Embodiment Construction

[0009] The present invention will be further described below with reference to the accompanying drawings and in conjunction with the embodiments. The diesel engine oil pump transmission system has the following structural features: the camshaft 1 is connected to the oil pump transmission shaft 2 through a pair of intermeshing helical gears, the horizontal side helical gear 3 is connected to the camshaft; the vertical side helical gear 4 is connected to the oil pump transmission shaft . One end of the transmission shaft of the oil pump is an optical shaft, and the optical shaft is inserted into the transmission shaft cover 5; The oil pump 8 is placed in the oil pan 9 . The crankshaft gear of the diesel engine drives the camshaft gear 10 to rotate, and the camshaft operates according to the valve timing. The transmission shaft cover 5 is provided with an oil passage near the side of the vertical side helical gear 4, and relies on the oil splash carried by the helical gear body...

Abstract

The invention discloses an oil pump driving system for a diesel engine, which is structurally characterized in that a camshaft is connected with an oil pump driving shaft through a pair of mutually engaged bevel gears, a horizontal bevel gear is connected with the camshaft, a vertical bevel gear is connected with the oil pump driving shaft, a polished shaft is arranged at one end of the oil pump driving shaft and inserted into a driving shaft cover, the other end of the oil pump driving shaft is connected with a main gear shaft of an oil pump through a spline structure, a spline connecting end is provided with a spline sleeve, the oil pump is arranged in an oil pan, a crankshaft gear of the diesel engine drives a camshaft gear to rotate, and the camshaft runs according to valve timing. The oil pump is directly arranged in the oil pan and directly contacts with oil, flow resistance caused by an original oil suction pipe is eliminated, and oil pumping capacity is effectively improved. The oil pump driving system is arranged on the lateral face of an engine body without adopting the structure of arranging an oil pump at the front end of an engine at present, so that difficulty in designing and manufacturing a gear chamber and a gear chamber cover of the engine is reduced.

Description

technical field [0001] The invention belongs to the structure of an internal combustion engine, in particular to an oil pump transmission system of a diesel engine. Background technique [0002] As we all know, the engine needs to provide stable oil pressure to lubricate the running parts in order to work normally. If the oil pressure is not enough, it will increase the wear of the transmission parts and reduce the service life. Therefore, a reasonable engine lubrication system design is very critical. At present, the oil pump transmission system commonly used in diesel engines is to fix the oil pump in the gear chamber, and the oil pressure is generated through the rotation of the combined gears in the gear chamber to transport the oil to various operating parts of the engine. The front end of the oil pump inlet of this transmission structure generally needs to be connected to a long oil suction pipe to suck the oil from the oil pan, so the oil delivery resistance will redu...
