alpha Value Line - NPT

Product catalog summary
Overview: The document provides technical specifications and sizing data for the alpha Value Line series of gearheads, specifically the NPT model. These gearheads are noted for their efficiency, flexibility, and reliability, making them suitable for applications such as high-precision axes in machine tools and packaging machinery.
Specifications: The alpha Value Line offers gear ratios ranging from 3 to 100, with a torsional backlash of ≤ 8 arcmin. Output types include smooth and grooved output shafts, with options for involute toothing and output flanges. Designed for high axial and radial forces, these gearheads support continuous and cyclic operations and offer high torque versions and food-grade lubrication.
Technical Data: The series supports a maximum torque of 800 Nm (7100 in.lb), a maximum input speed of 10000 rpm, and an efficiency of 97%. The maximum radial force varies, with the highest being 9900 N (2200 lbf). The gearheads are painted in pearl dark grey and innovation blue, with a protection class of IP 64.
Sizing Procedure: A simplified sizing process for servo motors is outlined, based on maximum motor torque. It includes steps to determine maximum application torque, operating mode factor, and sizing factor, ensuring compatibility by comparing equivalent application torque with maximum gearhead torque.
Application and Usage: Suitable for packaging machines, tool changers, linear modules, and SCARA robots, the document provides guidelines for selecting the appropriate gearhead using the cymex® software based on application-specific requirements.
Additional Considerations: Instructions are provided for accounting for radial and axial forces at the output, determining the maximum equivalent force, and details on maximum permitted housing temperature, ambient temperature range, and lubrication specifications.
Ordering Information: The document includes technical specifications and ordering information for the WITTENSTEIN alpha Value Line gearheads, specifically the NPT series from NPT 005 to NPT 045. It details size stages, ratios, clamping hub diameters, and order codes.
Specifications:
  • Size Stages and Ratios: Available in 1-stage and 2-stage configurations with varying ratios, such as 1-stage ratios of 4, 5, 7, 8, 10 and 2-stage ratios up to 100 for the NPT 005.
  • Clamping Hub Diameters: Diameters vary by model and stage, with options from 8 mm to 38 mm.
Order Codes:
  • Gearhead Type: NPT 005 to NPT 045.
  • Output Shape: 0 = flange.
  • Number of Stages: 1 = 1-stage, 2 = 2-stage.
  • Gearhead Model: F = Standard, A = HIGH TORQUE.
  • Gearhead Variation: M = Motor attachment gearhead.
Additional Information:
  • Intermediate diameters are possible with a bushing of at least 1 mm thickness.
  • Full motor designation is required for determining attached gearhead components.
