<p>PROBLEM TO BE SOLVED: To secure the minimum necessary amount of oil even during use in a low lubricating condition so as to prevent burning or the like by providing a regulating means for regulating the flow of lubricating oil for lubricating a conical roller bearing in the large diameter side of the outer ring inner periphery of the bearing in a conical roller bearing lubricating device used for various reduction gears. SOLUTION: For a pilot bearing section in the front side of a transmission, a conical roller bearing 3 having an outer ring integrally formed inside a main drive gear 1 is attached to one end of a main shaft 10. The main drive gear 1 is supported by a conical roller bearing 2. In this case, the conical roller bearing 3 includes, in the large diameter side of its inner peripheral surface 3a, a lip 4 having a lip part composed of a metallic ring and an elastic member. Thus, if traction is performed while the transmission is in a neutral state, a minimum lubricating condition is maintained by oil held inside the lip 4 and burning is satisfactorily prevented.</p> |
