Dual-Toothing Pin Ring Transmission for Deformable Power Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transmission systems with traction mechanisms do not effectively utilize a combination of internal and external teeth to optimize power transfer and mechanical engagement, leading to inefficiencies in energy transmission.
Innovation Solution
A transmission system incorporating a pin ring with a gap arrangement of pins or teeth, featuring internal and external toothing systems, where the pin ring is designed to engage alternately with either the internal or external toothing, allowing for efficient power transfer through a staggered or symmetrical gap arrangement, and can be made from materials like manganese-chromium steel alloys for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pin ring with gap arrangement and dual toothing systems is used, then power transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The pin ring is segmented into multiple pins arranged in a circular pattern with gaps between them. This segmentation allows selective engagement with internal or external toothing systems, enabling efficient power transfer while maintaining a relatively simple overall structure. The gaps between pins facilitate deformation and engagement transitions.
Solution Approach 2:
The pin ring is designed with dual toothing systems (internal and external teeth) that can engage with different gear configurations. This multi-functionality allows the same pin ring component to work with various cam disk and housing configurations, improving power transfer efficiency across different operating conditions without requiring multiple specialized components.
2Reliability
If the pin ring is designed for oval or elliptical deformation, then mechanical engagement is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The pin ring is designed to dynamically deform into oval or elliptical shapes during operation. This dynamic deformation enables the pins to alternately engage with internal and external toothing systems, enhancing mechanical engagement and power transfer. The structure accommodates deformation through its gap arrangement and material properties.
Solution Approach 2:
The pin ring's geometric parameters (shape, size) are designed to change during operation. The oval or elliptical deformation alters the engagement parameters between pins and toothing systems, enabling effective power transfer. The material and structural design allow controlled parameter changes without excessive precision requirements.
3Strength
If manganese-chromium steel alloy is used for the pin ring, then durability is improved, but material cost increases
Solution Approach 1:
The pin ring is made from manganese-chromium steel alloy, a composite material combining multiple elements to achieve superior mechanical properties. This alloy provides enhanced strength, wear resistance, and durability for the pins and toothing systems. The material composition is optimized to balance performance requirements with cost considerations.

AI summary
The invention relates to a traction means with an inner toothing and an outer toothing and to a transmission comprising such a traction means. Teeth heads of the inner toothing have a rounded region with a cross-section in the shape of a circular segment, and teeth heads of the outer toothing have a rounded region with a cross-section in the shape of a circular segment. The region between two adjacent teeth heads of the inner toothing is at least as wide as the width of the teeth of the inner toothing, and the region between two adjacent teeth heads of the outer toothing is at least as wide as the width of the teeth of the outer toothing.
