Consider the following when designing or servicing your gear units

By SEW Eurodrive.

A gear unit is required to convert the torque and speed of an upstream electric motor so that they meet the technical drive requirements of an application. For that reason, the gear unit is the central component of a gearmotor. SEW Eurodrive gear units can be used flexibly. Be it for a specific customer solution or a standard application. Select your gear unit from a wide assortment. The right size, power, gear ratio, the right torque as well as design and surface. Tailored to your application requirements and to your area of application.

• Mounting Position: The orientation of the gear unit determines the amount of oil. M1 contains the least; M2 and M4 contain the most. Whenever possible, design your system for M1.
• Input Speed: The faster the oil churns, the higher the churning losses. Therefore, a gear unit with 4-pole motor (~1475 rpm) will run cooler than with a 2-pole motor (~2800 rpm).
• Synthetic Oil: Synthetic oil is known to reduce friction by 25%, which can be significantly on worm gear units or large gear units. Synthetic oil allows the gear unit to run cooler, doubling the oil service life, which reduces your maintenance interval and costs.
• Viscosity: The “thicker” the oil, the more resistance it has to flow and the more energy it requires moving. Always use the correct viscosity, considering the type of application and ambient temperature.
