Technical Specifications

The S Series gear motor ingeniously combines the high efficiency of helical gears with the large gear ratios and right-angle output of worm gears. This design not only saves space but also ensures smooth, low-noise operation, making it a cost-effective choice for numerous applications requiring high reduction ratios and 90-degree power transmission.

Quick Overview: High reduction ratios, 90° output, smooth and quiet operation, and reliable self-locking under specific conditions.

High Reduction Right-Angle Output Low Noise Cost-Effective Self-Locking

Key Features

  • High Reduction Ratio: Two-stage transmission combining helical and worm gears easily achieves very large gear ratios.
  • Right-Angle Output: 90-degree output shaft is ideal for space-constrained installations and cleaner machine layouts.
  • Smooth & Low-Noise Operation: Worm gear characteristics help ensure low vibration and low noise in sensitive environments.
  • Cost-Effective: High reduction performance with strong cost-performance balance for practical, economical solutions.
  • Self-Locking Capability: Under specific ratios and operating conditions, helps prevent back-driving and enhances safety.

Design and Mounting Options

The S Series is available in multiple design versions to meet various installation needs:

  • S..D..: Foot-mounted with solid shaft.
  • SA..D..: Hollow shaft mounted.
  • SF..D..: B5 flange-mounted with solid shaft.
  • SAF..D..: B5 flange-mounted with hollow shaft.

Engineering Data and Selection Verification

Use the information on this S Series Industrial Helical Worm Gearbox Helical Gear Reduce page for preliminary comparison. Final dimensions, materials, interfaces and operating limits must be confirmed against the current manufacturer catalog or an approved project drawing before purchase, fabrication or installation.

Table scope: each parameter row applies only to the model or size identified in that row. Do not interpolate, combine or transfer values between sizes without manufacturer confirmation.

Required Project Inputs

  • Input speed and motor information
  • Required output speed or target ratio
  • Driven load type, start-stop pattern and operating schedule
  • Mounting position, shaft direction and available installation space
  • Site environment and maintenance-access requirements

Interfaces to Confirm

  • Model size and mounting-hole pattern
  • Input and output shaft or bore dimensions
  • Flange, keyway, coupling and guarding arrangement
  • Shaft center position and surrounding clearance
  • Lubrication and inspection access

Reproducible Speed and Ratio Check

Required ratio: input speed ÷ target output speed. Expected output speed: input speed ÷ selected ratio. Record the source of each input value and use consistent units.

This arithmetic check does not confirm torque, power, service factor, temperature, efficiency or life. Ask ZPGear to verify those items from the current manufacturer data for the selected model and operating condition.

Source record: keep the manufacturer name, catalog or drawing number, revision date, selected model size, project inputs and final approval sheet with the order documentation. Send the project information to ZPGear for confirmation.
