Description
WPWX Universal Dual Output Shaft Worm Gear Reducer — Mechanically Synchronised Bilateral Drive from a Single Universal-Mount Unit
When a wide conveyor needs both head-drum ends driven synchronously, or an agricultural spreader requires bilateral output from a single gearbox, the WPWX universal dual output shaft worm gear reducer delivers the solution. Both output shaft extensions (E₁ and E₂) are keyed to the same worm wheel — making bilateral speed equality a mechanical certainty, not an electronic control challenge.
The WPWX builds on the WPW universal flanged-base platform, inheriting the five mounting orientation capability and multi-face oil system while adding the extended housing required for dual output shaft bearings. The E, E₁, E₂ specification in the table defines the bilateral shaft geometry, confirming equal extensions on each side. Available in 12 sizes (40–250 mm), ratios 1/5–1/60, shaft directions A–C. एवर-पावर के बारे में | Request a Quote

Product Structure — Universal Housing with Bilateral Output Shaft
The WPWX extends the WPW housing laterally to accommodate additional bearing bores on both sides of the worm wheel shaft, creating equal-length output shaft extensions (E₁ and E₂) projecting symmetrically from the housing. Both extensions are keyed to the same worm wheel, providing mechanically exact bilateral synchronisation with zero backlash and zero electronic control requirement.
| Output Shafts | Two equal-length shafts both keyed to worm wheel — zero speed differential |
| Synchronisation | Mechanical lock — mathematically exact, no electronics required |
| Housing | FC25 cast iron; wider body for bilateral output bearing bores |
| Base | Universal flanged base; 4 anchor bolt positions; 3 shaft directions (A–C) |
| Gear Pair | 20CrMnTi worm (≥58 HRC) + ZCuSn10Pb1 bronze wheel |
| Self-Locking | At ratios ≥1/30 — applies simultaneously to both output shaft ends |
✅ Key Features & Benefits
Mechanically Exact Bilateral Synchronisation
Both output shaft ends rotate at precisely equal speed because both are keyed to the same worm wheel — no differential, no electronic control loop, no synchronisation chain backlash. For wide conveyors, bilateral spreader drives, and balanced bilateral machinery, this mechanical certainty is more reliable than any electronic synchronisation system. Keywords: dual output universal worm gear reducer, bilateral synchronised worm gearbox.
Universal Flanged Base — Mount in Any Orientation
The WPWX inherits the WPW universal flanged-base system with four anchor bolt positions and multi-face oil ports. Three standard shaft-direction positions (A–C) accommodate the bilateral output shaft geometry while maintaining the installation flexibility needed for varied machine layouts.
One Unit Replaces Gearbox + Synchronisation System
A WPWX replaces: (1) a single-output worm gearbox plus (2) a bilateral synchronisation drive (chain, belt, or servo pair). For wide conveyor and agricultural machinery where synchronisation chain drives at the output end add complexity and maintenance, the WPWX provides mechanically superior synchronisation with less BOM complexity.
Smooth Precision Drive — Consistent Bilateral Speed
Both gear surfaces are ground to ISO 1328 Grade 7 tolerances, providing smooth, uniform bilateral output free from gear-induced velocity variation. For wide belt conveyors and spreader equipment where bilateral speed inequality causes belt skew or uneven material distribution, this precision is important.
Bilateral Self-Locking at High Ratios
At ratios of 1/30 and above, the WPWX self-locks at both output shaft ends simultaneously — preventing bilateral back-driving under gravity or residual load forces when the motor is de-energised. This simultaneous bilateral locking is more reliable than two separate brakes on a conventional bilateral drive system.
12 Sizes — Complete Coverage
Twelve sizes (40–250 mm) with output torques up to 2,371 Nm combined bilateral (at 1500 r/min, size 250, 1/60 ratio) cover the full range of wide industrial conveyor, agricultural, and textile machinery bilateral drive requirements within the WPW universal series.

❓ Frequently Asked Questions
What is the difference between the WPWX and the WPW?
The WPW has a single output shaft on one side of the housing. The WPWX has two equal-length output shafts projecting symmetrically from both sides of the housing — both keyed to the same worm wheel for mechanically exact bilateral synchronisation. The WPW flanged base platform is unchanged between the two products.
How is the WPWX bilateral synchronisation different from using two WPW gearboxes?
A WPWX uses one worm wheel shared by both output shafts — providing mathematically exact speed equality with zero differential. Two separate WPW gearboxes driven by the same motor via a cross-shaft still have small manufacturing tolerances between the two gear pairs, which can produce minor bilateral speed differences. The WPWX’s single shared wheel eliminates this source of bilateral variation entirely.
Can the WPWX output shaft extensions be different lengths on each side?
Standard supply provides equal extensions (E₁ = E₂) as specified in the table. Custom asymmetric extensions where E₁ ≠ E₂ are available for OEM orders where the gearbox must be positioned off-centre between the two drive points. Contact us with your required E₁ and E₂ dimensions for a custom quotation.
What is the maximum combined output torque of the WPWX?
The combined output torque from both shaft ends must not exceed the rated output torque for the selected size and ratio. At 1500 r/min input, size 250 at ratio 1/60 delivers approximately 2,371 Nm combined — equivalent to approximately 1,186 Nm per shaft end under symmetric loading. Contact our engineers for a precise calculation for your motor power and ratio.
What shaft directions are available for the WPWX?
The WPWX supports three standard input shaft-direction positions (A, B, C). This is fewer than the standard WPW’s five positions because the wider housing required for the bilateral output bearing arrangement limits the available input shaft angles. The three available positions cover horizontal foot-mount and two common inclined configurations — contact us if your application requires a non-standard angle.
