Lubricating structure for coupling part

Abstract

Abstract PURPOSE:To perform lubrication and cooling so efficiently as well as to simplify a structure in a power transmission by forming a coupling chamber in a case covering a coupling part of the power transmission and also forming a feed oil port and a drain oil port in this case. CONSTITUTION:Hydraulic fluid (drain oil) discharged to the inside of a drain oil passage 8a, after being used for operation of hydraulic equipment 8, flows into a coupling chamber 7 from a feed oil port 7a, and it is exhausted to the outside of the drain oil port 7b after a coupling part 6 housed in the coupling chamber 7 is lubricated and cooled. And, this exhausted hydraulic fluid flows into a coupling chamber 10 from the feed oil port 7a (the drain oil port 7b), and it overflows from a drain oil port 10b after lubricating and cooling a coupling part 14 housed in a coupling chamber 10. Since the hydraulic fluid driving the hydraulic equipment 8 is used as lubricating oil in this way, a circulating route of oil so far required with two systems will get off with one system, and structural simplication in a power transmission and reduction in cost are thus promotable.
