WPWDKA Flange-Mounted Universal Hollow Shaft Worm Gear Reducer \u2014 Three Interfaces, Zero Couplings, Maximum Output Direction Flexibility<\/h1>\n

The WPWDKA<\/strong> is the most feature-complete standard product in the WPW motor-direct hollow shaft family \u2014 integrating IEC motor flange (no input coupling), H7 hollow output bore (no output coupling), extended multi-direction output shaft geometry, AND the WPW universal flanged base. Four features in one casting: motor-direct input, coupling-free hollow bore output, extended multi-direction output reach, and multi-orientation universal base.<\/p>\n

Where the WPWDK delivers zero-coupling simplicity in a standard compact housing, the WPWDKA extends the output shaft (LL, M, N, E, F, G dimensions) to accommodate the varied-angle agitator heads, agricultural shaft connections, and off-axis driven equipment that the WPWDK standard housing cannot reach. Motors 0.12\u201315 kW, bore 18\u2013110 mm, ratios 1\/5\u20131\/60. About Ever-power<\/a> | Request a Configuration Review<\/a><\/p>\n<\/section>\n

Product Structure \u2014 Four Features in One Casting<\/h2>\n
\n
\"WPWDKA<\/div>\n
\n

The WPWDKA is the integration of WPWDK (motor-direct + hollow bore) with WPWDA (extended multi-direction output). IEC flange at the motor end; extended housing body (LL, M, N, E, F, G) supporting the hollow bore output at varied angles; WPW flanged base for universal mounting. The result is the maximum-flexibility motor-direct hollow shaft product in the WPW series.<\/p>\n\n\n\n\n\n\n\n

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

Maximum Feature Integration in the WPW DK Series<\/h3>\n

The WPWDKA is the only WPW product simultaneously providing: no input coupling (IEC flange) + no output coupling (hollow bore) + extended multi-direction output reach (LL body) + multi-orientation base (universal flange). For OEM machine builders who need all four capabilities in one product number, the WPWDKA is the single answer. Keywords: motor-direct hollow shaft multi-direction universal worm reducer, four-feature zero-coupling worm gearbox.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Extended Output for Long-Reach Agitator & Shaft Connections<\/h3>\n

The extended LL dimension and E, F, G output geometry provide the structural reach needed to connect to deep vessel agitators, tall agricultural auger heads, and elevated machine shafts at varied angles \u2014 where the compact WPWDK standard housing cannot span the required distance to the driven shaft connection point.<\/p>\n<\/div>\n

\n
<\/div>\n

15-Minute Motor Swap in Any Installation<\/h3>\n

IEC flange motor access is consistent regardless of how the hollow bore output is positioned \u2014 motors can be swapped in under 15 minutes even in installations where the output shaft connection is at a complex angle.<\/p>\n<\/div>\n

\n
<\/div>\n

One Product \u2014 All Motor-Direct Hollow Shaft Scenarios<\/h3>\n

By combining all four features, the WPWDKA eliminates the need to select between WPWDK (no extended reach), WPWDKO (multi-direction but no IEC flange+hollow bore), or WPWDA (extended reach but solid shaft) for complex motor-direct hollow shaft multi-direction applications.<\/p>\n<\/div>\n

\n
\u2697\ufe0f<\/div>\n

Precision Hollow Bore for Agitator Shaft Service<\/h3>\n

H7 hollow bore ground to precision (\u22640.05 mm concentricity TIR) ensures smooth, vibration-free engagement of agitator shafts \u2014 eliminating bore eccentricity as a source of agitator vibration in chemical, food, and pharmaceutical vessel drives.<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking Load Holding in Any Orientation<\/h3>\n

At ratios \u22651\/30, the WPWDKA self-locks in all orientations, including the extended-output configurations \u2014 providing passive load holding for agitators and elevated equipment regardless of output shaft direction.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Industry Applications<\/h2>\n
