Dual-Diagonal Roller Retainer Prevents Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller retainers face issues such as rollers contacting each other and non-loading surfaces colliding with the track, leading to noise, stress loss, and instability, with existing solutions either reducing load capacity or being prone to falling off due to excessive thickness or single diagonal mounting.
Innovation Solution
A roller retainer comprising a first and second guiding frame, integrally connected in a vertically staggered manner along two diagonals, maintains space between non-loading surfaces and the track, preventing collisions and ensuring stability without increasing the space between rollers, using flexible materials like plastic or rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single diagonal stopping annular retainer is mounted on the roller, then the structure is simple, but the retainer is prone to falling off and rollers may be jammed
Solution Approach 1:
The retainer is divided into two separate retaining members mounted on opposite diagonals of the roller, with each member having its own groove. This segmentation allows each member to independently stabilize the roller without interfering with the other, preventing the roller from inclining or falling off while maintaining structural simplicity
Solution Approach 2:
The solution transitions from a single-diagonal mounting to a dual-diagonal mounting arrangement, adding spatial distribution in multiple dimensions. The two retaining members are positioned at opposite diagonals, creating a balanced three-dimensional configuration that enhances stability without significantly increasing complexity
2Reliability
If the stopping annular retainer is made excessively thick to hold the roller stably, then the roller is prevented from falling off, but the space between rollers increases and load capability decreases
Solution Approach 1:
The retainer function is segmented into two separate retaining members, each with reduced individual thickness. The combined effect of two thinner members provides the necessary stability without requiring a single thick member, thereby reducing the space occupied by retainers and allowing more rollers to fit in the track
Solution Approach 2:
The stabilizing function is distributed across two retaining members positioned at opposite diagonals. By combining the stabilizing effect of multiple thinner members rather than using one thick member, the system achieves the required roller stability while minimizing the space consumed by retainers, thus preserving load capability
3Ease of operation
If the groove is formed in the loading surface of the rollers to allow space rings to run smoothly, then the space rings can circulate, but the contacting length of rollers is reduced and load capability decreases
Solution Approach 1:
The groove is extracted from the loading surface and relocated to the non-loading surface of the roller. This allows the space rings to run smoothly along the groove for proper circulation while the loading surface remains intact and fully engaged with the track, preserving maximum contacting length and load capability
Solution Approach 2:
The groove is positioned specifically on the non-loading surface where it is not needed for load bearing, while the loading surface maintains its full contacting capability. This local differentiation allows the groove to serve its circulation function without compromising the load-bearing function of the roller

AI summary
A roller retainer mounted on a roller comprises a first guiding frame and a second guiding frame that are integrally connected with each other in a vertically staggered manner. The first guiding frame and the second guiding frame are located along the two diagonals of the roller respectively. The thickness of the first guiding frame and the second guiding frame is utilized to keep the space between the two non-loading surfaces of roller and a track. The roller retainer can further keep the space between each roller. Thereby, the roller retainer can prevent the rollers from contacting each other; the loading surfaces can still contact the track and the non-loading surfaces are prevented from colliding with and rubbing against the track, thus reducing the noise and ensuring the moving direction.
