ft will be understood from the description above that the torque transmission coupling provided according to the present invention can be well applied to the revolution speed transmission line of each of various machines of a plant, the drive system of a general or industrial vehicle, a rotor drive system or the like if they need and match the properties of the torque transmission coupling.
Claim 4
Dependent Claim
405 words
A torque transmission coupling which comprises the following: (a) a first rotary shaft which is rotated by a driver and rotatively connected to a first rotary load means, (b) a second rotary shaft rotatively connected to a second rotary load means, (c) a hydraulic pump means which includes a first rotor having a prescribed form and disposed on said first rotary shaft so as to be rotated together therewith, and a second rotor disposed on said second rotary shaft so as to be rotated together therewith, and acts so that when a revolution speed difference has occurred between said first and second rotary shafts, said first and second rotors are relatively slided on a each sliding surface thereon by a relative rotation correesponding to said difference, to heighten the pressure of liquid-tightly interposed oil and then supply the pressure-heightened oil, (d) a multiple-disk clutch means which includes a group of engaging members disposed on said first rotary shaft so as to be rotated together therewith and be movable in the axial direction thereof relative to said first rotary shaft, and another group of engaging members which are disposed on said second rotary shaft so as to be rotated together therewith and are placed between the former engaging members so as to constitute a multiple-disk clutch, thus making it possible to engage both said groups of engaging members with each other to transmit torque, and (e) a pushing means which includes a hydraulic operating chamber, to which the pressure of the oil from said hydraulic pump means is applied through an oil pressure passage means, and a pushing member, which defines the inner surface of said hydraulic operating chamber and is moved depending on said oil pressure so as to move at least one of said groups of engaging members in such a direction as to reduce the distance between said groups of engaging members to engage said members with each other; and in which when said revolution speed difference has occurred between said first and second rotors of said hydraulic pump means, said oil pressure is produced by said relative rotation corresponding to said difference and is then applied to said hydraulic operating chamber through said oil pressure passage means to move said pushing member to engage both said groups of engaging members of said multiple-disk clutch means with each other to transmit said torque from said first rotary shaft to said second rotary shaft.
Claim 5
Dependent Claim
80 words
A torque transmission coupling according to the claim 1, wherein said hydraulic pump means is provided between said first rotary shaft and said second rotary shaft to produce the-oil pressure by the relative rotation between both said shafts to engage said multiple-disk clutch by said pushing member to transmit the torque; said clutch is provided between said first and second rotary shafts; and all these members and means of said torque transmission coupling are built in a transmission shaft system.
Claim 6
Dependent Claim
43 words
A torque transmission coupling according to the claim 2, wherein said hydraulic pump means, the pushing member and the multiple-disk clutch means, which are built in the transmission shaft system, are rotatably supported in an oil-tight secured casing in which oil is held.
Claim 7
Dependent Claim
39 words
A torque transmission coupling according to claim 1, wherein said hydraulic pump means comprises an oil pressure pump means for changing the volume between said first and second rotors by said relative rotation corresponding to said revolution speed difference.
Claim 8
Dependent Claim
39 words
A torque transmission coupling according to claim 4, wherein said oil pressure pump means comprises an oil pressure pump having a reciprocating member for reciprocating a cylinder in response to said relative rotation of said first and second rotors.
Claim 9
Dependent Claim
19 words
A torque transmission coupling according to claim 5, wherein said oil pressure pump comprises a radial plunger type pump.
Claim 10
Dependent Claim
140 words
A torque transmission coupling according to claim 1, further comprising an oil supply pump as an oil source to supply oil to said hydraulic pump means, which comprises a cam surface fixedly provided on the peripheral surface of said first rotary shaft; a cylinder provided in a casing and extending toward said cam surface; a helical spring disposed in said cylinder; and a plunger inserted in said cylinder, said plunger being moved back and forth synchronously with the rotation of said first rotary shaft to supply pressure oil to axial holes of the central portions of said first and second rotary shafts through an oil passage in said casing and a radial hole is said first rotary shaft, thereby providing a control function so as to enable said torque-transmitting property of the torque transmission coupling to be controlled from outside.
