specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1 to Figure 5 Explain that a tiltable oil pad of a hydrostatic thrust bearing in this embodiment includes an oil pad main body 1, which is a cuboid, and two rectangular oil pads are fixed side by side on the upper end surface of the oil pad main body 1 along its width direction. chamber 1-1, and the length direction of the two rectangular oil chambers 1-1 is the same as the length direction of the oil pad main body 1, and one end of the upper end surface of each rectangular oil chamber 1-1 is processed with an oil inlet hole 1-1-1, An oil return groove 1-2 is processed between the two rectangular oil chambers 1-1, and a boss 1-3 is processed on the lower end surface of the oil pad main body 1 along its width direction.

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 Note that the oil inlet holes 1 - 1 - 1 on the two rectangular oil chambers 1 - 1 of this embodiment are respectively provided at both ends of the oil pad main body 1 . Such a design enables the lubricating oil to flow evenly and improves the bearing capacity of the hydrostatic thrust bearing. Other components and connections are the same as those in the first embodiment.

[0010] Working principle: when working, a plurality of tilting oil pads of the present invention are installed in a circular arrangement on the static pressure thrust bearing 2, and the boss end of the tilting oil pad is placed downwards, and the static pressure thrust bearing is installed on the machine tool base , the width direction of the tilting oil pad is set towards the axis of the machine base, and then the machine tool table 3 is installed on the tilting oil pad, and lubricating oil is input to the oil inlet hole 1-1-1 through the oil p...

Abstract

The invention discloses a tilting-type oil pad of a hydrostatic thrust bearing. The tilting-type oil pad relates to a hydrostatic thrust bearing and aims at solving the problems that as the existing bearings are easy for lubrication failure, the problems of reducing the work efficiency, increasing the energy consumption and enhancing the material wear are caused. In addition, part damages which can cause machine breakdown and even casualties are generated and heavy economic losses are generated to the country. An oil pad body is shaped like a cuboid; two rectangular oil chambers are fixedly connected in parallel on the upper end face of the oil pad body along the width direction; in addition, the length directions of the two rectangular oil chambers are same with the length direction of the oil pad body; an oil inlet hole is drilled in one end of the upper end face of each rectangular oil chamber; a return chute is formed between the two rectangular oil chambers; and a boss is formed at one side along the width direction on the lower end face of the oil pad body. The oil pad is applicable to bearing machine tables.

Description

technical field [0001] The invention relates to an oil pad of a static pressure thrust bearing. Background technique [0002] With the emergence of heavy-duty high-speed, the country has begun to increase the research on the combination of dynamic and static pressure, but it is mainly for the research of radial bearings, and the development and research of thrust bearings is still very little. In practical applications, the role of static pressure bearings is becoming more and more obvious. However, with the emergence of high-speed and heavy-duty technology, the existing static pressure bearings often suffer from lubrication failures. Lubrication failures will not only reduce work efficiency and reduce energy consumption Increase, material wear increases, and it will cause damage to parts, cause machine damage, and even cause casualties, bringing economic losses to the country. Contents of the invention [0003] The present invention solves the phenomenon that the existin...
