Abstract
An engine train structure is used to optimize the train arrangement, increase the reliability and reduce the cost. The technical scheme of the utility model is as follows: the engine train structure comprises a crankshaft gear arranged on an engine crankshaft, an oil pump driving gear arranged on an oil pump and a balance shaft idle gear arranged on the driving shaft (or balance shaft) of a balance shaft assembly; and the oil pump driving gear and the balance shaft idle gear are both meshed with the crankshaft gear. In the utility model, the oil pump driving gear and the balance shaft idle gear are both directly meshed with the crankshaft gear, thus the parts such as the tensioner and the slideway, used in the engine train structure driven by the belt and the chain wheel can be reduced, the structural arrangement is more compact and the reliability of the train can be increased. Meanwhile, as the gears are parts which are not required to maintain and replace, the use cost of the engine can be effectively reduced.
Description
Technical field
The utility model relates to the drive arrangement between the bent axle, trunnion shaft, oil pump of motor, belongs to technical field of engines.
Background technique
At present, the bent axle of motor generally comes driving machine oil pump and balance shaft assembly (or trunnion shaft) by belt or sprocket wheel, or in the two one of crank-driven oil pump and balance shaft assembly (or trunnion shaft).The shortcoming of this arrangement is that structure is not compact, reliability is low, and uses chain or belt transmission need increase component such as stretcher, has improved the cost of motor.
Utilize bent axle driving machine oil pump and balance shaft assembly simultaneously, if adopt belt transmission, bent axle one end at motor is installed a belt pulley, and the power intake of oil pump and balance shaft assembly is also installed belt pulley of the same type, three belt pulleys is connected with a belt carry out transmission; If adopt chain transmission, bent axle one end at motor is installed two gears, the power intake of oil pump and balance shaft assembly is also installed gear of the same type, and two gears that the gear of the power intake of oil pump and balance shaft assembly is installed with bent axle one end of motor respectively with two chains connect and carry out transmission; More than two kinds of methods can both guarantee bent axle driving machine oil pump and balance shaft assembly carry out work simultaneously.
Utilize bent axle driving machine oil pump and balance shaft assembly respectively, need one gear to be installed at bent axle one end of motor, one in the power intake of oil pump or balance shaft assembly gear of the same type is installed also, two identical gear engagement are to carrying out transmission together, so just guaranteed bent axle can the driving machine oil pump and balance shaft assembly in one carry out work, another then is connected with bent axle by belt or chain, makes bent axle can drive its work.With upper type is to guarantee that one in two of the direct driving machine oil pump of bent axle and the balance shaft assemblies is carried out work, and another drives by indirect mode.
More than several driving mode, total shortcoming is that structure is not compact, reliability is low, and uses chain or belt transmission need increase component such as stretcher, has improved the cost of motor.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, compact, reliability height, the engine wheel system structure that cost is low.
The alleged problem of the utility model realizes with following technical proposals:
A kind of engine wheel system structure, engine wheel system comprises the crankshaft gear that is installed on the engine crankshaft, be installed in the Oil pump drive gear on the oil pump and be installed in trunnion shaft idle pulley on the balance shaft assembly live axle (or trunnion shaft), and described Oil pump drive gear, trunnion shaft idle pulley all are meshed with crankshaft gear.
Above-mentioned engine wheel system structure, direction from external engine towards crankshaft gear, the right side that Oil pump drive gear is positioned at crankshaft gear on the lower side, the downside that the trunnion shaft idle pulley is positioned at crankshaft gear takes over, perhaps Oil pump drive gear be positioned at crankshaft gear the left side on the lower side, the trunnion shaft idle pulley is positioned at the downside of crankshaft gear.
Oil pump drive gear of the present utility model and trunnion shaft idle pulley all directly are meshed with crankshaft gear, and component such as the stretcher that has used when having reduced employing belt or chain wheel drive, slide rail make structural configuration compact more, have improved the reliability of train.Simultaneously, because gear is maintenance-free, free of replacement parts, also effectively reduce the user cost of motor.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 1, crankshaft gear; 2, Oil pump drive gear; 3, trunnion shaft idle pulley; 4, bent axle.
Embodiment
Referring to Fig. 1, crankshaft gear 1 direct driving machine oil pump and balance shaft assembly of the present utility model, train comprises crankshaft gear 1, Oil pump drive gear 2, trunnion shaft idle pulley 3.Crankshaft gear 1 is installed on the bent axle, and Oil pump drive gear 2 is installed on the oil pump, and trunnion shaft idle pulley 3 is installed on the balance shaft assembly (or trunnion shaft).Oil pump drive gear 2, trunnion shaft idle pulley 3 are meshed with crankshaft gear 1 simultaneously.Among Fig. 1, the right side that Oil pump drive gear 2 is positioned at crankshaft gear 1 on the lower side, the downside that trunnion shaft idle pulley 3 is positioned at crankshaft gear 1 takes over.The left side that also Oil pump drive gear 2 can be arranged at crankshaft gear 1 during concrete enforcement on the lower side, trunnion shaft idle pulley 3 is arranged at the downside of crankshaft gear 1.In design process, EQUILIBRIUM CALCULATION FOR PROCESS by bent axle, trunnion shaft and crankshaft-link rod rotatablely move the route calculation of process, gear meshing is calculated, determine that engine crankshaft gear 1 directly drives the power train arrangement of Oil pump drive gear 2 and balance shaft gear 3, guarantee simultaneously reliable driving machine oil pump of crankshaft gear and trunnion shaft (assembly).
