Abstract
A gear system is disclosed. The gear system has a structure in which oil churned by a gear is dispensed to at least one of a hollow space or a bearing, thereby effectively lubricating components. For example, the gear system includes a first shaft comprising a hollow space, a first gear arranged at an outer circumference of the first shaft, a second gear externally engaged with the first gear, a bearing arranged at the outer circumference of the first shaft, a housing surrounding the first gear and the second gear, and an oil guide plate disposed between the first shaft and the housing to dispense oil churned by the second gear to the hollow space of the first shaft and the bearing coupled to the first shaft.
