Abstract
The utility model discloses a shaft and shaft bushing inner ring matching structure with vibration noise eliminating effect. A rotating shaft 3 and a rotating shaft inner ring 2 form the fastening relThe utility model discloses a combining structure of a shaft and an internal shaft lining ring for elimination of vibration noise. A rotating shaft 3 and a bearing inner ring 2 consists of fastening rationship of a rotating shaft and a bearing. The shaft journal surface combined by the rotating shaft 3 and a bearing inner ring is provided with a damping stripe 4 extending along the axial directionelation of the rotating shaft and the bearing, the surface of the shaft neck of the rotating shaft 3 is combined with the bearing inner ring and is provided with a damping texture 4 extending along ax. The utility model which has the advantages of low processing cost and noise is particularly suitable for the matched use of rotating shafts and bearings of micro motors. ial direction. The utility model has the advantages of low processing cost and low noise and is suitable for the bearing of the rotating shaft of a micro-motor in particular.
Description
The utility model belongs to machinery and makes the field.
In the ordinary course of things, rotating shaft and bearing adopt transition fit to form to be connected, but owing to the restriction of processing cost and equipment, often produce the situation of excesssive gap.Like this, in use, produce vibration during rotating shaft is rotated and cause noise.This structure is used for domestic electric appliance, and its noise produces comparatively serious negative effect to the comfort of product.
In view of the above shortcoming of prior art, the purpose of this utility model is a kind of axle of vibration noise and cooperating structure of axle bush inner ring eliminated of design, makes it to have the advantage that processing cost is low, noise is low.
The purpose of this utility model is to realize by following design.
Eliminate the axle of vibration noise and the cooperating structure of axle bush inner ring, the fastening relation of rotating shaft and bearing inner race formation rotating shaft and bearing, rotating shaft combine with bearing inner race journal surface be provided with the damping line of extension vertically.
After adopting design as above, the damping line of local interference makes rotating shaft and bearing inner race produce suitable fiting when mounted, under lower cost of production, has eliminated the vibration that the gap produces, thereby reduced running noise, especially be fit to the supporting use of micro motor shaft bearing.
Description of drawings is as follows:
Fig. 1 is the installation diagram of the utility model rotating shaft and axle bush inner ring.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is the partial enlarged drawing of rotating shaft damping line.
Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
In Fig. 1,1 is bearing, and 2 is bearing inner race, and generally speaking, the damping striped has one or more.The damping striped can adopt several different methods to process, and fairly simple method is to adopt special tooling to get rib on the surface at the axle journal position of rotating shaft, and generally speaking, rib can be several to tens of journal surface interference.
Claims (2)
1, eliminate the axle of vibration noise and the cooperating structure of axle bush inner ring, rotating shaft 3 and bearing inner race 2 constitute the fastening relation of rotating shafts and bearing, it is characterized in that, rotating shaft 3 combine with bearing inner race journal surface be provided with the damping line 4 of extension vertically.
2, according to the axle of the described elimination vibration noise of claim 1 and the cooperating structure of axle bush inner ring, it is characterized in that described damping striped has one or more.
