Universal couplingErrors may be generated in the application and the entire process of the application and the previous and the application, and the situation of the error is not clear to the human eye.How to find the correct method for universal joints?
First take about 4 points, fix it with a block meter, and then rotate the meter fixed on the shaft. Each load is read at each point of the meter: first adjust the upper and lower sum, read the right and left basis, so that the motor or reducer has obvious Timber and oblique situation.Check the inner diameter percentage table, adjust the upper and lower parts of the reducer according to the upper and lower reading values, so that the upper and lower standards are within the allowable deviation range.After adjusting the top and bottom specifications, based on the left and right read values, the adjustment pad is clearly indicated in order to ensure that the left and right deviations are within the range.After the above process, you can understand how to find the universal coupling.
Since the center of gravity of the universal joint is different, or the rotation center line of the universal joint does not overlap between the inertial force main bearing, it is called an electric motor under the conditions of unbalanced inertial force, centripetal force and dynamic rigidity during operation. The unbalanced condition of the rotor. The unbalanced condition corresponds to the inevitable shaft vibration and the normal operation of the equipment. In order to minimize the damage caused by this situation, Universal Coupling improves this situation by balancing the dynamic balance of the rotor.After the product is manufactured or installed on the equipment, the specific balance or correction scheme of the shaft is specified, and the balance level is specified by appropriately increasing or reducing the quality.The whole process of adhering to this process is called balance efficiency, that is, balance.
Universal coupling equalization is a way to check the quality of the motor rotor.If necessary, adjust its quality spread to limit the vibration of the rolling bearing or limit the force of the rolling bearing.
Types of unbalanced universal couplings:
Universal coupling 1, single-sided unbalanced state
If the center of gravity is not on the arc, there will be single-sided and double-sided unbalance.At this time, regardless of the relative position between the mass and the shaft, it is not easy to be in static equilibrium.Place the unbalanced block on the two parallel horizontal bars or the motor shaft of the slide rail, and observe the single-sided and double-sided internal position and viewing angle effect.Focus on the target and immediately turn to the position below the center line. It is the symmetrical point between the hanging object side and the center of rotation, plus the balance weight at the half-warp part of the motor rotor for static data. In the balancing machine, the order can be completed without the motor rotor. Balance within two sides.
2. Unbalanced state on both sides
When there is an unbalanced phase difference between the two plan views, the phase difference is not necessarily 180.The inertial force in the arc and the deviation of the initial axis from the initial axis cause deflection.In all normal situations, two axes that are inclined to each other are present.When the unbalanced torsion bearing coupling is not restricted, it rotates around the spindle bearing with the inertial force, and the longitudinal axis of the spindle geometry is the same.Torques with the same size and opposite directions can be referred to as coupling unbalanced torque.
Couplings are often used in various mechanical equipment, whether it is the connection of the robot arm or the area of the transmission gear of the transmission system, the universal coupling must be present.Since its application is very common, its maintenance is also very important.Because the location it has is all a more critical part of the mechanical equipment, once a problem arises, the equipment will also encounter the crisis of downtime.
So how do people generally treatUniversal couplingWhat about maintenance?Since the coupling is generally working under extremely high working pressure, the damage to itself is very serious. At this time, people must often add some lubricating fluid to the coupling to reduce its impact. Wear rate under working pressure.And if the office environment is more extreme, then lubricating fluid must be added to show good lubrication.
