Description
Technical field
It is especially a kind of to pump taking away for sled equipment for oil fracturing the utility model relates to shaft coupling transmission technical field
Close the Hooks coupling universal coupling of function.
Background technique
Due to oil fracturing pump injection pressure operation need to ensure operation continuously can not discontinuity, currently, oil fracturing pump sled is logical
Frequently with the arragement construction of two, a motor band pumps.Two pump operations simultaneously when normal work, if side is in an emergency,
When such as transmission shaft damage or other special circumstances, side transmission shaft can be made, which to disengage with power, makes pump stop working, and another pump
It still can individually continue operation.It not only can guarantee continuously going on smoothly for pump operation in this way, avoid generating immeasurable economic damage
It loses, and burst fortuitous event can be effectively prevent to lead to equipment damage and operating personnel's personal safety hidden danger.
In addition to this, it contacts or separates with friction plate by hydraulic drive spring there are also a kind of, to realize clutch function
Single-side flange formula shaft coupling, hydraulic when due to the shaft coupling working condition are constantly in state of pressure keeping, so shaft coupling temperature rise
It is higher, and there are problems that hydraulic leak.Meanwhile such shaft coupling angular deviation compensation rate and axial displacement compensation rate are all very
Small, when installation, need to check the concentricity of motor shaft and pump input shaft, it is necessary to assure within 0.7mm and strict control motor
The axially mounted distance of axis and fracturing pump.Since whole fracturing pumping equipment weighs tens tons, motor and pump are all heavier, this transmission
Axis mounting and adjusting is difficult.In use, transmission shaft can not flexibly respond fracturing pump axial float, and axial displacement compensation rate is small,
The problem of being easy to appear fracturing pump pinion shaft spline damage.
Summary of the invention

The hydraulic interface seat of the arrangement of clutch is fixed by screws in flange shaft, between hydraulic interface seat and flange shaft
Equipped with O-ring one；Slide is mounted on the left of flange spindle-type chamber, and the side of slide and hydraulic interface seated connection touch, slide and flange shaft
Between be equipped with sealing ring one, sealing ring two, sealing ring；Push rod is connected by nut two, gasket and slide, between push rod and slide
Equipped with O-ring two；Spring is installed on push rod, and limit sleeve and guide sleeve are mounted in the cavity wall of flange shaft, the side of spring
With another side contacts of slide, the other side of spring is withstood on the inner cavity step surface of flange shaft；Push plate seat is mounted on push rod, is led to
It crosses pin limit, is locking, the outer circle of the push plate on inside and outside diameter with arc surface is mounted on the groove between outer ring one and outer ring two
Interior, inner circle is mounted in the groove of push plate seat.
The raceway is round, ellipse or kidney-shaped.
The center of the steel ball one and raceway is set as at a distance from two inner face of gland away from L, two left side of retainer is set as
S, one left side of inner ring are set as M at a distance from push plate seat right side, and limit sleeve left side is set as D at a distance from slide inner face,
Coupler structure size meets S > L, M > L, D=L.
The hydraulic clutch device of the utility model is hydraulic by injecting into hydraulic interface seat when pump needs power to disconnect
Oil, oil pressure push slide compressed spring and to push push plate seat and push plate together with push rod, and push plate pushes outer ring one and outer ring two same
When move to right in the raceway for making steel ball one enter outer ring one, outer ring one and outer ring two move to right at a distance from controlled by limit sleeve.It needs
When pump works again, the spring of hydraulic oil unloading, compressive state drives the homings such as outer ring one, outer ring two, slide, steel ball one
Into in the axial channels of outer ring one, power is again coupled to.
The utility model compared with prior art, has the advantage that
1, shaft coupling installation is simple, is able to achieve biggish angle compensation and length compensation.
2, compared with former shaft coupling, can faster response fracturing pump axial float and generate length variation, grown in time
The case where spending compensating for variations, effectively avoiding fracturing pump pinion shaft spline damage.
3, the hydraulic clutch device of the shaft coupling is normally closed under working condition (normality), does not need oiling and keeps centainly
Oil pressure only keeps oil pressure, and the number for needing to be detached from the entire life cycle of pump in short-term when needing to disengage power
It is quite few.Therefore, it compared with former friction plate clutch formula shaft coupling, avoids the need for normality and keeps shaft coupling temperature rise caused by oil pressure
It is larger, the problem of hydraulic fluid leak.
4, it not only can guarantee continuously going on smoothly for pump operation, avoid generating immeasurable economic loss, and can have
Effect prevents burst fortuitous event from leading to equipment damage and personnel's personal safety hidden danger.
