Buffer device for pump shaft sleeve

Abstract

A water pump bushing buffer device includes a rotating shaft, a buffer device, a bushing, and a bushing. The rotating shaft has an outer surface. The buffer device has a buffer interface and a connection interface. The outer surface of the rotating shaft is positioned relative to the buffer interface of the buffer device but not in contact with it, and a conveying channel is formed between the outer surface and the buffer interface. The bushing has a first fixing part and a second fixing part, and the buffer interface is connected and in contact with the first fixing part. The bushing is located on the other side of the side where the bushing and the buffer device are connected, and the second fixing part of the bushing is connected and in contact with the bushing. The buffer device, bushing, and bushing are arranged sequentially from the inner center of the rotating shaft towards the outer center, so that the buffer device, bushing, and bushing are tightly fitted together as a whole. When the rotating shaft starts to rotate, it drives the buffer device, bushing, and bushing to rotate together.

Claims

1. A bushing buffer device for a water pump, comprising: a rotating shaft having an outer surface; a buffer device having a buffer interface and a connecting interface, wherein the outer surface of the rotating shaft is disposed relative to the buffer interface of the buffer device but not in contact with it, and a conveying channel is formed between the outer surface and the buffer interface; a bushing having a first fixing portion and a second fixing portion, wherein the buffer interface is connected and in contact with the first fixing portion; and a bushing located on the other side of the side where the bushing connects to the buffer device, wherein the second fixing portion is connected and in contact with the bushing. The rotating shaft is arranged in layers from the inner center of the circle outwards, consisting of the buffer device, the bushing, and the bushing. The buffer device, bushing, and bushing are tightly fitted together. When the rotating shaft starts to rotate, it drives the buffer device to rotate, which in turn drives the bushing and bushing to rotate simultaneously, thus achieving the goal of rotating the buffer device, bushing, and bushing together.

2. The shaft bushing buffer device of the water pump as described in claim 1, wherein, The water pump is a shaftless water pump.

3. The bushing buffer device for the water pump as described in claim 1, wherein, The rotating shaft is installed at the very center of the impeller body.

4. The bushing buffer device for the water pump as described in claim 1, wherein, The delivery channel is used to provide liquid transfer for the water pump.

5. The shaft bushing buffer device for the water pump as described in claim 1, wherein, The buffer device is an elastic body that can absorb the vibration energy of the rotating shaft.

6. The bushing buffer device for the water pump as described in claim 1, wherein, The buffer device is made of metal, plastic or rubber.

7. The bushing buffer device for the water pump as described in claim 1, wherein, The buffer interface of the buffer device has a corrugated shape with raised or recessed surfaces.

8. The bushing buffer device for the water pump as described in claim 1, wherein, The surface of the buffer interface that is connected and attached to the first fixing part is corrugated or smooth.

9. The bushing buffer device for the water pump as described in claim 1, wherein, The bushing and the bushing are tightly joined together by a horizontal, smooth surface structure.

10. The bushing buffer device for the water pump as described in claim 1, wherein, The coefficients of thermal expansion of the rotating shaft and the bushing are different.
