Technical Specifications

The K Series Helical-Bevel Gear Motor is the ultimate solution for applications requiring high torque, durability, and a space-saving right-angle output. Combining high-quality helical gears with a robust bevel gear stage, this series delivers exceptional performance and reliability even in the most demanding industrial environments. Its high efficiency and low-backlash operation make it a superior choice for a wide range of drive tasks.

Quick Overview: High torque right-angle drive with strong durability, compact footprint, and stable performance.

High Torque Right-Angle Output High Efficiency Low Backlash

Key Features

  • High Torque & Load Capacity: Robust bevel gear stage supports high torque and significant overhung load capacity.
  • Space-Saving Right-Angle Output: 90-degree output is ideal for conserving space and simplifying machine layouts.
  • Exceptional Efficiency: High-quality, case-hardened helical and bevel gears minimize power loss across the ratio range.
  • Durable & Low-Maintenance: Designed for long service life with minimal maintenance requirements.
  • Low Rotational Backlash: Precision gearing provides low backlash for accurate positioning applications.

Design and Mounting Options

The K Series is engineered for maximum flexibility with a wide array of versions:

  • K..: Foot-mounted with solid shaft.
  • KA..: Hollow shaft mounted.
  • KF..: B5 flange-mounted with solid shaft.
  • KAF..: B5 flange-mounted with hollow shaft.
  • KH..: Hollow shaft with shrink disk for a secure, backlash-free connection.
  • KV..: Splined hollow shaft (to DIN 5480).
  • KAZ.., KVZ.., KHZ..: B14 flange-mounted versions with hollow, splined, or shrink disk shafts.

Engineering Data and Selection Verification

Use the information on this K Series Transmission Industrial Helical Gearbox With Motor 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.
