Description
Technical Field
The utility model discloses a thrust bearing oil pad that contains wedge oil pocket that can provide dynamic pressure effect belongs to heavy processing and equips the field.
Background
With the development of industry, the heavy equipment manufacturing industry faces new challenges, higher requirements are provided for the machining precision, the machining efficiency and the stability in the machining process, and the research on the heavy thrust bearing is promoted.
Under the working condition of high speed and heavy load, the base can be deformed due to insufficient bearing capacity, and the thermal deformation can be caused due to overhigh local temperature when the base is continuously operated for a long time, so that the mechanical processing can not be carried out.
Disclosure of Invention
The utility model provides a thrust bearing oil blanket that contains wedge oil pocket that can provide dynamic pressure effect makes it possess static pressure supporting and dynamic pressure supporting effect simultaneously at work, has increased its bearing capacity of work, has reduced because of bearing the deformation that too big arouses, and the oil gallery of between adjacent oil pocket is discharge lubricating oil in time in the oil pocket, avoids influencing work because of the high temperature, but this structure wide application is equipped in heavy processing manufacturing.
The technical scheme of the utility model is that: a thrust bearing oil pad with wedge-shaped oil pockets for providing dynamic pressure effects, which is an improvement on the existing oil pad in structure, comprises: wedge oil pocket, oil gallery, oil inlet, its characterized in that: the top view of the wedge-shaped oil cavity is rectangular, the main view is trapezoidal, namely the two ends of the wedge-shaped oil cavity are different in height, 12 wedge-shaped oil cavities with the same size are uniformly distributed in the circumferential direction of the oil pad, an oil return groove is formed between every two adjacent wedge-shaped oil cavities and used for discharging oil discharged from the wedge-shaped oil cavities, and the oil inlet is arranged in the middle of the lower side of the wedge-shaped oil cavity.
When the bearing is started, firstly, the hydraulic pump pumps oil into the wedge-shaped oil cavity through the oil separator, the flower disc floats under the action of the static pressure support, and the gear ring of the inner ring of the flower disc is driven by the gear set in the base to realize the rotation of the workbench. When the workbench has a certain speed, the workbench rotates to drive the lubricating oil to move towards the convergence direction of the wedge-shaped space of the oil cavity to generate a dynamic pressure effect, so that the anti-overturning moment is increased, the bearing capacity of the anti-overturning device is increased, a part of cutting force can be offset during machining, and the actual structure is prevented from deviating from a theoretical design model.
The utility model has the advantages that: the oil cavity of the oil pad is designed into a wedge-shaped structure, when the workbench reaches a certain rotating speed, a dynamic pressure effect can be generated during the bearing work, the bearing capacity of the thrust bearing is increased under the hybrid action of dynamic pressure and static pressure, the deformation of the workbench is improved to a certain extent, and the upper limit of the rotating speed of the thrust bearing is increased.

Fig. 3 is a cross-sectional view of 1/12 of the oil pad of the present invention in a mid-plane of the oil chamber.
The labels in the figure are: the oil return device comprises a wedge-shaped oil cavity (1), an oil return groove (2) and an oil inlet (3).
Detailed Description
The following describes the specific structure and embodiments of the present invention with reference to the accompanying drawings.
With reference to fig. 1, the utility model discloses a component includes wedge oil pocket (1), oil gallery (2), oil inlet (3), its characterized in that: 12 wedge-shaped oil cavities (1) with the same size are uniformly distributed in the circumferential direction of the oil pad, an oil return groove (2) is arranged between every two adjacent wedge-shaped oil cavities (1), and an oil inlet (3) is arranged in the middle of the lower side of each wedge-shaped oil cavity (1).
The utility model provides a can provide thrust bearing oil blanket that contains wedge oil pocket of dynamic pressure effect, make it possess static pressure and dynamic pressure effect simultaneously at work, its bearing capacity in work has been increased, the size of the deflection that arouses because of bearing too big has been reduced, hydraulic oil gets into wedge oil pocket (1) by oil inlet (3), exhaust lubricating oil in can in time discharging wedge oil pocket (1) in oil gallery (2) between adjacent wedge oil pocket (1), reduce the temperature rise, avoid influencing work because of the high temperature, but this structure wide application is in heavy manufacturing equipment. When the workbench rotates along the convergence direction of the wedge-shaped space of the wedge-shaped oil cavity (1), the lubricating oil is driven to move along the convergence direction of the wedge-shaped space, so that a dynamic pressure effect can be generated. When the bearing is started, the hydraulic pump pumps oil into the wedge-shaped oil cavity (1), the faceplate floats under the action of the static pressure support, and the gear of the inner ring of the faceplate is driven by the gear in the base to realize the rotation of the workbench. The bearing capacity is further increased under the hybrid action of dynamic pressure and static pressure, and the deformation of the bearing can be reduced to a certain extent.
The foregoing shows and describes the general principles and features of the present invention. The present invention is not limited to the above embodiments, and the above embodiments and the description only describe the principle of the invention, and the present invention can be further modified and improved without departing from the spirit and scope of the present invention, and the invention and the improvements are all within the scope of the claimed invention.
