The star-shaped elastic coupling structure makes the center of gravity of the left and right sides of the unit close to the support bearings of the units on both sides to the greatest extent, and the additional bending moment on the rotor shaft head is small, which is conducive to high-speed and stable operation. When the load of the equipment increases or decreases suddenly, the friction block and the friction wheel produce intermittent relative motion, thereby deforming the impact load, and repeatedly impacting the joint surface of the shaft sleeve at the output end of the star-shaped elastic coupling and the input shaft of the reducer.
Star couplings.
For example, the hammer strikes the joint surface countless times, thereby damaging the joint surface and key pin. It cannot be bent and squeezed, and it can be hung vertically if conditions exist to prevent deformation. Under the condition of severe overload or stalled rotor, the torque at the load end is greater than the friction torque, and the centripetal force of the centrifugal friction block decreases, resulting in the reduction of the force on the slider, and the star elastic coupling plays a role in overload protection.
In order to effectively improve the operating condition of the equipment, it is necessary to change the connection device of the electromechanical equipment. Attention should be paid to the protection of the star elastic coupling during transportation, installation and use, to avoid bumps or scratches, and the star elastic coupling is forbidden to be placed vertically. The short-term overload capacity is the rated torque, and the operation is stable, taking into account the requirements of economy and practicability. When the axial serial momentum of the coupling is valued, the axial clearance of the fixed support seat must be adjusted.
Flexible couplings.
Absorb the deformation caused by misalignment, there is no relative movement between parts, no friction and wear, so no lubrication is required, in line with the development direction of oil-free process equipment. The bearing capacity of the star elastic coupling can improve this, and it can be designed according to the large load, constrained by the spring strength and installation space, and the coupling stiffness is small, so as to meet the requirements of the bearing capacity, and the stiffness can also be small, so as to have good cushioning and damping performance.
