Problems solved by technology

For example, interrupted movement of the fastener rotation due to the reciprocating motion of the piston can cause the fastener to rotate slowly
The reciprocating motion of the piston can also cause hammering within the wrench, which creates unwanted vibrations and creates noise
Additionally, conventional hydraulic wrenches are only useful under certain conditions (e.g., in dry and / or clean ambient conditions) and require frequent maintenance (e.g., for cleaning and replenishing or changing internal lubrication)

Embodiment Construction

[0020] figure 1 and figure 2 Variations of an exemplary torque wrench ("wrench") 10 are described that may be used to loosen or tighten fasteners (eg, bolts having heads with internal and / or external engagement features - not shown) . The wrench 10 can generally be divided into an input 12 and an output 14 . Input 12 may be configured to receive a continuous torsional input (eg, from a manually operated lever or from an electric, hydraulic or pneumatic motor), which is then converted to a continuous torsional output at output 14 . The twist input can be generally aligned with the first axis 16 of the wrench 10 , and the twist output can be generally aligned with the second axis 18 that is substantially (eg, within 0-10°) perpendicular to the first axis 18 . The input 12 may include a mating interface (eg, socket, spline, Torx or square root, etc.) 20 configured to mate with a corresponding mating interface of a rod or motor and receive a torsional input. The output 14 may...

Abstract

A torque wrench is disclosed for use in rotating a fastener. The torque wrench may include an input end configured to receive a torsional input, a housing, and a gear train disposed inside the housingand operatively driven by the torsional input. The torque wrench may also include a torque multiplier disposed inside the housing and connected to the gear train, and an output end operatively drivenby the gear train to produce a torsional output.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Patent Application No. 15 / 469,160, filed March 24, 2017. The entire content of the above application is hereby incorporated by reference. technical field [0003] The present disclosure relates to a torque wrench, and more particularly, to a torque wrench with a continuous rotational drive. Background technique [0004] A torque wrench is a tool used to apply a torque wrench on a fastener (eg, on a bolt head or nut with specially designed inner and / or outer surfaces) to loosen or tighten the fastener. In some embodiments, the torque wrench is powered. For example, torque wrenches can be hydraulic, pneumatic or electric. In other examples, a torque wrench is manually manipulated. [0005] Conventional torque wrenches are ratchet-type wrenches in which reciprocating motion (eg, of an internal piston) rotates the fastener through a narrow angle (eg, approximately...
