Abstract
The utility model relates to a hydrostatic bearing, and discloses a hydrostatic bearing applied to a grinding head of a grinding machine. The hydrostatic bearing applied to the grinding head of the grinding machine comprises a grinding wheel (1), conical-tile oil cavities (2), a main shaft (3), an unloading mechanism (4) and a belt pulley (5). The main shaft (3) is provided with the two conical-tile oil cavities (2) symmetrically. The grinding wheel (1) is arranged at one shaft end of the main shaft (3), and the unloading mechanism (4) is arranged at the other shaft end of the main shaft (3). The unloading mechanism (4) is connected with the belt pulley (5) through a shaft. The hydrostatic bearing applied to the grinding head of the grinding machine is simple in structure, end surface oil cavities are avoided, the assembling clearance of the shaft and a bearing pad is convenient to adjust, the ideal fit clearance can be achieved by thickening or thinning an adjusting shim, and the throttling ratio of the hydrostatic bearing can be guaranteed easily.
Description
Technical field
The utility model relates to a kind of bearing, be specifically related to a kind of hydrostatic bearing that is applied on the grinder head.
Background technology
The present column type bearing shell bearing that all adopts of domestic a lot of bistrique hydrostatic bearings, for control main shaft axially and radial displacement, respectively by grease chamber radially and axially the grease chamber produce the balance that radial thrust and axial thrust realize main shaft.The bearing bush structure of this structure is fairly simple, but on the one hand because the fit-up gap of axle and bearing shell will lean on the accuracy of manufacture of axle and bearing shell to guarantee, if the manufacturing dimension of axle or bearing shell is overproof, bigger than normal just being difficult in installation time crack adjusted, and guarantees that suitable gap guarantees suitable throttling ratio thereby only have by again making axle or bearing shell; On the other hand the easing gear of this bistrique all in its back-end, main shaft is longer, causes the Rigidity and strength of bistrique to reduce.Use has brought very large inconvenience to grinding machine.
The utility model content
For the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of hydrostatic bearing that is applied on the grinder head, simple in structure, there is not the end face grease chamber, the fit-up gap of adjusting axle and bearing shell is quite convenient, only need just can obtain desirable fit clearance with adjusting the pad thickening or reducing, be easy to guarantee its throttling ratio.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of hydrostatic bearing that is applied on the grinder head, comprise emery wheel, cone watt oil pocket, main shaft, unloading mechanism and belt wheel, be symmetrically arranged with two cone watt oil pockets on the main shaft, emery wheel is arranged on an axle head of main shaft, another axle head of main shaft is provided with unloading mechanism, and unloading mechanism links to each other with belt wheel by axle.
According to above-mentioned a kind of hydrostatic bearing that is applied on the grinder head, wherein, the cone of described two cone watt oil pockets watt has axiality.
According to above-mentioned a kind of hydrostatic bearing that is applied on the grinder head, wherein, drive a plurality of oil-recovery tanks on the external peripheral surface of the bearing shell of described two cone watt oil pockets.
The utility model is simple in structure, does not have the end face grease chamber, and the fit-up gap of adjusting axle and bearing shell is quite convenient, only needs just can obtain desirable fit clearance with adjusting the pad thickening or reducing, and is easy to guarantee its throttling ratio.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: a kind of hydrostatic bearing that is applied on the grinder head, it comprises emery wheel 1, cone watt oil pocket 2, main shaft 3, unloading mechanism 4 and belt wheel 5, be symmetrically arranged with two cone watt oil pockets 2 on the main shaft 3, emery wheel 1 is arranged on an axle head of main shaft 3, another axle head of main shaft 3 is provided with unloading mechanism 4, and unloading mechanism 4 links to each other with belt wheel 5 by axle.
Cone that it should be noted that described two cone watt oil pockets 2 watt has axiality.
In addition, drive a plurality of oil-recovery tanks on the external peripheral surface of the bearing shell of described two cone watt oil pockets 2, to guarantee its throttling action.
This specific embodiment can be inner at bistrique with the easing gear design when design, greatly shortens the length of main shaft, thereby also improved the Rigidity and strength of bistrique.
This specific embodiment is simple in structure, does not have the end face grease chamber, and the fit-up gap of adjusting axle and bearing shell is quite convenient, only needs just can obtain desirable fit clearance with adjusting the pad thickening or reducing, and is easy to guarantee its throttling ratio.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
