Knurled shafts are standard parts in industrial manufacturing that transfer power or carry loads in mechanical equipment. It is usually made of metal, has an axial cylindrical shape, and the surface has been machined to form a specific pattern or bump. These patterns are generally distributed along the shaft length in a spiral or other geometric shape. One of the primary roles of the knurled shaft is to increase friction, thereby providing a better transmission effect or increasing its carrying capacity.
Knurled shafts are usually used in transmission systems, such as mechanical devices, and can work with other parts (such as gears, belts, etc.) to achieve power transmission. In addition, the pattern design of the knurled shaft may also be designed to provide better lubrication, such as increasing the surface area during the flow of lubricating oil on the shaft, thus improving the lubrication performance.
The design and manufacture of the knurled shaft need to consider the working conditions, the required transmission effect, and the bearing requirements to ensure that it can operate stably and reliably in practical applications.
