Two machining schemes commonly used in gear forming method include gear milling and gear grinding. These two schemes have their own characteristics, and the processing of different types of gears is analyzed in detail. 1) Gear milling Gear milling refers to the processing technology of milling one tooth slot...
Large gears generally refer to gears with gear modulus > 16 mm, which are widely used in heavy machinery such as engineering machinery, mining, metallurgy and so on. There are many kinds of large gears, such as spur gear, arc gear, bevel gear, etc. At present, there are two...
① According to the causes of cracks, the process flow of gears was analyzed again. It was found that there was no preliminary heat treatment before heat treatment, and there was no aging process after semi precision grinding after heat treatment. Now, the process flow of this type of...
