Guide Carriage Roller Body Guide Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide carriages for elongated guide rails are costly to manufacture and require complex grinding processes, with multiple parts that can be prone to deformation and material wastage, leading to inefficiencies in design and functionality.
Innovation Solution
A guide carriage design featuring a separate rolling body guide part with a constant cross-sectional guide section that engages behind the raceway insert, reducing the main body's complexity and allowing for a more cost-effective production process, along with a plastic or elastomer guide section for reduced noise and improved sealing, and a raceway insert with adjustable bearing surfaces for compact design and efficient grinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the main body is used to delimit the gap preventing rolling elements from falling out, then the guide carriage structure is integrated, but the grinding work on the main body becomes complex and costly
Solution Approach 1:
The guide carriage is divided into separate functional components: the main body and the rolling body guide part. The rolling body guide part, which includes the guide section that engages behind the raceway insert to prevent rolling elements from falling out, is separated from the main body. This segmentation allows the main body to be manufactured without complex grinding operations, while the guide section can be produced more simply and attached to the main body, thereby reducing overall manufacturing cost and complexity.
2Adaptability or versatility
If multiple individual parts are used in the guide carriage, then functionality is enhanced, but the number of parts increases leading to higher complexity
Solution Approach 1:
The rolling body guide part is merged with the main body through attachment, creating an integrated assembly that functions as a complete guide carriage. The guide section of the rolling body guide part engages behind the raceway insert to provide the retention function, while the attached configuration reduces the number of separate components compared to fully discrete designs, balancing functionality with simplified assembly.
3Object-affected harmful factors
If the guide section is made of plastic or elastomer, then noise is reduced and sealing is improved, but the structural rigidity may be compromised
Solution Approach 1:
The guide carriage employs composite material construction: the main body and raceway insert are made of rigid metal materials to provide structural strength and rigidity, while the guide section is made of plastic or elastomer materials to reduce noise and improve sealing. This composite approach allows each component to be made from the material best suited for its specific function, achieving both noise reduction and structural integrity.
