Linear Actuator Assembly with Reverse-Inserted Threaded Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of linear actuators with threaded shafts is inefficient due to the complexity of components and the need for custom scaling, which hampers manufacturing efficiency and convenience.
Innovation Solution
A semi-finished product assembly method where a case, main gear, and main gear bearing are formed, allowing a threaded shaft to be reversely assembled with one end inserted into the main gear for restriction, enabling efficient assembly and adjustment of the threaded shaft based on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the linear actuator includes complex elements such as controllers and multiple transmission elements, then the power output can be detected or adjusted, but the assembly difficulty increases
Solution Approach 1:
The linear actuator is divided into modular components: a motor module containing the motor and transmission elements, a controller module with detection components, and a threaded shaft module. This segmentation allows each module to be assembled and tested independently, reducing overall assembly difficulty while maintaining full functionality for power output detection and adjustment.
Solution Approach 2:
The controller is designed to perform multiple functions: detecting power output parameters, adjusting transmission ratios, and controlling motor operation. By integrating these functions into a single multi-functional controller rather than separate components, the device achieves reliable power output detection and adjustment without proportionally increasing assembly complexity.
2Adaptability or versatility
If the scale of the threaded shaft is changed based on demands, then the linear actuator can be customized, but the manufacture efficiency decreases
Solution Approach 1:
Standardized threaded shafts with common scales are pre-manufactured and stored in inventory. When assembling linear actuators, these pre-made threaded shafts are selected and installed rather than custom-manufacturing each one. This preliminary preparation maintains customization capability for different applications while dramatically improving manufacturing efficiency through standardized production batches.
Solution Approach 2:
The patent provides guidance on selecting appropriate threaded shaft parameters (scales, diameters, pitches) based on specific application demands. By establishing standardized parameter ranges and selection criteria, the system maintains adaptability for different applications while enabling efficient production through standardized components within these parameter ranges.

AI summary
A linear actuator assembling method includes a semi-finished product assembling step and a threaded shaft assembling step. The semi-finished product assembling step is to form a semi-finished product, and the semi-finished product includes a case, a main gear, and a main gear bearing. The main gear and the main gear bearing are surrounded and restricted by the case, and the main gear bearing is sleeved on the main gear. In the threaded shaft assembling step, a threaded shaft is reversely assembled, and one end of the threaded shaft is inserted into the main gear to allow the end of the threaded shaft to be restricted by the main gear.
