Abstract

A power tong assembly has a transmission box having a plurality of speeds. A gear train completely encircles a rotary gear by including idler gears, fluid lines and actuating mechanisms within a tong door, which itself can be remotely operated. Cam roller assemblies can be inversely mounted into cage plates and a support race can be mounted into an opening, thereby eliminating the need to cut a groove in a rotary gear. Filler blocks can be inserted adjacent to gears to catch and redirect slung grease from gears back to said gears, while dampening noise and reducing the misuse of grease, thereby increasing effectiveness of lubrication. A make and break actuator assembly can be housed on the power tong body such that it is completely covered from external damage except when momentarily activated. A symmetric rotary gear, rotary gear inserts, cam shoe inserts and over-travel cam stops are provided.
