SLIDE BEARING AND LUBRICANT FEED MECHANISM HAVING THE SAME

摘要

There is provided a slide bearing capable of preventing or reducing a temperature increase in lubricant. A cylindrical main bearing is formed by combining a pair of upper bearing and lower bearing and rotatably supports a crank journal. The lower bearing includes a downstream crush relief formed at a downstream end in the rotation direction of the crank journal in an inner periphery of the lower bearing; and an oil groove formed in the inner periphery of the lower bearing so as to communicate with the downstream crush relief.

主权项

1. A slide bearing having a cylindrical shape, comprising a pair of upper and lower semi-cylindrical bearings in combination,
the slide bearing rotatably supporting a shaft member, wherein at least one of the pair of upper and lower semi-cylindrical bearings comprises a crush relief formed at at least one of upstream and downstream ends in the rotation direction of the shaft member in an inner periphery of the semi-cylindrical bearing; and an oil groove formed in the inner periphery of the semi-cylindrical bearing so as to communicate with the crush relief.
