Abstract

The invention provides a connecting mechanism of a low-noise fan and a motor and relates to a connecting mechanism of a fan and a motor. The invention aims at solving the problems that when the prior motor is directly connected with the fan, the fan is easy to deform, a motor shaft and the fan are in clearance fit to generate an eccentric center, and the fan vibrates to generate high noise when rotating at high speed. An extending shaft of a fan clamping sleeve passes through a center hole of a plane cover plate arranged on the upper part of the fan and deeply penetrates into a center hole ofan impeller gasket, the outer wall of a motor clamping sleeve comprises a cylindrical surface and a conical surface, an output shaft of the motor is arranged in an inner cavity of the motor clamping sleeve and is fixed by a locknut, the locknut is sleeved on the motor clamping sleeve and is arranged on the upper end surface of the impeller gasket, large-diameter end surfaces of the impeller gasket and the fan clamping sleeve are respectively arranged above and under the plane cover plate, and the motor is arranged in a groove of a rectification turning and fixing seat. The connecting mechanism of a low-noise fan and a motor is used for generating vacuum negative pressure which is used for adsorbing a climbing robot on a wall.

Description

technical field [0001] The invention relates to a connection mechanism between a fan and a motor. Background technique [0002] The connection structure between the fan and the motor used to generate vacuum negative pressure in the current wall-climbing robot is that the motor is directly connected to the shaft hole of the fan, and the support position is very close to the rotation center. The fan is prone to deformation and vibration noise when rotating at high speed It is very large; in addition, the gap between the motor shaft and the fan connection shaft hole is matched with the top screw to tighten it, which is easy to produce eccentricity, and then generates vibration and noise when rotating at high speed. Due to the high noise, it is difficult for the wall-climbing robot to meet the practical application requirements when it is applied to the field of anti-terrorism investigation. Contents of the invention [0003] The purpose of the present invention is to solve t...
