Labor-saving time-saving torque amplifier

Abstract

The invention discloses a torque dupler that is both labor and time saving, which comprises an internal gear (1), a planetary gear (3) and an eccentric shaft (4) in a small-teeth-difference drive. In the internal gear (1), a wrench 11 is arranged; on the planetary gear (3), an output square hole 31 is arranged; on the ends of the eccentric shaft (4), a square end 41 is arranged; a wrench 61 with a square hole and looped on the square end 41 can rotate about the axial center. The internal gear (1) and the planetary gear (3) employ the gear pair of the small-teeth-difference drive. The gear ratio of the gear pair is equal to the magnification to be increased of the torque. As the torque dupler is provided with two wrenches 11 and 61, when the two wrenches rotate together, as the small-teeth-difference drive is locked into one part, the torque applied by the two wrenches on the places to be twisted is small, and the twisting time is fast; when one of the two wrenches is fixed and anotheris rotating, as the small-teeth-difference drive is developed into a reduction drive, the torque applied on the places to be twisted is bigger, and the twisting time is long. The torque dupler is both labor and time saving in operation.

Description

technical field [0001] The invention relates to occasions where various mechanisms in a machine need to increase the torque, in particular a labor-saving and time-saving torque booster. Since this torque booster is equipped with two hands, when the two wrenches rotate together as a whole, the torque applied to the occasion that needs to be twisted is small, and the twisting time is fast; when one of the two wrenches is fixed, the other rotates , the torque applied to the occasion that needs to be twisted is very large, and the twisting time is longer. Therefore, this torque booster can save labor and save time during operation. Background technique [0002] In the prior art, people use conventional wrenches to twist the occasions where various mechanisms in the machine need to be twisted. However, due to the limited moment arm of the wrench, it is impossible to increase the torque where the mechanism needs to twist. The torque booster in the labor-saving section uses two ...

AI Technical Summary

Problems solved by technology

Undoubtedly, this labor-saving torque booster overcomes the difficulty of twisting larger torque in conventional wrench twisting machines, especially for occasions that require extra large torque but the wrench cannot do it. Ratio, so that its mechanical gain is improved, and the torsion torque of the torque booster during the labor-saving section is greatly increased, which makes it impossible for conventional wrenches, but it can become a reality by using the torque booster during the labor-saving section
