Embodiment Construction

[0022] For example, refer to figure 1 A and 1B, there are shown perspective views of an embodiment of the invention as non-reaction arm apparatus 1A and 1B for tightening and loosening industrial threaded fasteners 20 with minimal galling, such The industrial threaded fastener 20 has a nut 21 , a washer 22 and a stud 23 . Devices 1A and 1B include: drive input and output assembly 100 ; rotational force multiplication assembly 200 ; vibratory force assembly 300 ; mode conversion assembly 400 ;

[0023] For example, refer to figure 1 , which shows an exploded perspective view of an embodiment of the present invention in the form of an apparatus 1 or offset drive linkage assembly 1 for delivering and increasing input from means for tightening or loosening threaded fasteners (not shown) ( not shown) torque. The device 1 includes: a driving force input assembly 100 ; a driving force output assembly 200 ; and a reaction force assembly 400 . The apparatus 1 also includes a drive ...

Abstract

An offset drive link assembly for transmission and multiplication of torque from a power tool for tightening or loosening a threaded fastener includes: a drive force input assembly; a drive force output assembly; and a reaction force assembly. Advantageously the offset drive link assembly: allows access to previously unreachable fasteners due to, for example protruding threads, limited clearances and obstructions; makes practical previously unusable devices driven either electrically, hydraulically, manually and / or pneumatically; makes feasible previously unusable advanced materials, such as, for example aircraft-grade aluminum; creates modular components, such as, for example hex-reducing and -increasing drive bushings, male to female drive adaptors, to meet bolting application characteristics; yields accurate and customizable torque multiplication; tames drive force and reaction force application; overcomes corrosion, thread and facial deformation; avoids bolt thread galling; nullifies side load; ensures balanced bolt load for symmetrical joint compression; simplifies link and tool use; minimizes risk of operator error; and maximizes bolting safety.
