Loom Bearing Structure Alignment and Assembly Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing loom designs require complex and time-consuming adjustments of the bearing structure to align the center of the bearing with the support shafts, leading to increased operator burden and potential bending issues due to the long mounting beam, complicating the assembly process.
Innovation Solution
The loom incorporates a support body with a position adjusting surface parallel to the attaching surface, allowing for easier alignment of the bearing structure's center with the support shafts, eliminating the need for adjustments and simplifying the bearing structure configuration by integrating the shaft support part and base part into a single structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bearing structure is mounted on a long beam extending in the weaving width direction, then the bearing structure can support the rocking shaft, but bending may occur on the beam over its length direction
Solution Approach 1:
The support body is divided into multiple segments: a beam extending in the weaving width direction, and multiple support portions extending in the upper and lower direction at different positions along the beam. This segmentation allows the long beam to be reinforced at specific intervals without increasing overall length, preventing bending while maintaining structural integrity.
2Manufacturing precision
If the bearing structure is configured to allow positional adjustment of the shaft support part, then the center of the bearing can be aligned with the shaft center of the support shaft, but the configuration becomes complicated and the mounting operation becomes time-consuming
Solution Approach 1:
The shaft support part is designed with a preliminary adjustable structure that includes adjustment holes and positioning pins. This preliminary configuration allows for easy alignment and fixation of the bearing center with the shaft center during initial assembly, eliminating the need for complex post-assembly adjustments while maintaining high alignment precision.
3Manufacturing precision
If the bearing structure allows positional adjustment, then alignment can be achieved, but the mounting operation becomes troublesome and time-consuming
Solution Approach 1:
The support body incorporates self-aligning features such as guide surfaces and positioning mechanisms that automatically guide the shaft support part into the correct position during assembly. This self-service design reduces the need for manual adjustment operations, significantly decreasing mounting time while maintaining alignment precision.
4Device complexity
If the shaft support part and base part are combined into a single structure, then the bearing structure configuration is simplified, but positional adjustment becomes more difficult
Solution Approach 1:
While maintaining an integrated single-structure design, the support body is segmented into functional zones: a beam portion extending in the weaving width direction and multiple support portions extending in the upper and lower direction. This segmentation within unity provides inherent adjustment capabilities through the geometric arrangement of support portions, simplifying the overall configuration while preserving ease of positional adjustment.

AI summary
A loom includes a pair of support shafts each provided to each of a pair of side frames and configured to rock, a rocking shaft connected to both the support shafts and bridged between the support shafts, a bearing structure comprising a bearing configured to rotatably support the rocking shaft, and a support body having an attaching surface, which is a surface to which the bearing structure is attached, and provided to extend in a weaving width direction. The support body has a position adjusting surface parallel to the attaching surface on at least one of both ends in a length direction.
