Spindle Drive Damping via Flange Vulcanization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spindle drives generate vibrations and noise due to complex constructions, which are costly and difficult to manufacture, and existing damping arrangements are not effective in fully decoupling these vibrations from the adjusting element.
Innovation Solution
A simplified spindle drive design with flange-like end portions and a damping arrangement formed from elastic material, vulcanized or glued between the end portions, allowing for a compact and easy-to-assemble structure that decouples vibrations and reduces noise by extending the damping arrangement transverse to the spindle drive's longitudinal axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a damping arrangement is added to reduce vibrations and noise, then noise reduction is improved, but device complexity increases
Solution Approach 1:
The damping arrangement is integrated directly into the connection part structure, merging the damping function with the existing connection component. This eliminates the need for separate damping components and reduces overall construction complexity while maintaining effective vibration and noise reduction.
Solution Approach 2:
The connection part serves multiple functions: it provides mechanical connection, structural support, and vibration damping. By making the connection part multi-functional, the patent reduces the number of separate components needed, thereby simplifying the overall construction while achieving noise reduction.
2Object-affected harmful factors
If a damping arrangement is added to decouple vibrations, then vibration decoupling is improved, but manufacturing cost increases
Solution Approach 1:
The damping function is combined with the connection part, eliminating the need for separate damping components and their associated manufacturing processes. This integration reduces manufacturing steps, lowers production costs, and simplifies assembly operations.
Solution Approach 2:
The patent uses elastomeric materials with specific damping properties integrated into the connection part. By selecting appropriate material parameters and integrating them directly into the connection structure, the patent achieves effective vibration decoupling without the need for additional components, thereby reducing manufacturing cost.
3Object-affected harmful factors
If the damping arrangement is extended transversely to reduce noise, then noise reduction is improved, but installation area increases
Solution Approach 1:
The damping arrangement is extended in the transverse direction (perpendicular to the longitudinal axis) rather than increasing the overall length. This dimensional approach allows the damping surfaces to be larger for better vibration decoupling while keeping the compact transverse profile, thus reducing noise without significantly increasing installation space.
Solution Approach 2:
The damping arrangement is positioned within the space between the flange-like end portions of the connection part, utilizing the existing structural space. This nesting approach allows the damping arrangement to have sufficient transverse extension for effective noise reduction while maintaining a compact overall installation footprint.

AI summary
A spindle drive for motor-actuated adjustment of an adjusting element includes a tubular spindle drive housing for a drive unit with a downstream spindle-spindle nut gear unit for generating a linear driving motion. A connection part inserted into one end of the drive housing is connected to an exterior socket via a damping arrangement comprising an elastic damping material. The connection part includes first and second flange-like end portions having confrontingly opposed, spaced apart front sides sandwiching the damping arrangement 4 which is connected to the end portion front sides by vulcanization and/or gluing. The socket is carried on the second end portion remote from the damping arrangement 4.
