WPEDA Flange-Mounted Double Speed Worm Gear Reducer \u2014 Motor-Direct Two-Stage Drive for Ultra-High Ratio Compact Process Equipment<\/h1>\n

When a large food processing machine, pharmaceutical vessel, or continuous industrial mixer requires a combined ratio of 1\/200\u20131\/900 from a direct motor-mounted drive \u2014 without the coupling alignment complexity of indirect drive arrangements \u2014 the WPEDA flange-mounted double speed worm gear reducer<\/strong> is the engineered answer. The IEC motor flange at the first-stage input eliminates the coupling between motor and gearbox, while the two-stage worm gear cascade delivers the extreme speed reduction that no single-stage product can achieve.<\/p>\n

Accepting motors from 0.12 kW to 5.5 kW<\/strong> across 9 size groups (40-70 through 155-250 mm combined centre distance), the WPEDA covers the full range of motor-direct two-stage applications from small laboratory stirrers to large industrial agitator vessels. Five shaft-direction positions (A\u2013E) ensure integration flexibility. Motor flange dimensions comply with IEC 60034-7.

Product Structure \u2014 IEC Flange + Two-Stage Worm Cascade<\/h2>\n
\n
\"WPEDA<\/div>\n
\n

The WPEDA housing integrates an IEC motor flange at the first-stage worm shaft input \u2014 the motor shaft slides directly into the keyed input bore, eliminating the coupling entirely. The two-stage worm cascade then reduces the motor speed through two sequential gear meshes, delivering the ultra-high reduction ratio at the solid output shaft. This creates a compact motor + two-stage gearbox assembly with no intermediary coupling components.<\/p>\n\n\n\n\n\n\n\n

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

Motor-Direct + Ultra-High Ratio \u2014 Unique Combination<\/h3>\n

The WPEDA uniquely combines IEC direct motor mounting (no coupling) with two-stage ultra-high ratio reduction (1\/200\u20131\/900). This means the entire drive chain from motor to process shaft contains no coupling elements, while achieving the extreme reduction ratios that food processing, pharmaceutical, and industrial stirrer applications require. Keywords: motor-direct double speed worm gearbox, IEC flange two-stage worm reducer.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

IEC Flange Eliminates Alignment Complexity<\/h3>\n

Two-stage gearboxes are longer and heavier than single-stage units \u2014 making coupling misalignment a more significant concern. The WPEDA IEC flange eliminates this issue entirely by placing the motor shaft directly in the input bore, under the constraint of the precision pilot register, without any separate coupling alignment step.<\/p>\n<\/div>\n

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

Two-Stage Precision for Ultra-Low Process Speeds<\/h3>\n

Both worm pairs are ground to ISO 1328 Grade 7 tolerances. For food processing, pharmaceutical, and chemical stirrer applications requiring very slow, highly controlled output speeds (1\/200\u20131\/900 of motor speed), the two-stage precision provides smooth, uniform rotation free from gear-induced velocity variations.<\/p>\n<\/div>\n

\n
<\/div>\n

Wide Motor Power Range \u2014 0.12 to 5.5 kW<\/h3>\n

Nine size groups accept motors from 0.12 kW (size 40-70, light laboratory stirrer applications) to 5.5 kW (size 155-250, large industrial vessel drives). This span covers the vast majority of motor-direct two-stage drive requirements within the food, pharmaceutical, and chemical processing industries.<\/p>\n<\/div>\n

\n
<\/div>\n

Five Output Shaft Directions<\/h3>\n

Standard positions A through E accommodate horizontal, inclined, and various angled output shaft orientations \u2014 providing the same installation flexibility as the foot-mount WPEA series within the motor-direct WPEDA format.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

FC25 Cast Iron Body for Industrial Durability<\/h3>\n

The elongated two-stage FC25 cast iron housing delivers the impact resistance and vibration damping characteristic of the WPE series, ensuring long service life in food processing environments subject to vibration from adjacent equipment, wash-down operations, and thermal cycling.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
