API 175 Rotary table and accessories for drilling rig
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole.
The pinion and gear are made of alloy steel
The master bushing for rotary table is made from a steel casting
Pin transmission type is suitable for API standard square or hexagonal kelly roller bushing
Effective lubrication and reliable seals are provide by design.
Most rotary tables are chain driven. These chains resemble very large bicycle chains. The chains require constant oiling to prevent burning and seizing.
Rotary Locks - Virtually all rotary tables are equipped with a rotary lock. Engaging the lock can either prevent the rotary from turning in one particular direction, or from turning at all. This is commonly used by crews in lieu of using a second pair of tongs to makeup or break out pipe.
The rotary bushings are located at the center of the rotary table. These can generally be removed in two separate pieces to facilitate large items, i.e. drill bits, to pass through the rotary table. The large gap in the center of the rotary bushings is referred to as the "bowl" due to its appearance. The bowl is where the slips are set to hold up the drill string during connections and pipe trips as well as the point the drill string passes through the floor into the wellbore. The rotary bushings connect to the kelly bushings to actually induce the spin required for drilling
