<p>PROBLEM TO BE SOLVED: To store lubricating oil in the rear of a rear side bearing mounted on an inner peripheral surface of a low gear of an auxiliary transmission part in a lubricating device for a multistage transmission having the auxiliary transmission part at the front stage of a main transmission part for varying rotational speed of a main shaft and supplying the lubricating oil to the bearing on the inner peripheral surface. SOLUTION: This lubricating device for the multistage transmission has the auxiliary transmission part 1 for switching the size of torque at the front stage of the main transmission part 2 for varying rotational speed of the main shaft 3 and supplies lubricating oil to a plurality of bearings 6, 7a and 7b provided on the inner peripheral surface of the auxiliary transmission part 1. A means 20 for storing lubricating oil is provided in the rear of the rear side bearing 7b mounted on the inner peripheral surface of the low gear 5 of the auxiliary transmission part 1. As a result, lubricating oil is stored in the rear of the rear side bearing 7b mounted on the inner peripheral surface of the low gear 5 of the auxiliary transmission part 1 to secure the lubrication.</p> |
