Title:
4サイクルエンジンの潤滑構造
Document Type and Number:
Japanese Patent JP4302800
Kind Code:
B2
Abstract:
The inside of a crankcase for a four-cycle engine is divided by a bulkhead into a crank chamber and a transmission chamber. A crankshaft and a balancer shaft for suppressing engine vibrations by rotating in accompaniment with rotations of the crankshaft are rotatably attached within the crankshaft, and the balancer shaft is driven by the crankshaft via a gear set housed within the crank chamber. Meshing parts of a gear set can be sufficiently lubricated by oil mist without a special lubricating structure being required. Furthermore, the engine can be decreased in size without forming a sealed space for lubricating the gear set.
