WPZ Vertical Output Single Speed Worm Gear Reducer \u2014 Upward-Shaft Drive for Screw Conveyors, Bucket Elevators & Vertical Lifting<\/h1>\n

Conventional horizontal-output worm gearboxes require angle drives, bevel gears, or complex shaft arrangements when the application demands an upward-pointing output shaft. The WPZ vertical output worm gear reducer<\/strong> eliminates this complexity by delivering its output torque on a shaft that points vertically \u2014 making it the direct-drive solution of choice for screw conveyors, bucket elevators, vertical mixing shafts, and any machine architecture requiring an upward output axis.<\/p>\n

The WPZ features a compact upright housing where the output shaft exits through the top face and the input shaft is horizontal \u2014 creating a 90\u00b0 power turn in the most space-efficient possible geometry. Available in 7 frame sizes<\/strong> (50\u2013135 mm) with ratios 1\/5 to 1\/60 and three shaft-direction configurations. The integral oil-fill system is designed specifically for this vertical-output orientation, ensuring correct gear and bearing lubrication without additional provisions. \u30a8\u30d0\u30fc\u30d1\u30ef\u30fc\u306b\u3064\u3044\u3066<\/a> | \u898b\u7a4d\u3082\u308a\u3092\u4f9d\u983c\u3059\u308b<\/a><\/p>\n<\/section>\n

\"WPZ<\/div>\n
\n

The WPZ housing is a compact upright block with a flat base and a side-mounted input (worm) shaft bore. The worm wheel shaft exits through the top face as the vertical output shaft. This geometry achieves a 90\u00b0 power turn in the smallest possible package while maintaining a stable flat base for direct bolt-down mounting to screw conveyor frames, elevator bases, or vertical machine structures.<\/p>\n\n\n\n\n\n\n\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
\u2b06\ufe0f<\/div>\n
\n

Purpose-Built Vertical Output<\/h3>\n

Unlike horizontal gearboxes retrofitted for vertical applications, the WPZ is designed from the ground up for vertical output. The housing, bearing arrangement, oil fill system, and shaft seals are all optimised for upward-pointing output shaft operation \u2014 ensuring reliable lubrication and long seal life in this specific orientation. Keywords: vertical output worm gearbox, upward shaft worm reducer.<\/em><\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Compact 90\u00b0 Power Turn<\/h3>\n

The WPZ achieves a precise 90\u00b0 power turn (horizontal input \u2192 vertical output) in the most compact possible geometry, reducing the vertical drive stack height on screw conveyors and bucket elevators compared to bevel-gear or right-angle gearbox alternatives.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Self-Locking for Vertical Load Holding<\/h3>\n

At ratios of 1\/30 and above, the WPZ provides worm self-locking behaviour that prevents back-driving under static vertical load. This is particularly valuable for screw conveyors and vertical lifting applications where preventing uncontrolled reversal under gravity load is a safety requirement.<\/p>\n<\/div>\n<\/div>\n

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

Flat-Base Direct Bolt-Down Mounting<\/h3>\n

The WPZ flat base bolts directly to conveyor frames, elevator base structures, and vertical machine platforms without adapter plates or angle brackets \u2014 simplifying installation and reducing the number of threaded interfaces subject to vibration loosening.<\/p>\n<\/div>\n<\/div>\n

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

Precision Worm Pair \u2014 Low Noise<\/h3>\n

Ground worm and bronze wheel to ISO 1328 Grade 7 deliver quiet operation (\u226472 dB(A)) essential in industrial environments. Efficiency 60\u201390% per ratio ensures cost-effective energy consumption across continuous screw conveyor and elevator operation.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Three Input Shaft Directions<\/h3>\n

Positions A, B, C allow the motor to be positioned on either side of the housing or from above, accommodating different machine layout constraints in screw conveyor and elevator drive assemblies.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

\n

Industry Applications<\/h2>\n

The WPZ vertical output worm reducer is the purpose-designed drive for vertical screw, auger, and elevator applications:<\/p>\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. WPZ units are run-tested in their design vertical-output orientation \u2014 not simply in horizontal position and then rotated \u2014 ensuring lubrication adequacy and seal integrity are verified under actual operating conditions.<\/p>\n<\/div>\n

\n

\u2b06\ufe0f Vertical Orientation Run Test<\/h3>\n

Each WPZ is tested with output shaft vertical<\/strong> for 30 minutes at rated torque. Oil sump temperature, noise level, and seal leakage are all measured in this orientation, not translated from horizontal test data \u2014 providing genuine assurance that the unit performs correctly in service.<\/p>\n<\/div>\n

\n

Material Standards<\/h3>\n

Housing: FC25 cast iron (\u2265250 MPa). Worm: 20CrMnTi (\u226558 HRC). Wheel: ZCuSn10Pb1 tin-bronze. All materials GB\/T and IEC compliant; third-party SGS\/BV inspection available for grain industry and food safety certification requirements.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
