Abstract
The claimed subject matter provides an anti-backlash nut for use with a leadscrew. The nut can include two or more threaded sections and at least one semi-flexible section. The anti-backlash nut can be of one-piece construction and utilize the one or more flexible or biasing sections to apply one or more forces or offsets to the threaded sections to mitigate backlash.
Claims20
An anti-backlash nut, comprising:
- a first section having a first inner diameter and a first outer geometry, the first inner diameter is threaded to interface with a first external thread portion;
- a second section having a second inner diameter, a second outer geometry, and a partially yieldable portion;
- and
- a third section having a third inner diameter and a third outer geometry, the third inner diameter is threaded to interface with a second external thread portion,
- wherein the first section and the third section are connected at least by the second section, and
- wherein the second section biases the first section and third section against one another at least based in part on one or more of the first external thread portion and the second external thread portion.
3 more elements
A method of producing an anti-backlash nut, comprising:
- producing a first section, the first section is hollow with an internal threading pattern;
- producing a second hollow section, the second section is hollow and includes at least a semi-flexible portion;
- producing a third section, the third section is hollow with the internal threading pattern;
- and
- manipulating the second hollow section to offset the first hollow section with respect to third hollow section.
2 more elements
A self-aligning nut for engagement with external threading, comprising:
- at least one central biasing portion of annular construction including one or more cut-out portions that facilitate controlled deformation of the central biasing portion;
- and
- two or more threaded distal portions of annular construction joined by the at least one central biasing portion.
