German MIKROSA coupling MIKROSA model MIKROSA price

MIKROSA 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.

MIKROSA coupling features

1) One-piece molded metal elastomer; 2) Zero backlash, capable of synchronous operation; 3) Elastic action compensates for radial, angular, and axial misalignment; 4) High torsional stiffness and excellent sensitivity; 5) Identical rotational characteristics in clockwise and counter-clockwise directions; 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.

MIKROSA 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 increase in torque and rigidity is 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.

MIKROSA coupling installation and fixation

1) Flexible coupling set screw fixation: Two set screws with a gap of 90º lock onto the shaft being 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 very common 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-shaped hole fixation: Typically, if the motor shaft is D-shaped, and set screws cannot be used for fixation, the coupling hole can be machined into a D-shaped hole corresponding to the motor shaft size, used in conjunction with set screw fixation, eliminating concerns about slippage. 5) Clamping hub fixation: Tightens the four set screws on the end face of the Lingsi coupling to compress the clamping hub for fixation. Suitable for connecting and fixing high-torque stepper motors and servo motors, such as clamping hub diaphragm couplings, clamping hub jaw couplings, clamping hub bellows couplings, and clamping hub flexible couplings.
