WPDO Flange-Mounted Vertical Single Speed Worm Gear Reducer \u2014 Compact Motor-Direct Drive for Non-Standard and Vertical Installation<\/h1>\n

Modern machine design increasingly demands drive components that can be installed in non-standard orientations \u2014 vertical lift shafts, inclined conveyor heads, gate post assemblies, and pump tower drives all require a gearbox that is as flexible in mounting as it is reliable in operation. The WPDO flange-mounted vertical worm gear reducer<\/strong> answers this need by combining an IEC motor direct-mount flange with up to six output shaft orientation configurations (A\u2013F), covering the full range from horizontal to fully vertical installations.<\/p>\n

The WPDO delivers the same precision worm-and-wheel performance as the WPDA series \u2014 the same FC25 cast iron housing, the same ZCuSn10Pb1 bronze worm wheel, the same \u226472 dB(A) noise specification \u2014 but with an extended oil-plug arrangement that maintains correct lubrication regardless of mounting angle. Available in 12 frame sizes<\/strong> (40\u2013250 mm), motor powers from 0.12 to 15 kW, and ratios from 1\/5 to 1\/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> | Request a Layout Consultation<\/a><\/p>\n<\/section>\n

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

Six Mounting Positions \u2014 Maximum Layout Freedom<\/h3>\n

Up to six shaft-direction configurations (A\u2013F) allow the WPDO to be installed horizontally, vertically with output shaft pointing up or down, and at intermediate angles. Combined with motor-direct input, this is the most installation-flexible product in the WP series. Keywords: vertical mount motor-direct gearbox, multi-position flange worm reducer.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Motor-Direct IEC Flange \u2014 No Coupling, No Alignment<\/h3>\n

The precision IEC 60034-7 pilot register eliminates coupling selection, alignment checking, and post-maintenance re-alignment. Motor shaft slides directly into the keyed input bore \u2014 the single most time-saving feature for maintenance technicians working in confined vertical shaft housings.<\/p>\n<\/div>\n

\n
<\/div>\n

Multi-Face Oil System for Correct Vertical Lubrication<\/h3>\n

Unlike the WPDA which has a single oil fill point optimised for horizontal mounting, the WPDO incorporates oil-fill and drain plugs on multiple housing faces. This ensures the worm gear set is correctly immersed in oil regardless of the mounting angle \u2014 a critical design detail that prevents premature wear in vertical installations.<\/p>\n<\/div>\n

\n
<\/div>\n

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

At ratios of 1\/30 and above, the worm lead angle falls below the friction angle, providing passive load-holding. In vertical drive applications such as gate actuators, lift platforms, and vertical conveyors, this reduces the holding brake duty cycle and serves as a secondary safety measure against uncontrolled lowering.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Rugged Cast Iron with Reinforced Vertical Bearings<\/h3>\n

The FC25 cast iron housing and reinforced output shaft bearing selection handle the combined axial and radial loads specific to vertical and inclined mounting configurations, ensuring bearing life targets are met even in full vertical orientation under rated load.<\/p>\n<\/div>\n

\n
<\/div>\n

Full Range Compatibility \u2014 0.12 to 15 kW<\/h3>\n

12 frame sizes from 40 to 250 mm, accepting motors from 0.12 kW to 15 kW, cover the widest range of vertical and inclined drive applications \u2014 from small gate actuators to large vertical pump and stirring tower drives.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

The WPDO is the motor-direct solution of choice for any drive application where horizontal foot-mounting is not possible:<\/p>\n

\n
\n
<\/div>\n

Gate & Barrier Automation<\/strong>Industrial gate drive systems, parking barrier actuators, and security shutter motors where the WPDO’s vertical mounting and self-locking capability fit neatly into a gate post housing with a direct-mount motor.<\/span><\/div>\n

\n
\ufe0f<\/div>\n

Construction & Lifting Equipment<\/strong>Compact goods lifts, scissor lift table drives, and building material hoist auxiliaries where vertical motor-gearbox integration reduces the drive envelope height in the lift shaft.<\/span><\/div>\n

\n
<\/div>\n

Agricultural Irrigation Systems<\/strong>Centre-pivot irrigation drive motors, automated vent systems in greenhouses, and feed auger drives where outdoor mounting at non-standard angles is common and direct motor attachment simplifies maintenance.<\/span><\/div>\n

\n
<\/div>\n

Vertical Pump Drives<\/strong>Vertical pump tower drives, tank agitator motor-gearbox units, and deep well pump auxiliaries where the motor-direct vertical gearbox eliminates the need for a separate motor plate and coupling in the pump head assembly.<\/span><\/div>\n

\n
<\/div>\n

Marine Deck Equipment<\/strong>Hatch cover drive systems, winch auxiliaries, and anchor chain guide drives on vessels where installation space dictates vertical or inclined motor-gearbox positioning in the deck structure.<\/span><\/div>\n

\n
<\/div>\n

Special Machine Auxiliaries<\/strong>Any industrial machine where the motor must be mounted perpendicular to the ground plane (column drilling machines, vertical axis rotary tables, lathe tail-stock drives) and standard horizontal gearboxes cannot be used.<\/span><\/div>\n<\/div>\n<\/section>\n

\n

Quality Control & Certification<\/h2>\n
\n
\n

ISO 9001:2015 & CE<\/h3>\n

Full ISO 9001:2015 QMS with CE Declaration of Conformity per shipment. The WPDO’s multi-position oil-plug system is verified against the EN ISO 12100 machinery safety standard, and IEC flange dimensions are CMM checked to \u22640.05 mm TIR.<\/p>\n<\/div>\n

\n

\ufe0f Multi-Orientation Run Test<\/h3>\n

Each WPDO unit is run-tested in both horizontal and vertical orientations to verify oil film formation, bearing lubrication adequacy, and oil-seal integrity in all specified mounting positions. Sump temperature and noise levels are measured in each orientation before shipment approval.<\/p>\n<\/div>\n
