1.The casing is casting steel and steel plate welding structure, the basement is steel casting, it welded with steel plate after coarsely machining, and finish machining after integral annealing for stress elimination.
2.Transmission gear is harden tooth spiral bevel gear drive, have higher loading capacity, smooth running and long service life.
3.The input shaft is alloy forging by quench hardening and tempering, has good mechanical property, fit for big torsional moment operation. chain wheel and flange can be equipped on the shaft end, meet the requirement of all transmission mode.
4. Master bushing adopt alloy casting steel, it has high rigidity and reliable performance.
