Knurled pinnau yn dylunio i darparu a cryf gafael yn a eang ystod o deunyddiau. Maent nodwedd cyfres o esgyll neu grooves o gwmpas y cylchedd y pin, sydd cynnydd arwyneb ardal pin yn cyswllt gyda deunydd. Mae hyn yn darparu cwmni hold, ataliol y pin o llithro neu nyddu cynulliad. Knurled pinnau yn yn yn nodweddiadol o ddeunyddiau fel dur, neu alwminiwm.
Spring pins, on the other hand, are designed to provide a secure, self-retaining fit in mechanical assemblies. They are also known as roll pins or split pins, and are made from materials such as stainless steel or carbon steel. A spring pin consists of a cylindrical body with one or more notches cut into it, which allow the pin to be compressed during insertion and then expand to hold the assembly together. This gives them a high level of resistance to vibrations, and makes them ideal for use in applications where parts need to be securely fastened together.
In summary, while both knurled pins and spring pins are important components in mechanical assemblies, they serve different purposes. Knurled pins are designed to provide a firm hold, while spring pins are designed to provide a secure, self-retaining fit. Understanding the differences between the two can help engineers and designers select the right fastener for their specific application.
