Description
Technical field
The utility model belongs to oil-well rig slush pump connection technique field, and in particular to drives to a kind of straight slush pump that drives
Flexible coupling mechanism.
Background technique
Oil-well rig slush pump directly drives motor with low-speed big and has eliminated bulky driving belt or driving chain portion
Part, avoiding deceleration mechanism bring, structure is complicated, rotary inertia is big, efficiency reduces, noise increase, oil leakage, maintenance
Adverse effect is frequently waited, meets the working condition requirements such as permanent torque, invariable power, is the ideal substitute that conventional motors add gear.
But the straight variable-frequency motor driving slush pump that drives generally uses the rigid attachments mode such as tapered hub, adds vibration when mud pump operation
Greatly, it causes direct driving motor bearing to damage or couple the problems such as loosening, seriously affects slush pump normal operation.
Summary of the invention
The utility model aim provides one kind straight drive slush pump driving flexible coupling mechanism, the deficiency to solve the above problems,
Guarantee the normal operation of slush pump.
The utility model is achieved in the following ways a kind of straight drive slush pump flexible coupling mechanism, flexible connected connection
Plate is fixedly connected by positioning spigot with hold-down bolt with direct driving motor output shaft, and flexible coupling mechanism axle sleeve passes through flat key and mud
Stock pump propeller shaft couplings are fixedly connected, and flexible cage group is equipped between flexible connected connecting plate and flexible coupling mechanism axle sleeve
It closes.The left end of the flexible cage combination is mounted with to connect with flexible connected connecting plate, its right end and flexible coupling mechanism
Axle sleeve installation connection combines to be equipped in the cavity between direct driving motor output shaft positioned at flexible cage and does not tear machine oiling device open,
The machine oiling device of not tearing open is mounted on flexible cage combination above and communicates therewith.
The flexible connected connecting plate is equipped with oiling through-hole, does not tear the pump nozzle lower half sealing peace of machine oiling device open
In oiling through-hole, and the upper portion of pump nozzle is in the outside of flexible connected connecting plate.
The combination of flexible cage by flexible connected connecting plate, flexible coupling mechanism axle sleeve respectively with motor shaft, mud pump shaft
Connection, flexible drive mud pump work.
The beneficial effects of the utility model can smooth drive mud pump operation, avoid the high vibration in operational process,
The impact to motor bearings and the slush pump pump housing is reduced, and the installation of this flexible coupling mechanism is simple, it is easy to maintain, reduce work
The maintenance, repair intensity of people, extends the service life of motor.
Detailed description of the invention
