Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of speed reduction gearing and engaging and disengaging gear.
Detailed description of the invention
Embodiment of the present utility model is illustrated below in conjunction with Fig. 1 and Fig. 2.
A kind of electric capstan, comprise support, motor 1 is provided with in the head side of support, reel 2 is provided with at the middle part of support, speed reduction gearing 3 is provided with at the rear side of frame, described speed reduction gearing 3 adopts the three-stage planetary gear drive mechanism be made up of primary planet transmission component 31, secondary planet transmission component 32, third-level planetary transmission component 33, third-level planetary transmission component 33 drives reel by output gear 21, described three-stage planetary gear drive mechanism is installed in drop-gear box 34, and the rear portion of described drop-gear box is provided with engaging and disengaging gear 4.
As shown in Figure 2, described engaging and disengaging gear 4 comprises clutch gear 41, described clutch gear 41 is installed on clutch shaft 43, brake spring 42 is provided with between described clutch gear and drop-gear box rear box wall, the tail end of clutch shaft passes drop-gear box and installs a clutch lever 44, is connected between clutch lever with clutch shaft by flathead screw.The gear ring of one secondary planet transmission component is identical, adopts a secondary gear ring 311, and clutch gear coordinate with secondary gear ring 311 clutch in a secondary planet transmission component reach electric capstan from, conjunction state.
Capstan winch is all arranged on comparatively in narrow space usually, therefore more little lighter better.Planetary wheel can reach this requirement, can produce larger reduction ratio again, successful simultaneously, and the speed reduction gearing therefore in the utility model adopts three-stage planetary gear drive mechanism, and tertiary gear is with being contained in a drop-gear box, and afterbody is with clutch gear mechanism.
Clutch works: by rotation clutch handle, pull clutch shaft, have three boss above clutch shaft, clutch shaft pulls clutch gear ring (gear ring end face having three slopes) again, make itself and a secondary gear ring without fixation, can rotate along with the rotation of gear.
The utility model improves clutch mode, adopt clutch gear depart from a secondary gear ring reach capstan winch from, close state, such design, planetary wheeling assembly can be made to reach integraty, stable drive, can not occur from, close not smooth phenomenon, therefore improve stability and the reliability of engaging and disengaging gear.
Three-stage planetary gear drive mechanism is direct-connected by hexagonal drive link and motor output shaft, and the other end of hexagonal drive link supports with bearing 37 feels relieved.In three-stage planetary gear drive mechanism, the external diameter of a secondary planet transmission component is identical, and the external diameter of a secondary planet transmission component is less than the external diameter of third-level planetary transmission component.
Existing capstan winch noise in operational process is comparatively large, therefore along with technological advance, just requires that hook noise reduces further, from design angle, the planetary wheeling assembly of existing capstan winch is suspension structure, not centering, so swing must be had in operational process, cause noise.Therefore, the other end bearing of the drive link out from motor one end or similar structure are felt relieved by the present embodiment, just greatly can reduce noise.
Meanwhile, one skilled in the art will appreciate that I and II planetary transmission assembly is higher than the rotating speed of three grades, but the external diameter of conventional winches one two three grades is equally large, therefore main noise source is in front secondary.Therefore, in the present embodiment, reduced by the external diameter of a secondary planet transmission component, the linear velocity of its external diameter is correspondingly just little, make it be less than the external diameter of third-level planetary transmission component, and then produced noise also can be little.
Therefore by above two technical measures, the capstan winch of design has obvious effect in reduction noise.
When motor output shaft passes to first order planetary wheeling assembly by transmission shaft, cause the waste of power of high speed level.Therefore in the present embodiment, transmission shaft adopts hexagonal drive link (with motor side by hexagonal cross-sectional respective outer side edges).Primary planet pinion is direct-connected by hexagonal drive link and motor side, decreases the loss of transmission shaft, after slowing down again by transmission shaft driven to the second stage, third-level planetary wheel assembly, process facts have proved, substantially increases the machinery driving efficiency of complete machine.
At present, a new trend of capstan winch industry is exactly that client requires that capstan winch water in the situation of drenching with rain can not enter in motor and deceleration box.Therefore take in from hermetically-sealed construction, specifically: packing seal 12 is installed between motor and support, O RunddichtringO 36 is provided with between drop-gear box 34 casing and drop-gear box cover plate 35, sealing lip 23 is provided with between drop-gear box cover plate 35 and reel side 22, the seal ring 24 that cross section is L-type is provided with between drop-gear box cover plate 35 and bobbin trunk, in addition, multi-sealing structure 45 is provided with between clutch shaft 43 and Gearbox.Because the present embodiment have employed above-mentioned seal approach, the waterproof problem of capstan winch is solved, thus make the performance of whole capstan winch, service life improves greatly, improves cost performance.
