Abstract
The utility model relates to a hydraulic motor used for driving a underwater screw anchor, comprising a hydraulic motor crankshaft, a hydraulic motor shaft end cover, and a back end seal ring fixed between the crankshaft and the shaft end cover, characterized in that an additional O-ring can be fixed at the forepart between the crank and the shaft end cover and also an O-ring can be used as a substitution of the original J-ring functioning as the seal ring on the back end. The advantages are simple structure and good waterproof performance. The manner of adopting O-ring solves the problem of sealing function failure of the original seal ring caused by the pressure out of the chamber (water pressure) bigger than the pressure inside of the chamber after the hydraulic motor diving but before starting up. The seal ring can be used in three agents-oil, water and gas under conditions of operating pressure P is less than 35MPa, rubbing speed V is less than 6m/s and operating temperature t=-40Celsius system -+40 Celsius system.
Description
(1) technical field
The utility model relates to a kind of oil hydraulic motor, especially relates to a kind of driving oil hydraulic motor of screw anchor under water.
(2) background technique
At present, screw anchor is the land utensil, screw anchor be placed under water as the anchor of sitting basic skill or training's journey thing under water, its driving arrangement is that oil hydraulic motor must possess anti-water condition, but existing oil hydraulic motor uses " J " shape seal ring, and water tightness is poor, can't use under water.
(3) summary of the invention
Technical problem to be solved in the utility model provides a kind of driving oil hydraulic motor of screw anchor under water, and simple in structure, water tightness is good, is suitable for using under water.
For addressing the above problem, the technical solution of the utility model is: this drives the oil hydraulic motor of screw anchor under water, comprise the back-end sealing circle between oil hydraulic motor bent axle, oil hydraulic motor hubcap and oil hydraulic motor bent axle and the oil hydraulic motor hubcap, it is characterized in that " O " shape seal ring can be set in the front portion between oil hydraulic motor bent axle and the oil hydraulic motor hubcap again, also can adopt " O " shape seal ring original to replace " J " shape seal ring the back-end sealing circle.
Have and " O " shape seal ring corresponding grooves in oil hydraulic motor hubcap front inner wall.
Have and " O " shape seal ring corresponding grooves at oil hydraulic motor hubcap rear end inwall.
The utility model has the advantages that simple in structure, good water-proof effect.Adopt " O " shape seal ring solved oil hydraulic motor after diving and before starting because of the problem of its chamber pressure outside (hydraulic pressure) greater than the former seal ring seal failure that cavity pressure caused.The sealing circle can adapt to three kinds of working mediums of Oil, Water, Gas, and all can use under working pressure P＜35Mpa, friction velocity V＜6m/s, operating temperature t=-40 ℃ of-+40 ℃ of conditions.

Fig. 2 is Figure 1A portion enlarged diagram;
Fig. 3 drives under water that the oil hydraulic motor embodiment's 2 of screw anchor master looks schematic representation;
Fig. 4 is Fig. 3 B portion enlarged diagram.
(5) embodiment
Embodiment 1: as shown in Figure 1 and Figure 2, oil hydraulic motor bent axle 1, oil hydraulic motor hubcap 3 and back-end sealing circle 4, back-end sealing circle 4 are " J " shape rubber oil seal with reinforce, and this oil sealing only can play the one-way sealing effect.Front portion between oil hydraulic motor bent axle 1 and oil hydraulic motor hubcap 3 increases " O " shape seal ring 2, and " O " shape seal ring 2 has good two way sealed effect, remedies the defective of " J " shape seal ring.Make oil hydraulic motor have water proofing property.Oil hydraulic motor hubcap 3 front inner wall have and seal ring 2 corresponding grooves 6.
Embodiment 2: as shown in Figure 3, Figure 4, oil hydraulic motor bent axle 1, oil hydraulic motor hubcap 3 and back-end sealing circle 4, seal ring 4 usefulness " O " shape seal ring 5 has replaced former " J " shape seal ring, makes oil hydraulic motor have water proofing property.Oil hydraulic motor hubcap 3 rear end inwalls have and seal ring 5 corresponding grooves 7.
Claims (3)
1. one kind drives the oil hydraulic motor of screw anchor under water, comprise the back-end sealing circle (4) between oil hydraulic motor bent axle (1), oil hydraulic motor hubcap (3) and oil hydraulic motor bent axle (1) and the oil hydraulic motor hubcap (3), it is characterized in that it is " O " shape seal ring (5) that front portion between oil hydraulic motor bent axle (1) and oil hydraulic motor hubcap (3) also has " O " shape seal ring (2) or back-end sealing circle (4).
2. driving according to claim 1 is the oil hydraulic motor of screw anchor under water, and it is characterized in that has and " O " shape seal ring (2) corresponding grooves (6) in oil hydraulic motor hubcap (3) front inner wall.
3. driving according to claim 1 is the oil hydraulic motor of screw anchor under water, and it is characterized in that has and " O " shape seal ring (5) corresponding grooves (7) at oil hydraulic motor hubcap (3) rear end inwall.
