Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0031] Such as figure 1 and figure 2 As shown, the composite micro-textured plane fan-shaped pad thrust bearing of the present invention includes a fan-shaped pad 1, a base ring 4 and a thrust ring 5, wherein the surface of the plane fan-shaped pad 1 is provided with a local composite micro-texture Morphology, the composite micro-texture morphology includes arc-shaped groove texture 2 and micro-pit texture 3. Such as image 3 As shown, the arc-shaped groove texture 2 and the micro-pit texture 3 are both local textures; the local texture area is located at the entrance area of ​​the plane fan-shaped pad thrust bearing. A plurality of arc-shaped grooves 2 are provided in the entrance area of ​​the plane sector pad 1 of the plane sector pad thrust bearing. The arc-shape...

Abstract

The invention provides a composite microstructure plane and sector-shaped broken tile thrust bearing. Circular-arc-shaped groove structures and micro-pit structures are formed in the surface of a plane and sector-shaped broken tile. The circular-arc-shaped groove structures are radially and uniformly distributed along the sector-shaped broken tile; and the micro-pit structures, which are uniformlydistributed in an array along the peripheral direction of the plane and sector-shaped broken tile, are arranged between the adjacent circular-arc-shaped groove structures. The circular-arc-shaped groove structures and the micro-pit structures are partial structures; and the partial structures are located in an entrance region of the plane and sector-shaped broken tile thrust bearing. According tothe composite microstructure plane and sector-shaped broken tile thrust bearing provided by the invention, a convergent gap is formed on the surface of the plane and sector-shaped broken tile of thethrust bearing and a fluid dynamic pressure lubrication effect of the thrust bearing is improved; and the effect is the same as that of a tilting broken tile thrust bearing or a Rayleigh step thrust bearing.

Description

technical field [0001] The invention relates to the field of thrust bearing surface treatment, in particular to a composite micro-textured planar fan-shaped pad thrust bearing and a processing method thereof. Background technique [0002] Thrust bearings should withstand large axial loads, so they are widely used in rotating machinery, such as pumps, steam turbines, turbochargers, internal combustion engines, ship propulsion shafting, water turbines, etc. Because the thrust bearing bears the weight of the entire shaft assembly, the inlet pressure and the axial thrust generated by the convection of the medium, it has a major impact on the safe operation and working efficiency of the unit. During the working process of the thrust bearing, because the surface of the thrust bearing cannot be lubricated quickly and effectively, the friction force increases. In this case, continuous operation will aggravate the friction and wear of the thrust bearing and greatly reduce the service...
