    摘要： A slide bearing configured to support a crankshaft or a crankpin includes: a halved upper bearing body which is disposed on the upper side in an up-and-down movement direction of a piston; and a halved lower bearing body which is disposed on the lower side in the up-and-down movement direction. The upper bearing body includes an upper sliding surface having an upper oil groove disposed along a circumferential direction of the upper sliding surface at a central portion in an axial direction of the upper sliding surface. The lower bearing body includes a lower sliding surface that configures, along with the upper sliding surface, a cylindrical sliding surface that rotatably supports the crankshaft or the crankpin through an oil film, and the axial width of the lower sliding surface is narrower than the axial width including the oil groove of the upper sliding surface.

    摘要： The compressor comprises: a crankcase (10) carrying a cylinder (20) and a bearing hub (40) having a first and a second end portions (40a, 40b) and defining a radial bearing (41), in which is housed a crankshaft (50); and a connecting rod (60) coupled to a piston (30) housed in the cylinder (20) and having a larger eye (61) mounted in an eccentric end portion (55) of the crankshaft (50). Each of said end portions (40a, 40b) is defined by a bushing extension (45, 46) affixed in the interior of the bearing hub (40) and having an end portion (45a, 46a) projecting outwards from the bearing hub (40), in order to be elastically and radially deformed when pressed by a confronting portion of the crankshaft (50), which presents coaxiality deviation in relation to the axis (X1) of the radial bearing (41).

    摘要： A bottom bracket assembly of a bicycle that cooperates in an eccentric or off-center manner with a bottom bracket shell of a bicycle frame. The eccentric bottom bracket assembly has a cylindrical insert with an off-centered opening for receiving a spindle that connects to cranks of the crankset. Rotating the cylindrical insert repositions the off-centered opening relative to at least the longitudinal direction of the bicycle and thus can be used to adjust the tension in the flexible drive member of the bicycle. A worm gear arrangement provides controlled manipulation of the position of the insert relative to the bicycle frame.

    摘要： An internal combustion engine includes a split crankcase with spaced-apart journal walls. Each journal wall has a bearing hole formed therein. The engine also includes rotary bearings for supporting rotary movement of a crankshaft. A backlash-absorbing mechanism is situated proximate a first one of the rotary bearings, for cushioning radial movement of an outer bearing race. Axial movement-restraining structure is also provided adjacent the outer race, for limiting axial movement thereof. The axial movement-restraining structure may include an engaging groove provided in an inner circumferential surface of the outer race, and a restraining clamp member operatively attached to a surface of the crankcase. The restraining clamp member may include a hook portion which engages with the engaging groove of the outer race. The axial movement-restraining structure allows at least one of the crankshshaft support bearings to be a roller bearing or a needle bearing, instead of a ball bearing.
