BEARING LUBRICATION STRUCTURE OF TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To supply clean oil to a bearing supporting the rotary shaft of a transmission and to improve durability.SOLUTION: A transmission T comprises a baffle plate 36 arranged in a mission case 11 so as to cover a first gear 32 and a second gear 30, an oil guide passage 39e is formed in the baffle plate 36 for supplying oil raked up by the first gear 32 and captured by the second gear 30 to a bearing 34, and foreign matter removing means 43 is provided between an oil inlet 39f and an oil outlet 39h of the oil guide passage 39e for removing foreign matter in the oil. The foreign matter removing means 43 can, therefore, remove the foreign matter just before the oil is supplied to the bearing 39, thereby making it possible to lubricate the bearing 34 with clean oil that does not contain the foreign matter and improve durability.
