Harmonic roller touch harmonic reducer SHG-45-160-2SO

For boiler with different parameters, the type of head is different. Low pressure boilers often use flat head or oval head; Shg-45-160-2so medium pressure boiler, generally using elliptical head; High pressure and pressure boiler, use hemispherical head. The manufacturing process of the head generally includes the following steps.



Mould cost is low, suitable for single small batch production. Spinning molding only needs a few sets of simple drum die and flanging inside roller, can spin a variety of size specifications of the head, so the mold cost is low, and flexibility. Batch production can use stamping method; The second is the size problem, the spinning method is more reasonable for the thin-walled large-diameter head of harmonic wheel touching shG-45-160-2SO, and the stamping method is more suitable for the thick-walled small-diameter head.









On the other hand, because the drum is made of several tube segments and two heads, the total length of the drum made by the harmonic wheel reducer SHG-45-160-2SO often deviates from the size specified on the drawing. According to the experience of production practice, when the circular seam adopts automatic submerged arc welding, the total length of the drum is generally slightly longer than the specified size
