Descrizione
WPWDKA Universal Speed Cast Iron Worm Gearbox
The most comprehensively specified A-type-input drive in the universal series — combining IEC direct motor connection (no input coupling), hollow bore shaft-mount output (no output coupling), and universal housing (all installation orientations) — is the WPWDKA Universal Speed Cast Iron Worm Gearbox. With D-type IEC motor flange in the A-type (below) input position, K-type hollow bore output, D-split housing for field service, and the WPW universal body, the WPWDKA delivers zero-coupling motorised shaft-mount performance in any installation orientation.

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.
