TS7Z16\u00d745 Locking Assembly \u2013 16mm Shaft 45mm OD Keyless Rigid Shaft-Hub Connector<\/h1>\n

The TS7Z16\u00d745<\/strong> addresses the 16 mm shaft size common in compact industrial motors, agitator drives, and light gearbox applications. The 45 mm outer diameter fits within the confined hub geometries typical of compact drives in this shaft class, and the 119 MPa surface pressure \u2014 the highest in the TS7Z series \u2014 is easily supported by standard carbon steel shaft materials. 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 119 MPa for the TS7Z16\u00d745 at the specified M_a of 17 N\u00b7m \u2014 generates a friction connection that transmits both torque (Mt = 0.134 kN\u00b7m) and axial force (Ft = 16.8 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

\"TS7Z16\u00d745<\/p>\n

Installation of the TS7Z16\u00d745 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 = 17 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 (119 MPa) \u2264 0.9 \u00d7 shaft yield strength. For C45 steel (yield ~370 MPa): 0.9 \u00d7 370 = 333 MPa > 119 MPa \u2014 acceptable. For aluminium alloy 6061-T6 (yield ~275 MPa): 0.9 \u00d7 275 = 247 MPa; compare with 119 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

United Kingdom \u2014 Paper Mill Equipment<\/p>\n

We use the TS7Z16\u00d745 in our paper machine dryer section drive connections. The locking assembly provided a repeatable, calibrated installation that eliminated the variability we saw with previous keyway connections. The 0.134 kN\u00b7m torque capacity provides a comfortable safety margin over our peak drive torque.<\/p>\n

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

Fitted the TS7Z16\u00d745 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 119 MPa contact pressure distributes the load evenly around the shaft circumference.<\/p>\n

Used in agitator drive shaft connections on our chemical reactor vessels. The TS7Z16\u00d745 allows shaft removal for vessel maintenance without shaft modification \u2014 the locking assembly releases cleanly when the screws are backed off, unlike interference-fit hubs that require heating and pressing. The 16.8 kN axial load capacity covers our process torque requirements with margin.<\/p>\n
