Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] combine figure 1 As shown, the figure shows a top view of a vibration-damping rubber pad 1 of the present invention. At the central axis of the vibration-damping rubber pad 1 , an inner hole 10 is provided. The shape of the inner hole 10 is a circular hole. The inner hole 10 extends axially along the vibration-damping rubber pad 1 and runs through the vibration-damping rubber pad 1 . The inner hole 10 is provided to fit with the motor mounting bolts during installation. The vibration-damping rubber pad 1 also includes a plurality of slots 12, which are defined on the sidewall of the inner hole 10 in the axial direction and arranged at intervals in the circumferential direction. A conv...

Abstract

The invention provides a damping rubber gasket, which comprises an inner hole, a plurality of cutting grooves and a plurality of raised lines, wherein the axis of the inner hole is overlapped with the central axis of the damping rubber gasket; the inner hole is axially extended along the damping rubber gasket, and penetrates through the damping rubber gasket; the cutting grooves are axially reserved on the sidewall of the inner hole, and are circumferentially distributed at intervals; the raised lines are formed between the cutting grooves; and one surfaces of the raised lines face the central axis, and form the concave cambered surface of the inner hole. According to the damping rubber gasket, a contact area between the damping rubber gasket and a motor mounting bolt is enlarged; positioning accuracy is improved, and the randomness of the size of the contact area is avoided; and the flexibility of the rubber gasket with the inner hole is improved, the natural frequency of the rubber gasket is lowered, a vibration isolation frequency range is widened, a vibration transmission coefficient is lowered, and vibration isolation efficiency is improved.

Description

technical field [0001] The invention relates to the field of vibration-damping devices for air-conditioning equipment, and more specifically, to a vibration-damping rubber pad. Background technique [0002] Most of the fan motors in the existing cabinets are installed vertically, and the vibration-damping rubber pads are mostly cylindrical. The contact area between the pad and the motor mounting bolt is small. In actual operation, the rubber pad, the motor mounting bolt and the mounting hole of the rubber pad are often in a single-line contact state. The rubber pad has little attenuation of the radial vibration and tangential vibration of the motor. Because the root of the electromagnetic noise of the motor is the radial vibration and tangential vibration of the motor, the existing rubber pad design cannot fundamentally solve the problem of electromagnetic noise. [0003] In the patent document whose patent publication number is CN1920327A, a kind of "multi-pointed star" mo...
