Overheating of chain compost turning machine bearings is a common problem in fermentation equipment, mainly caused by factors such as lubrication, sealing, load, installation, and environment.
Firstly, poor or improper lubrication. Insufficient lubricating oil will lead to dry friction in the bearings, while excessive lubricating oil will hinder internal heat dissipation, both of which can easily cause a rapid temperature rise. After long-term use, deteriorated lubricating oil containing impurities will lose its lubricating and protective function, directly causing the bearings to overheat.
Secondly, damaged seals allow dust and moisture to intrude. Compost turners operate in a high-humidity, dusty, and corrosive manure fermentation environment. Wear or aging of the seals allows moisture, manure dust, and corrosive substances to enter the bearings, wearing down the raceways and balls, increasing frictional resistance, causing overheating, and even abnormal noise and seizure.
Thirdly, excessive load and continuous overload operation. Excessively wet or sticky materials, or overfilling of the fermentation tank, will significantly increase the turning resistance, causing the bearings to bear heavy loads for extended periods, exacerbating frictional heat generation. Meanwhile, prolonged continuous operation of the equipment can also lead to persistently high temperatures due to the inability to dissipate heat effectively.
Finally, poor heat dissipation and component wear can also contribute to overheating. High ambient temperatures and inadequate ventilation result in slow heat dissipation from the bearings themselves; worn or aged bearings with abnormal clearances can also generate significant heat during operation. Regularly checking seals, ensuring proper lubrication, and controlling the load can effectively prevent bearing overheating failures.
