Abstract
The utility model provides an improved harmonic transmission anchor capstan. The casing of the harmonic transmission anchor capstan is arranged on a combined capstan of an anchor-chain sprocket and a mooring capstan, the casing of the harmonic transmission anchor capstan is arranged in the inner cavity of the assembly part of the anchor-chain sprocket and the mooring capstan. A harmonic drive master driver, a wave generator, a flexible gear, a circular spline, etc., are all standard components. An electric motor drags the assembly part of the anchor-chain sprocket and the mooring capstan by an output shaft of the electric motor through the harmonic transmission, which realizes the functions of deploying and retracting anchor chain and mooring cable. The utility model has the advantages of obviously reduced size and weight and improved reliability, and the utility model can satisfy the special requirements of ultra-lightweight boats.
Description
The utility model relates to a kind of improved anchor capstan, and particularly a kind of cable wheel and warping barrel inner chamber are provided with the anchor capstan of harmonic drive.Be applicable to middle-size and small-size ships and light boats.
Existing anchor capstan peculiar to vessel mostly is to drive cable wheel and gipsy capstan by electrical motor through worm type of reduction gearing, and its size is big, quality is big, driving efficiency is low, difficulty aboard ship is installed.For overcoming these shortcomings, the cycloidal-pin wheel retarder higher with driving efficiency replaces worm type of reduction gearing, but it is little to produce effects.Further developing of technology, cycloidal-pin wheel retarder master rotor is arranged on cable wheel and warping barrel inner chamber, the anchor capstan characteristics of this structure are, quality and size reduce, improved capstan winch mounting condition aboard ship, but its quality and size still can not satisfy some boats and ships should have microlight-type to anchor capstan requirement.The built-in anchor capstan structure of existing harmonic drive master rotor is to be driven by DC machine, is furnished with baroque overriding clutch, whole drive unit is provided with a large amount of antifriction-bearing boxs, complex structure not only, relative size and quality are also big, difficulty is installed by mechanism, safeguards inconvenience, can not make full use of the advantage of harmonic drive.
The purpose of this utility model is to provide a kind of size and quality little, simple in structure, easy to maintenance, reliable operation, the improved harmonic drive anchor capstan that the life-span is long.
The purpose of this utility model is achieved in that the shell of harmonic drive is arranged on the inner chamber of cable wheel and warping barrel, and constitute the support of anchor capstan, support is fixed by bolts on the mounting of hull, the cable wheel of anchor capstan and heaving pile tube with sliding supported condition on the shell of harmonic drive.The interior axis hole assembling of the output shaft of electrical motor and spectrum ripple transmission input shaft, with the key transmission, the wave producer of installing standard, flexbile gear and firm wheel on the input shaft, wave producer engages with flexbile gear, flexbile gear lower end external toothing and the internally toothed annulus engagement on the wheel just, just wheel to be being bolted on the support, and the upper end flange of flexbile gear is connected with flange on the harmonic wave transmission output shaft, constitute the drive shaft of anchor capstan, output shaft is connected with the warping barrel assembly set with cable wheel with key.The input shaft of direct motor drive harmonic drive during work through wave producer, flexbile gear and output shaft, drives cable wheel and warping barrel, realizes the function of anchor capstan folding and unfolding anchor chain or heaving pile cable.
The utility model adopts standard harmonic transmission master rotor owing to overriding clutch no longer being set, having reduced antifriction-bearing box quantity, has reduced size and quality, and simplified structure improves and safeguards, improves functional reliability and increases the life-span.
Concrete structure of the present utility model is described in further detail by following examples and accompanying drawing thereof.
Fig. 1 is the longitudinal section of a kind of structure of the utility model.
With reference to Fig. 1, the shell 1 of harmonic drive constitutes the support of anchor capstan, support is fixed by bolts on the mounting of hull, shell 1 is arranged on the cable wheel 4 of anchor capstan and the inner chamber of warping barrel 6, cable wheel 4 is bearing on the shell 1 through plain bearing 3, and warping barrel 6 is bearing on the shell 1 through plain bearing 5.Cable wheel 4 and warping barrel 6 usefulness bolt tightenings link into an integrated entity, and a drg 2 is established in the lower end of cable wheel 4.The output shaft 12 of electrical motor 13 cooperates with the input shaft 9 of harmonic drive, and with key connection transmission, the flexbile gear 8 of the wave producer 10 of installing standard, standard and Bo Fa device 10 engage on the input shaft 9, internally toothed annulus engagement on the external toothing of flexbile gear 8 lower ends and the firm wheel 11 of standard, just wheel 11 is fixed by bolts on the support 1, the upper end flange of flexbile gear 8 is connected with flange on the harmonic wave transmission output shaft 7, output shaft 7 constitutes the drive shaft of anchor capstan, output shaft 7 is connected with warping barrel 6 assembly sets with cable wheel 4 with key, and output shaft 7 lower ends are bearing in the endoporus of input shaft 9.
During anchor capstan work, electrical motor 13 drags wave producer 10 through transmission shaft 12 and 9, wave producer 10 rotates and can drive flexbile gear 8, through flexbile gear 8 and the tooth engagement of wheel 11 just, realize the feature of harmonic drive, flexbile gear 8 drags the assembly set of heaving pile circle tube 6 and sprocket wheel 4 through axle 7, thereby realizes the function of anchor capstan folding and unfolding anchor chain or heaving pile cable.
Claims (1)
1, one by support 1, drg 2, supporting 3, cable wheel 4, warping barrel 6, the anchor capstan that electrical motor 13 is formed, it is characterized in that the shell of harmonic drive is arranged on the inner chamber of cable wheel 4 and warping barrel 6, and constitute the support 1 of anchor capstan, support 1 is fixed by bolts on the mounting of hull, cable wheel 4 and warping barrel 6 bolt togethers, and be bearing in plain bearing 3 and 5 respectively, the interior axis hole assembling of the output shaft 12 of electrical motor 13 and harmonic drive input shaft 9 is with the key transmission, the wave producer 10 of installing standard on the input shaft 9, wave producer 10 engages with the flexbile gear 8 of standard, internally toothed annulus engagement on the external toothing of flexbile gear 8 lower ends and the firm wheel 11 of standard, just wheel 11 is fixed by bolts on the support 1, flange on the upper end flange of flexbile gear 8 and the harmonic wave transmission output shaft 7 connects and composes the drive shaft into anchor capstan, and output shaft 7 is connected with warping barrel 6 assembly sets with cable wheel 4 with key.
