WPWV Universal Speed Cast Iron Worm Gearbox
Extended output shaft drives — applications where the gearbox output shaft must be longer than standard to span a distance, drive multiple sprockets, or connect to equipment spaced far from the gearbox body — in a universal housing platform require combining V-type extended output geometry with universal installation orientation support. The WPWV Universal Speed Cast Iron Worm Gearbox provides the WPW-series universal body with V-type extended solid output shaft across 5 shaft direction configurations. Extended shaft drives from ratio 1/5 to 1/60 in any installation orientation from a single standard product.

Universal W-Body Structure
The WPW-series universal housing is manufactured as a single FC20+ grey cast iron casting with bore positions, keyway orientations, and oil channels configured for the selected shaft direction. All 5 shaft direction configurations (A/B/C/D/E) use the same casting geometry with specific machining per configuration.
Hardened 20CrMnTi steel worm shaft with case-hardened tooth flanks (55–60 HRC). The worm shaft and its bearings are selected for the specific input orientation of the model — A-type (below), S-type (overhead), or bilateral — ensuring rated bearing life in the correct load direction.
Tin-bronze ZCuSn10Pb1 alloy worm wheel machined to mesh precisely with the hardened worm shaft. The bronze material provides excellent anti-seizure properties and wear-in characteristics for the worm gear mesh.
Output shaft in quenched-and-tempered steel with double-lip oil seals rated for the specific output orientation (horizontal, vertical upward O-type, vertical downward X-type, side T-type, or extended V-type). Seal selection matches the hydrostatic pressure requirements of the installed orientation.
Single-stage oil bath lubrication. Oil fill port, oil gauge, vent plug, and drain plug are positioned for the selected shaft direction configuration. Fill quantities are specified per configuration in the installation guide — do not use generic fill values across configurations.
FC20+ cast iron foot-mount base integrated with the housing casting. Four mounting holes for B3 foot mounting. The base orientation is fixed for the selected shaft direction configuration. For shaft-mount (hollow bore) applications, the torque arm boss provides housing restraint.
Core Features & Benefits
■ Universal W-Body + V Extended Output Shaft: Long Shaft Drive in Any Orientation
WPWV provides V-type extended solid output shaft in all 5 WPW shaft direction configurations. Extended output shaft length across any installation orientation from one standard product.
■ V-Type Extended Shaft: Greater Span from Gearbox Body
The V-type extended output shaft is longer than the standard output shaft — providing greater reach from the gearbox housing face for multi-sprocket, wide drum, or spanning applications.
■ Extended Shaft Rated for Overhang Loads
The V-type extended shaft is designed with the shaft diameter and bearing specification to handle the overhang bending moment generated by the extended shaft length and loads applied at the shaft end.
■ Full WP Torque Through Extended Shaft
WPWV V-type extended output is rated for full WP output torques — up to 4,796 Nm at size 250 — subject to the overhang load limits specified for the extended shaft length.
■ 5 Shaft Direction Configurations Available
All 5 shaft direction configurations (A–E) available for the WPWV with V-type extended output. Universal orientation with extended shaft capability.
■ Ratios 1/5–1/60 in All V-Output Configurations
Full WP ratio range available in all WPWV configurations.
