Abstract
Gear systems provide backlash control at low loading and effective load carrying at increased loading. A gear system with backlash control includes at least two meshing gears. One of the gears has a gear section configured for carrying loads and another gear section configured to control backlash. The gear sections are connected together by a compliant section that has features that reduce stiffness so that the gear sections are moveable relative to each other. One gear section is biased relative to the other gear section so that its teeth are preloaded against the teeth of the first gear.
Claims20
A gear system with backlash control comprising:
- a first gear having first gear teeth;
- and
- a second gear meshing with the first gear wherein:
- the second gear has a first gear section configured for carrying loads and a second gear section configured to control backlash, wherein the first gear section has a first axial thickness that is substantially larger than a second axial thickness of the second gear section;
- the first gear section is connected with the second gear section by a compliant section having features around the compliant section that reduce stiffness so that the second gear section is moveable relative to the first gear section;
- and
- the second gear section is biased relative to the first gear section so that teeth of the second gear section are preloaded against the first gear teeth of the first gear.
A gear system with backlash control comprising:
- a first gear having first gear teeth;
- and
- a second gear meshing with the first gear wherein:
- the second gear has a first gear section with second gear teeth configured for carrying loads and a second gear section with third gear teeth configured to control backlash;
- the first gear section is connected with the second gear section by a compliant section having a generally cylindrical shape with features around the compliant section that reduce stiffness so that the third gear teeth of the second gear section are moveable relative to the second gear teeth of the first gear section;
- and
- the second gear section is biased relative to the first gear section so that the third gear teeth of the second gear section are preloaded against the first gear teeth of the first gear and the third gear teeth are disposed different than the second gear teeth relative to the first gear teeth when the gear system is unloaded.
A gear system with backlash control comprising:
- a first gear having first gear teeth;
- and
- a second gear meshing with the first gear wherein:
- the second gear has a first gear section with second gear teeth configured for carrying loads and a second gear section with third gear teeth configured to control backlash, wherein the first gear section has a first axial thickness that is substantially larger than a second axial thickness of the second gear section;
- the first gear section is connected with the second gear section by a compliant section having a generally cylindrical shape with openings around the compliant section that reduce stiffness so that the third gear teeth of the second gear section are moveable relative to the second gear teeth of the first gear section;
- the second gear section is biased relative to the first gear section so that the third gear teeth of the second gear section are preloaded against the first gear teeth of the first gear and the third gear teeth are disposed different than the second gear teeth relative to the first gear teeth when the gear system is unloaded;
- and
- wherein the first gear section is more rigid than the second gear section so that the first gear section carries the loads at increased loading of the gear system.
