Abstract

The invention relates to a gear train layout structure for driving a fuel pump. The gear train layout structure may include a fuel pump configured to pressurize fuel and to supply the pressurized fuel to an engine, a pump shaft, a driven gear for rotating the pump shaft, a driving gear to drive the driven gear, a first balance shaft and a second balance shaft respectively mounted at a front and a rear of a crankshaft of the engine for balancing the engine and attenuating vibration of the engine, a first balance gear and a second balance gear, a crank gear fixedly mounted on a side portion of the crankshaft, and at least one connecting rod connecting the crankshaft and a piston for rotating the crankshaft.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0148644 filed on October 29, 2014, the entire contents of which are incorporated herein for all purposes of such reference. technical field [0003] The present application relates to a gear train arrangement. More particularly, the present application relates to a gear train arrangement for driving a fuel pump. Background technique [0004] Typically, the crankshaft is precisely designed to balance possible vibrations that may occur due to the reciprocating motion of the pistons in the engine cylinders. To balance said vibrations, the crankshaft may be provided with counterweights on opposite sides of the crank arms. [0005] Even though most of the engine vibration is damped by the crankshaft's balance weight, engine vibration may not be completely eliminated. So, to balance the remaining vibrations of the engine, the crankshaft can have a...
