Z375 Drilling Rig Components Rotary Table API 7K Dia. Of Opening
37.5 Inch
Rotary Table Product Information:
Rotary table is important part to drive and hold the drill string.
Rotary Table Technical Features
■The casing is cast steel and steel plate welding structure, the
basement is steel casting, it is welded with steel plate after
coarsely machining, and finish machining after integral annealing
for stress elimination.
■The transmission gear is the mid-hard tooth face arc cusp gear,
the intensity is high, the transmission is steady, the transmission
torque is big, the life is long.
■The input shaft is alloy forging by quench hardening and
tempering, has good mechanical property, fits for big torsional
moment operation. Chain wheel and flange can be equipped on the
shaft end. It meets the requirement of all transmission modes.
■Master bushing is made of alloy steel, and quenched and tempered,
it has high rigidity and reliable performance.
