Project Overview: Compact Reducer Solution for Dutch Packaging Equipment
A Dutch customer approached us with a specific challenge for their packaging machinery application. Due to the compact nature of their equipment, they needed a space-efficient solution combining a KKM helical hypoid gear reducer with a 750W motor. The critical performance requirement was achieving an output torque of 230NM while maintaining the small footprint essential for their packaging line operations.
Understanding the Technical Requirements
Core Specifications
The customer’s parameters were clear and precise:
- Reducer Type: KKM helical hypoid gear reducer
- Motor Power: 750W
- Target Output Torque: 230NM
- Application: Packaging machinery (compact installation)
- Priority: Space optimization without compromising performance
For packaging machinery applications, the helical hypoid gear design offers distinct advantages including smooth operation, reduced noise levels, and efficient power transmission—all critical factors in production environments where equipment runs continuously.
Comprehensive Model Selection Process
Available KKM Reducer Options for 750W Motors
Using the AU reducer selection catalog, we identified the complete range of KKM helical hypoid gear reducers compatible with 750W motors:
Single Stage Models:
- KKM050 – Ultra-compact option
- KKM063 – Small form factor
- KKM075 – Mid-range size
- KKM090 – Medium capacity
- KKM110 – Higher torque capability
Two-Stage Combination Models:
- KKM050+KKM110 combination
- KKM063+KKM110 combination
- Various KKM+PC reducer combinations
Performance Range Analysis
The 750W motor-reducer combinations offer impressive versatility:
- Output Speed Range: 1.6 rpm to 373.3 rpm
- Output Torque Range: 17NM to 2,283NM
- Reduction Ratio Range: 7.5:1 to 900:1
- Radial Shaft Load Capacity: Up to 6,783N
This wide performance envelope demonstrates why KKM helical hypoid gear reducers are preferred for diverse packaging machinery applications, from slow-speed wrapping systems to faster conveyor drives.
Precision Matching: Finding the Optimal Solution
Target: 230NM Output Torque
After thoroughly reviewing the reducer selection catalog, we identified that no model provides exactly 230NM output torque. However, engineering best practice calls for selecting the nearest appropriate model based on application requirements and safety considerations.
Two Optimal Candidates Identified
Option 1: KKM090 with 226NM Output Torque
- Output Torque: 226NM (slightly below target)
- Output Speed: 22.5 rpm
- Reduction Ratio: 40:1
- Motor Configuration: 6-pole, 750W (approximately 900 rpm input)
- Radial Shaft Load: 6,238N
- Safety Factor: 1.8 (robust margin)
- Model: KKM090 helical hypoid gear reducer
Option 2: KKM090 with 258NM Output Torque
- Output Torque: 258NM (12% above target)
- Output Speed: 17.5 rpm
- Reduction Ratio: 80:1
- Motor Configuration: 4-pole, 750W (approximately 1,400 rpm input)
- Radial Shaft Load: 6,783N
- Safety Factor: 1.1 (adequate margin)
- Model: KKM090 helical hypoid gear reducer
Engineering Analysis and Final Selection
Why the 226NM Configuration Won
The customer ultimately selected the KKM090 helical hypoid gear reducer with 226NM output torque for several compelling reasons:
1. Superior Safety Factor (1.8 vs 1.1) The higher safety factor provides greater reliability for continuous packaging operations, reducing the risk of premature wear or unexpected downtime—critical in production environments.
2. Higher Output Speed (22.5 rpm vs 17.5 rpm) The faster output speed better matched the customer’s packaging machinery cycle times, improving overall throughput efficiency.
3. Lower Radial Shaft Load At 6,238N versus 6,783N, the selected model places less stress on mounting structures and bearings, potentially extending service life.
4. Cost-Effective Motor Selection The 6-pole motor configuration typically offers better cost-performance balance than 4-pole alternatives in this power range.
5. Proven Performance While delivering 226NM instead of the requested 230NM, this 1.7% difference proved negligible for the application after load calculations, while the benefits clearly outweighed the minor torque reduction.
Key Advantages of KKM Helical Hypoid Gear Reducers
Why Choose KKM for Packaging Machinery?
Compact Design Philosophy The helical hypoid configuration allows for offset input and output shafts, enabling more flexible installation in tight spaces—essential for modern packaging equipment.
High Efficiency Power Transmission KKM reducers typically achieve 92-96% efficiency, minimizing energy waste and reducing operating costs over the equipment’s lifetime.
Smooth, Quiet Operation The helical gear tooth contact pattern produces less vibration and noise compared to standard spur gears—important in food packaging and pharmaceutical applications.
Robust Construction Precision-machined housings and high-grade alloy gears ensure reliable performance under continuous duty cycles typical in packaging lines.
Wide Ratio Selection With ratios from 7.5:1 to 900:1 available, KKM reducers can be matched to virtually any packaging machinery speed requirement.
Application Considerations for Packaging Machinery
Critical Factors in Reducer Selection
Duty Cycle and Load Characteristics Packaging machinery often operates 16-24 hours daily. The 1.8 safety factor in the selected model provides necessary protection against shock loads during start-stop cycles and product jams.
Environmental Conditions Consider operating temperature, potential exposure to washdown procedures, and ambient humidity when specifying sealing options and lubricant types.
Maintenance Accessibility The KKM090 footprint allows for reasonable access to mounting bolts and inspection ports even in crowded machinery layouts.
Integration Requirements Motor mounting configurations, shaft dimensions, and torque arm provisions must align with existing machinery interfaces.
