ROTARY ENCODER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027235 titled 'ROTARY ENCODER

Simplified Explanation

The abstract describes a method for mounting a rotary scale member on a part using force-fitting and flexures. The flexures engage with the part and form a friction fit, allowing the rotary scale member to self-locate at an initial radial location. The method also involves tweaking the radial location of the body of the rotary scale member to a new radial location.

  • The rotary scale member has a body with position features defining a scale.
  • At least one mounting flexure is configured to engage the part.
  • The rotary scale member and the part are force-fitted together, displacing the flexure and causing it to engage with the part.
  • The flexure forms a friction fit with the part, allowing the rotary scale member to self-locate at an initial default radial location.
  • The radial location of the body of the rotary scale member can be adjusted to a new radial location.

Potential Applications:

  • This method can be used in various industries where rotary scale members are required, such as manufacturing, robotics, and automation.
  • It can be applied in the assembly of precision instruments, machinery, and equipment that require accurate position sensing.

Problems Solved:

  • The method provides a reliable and secure mounting solution for rotary scale members, ensuring accurate positioning and preventing unwanted movement.
  • It eliminates the need for complex mounting mechanisms or adhesives, simplifying the assembly process.

Benefits:

  • The force-fitting and flexure engagement create a friction fit, ensuring stability and preventing slippage or misalignment.
  • The self-locating feature of the rotary scale member simplifies the assembly process and reduces the chances of human error.
  • The ability to tweak the radial location allows for fine adjustments and precise positioning of the rotary scale member.


Original Abstract Submitted

a method of mounting a rotary scale member on a part, the rotary scale member including a body on which a series of position features defining a scale is provided, and at least one mounting flexure configured to engage the part, the method including: force-fitting the rotary scale member and the part together, whereby the at least one flexure is displaced by the part and thereby urged via a radial reaction force into engagement with the part so as to form a friction fit with the part such that the body of the rotary scale member self-locates at an initial default radial location with respect to the part; and tweaking the radial location of the body relative to the part away from its initial default radial location to a new radial location.
