Abstract
The utility model discloses one and directly drive slurry pump driving flexible coupling mechanism, comprise overcoat, inner sleeve, cover plate, it is characterized in that, inner sleeve is connected with mud pump shaft by flat key, overcoat by positioning spigot and hold-down bolt with directly drive variable-frequency electric arbor and coordinate and connect, overcoat inner ring is arc internal spline, and inner sleeve outer ring is arc external splines, inside and outside spline fitted; Cover plate protection is installed in inner sleeve and overcoat front end, and and inner sleeve, fills lubricant grease between overcoat.The utility model knot can run by smooth drive slurry pump, avoids the high vibration in running, reduces the impact to motor bearings and the slurry pump pump housing.Install simple, easy to maintenance, reduce the maintenance, repair intensity of workman, avoid the high vibration in running, reduce the impact to motor bearings and the slurry pump pump housing, extend the life-span of motor.
Description
Technical field
The utility model relates to oil-well rig mud pump equipment field, is specifically related to one and directly drives slurry pump driving flexible coupling mechanism.
Background technique
Oil-well rig slurry pump low-speed big directly drives motor and has eliminated heavy drivign belt or drive chain parts, the adverse effect such as avoid that complex structure that reducing gear brings, rotary inertia are large, efficiency reduction, noise increase, oil leakage, maintenance are frequent, meeting the working condition requirements such as permanent moment of torsion, invariable power, is the ideal substitute that conventional motors adds gear.But directly driving variable-frequency motor drives slurry pump generally to adopt the rigid joint modes such as tapered hub, and when making slurry pump run, vibration strengthens, and causes direct driving motor bearing to damage or connects problems such as loosening, having a strong impact on slurry pump and normally run.
Model utility content
For solving the problem, this novel one that provides directly drives slurry pump driving flexible coupling mechanism, can run by smooth drive slurry pump, avoids the high vibration in running, reduce the impact to motor bearings and the slurry pump pump housing.
For realizing above object, by the following technical solutions:
One is directly driven slurry pump and is driven flexible coupling mechanism, comprise overcoat, inner sleeve, cover plate, it is characterized in that, inner sleeve is connected with mud pump shaft by flat key, overcoat by positioning spigot and hold-down bolt with directly drive variable-frequency electric arbor and coordinate and connect, overcoat inner ring is arc internal spline, and inner sleeve outer ring is arc external splines, inside and outside spline fitted; Cover plate protection is installed in inner sleeve and overcoat front end, and and inner sleeve, fills lubricant grease between overcoat.
The utility model benefit effect: install simple, easy to maintenance, reduce the maintenance, repair intensity of workman, avoid the high vibration in running, reduce the impact to motor bearings and the slurry pump pump housing, extend the life-span of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
As shown in the figure: 1, directly drive variable-frequency electric arbor; 2, overcoat; 3, inner sleeve; 4, cover plate; 5, mud pump shaft.
Embodiment
Embodiment
As shown in Figure 1, inner sleeve (3) is connected with mud pump shaft (5) by flat key, overcoat (2) by positioning spigot and hold-down bolt with directly drive variable-frequency electric arbor (1) and coordinate and connect,, overcoat (2) inner ring is arc internal spline, and inner sleeve (3) outer ring is arc external splines, inside and outside spline fitted, inner sleeve (3) and overcoat (2) are by inside and outside spline fitted, and inner sleeve (3) and overcoat (2) front end are installed cover plate (4) and protected, and and inner sleeve (3), overcoat fill lubricant grease between (2).Inner sleeve (3) and overcoat (2) adopt high strength alloy steel to process, and its arc splined surfaces high frequency hardening ensures spline intensity.Arc spline fitted can compensate the axis and radial error that direct driving motor connects with slurry pump, reaches the requirement of soft drive.Cover plate reliable protection flexible coupling mechanism, and in fill lubricant grease, ensure proper lubrication.
