Bobbin Pot Bearing Locking Structure for Axial Spindle Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bobbin pot bearings in twisting machines, particularly double-twisting and cabling machines, face issues with securing the bobbin pot reliably on the spindle, leading to potential displacement and damage during operation, especially when processing heavy yarns.
Innovation Solution
A bobbin pot bearing design featuring a bearing bush with latching projections and a locking mechanism that secures the bobbin pot base to the spindle, preventing unintentional lifting and ensuring a positive connection through a combination of form-fitting and locking elements, including a connecting sleeve and thread brake for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frictional connection is used to secure the bearing bushing to the bearing body, then the structure is simple, but the reliability is insufficient when processing heavy yarns
Solution Approach 1:
The bearing bushing is divided into multiple functional sections: a first bearing section with detent projections for axial positioning, a second bearing section for radial support, and a locking section with latching projections. This segmentation allows each section to perform its specific function optimally, with the detent projections preventing axial displacement and the latching projections providing secure locking, thereby resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The detent projections and latching projections are designed to be movable between engaged and disengaged positions. The detent projections can move radially to engage or disengage from the bearing body, while the latching projections can move axially to lock or unlock the bobbin pot base. This dynamic design enables reliable securing during operation while allowing easy mounting and dismounting, resolving the contradiction between securing reliability and operational flexibility.
2Reliability
If a secure locking mechanism is implemented to prevent bobbin pot displacement, then the reliability improves, but the ease of operation deteriorates due to complex locking procedures
Solution Approach 1:
The mounting and dismounting process is designed to be self-servicing through the automatic engagement of detent projections and latching projections. When the bobbin pot base is mounted on the bearing bushing, the detent projections automatically engage with the bearing body and the latching projections automatically lock into place, securing the assembly without requiring additional fastening operations. For dismounting, the thread brake simply needs to be loosened, which automatically releases the latching projections, enabling tool-free removal and resolving the contradiction between secure locking and ease of operation.
3Stability of the object's composition
If the bearing bushing is securely locked to the spindle, then the stability improves, but the ease of repair worsens due to difficult disassembly
Solution Approach 1:
The locking mechanism uses movable detent projections and latching projections that can be easily engaged and disengaged. The detent projections move radially to provide stable locking during operation, while the latching projections move axially to secure the assembly. For repair or replacement, loosening the thread brake automatically releases the latching projections, allowing the bearing bushing to be removed without complex disassembly procedures, thus resolving the contradiction between assembly stability and ease of repair.

AI summary
The invention relates to a bobbin pot bearing for a twisting machine, in particular a double-wire twisting machine or a cabling machine, with a bearing bushing for a positive-locking connection of a bobbin pot base to a spindle in the direction of rotation. To provide a bobbin pot bearing for a twisting machine, in particular a double-wire twisting machine or a cabling machine, which ensures reliable positioning of the bobbin pot on the spindle, it is provided that a first bearing section of the bearing bushing has, for a positive-locking connection in the axial direction with a first bearing body arranged on the spindle, detent projections extending from an inner side of the bearing bushing at a distance from a shoulder defining the first bearing section. These detent projections are movable between a locking position and an unlocking position.A second bearing section of the bearing bushing, extending in the longitudinal direction to the first bearing section, is designed to form a positive-locking connection with the coil pot bottom that can be locked in the axial direction, and a locking means is arranged on the coil pot bottom that, in an operating position of the coil pot bottom, defines the detent projections in the locking position.
