Baler Roller Assembly Axial Load Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller assemblies in agricultural balers transmit undue axial loads to bearings, leading to potential rotational knock and axial creep, which can affect the efficiency and longevity of the baler's operation.
Innovation Solution
A roller assembly design that mounts the bearing to a housing using a non-circular shaft cross-section and a clamp to prevent axial movement, combined with a housing attachment arrangement where fasteners apply a mounting force perpendicular to the shaft axis, thereby avoiding transmission of axial loads to the bearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bearing is mounted directly to support the shaft, then the bearing provides rotational support, but axial loads are transmitted to the bearing causing rotational knock and axial creep
Solution Approach 1:
The patent introduces a mounting bracket as an intermediary component between the bearing housing and the baler frame. This bracket absorbs and redirects axial loads away from the bearing, allowing the bearing to support radial loads while preventing axial load transmission that causes rotational knock and axial creep.
Solution Approach 2:
The mounting system is segmented into distinct functional components: the bearing supports radial loads, the bearing housing provides structural support, and the mounting bracket handles axial load transmission to the frame. This segmentation allows each component to perform its specific function without interfering with others, preventing harmful axial load transmission to the bearing.
2Reliability
If the housing attachment arrangement uses fasteners in a plane perpendicular to the shaft axis, then axial loads are avoided on the bearing, but the mounting structure becomes more complex
Solution Approach 1:
The mounting bracket serves multiple functions: it attaches the bearing housing to the baler frame, positions the bearing correctly, and critically, redirects axial loads away from the bearing. This multi-functionality justifies the additional structural element by consolidating several requirements into a single component.
Solution Approach 2:
The fasteners are arranged in a plane perpendicular to the shaft axis, representing a dimensional change in the mounting approach. This orientation ensures that the fastening force acts radially rather than axially on the bearing, preventing axial load transmission while maintaining secure attachment to the frame.
