Product Overview and Application Boundary

A drum gear coupling consists of two crowned external gear sleeves and a pair of straight internal gear rings. Torque is transmitted through internal and external gear meshing, while the crowned sleeve can swing inside the internal gear ring to compensate angular, axial and radial misalignment between shafts. The crowned tooth profile improves tooth contact, giving the coupling high torque capacity, large angular displacement, smooth transmission, high efficiency and long service life. It is widely used in metallurgical machinery, heavy machinery, mining equipment, cranes and conveying systems.

Typical use

Recommended for steel rolling mills, cranes, mining drives and port handling equipment.

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 Drum Gear Coupling

This route follows Drum Gear 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 Drum Gear Coupling — Typical machining and heat-treatment route for Drum Gear Coupling; drawing-specific operations are released only after technical approval.

01. Drive data and drawing review: Confirm torque, speed, shaft interfaces, alignment allowance, acceptance criteria and the approved drawing before release.
02. Material certificate and blank inspection: Verify material identity, certificate, heat number, blank dimensions and the specified forging, casting or bar-stock route.
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.
04. CNC rough turning of hubs and sleeves: Use CNC or vertical lathes to rough-turn faces, outside diameters, bores and datum shoulders, leaving allowance for heat-treatment distortion and finishing.
05. Hobbing/shaping crowned and mating gear teeth: Machine the named teeth, grooves, holes, splines or mechanism features by turning, milling, hobbing, shaping, drilling, boring or grinding as specified.
06. Pre-heat-treatment dimensions, allowance and datum inspection: Before heat treatment, record datum dimensions, tooth thickness, hole position, machining allowance and visible-defect inspection results for distortion control.
07. Normalizing/Q&T and tooth-surface hardening to drawing: Normalize or quench-and-temper the gear blanks as specified. If tooth-surface strengthening is required, apply the approved induction hardening, carburizing or nitriding route, followed by tempering and batch records.
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.
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. Tooth contact, 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. 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 Drum Gear 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 Drum Gear Coupling?

Recommended for steel rolling mills, cranes, mining drives and port handling equipment.

What should be checked during installation and maintenance?

Check shaft alignment, bore and keyway fit, fastener tightening, seals and the specified lubrication condition. Reinspect tooth contact, lubricant condition and abnormal noise during planned maintenance.
