Sand Casting Gearbox Housing Reduce Internal Friction

Gearbox housing is a device used to install the housing structure of the transmission mechanism and its accessories. It can be manufactured by CNC engraving, sand casting, transparent acrylic(PMMA/PC) 3D Printing. Structural characteristics The simple transmission has the advantages of high efficiency, simple structure and convenient use, but the number of gears is small, the range of change is small (traction, speed range is small), and it should only be used in some turns with a small number of gears. If the range of i is increased, the transmission size is increased, the shaft span is increased, in order to increase the number of gears without making the shaft span too large, the component transmission can be used. The so-called component transmission is usually a combination of two simple transmissions, the one with more gears is called the main transmission, and the one with less is called the auxiliary transmission.
