The design and effect of the eccentricity is described below by way of example.
The right deflection on the supporting frame 807 causes the center line of the circular spindle 704 and the input shaft 707 to form a certain eccentricity, see fig. 4 that the transmission mechanism 2 generates a vertical downward pulling force F after passing through the reversing mechanism2 'Pulling the rod around the axis, the end of the rod 703 being single-claw 706 along the hub 702 perform the cutting-in and cutting-out movements. Hub shear force FCAt an angle of 15 degrees to the rod 703. When only the force generated at the tangent point is calculated without considering other factors,
wherein, F cShear forces generated for tie-rods and hub notches, F AIs the horizontal component of the pull rod 703,

Referring to FIG. 5, to reduce the single pawl 706 cut-in and cut-out resistance of the tie rod 703, the angle of the mouth of the dovetail groove 705 of the reducer hub 702 is reduced. In a preferred embodiment, the groove edges of the dovetail groove 705 are angled at an angle ranging between 13 degrees and 19 degrees (inclusive of the values at the ends of the range) and preferably at an angle of 13 degrees to the centerline of the dovetail groove 705.
Referring to fig. 7, a nut 801 may be welded to the back of the single jaw 706. Since the structure of the pull rod 703 is rotated leftwards in a free state, the claw of the pull rod cannot lock the brake hub 702, and in order to ensure the locking of the input shaft 707 when the reduction gearbox is transported separately, the single-claw end of the pull rod 703 is welded with a nut 801 which is locked in the positioning sleeve 803 through the adjusting screw 802.
