Problems solved by technology

With the emergence of high-speed heavy cutting technology, the rotation speed and load of the static pressure support increase, the shear heat of the oil film becomes larger, the oil film becomes thinner, and the deformation is uneven, which will lead to local boundary lubrication or dry friction of the static pressure friction pair, which is serious. There will be tribological failure, so improving the rotation speed of the table and the bearing capacity of the thrust bearing is a problem that must be solved at present

Embodiment Construction

[0047] It can be achieved through the following technical solutions:

[0048] Step A, input parameters

[0049] The input parameter module is composed of tabcontrol control, label control, textbox control, and radiobutton control. Select the corresponding radiobutton control, and the value behind this control is used as the input parameter.

[0050] Step B. Theoretical Calculation

[0051] Enter the relevant calculation parameters, and the "Save Data" button can save the results of this calculation to the next window for subsequent data storage, comparison and curve drawing. The theoretical calculation module is to achieve a reasonable match between the rotation speed of the worktable and the carrying capacity through calculation.

[0052] 5) Shear force acting on the oil film

[0053]

[0054] 6) Friction acting on the surface of the oil film

[0055] f f =∫∫ A τdA (2)

[0056] Since the sliding velocity υ of each point on the oil film surface is equal, so:

Abstract

The invention discloses a reasonable matching method for rotation speed and load of a double-rectangular-cavity hydrostatic thrust bearing. A rotation speed and load matching relation is obtained through theoretical derivation, the calculation process is completed by a self-compiled program, and the program comprises a parameter input module, a theoretical calculation module, a result storage module, a performance optimization module and the like. The method is developed by adopting a Visual Basic.NET mode according to the lubrication theory and the tribology principle, by applying the method, the repetitive calculation workloads of design personnel can be greatly reduced, and the calculation precision is improved and guaranteed. The method is suitable for the reasonable matching relation of the rotation speed and load of a double-rectangular-cavity hydrostatic thrust bearing and has the advantages of being visible, easy and convenient to operate and the like.

Description

technical field [0001] The invention relates to a method for reasonably matching the rotation speed and load of a static pressure thrust bearing, in particular to a method for reasonably matching the rotation speed and load of a double rectangular cavity static pressure thrust bearing. Background technique [0002] Hydrostatic thrust bearings belong to full liquid friction bearings, which have the characteristics of small friction, high oil film stiffness, high support precision, anti-vibration and long service life, so they are widely used in power machinery, military equipment, aerospace facilities and nuclear industry , is a key component of high-speed heavy-duty CNC machining equipment, and its performance directly affects the processing quality and operating efficiency of the equipment. With the emergence of high-speed heavy cutting technology, the rotation speed and load of the static pressure support increase, the shear heat of the oil film becomes larger, the oil fil...
