WPS Single Speed Worm Gear Reducer with Cooling Fins \u2014 Thermally Optimised for Continuous Heavy-Duty Operation<\/h1>\n

When a drive system must operate at high duty cycles \u2014 multiple daily shifts, near-continuous running, or elevated ambient temperatures \u2014 heat management becomes the critical constraint. The WPS worm gear reducer<\/strong> directly addresses this challenge. Deep longitudinal cooling fins machined into the cast iron housing dramatically increase external surface area for natural convection cooling, reducing sustained operating temperatures by up to 15\u00b0C compared to a standard smooth-body unit of equivalent size.<\/p>\n

This thermal advantage translates directly into longer lubricant life, reduced seal wear, and extended overhaul intervals \u2014 making the WPS the recommended choice for heavy-duty worm gear reducers<\/em> in metallurgical, chemical, aggregate processing, and 24\/7 production environments. Available in sizes 40\u2013250 mm<\/strong>, nine ratios (1\/5\u20131\/60), and five shaft-direction positions.

\u2705 Key Features & Benefits<\/h2>\n
\n
01<\/span><\/p>\n

Integral Cooling Fin Architecture<\/h3>\n

Cast-integral fins increase external surface area by up to 40%, enabling natural convection cooling sufficient to eliminate external fans or cooling circuits even in compact plant rooms. Ideal for continuous-duty worm gearbox<\/em> applications in hot climates.<\/p>\n<\/div>\n

02<\/span><\/p>\n

Extended Lubricant & Seal Life<\/h3>\n

Lower steady-state oil temperature extends ISO VG 320 mineral oil change intervals, reduces oxidation and additive depletion, and dramatically slows NBR seal degradation \u2014 cutting total cost of ownership in shift-pattern manufacturing environments.<\/p>\n<\/div>\n

03<\/span><\/p>\n

Rugged FC25 Cast Iron Body<\/h3>\n

Grey cast iron housing provides inherent vibration damping and outstanding impact resistance, making the WPS suitable for metallurgical facilities, crusher drives, and any application subject to shock or cyclic loading. Keywords: heavy-duty worm drive for metallurgy.<\/em><\/p>\n<\/div>\n

04<\/span><\/p>\n

Precision Ground Worm Pair<\/h3>\n

Ground worm tooth profile mated with ZCuSn10Pb1 bronze wheel delivers low noise (\u226472 dB(A)) and smooth torque transfer with efficiency up to 90% at 1\/5 ratio \u2014 combining quiet running with energy efficiency even under heavy sustained loads.<\/p>\n<\/div>\n

05<\/span><\/p>\n

Five Shaft-Direction Options<\/h3>\n

Standard positions A through E accommodate virtually any drive-train layout, simplifying integration into new designs and retrofits without structural modification \u2014 a crucial feature for multi-shift plants where downtime for drive realignment is unacceptable.<\/p>\n<\/div>\n

06<\/span><\/p>\n

Drop-In Replacement for WPA<\/h3>\n

The WPS shares the identical base footprint and shaft dimensions with the WPA. It can be fitted as a like-for-like thermal upgrade on any machine currently using a WPA with no modifications to mounting plates or couplings.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
