TH26761B - Sliding bearings for use under high loads. - Google Patents

Abstract

DC60 sliding bearing which is suitable and durable to use under high load for sliding In the rocking motion And the structure for such bearings is simple to assist in the manufacture of alloys used for the production of bearings, consisting of a sintered alloy based on a steel frame. Created that has been refined And the bearing surface is prefabricated with a beveled groove with an angle of 10 to 40 degrees relative to the direction perpendicular to the sliding direction and a width of 2 to 8 mm and the area of the groove bevel is 50. % Or less of the total inner bearing area and line in the imaginary location Perpendicular to the sliding direction cuts both the slope and the bearing area at any position. Of the inner surface Of bearings When bearings have been used; At the very least, the inclined groove will be treated with slide bearing lubricant suitable for and resistant to use under high load for sliding. In the rocking motion And the structure for such bearings is simple to assist in the manufacture of alloys used for the production of bearings, consisting of a sintered alloy based on a steel frame. Created that has been refined And the bearing surface is prefabricated with a beveled groove with an angle of 10 to 40 degrees relative to the direction perpendicular to the sliding direction and a width of 2 to 8 mm and the area of the slope of the groove is 50. % Or less of total inner bearing area and line in mental location Perpendicular to the sliding direction cuts both the slope and the bearing area at any position. Of the inner surface Of bearings When bearings have been used; At the very least, the slanting groove will be treated with lubricant.

Claims (5)

1.Sliding bearings for use under high loads Which alloys are used for making cartridges The bearings consist of a steel sintered alloy with a hammered structure. In the inner surface of Such bearings have a number of beveled grooves with an angle of 10 to 40 degrees relative to the direction perpendicular to the sliding direction and the width of such grooves range from 2 to 8 mm, and the area of The slant is 50% or less of the entire inner surface of the cassette. Such bearings An imaginary line perpendicular to the sliding direction cuts both the groove and the bearing area at a minimum of any position of the inner surface of the bearing, then the inclined groove is lubricated. 2.Sliding bearings for use under high loads in claim 1, where the greatest depth is The slant of the groove should be used in the range of 0.5 to 3 mm. 3.Sliding bearings for use under high loads in claim 1 or 2, where the bearing surfaces of such bearings are provided with a number of rows of ridges 2 to 20 μm high.
