34, axle spring 34 is externally provided with axial screw block 35.Same can also set same axle at the both ends of output drive wheel 13.1
To floating equilibrium structure.The floating structure of multiple planetary gears is simple, can be improved with the manufacture alignment error of each gear of effective compensation
Transmission quality, axial screw block adjustable axle is adjusted to elastic force.
Cod 33 is in axial support columns external gear.When using helical gear, when cylindrical external gear is also driven injustice
During weighing apparatus, the out-of-balance force on helical gear, the elastic force of axle spring 34 pushes away cylindrical external gear axial displacement and is allowed to tend to be balanced, adjustment
Cylindrical external gear axially position can be made suitable for axial screw block 35 and the size of floating equilibrium power.When error occurs for transmission, gear
On radial load can change, as a result its axial force can also change.When driving error increases axial force, then axially
Spring 34 is compressed, helical gear axial movement, reduces engagement exposure level, on the contrary then increase engagement exposure level.Adjust axial screw
The adjustable elastic force of block 35.Planet wheel spindle is set to improve transmission quality to floating equilibrium structure.
Embodiment seven
It is to rotate energy completely in synthesis caused by the setting speed wheel (3) and easy variable speed wheel (4) as shown in Figure 8
Ground is output under the conditions of driving synchronous rotational speed wheel and can fully met embodiment during gear drive bending contact strength, the knot
Structure be the revolving member that easy variable speed wheel (4) is connected can only be set on the basis of embodiment three i.e. Fig. 4 it is poor to input planet
In motivation structure.The component of output drive wheel 13 is eliminated using this kind of structure, design of part is reduced, reduces cost.
The structure of embodiment seven and above-mentioned other embodiment is essentially identical, and its main distinction is：In setting speed wheel and
Synthesis rotation can fully be output under the conditions of driving synchronous rotational speed wheel and can fully meet tooth caused by easy variable speed wheel
During wheel transmission bending contact strength, the revolving member that easy variable speed wheel is connected can be only set to input planetary cross-country power mechanism
It is interior, and without the revolving member being connected with easy variable speed wheel in output planetary differential attachment.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
