Split Bearing Arrangement With Oblique Clamping Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split bearing arrangements impose high mechanical loads on sliding bearings due to the perpendicular orientation of clamping surfaces and counter clamping surfaces, which can lead to increased stress and reduced lifespan of the bearings during operation.
Innovation Solution
The clamping surfaces of the bearing cover are oriented obliquely at an angle not equal to 90° relative to the longitudinal extension of the connecting elements, with counter clamping surfaces oriented perpendicularly, and projections are arranged at a distance of at least 150% of the maximum projection height, reducing tension and stress on the sliding bearings.

Engineering Contradiction Analysis
1Reliability
If clamping surfaces and counter clamping surfaces are oriented perpendicularly to the connecting elements, then the bearing arrangement can be assembled precisely and the dividing plane is prevented from opening, but high mechanical loads are imposed on the sliding bearings
Solution Approach 1:
The patent changes the orientation angle parameter of the clamping surfaces relative to the connecting elements. Instead of being perpendicular (90°), the clamping surfaces are oriented at an oblique angle, which modifies the force distribution and reduces mechanical loads on the sliding bearings while maintaining assembly precision and preventing dividing plane opening.
Solution Approach 2:
The patent introduces asymmetry in the clamping surface orientation. The clamping surfaces are designed with different orientations compared to the counter clamping surfaces, creating an asymmetric configuration that optimizes force distribution and reduces bearing loads while maintaining functional requirements.
2Manufacturing precision
If projections are arranged close to the clamping surfaces, then assembly precision is improved, but tensions in the bearing housing increase
Solution Approach 1:
The patent positions projections in a specific spatial arrangement at a distance of at least 150% of the maximum projection height from the clamping surfaces. This spatial positioning in three-dimensional space optimizes both assembly precision and tension distribution, resolving the contradiction between close positioning for precision and distant positioning for reduced tension.
