A power to close to the movement of 1 direction of spiral multilayer curved tooth cylindrical gear.Spring can be used in elastic element 7, can also use other elasticity
Material.
Spiral multilayer curved tooth cylindrical gear 1 is furnished with elevating mechanism, when it is rotated around output shaft, 1 edge of spiral multilayer curved tooth cylindrical gear
The axis direction of output shaft is mobile, is connected between spiral multilayer curved tooth cylindrical gear 1 and output shaft by spline and keyway, output shaft with
Power device connection, elevating mechanism can be sliding rail and sliding block, and spiral multilayer curved tooth cylindrical gear 1, output shaft, power device are respectively positioned on
On the sliding block, sliding block can be free to slide on the slide rail, and elevating mechanism may be the screw thread that output shaft is arranged in, output shaft and frame
Frame is threadedly coupled, and when output shaft rotates under the action of power device, output shaft is moved axially, and then drives spiral multilayer bent
Line gear 1 is rotated and is moved axially, and the thread pitch on output shaft should be with the multilayer spiral structure on spiral multilayer curved tooth cylindrical gear 1
Screw pitch it is identical, with guarantee both the rate of climb consistency.
First gear 2 and the first synchronising (connecting) rod 13 can be directly hinged by pin shaft, can also be in first gear 2
A upper coaxial fixed synchronizing wheel, synchronizing wheel are hinged by pin shaft with the first synchronising (connecting) rod 13 again.Second gear 10 with
Between first synchronising (connecting) rod 13, between second gear 10 and the second synchronising (connecting) rod 14, third gear 8 and the second synchronising (connecting) rod 14 it
Between connection type it is identical as aforesaid way, details are not described herein.
Working principle is：Spiral multilayer curved tooth cylindrical gear 1 makees constant angular velocity under the action of output shaft and power device
Rotary motion, and move axially；First gear 2 is meshed with spiral multilayer curved tooth cylindrical gear 1, and first gear 2 is more with spiral by it
The irregular influence of reference diameter at 1 contact point of layer curved tooth cylindrical gear, first gear axis 3 make corresponding horizontal round-trip shifting
It is dynamic, at the same first gear 2 by its with reference diameter is irregular at 1 contact point of spiral multilayer curved tooth cylindrical gear influences to make angle
The irregular rotary motion of speed；First gear 2 drives second gear 10 to make same angular speed not by synchronization mechanism
The rotary motion of rule variation；Second gear 10 is made same angular speed by synchronization mechanism drive third gear 8 and is irregularly become
The rotary motion of change, third gear 8 are meshed with round master gear 11, and it is irregular also to make angular speed for round master gear 11 then
The rotary motion of variation, and make angular speed output.
In conclusion structure is simple by means of the above-mentioned technical proposal of the utility model, production cost is low, and spiral shell can be read
The angular speed of rotation Multiple Stage Curve gear changes and passes through round master gear output.
