Patent
Taiho Kogyo Co. and Toyota Jidosha Kabushiki Kaisha | Date: 2016-03-02

Provided is a slide bearing 1 with which friction can be reduced and the total amount of effluent oil can be reduced. In the slide bearing (1) in which the halved members (2), (2) made by dividing the cylinder in two in the direction parallel to the axial direction are disposed vertically, the narrow grooves (33) are provided at an end of the lower halved member (2) in the circumferential direction from a mating surface on a downstream side of a rotation direction to a predetermined bearing angle (1) and peripheral edge parts (32a) are provided outside the narrow grooves (33) in an axial direction.

First closing member 2 and second closing member 3 close opening portions at both ends of cylindrical member 1 in an axial direction. Base 411 is housed in a space formed by cylindrical member 1, first closing member 2, and second closing member 3, and rotates around an axis in the same direction as the axial direction of cylindrical member 1. Resin layers 410 are formed on thrust surfaces of base 411. Groove C is a plurality of concentric circular grooves or a spiral groove formed on each resin layer 410, and the center of circles of the circular grooves or the center of a spiral of the spiral groove is different from the rotation center of base 411.

There is provided a slide bearing capable of preventing or reducing the likelihood of the occurrence of galling while being provided with an oil groove in its inner periphery. A cylindrical main bearing 2 is formed by combining an upper bearing 10 disposed on an upper side and a lower bearing 20 disposed on a lower side and rotatably supports a crank journal 1 a through an oil film between the cylindrical main bearing 2 and the crank journal 1 a. The lower bearing 20 includes an oil groove 23 formed in a low-load region L set in a range in which a pressure from the oil film is low on the inner periphery of the lower bearing 20.

Provided is a lubricant feed mechanism for a turbocharger, the mechanism that can reduce work of an oil pump while preventing an excessive supply of lubricant to a bearing part. The lubricant feed mechanism for a turbocharger 5, the mechanism of feeding lubricant to a bearing part 41 that rotatably supports a shaft 10 connecting a compressor wheel and a turbine wheel, includes: an oil supply passage 42 that guides the lubricant fed under pressure from the oil pump to the bearing part 41; and a flow control valve 50 provided to the oil supply passage 42 for adjusting the amount of the lubricant by throttling the flow passage of the lubricant based on a pressure of the lubricant flowing through the oil supply passage 42.
