WPEX Double Speed Cast Iron Worm Reducer — Product Overview
그만큼 WPEX is the double-stage counterpart to the single-stage WPX: X-type vertical downward output for ceiling and inverted installations, extended to ratios 1/200–1/900+ by the dual worm stage architecture. Overhead mining conveyor drives running below 5 rpm, sub-floor mechanism drives, and ceiling-mounted gravity-assist systems requiring extreme ratios use WPEX where no single-stage overhead reducer can deliver the required output speed.

WPEX Double Speed Worm Reducer — Core Features
■ X-Type Downward Output + Double Stage — Extreme Ratio Ceiling Drive
The WPEX combines X-type vertical downward output with two-stage extreme ratio reduction — providing ratios 1/200 to 1/900+ in a ceiling-mount or inverted installation. Applications requiring output speeds below 10 rpm from an overhead drive unit use WPEX where a single-stage WPX would only reach 1/60.
■ Same 6,050 Nm Output Torque as WPEA
X-type output does not affect dual-stage torque capacity. WPEX size 155–250 delivers 6,050 Nm.
■ Oil Circuit for X-Type Inverted/Downward Orientation
Both chamber oil volumes are adjusted for X-type inverted orientation. Use the WPEX lubrication table for correct volumes in ceiling/inverted mounting.
■ Bilateral Horizontal Input — Motor from Either Side
Horizontal bilateral input shaft retained in X-type configuration — motor connects from either side of the ceiling-mounted housing.
■ FC20+ Dual-Chamber Cast Iron — Inverted Load Stability
Cast iron housing maintains dimensional stability under the sustained inverted load of ceiling-mount installation. Dual-chamber design maintains inter-stage alignment at operating temperature.
■ Independent Oil Chambers — Both Stages
Two independent sealed chambers with separate fill, gauge, and drain — each maintained independently on 2,500-hour intervals.
WPEX Worm Reducer — Industry Applications
⚊ Overhead Mining Conveyor Slow Drives
WPEX ceiling-mount with X-type downward output drives mining conveyor head shafts at ultra-slow speeds (below 5 rpm) directly from a standard motor — eliminating the VFD that single-stage ceiling drives require for comparable speeds.
⚒ Sub-Floor Mechanism Drives
Extreme-ratio ceiling-mounted drives for sub-floor conveyor mechanisms and under-floor turntable drives use WPEX downward output shaft to reach the driven equipment below the mounting structure.
☵ Ceiling-Mounted Gravity-Feed Controls
Overhead X-type slow drive for gravity-feed gate and hopper control mechanisms requiring ultra-slow, high-torque operation from a compact ceiling-mount unit.
⚛ Overhead Process Line Positioning
Industrial positioning systems requiring ceiling-mount drive units at extreme ratios for indexing, scanning, and inspection system overhead drives use WPEX for the combination of inverted mounting and extreme ratio.

WPEX Double Speed Worm Reducer — Customer Reviews
“WPEX ceiling-mounted on our mining conveyor overhead drives. X-type downward output shaft connects directly to the conveyor head shaft below. 1/600 ratio from a standard motor — no VFD needed.”
“Used WPEX on sub-floor conveyor mechanism drives. Double-stage at 1/500 with downward output shaft through the floor structure. Clean installation with no external coupling below the mounting frame.”
“WPEX on our ceiling-mounted gravity feed gate drives. 1/800 ratio, 2,100 Nm output, vertical downward shaft to the gate mechanism. Reliable slow-speed control from a compact overhead unit.”
“Good double-stage inverted drive. WPEX-80–135 on our overhead process line indexing drives. Extreme ratio, vertical downward output, correct torque. Would appreciate D-split maintenance access variant.”
