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
The invention belongs to Structure of Internal-Combustion Engine, be specifically related to a kind of oil pump transmission system of DENG.
Background technique
As everyone knows; The motor operation need provide stable engine oil pressure that the parts that turn round are lubricated the ability proper functioning; If engine oil pressure is not enough, will increase the wearing and tearing of transmission part and reduce working life, so the rational lubrication System Design of motor is very crucial.The oil pump transmission system that present diesel engine generally adopts is that oil pump is fixed in the gear chamber, through the rotation generation oil pressure of built-up gear in the gear chamber, machine oil is transported to each running position of motor.The front end of this drive mechanism oil pump filler opening generally need connect the machine oil that long fuel sucking pipe just can be drawn onto oil sump, so the oil transportation resistance can reduce the pump oil ability of oil pump.Because the diesel engine space outerpace is very narrow, oil pump is installed in motor head, can increase the design and the difficulty of processing of gear chamber, gear chamber cover in addition.To this technological deficiency, the invention provides a kind of oil pump transmission system of new structure.This structure oil pump directly is in the oil sump, has avoided fuel sucking pipe to the loss that engine oil pressure causes, and has improved the pump oil ability of oil pump, has also reduced the design and the difficulty of processing of motor head gear chamber and gear chamber cover simultaneously.
Summary of the invention
The objective of the invention is, provide a kind of oil pump is directly placed the diesel engine lubricating oil conveying system in the oil sump, thereby effectively improve the pump oil ability of engine oil pump.
Technological scheme of the present invention is that DENG oil pump transmission system comprises: camshaft, oil pump drive spindle, a pair of helical gear, transmission shaft-cup, main gear shaft, oil pump, oil sump and camshaft gear wheel etc.Camshaft is connected through a pair of intermeshing helical gear with oil pump drive spindle, and the horizontal side helical gear is connected with camshaft; The vertical side helical gear is connected with oil pump drive spindle.Oil pump drive spindle one end is an optical axis, and optical axis inserts the transmission shaft-cup; The other end is connected with the main gear shaft of oil pump through spline structure, and the spline connecting end is provided with spline housing.Oil pump places in the oil sump, and crankshaft of diesel engine gear driven camshaft gear wheel rotates, and camshaft turns round according to valve timing.
Its working principle is when camshaft rotates, to rotate through the oil pump drive spindle of helical gear drive with its engagement; Because oil pump drive spindle is connected through spline structure with master's (moving) gear shaft of oil pump; So the gear train in the driving gear shaft rotating band motivation oil pump rotates, the machine oil in the oil sump is transported to each position of motor through main oil gallery.
The beneficial effect of characteristics of the present invention and generation is: oil pump directly is arranged in the oil sump, directly contacts with machine oil, has eliminated the former flow resistance that fuel sucking pipe causes that is provided with, and has effectively improved pump oil ability.The oil pump transmission system is arranged in the body side, does not adopt present motor that oil pump is arranged in the structure of motor head, has reduced the design and the manufacture difficulty of engine gear case and gear chamber cover.
Description of drawings
Fig. 1 is a structural principle sketch of the present invention.
Fig. 2 for the present invention in the motor mounting point schematic diagram of mechanism.
Embodiment
Following with reference to accompanying drawing and combine embodiment that the present invention is further described.DENG oil pump transmission system, its structure characteristic is: camshaft 1 is connected through a pair of intermeshing helical gear with oil pump drive spindle 2, and horizontal side helical gear 3 is connected with camshaft; Vertical side helical gear 4 is connected with oil pump drive spindle.Oil pump drive spindle one end is an optical axis, and optical axis inserts transmission shaft-cup 5; The other end is connected with the main gear shaft 6 of oil pump through spline structure, and the spline connecting end is provided with spline housing 7.Oil pump 8 places in the oil sump 9.Crankshaft of diesel engine gear driven camshaft gear wheel 10 rotates, and camshaft turns round according to valve timing.Transmission shaft-cup 5 is provided with oil duct near a side of vertical side helical gear 4, rely on the helical gear body with oily splash lubrication oil pump drive spindle.Another effect of transmission shaft-cup is with whole oil pump transmission system sealing.
This oil pump transmission system at first is inserted in spline housing the spline connecting end of oil pump master (moving) gear shaft when assembling, and the oil pump main gear shaft is inserted corresponding transmission axis hole in the engine body 11, uses bolton.An other side in transmission shaft hole is inserted oil pump drive spindle on engine body simultaneously, makes the engagement of transmission shaft helical gear and camshaft helical gear.After splined end is inserted spline housing, measure the distance of oil pump drive spindle and body transmission axis hole mounting plane, the axial clearance of adjustment oil pump drive spindle is controlled between the 0.2-0.3mm.Fitting machine oil pump and transmission shaft-cup then; Specifically be that optical axis is inserted in the transmission shaft-cup; The oil duct that makes the transmission shaft-cup is near the helical gear side of camshaft, leans on helical gear splash lubrication transmission shaft, at last through the transmission shaft-cup with whole oil pump transmission system fixing seal.
This DENG oil pump transmission system is good at effect on bavin 4102 h type engine hs, has satisfied user's demand.
