の潤滑装置に関する。[Detailed Description of the Invention] The present invention provides a transmission lubricating device, more specifically, a transmission lubrication device that supplies lubricating oil in the transmission case to movable parts in the extension case between the transmission case and the extension case. This invention relates to a transmission lubrication device equipped with an oil supply gutter.

内の可動部分に供給するごとくしている。 Generally, the movable parts in the extension case are located above the oil level of the lubricating oil stored in the transmission case, making it difficult to lubricate the movable parts. A supply gutter is provided so that the lubricating oil splashed up by the gears in the transmission case is received by the oil feed gutter and supplied to the movable parts in the extension case.

動部分の一方が潤滑出来なくなる虞れもあつた。 Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 162357/1983, a through hole is provided in the middle of the oil supply gutter, and a portion of the lubricating oil flowing on the gutter is leaked from the through hole. Devices that supply lubricating oil to multiple moving parts have been developed, but with the structure described above, it is difficult to supply the appropriate amount of oil to each moving part, and it is difficult to supply lubricating oil to each moving part. There is a tendency for supply to be insufficient for the moving parts of the
In addition, especially when the flow rate of lubricating oil flowing through the gutter decreases, there is a risk that the entire amount will flow down from the through hole, making it impossible to lubricate one of the movable parts.

に供給されることになるのである。 As described above, according to the present invention, a partition wall is provided along the length of the oil supply gutter to form two independent oil passages, and two movable parts in the extension case are connected via these oil passages. Since lubricating oil is supplied to each part individually, there is no risk of oversupply or undersupply of lubricating oil to either one of the moving parts, as was the case in the past, and the lubricating oil is always supplied to both moving parts. This made it possible to reliably supply a sufficient amount of lubricating oil to each. Further, a rib 64 having an end surface that can come into contact with the mating surface 10 of the transmission case 1 is provided on the lower surface of the oil supply gutter 6 on the extension case 2 side, and is located on the transmission case 1 side. The partition wall 60 is made higher than the oil supply gutter 6, and a receiving part 63 is provided, so that the end surface of the receiving part 63 on the extension case 2 side can come into contact with the mating surface 20 of the extension case 2. , the oil supply gutter 6 is connected to the transmission case 1 and the extension case 2.
Since the oil supply gutter 6 is fixed between the mating surfaces 10 and 20, the oil supply gutter 6 is reliably fixed in a predetermined position by the ribs and the receiving part. Compared to the gutter, a larger amount of lubricating oil is received by the oil supply gutter 6, and the lubricating oil is individually and accurately supplied to the two movable parts described above.
