Abstract
A kind of actuating unit, it is characterized in that power output shaft support and support are adapted to are fixed on support base respectively, flywheel is arranged in power output shaft support by power output shaft, rack frame is by four groove pulley adaptations on support, flywheel is connected by guide rod with rack frame adaptation, power input shaft support two ends are fixed on support, driving gear is arranged in power input shaft support by power input shaft, the rack on rack frame both sides is engaged with driving gear respectively, the present invention can be in the case where keeping input speed and output speed identical precondition, improve the effect of driving force 50%.
Description
Technical field
The present invention relates to a kind of mechanical actuating unit.
Technical background
The operation principle of speed changer is it is well known that speed changer multiple of driving force of its output speed with being increased while driving force is increased is inversely proportional.
The content of the invention
It is an object of the invention to provide a kind of actuating unit, the present apparatus can keep power input shaft and power output shaft speed under the same conditions, increase driving force.
What the present invention was realized in：Power output shaft is supported and support is adapted to is fixed on support base respectively, and flywheel is arranged in power output shaft support by power output shaft.Rack frame is adapted to rack-mount by four groove pulleys, flywheel is connected by guide rod with rack frame adaptation, power input shaft support two ends are fixed on support, and driving gear is arranged in power input shaft support by power input shaft, and the rack on rack frame both sides is engaged with driving gear respectively.Two toothed rack symmetrical balances on the rack frame are set, and the number of teeth of unilateral rack can not be more than the half of driving gear itself number of teeth on the rack frame, and the driving gear need only use the number of teeth of half.
When driving force is driven rack by the power input shaft of the present invention by driving gear, rack frame will left and right back and forth do horizontal stroke motion, while rack frame promotes flywheel turns by guide rod, driving force spread out of by power output shaft again.Because driving gear only has the number of teeth of half, when driving gear is from when going around, driving gear will be promoted by the infeed stroke for driving the rack of rack frame both sides to do once back and forth respectively, so as to which rack frame just drives one turn of flywheel turns by guide rod, so power input shaft is identical with the revolution of power output shaft constant.Because the perimeter dimension of driving gear reference circle is approximately 3 times of itself reference diameter size more.So the half of the perimeter dimension of driving gear reference circle is up to 1.5 times of itself reference diameter size.So rack frame do back and forth infeed stroke motion apart from size will be 1.5 times of driving gear reference diameter size.When namely guide rod promotes flywheel turns back and forth, the stress point of flywheel to itself center of circle is 1.5 times of driving gear radius size cun apart from size.So as to which the present invention can be in the case where keeping input speed and output speed identical precondition, with the effect for improving driving force 50%.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the operation principle schematic diagram of the present invention.
Fig. 2 is the vertical section structural map of groove pulley.
1. support base in figure, the support of 2. power output shafts, 3. flywheels, 4. power output shafts, 5. guide rods, 6. supports, the support of 7. power input shafts, 8. driving gears, 9. groove pulleys, 10. rack frames, 11. power input shafts.
Embodiment
In Fig. 1, power output shaft support 2 and support 6 are adapted to are fixed on support base 1 respectively, and flywheel 3 is arranged in power output shaft support 2 by power output shaft 4.Rack frame 10 is installed on the frame 6 by four adaptations of groove pulley 9, flywheel 3 is connected by guide rod 5 with the adaptation of rack frame 10, power input shaft supports 7 two ends to fix on the frame 6, driving gear 8 is arranged in power input shaft support 7 by power input shaft 11, and the rack on the both sides of rack frame 10 is engaged with driving gear 8 respectively.Two toothed rack symmetrical balances on the rack frame 10 are set, the number of teeth of unilateral rack can not be more than the half of itself number of teeth of driving gear 8 on the rack frame 10, the driving gear 8 need only use the number of teeth of half, when driving force is driven the rack on rack frame 10 by power input shaft 11 by driving gear 8, rack frame 10 will left and right back and forth do horizontal stroke motion, rack frame 10 drives flywheel 3 to rotate by guide rod 5 simultaneously, and driving force is spread out of by power output shaft 4 again.Because driving gear 8 need only use the number of teeth of half, when driving gear 8 is from when going around, driving gear 8 moves the infeed stroke done once back and forth by the rack drives rack frame 10 of the both sides of rack frame 10 respectively, so as to which rack frame 10 drives flywheel 3 to rotate one turn by guide rod 5, so power input shaft 11 is identical with the revolution of power output shaft 4 constant.Because the perimeter dimension of the reference circle of driving gear 8 is approximately 3 times of itself reference diameter size more.So the half of the perimeter dimension of the reference circle of driving gear 8 is up to 1.5 times of itself reference diameter size.So rack frame 10 do back and forth infeed stroke motion apart from size will be 1.5 times of reference diameter size of driving gear 8.When namely guide rod 5 drives the flywheel 3 to rotate back and forth, the stress point of flywheel 3 to itself center of circle is 1.5 times of radius size of reference circle of driving gear 8 apart from size.So as to which the present invention can be in the case where keeping input speed and output speed identical precondition, with the effect for improving driving force 50%.
