WPWS Universal Speed Worm Gear Reducer with Cooling Fins \u2014 Thermally Stable Multi-Orientation Drive for Cement, Mining & Continuous Industrial Applications<\/h1>\n

The WPW universal flanged-base gearbox excels in versatile installation applications \u2014 but in continuous heavy-duty service, particularly in hot industrial environments, the worm gear thermal load can push oil sump temperatures toward the 95\u00b0C operating limit, reducing lubricant life and risking overtemperature trips. The WPWS universal speed worm gear reducer with cooling fins<\/strong> resolves this by integrating cast-in longitudinal cooling fins on the WPW housing, providing approximately 15\u00b0C lower sustained oil temperature<\/strong> than the smooth-body WPW at rated load.<\/p>\n

The WPWS maintains all the installation advantages of the WPW platform \u2014 integral flanged base, five mounting orientations, multi-face oil ports \u2014 while adding the thermal resilience needed for cement plant conveyor drives, mining equipment auxiliaries, and outdoor industrial equipment in hot climate regions. Available in 12 sizes<\/strong> (40\u2013250 mm), ratios 1\/5\u20131\/60. About Ever-power<\/a> | Request Thermal Assessment<\/a><\/p>\n<\/section>\n

\"WPWS<\/div>\n

The WPWS extends the WPW flanged-base housing with cast-integral longitudinal cooling fins on the housing top and outer side faces. The fins are part of the same foundry casting as the housing body \u2014 permanent, with no risk of loosening or separation under the vibration and thermal cycling of industrial environments.

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

~15\u00b0C Lower Temperature for Continuous Heavy-Duty Service<\/h3>\n

The WPWS fin array maintains oil sump temperature approximately 15\u00b0C lower than the WPW smooth-body at rated load. In cement plants, outdoor mining equipment, and tropical industrial environments where ambient temperatures reach 40\u201345\u00b0C, this margin is often the difference between stable continuous operation and recurring overtemperature stops. Keywords: universal worm reducer cooling fins, thermal stability flanged-base worm gearbox.<\/em><\/p>\n<\/div>\n<\/div>\n

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

Permanent Fins for Industrial Environments<\/h3>\n

The cast-integral fins cannot loosen, corrode away, or separate under the vibration and thermal cycling of cement plants, mining sites, and heavy outdoor equipment. Unlike bolt-on thermal accessories, the WPWS thermal performance is consistent throughout the entire service life with no maintenance required for the fin system.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Full Universal Platform \u2014 All Five Orientations<\/h3>\n

The WPWS retains all five mounting orientations of the WPW platform. The fin array is positioned to maximise natural convection in the most common (horizontal) orientation, with adequate performance in all other rated positions. Correct fin orientation relative to air flow direction should be confirmed for each installation \u2014 contact us for guidance.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Extended Lubricant Life in Continuous Applications<\/h3>\n

Reducing oil sump temperature by 15\u00b0C approximately doubles lubricant oxidation life. In continuous industrial applications (cement kilns, mining conveyors, chemical plant drives) the WPWS can extend drain intervals from the standard 2,500 hours to 3,500\u20134,500+ hours, reducing maintenance stops and lubricant consumption.<\/p>\n<\/div>\n<\/div>\n

\n
\u2b06\ufe0f<\/div>\n
\n

Direct Thermal Upgrade from WPW<\/h3>\n

The WPWS base footprint (A, AB, B, BB, AC, BC, CC dimensions) and shaft dimensions are identical to the WPW. Where an installed WPW is experiencing overtemperature issues, the WPWS is the minimum-disruption upgrade \u2014 verify HL height clearance and swap in place.<\/p>\n<\/div>\n<\/div>\n

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

Same Precision Gearing \u2014 No Performance Trade-Off<\/h3>\n

The WPWS uses the same 20CrMnTi worm and ZCuSn10Pb1 bronze wheel pair as the WPW. The fins add thermal performance without any change to gear mesh geometry, transmission efficiency, noise level, or output torque capacity.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

\ufe0f Thermal Stability Run Test<\/h3>\n

Each WPWS undergoes a 60-minute thermal stability run<\/strong> at 110% rated torque with oil sump temperature measured at stabilisation. Temperature must remain below 90\u00b0C \u2014 providing 5\u00b0C safety margin below the 95\u00b0C maximum. This test confirms the fin array is delivering its rated thermal benefit on every unit before shipment.<\/p>\n<\/div>\n
