German Sauter Feinmechanik shaft, Sauter Feinmechanik model, Sauter Feinmechanik price

Sauter Feinmechanik shafts are used to support rotating parts, bearing only bending moments without transmitting torque. Some mandrels rotate, such as the axles of railway vehicles, while others do not rotate, such as the shafts supporting pulleys. Depending on whether the shaft rotates during operation, mandrels can be divided into rotating mandrels and fixed mandrels. Rotating mandrel: The shaft is subjected to a bending moment during operation and rotates; Fixed mandrel: The shaft is subjected to a bending moment during operation and remains stationary. According to the function of the shaft and the load it bears, it can be divided into mandrels, rotating shafts, and drive shafts: among them, the mandrel bears only bending moments without transmitting torque; the rotating shaft bears both bending moments and transmits torque; the drive shaft transmits only torque without bearing bending moments, or the bending moment is very small.

Sauter Feinmechanik shaft classification and structure

Commonly used mandrels include: 1) Small taper mandrel, which offers high positioning accuracy. However, loading and unloading workpieces with a small taper mandrel is inconvenient, and axial positioning is not possible, so it is only suitable for workpieces with small batch sizes, high precision requirements, and no axial positioning requirements; 2) Step mandrel tightened with a nut, suitable for clamping multiple workpieces and applications where workpiece precision requirements are not very high; 3) Expanding mandrel, which is convenient for loading and unloading workpieces and offers high precision, suitable for sleeve parts with large bore diameter tolerances. Mandrels include cylindrical, conical, elliptical ball head, inner hole, and internal thread types. In CNC turning, the structural shape formed by part turning is not complex, but the dimensional accuracy of the parts, especially the geometric accuracy, is required to be very high, with strict dimensional tolerances and surface roughness values for multiple diameters.

Sauter Feinmechanik shaft advantages

1) The mandrel maintains a large contact area with the hole, resulting in high positioning accuracy; 2) Uses the elastic deformation of the spring collet to center and clamp the workpiece, providing high positioning accuracy; 3) The fit clearance of the positioning surface affects positioning accuracy; 4) Uses Pascal's principle to elastically deform the thin-walled sleeve to center and clamp the workpiece, achieving high positioning accuracy with coaxiality reaching 5μm; 5) Can reduce clamping deformation of thin-walled sleeve workpieces, improving machining accuracy; 6) Has a positioning interference fit of 0.002mm, achieving extremely high positioning accuracy.

Sauter Feinmechanik shaft troubleshooting

When the vehicle is under heavy load, especially when driving over bumps, occasional knocking sounds may occur. Check whether the middle and rear axle balance shafts have shifted and are interfering with the drive shaft. If noise increases with vehicle speed during operation, accompanied by vibration, this is generally caused by imbalance of the drive shaft. This vibration is most noticeable in the cabin. The imbalance amount of the drive shaft dynamic balance should be less than 100 g. cm. Severe failure of drive shaft dynamic balance can lead to damage to related components. The most common issues are cracks in the clutch housing and fatigue damage to the intermediate rubber support. Solution: Chock the front wheels with wooden blocks, and use a jack to lift one side of the middle and rear drive axles; start the engine, engage high gear, and observe the oscillation of the drive shaft. During observation, note that if the oscillation significantly increases as the speed drops, it indicates that the drive shaft is bent or the flange is skewed. Drive shaft bending is usually bending of the shaft tube, mostly caused by vehicle overload. Coal transport vehicles frequently experience drive shaft bending and breakage due to overload and excessive trailing. For example, some vehicles towing trailers carrying more than 60 tons of coal suffer severe damage to the drive shaft due to overload and excessive trailing. Although the intermediate support of the drive shaft was reinforced and the strength of the flange yoke was increased, breakage failures still occurred. After replacing drive shaft components and straightening, a balance check should be performed, and the imbalance amount should meet standard requirements. The technical condition of the universal joint yoke and drive shaft hanger should also be carefully inspected. Improper installation, damage to the cross shaft and rollers causing looseness and vibration, can also cause the drive shaft to lose balance.
