Abstract
The invention discloses a combined carbon fiber composite material vibration-absorbing motor housing, which includes a housing, a base, a connecting ring, a bush and a short pin, the housing and the base are both made of carbon fiber composite materials, the housing is connected to the base, and the housing It is cylindrical, and both ends of the casing are provided with bushings, which are fixed by connecting rings. The connecting rings and the casing are connected by short pins, and the connecting rings and bushings are made of metal. To reduce the vibration during the operation of the motor, the traditional metal shell is replaced by the carbon fiber composite material motor shell with good damping performance. At the same time, in order to avoid the lack of heat dissipation performance of the carbon fiber composite material, the internal heat dissipation of the motor is carried out with the metal bushing to improve the smooth operation of the motor. sex.
Description
technical field [0001] The invention belongs to the field of composite material part design, in particular to a combined carbon fiber composite material vibration-absorbing motor shell and a manufacturing method thereof. Background technique [0002] The material of the traditional motor casing is cast iron or aluminum alloy, which has the function of accommodating and supporting parts such as the stator and the rotor. The casing of the invention provides a new function of vibration absorption. [0003] The motor is often used as the power source of the electromechanical system, and the vibration generated during its operation will be transmitted to other structures of the system, thereby causing vibration and noise problems of the entire system. In the whole structure of the motor, the motor casing is the part directly connected to the motor and the foundation. It not only plays the role of supporting the iron core, winding, end cover and other components, but also is the m...
