WPWED Flange-Base Motor-Direct Double Speed Worm Gear Reducer \u2014 The Most Rigidly Mounted Motor-Direct Ultra-High Ratio Drive<\/h1>\n

When large-scale pharmaceutical fermentation vessels, heavy chemical reactors, or substantial biogas digesters require a two-stage 1\/200\u20131\/900 drive, two installation priorities must be met simultaneously: the motor must connect directly without a coupling (for compactness and maintenance simplicity), and the gearbox must be anchored with maximum rigidity to withstand the high reaction torques of two-stage operation at very high combined ratios. The WPWED flange-base motor-direct double speed worm gear reducer<\/strong> is engineered to satisfy both requirements.<\/p>\n

Combining the IEC motor flange of the WPEDA series with the integral flanged anchor base of the WPWE series, the WPWED delivers motor-direct two-stage ultra-high ratio reduction anchored by multiple base bolts to the supporting structure \u2014 the most rigidly mounted, most installation-integrated product in the WPE two-stage family. Available in 9 size groups<\/strong>, motors 0.12\u20135.5 kW, ratios 1\/200\u20131\/900. About Ever-power<\/a> | Request a Selection Guide<\/a><\/p>\n<\/section>\n

\"WPWED<\/div>\n

The WPWED is the structural integration of three features in one casting: an IEC motor flange at the first-stage input (motor direct, no coupling), a two-stage worm cascade delivering ultra-high reduction, and a wide flanged base with multiple anchor bolt positions distributing the reaction torque over a large mounting footprint. The base is precision-machined to \u22640.05 mm flatness, ensuring full contact with the mounting pedestal.<\/p>\n\n\n\n\n\n\n\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
<\/div>\n

Motor-Direct + Two-Stage + Flanged Base \u2014 Highest Integration in WPE Series<\/h3>\n

The WPWED combines the three most important features of the WPE product family in a single casting: IEC motor direct-mount (WPEDA feature), ultra-high ratio two-stage reduction (common to all WPE), and flanged base anchor mounting (WPWE feature). This is the most structurally integrated motor-direct two-stage product available. Keywords: flanged-base motor-direct double speed worm gearbox, rigid anchor-mount two-stage reducer.<\/em><\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Maximum Reaction Torque Resistance<\/h3>\n

At combined ratios of 1\/600\u20131\/900 with 3\u20135.5 kW motors, the reaction torque transmitted to the gearbox mounting is substantial. The WPWED flanged base with multiple anchor bolts distributes this reaction torque over the largest mounting footprint of any product in the WPE series \u2014 preventing bolt loosening, structural fatigue, and vibration transmission to the supporting frame.<\/p>\n<\/div>\n

\n
<\/div>\n

IEC Flange for Rapid Motor Maintenance<\/h3>\n

In pharmaceutical and chemical process environments where motor replacement must be completed quickly to minimise batch cycle disruption, the IEC pilot register allows motor swap in under 20 minutes \u2014 no coupling removal, no alignment re-check, no re-calibration of mounting bolts in the flanged base.<\/p>\n<\/div>\n

\n
\u2699\ufe0f<\/div>\n

Two-Stage Precision at Very High Torque Loads<\/h3>\n

Both worm pairs ground to ISO 1328 Grade 7 deliver smooth, uniform output at the ultra-low speeds and very high torques characteristic of large vessel agitator and heavy process drive applications. Smooth output is critical for processes involving viscous materials where gear-induced velocity variation causes non-uniform mixing.<\/p>\n<\/div>\n

\n
<\/div>\n

No Additional Baseplate Required<\/h3>\n

The integral flanged base eliminates the need for a separate motor-gearbox baseplate. The WPWED bolts directly to the vessel pedestal, machine frame, or structural concrete foundation \u2014 saving both cost and the alignment interface of a separate baseplate installation.<\/p>\n<\/div>\n

\n
<\/div>\n

Full Size Range \u2014 0.12 to 5.5 kW<\/h3>\n

Nine size groups cover the full range from small pharmaceutical vessel drives (0.12 kW, 1\/900 ratio) to large industrial process drives (5.5 kW, 1\/200\u20131\/900 ratio), providing a single standardised product family for motor-direct flanged-base two-stage applications.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
