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
The present invention relates to a kind of lubricating pad of hydrostatic thrust bearing.
Background technique
Along with heavy duty appearance at a high speed, country begins to strengthen the research to the active and static pressure combination, yet mainly is the research at radial bearing, and the developmental research of thrust-bearing also seldom.In actual applications, the effect of hydrostatic support is also more and more obvious, but the appearance along with the high-speed overload technology, the phenomenon of lubrication failure often appears in existing hydrostatic support, lubrication failure not only can make working efficiency reduction, energy consumption increasing, fret wear increase, and can produce part destruction, causes machine breakdown, even bring casualties, bring economic loss to country.
Summary of the invention
The present invention is for solving the phenomenon that existing hydrostatic support is prone to lubrication failure, and cause working efficiency reduction, increasing energy consumption, increase fret wear, and can produce part destruction, cause machine breakdown even bring casualties, bring the problem of heavy economic losses to country, and then a kind of tilting-type lubricating pad of hydrostatic thrust bearing is provided.
The present invention solves the problems of the technologies described above the technological scheme of taking to be:
A kind of tilting-type lubricating pad of hydrostatic thrust bearing comprises the lubricating pad main body, the lubricating pad main body is cuboid, the upper-end surface of lubricating pad main body is connected with two rectangle oil pockets side by side along its width direction, and the length direction of two rectangle oil pockets is identical with the length direction of lubricating pad main body, one end of each rectangle oil pocket upper-end surface is processed with oil inlet hole, be processed with oil-return groove between two rectangle oil pockets, a side of its width direction of upper edge, lower end surface of lubricating pad main body is processed with boss.
The present invention compared with prior art has following beneficial effect: during work a plurality of tilting-type lubricating pad annular array of the present invention are installed on the hydrostatic thrust bearing, and boss one end of tilting-type lubricating pad is placed down, hydrostatic thrust bearing is installed on the lathe base, the width direction of tilting-type lubricating pad arranges towards the axle center of lathe base, machine table is installed on the tilting-type lubricating pad then, import lubricant oil by oil pump to oil inlet hole, make to form one deck oil film between supporting element and supported, make between machine table and the tilting-type lubricating pad to be in the fully liquid lubricating status; When starting the lathe workbench main shaft; machine table rotates at a high speed; machine table just and between the tilting-type lubricating pad has relative movement like this; because the lower end of lubricating pad main body is processed with boss; under the effect of lubricating oil pressure; each tilting-type lubricating pad just can tilt to the inside; thereby make between machine table and a plurality of tilting-type lubricating pad and produce wedge gap; so just, satisfied the condition that forms dynamic pressure; produce dynamic pressure by hydrostatic bearing, reach the effect of active and static pressure combination, make the bearing capacity of hydrostatic thrust bearing improve 30%; efficiently solve the problem of lubrication failure; improved working efficiency; reduced energy consumption; reduce fret wear, protected machine parts, guaranteed staff's personal safety; and the present invention is simple in structure, and the manufacturing cost is low.
