Abstract
The utility model relates to a hydrostatic thrust bearing, and concretely relates to a tilting oil pad of the hydrostatic thrust bearing. The problems of reduced work efficiency, increased energy consumption, increased material wearing, part destroy, machine damage, and even personnel casualty and great national economy loss caused by the easy appearance of failure lubrication of present hydrostatic bearings are solved in the utility model. Each of oil pad bodies is a cuboid, the upper end surface of each of the oil pad body is fixedly connected with two rectangular oil chambers in parallel along the width direction of the oil pad body, the length directions of the two rectangular oil chambers is same to the length direction of the oil pad body, an oil inlet is arranged at one end of the upper end surface of each of the rectangular oil chambers, a return oil slot is arranged between the two rectangular oil chambers, and a boss is arranged at one side of the lower end surface of the oil pad body along the width direction of the oil pad body. The hydrostatic thrust bearing is used for bearing a machine tool workbench.
Description
Technical field
The utility model 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 for 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.
The model utility content
The utility model is prone to the phenomenon of lubrication failure for solving existing hydrostatic support, 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 utility model is to solve 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, the side along its width direction on the lower end surface of lubricating pad main body is processed with boss.
The utility model compared with prior art has following beneficial effect: during work a plurality of tilting-type lubricating pad annular array of the present utility model 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, then machine table is installed on the tilting-type lubricating pad, input 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; the machine table High Rotation 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, so that the bearing capacity of hydrostatic thrust bearing improves 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 utility model is simple in structure, and the manufacturing cost is low.
