LOAD CALCULATIONS Belt Driven Application Analysis

Belt and Sheave Manufacturers and their distributors typically provide a Load Analysis Data Output Sheet to the end user/OEM as a technical service. When requesting a quotation, Wolong America suggests the Load Analysis Data Output Sheet be provided in addition to this form for a complete motor shaft and bearing analysis.

End User: Application information (e.g. fan, pump, crusher): Type of Driven Load (e.g. variable torque, constant torque, constant horsepower): Motor Rating - Required Horsepower: Frame Size: Motor Enclosure: Voltage: Shaft Orientation (e.g. horizontal, vertical shaft up, vertical shaft down): Belt information - Required Distance between face of motor endshield and center line of motor sheave width (L): Inertia of driven load referred to the motor shaft (lb-ft 2 ) (required for centrifuge): The following is not required when a Load Analysis Data Output sheet is provided: Option A
