Description
Technical field
The present invention relates to a kind of screw lift, particularly relate to a kind of self-lubricating worm and gear screw lift.
Background technology
Along with the development that marine resources development utilizes, the demand of various extra large construction equipment is growing, therefore researchs and develops the mechanical drive being applicable to underwater environment and brings into schedule gradually.Worm and gear screw lift is as a kind of important mechanical drive, and generally use on the ground at present, being applied in underwater environment needs strict water-proff packing.But the pressure that dynamic sealing device can bear is very limited, existing technology cannot ensure worm and gear screw lift reliable operation in high pressure underwater environment, thus limits its degree of depth applied in ocean, hinders the step that deep-sea exploration advances.As can be seen here, a kind of research and development being applicable to the worm and gear screw lift of underwater environment are current extremely important and exigences.
Summary of the invention
The object of the invention is to the defect overcoming prior art, and a kind of self-lubricating worm and gear screw lift is provided, have simply compact, easy for installation, non-maintaining, transmission accuracy is high, and load is large, be applicable to the long-term continuous high speed of environment under water runs, and is also applicable to the advantage of very damp ground environment.
Technical matters solved by the invention realizes by the following technical solutions:
The technical scheme realizing above-mentioned purpose is:
A kind of self-lubricating worm and gear screw lift of the present invention, comprises a casing, a worm gear, laterally runs through a worm screw of described casing and longitudinally run through a screw mandrel of described casing; Described worm screw is rotatably connected with described casing respectively by a self-lubricating plain bearing with the two ends of described screw mandrel; Described worm gear is sheathed to be fixed on described screw mandrel, and the external tooth engaged transmission of the external tooth of described worm gear and described worm screw.
Further improvement of the present invention is, also comprises a sleeve, described jacket casing be located at described worm screw one end one described on self-lubricating free bearing, and this self-lubricating free bearing is fixed on described casing by described sleeve.
Further improvement of the present invention is, described sleeve one end forms flange, and described sleeve is fixed on described casing by being arranged in the screw being formed at described flange screw.
Further improvement of the present invention is, described casing, described worm gear, described worm screw, described screw mandrel, described self-lubricating plain bearing and described sleeve adopt waterproof material.
Further improvement of the present invention is, described worm screw is rotatably connected with described casing respectively by a self-lubricating plain bearing with the two ends of described screw mandrel.
The present invention is owing to have employed above technical scheme, and making it have following beneficial effect is:
The employing of self-lubricating plain bearing makes elevator can run for a long time in water.Sleeve is for installing the self-lubricating plain bearing of worm screw one end.The needs of the setting of sleeve mainly mounting process, the radial dimension of self-lubricating plain bearing is very little, its mounting hole is much less than worm screw external diameter, therefore needs to open the installation of auxiliary hole for worm screw in casing one end, on auxiliary hole, then arrange the sleeve for installing self-lubricating plain bearing.The engagement configuration of worm and worm wheel achieves the transmission of elevator.Described casing, described worm gear, described worm screw, described screw mandrel and described sleeve adopt waterproof material, make this device can environmental work under water for a long time, prevent water environment on the impact of each parts, extend the service life of elevator.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Refer to Fig. 1-Fig. 4, a kind of self-lubricating worm and gear screw lift of the present invention, comprise casing 1, worm gear 2, laterally run through a worm screw 3 of casing and longitudinal screw mandrel 4 running through casing; Worm screw 3 is rotatably connected with casing 1 respectively by a self-lubricating plain bearing 5 with the two ends of screw mandrel 4; Worm gear 2 is sheathed to be fixed on screw mandrel 4, and the external tooth engaged transmission of the external tooth of worm gear 2 and worm screw 3.Self-lubricating plain bearing 5 can bear sizable radial and axial load.The plain bearing 5 of self-lubricating comprises bearing shell, turns over all over forms such as cover, thrust washer and ball bowls, and is not limited thereto.Existing elevator uses antifriction-bearing box, and the present invention uses the elevator that makes of self-lubricating plain bearing 5 can run for a long time in water.
Also comprise a sleeve 6, sleeve 6 is sheathed on a self-lubricating free bearing 5 of worm screw 3 one end, and this self-lubricating free bearing 5 is fixed on casing by sleeve 6.Sleeve 6 one end forms flange, and sleeve is fixed on casing 1 by being arranged in the screw being formed at flange screw.
Casing 1, worm gear 2, worm screw 3, screw mandrel 4, self-lubricating free bearing 5 and sleeve 6 adopt waterproof material.Make this device can environmental work under water for a long time, prevent water environment on the impact of each parts, extend the service life of elevator.
The present invention substitutes conventional rolling bearing by using self-lubricating plain bearing 5; Casing 1, worm gear 2, worm screw 3, screw mandrel 4, self-lubricating free bearing 5 and sleeve 6 adopt waterproof material, and preferred all parts materials are waterproof material; Casing 1 structure is open type, eliminates traditional shaft seal; Realize at the present invention's reliable operation in high pressure underwater environment.In addition, owing to present invention employs self-lubricating free bearing 5 and each parts employing waterproof material, the present invention in use without the need to adding lubricating oil and shaft seal, thus makes the present invention non-maintaining.
