NMRV030 reducer material: RV30 reducer is not done well in processing technology and material selection, it may cause transmission failure.It is also a problem that gear reducer manufacturers may encounter when producing parts. For example, the hardness of the hard-faced reducer does not meet the requirements, and the unreasonable design of the screw elevator bearing will also cause similar problems.Due to the large meshing friction of the worm drive, the difficulty of the worm gear hob to accurately shovel the back and the shape and size error, it is difficult for the machined worm gear tooth surface to fully meet the theoretical requirement of the conjugate state with the matched worm tooth surface.Therefore, the material combination of the worm and the worm gear must have both abrasion resistance and good running-in performance.The worm material is generally made of alloy steel or high-quality carbon steel. The worm tooth surface is treated by carburizing, quenching or nitriding to obtain a higher hardness. The hardness is generally between 35---55HRC, but also 60HRC or more. of.The material used to make the worm gear ring is ideally tin bronze, and the mechanical properties of centrifugal casting are good in the processing technology, followed by casting with metal molds, instead of casting with sand molds as much as possible.
