Abstract
The utility model discloses a key components high strength driving hoist electric block reduction gear that the driving hoisting machinery used. Middle part under input shaft (1) is fixed in its sun gear (10), its outside and second planet wheel (8) meshing, second planet wheel (8) and second fixed ring gear (7) meshing, second planet axle (6) activity sets up in second planet wheel (8), and connect with planet carrier (9) that set up on input shaft (1), first planet axle (3) are gone up first planet wheel (4) of installation and are moved ring gear (2) meshing with first fixed ring gear (5) and output, and and planet carrier (9) are connected. Because the utility model discloses a planet kind of drive that combines together of planet transmission and the poor transmission of special few tooth, become moving axis line gear drive by dead axle line gear drive, become interior meshing by outer meshing, make more equiblibrium mass distribution of transmission stress, greatly improved life.
Description
Technical field
Model utility relates to the critical component high strength driving hoist electric wire hoist retarder that a kind of Hoisting Machinery of driving a vehicle uses.
Background technique
Driving hoist electric wire hoist traditional is at present the meshing transmission devices of dead axle line transmission three grades of deceleration external tooths, its shortcoming one is that stress is concentrated when carrying, very easily damage, two is that manufacturing process is complicated, need special tooling, too much, manufacture cost is high for jig and equipment, and increase energy consumption, reduce use power.
Model utility content
The utility model overcomes the drawback that former hoist electric wire hoist exists, and provides a kind of transfer force equiblibrium mass distribution, saves manufacture and maintenance cost, drastically increases the high strength driving hoist electric wire hoist retarder of application in working life.The technological scheme that the utility model is adopted for achieving the above object is: its sun gear 10 is fixed on input shaft 1 time middle part, its outside and the second planet wheel 8 engage, second planet wheel 8 and the second fixing ring gear 7 engage, second planet axis 6 is movably arranged in the second planet wheel 8, and be connected with the planet carrier 9 be arranged on input shaft 1, the first row star-wheel 4 that first planet axle 3 is installed and first is fixed ring gear 5 and is exported dynamic gear ring 2 and engages, and is connected with planet carrier 9.
Effect of the present utility model is: owing to have employed the Gear Planet Transmission mode that Gear Planet Transmission combines with special few teeth difference transmission, rotation axis gear transmission is become from the transmission of dead axle line gear, from outer meshing become interior meshing, thus make transfer force more equiblibrium mass distribution, drastically increase working life.Without the need to changing other part dimension, can support the use with legacy equipment, by change gear, the gear ring number of teeth and modulus, being applicable to the product of all size.And volume is little, lightweight, manufacturing process is simple, saves manufacture and maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, its sun gear 10 is fixed on input shaft 1 time middle part, its outside and the second planet wheel 8 engage, second planet wheel 8 and the second fixing ring gear 7 engage, second planet axis 6 is movably arranged in the second planet wheel 8, and be connected with the planet carrier 9 be arranged on input shaft 1, the first row star-wheel 4 that first planet axle 3 is installed and first is fixed ring gear 5 and is exported dynamic gear ring 2 and engages, and is connected with planet carrier 9.
As shown in Figure 1, the second described planet axis 6 and first planet axle 3 are arranged on an overall planet carrier 9 on different circumferential angle.
As shown in Figure 1, the described first fixing ring gear 5 is identical with dynamic gear ring 2 modulus of output, and is consistent with the first row star-wheel 4.
As shown in Figure 1, gear ring 2 is moved in described output should fix the several tooth of ring gear more than 5 or few several tooth than first.
Working principle of the present utility model is: input shaft 1 drives sun gear 10, reach two the second planet wheels 8, because the second planet wheel 8 fixes engaging of ring gear 7 with second, second planet wheel 8 pairs sun gear does planetary motion, drive two second planet axis 6 that planet carrier 9 is synchronized with the movement simultaneously, now planet carrier to the speed ratio of planet wheel be the number of teeth of 1+ fixing tooth 7 divided by the sun gear number of teeth, adjust depending on various needs.Second planet axis 6 and first planet axle 3 are arranged on an overall planet carrier 9 on different circumferential angle, first planet axle 3 in the running, the first row star-wheel 4 that its axle is installed is fixed ring gear 5 simultaneously and is exported dynamic gear ring 2 and engages with first, the several tooth of ring gear more than 5 or few several tooth should be fixed than first owing to exporting dynamic gear ring 2, when the first row star-wheel 4 public affairs circle, export the motion that dynamic gear ring 2 is exactly a week few turn or many turns of several teeth for the first fixing ring gear 5, i.e. few teeth difference transmission, drive connection is that the fixed gear ring number of teeth is divided by (the fixed gear ring number of teeth-dynamic gear ring number of teeth), the number of two gear ring number of teeth quantity, determine depending on velocity ratio size and output clockwise and anticlockwise, but two gear ring moduluses must be identical, and be consistent with the first row star-wheel 4, and adopt displacement profile of tooth.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
1. a high strength driving hoist electric wire hoist retarder, it is characterized in that sun gear (10) is fixed in the middle part of under input shaft (1), its outside and the second planet wheel (8) engagement, second planet wheel (8) and the second fixing ring gear (7) engagement, second planet axis (6) is movably arranged in the second planet wheel (8), and be connected with the planet carrier (9) be arranged on input shaft (1), the upper the first row star-wheel (4) installed of first planet axle (3) is fixed ring gear (5) with first and is exported dynamic gear ring (2) and engages, and be connected with planet carrier (9).
