WPEDKA Flange-Mounted Hollow Shaft Double Speed Worm Gear Reducer \u2014 Zero Couplings at Both Ends with Ultra-High Two-Stage Ratio<\/h1>\n

The WPEDKA<\/strong> is the product in the WPE two-stage family that eliminates couplings at both<\/em> the motor input and the driven shaft output simultaneously \u2014 while delivering the extreme 1\/200\u20131\/900 reduction ratios that no single-stage product can achieve. The IEC motor flange at the input eliminates the motor coupling; the H7 hollow output bore eliminates the output shaft coupling. The complete drive chain from motor to process shaft consists of just three components: motor + WPEDKA + driven shaft.<\/p>\n

This maximum integration makes the WPEDKA the ideal solution for automotive conveyor lines, logistics automation, and high-density material handling systems<\/em> where every eliminated coupling reduces maintenance events across hundreds of installed drive points. Available in 9 size groups<\/strong>, motors 0.12\u20135.5 kW, bore 30\u2013110 mm, ratios 1\/200\u20131\/900. O Ever-power<\/a> | Request a Quote<\/a><\/p>\n<\/section>\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
\u26a1<\/div>\n

Zero Couplings at Both Ends with 1\/200\u20131\/900 Ratios<\/h3>\n

The WPEDKA is unique in eliminating couplings at both<\/em> the motor input (IEC flange) and the driven shaft output (hollow bore) while simultaneously achieving two-stage 1\/200\u20131\/900 reduction. No other product type achieves this three-feature combination. Keywords: motor-direct hollow shaft double speed worm gearbox, zero-coupling two-stage reducer.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

IEC Flange \u2014 15-Minute Motor Swap<\/h3>\n

In high-density material handling systems with dozens of identical drive points, the IEC flange enables motor replacement in under 15 minutes \u2014 no coupling removal, no alignment re-check. Across a 50-unit conveyor system, this reduction in per-motor maintenance time has significant measurable value.<\/p>\n<\/div>\n

\n
<\/div>\n

H7 Hollow Bore \u2014 Direct Shaft Engagement<\/h3>\n

The H7 precision hollow bore accepts conveyor roller shafts, material handling drive shafts, and logistics equipment shafts from 30 mm to 110 mm ground to h6\/js6 \u2014 with no field reaming, no coupling hub, and no alignment tooling required at the output end.<\/p>\n<\/div>\n

\n
<\/div>\n

Eliminates Both Coupling Costs Simultaneously<\/h3>\n

One WPEDKA replaces a gearbox PLUS two couplings (one motor-side, one shaft-side). For OEM machine builders sourcing hundreds of drive units for a logistics facility or automotive line, eliminating two coupling SKUs from the BOM and two coupling maintenance procedures from the service manual is a compelling TCO argument.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

FC25 Cast Iron for Industrial Conveyor Environments<\/h3>\n

The elongated two-stage FC25 housing withstands the vibration, dust, and intermittent shock loads typical of automotive conveyor and logistics automation environments \u2014 where multiple drive units operate simultaneously under variable load conditions.<\/p>\n<\/div>\n

\n
<\/div>\n

Full Motor Range 0.12\u20135.5 kW<\/h3>\n

Nine size groups accept motors from 0.12 kW (small positioning and indexing drives) to 5.5 kW (heavy conveyor roller drives) \u2014 covering the entire range of material handling and logistics automation drive requirements.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Dual Interface Run Test<\/h3>\n

Each WPEDKA undergoes: (1) IEC flange concentricity CMM check (\u22640.05 mm TIR), (2) hollow bore H7 plug gauge, (3) bore concentricity check (\u22640.05 mm TIR), (4) 45-min two-stage run test \u2014 noise \u226475 dB(A), seal integrity, torque \u00b15%. Both interface dimensions AND gear performance verified on every unit.<\/p>\n<\/div>\n

\n

OEM Batch Consistency<\/h3>\n

For automotive and logistics OEM batch supply, we maintain batch-to-batch dimensional consistency records for both the IEC flange and hollow bore interfaces. OEM customers can specify a dimensional consistency window tighter than our standard tolerance for high-volume automated assembly line supply programmes.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
