<p>A torque multiplier assembly (A) that is portable, compact, and may be easily and conveniently disposed adjacent a nut, bolt or similar threaded elements to removably engage the same. The torque multiplier assembly (A) when so engaged is adapted to exert a first relatively high maximum torque of predetermined value on the nut, bolts or similar elements to initially rotate the same from binding threaded engagement or perform the final tightening of the nut, bolt or rotatable element. The torque multiplier assembly (A) is manually actuated by the use of an elongate torque wrench (B) of a type that is commercially available and may be adjusted to supply any one of a number of maximum torque. The desired maximum torque supplied by the elongate torque wrench (B) is relatively low, normally not over fifty foot pounds, and is visually indicated on a calibrated scale (14,15) that forms a part of the torque wrench (B). The maximum torque supplied by the torque wrench (B) is transferred to the multiplier assembly (A) with the torque output of the multiplier assembly (A) being the torque input of the torque wrench multiplied by a factor that is inherent to the specific gear structure of the multiplier assembly (A).</p> |
