WPWDKO \u2014 Double Keyed + Vertical Output Worm Gear Reducer<\/div>\n

WPWDKO: Double Keyed Shaft Ussk\u00e4igu reduktor<\/span> with Vertical Output<\/h2>\n

The WPWDKO combines two WP-series configuration features in one cast iron ussik\u00e4igu reduktor<\/strong>: double keyed shafts (DK = input and output shafts are both keyed at both ends, accepting sprockets, pulleys, or couplings on either side) and vertical output shaft orientation (O = output shaft pointing down). Frame sizes WP40\u2013250, ratios 10\u201360:1, power 0.12\u201315 kW, torque 17\u20133,000 N\u00b7m. 20CrMnTi worm shaft hardened to HRC 56\u201362, copper alloy worm wheel.<\/p>\n

What the WPWDKO Configuration Combines<\/h2>\n

The WPWDKO suffix breaks down as: WP (series) + W (worm) + D (double keyed) + K (keyed both sides) + O (vertical output shaft). In the WP ussik\u00e4igu reduktor<\/strong> family, this means:<\/p>\n

\n
\n

DK \u2014 Double Keyed Both Ends<\/strong><\/p>\n

Both the input worm shaft and the output shaft have keyways cut at both ends. This allows sprockets, chain wheels, belt pulleys, or couplings to be mounted at either end of both shafts \u2014 giving maximum flexibility for drive arrangement. Standard WP units are only keyed at the primary drive end of each shaft.<\/p>\n<\/div>\n

\n

O \u2014 Vertical Output Shaft<\/strong><\/p>\n

See ussik\u00e4igu reduktor<\/strong> output shaft is oriented vertically (shaft-down as standard, shaft-up on request). Combined with double keying, this enables a vertical chain or belt drive from a horizontal input motor \u2014 common in textile loom drives, elevator machinery, and vertical mixer shafts where a sprocket or pulley is needed on the vertical driven shaft.<\/p>\n<\/div>\n

\n

Combined Advantage<\/strong><\/p>\n

A single WPWDKO ussik\u00e4igu reduktor<\/strong> with both double keying and vertical output can drive a vertical chain directly from either side of the output shaft \u2014 giving installers freedom to route the drive chain to the left or right of the machine depending on the available clearance.<\/p>\n<\/div>\n<\/div>\n

\ud83d\udd11<\/div>\n

Keyway Both Ends \u2014 Drive Either Side<\/h3>\n

Double keyed shafts let the installer mount a sprocket, pulley, or coupling at either end of both the input and output shafts. This gives maximum layout flexibility \u2014 the drive can be routed left or right based on available clearance in the machine frame, without needing a different ussik\u00e4igu reduktor<\/strong> variant.<\/p>\n<\/div>\n

\n

Vertical Chain or Belt Drive<\/h3>\n

The vertical output shaft with keyway allows a chain wheel or belt pulley to be mounted directly on the vertical output shaft \u2014 driving equipment below the gearbox without a bevel diversion stage. This single WPWDKO ussik\u00e4igu reduktor<\/strong> replaces a horizontal unit plus bevel gearbox in vertical chain configurations.<\/p>\n<\/div>\n

\n
\ud83d\udd25<\/div>\n

HRC 56\u201362 Hardened Worm Shaft<\/h3>\n

The 20CrMnTi worm shaft is carburised, quenched, and precision ground to HRC 56\u201362 surface hardness \u2014 the same specification used in automotive transmission components. This worm shaft hardness level is what enables the high torque-to-size ratio of the WP-series ussik\u00e4igu reduktor<\/strong> across the full frame range.<\/p>\n<\/div>\n

\n
\ud83d\udd12<\/div>\n

Self-Locking Vertical Hold<\/h3>\n

Self-locking at \u2265 20:1 with the output shaft vertical means the driven equipment holds position when the motor stops \u2014 no separate brake needed for most vertical machinery positioning applications of this ussik\u00e4igu reduktor<\/strong>.<\/p>\n<\/div>\n<\/div>\n

FAQ \u2014 WPWDKO Double Keyed Vertical Worm Gear Reducer<\/h2>\n
\n
\n

What does “double keyed” mean in the WPWDKO designation?<\/h3>\n

Double keyed (DK) means that both shafts \u2014 input worm shaft and output shaft \u2014 have keyways cut at both ends (left end and right end of each shaft). This allows drive components such as sprockets, pulleys, or couplings to be mounted at either end of either shaft. In a standard WP ussik\u00e4igu reduktor<\/strong>, keyways are provided only at the primary drive ends. The double keying doubles the mounting options without changing the gear ratio or torque rating.<\/p>\n<\/div>\n

\n

Can I mount a chain sprocket directly on the vertical output shaft?<\/h3>\n

Yes \u2014 this is one of the primary application scenarios for the WPWDKO ussik\u00e4igu reduktor<\/strong>. The vertical output shaft keyway accommodates a standard chain sprocket. The keyway transmits torque to the sprocket; the shaft shoulder and a retaining plate or lock collar prevent axial movement. Provide the sprocket bore diameter, chain pitch, and required sprocket teeth count when contacting Korea Ever-Power for matched component confirmation.<\/p>\n<\/div>\n

\n

What is the difference between WPWDKO and WPWKO worm gear reducers?<\/h3>\n

Both have vertical output shafts. The key difference: WPWKO has a single keyed output shaft (one keyway, one end), designed for direct coupling or hollow bore installation. WPWDKO has double keyed shafts at both ends of both shafts \u2014 the vertical output can have sprockets or pulleys mounted at either end, and so can the input shaft. Choose WPWDKO when you need to run a vertical chain drive or belt drive from the output shaft, or need dual mounting positions on the input shaft of this ussik\u00e4igu reduktor<\/strong>.<\/p>\n<\/div>\n

\n

Why is the ratio range 10\u201360:1 rather than the full 10\u201360:1 of other WP series?<\/h3>\n

The standard WPWDKO ratio range is 10:1, 15:1, 20:1, 30:1, 40:1, 50:1, and 60:1. The upper limit of 60:1 reflects the practical limit of single-stage worm reduction in this housing size. If a higher ratio is needed, the WPEX double-stage ussik\u00e4igu reduktor<\/strong> provides ratios beyond 60:1 in a single housing. Contact Korea Ever-Power if intermediate non-standard ratios are required \u2014 availability varies by frame size.<\/p>\n<\/div>\n

\n

What worm wheel material is used in the WPWDKO?<\/h3>\n

The WPWDKO ussik\u00e4igu reduktor<\/strong> uses a Copper-9-4# alloy worm wheel \u2014 a tin-bronze-based copper alloy with 9% tin content, known for good load capacity, wear resistance against hardened steel worm shafts, and acceptable performance at the peripheral sliding speeds typical of this ratio and power range. This is the same alloy family used in standard WP-series units across the frame range.<\/p>\n<\/div>\n

\n

Is the WPWDKO worm gear reducer suitable for continuous 24-hour operation?<\/h3>\n

Yes, within the rated power and torque for the selected frame. For continuous duty at rated load, monitor oil sump temperature \u2014 maximum 95\u00b0C. For applications that approach rated power continuously (e.g. food processing lines, textile plant drives), ensure adequate ambient ventilation around the housing. If ambient temperature is above 40\u00b0C or the application runs at high continuous load near the maximum rating, specify synthetic ISO VG 220 lubricant and reduce oil change intervals to 1,500 hours.<\/p>\n<\/div>\n

\n

What documentation is available for the WPWDKO for OEM qualification?<\/h3>\n

Korea Ever-Power provides: 2D dimensional drawings (PDF or DWG), ISO 9001:2015 certificate copy, worm shaft material certificate (20CrMnTi with heat treatment data), and bearing brand documentation (C&U or customer-specified brand). For OEM qualification of this ussik\u00e4igu reduktor<\/strong>, contact sales@worm-reducers.xyz with your specific documentation requirements \u2014 delivery within 2 business days for standard items.<\/p>\n<\/div>\n<\/div>\n

“Used WPWDKO80 on a ceramic forming machine where the vertical chain drive sprocket needed to sit on the right side of the shaft.
