Design Features

 

Rectangular Housing and Cover

Housing and cover are both rectangular. This makes it easier to position rig flooring whether the rotary top is flush with the floor or higher.

 

Unitized Gear Table Assembly

The table bearing is utilized with the gear table and gear. Thus, highly accurate bearing adjustment can be made before the assembly is installed in the housing. The gear and table assembly is balanced and mounted on a double-row ball thrust bearing. Design of this bearing assures that upper and lower ball tracks are exactly parallel and concentric.

 

Cartridge-type pinion shaft assembly

The pinion shaft and pinion bearings are enclosed in a cylindrical cartridge which inserts in to the main housing. The pinion is shrunk on the inner end of the pinion shaft. The shaft has a tapered extension at the outer end to accept a sprocket for chain drive or a coupling hub for shaft drive.

 

Selective Direct Table Locks

Two independently operated ratcheting lock pawls are arranged to engage slots in the rim of the table assembly. Via the lock pawls, the gear table can be locked in a single direction or both directions. Lock pawls are grease-lubricated.

 

Oil-lubricated Pinion, Gear and Bearing

Pinion and gear, pinion shaft bearings and gear table bearings are all cascade-lubricated from a large, central oil reservoir. Oil is added and the oil level checked at one easily accessible location.

 

Effective Mud and Oil Sealing

At the top of the gear table enclosure, a double tongue-and-groove labyrinth between gear and housing helps prevent loss of oil and entrance of mud. At the bottom of the gear table, a lip stops oil loss and a slinger helps prevent mud entrance. In the pinion shaft housing, a dual seal effectively keeps oil in and mud out.
