WPWDK Flange-Mounted Universal Hollow Shaft Worm Gear Reducer \u2014 Zero Couplings at Both Ends with Universal Multi-Orientation Mounting<\/h1>\n

Every coupling in a drive system is a maintenance point, an alignment task, and a potential failure mode. The WPWDK flange-mounted universal hollow shaft worm gear reducer<\/strong> eliminates couplings at both the motor input and the driven shaft output simultaneously \u2014 IEC flange at the front accepts the motor shaft directly; H7 hollow bore at the back accepts the driven shaft directly. The result is the most mechanically streamlined drive configuration in the entire WPW universal series: motor + WPWDK + driven shaft, three components, zero couplings.<\/p>\n

Combined with the WPW universal flanged base supporting multiple mounting orientations, the WPWDK is the definitive motor-direct hollow shaft drive for conveyor roller drives, logistics automation, and machine tool auxiliaries<\/em> requiring zero-coupling simplicity at any installation angle. Motors 0.12\u201315 kW, bore 18\u2013110 mm, ratios 1\/5\u20131\/60, 12 size groups. About Ever-power<\/a> | Get a Free Selection Quote<\/a><\/p>\n<\/section>\n

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

Zero Couplings at Both Ends \u2014 On a Universal-Mount Platform<\/h3>\n

No other WPW product eliminates couplings at both the motor and driven shaft ends AND provides multi-orientation universal mounting simultaneously. WPWD eliminates the motor coupling but has solid shaft output. WPWK eliminates the output coupling but uses standard input shaft. WPWDK eliminates both \u2014 on the universal platform. Keywords: zero-coupling universal worm reducer, IEC flange hollow shaft universal gearbox.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

15-Minute Motor Swap at Any Mounting Angle<\/h3>\n

IEC pilot register enables motor change in under 15 minutes regardless of whether the unit is horizontal, inclined, or vertical. For conveyor systems and logistics facilities with multiple installed units at varied angles, this consistent maintenance procedure reduces per-motor service time regardless of orientation.<\/p>\n<\/div>\n

\n
<\/div>\n

Hollow Bore Direct Shaft \u2014 No Alignment Required at Output<\/h3>\n

H7 bore accepts the driven shaft without field reaming, coupling hub fitting, or alignment tools. Combined with the IEC flange motor input, the entire WPWDK installation procedure involves: motor bolting (IEC flange) + shaft insertion (hollow bore) + base anchor bolting. No alignment tasks anywhere in the drive chain.<\/p>\n<\/div>\n

\n
<\/div>\n

Universal Mounting \u2014 One Product for All Machine Orientations<\/h3>\n

The WPW flanged base multi-orientation capability allows one WPWDK specification to cover horizontal, inclined, and near-vertical conveyor and machine drives. OEM machine builders standardising on WPWDK carry one SKU for all machine variants regardless of mounting angle.<\/p>\n<\/div>\n

\n
<\/div>\n

Widest Motor Range in the DK Series \u2014 0.12 to 15 kW<\/h3>\n

Twelve size groups accepting 0.12 kW to 15 kW cover the complete range of zero-coupling universal drive requirements \u2014 from small packaging machine indexing drives (size 40) to large industrial conveyor head drives (size 250).<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking in All Orientations<\/h3>\n

At ratios \u22651\/30, the WPWDK self-locks in any supported orientation \u2014 providing passive load holding at both shaft ends simultaneously (motor side locked by the IEC keyed bore; driven shaft side locked by the hollow bore keyway). No additional holding brake required in many conveyor and machine applications.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
