TRANSMISSION DEVICE AND POWER UNIT
Document Type and Number:
WIPO Patent Application WO/2023/162154
Kind Code:
A1
Abstract:
Provided is a transmission device (T) in which an input gear (Gi) rotated by motive power from a motive power source (M) and a counter gear (Gc) that rotates about an axis parallel to the rotation axis of the input gear are in mesh with each other and are disposed inside a transmission case (Ct), wherein the transmission case (Ct) has a first oil-catching part (H1) capable of catching oil splashed from the input gear (Gi), an oil inlet (H1i) of the first oil-catching part (H1) is located on the front side of the input gear (Gi) in the forward rotation direction on a common tangent line between the pitch circles of the input gear (Gi) and the counter gear (Gc) when viewed from the axial direction of the input gear (Gi), and the transmission case (Ct) is provided with a lubricated part that is lubricated with the oil caught in the first oil-catching part (H1). As a result, even when the input gear rotates at a high speed, oil splashing in great amounts from the input gear after the input gear and the counter gear mesh together can be efficiently caught in the first oil-catching part and supplied to the lubricated part, and the splashed oil from the input gear can be effectively used for lubricating the lubricated part.
