Germany CENTA Antriebe Kirschey coupling CENTA Antriebe Kirschey model CENTA Antriebe Kirschey price

CENTA Antriebe Kirschey coupling is a widely used coupling, also known as a jaw coupling, consisting of two metal jaw hubs and an elastomer. The two metal jaw hubs are generally made of 45 steel, but aluminum alloy is also used when load sensitivity is required.

CENTA Antriebe Kirschey coupling features

1) One-piece metal elastomer; 2) Zero backlash, synchronous operation; 3) Elastic action compensates for radial, angular, and axial misalignment; 4) High torque rigidity and excellent sensitivity; 5) Identical clockwise and counter-clockwise rotation characteristics; 6) Maintenance-free, oil-resistant, and corrosion-resistant; 7) Available in aluminum alloy and stainless steel materials; 8) Main fixation methods are set screw and clamping.

CENTA Antriebe Kirschey coupling application range

Flexible couplings are made of aluminum alloy, and some manufacturers also offer flexible couplings made of stainless steel. In addition to corrosion resistance, stainless steel flexible couplings also increase torque capacity and rigidity, even reaching twice that of aluminum alloy products of the same type. However, this increased torque and rigidity are offset to some extent by the increased mass and inertia. Sometimes the negative effects outweigh the advantages, forcing users to look for other types of couplings.

CENTA Antriebe Kirschey coupling installation and fixation

1) Flexible coupling set screw fixation: Two set screws with a gap of 90º tighten against the shaft to be fixed. This is a traditional fixation method; since the tip of the screw contacts the shaft center, it may cause damage to the shaft center or make disassembly difficult. 2) Lingsi flexible coupling clamping screw fixation: Uses the tightening force of hexagon socket head cap screws to contract the slit, tightly clamping the shaft center. This method is convenient for fixation and disassembly, does not damage the shaft center, and is a commonly used fixation method. 3) Flexible coupling keyway fixation: Suitable for high-torque transmission. To prevent axial slippage, it is usually used in combination with set screw fixation and clamping screw fixation. 4) Flexible coupling D-hole fixation: Typically, if the motor shaft is D-shaped, and set screws cannot secure it, the coupling hole can be machined into a D-shaped hole corresponding to the motor shaft size, used with set screw fixation to prevent slippage. 5) Clamping hub fixation: Tightens the four set screws on the end face of the Lingsi coupling to compress the clamping hub for secure fixation. Suitable for connecting and fixing high-torque stepper motors and servo motors, such as clamping hub disc couplings, clamping hub jaw couplings, clamping hub bellows couplings, and clamping hub flexible couplings.
