The primary condition of the precision casting gear
The primary conditions for machining gears by precision castings are analyzed as follows:
In the whole process of gear production and processing of bit water glass alloy steel castings, these excellent rough embryo forming processes, more stable and high-precision heat treatment processes, and especially suitable surface hardening procedures are all the first conditions for Z to produce gear classics later. For example, there are many important stages in grinding production and processing: only according to the use of grinding wheels with sharp grinding edges and low ground stress on the grinding surface, the grinding cutting speed can be increased and the grinding time will be reduced. it is to improve the grinding efficiency and increase the distance between grinding wheels to control the cost.
The design scheme of water glass precision steel casting 26 is not only a key factor of precision casting but also a start-stop process, which is also a key factor for gear forging, which is related to the quality and level of the cast gear. it is an indispensable stage to select more suitable forged gear raw materials, carry out excellent and effective overall design, and adopt highly efficient gears and rolling bearings.
Under the premise of ensuring that there are no grinding scald cracks and ensuring quality and quantity, it is necessary to apply as high as possible the main grinding parameters to reduce the grinding period, so as to improve the grinding efficiency and benefit. It is also necessary to ensure its precision and reduce surface roughness. According to the application of more suitable grinding oil, it can ensure that under the premise of excellent moistening and antirust treatment, it is also beneficial to reduce the ground stress on the surface of the grinding journal, prevent scald cracks, reduce the surface roughness, reduce the level of blocking the air hole of the grinding wheel, and ensure the sharpness of the grinding wheel, that is, reduce the refurbishment of the grinding wheel, reduce the use of the grinding wheel and control the cost.
