Description
Technical field:
The utility model relates to the downhole tool that uses on a kind of oilfield, the eccentric coupling of particularly a kind of pressure-bearing type
Background technique:
When down-hole drive screw pump oil production system was worked, the rotor of screw pump was done eccentric motion, can produce several tons axial load simultaneously.The main mode that solves eccentric rotary and concentric rotating connection at present has cross Hooks coupling universal coupling and flexible shaft dual mode.But because structure is limit, when axial load was excessive, the application of the two was restricted, and can't work long-term effectively in the down-hole.
Technological scheme
The utility model purpose is to provide a kind of pressure-bearing type eccentric coupling, solved the connection problem between the eccentric rotary of the concentric rotation of motor output and screw pump rotor, and in transmitting torque, the epitrochanterian axial load that acts on that produces when screw pump is worked carries out the transition on the housing, avoids other parts to be subjected to the influence of axial load.
The utility model purpose is to realize like this, it is by input shaft (1), stop ring (2), tapered roller bearing (3), thrust bearing (4), inhalation valve (6), lip seal (7), guide pin bushing sealing (8), lower sleeve gasket (9), key (10), external toothing (11), steel ball pressure-bearing body (12), internal tooth casing (13), steel ball (14), retaining ring (15), retainer (16), output shaft (17), upper sleeve gasket (18), sealing slip ring (19), spring (20), pressure regulation retaining ring sealing (21) is formed, on input shaft (1), be socketed with stop ring (2) successively, tapered roller bearing (3), thrust bearing (4), housing (5), lip seal (7), guide pin bushing sealing (8), its bottom is embedded with key (10), and with external toothing (11), steel ball pressure-bearing body (12) connects, steel ball (14) is sitting in retaining ring (15), on the retainer (16), lower sleeve gasket (9) is socketed on the external toothing (11), and be connected with internal tooth casing (13), on retainer (16), be socketed with output shaft (17) successively, upper sleeve gasket (18), sealing slip ring (19), spring (20), pressure regulation retaining ring sealing (21), overcoat is housing (5), and inhalation valve (6) is arranged on it.
During work, input shaft is done dead axle and is rotated, output shaft keeps free state, do eccentric rotary, output shaft adopts gear type to be connected with input shaft, and the gear teeth are shaped as crowned teeth, has realized that the flexibility between output shaft and the input shaft connects, allow certain beat motion surplus, guaranteed that the dead axle rotation is connected with the reliable of eccentric rotary.Axial force on the output shaft is delivered to input shaft by steel ball, is delivered on the housing by the thrust bearing on the input shaft again, has avoided axial load to transmit downwards.Steel ball rolls on the pressure-bearing track body, when transmitting axial load, has guaranteed can not interfere phenomenon between output shaft and the input shaft.It is lubricated that inner multiple-sealed of device guaranteed that the lubricated chamber of lower bearing and steel ball, gear connect the cleaning of chamber.
The utility model is owing to adopted on input shaft, be socketed with stop ring successively, tapered roller bearing, thrust bearing, lip seal, the guide pin bushing sealing, its bottom is embedded with key, and and external toothing, steel ball pressure-bearing body connects, steel ball is sitting in retaining ring, on the retainer, lower sleeve gasket is socketed on the external toothing, and be connected with internal tooth casing, on retainer, be socketed with output shaft successively, upper sleeve gasket, the sealing slip ring, spring, the pressure regulation retaining ring sealing, can improve moment of torsion and axial load bearing capacity greatly, realize the synchronous transmission of moment of torsion and axial load, improve machinery driving efficiency, improve the application area and the reliability of down-hole drive screw pump oil production system, and can be applicable to down-hole helicoid hydraulic motor drilling well.It is reasonable in design, and is simple in structure, is well suited for field popularization application.
