Cam Slider Shock Absorber Press-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cam slider shock absorbing members in cam devices face issues with limited stroke, difficulty in replacement, increased space requirements, and high installation complexity due to the need for adhesive agents and multiple components.
Innovation Solution
A cam slider shock absorbing member with a mounting portion larger than the mounting hole and a deflecting portion that projects from the hole, allowing for press-fitting without adhesives, and featuring a roughened inner surface and air vent port for improved fixation and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cylindrical shock absorbing member is inserted into a mounting hole and fixed with adhesive agent, then the shock absorbing function is achieved, but the stroke cannot be set to large value and the installation process becomes complex
Solution Approach 1:
The invention extracts the adhesive agent from the fixation system and replaces it with a mechanical press-fit structure. The shock absorbing member is designed with a mounting portion having an external dimension larger than the internal dimension of the mounting hole, creating a press-fit connection that eliminates the need for adhesive agents and complex installation procedures.
Solution Approach 2:
The shock absorbing member's mounting portion is designed to self-fixate through press-fit into the mounting hole without requiring external adhesive agents. The structural design itself provides the fixation function, making the system self-sufficient and simplifying installation.
2Length of moving object
If the shock absorbing member is designed with a deflecting margin portion having a larger diameter, then the stroke can be increased, but the protruding amount from the wall surface increases and space requirement is increased
Solution Approach 1:
The invention transitions the shock absorbing member's stroke-generating structure from a radial expansion (deflecting margin portion with larger diameter) to a vertical dimension (deflecting portion with specific height). By setting the height of the deflecting portion to correspond to the required stroke length, the design achieves the necessary stroke without increasing the radial protrusion from the wall surface, thus optimizing space utilization.
3Ease of manufacture
If a through hole is provided in the shock absorbing member to allow bolt and collar insertion, then the member can be screwed into the supporting base, but the number of components increases and cost increases
Solution Approach 1:
The invention removes the bolt and collar components from the mounting system and replaces them with a press-fit structure. The shock absorbing member's mounting portion is designed with external dimensions larger than the mounting hole's internal dimensions, enabling direct press-fit installation without requiring additional fastening components, thereby reducing component count and cost.
4Ease of repair
If the shock absorbing member is designed without adhesive agent, then replacement becomes easy and installation is simplified, but the fixation strength may be compromised
Solution Approach 1:
The invention replaces the chemical bonding mechanism (adhesive agent) with a mechanical bonding mechanism (press-fit structure). The mounting portion's external dimension is designed to be larger than the mounting hole's internal dimension, creating a mechanical interference fit that provides both strong fixation and easy replacement capabilities without requiring adhesive agents.

AI summary
In order to provide a cam slider shock absorbing member for a cam device which realizes a sufficient stroke, easy replacement, a compact profile, and an easy-to-machine property without necessity of adhesive agent, the shock absorbing member includes a mounting portion having an external dimension at least larger than an internal dimension of a mounting hole on the side of a lower end thereof and a deflecting portion having a predetermined distance for a deflecting margin with respect to an inner wall surface of the mounting hole on the upper side of the mounting portion, and an upper end of the deflecting portion projects upward from an opening end of the mounting hole and being formed to have a height which secures a length corresponding to the stroke to be compressed.
