Title: Power take-off mechanism for vehicle transmission
Inventor: TSURUOKA TAKUHIRO
IPC: F16D7/02
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To avoid the damage of a transmission system when an excessive load is applied and to automatically cut off the power to a mounted object by externally inserting the tube section of a flange joint to a power take-off shaft, and fixing the extracting shaft and the coupling section of the tube section with an adhesive. SOLUTION: A coupling section 15 between the small-diameter shaft section 7b of a power take-off section 7 and the tube section 9 of a flange joint 10 is coupled with a round shaft and a round hole, and the coupling section 15 is connected by an anaerobic adhesive. The anaerobic adhesive enters the fine gaps of the coupling section 15, and it is hardened by a polymerization reaction when it is shielded from air, therefore handling is simplified in assembling. The axial movement of the flange joint 10 is suppressed by a washer 12 and a bolt 13 as the release stop measure of the flange joint 10.  The transmission torque between the take-off shaft 7 and the flange joint 10 depends on the shearing strength of the adhesive, and various torque can be coped with by setting the type of the adhesive and the coated area in advance, thereby the damage of a transmission system from the take-off shaft 7 to a hydraulic pump on a mounted object side can be avoided.
