ROTARY ELECTRIC MACHINE AND O-RING FOR ROTARY ELECTRIC MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039360 titled 'ROTARY ELECTRIC MACHINE AND O-RING FOR ROTARY ELECTRIC MACHINE

Simplified Explanation

The abstract describes a rotary electric machine that includes a housing with an internal cavity housing a rotor/stator assembly. The rotor is positioned on a main shaft of the machine. The machine also includes a lubricating fluid reservoir with a hub portion defining an inner surface, and at least one roller bearing coupled to the main shaft and supported by the hub portion and a bushing. An oil ring is fastened to the bushing and arranged between the main shaft and the inner surface of the hub portion. The oil ring has a wall with a circular cross section and at least one elongate and inclined projection on its outer surface. The rotation of the oil ring generates a pressure difference between the lower and upper edges of the projections, forcing the lubricant towards the roller bearing.

• The invention is a rotary electric machine with an improved lubrication system.
• The machine includes a housing, rotor/stator assembly, lubricating fluid reservoir, roller bearing, bushing, and oil ring.
• The rotor is positioned on a main shaft of the machine.
• The lubricating fluid reservoir defines a hub portion with an inner surface.
• The roller bearing is coupled to the main shaft and supported by the hub portion and a bushing.
• The oil ring is fastened to the bushing and arranged between the main shaft and the inner surface of the hub portion.
• The oil ring has a wall with a circular cross section and elongate and inclined projections on its outer surface.
• The rotation of the oil ring creates a pressure difference between the lower and upper edges of the projections, pushing the lubricant towards the roller bearing.

Potential applications of this technology:

• Electric motors and generators
• Automotive industry
• Industrial machinery

Problems solved by this technology:

• Improved lubrication system for rotary electric machines
• Ensures proper lubrication of roller bearings
• Reduces friction and wear

Benefits of this technology:

• Enhanced performance and efficiency of rotary electric machines
• Extended lifespan of roller bearings
• Reduced maintenance and downtime due to improved lubrication

Original Abstract Submitted

a rotary electric machine is provided that includes a housing that forms an internal cavity that houses a rotor/stator assembly, in which the rotor is positioned on a main shaft of the machine, a lubricating fluid reservoir defining a hub portion defining an inner surface, and at least one roller bearing coupled to the main shaft and supported by the hub portion and by a bushing. the machine includes an oil ring fastened to the bushing and arranged between the main shaft of the machine and the inner surface of the hub portion, wherein the oil ring includes a wall having a substantially circular cross section and at least one elongate and inclined projection on an outer surface of the wall, each elongate and inclined projection having a lower edge and an upper edge and in which the rotation of the oil ring generates a pressure difference between the lower edge and the upper edge to force the lubricant towards the at least one roller bearing.
