Abstract
The utility model discloses a reduce bearing room structure of motor vibration and noise, including the motor end cover, the motor end cover in the middle of to be equipped with the annular protruding, annular arch enclose into the bearing room, annular bellied inner wall be equipped with the equally spaced annular groove of a plurality of, the annular groove in nested have a damping ring, damping ring partly be in annular arch in, it is partly that to be in the bearing indoor. The utility model provides a reduce bearing room structure of motor vibration and noise, owing to add damping ring, the effectual reduction of ability is because of the vibration of bearing operation production and the noise that consequently produces to the wholeness ability of equipment has been improved.
Description
Technical field
The utility model belongs to motor device technical field, is specifically related to a kind of bearing chamber structure reducing motor oscillating and noise.
Background technology
Noise measarement is the important topic that environmental protection faces; such as motor; noise and vibration is one of leading indicator of motor; reflect design of electrical motor quality, technological level and mounting technique level; bearing is one of necessary parts of most motor; bearing in operation process because a variety of causes unavoidably produces vibration; thus cause noise; in order to improve the competitiveness of China's motor product in international market; in the urgent need to the vibration & noise taking necessary controlling measurement or reduction to be produced by bearing operation, thus effectively reduce the vibration & noise of whole motor.
Utility model content
Not enough for prior art, the utility model provides a kind of bearing chamber structure reducing motor oscillating and noise, owing to having set up damping ring, effectively can reduce the vibration that produces because of bearing operation and the therefore noise produced, thus improve the overall performance of equipment.
For realizing utility model object, the utility model by the following technical solutions:
A kind of bearing chamber structure reducing motor oscillating and noise, comprise electric motor end cap, annular protrusion is provided with in the middle of described electric motor end cap, described annular protrusion surrounds bearing chamber, the inwall of described annular protrusion is provided with several equidistant annular grooves, described annular groove has been nested with damping ring, and a described damping ring part is in annular protrusion, and a part is in bearing chamber.
Be preferably, described damping ring cross section is circular, trapezoidal or rectangle, and circular and trapezoid cross section is installed firmly, and square-section effect of vibration and noise reduction is good.
Be preferably, described annular groove is two, and described damping ring is two, and the design of two damping rings can reduce costs, and can play good effect of vibration and noise reduction again.
Be preferably, described damping ring is that elastomeric material is made, and this materials'use life-span is long.
A kind of bearing chamber structure beneficial effect reducing motor oscillating and noise of the present utility model is: a kind of bearing chamber structure reducing motor oscillating and noise that the utility model provides, owing to having set up damping ring, effectively can reduce the vibration that produces because of bearing operation and the therefore noise produced, thus improve the overall performance of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, electric motor end cap; 2, annular protrusion; 3, bearing chamber; 4, annular groove; 5, damping ring.
Embodiment
