Germany ALLWEILER shaft ALLWEILER model ALLWEILER price

ALLWEILER shafts are used to support rotating components and withstand only bending moments without transmitting torque. Some spindle shafts 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, spindle shafts can be divided into rotating spindle shafts and fixed spindle shafts. Rotating spindle shaft: The shaft withstands bending moments during operation and rotates. Fixed spindle shaft: The shaft withstands bending moments during operation and remains stationary. Based on the function of the shaft and the loads it withstands, shafts can be classified into spindle shafts, rotating shafts, and transmission shafts: Spindle shaft: Withstands only bending moments without transmitting torque; Rotating shaft: Withstands both bending moments and transmits torque; Transmission shaft: Transmits only torque without withstanding bending moments, or the bending moment is very small.

ALLWEILER shaft classification and structure

Commonly used mandrels include: 1) Small taper mandrel, which has high positioning accuracy. However, it is not very convenient to load and unload workpieces with a small taper mandrel, and axial positioning is not possible, so it is only suitable for workpieces with small batches, high precision, and no axial positioning requirements; 2) Step mandrel tightened by nuts, suitable for clamping multiple workpieces and occasions where the workpiece precision requirement is not very high; 3) Expansion mandrel, due to the convenience of loading and unloading workpieces and high precision, it is suitable for sleeve parts with large bore tolerances. Mandrels include cylindrical, conical, elliptical ball head, inner hole, and internal thread. In data turning processing, the structural shape formed by part turning processing is not complex, but the dimensional accuracy of the parts, especially the geometric accuracy of the parts, is required to be very high, and its multiple diameter dimensions have strict dimensional tolerance and surface roughness value requirements.

ALLWEILER 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, resulting in high positioning accuracy; 3) The fit clearance of the positioning surface affects the 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 the clamping deformation of thin-walled sleeve workpieces, improving machining accuracy; 6) Has a positioning interference fit of 0.002mm, achieving extremely high positioning accuracy.

ALLWEILER shaft troubleshooting

When the car is under heavy load, especially when driving over bumps, occasional knocking sounds should prompt inspection of whether the middle and rear axle balance shafts have shifted and interfered 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 are cracks in the clutch housing and fatigue damage to the intermediate rubber support. Solution: Wedge the front wheels with blocks, lift one side of the middle and rear drive axles with a jack; start the engine, engage high gear, and observe the oscillation of the drive shaft. During observation, pay attention to when the speed decreases; if the oscillation significantly increases, 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 often experience failures such as bending and breaking of the drive shaft due to overload and excessive trailing. For example, some vehicles pulling more than 60 tons of coal with trailers 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 fork was strengthened, breakage and damage 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 fork and drive shaft hanger should also be carefully inspected. Improper installation causing looseness and vibration due to damage to the cross shaft and rollers can also cause the drive shaft to lose balance.
