[0002] The bell housing is mainly used to connect the high-pressure pump and the motor, and plays a supporting and fixing role. However, since the high-pressure plunger pump rotates at a high speed and has a large pulse during operation, it will resonate with the connecting parts, resulting in extremely high noise, which will cause harm to the personal safety of on-site operators.

[0003] Among them, the existing patent CN202121484399.7 is a shock-absorbing structure for a bell-shaped cover. When the bell-shaped cover is installed, the upper clamping ring and the lower clamping ring are slid to the middle of the hollow pipe fitting, and then the upper clamping ring and the lower clamping ring are fixed to the hollow pipe fitting through the locking bolt and the locking nut, so that the bell-shaped cover body is fixed. After the bell-shaped cover body is fixed, a first threaded hole is provided on the column and the first flange, and a second threaded hole is provided on the upper end face of the second flange, so that the installer can conveniently install the bell-shaped cover body between the high-pressure pump and the motor. Reinforcing ribs and reinforcing rings are fixedly connected through the inner cavity of the first flange. There are 8 reinforcing ribs in a circular array around the central axis of the first flange, which can provide a better support effect for the first flange, making it less likely to be damaged during use, thereby improving the service life of the bell-shaped cover to a certain extent.

[0004] However, when this type of bell cover is connected to the motor, due to the large number of motor types, when the motor base is square, although the bell cover and the motor flange can be connected, they cannot be quickly positioned and installed, and a gap will be generated when the bell cover and the motor are connected, and external dust will enter the inside of the bell cover through the gap; therefore, it does not meet the existing needs, and we have proposed a bell cover for a motor.
