    How to find the alignment error of the coupling and the solution to the error

      In chemical plants, 50% to 70% of the damage to the transmission equipment is caused by the out-of-alignment of the coupling. The direct loss is the cost of replacing spare parts, and the indirect loss is the unplanned shutdown which causes greater downtime profit loss. , How to detect the alignment error of the coupling early and take timely measures..

    What are the precautions for hot mounting couplings?

      The preparatory work for the hot-installation of the coupling firstly wash and wipe the matching part of the journal and the coupling with gasoline or kerosene.If there is roughness and damage, use whetstone and fine emery cloth to eliminate it, or use other methods to deal with it.Secondly, use a micrometer and a micrometer to carefully measure the inner diameter of the journal and coupling.

    Basic structure of permanent magnet coupling

      The permanent magnet coupling is a coupling that uses the magnetism of permanent magnets for transmission. This type of coupling has no direct contact between the driving and driven half couplings, so there is no friction, no noise, and Absorbs a certain degree of shaft displacement and angular displacement error, and can play a skid and protection role when overloaded. It is suitable for light high rotation..

    Z-type shaft hole, J-type shaft hole, Y-type shaft hole on the coupling

      There are three types of shaft holes for couplings: Y-type, J-type, and Z-type. Y-type shaft hole is a long cylindrical shaft hole, J-type shaft hole is divided into J type and J1 type, J type is a short cylindrical shaft hole with counterbore, and J1 type is a short cylindrical shaft hole without counterbore. Z type shaft hole is divided into Z type and Z1 type, Z type is a short circle with counterbore..

    How to analyze the cause of damage to the elastic sleeve pin coupling

      The main elastic drum gear coupling of the elastic coupling is the rubber component that changes the load. The rubber component can be planned into single row or multiple rows. Each rubber component has a variety of standard stiffnesses to choose from, which can be twisted satisfactorily on a large scale. Vibration calculation confirmed the stiffness requirements, drum-shaped gear coupling.Used in ship power system..

    How to choose the servo coupling correctly

      Choosing a coupling for a servo system is a complicated process. This process needs to consider requirements such as torque, relative displacement of the shaft, hardness, speed, and size.In order to ensure the normal operation of the coupling, these requirements must be very matched.Before selecting couplings, perform the performance and application details of these couplings..
