Description
WPWDA Universal Speed Cast Iron Worm Gearbox
OEM machine designs calling for a motorised below-entry input configuration in a universal housing — where one product must serve multiple machine variants with different mounting orientations while maintaining direct IEC motor connection — describe the WPWDA Universal Speed Cast Iron Worm Gearbox. Combining the WPW-series universal body, D-type IEC motor flange in the A-type (below) input position, and D-split housing for field serviceability, the WPWDA is the standard specification for motorised A-type-input universal drive systems.

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
■ D-IEC Flange (A-Input) + Universal W-Body: Motorised Below-Entry Universal Drive
The WPWDA integrates the D-type IEC motor flange in the A-type (below) input position into the WPW universal body, providing direct motorised drive capability across all 5 shaft direction configurations.
■ D-Split Housing for In-Situ Service
D-split housing cover removal allows worm wheel inspection without disturbing the motor or driven shaft — in all 5 shaft direction configurations of the WPWDA universal body.
■ Full IEC Frame Compatibility: M8 to M16
WPWDA accepts all standard IEC motor frames from M8 (0.06 kW, size 40) to M16 (14+ kW, size 250) across the universal body size range.
■ A-Type Input Oil Circuit — Validated for All 5 Shaft Directions
The WPWDA oil circuit is validated for the A-type (below) input shaft orientation across all 5 shaft direction configurations of the universal body.
■ Anti-Corrosion Coating Standard
Epoxy primer + polyurethane topcoat for resistance to process chemicals and cleaning agents in the diverse environments where the WPWDA’s versatility finds application.
■ 5 Shaft Direction Configurations Available with D-IEC Flange
All 5 shaft direction configurations (A–E) are available with the D-type IEC motor flange in A-input position — maintaining universal orientation support with motorised drive capability.
