat component 501 at the bearing portion for fixing the impeller for the blower to the motor shaft with a nut.

Description

Technical field [0001] The present invention relates to a blower impeller with excellent rigidity, heat resistance, and recycling properties. Background technique [0002] The structure of the existing blower impeller is generally as follows Figure 5 As shown in Figure 6, a plurality of wing-shaped blades 3 are provided around the cylindrical hub 2 to form the blower impeller 1. The motor shaft passes through the shaft sleeve part 4 located in the center of the impeller (used to be fixed to the motor), and then in the metal Nuts are screwed on the finished fixing piece 5 to fix the impeller to the motor shaft, so that the blower impeller rotates to generate blast (for details, please refer to Japanese Patent Laid-Open No. 9-228993). [0003] When it was first developed, the material of the blower impeller used metal materials such as steel plate or aluminum plate that was stamped and then coated with a variable surface. In recent years, under the trend of focusing on production ...
