BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A shows a perspective view of a modular winch. FIG. IB shows a cross-sectional view of the modular winch of FIG. 1 A. FIG. 1C shows a view of a pinion and gear ring of the modular winch of FIG. 1A. FIG. 2 shows a perspective view of a modular winch with a section cut out for viewing purposes.
DETAILED DESCRIPTION FIG. la shows a perspective view of modular winch 10, Fig. lb shows a cross-sectional view of modular winch 10, and Fig. lc shows a view of gear ring 12 with pinions 14 of modular winch 10. Drum 16 can support a cable, rope, tube, chain or other flexible device which can wind around drum 16.
Modular winch 10 includes drum 16 with shaft 18, winch supports 20 and drive system 22. Drive system 22 includes gear ring 12, frame 24 (with front face 25, openings 26 and mounts 27) and drive units 28. Each drive unit 28 includes motor 29, gearbox 30, housing 32 and pinion 14.
Drum 16 rotatably connects to winch supports 20 on either side through shaft 18. Drum also connects to gear ring 12 to rotate with gear ring 12.
Drive system 22 connects to drum 16 through gear ring 12, winch support 20 and through shaft 18. Frame 24 is connected to shaft 18 through a bearing which allows drum 16 to rotate without rotating frame 24. Frame 24 is also connected to support 20 through bolts or other connection means. Pinions 14 are connected to frame 24 on one end at mounts 27, which allow pinions 14 to be rotated. On the other end, pinions 14 are connected to gearbox 30, which is connected to motor 29. Housing 32 is connected to motor 29, frame 24 and winch support 20, through bolted or other connection means. Drive unit 28 could also include a brake to selectively engage the pinion.
Drive system 22 rotates drum 16 to cause a cable on drum 16 to wind or unwind. Drive system 22 causes drum to rotate through pinions 14 and gear ring 12. In each drive unit 28, motor 29 drives gearbox 30 which in turn drives pinion 14. Pinions 14 then collectively drive gear ring 12, which rotates drum 16 to wind or unwind the cable or other device which it is supporting.
Gear structure of drive system 22 is a closed gear structure. The connection between pinions 14 and the teeth of gear ring 12 are enclosed by frame 24 and the outer surface of gear ring 12. Additionally, gearbox 30 is surrounded by housing 32 to further enclose gear structure of drive system 22.
Modular winch 10 is driven by drive system 22 with a plurality of drive units 28 with a closed gear structure connected to gear ring 12 with internal toothing. This allows winch 10 to be driven using a plurality of smaller drive units 28, allowing for a wide range of driving force without taking up a lot of space. Additionally, the closed gear structure protects the drive system 22 from exposure to environmental factors and conditions which can damage the gear system.
In past winches which could handle large tensile forces, the drive system typically needed a large, expensive and complicated gearbox. The motor size required to drive such a system would normally use a large amount of space. The large, complicated gear system was typically an open gear system built up on the side of the winch, connecting to a gear ring 12 with external toothing. This open gear system was susceptible to environmental conditions and factors, which could damage the gear system and the overall drive system.
Modular winch 10 is powered by drive system 22 which is robust and can provide large forces without the need for a lot of space by using a plurality of smaller drive units 28 with a closed gear system for driving winch 10 through gear ring 12. Depending on the force required, a different number of drive units 28 can be connected to frame 24. The closed gear system formed by using gear ring 12 with internal teething, pinions 14 and frame 24 protect the drive system 22 from damage due to environmental factors, for example sand entering and damaging gear system. Additionally, this modular system allows for easy repairs, as a drive unit 28 can be easily exchanged for a new drive unit 28 if not working. FIG. 2 shows a perspective view of a modular winch 10 with a section cut out for viewing purposes. As above, modular winch 10 includes drum 16 with shaft 18, winch supports 20 and drive system 22 (with gear ring 12, frame 24 with front face 25 and openings 26, mounts 27, drive units 28 and cover plates 36). In this embodiment, gearbox 30 and pinions 14 of drive units 28 are shown schematically, with motor 29 and housing 32 not shown.
In the embodiment shown in Fig. 2, frame 24 has a front face 25 with six openings 26 for receiving drive units 28 (only five openings are shown due to the section cut out for viewing purposes). Winch 10 of Fig. 2 only requires the power of three drive units 28, which are mounted to frame 24. The openings 26 which do not receive drive units 28 are covered by cover plates 36 to ensure that the gear system of drive system 22 remains closed and protected.
In summary, drive system 22 is robust and able to provide a large amount of force for driving winch 10 without taking up a large amount of space through the use of a plurality of smaller drive units 28 with an enclosed gear system. The use of gear ring 12 with internal teeth to connect to pinions 14 and the shape and connections of frame 24 provide the drive system 22 with an internal gear structure, which protects drive system 22 and can lead to a longer life for both drive system 22 and winch 10. Additionally, the use of a plurality of drive units 28 can result in easier repairs, as a drive unit can simply be taken out and exchanged if in need of repair or replacement.
While frame 24 has been shown with openings 26 and mounts 27 for connecting six drive units 28, more or fewer openings 26 and mounts 27 could be used depending on system and force requirement. Additionally, the shape, structure and connections of frame 24 could vary depending on drive system requirements.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
