Description
技术领域technical field
本实用新型涉及发动机的曲轴、平衡轴、机油泵间的驱动布置结构，属发动机技术领域。The utility model relates to a drive arrangement structure among a crankshaft, a balance shaft and an oil pump of an engine, and belongs to the technical field of engines.
背景技术Background technique
目前，发动机的曲轴一般通过皮带或链轮来驱动机油泵和平衡轴总成(或平衡轴)，或者是曲轴驱动机油泵和平衡轴总成(或平衡轴)二者中的一个。这种布置方式的缺点是结构不紧凑、可靠性低，而且使用链条或皮带传动需要增加张紧器等零部件，提高了发动机的成本。At present, the crankshaft of the engine generally drives the oil pump and the balance shaft assembly (or balance shaft) through a belt or a sprocket, or one of the crankshaft drives the oil pump and the balance shaft assembly (or balance shaft). The disadvantage of this arrangement is that the structure is not compact, the reliability is low, and the use of chain or belt transmission requires additional components such as tensioners, which increases the cost of the engine.
利用曲轴同时驱动机油泵和平衡轴总成，若采用皮带传动，在发动机的曲轴一端安装一个皮带轮，机油泵和平衡轴总成的动力输入端也安装同类型的皮带轮，将三个皮带轮用一根皮带连接一起进行传动；若采用链条传动，在发动机的曲轴一端安装两个齿轮，机油泵和平衡轴总成的动力输入端也安装同类型的齿轮，将机油泵和平衡轴总成的动力输入端的齿轮用两根链条分别与发动机的曲轴一端安装的两个齿轮连接一起进行传动；以上两种方法都能够保证曲轴同时驱动机油泵和平衡轴总成进行工作。Use the crankshaft to drive the oil pump and balance shaft assembly at the same time. If belt transmission is used, install a pulley at one end of the crankshaft of the engine, and install the same type of pulley at the power input end of the oil pump and balance shaft assembly. Use one pulley for the three pulleys. If a chain transmission is used, two gears are installed at one end of the crankshaft of the engine, and the same type of gears are also installed at the power input end of the oil pump and balance shaft assembly, so that the power of the oil pump and balance shaft assembly The gear at the input end is connected to the two gears installed at one end of the crankshaft of the engine with two chains for transmission; the above two methods can ensure that the crankshaft drives the oil pump and the balance shaft assembly to work at the same time.
利用曲轴分别驱动机油泵和平衡轴总成，需在发动机的曲轴一端安装一齿轮，机油泵或平衡轴总成的动力输入端中的一个也安装同类型的齿轮，两个相同的齿轮啮合到一起进行传动，这样就保证了曲轴能够驱动机油泵和平衡轴总成中的一个进行工作，而另一个则通过皮带或链条与曲轴连接，使曲轴能够驱动其工作。以上方式是保证曲轴直接驱动机油泵和平衡轴总成两个中的一个进行工作，另一个通过间接方式驱动。The crankshaft is used to drive the oil pump and the balance shaft assembly respectively, and a gear needs to be installed at one end of the crankshaft of the engine, and one of the power input ends of the oil pump or the balance shaft assembly is also installed with the same type of gear, and the two identical gears mesh to Drive together to ensure that the crankshaft can drive one of the oil pump and balance shaft assembly to work, while the other is connected to the crankshaft through a belt or chain so that the crankshaft can drive it to work. The above method is to ensure that the crankshaft directly drives one of the oil pump and the balance shaft assembly to work, and the other is driven indirectly.
以上几种驱动方式，总的缺点是结构不紧凑、可靠性低，而且使用链条或皮带传动需要增加张紧器等零部件，提高了发动机的成本。The general disadvantages of the above several drive modes are that the structure is not compact and the reliability is low, and the use of chain or belt drive requires additional parts such as tensioners, which increases the cost of the engine.
