V-roller bearing and engine

Abstract

A bearing has an inner race that has separable inner sections. The inner race has an inner male protrusion and an inner female receptacle, and each inner male protrusion is mated with one of the inner female receptacles to form a unitary inner race. The bearing further has an outer race that has separable outer sections,. The outer race has an outer male protrusion and an outer female receptacle, and each outer male protrusion is mated with one of the outer female receptacles to form a unitary outer race. Further, the bearing has a plurality of rollers situated within a channel formed by engaging the inner race and the outer race.
