Coupler Pressing Machine The Main Quality Requirements Are High

The assembly of the Coupler Pressing Machine on the shaft is one of the keys to the Coupler Pressing Machine installation. Coupler Pressing Machine and shaft with the most of the interference fit, the connection is divided into key and keyless connection, Coupler Pressing Machine shaft hole is divided into cylindrical shaft hole and cone shaft hole two forms. Assembly methods are static press method, power press method, temperature assembly method and hydraulic assembly method.

Static press method: This method is based on the size of the required press force when assembling, the use of clamp, jack, manual or mobile presses, static pressure method is generally used for conical shaft hole. As the static press method by the pressure of mechanical restrictions, in the larger interference, the application of a lot of force more difficult. At the same time, in the process of pressing will be cut between the Coupler Pressing Machine and the axis of the uneven surface of the uneven crest, so that the mating surface is damaged. Therefore, this method is generally not much application.

Power press method: This method refers to the use of impact tools or machinery to complete the assembly process, generally used for Coupler Pressing Machine between the shaft and the shaft is a combination of transition or interference is not the occasion. The assembly site is usually a method of hitting a hand hammer by placing a piece of wood or other soft material on the end face of the hub as a cushion, depending on the impact of the hammer, the Coupler Pressing Machine. This method of cast iron, quenched steel, cast alloys and other brittle materials made of the Coupler Pressing Machine of the risk of local damage, should not be used. This method will also damage the surface with the assembly, it is often used for low-speed and small Coupler Pressing Machine assembly.

Check after assembly: After the Coupler Pressing Machine is assembled on the shaft, the vertical and coaxial degrees of the Coupler Pressing Machine and the shaft should be carefully checked. Usually in the Coupler Pressing Machine of the end and the outer circle set up two dial indicator, turning the shaft when the shaft, observe the Coupler Pressing Machine of the whole beating (including the end of beating and radial run) values, determine the Coupler Pressing Machine and the shaft Of the degree of verticality and coaxiality of the situation. Different speed, different types of Coupler Pressing Machine on the requirements of the whole beating different, the Coupler Pressing Machine in the shaft after assembly, you must make the Coupler Pressing Machine of the total beating deviation in the design requirements of the tolerance range, which is the Coupler Pressing Machine One of the main quality requirements of the assembly. There are many reasons why the full jitter of the Coupler Pressing Machine does not meet the requirements, first of all may be due to processing errors. For the field assembly, due to improper assembly of the key caused by the Coupler Pressing Machine shaft and shaft different axis. The correct installation of the key should be the key side of the key and the keyway wall close fit, usually in the assembly with color inspection, with a bad time can be used to repair the file or blade to meet the requirements. Key at the top of the general gap, about 0.1-0.2mm or so.

High-speed rotating machinery for the Coupler Pressing Machine and shaft coaxial degree of high demand, with a single bond can not get a high degree of coaxial, with double bond or spline connection can make the coaxial degree of both improved.
