Abstract
The torque wrench with quick release gear set is a system having a rotary actuator drive unit, which is attachable to a planetary drive gear set by a quick-release cylindrical adapter and collar so as to provide quick interchangeability of gear sets without the use of tools. The rotary actuator actuates the planetary gear set by means of a drive shaft connection through the quick-release cylindrical adaptor to engage a corresponding input gear drive shaft. The rotary actuator may have a pistol grip handle that rotates 360° to provide a user with an ergonomically friendly tool. The planetary gear set contains axial thrust bearings between each planet carrier to reduce friction and increase stability. The planet carriers are made of single piece construction to provide increased gear set durability. Precision radial bearings keep the planetary carriers and annulus concentric.
