Description
Technical field
The utility model relates to the gear transmission field, more specifically to a kind of labour saving machine.
Background technique
In the prior art, gear transmission can only be laborsaving, and its deficiency is; Energy utilization ratio is not high.
The model utility content
Technical problem to be solved in the utility model is to overcome existing gear transmission, and the shortcoming of deficiency that can only be laborsaving provides a kind of province merit device.
Technology solution of the present utility model is as follows:
A kind of province merit device, gear 1, gear 2, gear 3, the position in axle center in alignment.The shaft type activity chain is connected to gear 2, gear 3 on planet carrier 4.Gear 1 is meshed with gear 2: gear 2 and gear 3 angled being meshed.The rotating shaft of gear 2, gear 3 is fixedly connected on the planet carrier 4, and planet carrier 4 rotates around the axle of gear 1, and gear 1 usefulness bar 5 is fixed on the support 6.On gear 3, install mitre gears chain 7 additional, on the fixing rod 5 bearing is housed; Bearing outside diameter 8, internal diameter 9, the axle of internal diameter 9 distaffs 5 rotates.Universal truckle a, b and the corresponding truckle c with it of two mutual one-tenth angles are housed on the external diameter 8.The cogged that adds of internal diameter 9 is meshed with chain 7, and internal diameter 9 installs the gear 10 of amplification again additional.
Described gear 1 can be identical gear with gear 2, and the diameter of gear 3 is 2 times of gear 1, and gear 3 is less than or equal to 120 degree angles with 2 one-tenth of gears and is meshed.
The described gear 2 that rotates around gear 1 is one or more.
The novel outstanding effect of this reality is: no matter apply the load of much power on gear 10, planet carrier 4 suffered power all are in balance.The power of rotation planet carrier 4 only equals the frictional force between the gear.

Embodiment
See Fig. 1, a kind of province merit device, the shaft core position of gear 1, gear 2, gear 3 is in alignment, and the shaft type activity chain is connected to gear 2, gear 3 on planet carrier 4.Gear 1 is meshed with gear 2, and 3 one-tenth 120 degree of gear 2 and gear angle is meshed; The rotating shaft of gear 2, gear 3 is fixedly connected on the planet carrier 4.Planet carrier 4 rotates around the axle of gear 1.Gear 1 usefulness bar 5 is fixed on the support 6, installs mitre gears chain 7 on gear 3 additional, on the fixing rod 5 bearing is housed; Bearing outside diameter 8, internal diameter 9, the axle of internal diameter 9 distaffs 5 rotates.Universal truckle a, b and the corresponding truckle c with ab of two mutual one-tenth angles are housed on the bearing outside diameter 8.Internal diameter 9 adds cogged and gear 3 and installs chain 7 engagements additional, and the radius that internal diameter 9 adds cogged is slightly less than the radius of gear 3.Install the gear 10 of amplification on the internal diameter 9 again additional.Chain 7 by ab angle and internal diameter 9 install gear engagement additional, pass through corresponding pulley c again, the gear engagement that installs additional with gear 3 forms circulation again.
Working principle: see Fig. 2, when rotating planet carrier 4 with very little power f, planet carrier 4 rotates around the axle of gear 1.If when installing the mitre gears chain additional on gear 3 (end is fixed), when drawing gear 3, planet carrier 4 is motionless with very big power F (direction of power and axis parallel).Its reason is: the run-on point of planet carrier 4 is in the axle center of gear 1, and the axle center of gear 2, gear 3 is on planet carrier 4, and at this moment, planet carrier 4 suffered power are in balance.If tooth radius is r.F.4r＝2F.2r。The F of this formula can be an arbitrary value.That is to say: no matter apply great load force F on chain, it is all very little to rotate the required power of planet carrier 4.(here very for a short time is to have only the frictional force between gear and the resistance of air, and be as follows)
But chain is zero with respect to the displacement in the axle center of fixed gear 1, does not do work.
As long as the distance in the axle center of the axle center of gear 1 and gear 2 equals the distance in the axle center and gear 3 axle center of gear 2, planet carrier 4 suffered power just are in balance.
How just can make planet carrier 4 suffered power not only be in balance but also displacement is arranged?
The meeting Fig. 1, planet carrier be designed to 120 the degree angles, the radius of gear 3 increases to 2 times of gear 1 radius.When the engagement of 3 one-tenth 120 degree of gear 2 and gear angle, though the radius of gear 3 increases 2 times, the distance of shaft centers of gear 2 and gear 3 is from equaling the distance of gear 1 with gear 2 axle center.(right-angled triangle 30 degree pairing limits, angle equal half of hypotenuse). be that planet carrier 4 suffered power are in balance.
When the radius of gear 3 increases to the twice of gear 1, rotate counterclockwise planet carrier 4,3 of gears circle round the commentaries on classics half cycle and produce displacement.Chain 7 externally does work by pulley ab pulling gear 10.
No matter the load force F on the gear 10 is much, rotates planet carrier 4 with very little power f and can do work.
In application, be designed to a plurality of directions of energy conversion between the button of chain 7 and the button, make it the gear engagement that installs additional with internal diameter 9.Chain 7 equals the radius of gear 3 through the angle of a, b pulley to the distance of BEARING SHAFT, and because of the radius that tooth radius is slightly less than gear 3 that installs additional of internal diameter 9, chain 7 makes bearing outside diameter 8 suffered power be in balance by the angle of pulley a, b.
The effect of pulley a, b, c is: make bearing outside diameter 8 be in balance, chain 7 is subjected to force direction constant.
