546 Model (Toothed clutch)Torque is transmitted by engagement of teeth and large torque can be transmitted even though the clutch is small. There are “full position” with entire circumference engagement and “single position” with fixed position engagement (engaged at one position in one revolution). As a tooth tip configuration, full depth tooth usable in any rotation direction and saw tooth with higher relative velocity engagement are available.

Only one pressure screw allows easy and quick mounting and dismounting. A pressure medium sealed inside of the chamber is pressurized by fastening the pressure screw, and moves equally into the sleeve. By the pressurization of a pressure medium, the sleeve is pressured from inside to contract the shaft-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub through the sleeve. Since the ETP-TECHNO uses only one pressure screw to fasten, assembling time of equipment requiring a positioning can be substantially reduced. It is also useful for the place requiring a repetitive mounting and dismounting. Furthermore, a high-precision mounting and ultrahigh-precision positioning can be performed due to its excellent concentricity of 0.006 mm. A simple anti-rust specification with electroless nickel plating (ETP-T-C) is also available. ETP-T TypeOnly one pressure screw allows easy and quick mounting and dismounting.
