Abstract
The utility model discloses a motor end cover provided with bottom feet. The motor end cover comprises a flange assembly connected with a motor casing and a bearing seat arranged at the middle. The motor end cover of the utility model is characterized in that the flange assembly is a double-flange structure composed of a left side flange and a right side flange, wherein the left side flange is connected with the right side flange through the bearing seat arranged at the middle and reinforcing ribs connected with the outer wall of the bearing seat so as to form on entity; the left side flange and the right side flange are provided with the bottom feet; the bottom feet are fixedly connected with the outer walls of the left side flange and the right side flange; the reinforcing ribs are evenly distributed at the periphery of the bearing seat; and the number of the reinforcing ribs is an odd number in a range of 3 to 12. The motor end cover provided with the bottom feet of the utility model is advantageous in structural simplicity and easiness in implementation, and can significantly improve the stress state of a bearing inside the motor end cover, and can form irregular airflow.
Description
Technical field
The utility model relates to a kind of End cover for motor, particularly a kind of band footing End cover for motor.
Background technology
Common motor is divided into two classes by mounting structure form difference, and a class is the motor of band footing, and a class is flanged motor.The footing of existing band footing motor is fixedly connected on the motor field frame outer wall, and End cover for motor is positioned at the footing two ends.Bearing in the end cap of motor two ends bears the load of motor as stress point, because the stress point in the End cover for motor is outside the footing support zone, just form turning torque like this between stress point in the End cover for motor and the footing, this upset moment of torsion can be applied on the motor shaft, both increase harmful bending moment to motor shaft, also increased the load of motor; On the other hand, this turning torque can also can make the End cover for motor inner bearing produce the eccentric wear phenomenon, might cause bearing running hot, causes bearing failure, has also increased vibration, noise.
The utility model content
The utility model is at the deficiencies in the prior art, provide a kind of simple in structure, can significantly improve the End cover for motor that is provided with footing of the force-bearing situation of End cover for motor inner bearing, after the utility model is applied on the motor, by improving the force-bearing situation of End cover for motor inner bearing, not only improve the force-bearing situation of motor shaft, and can avoid bearing to produce the eccentric wear phenomenon, also can reduce vibration, noise.
The utility model is achieved through the following technical solutions technical goal.
Be provided with the End cover for motor of footing, comprise the bearing pedestal with motor field frame flange connecting, centre, its improvements are: described flange is two flange arrangements that left side flange, right side flange are formed, and described left side flange and right side flange link into an integrated entity with the reinforcement that is connected the bearing pedestal outer wall by the bearing pedestal of centre; Bottom at described left side flange and right side flange is provided with footing, and described footing is fixedly connected on left side flange and right side flange outer wall.
The further technical scheme of the utility model: described reinforcement be distributed on bearing pedestal around, uniform reinforcement is 3～12.
The utility model is technical scheme further: the quantity of described reinforcement is 3～12 with interior odd number.
The utility model compared with prior art has following good effect:
1. simple in structure, be easy to realize.
2. when the utility model was on being applied to motor, the stress point in the End cover for motor was positioned within the footing support zone, can not produce turning torque, had significantly improved the force-bearing situation of End cover for motor inner bearing.
3. the quantity of reinforcement is 3～12 with interior odd number in the End cover for motor, like this, when the utility model is assembled on the motor operate as normal, can forms and irregularly distinguished and admirablely motor be cooled off good cooling effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 left view.
Fig. 3 is the A-A cutaway view among Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
As Fig. 1, Fig. 2, the End cover for motor that is provided with footing shown in Figure 3, it is the instantiation that is applied in the 15KW band footing asynchronous motor, comprise and motor field frame flange connecting 3, middle bearing pedestal 1, flange 3 is left side flange 3.1, two flange arrangements that right side flange 3.2 is formed, left side flange 3.1 and right side flange 3.2 axially link into an integrated entity with the reinforcement 2 that is connected bearing pedestal 1 outer wall by the bearing pedestal 1 of centre, reinforcement 2 be distributed on bearing pedestal 1 around, uniform reinforcement 2 is 3～12, preferable selection is: the quantity of reinforcement 2 is 3～12 with interior odd number, in the present embodiment, the quantity of reinforcement 2 is 5 and is provided with footing 4 at left side flange 3.1 and right side flange 3.2 bottoms that footing 4 is fixedly connected on left side flange 3.1 and right side flange 3.2 outer walls.
The utility model is when using, because the bearing pedestal 1 in the End cover for motor is positioned within footing 4 support zones, therefore, during shaft strength in the bearing pedestal 1, can not produce turning torque, the remarkable like this force-bearing situation that improves the End cover for motor inner bearing improves the force-bearing situation of motor shaft, and can avoid bearing to produce the eccentric wear phenomenon, also can reduce vibration, noise; The quantity of reinforcement 2 is 3～12 with interior odd number in the End cover for motor, like this, when the utility model is assembled on the motor operate as normal, can forms and irregularly distinguished and admirablely motor be cooled off good cooling effect.
