Claims

[Claims for Utility Model Registration] 1. In a synchro counter gear device equipped with a forward gear or a reverse gear that engages with the synchronizer sleeve in accordance with the left and right movement of the synchronizer sleeve on the synchro counter shaft, the outer end surfaces of the forward gear and the reverse gear are provided with a first spiral oil groove for introducing lubricating oil toward the central shaft holes of the forward gear and reverse gear; and a second oil groove that communicates with the spiral oil groove in the hole wall of the central shaft hole. is provided to guide lubricating oil to the inner end surfaces of the forward gear and reverse gear, and further extends outward from the abutting portion of the synchronizer hub and the inner end surfaces of the forward gear and reverse gear, passing through the forward gear and reverse gear. 1. A lubricating device for a synchro counter gear device, characterized in that a lubricating device for a synchro counter gear device is provided with an oil passage to lead oil from the abutting portion to the outer circumferential areas of the forward gear and the reverse gear. 2. The synchro counter gear device according to claim 1, wherein at least two first spiral oil grooves are arranged separately in the circumferential direction on each of the outer end surfaces of the forward gear and the reverse gear. Lubrication device. 3. The second oil groove provided in the hole wall of the center shaft hole of the forward gear and reverse gear runs obliquely from the outer end surface side to the inner end surface side of each gear in a direction that generates an oil flow according to rotation. A lubrication device for a synchro counter gear device according to claim 1, characterized in that: 4 One pair of the first oil groove and the second oil groove provided in the forward gear and the reverse gear is provided for clockwise rotation, and the other pair is provided for counterclockwise rotation. A lubrication device for a synchro counter gear device according to claim 1, which is characterized by the above-mentioned.
