sprocket excavator

Final Drive & Swing Components for excavator: Planetary volvo excavator sprocket must withstand the high forces of torque generated by the engine and transfer these loads to move the equipment. All volvo excavator sprocket and final drive gears are manufactured to precise tolerances for reliable operation. The manufacturing method includes a heat treatment process that increases bending strength, prevents case crushing and provides exceptional wear resistancefor a long service life.

The pc200 sprocket wheel, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc.   The pc200 sprocket wheel is made by casting, machining, heat treatment, painting etc.The pc200 sprocket wheel is made by casting, machining, heat treatment, painting etc.   The quality and working life depends on the quality of casting steel, the hardness of rail surface, the depth of hardness layer etc. The shape of the sprocket pc200 is toothed. When the excavator digs the ground, the stress of the traveling device is relatively large. In addition to the pressure caused by the rotation and twisting of the car body, the toothed sprocket pc200 is in the front, which can play a relatively stable mobility.

1.Castings processing must produce according to requirements and drawings of excavator sprocket.  2.The workpiece is annealed to eliminate internal stress , the surface sand should be clean .Tooth relative to the standard , the error should be controlled within 5 range .  3.The modulation of heat treatment hrc30-36 , surface frequency quenching , tempering thesurface hardness of hrc48-hrc54 , hardened layer 5-9mm , core hardness of HRC28 ormore , hardened layer microstructureRequired to achieve the m4-6 stages .  4.The mechanical tensile strength & N / mm2 > 620 , yield strength & N / mm2 > 375.

According to the size of the model and the usability of the industry and mine, the mini excavator sprockets can be made of materials: G33MnCrMo, G33Mn4, SCMnCr4B, ZG35Mn, etc. After the normalizing heat treatment of the excavator sprocket blank, the matrix hardness reaches above HB235, and the driving tooth is hardened by medium frequency induction hardening and tempering at low temperature. The surface hardness reaches HRC48-54, and the hardening depth is above 5-10mm (HRC45). It can accurately transmit power under harsh working conditions, and has excellent anti-wear performance, which significantly improves product life and reduces customer use costs.
