WPWV Worm Reducer — Core Features
■ WPW Universal Body + V Extended Output Shaft
Universal P-housing with V-type extended output shaft — enables multi-point loading and wider equipment spacing in any WPW input orientation.
■ V-Type Extended Shaft — Multi-Point Loading Capability
The extended output shaft allows sprockets, pulleys, and coupling hubs to be positioned at multiple points along the shaft — key for wide-span conveyor and chain drive installations.
■ Universal Input Direction — Motor Position Flexible
All WPW input directions supported with V-type extended output — motor position flexible regardless of shaft extension requirements.
■ Extended Shaft — Longer Bearing Span
Extended shaft reduces bending moment per unit load at the coupling point — beneficial for applications with significant overhung sprocket or pulley loads.
■ Output Torque to 4,440 Nm — V-Type Full Capacity
V-type extended shaft designation does not affect worm gear torque ratings.
■ One Product — All V-Type Input Configurations
Eliminates direction-specific V-type reducer variants from the BOM.
WPWV Worm Reducer — Industry Applications
⚊ Wide-Span Conveyor Drive Systems
Conveyor systems requiring the output shaft to span a wide belt drum or multi-drum arrangement use WPWV extended shaft for multi-point sprocket positioning.
⚒ Mining Multi-Equipment Chain Drives
Mining equipment chain drives requiring sprocket placement at multiple shaft points use WPWV extended shaft in universal body.
