WPWDKO Flange-Mounted Universal Hollow Shaft Worm Gear Reducer \u2014 Zero Couplings at Both Ends, Up to Six Mounting Orientations, for Port & Crane Hollow Shaft Drives<\/h1>\n

Port cranes, inclined mine conveyors, and vertical process equipment often demand three simultaneous drive requirements: motor-direct coupling-free input (for maintenance simplicity in remote or elevated installations), hollow bore coupling-free shaft output (for compact drum shaft engagement without coupling hardware), and non-standard mounting orientations beyond horizontal. The WPWDKO flange-mounted universal hollow shaft worm gear reducer<\/strong> is the only product in the WPW series that satisfies all three simultaneously.<\/p>\n

IEC motor flange at input, H7 hollow bore at output, reinforced bearings for vertical and inclined loads, multi-face oil ports for correct lubrication at each position, and up to six mounting orientations (A\u2013D). Motors 0.12\u201315 kW, bore 16\u2013110 mm, ratios 1\/5\u20131\/60. \u0e40\u0e01\u0e35\u0e48\u0e22\u0e27\u0e01\u0e31\u0e1a\u0e40\u0e2d\u0e40\u0e27\u0e2d\u0e23\u0e4c\u0e1e\u0e32\u0e27\u0e40\u0e27\u0e2d\u0e23\u0e4c<\/a> | Get a Technical Consultation<\/a><\/p>\n<\/section>\n

The WPWDKO unites the IEC motor flange of the WPWDK with the multi-direction housing of the WPWKO. The motor shaft enters the IEC keyed bore at the input; the driven shaft engages the H7 hollow bore at the output; the housing body supports multiple mounting orientation positions with reinforced output bearings for vertical and inclined load vectors and multi-face oil ports for each position.<\/p>\n\n\n\n\n\n\n\n

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

Three Zero-Coupling Features at Any Mounting Angle<\/h3>\n

The WPWDKO is unique in the WPW series: it eliminates the motor coupling (IEC flange), eliminates the output coupling (hollow bore), AND supports vertical and non-standard mounting orientations (multi-direction housing). WPWDKO = no input coupling + no output coupling + any mounting angle. No other WPW product provides all three simultaneously. Keywords: zero-coupling multi-direction hollow shaft worm reducer, IEC flange hollow bore vertical worm gearbox.<\/em><\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Port & Crane \u2014 Rapid Motor Swap at Any Installation Angle<\/h3>\n

For crane hoist drum drives mounted at elevated, inclined, or vertical positions, the IEC motor flange enables motor replacement in under 15 minutes without disturbing the drum shaft connection \u2014 the hollow bore stays engaged while the motor is exchanged. This rapid swap capability is particularly valuable for port machinery where crane downtime is measured in lost ship turnaround revenue.<\/p>\n<\/div>\n

\n
<\/div>\n

Correct Oil System for Zero-Coupling Vertical Service<\/h3>\n

The WPWDKO multi-face oil port system maintains correct gear mesh and bearing lubrication in vertical service with the hollow bore output \u2014 the position-specific oil fill instruction sheet specifies the correct port for each rated orientation, ensuring proper lubrication even at the most demanding vertical hollow bore service conditions.<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking Vertical Hollow Shaft Drive<\/h3>\n

At ratios \u22651\/30, the WPWDKO self-locks in vertical orientation \u2014 preventing back-driving of crane hoist drums, ship winches, and vertical agitator shafts when the motor is de-energised. With the hollow bore rigidly engaged, self-locking holds the driven shaft securely without any separate parking brake in many applications.<\/p>\n<\/div>\n

\n
<\/div>\n

H7 Precision Bore \u2014 No Field Reaming at Remote Installations<\/h3>\n

For crane and port machinery installations where field machining is impractical or impossible, the H7 ground bore accepts pre-ground drum shafts without any on-site bore correction \u2014 important for elevated or offshore installations where machine tools are unavailable.<\/p>\n<\/div>\n

\n
<\/div>\n

0.12 to 15 kW Motor Range \u2014 All Crane Auxiliary Drives<\/h3>\n

Twelve sizes from 40 to 250 mm cover the complete range of crane auxiliary hollow shaft drives from small hatch cover mechanism motors (size 40, 0.12 kW) to large deck crane slewing drum drives (size 250, 15 kW).<\/p>\n<\/div>\n<\/div>\n<\/section>\n
