Abstract:
A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.
Abstract:
The copper-based sliding material has improved seizure resistance, even if it is free of Pb, and enables thinning of the overlay. The copper alloy provided consists of from 0.1 to 2% of Ag, from 1 to 10% of Sn, and the balance consisting of Cu and unavoidable impurities and, further said Ag and Sn do not essentially form the secondary phases but are in complete or essentially solid-solution state in the Cu matrix.
Abstract:
A helical groove 1B is formed in the sliding surface 1A of a sliding bearing 1 over the entire axial region thereof. To establish the height of a peak 1a defined by the helical groove 1B, an imaginary reference line L extending parallel to the axis is formed which is determined such that the total cross-sectional area of all the peaks 1a is equal to the total cross-sectional area of all the valleys 1b when the helical groove 1B is considered in axial section. A height, as measured from the reference line L to the top 1a' of the peak 1a is chosen in the range of from 1 to 8 .mu.m. The space created by forming the valleys 1b allows the supply of lubricant oil to be increased, thereby simultaneously achieving a reduction in the frictional resistance and the occurrence of an impact sound.
Abstract:
Sliding bearing 1 comprises a bearing alloy layer 2 having peaks of a height h, an intermediate layer 3 of a thickness y, and an overlay layer 4 having a thickness t at the top of the peak. The parameters h, y and t are chosen in a range which satisfies the inequalities: 1.ltoreq.h.ltoreq.8 (1), 0
Abstract:
[Task] The solid-lubricant layer applied on the surface of Al or Cu-based bearing alloy is improved so as to satisfactorily demonstrate the properties of the solid lubricant. [Means for Solution] The solid lubricant dispersed in the solid-lubricant solid-lubricant layer exhibits 85% or more of the relative C axis intensity ratio defined below. The relative C axis intensity ratio=the accumulative intensity of (002), (004) and (008) planes relative to the accumulative intensity of (002), (004), (100), (101), (102), (103), (105), (110) and (008) planes detected by X ray diffraction.

A sliding bearing for an internal combustion engine; the sliding bearing having a groove formed substantially circumferentially on an inner circumferential face of the sliding bearing; the width of the groove being smaller than 0.6 mm, and the ratio of the width of the groove to depth of the groove being larger than 40.
Abstract:
To enhance the seizure resistance of sliding bearing material which has a layer (4) of aluminum-oxide (1) on the surface of the lining (5) consisting of aluminum-alloy bearing, the layer (4) consists of mixed phase of aluminum oxide (1) and tin oxide (2).
Abstract:
Aluminum bearing alloy uses Bi having a higher melting point than Sn as a low melting point metal, and also utilizes a selected element(s) which are simultaneously added as well as the amount of such addition. In this manner, aluminum bearing alloy exhibiting fatigue strength and seizure resistance which are excellent than those of conventional Bi-containing aluminium bearing alloy is provided.

Abstract:
In a plane bearing comprising a lining having first concavities on the surface thereof, and an overlay formed on the bonding layer, the seizure resistance of the bearing with worn overlay is enhanced by determining the first length of first concavities as seen in a direction perpendicular to a sliding direction non-equal to the second length of said first concavities as seen in the sliding direction.
