Example systems, apparatuses and methods are disclosed for gear reduction. An example system comprises a second gear configured to be disposed in mesh with a first gear coupled to an input shaft. The system further comprises a carrier housing configured to be fixably disposed within the second gear. The system further comprises a third gear configured to be disposed within the carrier housing; a fourth gear configured to be disposed in mesh with the third gear, wherein the third gear is further configured to rotate about the fourth gear; an anti-backlash gear coupled to the fourth gear and configured to be disposed in mesh with the third gear; and a fifth gear configured to be disposed in mesh with the third gear. The second gear, the fourth gear, the anti-backlash gear, and the fifth gear are configured to be disposed along a common axis of rotation.

Embodiments generally relate to assembly and methods for precisely rigging a linear variable differential transformer (LVDT). For example, the probe rod assembly of a dual tandem LVDT may comprise two moveable cores, a probe fitting, and a probe rod. Generally, the first moveable core may be configured to achieve electrical zero with its respective transformer. Without adjusting the position of the probe rod with respect to the one or more coils of wire, the second moveable core may be configured to achieve electrical zero with its respective transformer. This may ensure that both moveable cores simultaneously achieve electrical zero in the null position. Typically, the probe fitting may be configured to fit at a first end of the probe rod projecting outward from the outer housing. The disclosed assembly and methods may be used to precisely rig dual tandem LVDTs, single channel LVDTs, and dual parallel LVDTs.
