Notched Disc Set Internal Drive Profile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking disc sets require multiple fastening parts and complex assembly processes, limiting their universal application and ease of attachment to various components.
Innovation Solution
A locking disc set with mirror-symmetric discs featuring a central, cylindrical through-hole designed as an internal driving profile, allowing for a non-rotatable connection using a centering bush with a hexagon socket or other profiles, and positioning aids like pin holes for secure and versatile mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central, concentric, and roundly profiled recess (through-hole) is provided in the ratchet disc set, then the mounting device can be simplified, but various additional fastening parts are required which limits universal application
Solution Approach 1:
The through-hole is designed with an internal drive profile (hexagonal, oval, or polygonal recess) that enables universal mounting across different applications. This single structural feature replaces the need for multiple specialized fastening parts, allowing the same ratchet disc set to be mounted on various components without requiring version-specific adaptations.
2Reliability
If special anchoring methods are used (such as drilled holes or central threads), then the ratchet disc set can be securely attached to components, but the design requires multiple versions adapted to different mounting requirements
Solution Approach 1:
The internal drive profile in the through-hole provides a universal mounting interface that secures the ratchet disc set to components without requiring drilled holes, central threads, or other specialized anchoring methods. This single design eliminates the need for multiple versions, as the same structure can be reliably attached to various components across different applications.
3Ease of operation
If an adjustable clamping lever is passed through the ratchet disc arrangement, then adjustment is enabled, but an additional centering device is required to connect and center the two ratchet discs
Solution Approach 1:
The internal drive profile in the through-hole serves dual functions: it provides the mounting interface for the ratchet disc set and simultaneously acts as a centering mechanism. When the mounting device (such as a centering bushing) is inserted into the through-hole, it automatically centers the two ratchet discs relative to each other, eliminating the need for separate centering devices while maintaining adjustability.

AI summary
A set of indexing discs consisting of two indexing discs (1, 2) each with an outer cover surface (2a), wherein the indexing discs (1, 2) are rotatably connected to each other on their inner surfaces by means of opposing interlocking teeth (3) and are axially movable relative to each other, wherein a central cylindrical through-bore (4) aligned with the other indexing disc passes through each of the two indexing discs (1, 2), wherein at least one exit side of the through-bore (4) on the cover surface (2a) of the respective indexing disc (1, 2) is enlarged in diameter and designed as an inner drive profile (5) into which a mounting part can be brought into rotationally fixed engagement, which can be fastened to the component.
