The compact flexible connection structure is simple to install, small in installation space and convenient to maintain, reduces the maintenance intensity of workers, and prolongs the service life of the motor.
Description
Technical Field
The utility model belongs to the technical field of the oil-well rig slush pump hookup, concretely relates to directly drive flexible draw bail of slush pump compact drive.
Background
The low-speed large-torque direct drive motor for the slurry pump of the petroleum drilling machine eliminates a heavy transmission belt or a transmission chain part, avoids the adverse effects of complex structure, large rotational inertia, low efficiency, increased noise, leakage of lubricating oil, frequent maintenance and the like brought by a speed reducing mechanism, meets the working condition requirements of constant torque, constant power and the like, and is an ideal substitute for the traditional motor and speed changing mechanism. However, the direct-drive motor drives the slurry pump by adopting rigid connection modes such as a taper shaft sleeve and the like, so that the vibration of the slurry pump is increased during operation, the problems of damage or loose connection and the like of a bearing of the direct-drive motor are caused, the normal operation of the slurry pump is seriously influenced, and the drilling progress is further influenced.
Disclosure of Invention
The utility model aims at providing a directly drive flexible connection structure of slush pump compact drive solves the not enough of prior art, has guaranteed the normal operating of slush pump.
The utility model discloses a directly drive flexible draw bail of slush pump compact drive that realizes through following mode, including directly driving motor output shaft, slush pump transmission shaft, flexible coupling connecting plate, flexonics roller combination. The flexible connection roller combination comprises a mounting flange, a shaft sleeve, a flexible connection transmission shaft, a flexible roller and a protection plate, wherein the mounting flange is sleeved on one end of the flexible connection transmission shaft through the first flexible roller, the shaft sleeve is sleeved on the other end of the flexible connection transmission shaft through a second bearing, and two ends of the protection plate are respectively connected with the mounting flange and the shaft sleeve in a sliding sealing mode; the direct-drive motor output shaft is fixedly connected with the flexible connecting plate through the positioning spigot and the compression bolt, the compression bolt is reliably fastened, the torque of the motor is transmitted through static friction to drive the mud pump transmission shaft, the mounting flange is connected with the flexible connecting plate and transmits the torque through the cross key, and the shaft sleeve is connected with the mud pump transmission shaft through the flat key and transmits the torque.
The preferable combination of the flexible connecting plate and the flexible connecting roller is processed by alloy steel.
The beneficial effects of the utility model are that can steadily drive the slush pump operation, avoid the violent vibration of operation in-process, reduce the impact to the motor bearing and the slush pump body, and this compact flexible connection structure installation is simple, and installation space is little, and it is convenient to maintain, has reduced workman's maintenance, maintenance intensity, has prolonged the life-span of motor.
