[Gear] Construction Machinery Failure Prevention Measures
1, to improve mounting precision gear
2, a reasonable selection
Select the gear material, according to the strength, toughness and process performance requirements, considering. Combined with China's reality, should use low-carbon alloy carburizing steel. For under heavy load and shock load gear used in Ni-Cr and Ni-Co-Mo alloy carburizing steel-based steel; the load is relatively stable or less power, small modulus gear, can also be used without Ni, Ni-Mn steel. Compared with this steel manufacturing gears and gear ordinary electric furnace steel manufacturing, the contact and bending fatigue life can be increased 3-5 times, gear limit load can be increased by 15% -20%.
3, heat treatment
By heat treatment process can be improved gear materials, an appropriate increase in hardness, slashing or reducing local overload of the tooth surface to improve the ability of stripping out the tooth surface. Examples of coal mine machinery gears, deep carburizing, hardening gear can be reduced to improve the core hardness, the smaller the residual tensile stress enough the transition zone and petrochemical depth.
4, according to the actual situation to select the gear oil
According to statistics, 34.4% mechanical failure stems from lack of lubrication, improper lubrication from 19.6%, in other words, 54% of mechanical failures are due to lubrication problems caused. Therefore, the choice of gear to improve the life of the importance of good gear oil.
