How to size a worm gear reducer
Power, input and output speed, service factor and required output torque.
Correct sizing considers motor power, desired speed, output load, operating hours and environment (dust, humidity, temperature). Pierini provides technical support to select reduction ratios from 1:7.5 to 1:2,500.
Preventive maintenance of reducers
Lubrication, seals and periodic inspection for longer service life.
Check oil level and quality per manual, monitor leaks and abnormal noise. Replace worn seals and keep maintenance records for critical equipment.
When to choose a custom project
Non-standard flange, shaft, ratio or housing — Pierini engineering handles it.
Custom projects are indicated when the application requires non-standard flange, extended shaft, dual output or specific motor integration. Send drawing or sample for engineering review.
Reducers in irrigation: reference and manufacturing
Difference between market models (G15/WPA) and Pierini-manufactured PR Line.
G15 and WPA are market technical references for pivot drives. Pierini manufactures the PR Line and develops special irrigation projects — contact our team for correct specification.
