WPWEDK Flange-Mounted Universal Hollow Shaft Double Speed Worm Gear Reducer \u2014 Zero Couplings at Both Ends with 1\/200\u20131\/900 Ultra-High Ratio on Universal Mounting Platform<\/h1>\n

Precision slow drives \u2014 textiles, paper, packaging, and material handling systems requiring output speeds below 10 r\/min from a 1500 r\/min motor \u2014 face a compound challenge: a two-stage reducer is needed for the high ratio, yet the application also benefits from zero coupling hardware at both the motor and driven shaft interfaces. The WPWEDK flange-mounted universal hollow shaft double speed worm gear reducer<\/strong> resolves this by integrating IEC motor flange, H7 hollow output bore, two-stage worm cascade (1\/200\u20131\/900), and WPW universal flanged base in one FC25 cast iron housing.<\/p>\n

The result is the most compact zero-coupling ultra-high ratio drive available on the WPW universal platform: motor + WPWEDK + driven shaft, three components, zero couplings, ratios from 1\/200 to 1\/900. Motors 0.12\u20135.5 kW, bore 30\u2013110 mm, 9 size groups. \u090f\u0935\u0930-\u092a\u093e\u0935\u0930 \u0915\u0947 \u092c\u093e\u0930\u0947 \u092e\u0947\u0902<\/a> | Request a Ratio Selection Guide<\/a><\/p>\n<\/section>\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
\u26a1<\/div>\n

Zero Couplings at Both Ends \u2014 with 1\/200\u20131\/900 Ultra-High Ratio<\/h3>\n

No single-stage product can achieve these ratios. No other WPWE double-speed product simultaneously provides IEC motor direct AND hollow bore output AND universal base. The WPWEDK delivers three zero-coupling features (IEC flange + hollow bore + universal multi-orientation base) AND the two-stage cascade in one housing. Keywords: IEC flange hollow shaft double speed worm reducer, zero-coupling ultra-high ratio worm gearbox.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Universal Flanged Base \u2014 Any Orientation at 1\/200\u20131\/900<\/h3>\n

The WPW universal flanged base allows the WPWEDK to be mounted at any supported orientation even at extreme 1\/900 output speeds \u2014 where reaction torques from the two-stage output are at their maximum and the flanged base rigidity is most valuable for preventing bolt loosening in sustained service.<\/p>\n<\/div>\n

\n
<\/div>\n

IEC Motor Swap at Ultra-High Ratio Drives<\/h3>\n

At 1\/900 ratio and 1500 r\/min input, output speed is just 1.67 r\/min. Maintenance access to the motor is critical in slow precision drives. The IEC flange enables motor replacement without disturbing the hollow bore shaft connection \u2014 maintaining the driven equipment position precisely during the motor swap.<\/p>\n<\/div>\n

\n
<\/div>\n

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

At combined ratios \u22651\/400, the two-stage WPWEDK provides extremely strong static self-locking \u2014 securing connected loads against gravity reversal, residual tension forces, or process pressure when the motor is de-energised. The hollow bore ensures the driven shaft is rigidly held while self-locking acts.<\/p>\n<\/div>\n

\n
<\/div>\n

Precision Slow Drives for Textile & Paper<\/h3>\n

At 1500 r\/min input and ratio 1\/900, output is 1.67 r\/min \u2014 enabling very precise slow rotation control for textile winding, paper web tension, and inspection machinery where gear-to-gear ratio stability (not just motor speed control) is the primary precision mechanism.<\/p>\n<\/div>\n
