Applications

Where Universal Worm Gearboxes Are Used

The key advantage of the WPW universal series is installation flexibility — the same gearbox unit installs in any orientation, simplifying machine design and spare parts management.

🔄

Multi-Orientation Machine Frames

Equipment where the gearbox orientation changes between machine variants, or where the drive axis is not horizontal. WPW eliminates the need to stock P-type and D-type separately. One model covers all orientations.

WPW / WPWDAny axis orientation

🤖

Automated Production Lines

Rotary indexing tables, transfer systems, and multi-axis automation where the gearbox may be mounted at any angle relative to the driven axis. WPW simplifies BOM across a product family with different drive configurations.

WPWKO / WPWKTAny mount · Hollow bore

⚙

Packaging and Filling Machines

Compact filling stations, capping heads, and label applicators where installation space constraints change the gearbox orientation between machine generations. Single model covers all orientations.

🏭

Heavy Industrial Drives

Rotary kilns, large mixers, and material handling equipment. WPWDK double-stage universal delivers 13,560 N·m at ratio 1:3,600 from a single multi-position housing — no second gearbox needed.

WPWDK 175–25013,560 N·m max

🛤

Conveyor Drive Standardisation

Fleet operators standardising on a single gearbox model across multiple conveyor orientations (horizontal, inclined, declined, vertical). WPW reduces spare part SKUs from 4 to 1.

📋

OEM Machine Builders

Machine builders supplying the same machine to customers in different countries with different motor standards. WPWD IEC universal accepts B5 and B14 motors in any frame size. Single gearbox model covers all motor configurations.

How It Works

Universal Housing — What Makes It Different

The WPW series uses a symmetrical housing design with oil fill points and breathers on multiple faces, allowing full lubrication in any mounting orientation.

Symmetrical housing design

The WPW housing is designed symmetrically with oil fill plugs, drain plugs, and breather vents on all four sides. The correct plug combination is selected at order based on the specified mounting orientation.

Same internal worm assembly

All WPW models use the same 20CrMnTi worm shaft (HRC 58–62) and ZCuSn10Pb1 bronze worm wheel as the P-type WPA and D-type WPDA. Performance data is identical regardless of mounting orientation.

Oil fill adjusted per orientation

Oil quantity and fill point differ by orientation. EVER-POWER ships the unit pre-filled for the specified orientation. When orientation changes in the field, the oil must be re-filled to the correct level for the new orientation.

Double-stage variant (WPWDK)

The WPWDK series adds a second worm stage inside the same universal housing. Combined ratios of 1:200 to 1:3,600 and torques up to 13,560 N·m — the highest in the WP series — in a multi-position housing.

Frequently Asked Questions

01 What is a universal worm gearbox? +

A universal worm gearbox (WPW series) uses a symmetrical multi-face housing that allows installation in any mounting orientation — horizontal, vertical, inverted, or wall-mounted — without changing the unit. Oil fill points and breather vents are provided on all housing faces; the correct plug combination is set at manufacture for the specified orientation.

02 What is the maximum torque of the WPW series? +

Single-stage WPW models deliver up to 3,025 N·m at size 250. The double-stage WPWDK series reaches 13,560 N·m at size 200–250 — the highest output torque in the entire WP worm gearbox range. Contact EVER-POWER to confirm the correct size for your required torque.

03 How does the universal housing differ from P-type and D-type? +

P-type (WPA, WPDA…) and D-type are optimised for specific orientations (foot mount or IEC flange). The WPW universal housing is symmetrical and includes oil plugs on all four sides, allowing any orientation. The internal worm shaft and bronze wheel assembly is identical to P-type and D-type WP models of the same size.

04 Can I change the mounting orientation after installation? +

Yes, but the oil must be re-filled to the correct level for the new orientation. EVER-POWER provides orientation-specific oil fill quantities for all WPW sizes. The housing does not need to be modified — only the active oil plug positions and fill quantity change.

05 What is the MOQ and lead time? +

Standard configurations: MOQ 10 pieces. Sample units in 15–25 days. Production orders 30–45 days. Non-standard ratios, shaft dimensions, hollow bore sizes, and keyway configurations are accepted as OEM options.

06 Are dimensional drawings available for all 19 configurations? +

2D DXF and PDF dimensional drawings for all standard WPW sizes and configurations are available within 24 hours at no charge. STEP 3D CAD files are available from 60 mm centre distance upward. Request by sending the series code, size, ratio, and mounting orientation to [email protected].
