Big gear is an important part of the transmission device, due to constantly interlocking with the pinion gear drive the entire operation of the equipment, the gears are more wear and tear. Therefore, the equipment manufacturing for the wear resistance of gears, load-bearing, life, heat, weight and size have a relatively high demand, which requires large gear casting and processing technology more advanced.

In the actual production, the quality requirements of large gears is very strict, so the gear processing technology is very critical, the following to introduce the big gear casting and processing technology.

Casting process

According to the customer's request, the Great Wall Casting selects the suitable wood mold to carry on the modeling design, before pouring uses the Chinese casting CAE simulation pouring,According to the following process casting：

Wood Molding - Molding - Casting - Insulation - Sand Cleaning - Heat Treatment - Roughing Plus - Packaging Shipping.

Big gear machining process is the first tooth into the mechanical processing, this time for the next step is to prepare the basis for tooth shape, so that the internal gear and the end of the hole accuracy of the basic requirements to meet the technical requirements.
