The hardness selection of elevator shock absorber rubber is crucial, as it directly affects the shock absorption effect and load-bearing capacity
The following are common hardness ranges and their applicable scenarios:
Low hardness (Shore A 30-50): This very soft rubber provides excellent shock absorption and noise control, suitable for precision equipment that is highly sensitive to vibration or environments that require quietness
Medium hardness (Shore A 50-70): This is the most commonly used range, achieving a good balance between shock absorption and load-bearing capacity, making it a reliable choice for general industrial machinery and many medium-sized equipment such as elevators
High hardness (Shore A 70-80): With a hard texture, it provides extremely high load capacity and mechanical stability, mainly used in situations where it needs to withstand huge static loads or suppress structural sound transmission
Factors to Consider When Choosing Hardness
When selecting the hardness of rubber shock absorbers for elevators, the following key factors need to be considered comprehensively
Application scenario: As a system that carries passengers and equipment, elevators usually need to be selected within a medium hardness range to ensure effective shock absorption and stable support.
Load bearing requirement: The higher the hardness, the stronger the load-bearing capacity, but excessive hardness may affect the shock absorption effect, so it is necessary to find a balance point
Environmental conditions: Temperature can affect the hardness of rubber. High temperatures may cause rubber to soften, while low temperatures may cause it to harden and become brittle. Therefore, when selecting, it is necessary to reserve a certain hardness margin to adapt to environmental changes
summary
In short, in the context of elevator rubber shock absorbers, the more accurate expression of “rubber dryness” is “rubber hardness”. Choosing the appropriate Shore A hardness (usually between 30-80) is a key step in ensuring smooth, quiet, and safe elevator operation
