Direct Drive Transmission End Cover Layout for Reliable Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing direct drive transmission systems face challenges in compact motor structures, where the end covers of the base and slide are zigzag staggered, leading to a small limiting contact area and poor reliability.
Innovation Solution
A direct drive transmission system is designed with a mover unit and a stator unit, featuring parallel first and second guide rails and orthographic plane structures on the end covers, which form a slidable connection and include a limiting structure for enhanced reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the end covers of the base and slide are zigzag staggered to achieve compact structure, then the motor structure becomes compact, but the limiting contact area becomes small and reliability deteriorates
Solution Approach 1:
Instead of staggering the end covers in a zigzag pattern, the patent inverts the arrangement by positioning the first end cover and second end cover in a collinear (aligned) configuration. This inversion of the traditional staggered layout enables the limiting structure to extend along the motion direction and contact both end covers simultaneously, thereby increasing the limiting contact area while maintaining compact motor structure.
2Volume of moving object
If the end covers are arranged in a zigzag staggered pattern, then the structure appears compact, but the structure becomes complicated and assembly difficulty increases
Solution Approach 1:
The patent inverts the conventional zigzag staggered arrangement of end covers to a collinear configuration. This inversion simplifies the structural design by eliminating the complex staggered geometry, making the end covers easier to manufacture and assemble while still achieving compact motor structure through optimized spatial arrangement of other components.
3Reliability
If a limiting structure is added to increase limiting area, then reliability improves, but device complexity increases
Solution Approach 1:
The limiting structure is designed to serve multiple functions simultaneously: it provides the limiting function by contacting the end covers, acts as a structural support element, and helps define the motion trajectory of the mover unit. This multi-functionality allows the limiting structure to increase reliability without proportionally increasing device complexity, as it consolidates several functions into a single component.
Solution Approach 2:
The limiting structure is integrated with the stator assembly and end cover arrangement, merging the limiting function with the existing structural elements. By combining the limiting function with the collinear end cover configuration and guide rail system, the patent achieves enhanced reliability without adding independent complex subsystems.

AI summary
The disclosure provides a direct drive transmission system. The direct drive transmission system includes a mover unit and a stator unit driving the mover unit to move. The stator unit includes a stator assembly, two first end covers, and two first guide rails. The mover unit includes a mover assembly, two second end covers, and two second guide rails. The direct drive transmission system further includes a limiting structure. An end of the limiting structure close to each of the second end covers is located between the two second end covers. The stator assembly drives the mover assembly to cause the second guide rail to move along the first guide rail, such that the second end cover contacts a side wall of the limiting structure to realize limiting.
