WPWE Flange-Base Double Speed Worm Gear Reducer \u2014 Ultra-High Ratio Two-Stage Drive with Integral Flange Mounting Base<\/h1>\n

Large-scale stirring vessels, heavy rotary kilns, and robust process equipment drives face a recurring challenge: a two-stage gearbox providing ultra-high reduction ratios must be mounted securely enough to withstand the high torque reactions of 1\/600\u20131\/900 combined ratio operation without transmitting vibration to the supporting structure. The WPWE flange-base double speed worm gear reducer<\/strong> addresses this with an integral flanged base that distributes mounting forces over a larger bearing surface compared to the standard foot-mount WPEA series.<\/p>\n

The WPWE two-stage housing incorporates AC, BC (flange offset), and AD, BD (bolt pattern) dimensions that provide a rigid, bolt-down connection suitable for mounting directly onto machine base frames, vessel pedestals, and structural steelwork. Available in 9 size groups<\/strong> (40-70 through 155-250), ratios 1\/200\u20131\/900, 5 shaft-direction positions. The Z\u00d7L column in the specification table defines the foundation bolt specification for each size group. O Ever-power<\/a> | Request a Selection Guide<\/a><\/p>\n<\/section>\n

\"WPWE<\/div>\n
\n

The WPWE integrates the same two-worm-pair cascade as the WPEA with a wider, flanged base section that extends laterally beyond the housing sides. This flanged base provides multiple bolt-down points that distribute the reaction torque of the two-stage gear system over a larger area \u2014 reducing concentrated stresses at individual mounting points and providing a more stable, vibration-resistant installation. The base surface is precision-machined for flat contact with the mounting structure.<\/p>\n\n\n\n\n\n\n\n

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

Enhanced Mounting Rigidity for High-Torque Two-Stage Drives<\/h3>\n

At combined ratios of 1\/600\u20131\/900, the reaction torque transmitted to the gearbox mounting is very high \u2014 considerably higher than any single-stage product. The WPWE flanged base distributes this reaction torque over a larger mounting footprint, reducing the risk of bolt loosening, structural fatigue, and frame distortion in long-term heavy-duty applications. Keywords: heavy-duty flange-base two-stage worm gearbox, rigid mount double speed reducer.<\/em><\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Integral Base \u2014 No Separate Baseplate Required<\/h3>\n

The flanged base is cast and machined as part of the housing \u2014 not a separate adapter or base frame. This eliminates a potential misalignment interface and simplifies the installation bill of materials. The base is precision-machined flat to ensure full contact with the mounting structure without shimming under normal conditions.<\/p>\n<\/div>\n

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

Same Two-Stage Ratio Range as WPEA<\/h3>\n

The WPWE delivers the full 1\/200\u20131\/900 ratio range of the WPEA series, with identical gear pair specifications, equivalent output torque ratings, and the same worm shaft and output shaft dimensions. The flanged base is the only dimensional difference \u2014 making the WPWE a direct mounting-upgrade for WPEA applications where improved installation rigidity is required.<\/p>\n<\/div>\n

\n
<\/div>\n

Five Shaft-Direction Options<\/h3>\n

Standard positions A through E maintain the installation flexibility of the WPE series, allowing the WPWE to be integrated into reaction vessel pedestals, heavy machine frames, and process equipment bases from any input shaft direction.<\/p>\n<\/div>\n

\n
<\/div>\n

Splash Oil Bath for Both Stages<\/h3>\n

The WPWE shared oil bath serves both gear stages. The wider housing provides slightly more oil volume than the WPEA equivalent, improving heat dissipation and lubricant service life. For the most demanding continuous applications, the WPWED (motor-direct flanged-base with cooling fins) is available.<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking at High Combined Ratios<\/h3>\n

At combined ratios of 1\/400 and above, the WPWE provides passive self-locking \u2014 preventing back-driving of connected loads. Combined with the rigid flanged base, this makes the WPWE a secure static positioning drive for large vessel stirrers and heavy rotating equipment that must hold position when de-energised.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
