Pressure Roller Tilting Mechanism via Pendular Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure rollers for textile machines require additional components to achieve tilting functionality, complicating their construction and installation.
Innovation Solution
A pressure roller design featuring a grooved ball bearing pivotably mounted about a tilting axis, with a pendulum sleeve directly interacting with the support bolt, eliminating the need for a separate tilting axis component and incorporating two sleeve halves that can be produced efficiently through plastic injection molding or as metal parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate tilting axis component is used to enable the deep groove ball bearing to tilt, then the tilting functionality is achieved, but the device complexity increases
Solution Approach 1:
The tilting axis functionality is merged with the existing support bolt and pendulum sleeve components. The pendulum sleeve is formed as an integral part of the support structure, eliminating the need for a separate tilting axis component. The support bolt directly forms the tilting axis through its interaction with the pendulum sleeve, reducing the total number of parts while maintaining the required tilting capability.
Solution Approach 2:
The support bolt serves multiple functions: it provides structural support, enables rotation, and forms the tilting axis. The pendulum sleeve simultaneously provides bearing support and enables tilting movement. This multi-functionality reduces the need for dedicated components for each function, simplifying the overall device structure.
2Adaptability or versatility
If additional components are added to achieve tilting, then the tilting movement is enabled, but the installation efficiency decreases
Solution Approach 1:
The tilting mechanism is integrated into the existing support structure using the pendulum sleeve and support bolt combination. This merging of functions reduces the number of separate components that need to be assembled, thereby simplifying the installation process and improving installation efficiency while maintaining full tilting capability.
3Device complexity
If the pendulum sleeve is made as a single piece, then the structure is simpler, but the manufacturing flexibility is reduced
Solution Approach 1:
The pendulum sleeve is divided into two separate halves that can be manufactured independently using plastic injection molding or other suitable processes. This segmentation allows for greater manufacturing flexibility, easier assembly, and the possibility of using different materials or production methods for each half, while the two halves come together to form the complete pendulum sleeve structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the construction and installation of pressure rollers by integrating the tilting mechanism within the existing components, minimizing additional parts and ensuring stable, limited tilting movement of the deep groove ball bearing.
Implementation Method 1
The support sleeve is rotatably mounted via a grooved ball bearing relative to a support bolt
Implementation Method 2
the deep groove ball bearing is mounted such that it can be tilted relative to the supporting bolt transversely to its longitudinal axis

AI summary
A pressure roller comprises a groove ball bearing (3), which is mounted pivotably about a tilt axis (K) that is perpendicular to the rotation axis (R) of the bearing, and a supporting pin (2), which is arranged orthogonally to the tilt axis (K), wherein the groove ball bearing (3) is coupled via a pendular sleeve (9) to the supporting pin (2). The tilt axis (K) is implemented by direct cooperation of the pendular sleeve (9) with the supporting pin (2), wherein the pendular sleeve (9) has two sleeve halves (10, 11), which each have a jacket section (12) and a journal (17) rigidly connected thereto, said journal engaging with a bore (18) in the supporting pin (2).
