Abstract
The invention belongs to the machining field, particularly a hydrostatic bearing with adjustable film thickness and an adjusting method, including a coat, a supporting block, a rotating shaft, wherein the support block is provided with a pressure oil duct and an oil recess, while a film gap is arranged between the rotating shaft and the supporting block, which is characterized in that, an elastomer is arranged between the supporting block and the coat, the gap between the bear shaft and the supporting block is zero when no pressure oil exists; when the pressure oil enters the oil recess, elastic deformation is generated to make the space between the rotating shaft and the supporting block form into the oil clearance and build oil film. The invention can adjust the degree of the elastic deformation of the elastomer, the size of the oil recess and the height of the dubbing pressure, so the gap after the elastic deformation is set smaller, even if the thickness of the film thickness is small, the hydrostatic bearing can reach high rigidity. The invention has reasonable structure, the oil clearance is adjusted, and the manufacture is convenient, which greatly increases the rigidity of the hydrostatic bearing.
Description
The invention belongs to field of mechanical manufacture technology, specifically is adjustable hydrostatic bearing of a kind of oil slick thickness and regulating method thereof.
Background technique
Hydrostatic bearing has long, precision advantages of higher of life-span in the mechanical field extensive application because of it, and hydrostatic bearing generally is made up of bearing housing, running shaft, but since between bearing housing and the running shaft across oil film, so its rigidity is not so good as sliding bearing.The rigidity of hydrostatic bearing depends on the size of oil slick thickness simultaneously, and oil slick thickness is big more, and rigidity is poor more; Oil slick thickness is more little, and rigidity is good more.And oil slick thickness depends on the gap between bearing housing and the running shaft, and the gap is more little, and then oil slick thickness is more little, and rigidity is also just good more.The manufacturing and the assembly technology level of each part are depended in the gap of hydrostatic bearing, but also will consider in use owing to reasons such as thermal distortions.Generally speaking, gap control is more than greater than 0.02mm.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of more reasonable structure is provided, makes the hydrostatic bearing simple, that the better oil slick thickness of rigidity is adjustable, and disclose its regulating method.
Technological scheme of the present invention is as follows: the hydrostatic bearing that a kind of oil slick thickness is adjustable, comprise overcoat, support block, running shaft, wherein support block has pressure oil duct and oil pocket, between running shaft and the support block oil clearance is arranged, it is characterized in that: an elastomer is arranged between support block and the overcoat, the elasticity physical efficiency produces resiliently deformable makes oil clearance adjustable, thereby regulates oil slick thickness.
The present invention also can support block or overcoat itself be set to elastic structure.
Regulating method of the present invention is: one have in the hydrostatic bearing of overcoat, support block, running shaft support block with outside inner room be provided with an elastomer; Gap when not having pressure oil between running shaft and support block is zero; After pressure oil enters oil pocket, utilize elastomer generation resiliently deformable to make between running shaft, the support block and form oil clearance, and set up oil film.
The present invention can regulate elastomeric elastic deformation level and oil pocket size, oil liquid pressure height, so can be provided with the oil clearance after the resiliently deformable very little, also is that oil slick thickness is very little, so just can make hydrostatic bearing reach very high rigidity.The present invention is rational in infrastructure, and oil clearance can regulate, and easily manufactured has increased the rigidity of hydrostatic bearing greatly.
