Abstract
The utility model discloses a vibration absorbing structure in an electric motor, which comprises an end cover (4) and a bearing support (1) arranged in the end cover (4), and is characterized in that a bearing (3) is arranged on the bearing support (1), and a vibration absorbing layer (2) is arranged between the bearing (3) and the bearing support (1). In the vibration absorbing structure, a damping rubber layer is arranged between the bearing and the bearing support, the vibration of the bearing is eliminated, and the impact between the bearing and the bearing support can be slowed down effectively, so that the noise can be reduced when the electric motor operates, and the performance of the electric motor can be ensured; in addition, the service life of the bearing can also be prolonged. The vibration absorbing structure can eliminate vibration, can reduce the noise when the electric motor operates, and can ensure the performance of the electric motor. The vibration absorbing structure is also characterized in that the implementation structure is simple, and the vibration absorbing structure is convenient to use. The vibration absorbing structure can be suitable for a high-speed three-phase motor.
Description
Technical field
The utility model relates to a kind of weakening structure, bearing pedestal on particularly a kind of end cap and the weakening structure between the bearing.
Background technology
One bearing pedestal often is set on the electric motor end cap is used to install bearing, the bearing inner sleeve dress is equipped with the rotating shaft of rotor.Directly link to each other between existing bearing seat and bearing, in the process of the rotor rotation of high-speed electric expreess locomotive, velocity of rotation is very fast, and bear vibration is bigger, makes that collision is comparatively fierce between bearing pedestal and the bearing, and the noise that motor produces is bigger, influences motor performance.
The utility model content
The purpose of this utility model is, the weakening structure in a kind of motor is provided.The utility model can be eliminated vibration, and the noise when reducing machine operation guarantees motor performance.
The technical solution of the utility model: the weakening structure in a kind of motor comprises end cap and is arranged on the interior bearing pedestal of end cap that it is characterized in that: described bearing pedestal is provided with bearing, is provided with one deck weakening layer between bearing and the bearing pedestal.
In the weakening structure in the aforesaid motor, described weakening layer is the damping rubber layer.
Compared with prior art, the utility model is eliminated bearing vibration by a damping rubber layer is set between bearing and bearing pedestal, effectively slow down the collision between bearing and the bearing pedestal, thereby the noise when reducing machine operation guarantees motor properties; Can also prolong the useful life of bearing in addition.The utility model can be eliminated vibration, and the noise when reducing machine operation guarantees motor performance.The utility model also has the characteristics simple in structure and easy to use of implementing.The utility model is applicable to the high speed three phase electric machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-bearing pedestal, 2-weakening layer, 3-bearing, 4-end cap.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.Weakening structure in a kind of motor constitutes as shown in Figure 1, comprises end cap 4 and the bearing pedestal 1 that is arranged in the end cap 4, and it is characterized in that: described bearing pedestal 1 is provided with bearing 3, is provided with one deck weakening layer 2 between bearing 3 and the bearing pedestal 1.
Reasonable is that described weakening layer 2 is damping rubber layers.
The utility model can be eliminated bearing vibration by the damping rubber layer, thereby the noise when reducing machine operation makes motor stable, guarantees motor properties.
Claims (2)
1. the weakening structure that motor is interior comprises end cap (4) and is arranged on the interior bearing pedestal (1) of end cap (4), and it is characterized in that: described bearing pedestal (1) is provided with bearing (3), is provided with one deck weakening layer (2) between bearing (3) and the bearing pedestal (1).
2. the weakening structure in the motor according to claim 1, it is characterized in that: described weakening layer (2) is the damping rubber layer.
