By keeping various demands and requirements of the customers in mind, we are presenting a client specific array of Locking Element. Our products consist of an internal and external tapered ring that is manufactured by using high grade material. Also, this Locking Element is accurate in dimension and perfect in finishing.

 

Characteristics:

  • Customized application: By varying the number of Locking Elements, size and quantity of clamping screws, the connection can be adapted to fit most applications concerning surface pressures, materials, hub/shaft dimensions and available mounting space.
  • Transmission of high loads: To increase the transmissible torque and axial forces up to 4 Locking Elements can be used in series.
  • Maximum reliability: No matter whether the connection is subjected to static, pulsating, dynamic or intermittent loads.
  • Simple manufacture: Shaft and hub are designed without keyway. Apart from this, relatively large tolerances are admissible.
  • Easy adjustability: Locking Elements work without positive connection. So they can be adjusted at any place to any position by following the simple installation and removal instructions.
  • Backlash-free: The Locking Element connection is a mechanical shrink fit and will not wear or loosen in service provided that the maximum transmissible values for the connection are not exceeded.
  • High fatigue strength under alternating tensional stresses: As neither the shaft nor the hub has grooves the notch effect is minimized and a higher polar section modulus is given, enabling the use of smaller diameters.
  • Simple installation: In comparison to cross-press fits temperature treatments and fitting are eliminated. Screws have to be tightened with standard tools.
  • Easy removal: Locking Elements are self releasing no additional measures or auxiliary equipment is required.
  • Wear and maintenance-free: Unlimited lifetime if designed and used correctly.

 

Mounting of Locking Element:

 

  • The values for T and Fax, apply to Locking Elements installed in oiled condition.

 

Surface finishes:

  • For shafts and hub bores Ra ≤ 1 μm

 

Required screw tension force:

  • For Locking Elements solid: FA = FA´ + F0
  • For Locking Elements slit: FA = FA´
