Gear Couplings
WGCII Crowned Gear Coupling
WGCII Crowned Gear Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
WGCII is the second WGC crowned-gear arrangement, with its own paired-bore, D/B/C and inertia pattern. It should not be treated as a simple size extension of WGCI: the exact table row and drawing establish the connection geometry, shaft spacing and permissible operating envelope. The published model tables contain 14 size rows and provide torque values spanning 0.71–160 N·m, permissible-speed values spanning 2300–7500 r/min, bore values spanning 12–260 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- WGCII-specific crowned-tooth dimensional pattern
- Paired bores and bore length by model
- Mass and inertia support acceleration and braking review
- The model data provides torque values spanning 0.71–160 N·m, permissible-speed values spanning 2300–7500 r/min, bore values spanning 12–260 mm for a traceable preliminary comparison.
Typical Selection Context
- Gear-unit and process drives using the WGCII interface
- Torque-transmission lines where shaft-end dimensions are asymmetric

Engineering Context
This model is best understood from its own construction: WGCII-specific crowned-tooth dimensional pattern; Paired bores and bore length by model; Mass and inertia support acceleration and braking review Industry selection practice checks torque and speed together with the movement, shaft interface, installation envelope and maintenance conditions allowed by that construction.
Technical Notes
- Model symbols, units and empty or placeholder cells are shown as published.
- Dimension letters must be interpreted with the relevant assembly drawing.
- Published values support preliminary review and do not replace final engineering confirmation.
Assembly Drawing
Information Required for Selection
- Verify WGCII bore pair and dimension symbols from the drawing
- Review torque, speed, lubrication, inertia and shaft spacing
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Can WGCI and WGCII share the same drawing?
No. Their dimension patterns are separate and the selected model drawing controls the interface.
What operating data is needed besides torque?
Include speed, starts, stops, displacement, lubrication conditions and available installation space.
Are the published values final ordering values?
No. They are preliminary engineering data; confirm the selected model, drawing, dimensions, materials, standard and suitability with RONGXING DRIVE.
Technical data is provided for preliminary selection. Confirm the final model, dimensions, materials, applicable standard and operating suitability with RONGXING DRIVE before quotation, manufacture or installation.
