AI Technical Summary

Technical Problem

Existing splash lubrication gearboxes have shortcomings in lubrication and heat dissipation, especially in electrified systems where increasing the amount of lubricant can lead to mechanical power loss and increased fluid temperature. Traditional designs struggle to effectively control the distribution of lubricant and the heat dissipation effect.

Method used

It adopts a combined structure of curved shield, side oil collector and oil reservoir, and forms a high thermal conductivity material through additive manufacturing. It is designed with multiple cavities and metering orifices to control the distribution of lubricating fluid and heat dissipation path, thereby reducing mechanical power loss.

Benefits of technology

It achieves adequate lubrication and heat dissipation with a smaller thermal mass, reduces mechanical power loss, extends lubricant life, maintains fluid temperature within a reasonable range, and improves gearbox efficiency and service life.

Abstract

The utility model relates to equipment for a gear box. The equipment is used for lubricating the gear box. In one example, an apparatus includes a curved shroud surrounding a portion of a gear, a first side oil trap and a second side oil trap, an oil reservoir having a first end fluidly coupled to the first side oil trap and a second end fluidly coupled to the second side oil trap, and a metering orifice fluidly coupling the oil reservoir to the curved shroud. The oil reservoir also includes at least two U-turns between the first end and the second end, and a wall of the oil reservoir having a plurality of cavities.
