Definitions

  • Figs. 1 & 2 respectively show a part-sectional elevation, and a sectional plan view of a first embodiment 100 of torque wrench in accordance with the present invention.
  • the torque wrench 100 comprises a longitudinally elongated hollow tubular body 102, a torque limiting/indicating mechanism 104 at the left end of the wrench 100, and a handle 106 at the right end of the wrench 100.
  • the torque limiting/indicating mechanism 104 is shown to an enlarged scale in Fig. 3).
  • the other end of the component 114 is formed as a rotary cam 118 having a camming profile 120 which will subsequently be explained in detail.
  • the socket 116 and the cam 118 are formed integrally, with an intervening hole 122 (see especially Fig. 4) by which the component 114 is rotatably mounted on the pivot pin 110.
  • the right or inboard end of the trunnion 126 (i.e. the end opposite the bearing 132) is formed as a reduced-diameter spigot 138 for mounting one end of a spacer tube 140.
  • the other (right) end of the spacer tube 140 is fitted with a combined slide support and spring seating 142 which serves both to provide seating for the left end of a coiled compression spring 144, and sliding support against the bore of the wrench body 102 for the tube 140 and the spring 144.
  • the right end of the spring 144 seats on a further slide support 146 whose position along the bore of the tubular wrench body 102 is determined by a screw-threaded adjustment member 148.
