What are the common causes of oil leakage in the lubrication system of XLD2-0.55-29 cycloidal pinwheel reducer

The common causes of oil leakage in the lubrication system of XLD2-0.55-29 cycloidal pinwheel reducer include sealing problems, improper installation and maintenance, abnormal oil volume, box problems, and harsh operating conditions, as follows:

Aging or damage of seals: After prolonged use, seals such as oil seals and bearing seals may lose their sealing properties due to wear and aging, leading to lubricant leakage. This is one of the common reasons for oil leakage in gearboxes.

Improper installation: During the installation of the reducer, if the alignment accuracy between the machine shaft and the driven device shaft is low, it will accelerate the wear of the oil seal and bearings, leading to oil leakage. In addition, incorrect installation direction of seals and failure to compact them during installation can also cause their sealing performance to fail and lead to oil leakage.

Inadequate maintenance: If the lubricating oil is not cleaned properly during replacement, impurities and metal shavings may enter the interior of the gearbox, which will accelerate the wear of the seals. In addition, incomplete removal of dirt on the joint surface during maintenance, or failure to replace aging or damaged seals in a timely manner, can also easily lead to oil leakage.

Excessive oil volume: If too much lubricating oil is added to the reducer, the oil pool will be stirred during operation, and the lubricating oil will splash everywhere in the machine. A large amount of lubricating oil will accumulate in the shaft seal, joint surface, etc., which is easy to leak out from weak seals.

Box deformation or damage: Long term use or exposure to impact, vibration, etc. of the gearbox may cause deformation of the box, resulting in uneven joint surfaces and inadequate sealing, leading to oil leakage. In addition, the inspection hole cover plate is too thin, which can cause deformation after tightening the bolts and also lead to oil leakage.

Excessive internal pressure difference: During the operation of the reducer, the friction heat generated by the moving pair will cause the internal temperature to rise. If the ventilation hole is blocked, the internal pressure will gradually increase, forming a large pressure difference with the outside world. Lubricating oil will leak out from the gaps under the pressure difference.

Poor operating environment: If the gearbox is in an environment with high temperature, high humidity, or corrosive media such as acid, alkali, salt, etc., it will accelerate the aging and damage of the seals, reduce their sealing performance, and lead to oil leakage.
