Sheet Metal Cylinder Synchronization Profile Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sheet metal cylinders with synchronization profiles tend to deform under centrifugal forces at high speeds, especially in disk carriers with large axial lengths, leading to improper deformation when accommodating multiple shift elements.
Innovation Solution
The synchronization profile is discontinued in the axial direction and replaced with a circumferential supporting element, preferably a non-profiled axial segment with a flat annular cross-section, which acts as a stabilizing binding element to absorb tensile loads and prevent deformation.

1Length of moving object
If the synchronization profile extends over the entire axial length of the disk carrier, then the disk carrier can accommodate shift elements along its length, but the cylinder becomes soft and deforms in tangential and radial directions under centrifugal forces at high speeds
Solution Approach 1:
The synchronization profile is divided into multiple axial segments separated by non-profiled supporting elements. This segmentation allows the cylinder to maintain its function of accommodating shift elements while preventing continuous deformation along the axial length. The supporting elements create discrete sections that resist centrifugal forces independently.
Solution Approach 2:
Different axial regions of the cylinder are given different properties: some regions have synchronization profiles for engaging shift elements, while others have non-profiled supporting elements for structural stability. This local differentiation allows the cylinder to simultaneously achieve the required functional length and resistance to deformation under centrifugal loading.
2Strength
If the synchronization profile is discontinued and replaced with a circumferential supporting element, then the tensile load in the tangential direction is absorbed and deformation is prevented, but the continuous synchronization function along the axial length is interrupted
Solution Approach 1:
The synchronization profile is segmented into discrete axial sections separated by non-profiled supporting elements. Each segmented portion maintains synchronization capability while the supporting elements provide structural reinforcement to resist centrifugal forces, thus balancing continuous function with localized strength enhancement.
Solution Approach 2:
The non-profiled axial segments act as intermediary elements between synchronized sections. These intermediaries serve dual purposes: they provide the structural strength needed to resist deformation under centrifugal loading while allowing the adjacent profiled sections to maintain their synchronization function with shift elements.
