Ball Bearing Ball Arrangement With Flow-Stopping Jig Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ball arranging method for ball bearings requires multiple steps and time for conveyance, leading to inefficiencies and increased risk of ball scratches due to the separation of ball collecting and inserting steps.
Innovation Solution
A method that integrates ball inserting and separating steps by using a flow stopping jig to hold balls in place, allowing continuous operation without the need for a separate ball collecting step, and includes mechanisms to enlarge the annular space and incline rings for smooth ball placement and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate ball collecting step is performed between ball inserting and ball separating steps, then balls can be arranged at equal intervals, but the number of steps increases and workability deteriorates
Solution Approach 1:
The patent merges the ball inserting step and ball separating step into a continuous operation. The inner ring is moved to enlarge the annular space for ball insertion, then returned to its original position to automatically separate the balls at equal intervals, eliminating the need for a separate ball collecting step while maintaining arrangement precision
Solution Approach 2:
The patent uses dynamic movement of the inner ring to achieve both ball insertion and separation. By moving the inner ring to enlarge the annular space during insertion and then returning it to the original position, the balls are automatically separated at equal intervals without additional steps, improving workability while maintaining precision
2Manufacturing precision
If ball inserting and ball separating steps are performed at different positions with conveyance, then balls can be arranged at equal intervals, but time for conveyance increases and productivity decreases
Solution Approach 1:
The patent combines ball inserting and ball separating operations at the same position by continuously moving the inner ring. This eliminates conveyance time between steps while maintaining equal interval arrangement through the dynamic positioning and return movement of the inner ring
Solution Approach 2:
The patent achieves continuous operation by eliminating idle conveyance time. The inner ring moves to enable ball insertion, then immediately returns to separate the balls, creating a continuous useful action sequence without interruption or transportation delays, thereby improving productivity
3Manufacturing precision
If multiple steps are performed for ball arranging, then balls can be arranged at equal intervals, but the number of operations increases and workability deteriorates
Solution Approach 1:
The patent merges multiple operations (ball inserting and ball separating) into a single continuous process by utilizing the movement and return movement of the inner ring. This reduces the number of discrete steps while maintaining equal interval arrangement precision
Solution Approach 2:
The patent performs the ball inserting action preliminarily by moving the inner ring to enlarge the annular space, then uses the return movement to automatically achieve ball separation. This preliminary positioning action enables both insertion and separation without requiring additional time-consuming steps

AI summary
A ball arranging method for a ball bearing includes in this order a ball inserting step of inserting a plurality of balls into one region along a circumferential direction of an annular space formed between an inner ring and an outer ring, a flow stopping step of placing a flow stopping jig on a circumferentially outer side of the one region in the annular space so as to hold the inserted balls within the one region, and a ball separating step of sequentially inserting, in an axial direction, tip ends of a plurality of working arrows protruding correspondingly to a number of the balls between the balls while the flow stopping jig is removed from the annular space from a state of being placed in the annular space, so as to arrange the balls at equal intervals in the circumferential direction.
