Description

Technical Field

[0001] The invention relates to the technical field of deep groove ball bearings, and in particular to a radial liquid hydrostatic deep groove ball bearing. Background Art

[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used rolling bearings, while radial liquid conveyor is a way to transport oil to deep groove ball bearings.

[0003] Deep groove ball bearings have the following problems in actual application:

[0004] 1. When deep groove ball bearings are in use, they rely on the oil's own pressure to penetrate into the interior of the bearing for lubrication. However, the oil's own pressure delivery can easily cause reverse pressure due to the working state of the bearing, causing oil backflow. In addition, when in use, deep groove ball bearings lack the ability to detect the axial force they are subjected to when working, which leads to limitations.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a radial liquid hydrostatic deep groove ball bearing is provided to achieve a more practical purpose. Summary of the invention

[0006] The invention provides a radial liquid hydrostatic deep groove ball bearing, which solves the problem that the deep groove ball bearing lacks the ability to detect the axial force applied to the bearing during operation, thus resulting in limitations.

[0007] The present invention provides a purpose and effect of a radial liquid hydrostatic deep groove ball bearing, which specifically includes: a base and a retaining frame, the main body of the base is an annular structure, and a through hole is opened at the top end of the outer peripheral surface of the base, a connecting pipe is inserted into the inside of the through hole, a mixed flow box is installed at the top end of the connecting pipe, the mixed flow box and the connecting pipe are connected, and a pump pressure device is installed at the front end of the mixed flow box, the retaining frames are provided at two locations, and the two retaining frames are installed in the base in opposite directions, and the insides of the two retaining frames are opened with mounting holes in a ring array, the insides of the mounting holes are connected by inserting positioning pins, balls are installed on the insides of the two retaining frames, and inner rings are installed on the insides of the two retaining frames.

[0008] Furthermore, a mounting frame is fixedly connected to the outer side of the base, and there are four mounting frames in total, wherein every two laterally adjacent mounting frames form a group, and the two groups of mounting frames are respectively fixedly connected to the front and rear side positions of the base.

[0009] Furthermore, an alarm is fixedly connected to a side of the mounting frame away from the base, and a proximity switch is installed on the rear side of the longitudinal component of the mounting frame, and the proximity switch is electrically connected to the alarm.

[0010] Furthermore, the pump pressure device is used to supply air to the interior of the mixed flow box, and a supply pipe is installed on the right side of the mixed flow box, the supply pipe is connected to the mixed flow box, and a one-way valve is installed on the outside of the supply pipe.

[0011] Furthermore, a pressure plate is installed on the inner side of the mounting plate, and a limit rod is fixedly connected to the top end of the pressure plate. The limit rod is a screw rod structure, and the limit rod is limited by screwing a nut. A retaining frame is installed inside the base.

[0012] Furthermore, a slider is fixedly connected to the outer side of the guide frame, and the guide frame is slidably connected to the mounting frame through the slider, and one end of the guide frame is fixedly connected to two mounting plates in a linear array. When the oil is transported, the external air can be pressurized to the interior of the mixed flow box by starting the pump pressure device installed at the front end of the mixed flow box, and the lubricating oil entering the mixed flow box can be pressurized by the external air to more smoothly enter the interior of the base to perform automated and efficient lubrication operations on the inner ring and the ball, thereby achieving a more practical purpose.

[0013] Furthermore, when the proximity switch is in a state of being squeezed by the guide frame, the alarm is in a continuous buzzing state, a longitudinal groove is provided inside the mounting frame, and the guide frame is slidably connected inside the mounting frame.

[0014] Furthermore, a groove is provided inside the inner ring, a mounting seat is installed inside the groove through a limiting ring, an air supply pipe is installed at the front end of the mounting seat, a valve is installed on the outer circumferential surface of the air supply pipe, and airbags are installed in a ring array on the inner wall of the inner ring. The airbags and the inner ring are connected by a guide rod, and the guide rod is a telescopic structure. An anti-skid plate is fixedly connected to the side of the airbag away from the inner ring, and the side of the anti-skid plate away from the airbag is a raised structure.
