Electric Cylinder Buffering Structure for Impact Load Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric cylinders used in engineering machinery experience impact loads, leading to cyclic pulsating loads on screws and nuts, which significantly reduces their service life. Additionally, the dimensions of single-stage electric cylinders often fail to meet requirements for use in situations with limited installation space.
Innovation Solution
An electric cylinder with a buffering device is designed, which includes a cylinder barrel, a linear motion component, and a buffering device. The buffering device is provided close to the load end or power end of the linear motion component to absorb impact loads, thereby reducing the stress on screws and nuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If buffering devices are added to reduce impact loads on screws and nuts, then service life is improved, but device complexity increases
Solution Approach 1:
The buffering device is nested within the existing cylinder barrel structure, with buffer components positioned inside the cylinder barrel near the piston rod connection points. This nesting approach allows the buffering function to be integrated into the existing structure without adding external components, thereby improving service life while minimizing increases in device complexity
Solution Approach 2:
The buffering device acts as an intermediary element between the piston rod and the load, absorbing impact loads before they reach the screws and nuts. This intermediary buffering component protects the critical fastening elements, extending their service life while maintaining a relatively simple overall device structure
2Ease of operation
If single-stage electric cylinders are used to meet installation space requirements, then ease of operation is improved, but adaptability deteriorates
Solution Approach 1:
The electric cylinder is divided into functional segments including the cylinder barrel, piston rod, and buffering device sections. This segmentation allows the single-stage cylinder to be optimized for compact installation while the buffering segments provide additional functional adaptability for different application requirements, resolving the contradiction between ease of operation and adaptability
