How To Remove The German Calcium Carbonate Crushing Machine Bearing

Bearing disassembly is one of the important aspects of mechanical maintenance. Disassembly must follow the basic rules for German Calcium Carbonate Crushing Machine bearing disassembly, and different disassembly tools and disassembly methods are required for different German Calcium Carbonate Crushing Machine bearings. If the German Calcium Carbonate Crushing Machine bearing needs to be used again after disassembly, the force applied during disassembly must never be transmitted through the rolling elements. For split German Calcium Carbonate Crushing Machine bearings, the German Calcium Carbonate Crushing Machine bearing ring with the rolling element cage assembly can be removed separately from the other German Calcium Carbonate Crushing Machine bearing ring. When disassembling the non-separable German Calcium Carbonate Crushing Machine bearing, the German Calcium Carbonate Crushing Machine bearing ring with clearance fit should be removed first, and the German Calcium Carbonate Crushing Machine bearing with the interference fit should be disassembled. Different tools need to be used according to its type, size and fit. .

Disassemble The German Calcium Carbonate Crushing Machine Bearing Mounted On The Cylindrical Shaft Diameter

1, Cold Disassembly

When disassembling a smaller German Calcium Carbonate Crushing Machine bearing, gently tap the side of the German Calcium Carbonate Crushing Machine bearing ring with a suitable punch to remove it from the shaft. A better method is to use a mechanical puller (Figure 1). Pulling should act on the inner ring or adjacent parts. The disassembly process can be simplified if the shoulders and the shoulders of the German Calcium Carbonate Crushing Machine housing are provided with recesses that accommodate the pull of the puller. In addition, some threaded holes are machined in the position of the shoulder to facilitate the bolting of the German Calcium Carbonate Crushing Machine bearing (Fig. 2).

Large and medium-sized German Calcium Carbonate Crushing Machine bearings typically require more force than mechanical tools can provide. Therefore, it is recommended to use hydraulic power tools or oil injection methods, or both. This means that oil holes and oil grooves need to be designed on the shaft (Fig. 3).

2, Thermal Disassembly

When disassembling the needle German Calcium Carbonate Crushing Machine bearings or the inner rings of the NU, NJ, and NUP cylindrical roller German Calcium Carbonate Crushing Machine bearings, it is suitable to use the thermal disassembly method. Two commonly used heating tools: heating rings and adjustable induction heaters.

The heating ring is typically used to install and remove the inner ring of a small to medium size German Calcium Carbonate Crushing Machine bearing of the same size. The heating ring is made of a light alloy. The heating ring has a radial slot and is equipped with an electrically insulated handle (Figure 4).

Debugable induction heaters are recommended if the inner rings of different diameters are frequently removed. These heaters (Figure 5) can heat the inner ring quickly without heating the shaft. When disassembling the inner ring of a large cylindrical roller German Calcium Carbonate Crushing Machine bearing, some special fixed induction heaters can be used.

Disassemble The German Calcium Carbonate Crushing Machine Bearing Mounted On The Conical Shaft Diameter

The small German Calcium Carbonate Crushing Machine bearing can be removed by pulling the inner ring with a mechanical or hydraulic assist puller. Some pullers are equipped with a spring-operated arm. Using this self-centering puller simplifies the procedure and avoids damage to the journal. If the puller jaws cannot be used on the inner ring, the German Calcium Carbonate Crushing Machine bearings should be removed via the outer ring or with a puller in combination with the pull tab (Figure 6).

When using the oil filling method, the disassembly of the medium and large German Calcium Carbonate Crushing Machine bearings is safer and simpler. This method injects hydraulic oil between two conical mating faces through an oil hole and an oil sump under high pressure. The friction between the two surfaces is greatly reduced and produces an axial force that separates the German Calcium Carbonate Crushing Machine bearing from the shaft diameter.

Remove The German Calcium Carbonate Crushing Machine Bearing On The Adapter Sleeve

For small German Calcium Carbonate Crushing Machine bearings mounted on a tight-fitting straight shaft, a hammer can be used to strike a small steel block that acts evenly on the end face of the inner ring of the German Calcium Carbonate Crushing Machine (Figure 7). Prior to this, the adapter sleeve lock nut needs to be loosened several times.


For small German Calcium Carbonate Crushing Machine bearings mounted on a tightly fitted stepped shaft, the hammer can be removed by tapping the small end face of the adapter sleeve lock nut with a special sleeve (Fig. 8). Prior to this, the adapter sleeve lock nut needs to be loosened several times.

For German Calcium Carbonate Crushing Machine bearings mounted on tightly fitted stepped shafts, the use of hydraulic nuts makes it easier to disassemble the German Calcium Carbonate Crushing Machine bearings. For this purpose, a suitable stop (Fig. 9) must be installed in close proximity to the hydraulic nut piston. The oil filling method is an easier method, but an adapter sleeve with oil holes and oil grooves must be used.

Disassemble The German Calcium Carbonate Crushing Machine Bearing On The Withdrawal Sleeve

When removing the German Calcium Carbonate Crushing Machine bearing on the withdrawal sleeve, the locking device must be removed. (For example, lock nut, end plate, etc.) For small and medium-sized German Calcium Carbonate Crushing Machine bearings, use a lock nut, hook wrench or impact wrench for disassembly (Figure 10).

For medium and large German Calcium Carbonate Crushing Machine bearings mounted on the withdrawal sleeve, it can be easily removed with a hydraulic nut. It is recommended to install a stop behind the hydraulic nut at the shaft end. The stop device prevents the withdrawal sleeve and the hydraulic nut from flying out of the shaft when the withdrawal sleeve is suddenly separated from the engaged position.
