Abstract
The invention discloses a gear drive winch without an independent support of a drum shaft. The gear drive winch comprises a base, a motor is installed on the base, and the two ends of the motor are correspondingly connected with a left reduction gearbox and a right reduction gearbox in a transmission mode through couplers respectively. The left reduction gearbox and the right reduction gearbox are correspondingly connected with a left ball cage shaft coupling assembly and a right ball cage shaft coupling assembly respectively in a transmission mode. The two ends of the left ball cage shaft coupling assembly and the two ends of the right ball cage shaft coupling assembly are connected with a drum body assembly in a transmission mode. A drum shaft assembly is installed in the drum body assembly. The two ends of the drum shaft assembly are connected into the left ball cage shaft coupling assembly and the right ball cage shaft coupling assembly through a set of roller bearings in a sleeved mode respectively. In comparison with the prior art, independent wallboard-type or bearing-pedestal-type supports are removed, the ball cage shaft coupling assemblies are adopted for transmitting torque, therefore, drum-type gear couplers are removed, and the overall length of the winch is reduced.
Description
Technical field
The invention belongs to the oil-well rig equipment technical field, relate to a kind of drum shaft without independent support gear transmission winch.
Background technology
At present, oil-well rig gear transmission winch drum shaft often adopts axis structure, bearing seat type or wall board type to support, and adopts above-mentioned two kinds of supporting way to have the following disadvantages:
1) drum shaft adopts bearing seat or wall board type to support, and bearing seat supports or wallboard needs whole processing, has increased the processing and manufacturing cost; 2) drum shaft adopts bearing seat or wall board type to support, and the weight of bearing seat and wall is heavier, has lengthened winch length, increases the winch traffic cost; 3) drum shaft adopts bearing seat or wall board type to support, and drum shaft and reduction gearbox output shaft need to increase the connecting devices such as drum-type gear coupling, increase manufacturing cost, have also lengthened the winch overall length simultaneously; .
Summary of the invention
The purpose of this invention is to provide a kind of drum shaft without independent support gear transmission winch, solved the unreasonable structure existed in the prior art, cause the problem that overall dimensions is bigger than normal, weight is heavier.
The technical solution adopted in the present invention is, a kind of drum shaft is without independent support gear transmission winch, comprise base, motor is installed on base, the motor two ends are respectively by a coupler and left drop-gear box, right drop-gear box correspondence is in transmission connection, left drop-gear box, right drop-gear box respectively with left ball cage shaft coupling assembly, right ball cage shaft coupling assembly correspondence is in transmission connection, left ball cage shaft coupling assembly and right ball cage shaft coupling assembly are in transmission connection from two ends and barrel assembly, the drum shaft assembly is installed in the barrel assembly, drum shaft assembly two ends are socketed in left ball cage shaft coupling assembly by one group of coro bearng respectively, among right ball cage shaft coupling assembly.
Drum shaft of the present invention is without independent support gear transmission winch, and its characteristics also are:
Coro bearng adopts self-aligning roller bearing.
Motor adopts two, and two motors are in transmission connection by a coupler and left drop-gear box, right drop-gear box respectively.
The invention has the beneficial effects as follows, employing configures left and right ball cage shaft coupling assembly, self-aligning roller bearing as main support on left and right reduction gearbox output shaft, with bolts between left and right ball cage shaft coupling assembly and barrel, because ball cage shaft coupling assembly allows certain angular deviation, in the out-of-alignment situation of left and right reduction gearbox output shaft certain limit, can guarantee the automatic centering of barrel assembly in installation; Transmitting torque completes by ball cage shaft coupling assembly, easy for installation, reliable operation.
The present invention compared with prior art, has cancelled independent wall board type or bearing seat type and has supported, and adopts ball cage shaft coupling assembly transmitting torque, has cancelled drum-type gear coupling, has shortened the winch entire length.
