AI Technical Summary
The lubrication requirements of the gearbox bearings in high-speed electric loaders are difficult to meet. Ordinary splash lubrication methods are not feasible and may lead to high-temperature spontaneous combustion. Furthermore, gearboxes that do not use hydraulic shifting lack effective lubrication and cooling methods.
Design a lubrication and cooling system including a housing, a housing cover, a circulating pump, and an external radiator. The system uses hydraulic oil for spray lubrication and circulating cooling to achieve bidirectional lubrication and cooling of the bearing, and uses the circulating pump and radiator to reduce the temperature of the lubricating oil.
It achieves efficient bearing lubrication and cooling, has a simple structure and low cost, is suitable for high-speed electric loader gearboxes, and avoids the risk of spontaneous combustion at high temperatures.
