TS7Z110\u00d7160 Locking Assembly \u2013 110mm Shaft 160mm OD Keyless Rigid Shaft-Hub Connector<\/h1>\n

The largest model in the TS7Z series, the TS7Z110\u00d7160<\/strong> delivers 7.2 kN\u00b7m rated torque and 180 kN axial force capacity for 110 mm shaft connections at the heaviest end of the locking assembly range. At 10.4 kg mass and M_a = 145 N\u00b7m, installation requires a calibrated torque multiplier. Applications include large mine hoists, primary mill drives, and major industrial compressors where shaft size and power level define the design. For a complete listing of all TS7Z locking assembly models, visit our product catalog<\/a>.<\/p>\n

The TS7Z locking assembly operates on the principle of tapered ring compression: two tapered steel rings \u2014 inner and outer \u2014 are drawn together axially by the clamping screws. The taper geometry converts axial screw preload into a radial clamping force, expanding the inner ring against the shaft surface and contracting the outer ring against the hub bore simultaneously. The resulting surface pressure \u2014 65 MPa for the TS7Z110\u00d7160 at the specified M_a of 145 N\u00b7m \u2014 generates a friction connection that transmits both torque (Mt = 7.2 kN\u00b7m) and axial force (Ft = 180 kN) without any mechanical interlock element. No keyway is required in either the shaft or the hub bore.<\/p>\n

The elimination of the keyway is the principal engineering advantage of the TS7Z over traditional keyed hub connections. A keyway introduces a stress concentration at its corners that can initiate fatigue cracks under the cyclic torsion loading of a rotating drive \u2014 particularly at high surface hardness or in applications with frequent torque reversals. The TS7Z distributes torque loading uniformly around the full circumference of the shaft bore, eliminating this stress riser and significantly extending the fatigue life of the connected shafts. For high-cycle, high-torque drives \u2014 mills, fans, compressors, and crushers \u2014 this durability improvement is a primary selection rationale.<\/p>\n

Installation and Design Guidance<\/h2>\n

\"TS7Z110\u00d7160<\/p>\n

Installation of the TS7Z110\u00d7160 requires the shaft surface to be clean, dry, and within an h6 or k6 shaft tolerance, with a surface finish of Ra 0.8\u20131.6 \u03bcm. The hub bore should be machined to H7 tolerance. Clamping screw threads and head bearing faces must be lubricated with MoS\u2082 paste before installation to ensure the M_a = 145 N\u00b7m tightening torque produces the correct clamping force. Tighten all screws in a star pattern in at least three progressive passes \u2014 do not fully tighten one screw before the others.<\/p>\n

To verify shaft material suitability, check: Ps (65 MPa) \u2264 0.9 \u00d7 shaft yield strength. For C45 steel (yield ~370 MPa): 0.9 \u00d7 370 = 333 MPa > 65 MPa \u2014 acceptable. For aluminium alloy 6061-T6 (yield ~275 MPa): 0.9 \u00d7 275 = 247 MPa; compare with 65 MPa for this model. If the shaft material yield strength is insufficient, contact our contact our team<\/a> for a re-rated configuration.<\/p>\n

Keyless Design<\/h3>\n

No keyway in shaft or hub. Eliminates keyway stress concentration and fretting wear. Angular position can be set freely \u2014 no keyway angular constraint.<\/p>\n<\/div>\n

\n

Self-Releasing Disassembly<\/h3>\n

Back off clamping screws in a star pattern \u2014 the taper geometry produces a self-releasing action requiring no extraction tools or heat. Shaft and hub surfaces are undamaged after removal.<\/p>\n<\/div>\n

\n

Uniform Load Distribution<\/h3>\n

Torque is transmitted through friction uniformly around the full shaft circumference, distributing stress evenly and enabling the same torque to be carried at lower peak shaft stress than a keyed connection.<\/p>\n<\/div>\n

\n

Bidirectional Torque<\/h3>\n

Frictional connection transmits equal torque in both rotational directions. No directional constraint \u2014 suitable for reversing drive applications without additional design consideration.<\/p>\n<\/div>\n<\/div>\n

Egypt \u2014 Industrial Gearbox OEM<\/p>\n

We use the TS7Z110\u00d7160 for output shaft connections on our range of industrial helical and bevel-helical gearboxes. The locking assembly is offered as a standard shaft termination option because it allows the gearbox to be mounted on a plain shaft without machining a keyway \u2014 simplifying customer installation.<\/p>\n

We specified the TS7Z110\u00d7160 for main drive shaft connections on our 72 MW wind turbine gearbox housings. The locking assembly design allows precise torque setting during installation and the published Ft and Mt values aligned exactly with our shaft end-force calculations. We have installed over 60 units across three turbine models with no field failures.<\/p>\n

Brazil \u2014 Steel Rolling Mill<\/p>\n

Fitted the TS7Z110\u00d7160 on hot strip mill coiler mandrel drive connections. Temperature in this area reaches 60\u00b0C; the locking assembly’s static friction connection is unaffected by thermal cycling where a keyed connection would develop fretting wear over time. The 65 MPa contact pressure distributes the load evenly around the shaft circumference.<\/p>\n
