Description

Technical Field

[0001] The utility model relates to the technical field of bearing supports, in particular to a circular modular plane hydraulic bearing. Background Art

[0002] To reduce friction when transporting large mechanical equipment, hydraulic flat bearings are often used. These liquid-lubricated sliding bearings rely on externally supplied pressurized oil to create a hydrostatic load-bearing oil film within the bearing. Hydrostatic bearings operate under liquid lubrication from start to stop, resulting in zero wear, a long service life, low starting power, and the ability to operate at extremely low (even zero) speeds. These bearings also offer advantages such as high rotational accuracy, high oil film stiffness, and the ability to suppress oil film oscillation. However, they require a dedicated oil tank to supply pressurized oil, resulting in high power consumption at high speeds. In modern mechanical systems, hydraulic bearings are widely used in various heavy-load, high-precision, and high-speed applications due to their high load capacity, excellent friction characteristics, and long service life. Traditional hydraulic bearings often utilize a monolithic design, which presents numerous challenges in manufacturing, installation, and maintenance. This monolithic design is particularly inflexible when adapting to varying sizes and load requirements.

[0003] Therefore, in order to solve the above problems, a circular modular plane hydraulic bearing is designed specifically. Utility Model Content

[0006] In the above manner, the hydraulic oil pipe joint passes the hydraulic oil into the plane bearing module, and the hydraulic oil enters the oil tank, so that the oil tank and the bearing surface are filled with hydraulic oil to generate an oil film, which plays a role in reducing friction.

[0007] Furthermore, the plane bearing module includes a load-bearing part and a connecting part, both of which are cylindrical structures, the load-bearing part is located below the connecting part and the diameter of the connecting part is smaller than the diameter of the connecting part, the load-bearing part and the connecting part are an integrally formed structure, the oil tank is opened at the bottom of the load-bearing part, the pressure plate is connected to the connecting part, and the hydraulic oil pipe joint is arranged on the side of the load-bearing part.

[0008] In the above manner, the plane bearing module and the pressure plate are connected, and the two are separate structures. When the size of the parts needs to be replaced according to the use environment, the two can be disassembled and replaced to realize the modularization of the entire device.

[0009] Furthermore, an oil circuit is provided inside the plane bearing module, one end of the oil circuit is connected to the hydraulic oil pipe joint, and the other end of the oil circuit is communicated with the oil tank.

[0010] Furthermore, it also includes a fastening screw, and the connecting portion is connected to the pressure plate through the fastening screw.

[0011] In the above manner, the pressing plate and the connecting portion can be conveniently disassembled and fixed using the set screws.

[0012] Furthermore, a sealing device is included, and the sealing device is located at the bottom of the plane bearing module.

[0013] Furthermore, the sealing device includes an elastic rubber ring and a sealing ring. An annular groove is provided at the bottom of the plane bearing module. The elastic rubber ring is placed in the groove. The sealing ring is clamped in the groove and is located below the elastic rubber ring.

[0014] In the above manner, the combined use of the two sealing components can prevent the hydraulic oil from overflowing and affecting the formation of the oil film, thereby improving the stability of the entire device.

[0015] In summary, the present invention has the following advantages and beneficial technical effects:

[0016] 1. The plane bearing module and the pressure plate of the circular modular plane hydraulic bearing of the utility model are connected by fastening screws, which can be replaced according to different usage environments, realizing a modular design;
