The surface of the overlay (3) comprises round raised portions (4) and depressed portions (6), wherein, in relation to the horizontal section plane (7), the raised portions (4) cover a proportion of the surface area amounting to 30% to 50%, based on the entire surface area of the plain bearing, the section plane (7) being at a height at which the total proportion of the surface area consisting of the raised portions (4), and obtained in vertical section, is equal to the total corresponding proportion consisting of the depressed portions (6). The round raised portions exhibit a diameter D of 3 to 8 .mu.m, in plan view, wherein, in the case of raised portions (4) and depressed portions (6) which in plan view are not circular, this value relates to the maximum diameter.

Abstract: A sliding bearing for supporting shafts and the like, with a bearing body made of plastic and a housing supporting the bearing body, where the sliding bearing essentially encloses the full circumference of the shaft. The bearing body (1) displays a slit (2) extending along the entire length of its axis and at least one deformable zone, likewise extending along the entire length of the axis, which allows the slit (2) to be opened so that the bearing body (1) can essentially be fitted to the shaft, and also removed from the shaft, in the radial direction. This drastically reduces the work involved in replacing the bearing body during repairs. The bearing body (1) can comprise individual webs (3) which are connected to one another via deformable zones designed as flexible film bridges (6) which can be locked in place in the housing by means of projections (7) provided on the webs (3).

Abstract: A sliding bearing comprises a back metal and a bearing alloy layer formed thereon, the thickness of the back metal gradually decreasing from the middle portion toward each axial end portion, and the thickness of the bearing alloy layer being increased at each axial end portion. The bearing alloy layer has a Young's modulus smaller than that of the back metal of steel plate and hence it is elastically deformed with greater ease, and therefore, particularly at the beginning of the use, the oil film pressure at each axial end portion becomes higher when misalignment takes place, with the result that the bearing alloy layer is elastically deformed in the direction of compression. In consequence, the oil film thickness at opposite end portions is increased to prevent rupture of oil film, thus avoiding occurrence of metal contact.

Abstract: A plastic gear is rotatably supported on at least one plastic fixed support stud, which is preferably formed of plastic and molded on a metal support plate. The fixed support stud has three equiangularly spaced lobes extending from its outer surface without any nominal clearance with an inner surface of a hub of a plastic gear defining a bore in the gear hub to receive the fixed support stud. The lobes cause deformation of portions of the gear hub between the adjacent lobes. By increasing the clearance between the outer surface of the fixed support stud and the inner surface of the gear hub, spaces are provided between the adjacent lobes to allow portions of the inner surface of the gear hub to extend thereinto due to the deformation of the plastic. This reduces the vibration or jitter of the plastic gear, which is the output gear of a gear train for driving a photoconductive drum of a laser printer to improve its print quality.

The ratio of the installation free spread S to the external bearing diameter D is defined by: 0.025.ltoreq.S/D .ltoreq.0.05.
