What causes rust on slip shafts? The half shaft is badly rusty, what s the matter

The quality of anti-rust lubricating oil, cleaning kerosene and other products used in the production of THK guide rails is not up to standard, and some are not even maintained, no matter how good the guide rails are, they will inevitably rust, you can choose Shanghai Manlu. 2. The operating environment conditions of the guide rail are poor, the content of harmful substances in the air is high, and the turnover site is too small, which makes it difficult to carry out effective anti-rust treatment. At the same time, it is affected by the air environment, temperature, humidity and pH, etc.

Ball screws consist of screws, nuts, and balls. Its function is to convert the rotary motion into linear motion, which is a further extension and development of the ball screw, and the important significance of this development is to change the bearing from sliding action to rolling action. Due to their low frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments.

Ball screws are the most commonly used transmission elements in machine tools and precision machinery, and their main function is to convert rotary motion into linear motion, or torque into axial reciprocal force, while having the characteristics of high precision, reversibility and high efficiency. Ball screw common fault diagnosis and elimination methods: fault phenomenon:

The roughness value of the workpiece is high.

Cause of failure: The lubricating oil of the guide rail is not enough, which causes the slide to crawl.

Elimination method: add lubricating oil to eliminate lubrication fault phenomenon: the ball screw has local brushing or grinding.

Elimination method: replace or repair the screw rod fault phenomenon: the screw bearing is damaged, and the movement is not stable.

Troubleshooting method: Replace the damaged bearing fault phenomenon: the servo motor is not adjusted well, and the gain is too large.

Elimination method: adjust the fault phenomenon of the servo motor control system: the reverse error is large, and the machining accuracy is unstable.

The rust of the slip shaft is mainly because the electroplating of the slip shaft is not done well, and after a period of use, it will bump and bump, and the plating on the surface will be removed, and the rust will appear in the humid environment. Therefore, we should try to avoid the phenomenon of bumps and bumps in daily life, and when the slip shaft is not used, the slip shaft should be oiled and protected, and at the same time, it should be kept away from the humid environment to prevent the slip shaft from rusting. -Tianji transmission.

It depends on the degree of corrosion.

We know that the half bearing is subject to the torsional force of rotation, not the shear force, so the premise to ensure the working capacity is that the half shaft must have sufficient radius dimensions and the strength of the spline connecting the half shaft gear of the differential.

Under the same material and radius size, the size and strength of the spline are definitely inferior to the half shaft, so the general appearance of rust has little impact on the half shaft. But if the rust is so bad that it pits, or even rusts off a third of the diameter, this half shaft will definitely not be usable.

The half shaft of a car is just a small part of the car, and as long as the rust does not penetrate into the material, the impact on the overall performance of the car is negligible. Rust of body parts may be due to the lack of anti-rust measures before leaving the factory, of course, it is also directly related to the environment and climate, and humid or saline-alkaline areas are easy to cause rust of chassis suspension and other components. The body of the new car has been rust-proof before leaving the factory, and if there is still rust, then it may be that the anti-rust treatment is not in place.

It is recommended to go to the 4S store where you purchased the car for an inspection, and if necessary, apply for a claim replacement.

Is it a car half-shaft? Most car half shafts will not rust, if rust is recommended to replace it with a new one.
