Abstract

Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.

First claim

What is claimed is:

1 . A torque application tool comprising:
a housing having opposing first and second ends and first and second housing portions with respective first and second stiffnesses, wherein the second stiffness is greater than the first stiffness; an input rotatably coupled to the housing at the first end and adapted to receive a torque; and an output rotatably coupled to the housing at the second end and operatively coupled to the input to receive the torque from the input; and a support coupled to the first portion between the first and second ends, the support extending perpendicular from the first portion.

2 . The tool of claim 1 , further comprising a base coupled to the support opposite the first portion.

3 . The tool of claim 1 , further comprising first and second sprockets respectively coupled to the input and output.

4 . The tool of claim 3 , wherein the first and second sprockets are coupled together by a chain.

5 . The tool of claim 1 , further comprising first and second gears respectively coupled to the input and output.

6 . The tool of claim 5 , wherein the first and second gears are coupled with a gear train.

7 . The tool of claim 1 , wherein the input includes a receiving portion.

8 . The tool of claim 1 , wherein the output includes a drive.

9 . The tool of claim 1 , wherein the housing further includes a first side opening, and further comprising a first cover that encloses the first side opening.

10 . The tool of claim 9 , wherein the housing further includes a second side opening, and further comprising a second cover that encloses the second side opening.

11 . The tool of claim 9 , wherein the first cover is composed of a cover material and the housing is composed of a housing material, and wherein the cover material is more flexible than the housing material.

12 . A method of applying torque comprising:
providing a tool having a housing with a first portion having a first stiffness and a second portion having a second stiffness greater than the first stiffness, the tool further including an input adapted to receive a torque and transfer the torque to an output, the output further adapted to transfer the torque; coupling a support to the first portion; and applying the torque to the input and allowing the torque to be transferred from the output.
