PURPOSE:To achieve desired function with simple structure by separating the drive shaft into main shaft and inverted shaft then matching the power transmission of limited torque and a coupling system for coupling between said shafts to the axis of said shafts. CONSTITUTION:An inverted shaft 2 will form a compression chamber by means of two pages and cylinder 4 while limited of axial motion by means of front and rear sideboards 5, 6. It is coupled through a coupling means comprised of trnsmission pins 10, 10a for transmitting the drive force from main shaft 1 to the inverted shaft 2 while the strength is regulated to break down against excessive torque and a limiting pin 15 pressure inserted through a hole 14 conducting from the outer surface 12 of main shaft 1 to a circumferential groove 14 of a hole 13 into a shaft 11 extended from one end of the inverted shaft 2. Upon occurrence of exhaustion of oil to cause burning during operation, the transmission pins 10, 10a can not withstand but break down thereby driving force will not transmit to the inverted shaft 2 and main shaft 1 will continue rotation under no-load but it is blocked from removal by means of the limiting pin 15. |
