Abstract
The invention relates to a gear transmission labor-saving accelerating device. The device comprises a sun gear 1, a planet gear 2, an outer gear ring 3, a central gear 4 and a transmission chain 5 of a planetary gear set, wherein the sun gear 1 is connected with the planet gear 2 through tooth surface contact to realize transfer of force and speed; the planet gear 2 is in contact with the outer gear ring 3 through the tooth surface contact; the force and the speed are transferred to the central gear 4 through the transmission chain 5. According to the transmission characteristic of the planet gear, the superposition of autorotation speed and revolution speed of the planet gear 2 is realized, so that the gear transmission efficiency is higher and the transmission ratio is higher. The labor-saving acceleration effect is fundamentally achieved.
Description
Technical field
The present invention relates to a kind of gear drive, particularly a kind of gear transmission Labor-saving accelerator.
Background technique
Existing gear drive is all that velocity ratio equals gear ratio and rotating ratio with face to realize the transmission of speed and moment of torsion.And, moment of torsion is larger between moment of torsion and rotating speed inversely, rotating speed is less, and moment of torsion is less, and rotating speed is larger.Depend merely on the size regulating moment of torsion and rotating speed, fundamentally can not solve problem that is laborsaving and that accelerate.
The content of invention
Object of the present invention is just to provide a kind of gear transmission Labor-saving accelerator, and laborsaving and acceleration can combine by effectively, make gear-driven efficiency higher.
The object of the present invention is achieved like this: a kind of gear transmission Labor-saving accelerator, comprises the sun gear 1 of planetary gear set, planet wheel 2, ring gear 3, central gear 4, drive chain 5.Sun gear 1 is connected with planet wheel 2 by face, and planet wheel 2 is connected with external toothing 3 by face, and planet wheel 2 is connected with central gear 4 by drive chain 5.
Owing to adopting said structure, gear transmission is organically combined by face and chain transmission, and make gear-driven efficiency higher, velocity ratio is larger.Fundamentally reach the effect of laborsaving acceleration.
Accompanying drawing explanation
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is structural representation of the present invention.
The double accompanying drawing that makes an abstract of Fig. 1.
Fig. 2 is force analysis figure of the present invention.
In figure: 1, sun gear, 2, planet wheel, 3, ring gear, 4, central gear, 5, drive chain.
Embodiment
As shown in Figure 1, a kind of gear transmission Labor-saving accelerator, comprises sun gear 1, planet wheel 2, ring gear 3, central gear 4, drive chain 5.Sun gear 1 is wanted to connect by face and planet wheel 2, and planet wheel 2 is connected with ring gear 3 by face, and planet wheel 2 is connected with central gear 4 by drive chain 5.
If the number of teeth of gear is N, rotating speed is W, and planet wheel 2 revolution speed is V, so, draws according to planetary drive characteristic:

According to the above derivation of equation, work as N
4< N
2time, velocity ratio is greater than gear ratio, reaches the requirement of acceleration; Work as N
4=N
2time, velocity ratio equals gear ratio; Work as N
4> N
2time, velocity ratio is less than gear ratio.
Force analysis:
As shown in Figure 2, a kind of gear transmission Labor-saving accelerator, comprises sun gear 1, planet wheel 2, ring gear 3, central gear 4, drive chain 5.Sun gear 1 and planet wheel 2 are wanted to connect, and planet wheel 2 is connected with ring gear 3, and planet wheel 2 is connected with central gear 4 by drive chain 5.
If be F stressed, wheel radius is R, draws formula:
F
2＝F
1×R
1/2R

4＝F
2×R
2/R
4＝F1×R

As sun gear 1 input power F
1time, planet wheel 2 does circumference fortune by ring gear 3, therefore produces inertial centrifugal phenomenon, inertial force F
usedact on drive chain 5, be decomposed into along drive chain 5 and the power Fa of planetary pinion 2 tangent direction and the power Fb perpendicular to drive chain 5 direction, due to Fa and F
2direction is identical, according to above formula:
F
2＝F
4×R
4/R
2-Fa

2/R
1×(F
2-Fa)
When the angle a > 90 ° of the tangent line of drive chain 5 and planet wheel 2 is followed in the direction of inertial force Fa, Fa is just, direction is identical with the direction of the tangent line of planet wheel 2 with drive chain 5, F
2be added with Fa, reach labour-saving effect; As a=90 °, Fa is zero; As a < 90 °, Fa is negative, and the direction of the tangent line of direction and drive chain 5 and planet wheel 2 is contrary.
