Abstract
The utility model discloses a star gear speeding-up box which is formed by a power input shaft, a sun gear, three planet gears, a planet frame, an annular gear, a machine casing and a power output shaft. The power output shaft is installed on the machine casing through a bearing, the sun gear is positioned in the machine casing and arranged at the end of the power output shaft, the three planet gears are evenly distributed at the periphery of the sun gear and respectively meshed with the sun gear, the annular gear is arranged in the machine casing, positioned at the peripheries of the three planet gears and meshed with the three planet gears, the planet frame is arranged at the end of the power input shaft and arranged at the periphery of the sun gear, and the three planet gears are arranged on the planet frame. By means of a planet transmission work mode, the three planet gears of the same structure are evenly distributed around a central wheel, inertia force between the planet gear and a rotary arm can be balanced, and the star gear speeding-up box has the advantages of being stable in motion and strong in impact resistance.
Description
Technical field
The utility model relates to a kind of booster engine, specifically is a kind of spider gear speedup box.
Background technique
Booster engine is a kind of autonomous device of being made up of the gear transmission, worm drive or gear one worm drive that are enclosed in the rigid body, and main type has gear increaser, worm screw booster engine, gear one worm screw booster engine etc.The cylindrical gears speed increaser has single-stage, secondary, more than the secondary, uses very extensive.The cone gear speed increaser is used for the occasion that input shaft and output shaft position become to intersect.The worm screw speed increaser is mainly used in velocity ratio greater than 10 occasion.All there are shortcomings such as delivery efficiency is low, structure is not too compact, and bearing capacity is big inadequately in above-mentioned booster engine.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of spider gear speedup box with stable work in work, strong shock resistance.
To achieve these goals, the technical solution adopted in the utility model is:
The spider gear speedup box, it is by power input shaft, sun gear, three planetary pinions, planet carrier, ring gear, casing and pto constitute, described pto by Bearing Installation on casing, sun gear is located in the casing and is installed in the end of pto, three planetary pinions are evenly distributed on the peripheral of sun gear and are meshed with sun gear respectively, ring gear is located in the casing and is positioned at peripheral and three planetary pinions of three planetary pinions and is meshed, planet carrier is located at the end of power input shaft and is positioned at the periphery of sun gear, and three planetary pinions are located on the planet carrier.
Described casing is a cylinder-like structure, and two ends are provided with end cap.
The bottom of described casing is provided with air hole.
The beneficial effects of the utility model: owing to adopt the mode of operation of above-mentioned star transmission, three planetary pinions that structure is identical have been adopted, be distributed in equably central gear around, thereby the mutual balance of the inertial force that can make planetary pinion and pivoted arm, have compact structure, quality is little, volume is little, motion is steady, the characteristics that anti-impact force is strong.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of planetary pinion shown in Figure 1 and sun gear.
Among the figure: 1, power input shaft; 2, planet carrier; 3, planetary pinion; 4, ring gear; 5, casing; 6, sun gear; 7, pto; 8, air hole.
Embodiment
As shown in Figure 1, 2, the spider gear speedup box, it is to be made of power input shaft 1, sun gear 6, three planetary pinions 3, planet carrier 2, ring gear 4, casing 5 and ptos 7, described casing 5 is a cylinder-like structure, two ends are provided with end cap, and the bottom of described casing is provided with air hole 8.Described pto 7 by Bearing Installation on casing 5, sun gear 6 is located in the casing 5 and is installed in the end of pto 7, three planetary pinions 3 are evenly distributed on the peripheral of sun gear 6 and are meshed with sun gear 6 respectively, ring gear 4 is located at the interior of casing 5 and is positioned at peripheral and three planetary pinions 3 of three planetary pinions 3 and is meshed, planet carrier 2 is located at the end of power input shaft 1 and is positioned at the periphery of sun gear 6, and three planetary pinions 3 are located on the planet carrier 2.
Working principle: the planetary pinion transmission is that the working principle according to epicyclic train realizes mechanical speedup.During work, power input shaft 1 drives planet carrier 3 and rotates, and planet carrier 3 drives planetary pinion 3 and rotates along ring gear, and through the transmission of one-level speedup, planetary pinion 3 drives sun gear 2 and rotates, and is driven pto 7 by the sun gear 2 of speedup and rotates.Because the planetary pinion transmission has power dividing and each central gear constitutes the transmission of coaxial line formula and reasonably uses internal gear pair, so its structure is very compact; Several planetary pinions are shared load jointly owing to distributing equably around central gear, thereby make that the load that each gear bore is less, and allow these gears to adopt less modulus; Because the symmetry properties of planetary pinion drive mechanism, promptly it has the planetary pinion of several well-balanced distributions, the feasible mutual balance of reaction force energy that acts in central gear and the rotary arm bearing, thus help reaching the effect that improves transmission efficiency.
