Embodiment Construction

[0012] Referring now to the drawings, and in particular to figure 1 , figure 1 A vehicle 10 is shown having a power generation device 12 and a power transmission device 14 . Vehicle 10 is shown as an agricultural vehicle, although it is recognized that other vehicles such as construction vehicles, forestry vehicles, industrial vehicles, mining vehicles, and the like may serve as platforms for incorporating embodiments of the gearbox of the present invention. Power generation device 12 may be a diesel engine that provides mechanical rotational motion to power transfer device 14 . The power transmission device 14 may be a gearbox or other similar device having rotating gears for transferring torque and converting the torque to different speeds and / or directions.

[0013] Now, additionally referring to figure 2 with 3 , figure 2 with 3 A detail of the power transfer device 14 is shown, which includes a housing 16 with a lubricating oil passage 18 therein. Lube passage 18...

Abstract

The inventiin discloses a power generation device and a power transmission device. The power transmission device is connected to the power generation device. The power transmission device comprises at least one rotating component which has an opening, and splines extend to pass through the opening. The rotating component can rotate around the splines and is equipped with a joint component facing the splines. A plug is positioned in the opening and a hole passes through the plug.

Description

technical field [0001] The present invention relates to a power transfer box lubrication device, and more particularly, to a gearbox spline lubrication device. Background technique [0002] Power transmission devices, such as transmissions or pump drive gearboxes, are typically lubricated by partially submerging at least one gear in a sump of lubricating oil, which causes the lubricating oil to splash into the interior of the box. There may even be protrusions from parts of the gear, causing more oil to splash inside the gearbox. This is a stochastic type of lubrication that has been applied in many transmission types and it is assumed that the oil will eventually get where it is needed by being randomly splashed onto the interior of the gearbox or onto the components moving within it. [0003] In a broad sense, a gearbox can be thought of as a device that converts speed, torque, into another speed and torque, and is typically applied in vehicles powered by an engine, a sou...
