一种发动机凸轮轴制造技术

本发明专利技术公开了一种发动机凸轮轴，在凸轮轴上设有机油油道，所述油道包括沿凸轮轴轴向延伸设置的主油道以及设置在凸轮轴轴颈上的副油道，该副油道连通主油道和轴颈外表面；VVT相位器设置在凸轮轴端部，靠近凸轮轴第一轴颈，主油道连通所述VVT相位器的油道。该凸轮轴的第一轴颈上的副油道与第一轴承盖上的油槽相连通，润滑油经第一轴颈的副油道进入主油道，一部分再经过其余各轴颈上的副油道流出，进行润滑，另一部分流入VVT相位器的油道，给VVT相位器供油。采用此技术方案，既满足了VVT相位器的供油，又保证了凸轮轴自身的润滑；此凸轮轴结构简单、紧凑，减轻重量，降低机加工艺难度，降低制造成本，节约发动机成本，大大提高发动机的性价比。

Engine camshaft

The invention discloses an engine camshaft, a camshaft in the engine oil channel, the oil passage comprises auxiliary oil passage along the cam shaft extending axially the main oil channel set and arranged in the cam shaft of the auxiliary oil passage is communicated with the main oil passage and the outer surface of the shaft neck; VVT phaser set in the end of the cam shaft, the cam shaft near the first shaft, the main oil passage communicated with the VVT phase for oil. The first auxiliary oil shaft neck of the camshaft on the road and the first on the bearing cover of oil tank is communicated with the lubricating oil through the oil first shaft enters the main oil passage, a part of oil after the rest of the shaft neck of the outflow tract, lubrication oil, another part of the inflow of VVT phase the oil is supplied to VVT phase. By adopting the technical scheme, not only to meet the supply of VVT phase, but also ensure the lubrication of camshaft itself; the camshaft has simple and compact structure, reduce weight, reduce machining difficulty, reduce manufacturing cost, saving the cost of the engine, greatly improve the engine performance.
