The core components of the ZLY630-8-I gear reducer mainly include gears and bearings, whose service life is affected by many factors, as follows:
Gear life : ZLY630-8-I gear reducer gears are usually made of high-quality alloy steel through carburizing and quenching, and the tooth surface hardness reaches HRC54-62. Under normal working conditions, that is, the load does not exceed the rated torque, the lubrication is good, the ambient temperature is suitable, etc., the gear life can generally reach more than 10 years. If the actual load exceeds the rated torque, the gear life will be shortened sharply. For example, when the load factor reaches 1.2 (safety factor ≈ 0.83), the gear life may be reduced to 1/5 of the theoretical value.
Bearing life : The life of a bearing is usually expressed as L10 life, which is the operating time for 90% of the bearings to operate without fatigue failure under rated load. The L10 life of ZLY630-8-I gear reducer bearings is generally more than 15,000 hours. If the actual load exceeds the rated load, the life needs to be corrected using the formula: actual life = L10 life × (rated load/actual load)⊃3;. In addition, bearing life is also closely related to factors such as lubrication conditions, installation accuracy, and environmental conditions. If lubrication is poor, installation accuracy is poor, or the environment is harsh, the bearing life may be significantly shortened.
