Abstract
The utility model relates to a composite planetary reducer, which mainly includes a box body, a cylinder gear planetary transmission reducing mechanism consisting of an input shaft solar wheel and a planetary wheel, and a few teeth difference planetary gar transmission reducing mechanism consisting of a large gear and an internal gear. The large gear obtains the power by a crankshaft and ensures the two reducing mechanisms are densely combined in the internal chamber of the box body; the slow self-rotation speed of the large gear is transmitted to an output shaft made or connected into a whole with the left planetary frame by the crankshaft, in order to output the power. The utility model has the advantages of large transmission ratio range, high transmission efficiency, strong bearing capability and good rigidity, etc.
Description
The utility model relates to a kind of speed reducer, it mainly is the coaxial line type compound planetary speed reducer big for a kind of gear range, that transmission efficiency is high, bearing capacity is strong, can be widely used in industry fields such as metallurgical mine, petrochemical industry, lifting transportation, building machinery, grain and oil machinery, light textile printing, military project national defence, automatic control line, robot, be specially adapted to the transmission of power under large speed ratio, the high pulling torque operating mode.
The present general involute cylindrical gear Gear Planet Transmission speed reducer that adopts, involute planetary gear gear transmission speed reducer, the cycloid pinwheel planetary gear transmission system speed reducer, their single-stage step-down ratio is all less relatively, realize bigger velocity ratio, just must adopt the speed reducer of two-stage parallel connection or plural parallel stage, thereby comparatively speaking, volume is just big, weight is just heavy, complex structure, efficient is on the low side, single staged transmission ratio is little, especially wherein the structure of power output precision is owing to be subjected to the restriction of objective condition, be difficult to avoid weakness such as the poor rigidity vibration is big, thereby limited bearing capacity, the performance of overload capacity.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of to have a gear range big and provide, transmission efficiency height, the compound planetary speed reducer of the coaxial line type list casing that bearing capacity is strong.
The purpose of this utility model is achieved through the following technical solutions.This compound planetary speed reducer, the cylindrical gears Gear Planet Transmission reducing gear that mainly comprises casing, constitutes by input shaft sun gear and planet wheel, the small teeth number difference planet gear transmission speed reducer structure of forming by gearwheel and internal gear, gearwheel obtains power by bent axle, and two reducing gears are combined in the inner chamber of a casing compactly, gearwheel rotation rotating speed is at a slow speed passed to the output shaft outputting power of making or unifying with left planet carrier by bent axle.
The purpose of this utility model can also be further perfect by the following technical programs.Described bent axle is a pair of or a plurality of uniform, is equipped with two gearwheels, utilizes the effect of bent axle to make gearwheel produce the alternately sliding and swaying of mutual deviation 180 degree; Have the through hole that misplaces with crankshaft hole on the gearwheel, the through hole passageway that the suspension column of left planet carrier and right planet carrier passes gearwheel is tightened to integral body, forms the cage case structure.Gearwheel and internal gear can replace forming the cycloidal-pin wheel engagement driving with cycloid wheel and pin wheel housing respectively, and bent axle can replace with whole two eccentric rotary arm bearings.
The utility model advantage is: 1) two kinds of reducing gears organically combine, and produce compound decelerating effect, have enlarged gear range effectively; 2) adopt the box planet carrier of cage, replaced the cantilever type power output mechanism in general planetary speed reducer, few tooth difference speed reducer, the cycloid speed reducer, strengthened the integral rigidity of dirivig member in the casing effectively, make transmission part good rigidly, running steadily, system vibration is few, dynamic performance is good, bearing capacity and overload capacity extra-heavy; 3) to be installed in a cabinets cavity, compact structure, volume little, in light weight for two kinds of reducing gears; 4) under the equal speed ratio condition, the transmission efficiency height; 5) the deceleration system component of same specification, speed ratio, replaceable different casing and product design is designed to horizontal, vertical, wall-hanging and can be made into the motor direct connection.
Fig. 1 is that master of the present utility model looks schematic representation.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.This compound planetary speed reducer, the cylindrical gears Gear Planet Transmission reducing gear that comprises casing 6, constitutes by input shaft sun gear 1 and planet wheel 2, the small teeth number difference planet gear transmission speed reducer structure of forming by gearwheel 4 and internal gear 5, gearwheel 4 obtains power by bent axle 3, and double reduction mechanism is combined in the inner chamber of a casing 6 compactly, gearwheel 4 rotation rotating speed is at a slow speed passed to output shaft 9 outputting powers of making or unifying with left planet carrier 7 by bent axle 3.Bent axle 3 adopts a pair of or a plurality of uniform, is equipped with two gearwheels 4, utilizes the effect of bent axle 3 to make gearwheel 4 produce the alternately sliding and swaying that mutual deviation 180 is spent, to reach power dividing, stable transmission purpose.Have the through hole that misplaces with crankshaft hole on the gearwheel, the through hole passageway that the suspension column of left planet carrier 7 and right planet carrier 8 passes gearwheel 4 is tightened to integral body, forms the cage case structure.
