The core advantages of using gray cast iron for the ZQ soft tooth surface reducer box are as follows:
1. Excellent shock and noise reduction performance
Gray cast iron contains flake graphite, which can absorb gear meshing vibration and operating noise. It is suitable for low-speed and heavy-load transmission with soft tooth surfaces, making the operation smoother and reducing gear impact wear.
2. Rigid enough and not easily deformed
The structure is dense and the compressive stiffness is high, which can firmly fix the bearing seat, ensure the coaxiality of the shaft system, and prevent the deformation of the box from causing gear eccentric loading, jamming, and oil leakage.
3. Excellent casting performance
It has good fluidity and small shrinkage, and can easily cast the complex inner cavity, ribs, oil tank, and mounting base of the reducer with complete molding and few pores and blisters, making it suitable for mass production.
4. Good cutting processability
The hardness is moderate, the bearing hole, joint surface, and mounting surface are easy to finish, the accuracy is easy to meet the standard, and the assembly sealing is good, effectively preventing oil leakage.
5. High dimensional stability
After aging treatment, the residual stress is small, it is not easy to deform during long-term continuous operation, and the accuracy remains good for long-term use.
6. Excellent heat dissipation effect
Thermal conductivity is better than ordinary steel, and it can quickly dissipate the heat generated by gear meshing and bearing operation, reducing the temperature rise of the entire machine.
7. Oil-resistant and aging-resistant
It has good compatibility with industrial gear oil, is not easily corroded by oil, and has a stable structure when immersed in oil for a long time.
8. The most cost-effective
The raw materials are easy to obtain, the casting and processing costs are low, and the cost of the box is lower than that of ductile iron, cast steel, and welded boxes, and it fully meets the needs of soft tooth surfaces under normal working conditions.
9. Strong pressure bearing capacity
It can withstand radial loads and is not prone to cracking due to installation pressure. It is suitable for general industrial loads such as conveyors, mixers, and winches.
