Abstract

The invention discloses a crankshaft structure of a V-shaped 16-cylinder engine. Two ends of a crankshaft are respectively a free end and a power output end; a first crank throw, a second crank throw, a third crank throw, a fourth crank throw, a fifth crank throw, a sixth crank throw, a seventh crank throw and an eighth crank throw are arranged from the free end to the power output end in sequence; horizontal first oil ways are respectively formed in main bearing journals on two sides of a first connecting rod journal and an eighth connecting rod journal; the first oil ways are perpendicular to the center axes of the main bearing journals; and vertical second oil ways are respectively formed in main bearing journals on two sides of a third connecting rod journal, a fourth connecting rod journal, a fifth connecting rod journal and a sixth connecting rod journal. The oil way arrangement is convenient for machining; main bearings and connecting rod bearings can be fully lubricated; and the lubricating effect of journal bearings is improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a crankshaft structure of a V-type 16-cylinder engine. Background technique [0002] The torsional vibration amplitude of the crankshaft of the existing V-type 16-cylinder engine is large, and the strength performance of the crankshaft is poor, and the oil supply capacity is poor, and the oil passage arrangement is difficult and difficult to process. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a crankshaft structure of a V-type 16-cylinder engine, thereby overcoming the existing shortcomings of the crankshaft with large torsional v...
