Dynamic device is all made up of driver sleeve, gluing core print seat, upper gland etc., and driver sleeve uses screw thread with gluing core print seat and gluing core cup
Connect and fixed by upper gland, be easy to that the situation that upper gland unclamps with gluing core cup screw thread, gluing occurs in use
Core print seat and gluing core cup sealing are poor.
The content of the invention
The utility model proposes a kind of ocean drilling next-generation drive for improving actuator seal.
What the technical solution of the utility model was realized in：
A kind of marine drilling next-generation drive, including actuator body, hexagon socket head cap screw, "O"-ring, gluing core cup and glue
Core, actuator body are connected with gluing core cup using the hexagon socket head cap screw of high intensity, adopted between actuator body and gluing core cup
Being sealed with the "O"-ring of twice fluorubber material, actuator body is connected by screw bolts glue core, wherein, the driver
Some tooth form grooves are provided with body, and corresponding toothed projections structure is provided with the gluing core cup.
Preferably, the "O"-ring is fastened in the tooth form groove.
Preferably, the "O"-ring quantity is corresponding with the quantity of the tooth form groove.
Preferably, the end of the tooth form groove and toothed projections does not offset.
Preferably, the "O"-ring is interference fitted with the tooth form groove and toothed projections respectively.
Above-mentioned technical proposal is employed, the beneficial effects of the utility model are：In the utility model, in the driver sheet
The tooth form groove being engaged and toothed projections are set on body and gluing core cup, fix both more firm, while institute
State "O"-ring to be fastened in the tooth form groove, and offseted with toothed projections, increase the sealing of driver.

Driver；Fig. 3 is the enlarged drawing in A portions in Fig. 2, is referred to shown in Fig. 1 to Fig. 3.Show that a kind of preferably marine drilling is new
Driver, including actuator body 1, hexagon socket head cap screw 2, "O"-ring 3, gluing core cup 4 and glue core 5, actuator body 1 use
The hexagon socket head cap screw 2 of high intensity is connected with gluing core cup 4, and twice fluorubber is used between actuator body 1 and gluing core cup 4
The "O"-ring 3 of material is sealed, and actuator body 1 is connected by screw bolts glue core 5, is monolithically fabricated the new driving of marine drilling
Device.
Wherein, be provided with some tooth form grooves 11 in the actuator body 1, and be provided with the gluing core cup 4 with
Its corresponding toothed projections structure 41, and then cause both preferably engagings, fixation is more firm.
More specifically, the quantity of "O"-ring 3 is corresponding with the quantity of the tooth form groove 11, and is fastened on the tooth
Sealed in connected in star 11 and then to the actuator body 1 and gluing core cup 4.
The end of wherein described tooth form groove 11 and toothed projections 41 does not offset, and then provides sky for the setting of "O"-ring 3
Between, the "O"-ring 3 is interference fitted with the tooth form groove 11 and toothed projections 41 respectively.
In the utility model, set in the actuator body 1 and gluing core cup 4 the tooth form groove 11 that is engaged with
And toothed projections 41, fix both more firm, while the "O"-ring 3 is fastened in the tooth form groove 11, and with
Toothed projections 41 offset, and increase the sealing of driver.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
