1. How do I choose the right WP Series reducer for my application?
Start by identifying your torque requirement (up to 500 Nm), reduction ratio (5:1-100:1), and mounting style (foot/flange/shaft). Consider environmental factors: IP65 seals protect against dust/water, while cast iron housing suits high-temperature or corrosive settings. For vertical/horizontal setups, our 90° right-angle design optimizes space - share your CAD drawings for custom mounting brackets!
2. Does the WP Series support self-locking?
Yes! The worm gear's geometry prevents backdriving at ratios ≥10:1, ideal for lifts, conveyors, or static loads. Note: Self-locking is torque-dependent - consult our engineers for high-load scenarios.
3. How do I install the reducer?
Ensure alignment with the motor/output shaft (≤0.05mm ). For hollow-shaft models, use the supplied key and clamping collar. Avoid over-tightening mounting bolts - torque specs are listed in the manual. Pro tip: Run it idle for 30 minutes post-install to check for noise/vibration.
4. What maintenance does it require?
Lubrication is key! Use EP150-220 gear oil (replace every 2,000 hours or annually). Check seals for leaks and housing temperature (≤80°C during operation). No greasing needed - the bath-lubricated design minimizes downtime.
5. Can I customize the output shaft or housing?
Absolutely! Choose solid/hollow shafts (metric/SAE), flange sizes, or add B5/B14 motor adapters. We offer custom paint (RAL colors), galvanization, and even flange drilling patterns - lead time is 2-4 weeks for bespoke orders.
6. Why is the noise level higher than helical reducers?
Worm gears inherently produce more noise (75-85 dB) due to sliding contact. For quiet operation (≤70 dB), opt for our WP-Silent variant with precision-ground gears - ideal for food packaging or medical equipment.
7. What's the warranty?
2 years for defects in materials/workmanship, excluding wear parts (seals, oil). Register your product online for extended coverage.
8. Can it run continuously at 100% load?
Yes, but monitor temperature! The cast iron housing dissipates heat efficiently, but ambient temps >40°C may require a cooling fan (available as an accessory).
9. How to troubleshoot overheating?
First, check oil level (1/3-1/2 housing height). If oil is black/gritty, replace it. Ensure proper ventilation - blocked cooling fins raise temps. Still hot? Contact us - we'll audit your load calculations.
