发明名称 APPARATUS AND METHOD FOR CONNECTING TUBULARS OF A WELLSITE
摘要 A rotational driver for driving a connector through adjacent tubulars is provided. The adjacent tubulars are positionable in a wellbore of a wellsite for passing fluid therethrough. The rotational driver includes a gearbox housing positionable about the connector, a socket carried by the gearbox housing to receivingly engage the connector, and a plurality of gears driven by at least one motor. The gears are operatively connectable to the socket to transfer torque from the motor thereto, and have interlocking teeth defining a plurality of contacts therebetween whereby load on the gears is distributable therebetween.
