Product catalog summary
Overview: This document provides technical specifications for a single-stage worm gear designed for use with motors. It features a special design as a free-standing gear unit with a ball-bearing ingoing shaft and lifetime grease lubrication.
Housing: The gear housing is made of massive aluminum, allowing for mounting from all accessible sides.
Output: The gear offers a power deviation of 90° with the possibility of a second shaft end. It is self-locking with a significant gear reduction of less than 50%.
Options: Available options include a special shaft and a second shaft end.
Loading Capacity: The maximum radial force is 300 N, and the maximum axial force is 150 N.
Performance: The maximum input speed is 4500 rpm, and the operational temperature range is from -20°C to +40°C.
Mounting: The standard mounting type is foot, with a shaft diameter of 12 mm. The unit weighs 0.82 kg.
Gear Ratios and Torque: The document lists various gear ratios with corresponding torque (M) and efficiency (η) values:
  • Ratio 5: Torque 15.3 Nm, Efficiency 0.78
  • Ratio 7.25: Torque 14.7 Nm, Efficiency 0.71
  • Ratio 10: Torque 16 Nm, Efficiency 0.66
  • Ratio 15: Torque 15.3 Nm, Efficiency 0.57
  • Ratio 20: Torque 14.8 Nm, Efficiency 0.51
  • Ratio 30: Torque 15 Nm, Efficiency 0.40
  • Ratio 50: Torque 12.5 Nm, Efficiency 0.28
  • Ratio 90: Torque 9.1 Nm, Efficiency 0.18
Dimensions: Specific dimensions are not provided in the document.
