Ball Screw Riveting Transmission Layout for Compact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riveting transmission devices have a large volume due to complicated assembly relationships between components, making them unsuitable for use in narrow spaces and requiring high assembly accuracy for proper function.
Innovation Solution
A riveting transmission device with a simplified assembly structure, featuring a bearing front seat, a bearing rear seat, and a ball screw rod assembly, where the screw sleeve gear is arranged outside the rear seat, and limiting structures prevent disengagement of the support member from the rear seat, allowing for compact design and efficient linear motion conversion from circular motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a screw sleeve gear is provided between the front bearing seat and rear bearing seat, then the connection between components is achieved, but the volume of the whole riveting transmission device becomes relatively large
Solution Approach 1:
The screw sleeve gear is moved from the internal space between the front and rear bearing seats to the external surface of the rear bearing seat. This dimensional relocation eliminates the need for internal clearance and allows the gear to be positioned in the external dimension, thereby reducing the overall volume of the riveting transmission device while maintaining the connection function.
2Ease of manufacture
If a screw sleeve gear is provided between the front bearing seat and rear bearing seat, then the connection between components is achieved, but the assembly relationship becomes complicated
Solution Approach 1:
The screw sleeve gear is extracted from the complex internal assembly between the front and rear bearing seats and positioned externally on the rear bearing seat. This extraction simplifies the assembly relationship by eliminating the need for precise internal positioning and multiple connection points, reducing the overall complexity of the assembly process.
3Reliability
If the ball screw rod assembly is positioned between the front and rear bearing seats, then the transmission function is achieved, but high assembly accuracy is required
Solution Approach 1:
The screw sleeve gear is repositioned from the internal dimension (between bearing seats) to the external dimension (on the surface of the rear bearing seat). This dimensional change allows for more flexible positioning and reduces the stringent assembly accuracy requirements, as the gear can be mounted externally without requiring precise internal alignment between the bearing seats.

AI summary
The invention relates to the technical field of riveting transmission, and provides a riveting transmission device. The riveting transmission device includes a bearing rear seat, a bearing front seat and a ball screw rod assembly. The bearing front seat includes a vertical portion, a first horizontal portion and a second horizontal portion. The ball screw rod assembly includes a screw rod assembly, a support member, a screw sleeve gear, a first bearing, and a second bearing. The screw rod assembly is disposed at the first horizontal portion. One end of the support member abuts against the first bearing, and the screw sleeve gear is sleeved at the other end of the support member, and is located outside the bearing rear seat. A first limiting structure is arranged on the bearing rear seat, and a second limiting structure is arranged on the support member. Two ends of the second bearing respectively abut against the first limiting structure and the second limiting structure. The bearing front seat, the bearing rear seat and the ball screw rod assembly are sequentially sleeved, and the overall assembly structure is simple. Moreover, the screw sleeve gear is arranged outside the bearing rear seat, so that the riveting transmission has a shortened overall length, a compact structure, and a smaller occupied space.
