The structure of the assembly line roller sprocket
The sprocket tooth profile must ensure that the chain can enter and exit the mesh smoothly and freely, minimize the impact and contact stress of the chain link during meshing, and be easy to process.
What are the parameters of the skateboard wheel
Skateboard wheels are usually made of polyurethane as the main material. The proportion of polyurethane in the wheel is different, and the hardness of the wheel is also different.
duplxe roller chain wheel sprocket tells: the necessity and principle of sprockets quenching!
Sprockets quenching means that some parts (including sprockets) are subjected to alternating loads and impact loads such as torsion and bending during work, and its surface layer bears higher stress than the core.
duplxe roller chain wheel sprocket tells: What is the reason for the cracks in the sprocket?
Sprocket cracks and cracks are caused by one or more reasons, such as improper grinding, improper heat treatment, excessive stress or material defects. Cracks and cracks can appear on the gear.
The customized duplxe roller chain wheel sprocket teaches you how to test the tooth thickness of Sprockets?
The use of vernier tooth thickness calipers to measure tooth thickness has the advantage of convenient and simple use. The disadvantage is that the result of the measurement is affected by the diameter tolerance of the tooth tip circle (tooth tip tolerance-generally h9), and the face tooth tip is useless during the use of the gear.
The customized duplxe roller chain wheel sprocket tells the relevant knowledge of Sprockets heat treatment distortion!
The change in the volume and shape of the workpiece during the quenching process is due to the volume expansion and contraction caused by the specific volume change during the structural transformation of the steel, and the plastic distortion caused by the heat treatment stress. Obviously, the specific volume change during the phase change in the heat-treated steel must exist.
