WPS Configuration and Selection
The WPS model combines a side-mounted input shaft with a solid output shaft for general-purpose right-angle drives. It is suited to projects where a separate input coupling is preferred and the output shaft connects directly to the driven machine.
How does WPS differ from WPA?
WPS uses a side input-shaft configuration, while WPA is the basic foot-mounted WP configuration shown with motor-flange dimensional data. Select by comparing the input arrangement, mounting interface, and required shaft dimensions.
Which dimensions must be confirmed?
Check the size, ratio, input shaft, output shaft, center height, mounting holes, and available installation envelope against the parameter table.
What should be included in an inquiry?
Provide the required ratio, input speed, motor power, load type, mounting position, shaft dimensions, quantity, and working environment.
Explore related worm gearboxes or contact ZPGear with the required ratio, motor power, mounting position, and output-shaft dimensions for model confirmation.
Engineering Data and Selection Verification
Use the information on this WPS Industrial Worm Gearbox page for preliminary comparison. Final dimensions, materials, interfaces and operating limits must be confirmed against the current manufacturer catalog or an approved project drawing before purchase, fabrication or installation.
Table scope: each parameter row applies only to the model or size identified in that row. Do not interpolate, combine or transfer values between sizes without manufacturer confirmation.
Required Project Inputs
- Input speed and motor information
- Required output speed or target ratio
- Driven load type, start-stop pattern and operating schedule
- Mounting position, shaft direction and available installation space
- Site environment and maintenance-access requirements
Interfaces to Confirm
- Model size and mounting-hole pattern
- Input and output shaft or bore dimensions
- Flange, keyway, coupling and guarding arrangement
- Shaft center position and surrounding clearance
- Lubrication and inspection access
Reproducible Speed and Ratio Check
Required ratio: input speed ÷ target output speed. Expected output speed: input speed ÷ selected ratio. Record the source of each input value and use consistent units.
This arithmetic check does not confirm torque, power, service factor, temperature, efficiency or life. Ask ZPGear to verify those items from the current manufacturer data for the selected model and operating condition.
Source record: keep the manufacturer name, catalog or drawing number, revision date, selected model size, project inputs and final approval sheet with the order documentation. Send the project information to ZPGear for confirmation.
