India Sand Core Crushing Machine Bearing

The main function of the bearing is to support the mechanical rotating body, to ensure the working position and accuracy of the shaft and shaft transmission parts, reduce friction and wear, and bear the load.

India Sand Core Crushing Machine Bearing Disassembly Method



Take the rolling India Sand Core Crushing Machine bearing as an example to see the following five disassembly methods and how to choose.

  • 1. Dumping method: The India Sand Core Crushing Machine bearing is removed by the impact energy generated by hammering the copper rod or soft iron.
  • 2. Pulling method: The drawing method should be used for the India Sand Core Crushing Machine bearing parts which are not allowed to be knocked or can not be removed by unloading. It is disassembled with a special puller. As shown in Figure 1, Figure 2:
  • 3, top pressure method: the use of spiral C-type chuck, mechanical press, hydraulic press or jack and other tools and equipment for disassembly. Suitable for India Sand Core Crushing Machine bearings with interference fit, as shown in Figure 3.
  • 4, temperature difference method: temperature difference method is to use the material thermal expansion and contraction performance, heating the containment parts, so that the fittings lose the interference under the temperature difference conditions, to achieve disassembly, generally with the special electric heater matched with the India Sand Core Crushing Machine bearing.
  • 5. Destruction method: If the India Sand Core Crushing Machine bearing and the shaft or the casing or the sleeve are bitten to each other, or the secondary part is destroyed for saving the main part, the cutting and the like may be used for the destructive disassembly.

India Sand Core Crushing Machine Bearing Common Assembly Method

  • 1. Knocking method: When the interference is small, you can use the hammer to knock into the India Sand Core Crushing Machine bearing; the method is to place the copper rod or soft iron and sleeve on the inner or outer ring of the India Sand Core Crushing Machine bearing. The hammer hammer strikes the copper rod symmetrically to load the India Sand Core Crushing Machine bearing evenly.
  • 2. Top pressure method: When the interference is large, the press can be pressed into the India Sand Core Crushing Machine bearing, and the sleeve must be placed when pressing. See Figure 4, Figure 5, and Figure 6 below.
  • 3. Temperature difference method: When the interference is large, the temperature difference method can be used for assembly, and the temperature difference method of the India Sand Core Crushing Machine bearing is assembled. The method of hot assembly is often used during maintenance. The heating method is electric heater and oil bath heating. Among them, electric heaters are widely used on site.
