Abstract
The utility model relates to a guide rail which comprises a supporting base, a slide block and a shaft. The utility model is characterized in that oil film layers or air film layers are arranged between the shaft and the slide block and the supporting base and the shaft; the end of the shaft is connected with a dynamic force drive device. When the utility model is under the ordinary state or starts, static pressure exists among the slide block, the supporting base and the shaft; when the shaft rotates with high speed, the oil film layers or the air film layers among between the shaft and the supporting base and between the shaft and the slide block generate high stable dynamic pressure during high-speed rotation; when the slide block slides on the shaft of the guide rail, the vibration of the guide rail is largely reduced, the rigidity of the guide rail is enhanced, and the precision of a machine tool is improved.
Description
One, technical field
The utility model relates to a kind of guide rail.
Two, background technology
Because the precision machine tool guide rail requires vibration little, motion is even, and so the kinematic accuracy height is the normal hydrostatic slideway that adopts.Generally at the fixedly connected bearing in axle two ends, slide block slides on lead rail axis existing hydrostatic slideway, is oil lamella between slide block and the axle, thereby reduces vibration, improves the precision of lathe.But at some special occasions, the precision of hydrostatic slideway, rigidity can't meet the demands fully.
Three, technology contents
The purpose of this utility model is at the deficiencies in the prior art, and a kind of novel guide rail that the employing dynamic and static pressure littler, that precision is higher combines of realizing vibrating is provided.
The technical solution of the utility model is as follows:
The utility model comprises bearing, slide block, axle, it is characterized in that: between axle and slide block, axle and the bearing oil lamella is arranged, axle head connects Power Drive Unit, Power Drive Unit drives the axle rotation, oil lamella between axle and bearing, slide block produces dynamic pressure effect, thereby reduces the vibration in the slide block sliding process.
Between axle of the present utility model and slide block, axle and bearing also can be the air film layer, and when axle rotated, air-flow produced stable dynamic pressure effect.
Axle of the present utility model is more than two or two, can connect a cover power-driven system simultaneously, also can connect different Power Drive Units respectively.
The utility model is when general state and starting, oil lamella or air film layer are static pressure, where necessary, Power Drive Unit drives the rotating shaft rotation, produces very high stable dynamic pressure when high speed, when sliding on the axle of slide block at guide rail, significantly reduced the lead rail axis vibration, and rigidity improves 3～10 times than static pressure, improved the precision of lathe, satisfies the requirement of high accuracy, high rigidity.
Four, drawing explanation
Fig. 1 is the utility model structural representation.
Five, the specific embodiment
As shown in Figure 1, a kind of novel guide rail comprises bearing (1), slide block (2), axle (3), it is characterized in that: between axle (3) and slide block (2), axle and the bearing (1) oil lamella (4) is arranged, axle head connects Power Drive Unit (5).
Between axle of the present utility model and slide block, axle and the bearing also can be the air film layer.
Power Drive Unit of the present utility model can be the transmission of driven by motor belt pulley, gear drive or the like.
Axle of the present utility model can be more than two or two, and they can a shared cover Power Drive Unit, also can connect different Power Drive Units respectively.
The utility model be the static pressure state between axle and slide block, bearing under general state and Power Drive Unit when just having started, when Power Drive Unit drives axle and rotates at a high speed, and oil lamella and air film interlayer generation dynamic pressure, it is littler that lead rail axis is vibrated, and rigidity is better.
Claims (5)
1, a kind of novel guide rail comprises bearing (1), slide block (2), axle (3), it is characterized in that: between axle (3) and slide block (2), axle (3) and the bearing (1) oil lamella (4) is arranged, axle head connects Power Drive Unit (5).
2, novel guide rail according to claim 1 is characterized in that: be the air film layer between axle (3) and slide block (2), axle (3) and the bearing (1).
3, novel guide rail according to claim 1 is characterized in that: axle is more than two.
4, novel guide rail according to claim 3 is characterized in that: many axles connect different Power Drive Units respectively.
5, according to the described novel guide rail of claim 3, it is characterized in that: many axles connect same set of Power Drive Unit.
