Product Details

Brief Introduction

The YKK-630-2 AC Shunt Motor integrates optimized lubrication systems for high-speed operation. Pressure-fed lubrication ensures stable oil circulation through precision pumps with filtration, ideal for heavy-duty applications. Oil-ring lubrication operates seamlessly for horizontal shafts >50mm diameter, while oil-bath systems support vertical thrust bearings. Critical design features include:

• Labyrinth seals preventing lubricant contamination

• Viscosity-adaptive oil grooves maintaining film integrity

• Temperature-controlled reservoirs for thermal management

 

This AC Shunt Motor eliminates manual greasing risks through automated mist lubrication (Method 8) at peripheries exceeding 15m/s. For moderate speeds (4-5m/s), capillary wick feeders provide consistent filtration-backed lubrication. The motor's bearing housings accommodate dual oil rings for width-diameter ratios >2, ensuring uniform oil distribution. Maintenance protocols specify:

• Annual oil analysis for pressure systems

• Quarterly wick replacement in wick-lubricated units

• Real-time viscosity monitoring

 

Engineered to prevent lubricant starvation during starts/stops, the YKK-630-2 AC motor extends bearing life versus splash-lubricated alternatives under equivalent loads. The YKK-630-2 AC motor integrates advanced lubrication systems to ensure bearing longevity under high-speed operation. Its precision-engineered oil-ring system (for shafts >50mm) delivers consistent lubricant distribution at 4-5m/s peripheral speeds, while pressurized oil circulation supports critical loads via pump-fed filtration and reuse. This AC Shunt Motor employs dual protection: oil-slinger rings maintain bath levels for vertical thrust bearings, and mist lubrication compatibility counters dust ingress in contaminated environments.
