1. Product Description and Features

The KH and KF Series Hypoid Helical Bevel Gearboxes by APEX Dynamics, Inc. feature an innovative hypoid helical bevel gear design optimized for inertia moment, delivering high positioning accuracy, efficiency, and low noise operation. They offer long service life and flexible mounting options with multiple output shaft types (smooth, keyed, DIN 5480 spline, hollow shaft). The output shaft rotates in the same direction as the servo motor, simplifying machine control.

2. Ordering Information

Ordering codes specify gearbox type (KH or KF), gear size, output shaft type (S1-S4), and motor manufacturer/model. Reduction ratios include 1-stage (3, 4, 5, 7, 10) and 2-stage (12 to 100). Example: KF100-010 SIEMENS 1FT6 041-4AF71-S1.

3. Performance Specifications

4. Mechanical and Dimensional Data

Detailed dimensions for KH models (064 to 285) include shaft diameters, flange sizes, bolt patterns, and mounting angles. Permitted radial and axial loads depend on output speed and shaft position. Inertia values for input shafts are tabulated by model and shaft diameter. Load calculation formula: M2k = F2a × Y + F2r × (X + Z2), where forces and distances are model-specific.

5. Operational Guidelines and Recommendations

• Backlash measured at 2% nominal torque ensures precision.
• Respect radial and axial load limits to maintain gearbox integrity.
• Use synthetic grease lubrication for all conditions.
• Mounting allowed in all directions for flexible integration.
• Noise may increase by 3–5 dB at lower ratios or higher RPMs.
• IP65 rating ensures dust and water resistance.

7. Selection Procedure for Optimum Gearbox

1. Identify operation type: continuous (S1) or cyclic (S5).
2. Calculate gear ratio using provided formulas.
3. Evaluate duty cycle and work time.
4. Calculate mean output torque and max acceleration torque.
5. Select gearbox size based on torque limits; choose larger size if exceeded.
6. Verify mean output speed against nominal speed.
7. Calculate radial and axial loads; compare with permitted values.
8. Adjust gear ratio or motor size if necessary.
9. Choose backlash and shaft options before ordering.

8. Glossary and Definitions

• Nominal Input Speed (n1N): Continuous operation input speed limit.
• Max Input Speed (n1B): Absolute max input speed under cyclic operation.
• Backlash: Angular play between gear teeth, measured in arcminutes.
• Torsional Rigidity: Torque to rotate output shaft by 1 arcmin.
• Moment of Inertia (J1): Resistance to rotational speed change.
• Breakaway Torque: Torque to initiate rotation at input.
• Back Driving Torque: Torque to initiate rotation at output.
• Running Noise: Operational noise level influenced by speed and ratio.
• Degree of Protection (IP65): Dust and water ingress protection standard.

9. Critical Parameters and Limitations

• Max input speeds vary by model (2,200–6,500 rpm).
• Do not exceed max radial and axial loads to prevent damage.
• Operating temperature limits must be respected for lubrication and performance.
• Noise levels may increase under certain conditions.

10. Torque Measurement Procedure

Torque and torsion angle measurement involves gradually releasing applied torque while recording values to form a closed hysteresis curve. This curve is essential for understanding gearbox mechanical behavior under load.

11. Visual Aids and Diagrams

Included diagrams illustrate backlash measurement, torsional rigidity hysteresis curves, and load directions on the output shaft, aiding comprehension of mechanical properties and measurement methods.
