To suppress seizure or fatigue damage of a tooth surface due to insufficient lubrication of each gear in a reduction reverser 8 including a housing 9 serving as an oil tank in which at least a pair of mutually engaging gears 56, 32 is stored.SOLUTION: In a reduction reverser, an extension oil passage 66 branches from a lubricant passage 35 in which a working fluid in a housing 9 circulates as a lubricant; and a jetting part 67 for jetting the working fluid as a lubricant toward an engaging part 88 between gears 56, 32 from an upstream side in a normal rotation direction of the gears 56, 32 is installed on an outlet side of the extension oil passage 66.SELECTED DRAWING: Figure 5
【課題】相互に噛み合う少なくとも一対のギヤ56,32が収容されるオイルタンクとしてのハウジング9を備える減速逆転機8において、前記各ギヤの潤滑不足による歯面の焼き付きや疲労損傷の発生を抑制する。【解決手段】ハウジング9内の作動油が潤滑油として流通する潤滑油路35から延長油路66を分岐させる。延長油路66の出口側には、ギヤ56,32同士の正転方向上流側からギヤ56,32同士の噛み合い部88に向けて潤滑油としての作動油を噴出する噴出部67を設ける。【選択図】図5
