Thread tighteners - Import export

Hybrid Technology – Smart Assembly Solutions The YOKOTA electric system wrenches with integrated torque transducer and angle sensor offer a large reduction of energy consumption, a high degree of accuracy and fantastic work efficiency. Torque transducer and angle sensor located directly at the front of the main shaft, giving the best accuracy of measurement. Faulty tightening detection with maximum accuracy due to the use of an integrated torque transducer and also an integrated angle sensor. During the tightening process, four different variables are measured and monitored: Torque - Angle - Time - Nº. of Impulses. Torque transducer measures directly and transmits the signals contactless. Detects cross threads, double hits, contamination, etc. Special feature to prevent cross threaded tightening: reversely rotating a bolt to a preset angle at the start of tightening. Combinations of buzzers and LED (Green / Red) for operator feedback on OK / NOK tightenings. [...]

Coupling stainless steel 1.4057. Screws stainless steel 1.4301. For applications that require a small construction volume and low surface pressure. The keyless locking coupling can be fully recessed in a hub connection. for shaft diameters 6 20 mm suitable for hubs with low wall thickness minimum axial offset possible selfcentring Assembly Lightly oil keyless locking coupling on the tapered faces and contact points of the shaft and hub. Do not use MoS2 or grease. Insert keyless locking coupling in the hub seat and slide onto shaft. Tighten screws crosswise in several increments to the defined tightening torque. Dismantling Remove all screws and screw into the extraction threads of the front flange. Tighten screws crosswise in several steps until the keyless locking coupling loosens. Tolerances Shaft Recommended tolerance h8. Surface quality Rz ≤ 16 µm. Hub Recommended tolerance H8. Surface quality Rz ≤ 16 µm.

Particularly compact selfcentring keyless locking coupling without axial offset. for shaft diameters from 8 to 85 mm for medium torques suitable for hubs with low wall thickness no axial offset selfcentring Assembly Lightly oil keyless locking coupling on the tapered faces and contact points of the shaft and hub.

Dismantling Remove all screws and screw into the extraction threads of the front flange. Tighten screws crosswise in several steps until the keyless locking coupling loosens. Tolerances Shaft Recommended tolerance h8. Surface quality Rz ≤ 16 µm. Hub Recommended tolerance H8. Surface quality Rz ≤ 16 µm.

The main purpose is to fix the parts in a plastic dowel of the appropriate diameter or: in wood, with pre-drilling, using metric fasteners (for example, fixing pipe clamps). The carving is rare, single-pass for wood on one side and metric on the other. It has a hexagon between the metric and the screw thread for tightening the screw stud.
