Abstract
The utility model relates to a support structure for a crankshaft of a 195 model diesel engine. Original double-sliding friction of the crankshaft is changed to rolling friction and sliding friction. A shaft neck at one end of the crankshaft forms a sliding fit with a bearing hole on a cylinder body of the diesel engine through a bearing bush. The other end of the crankshaft forms a rolling fit with another bearing hole on the cylinder body of the diesel engine through a rolling bearing. The utility model reduces the running resistance of the diesel engine and improves the starting performance of the engine, and the oil consumption is reduced.
Description
The utility model relates to diesel engine, particularly the supporting structure of 195 Diesel Engine Crankshaft.
The supporting structure of existing crankshaft of diesel engine is two sliding supported conditions, and surface friction drag is big, thereby starting performance is good for a long time, power consumption, oil consumption height.
The purpose of this utility model is to provide a kind of little crankshaft supporting structure that rubs.
Solution of the present utility model: an end journal of bent axle is slidingly matched by a bearing hole on bearing shell and the diesel engine cylinder block, and the other end axle journal of bent axle rolls with another bearing hole on the diesel engine cylinder block by rolling bearing and cooperates.
Adopt the utility model, the former pair of sliding friction that changes bent axle is a roll and a slide friction, lowered the running resistance of diesel engine, improved the starting performance of motor, reduced oil consumption.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Left axle journal 1 place and main axle bush 2 activities of bent axle match, and main axle bush 2 is fixed in the left bearing hole of diesel-engine body 3; The right axle journal 10 of bent axle and the inner ring close-fitting of rolling bearing 5, the inner ring of rolling bearing 5 is respectively by packing ring 11 and back-up ring 7 location, the outer ring of rolling bearing 5 is fixed in the main bearing seat 6, one side of rolling bearing 5 outer rings is against on the main bearing seat 6, the another side is by thrust plate 4 axial restraints, between main bearing seat 6 and the bent axle 9 crank shaft oil seal 8 is housed, main bearing seat 6 is fixed in the right bearing hole of diesel-engine body 3.
Claims (1)
