The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model will be further described:
Wherein, each sequence number representative is:
1-hydraulic motor, 2-screw, 3-packing ring, 4-brake, 5-axle sleeve, 6-Qian great Gai, 7-bolt, 8-packing ring, 9-little gear ring, 10-external gear assembly, 11-spacer flanger, 12-sun gear assembly, 13-pin, 14-bolt, 15-bolt, 16-nut, 17-bull gear, 18-rear support flange, 19-planet carrier component, 20-axle sleeve, 21-bearing, 22-axle sleeve, 23-bearing, 24-seal cover, 25-screw, 26-oil sealing, 27-rear support, 28-shaft end ring, 29-gear output shaft, 30-back-up ring, 31-end cap.
Wherein, power is by hydraulic motor 1 input, it be fixedly to connect mutually by bolt and axle sleeve 5 and front large lid 6, the bent axle in the output shaft of hydraulic motor 1 and external gear assembly 10 passes through spline coupling.Planetary Gear Transmission is compared and is had the advantages such as supporting capacity is high, volume is little, efficiency is high, lightweight, gearratio is large, noise is low, reliability is high, the life-span is long with the parallel-axes gears transmission.Therefore adopt the planetary gear speed-reduction transmission, according to design, adopt the two-stage Gear Planet Transmission, the resultant gear ratio of Gear Planet Transmission is 300-500
.the monodentate lifting force can reach: normal lifting monodentate lifting force 80-200 ton, prefabricating load monodentate power 150-230 ton, the sudden and violent load monodentate of wind resistance power 200-260 ton, rising or falling speed 0-4 ft/min.The lifting gear gross efficiency is up to more than 80%, and this is rare in big speed ratio and top load transmission.External force is inputted through 10 outputs of external gear assembly by bent axle, and it belongs to small Tooth Number Difference Planetary Transmission, comprises two of external gears, one of planet carrier, external gear is linked together by bearing pin and planet carrier, and by two eccentric rotary of bent axle, power passes to the secondary planet transmission through external gear and planet carrier.The secondary planet wheel is arranged on planet carrier component 19, secondary solar gear assembly 12 passes through splined with external gear assembly 10, the secondary planet wheel meshes with bull gear 17 again, the center line of secondary solar gear assembly 12 and secondary planet wheel rotation and the center line of bull gear 17 are concentric---both common axis, the secondary planet wheel has two kinds of motion rotations and revolution (around self axis and common axis) like this, because the secondary planet wheel is 3, so increased simultaneously stressed gear logarithm, increased substantially bearing capacity, structure is more compact, volume obviously reduces.Planet carrier component 19 by spline as output form, gear output shaft 29 ends connect with spline mutually with planet carrier component 19, gear output shaft 29 other ends are gears that the number of teeth is large modulus, large pressure angle, and this lifting gear is arranged on platform main structure backgear output shaft 29 and is meshed to realize lift platform with tooth bar, puts purposes such as receiving spud leg.
This lifting gear all gears except gear output shaft, internal gear adopt carburizing and quenching, roll flute processing technology, internal gear adopts high rigidity quenched and tempered steel essence gear shaping technique, therefore transmission accuracy is very high, and gross efficiency still can reach more than 80% in big speed ratio 300-500 situation.
In the utility model, change the progression of planetary gear reducing mechanism and the connecting mode changed between adjacent planetary gear reducing mechanism and can form a plurality of embodiment, be common variation of the present utility model and protection domain, at this, do not describe in detail one by one.
