High elastic coupling is a kind of torsional high elastic coupling, which is suitable for medium and small horsepower gear box, but also for other power transmission devices with diesel engine as the main power, the main components have inner gear ring and elastic components with teeth. The series of high-elastic coupling is made of heat-resistant rubber as shock absorbing material, which can effectively reduce and absorb shock, improve the working condition of the device, improve the service coefficient and transmission capacity, extend the maintenance cycle and service life of the equipment, and improve the sailing condition of the ship. The coupling adopts axial insertion type, so it can compensate large axial displacement and certain radial displacement and angular displacement, and it is easy to install. The coupling is an indispensable supporting product for the upgrading of medium and small horsepower power plant. The allowable working temperature of the elastic element of the coupling is 60℃. In order to extend its service life, it is recommended not to use an outer cover as far as possible. When the outer cover must be used, enough ventilation should be given for the side of the coupling to use parallel or spiral grooving system to adapt to various deviations and transfer torque. Elastic couplings usually have good performance and price advantages, and in many practical applications of stepping and servo systems, elastic couplings are the products of choice. The integrated design enables the elastic coupling to transmit torque with zero clearance and no maintenance.

Features：

 (1) metal elastomer formed in one body; (2) Zero rotation clearance, synchronous operation; (3) Elastic action compensates radial, angular and axial deviations; (4) High torque rigidity and sensitivity; (5) Full phase of clockwise and counter-clockwise rotation (6) maintenance-free, oil resistance and corrosion resistance;

Apply：

Most of the elastic couplings are made of aluminum alloy, and some manufacturers also provide elastic couplings made of stainless steel. In addition to corrosion resistance, stainless steel elastic coupling also increases the torque bearing capacity and rigidity, and can even reach twice that of similar products made of aluminum alloy. However, this increase in torque and rigidity is offset to some extent by the increase in mass and inertia. Sometimes the negative effects outweigh the advantages, forcing the user to look for other forms of coupling.
