A kind of driving reel with planetary mechanism
The utility model relates to a kind of driving reel, relates in particular to a kind of driving reel with planetary mechanism, belongs to the winch field.
Winch is divided into two kinds of manual hoist and electric winchs.Be main with electric winch now, it mainly comprises electrical motor, plunging joint, drg, reductor and reel, is installed in jointly on the frame; Reductor is installed in reel outside one side, drives reel and rotates, and its weight is bigger; Overall volume is also big; Drive part weight is brought very big pressure to reel outside reel two fulcrums, stressed irrational distribution concerning reel.
Summary of the invention
Because the defective that existing procucts exist; This use is novel to be that a kind of driving reel with planetary mechanism will be provided; A side is provided with planetary mechanism in its reel, with all or part of threading reel of reductor the inside, reduces the purpose of the volume and weight of whole drive part.
To achieve these goals, the technical solution of the utility model is: a kind of driving reel with planetary mechanism, and it mainly comprises: input shaft, output shaft, bearing and cylinder; It is characterized in that: it also comprises planetary mechanism; Bearing is connected with reel, and input shaft is positioned at bearing inside and is connected with planetary mechanism, and planetary mechanism is fixed in reel inside; Output shaft is positioned at the rear portion of reel, and output shaft is provided with second bearing; Said planetary mechanism comprises packing ring, internal tooth casing, clutch shaft bearing, planet wheel spindle, satellite gear, needle bearing, internally toothed annulus, sun wheel and pinion carrier, and input shaft is connected with sun wheel through internal tooth casing, and the sun wheel two ends are provided with packing ring; Sun wheel is meshed with satellite gear, and satellite gear is around the planet wheel spindle rotation, and the planet wheel spindle both sides are provided with needle bearing; The needle bearing outside is provided with internally toothed annulus; Be provided with the clutch shaft bearing bearing between internally toothed annulus and the cylinder, sun wheel is connected with pinion carrier, pinion carrier be provided with male splines; Reel is provided with female splines, and the male splines on the pinion carrier matches with female splines on the reel.
The principle of work of the utility model is:
Rotary power is imported by input shaft, is delivered to sun wheel by internal tooth casing, and sun wheel and satellite gear engagement to planet wheel spindle, are delivered to pinion carrier with transmission of power again, through the spline pair engagement, transmission of power to reel, is realized the reel takeoff output.
The advantage of the utility model is: a side is used easy planetary mechanism in reel; With all or part of threading reel of reductor the inside; Reduced the volume and weight of whole drive part; Dwindle 1/3 approximately, in two fulcrums of center of gravity shift-in reel with whole reel, make the stressed of reel be tending towards reasonable.
