WPWKT Universal Hollow Shaft Worm Gear Reducer \u2014 Coupling-Free Direct Shaft Drive Purpose-Built for Inclined Conveyor & Quarry Equipment<\/h1>\n

Inclined quarry conveyors, aggregate elevator head drives, and angled mining conveyor systems have two key drive requirements: the output shaft connection must be coupling-free (hollow bore directly onto the conveyor drum shaft) for compact, maintenance-free installation, AND the gearbox housing must be correctly configured for inclined service \u2014 with oil ports at the right positions and housing geometry suited to the angled mounting arrangement. The WPWKT universal hollow shaft tilted-base worm gear reducer<\/strong> delivers both in one purpose-built unit.<\/p>\n

The WPWKT extends the WPWT inclined housing geometry with an H7 hollow output bore (16\u2013110 mm) replacing the standard solid shaft \u2014 providing the compactness of coupling-free drum shaft engagement at inclined conveyor head and elevated transfer drive positions. Available in 12 sizes<\/strong>, ratios 1\/5\u20131\/60. About Ever-power<\/a> | Get an Inclined Drive Quote<\/a><\/p>\n<\/section>\n

The WPWKT integrates the WPWT inclined-service housing geometry (elongated LL body, inclined-position oil ports, five shaft-direction positions) with an H7 hollow bore replacing the standard solid shaft. The worm wheel shaft is through-bored to H7 and fitted with a keyway, allowing the driven drum shaft to slide directly in from the housing face at the required inclined angle.<\/p>\n\n\n\n\n\n\n\n

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

Hollow Bore + Inclined Housing \u2014 Coupling-Free at Any Angle<\/h3>\n

The WPWKT is the only product in the WPW series that combines H7 hollow bore output with an inclined-service housing configuration. WPWT has inclined housing but solid shaft; WPWK has hollow bore but horizontal-optimised housing. WPWKT delivers both \u2014 coupling-free drum shaft engagement in an inclined-service housing. Keywords: hollow shaft inclined mount worm reducer, coupling-free tilted conveyor worm gearbox.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Anti-Rollback Self-Locking on Inclined Conveyors<\/h3>\n

At ratios \u22651\/30, the WPWKT self-locks \u2014 preventing inclined conveyor belt and load rollback when the motor is de-energised. The hollow bore ensures the drum shaft is rigidly engaged when the self-locking holds the load. This combination is more reliable than a solid shaft with external backstop in many quarry and aggregate inclined conveyor applications.<\/p>\n<\/div>\n

\n
<\/div>\n

Oil Correctly Positioned for Inclined Service<\/h3>\n

The WPWKT oil ports are configured for the inclined operating position, ensuring correct gear mesh lubrication even when the housing is tilted. This prevents the high-end gear under-lubrication and low-end oil churning that occur when standard horizontal units are used in inclined service.<\/p>\n<\/div>\n

\n
<\/div>\n

Compact Inclined Hollow Shaft Drive \u2014 No Separate Backstop or Coupling<\/h3>\n

The WPWKT eliminates both the output coupling (hollow bore) and the separate mechanical backstop (self-locking worm) from the inclined conveyor head drive arrangement. One product replaces two mechanical components, reducing the total drive assembly height at the conveyor head \u2014 important in space-constrained quarry and mining conveyor structures.<\/p>\n<\/div>\n

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

Precision Gear Pair for Smooth Inclined Operation<\/h3>\n

Ground worm and bronze wheel to ISO 1328 Grade 7 provide smooth, quiet output in the inclined position \u2014 minimising belt vibration and ensuring consistent conveyor speed even at steep incline angles where belt tension variations can amplify gear-induced velocity variations.<\/p>\n<\/div>\n

\n
<\/div>\n

12 Sizes \u2014 Complete Inclined Hollow Drive Range<\/h3>\n

Twelve sizes covering hollow bore 16\u2013110 mm and output torques up to 2,371 Nm provide the complete range of inclined hollow shaft conveyor, aggregate, and mining drive requirements within the WPWKT product.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
