Product Overview and Application Boundary

A universal joint coupling is usually composed of yokes, cross-bearing assemblies, flanges, bearing components and, when required, a spline telescopic section. It transmits torque where shafts operate with larger working angles or longer distances. It is used on rolling mill main drives, straighteners, cranes, heavy conveyors and shaft systems with changing installation positions. Compared with ordinary couplings, it places more emphasis on working angle, telescopic movement, balancing, lubrication and cross-bearing life. Selection should confirm torque, speed, working angle, flange connection, telescopic length, axial movement and maintenance space.

Typical use

Recommended for rolling mill main drives, straighteners and long-distance shafting.

Selection focus

Confirm torque, speed, shaft diameter, keyway, service factor, misalignment and working environment before selection.

Custom options

Bore, keyway, material, heat treatment, dynamic balancing, surface treatment and export packing can be customized.

Material and inspection

Common materials include 45 steel, 42CrMo or project-specified grades; inspection records can be supplied on request.

Manufacturing Control

Machining, Heat Treatment and Inspection Process for Universal Joint Coupling

This route follows Universal Joint Coupling from drawing and material review through blank preparation, CNC rough machining, feature machining, heat treatment, reinspection, finish machining, assembly and final release. The approved drawing determines the exact material and treatment route.

Manufacturing and inspection flowchart for Universal Joint Coupling
Typical machining and heat-treatment route for Universal Joint Coupling; drawing-specific operations are released only after technical approval.
  1. 01. Drive data and drawing review: Confirm torque, speed, shaft interfaces, alignment allowance, acceptance criteria and the approved drawing before release.
  2. 02. Material certificate and blank inspection: Verify material identity, certificate, heat number, blank dimensions and the specified forging, casting or bar-stock route.
  3. 03. Saw cutting and forging/casting blank preparation: Saw-cut the stock or prepare the forging/casting blank, remove scale, transfer traceability marks and retain machining allowance.
  4. 04. CNC rough turning of faces, diameters and bores: Use CNC or vertical lathes to rough-turn faces, outside diameters, bores and datum shoulders, leaving allowance for heat-treatment distortion and finishing.
  5. 05. Yoke/flange machining and spline milling/broaching: Machine the named teeth, grooves, holes, splines or mechanism features by turning, milling, hobbing, shaping, drilling, boring or grinding as specified.
  6. 06. Cross-journal turning and bearing-component preparation: Manufacture or verify the spring, pin, bearing, friction or elastomer element to the released specification, with batch traceability where required.
  7. 07. Yoke Q&T and cross-journal surface hardening: Quench and temper yokes or splined shafts and harden cross-journal bearing tracks by the approved induction or case-hardening route, followed by tempering.
  8. 08. Hardness, distortion and NDT reinspection: Check hardness, effective case where applicable, distortion and surface condition; perform UT, MT or PT when required before final machining.
  9. 09. Bore, keyway and fit finishing: Finish-turn or grind datum faces and fits, then bore the shaft holes and machine keyways, splines, seal seats or mounting interfaces to the approved tolerances.
  10. 10. Articulation, runout and assembly inspection: Verify dimensions, runout, tooth or component fit and controlled assembly; record lubrication, fastener, balance or functional checks applicable to the product.
  11. 11. Final inspection, marking and release: Complete final inspection, traceability marking, rust protection and packing only after the required records and acceptance results are complete.

FAQ

Product Selection FAQ

Can the Universal Joint Coupling be customized from a drawing or old part?

Yes. We can confirm bore, keyway, material, heat treatment, balancing grade, surface treatment and export packing by drawing or old part photos.

What information is needed before quotation?

Please send torque or motor power, speed, shaft diameter, keyway, equipment type, working condition, quantity, drawings or old coupling photos.

Can it replace an imported coupling brand?

Replacement is evaluated after checking dimensions, torque, material, installation space and working condition. Final drawings should be confirmed before production.

What applications are a good fit for the Universal Joint Coupling?

Recommended for rolling mill main drives, straighteners and long-distance shafting.

What should be checked during installation and maintenance?

Check operating angle, yoke phasing, flange or shaft fit, bolt tightening and spline lubrication where applicable. Inspect universal joints, splines and fasteners for wear, play and lubricant loss.
