There are many types of couplings, which can be divided into two categories according to their compensation capacity and working principle: I. Rigid coupling: Features: Simple structure, low cost, large torque transmission, no elastic elements. Requires strict and accurate alignment of the two connected shafts. Very sensitive to installation errors and shaft deformation, and cannot […]
Definition: A coupling is a mechanical device used to connect a drive shaft (active shaft) and a driven shaft so that the two shafts rotate together to transmit motion and torque (rotational power). Core functions: Transmitting torque: The most fundamental function is to transmit power from the active shaft to the driven shaft. Compensating for
Replace the entire nut assembly: This is the most reliable, time-saving and lowest overall cost solution. The new nut guarantees the original factory accuracy, preload and life. Professional repair service: Contact the ball screw manufacturer or authorized repair center. They have: .Original spare parts (balls, seals, returners). .Special tools and tooling. .Dust-free workshop. .Rich experience
Ultimate advice: Alternative solutions are far better than self-replacement Read More »
I. Preparation Safety protection: Cut off the power supply of the equipment and lock it. Wear dust-free gloves and finger cots. Environmental preparation: Perform in a clean bench or clean room. Thoroughly clean the work area. 2.Tools and consumables: Original special nut removal tools (such as removal pins, clamp wrenches, etc.). A complete set of

The internal structure of the ball screw nut is precise and complex, and the ball bears high loads and rolls precisely in its circulation channel (raceway, returner, return tube).Damage to a single ball (fragmentation, indentation, severe wear) will accelerate the failure of the entire system. Replacing the ball seems simple, but it is actually a

Successful repair is not the end, good maintenance is the key to ensure the long-term stable operation of the ball screw: I. Regular lubrication: Lubricate strictly according to the time interval and grease brand specified by the manufacturer. This is the most important maintenance! Use a dedicated grease nozzle or automatic lubrication system. The amount
1. Preparation for disassembly: Clean the outside of the screw and the surrounding area thoroughly to prevent contaminants from entering during disassembly. Record the original state: mark the position and direction of the nut and support bearing; measure and record the original preload (if possible) and axial clearance (usually measured with a dial indicator). Disconnect

As a crucial precision transmission element in modern mechanical equipment, ball screws are widely used in high-precision fields such as CNC machine tools, automation equipment, semiconductor manufacturing, and medical equipment. Mastering the correct maintenance knowledge can not only restore equipment performance in time, but also effectively extend the life of the screw and reduce overall
In the field of mechanical design and manufacturing, mechanism installation components refer to basic components used to connect and fix various mechanical parts to ensure the stable, safe and efficient operation of mechanical systems. These components play a key role in the assembly, maintenance and maintenance of mechanical equipment. I. Main types Bolts and nuts

The basic principle of ball screw precision classification is the deviation between the actual moving distance and the ideal moving distance in the transmission. The smaller the deviation, the higher the precision. There are three cases: The first is the running accuracy of one rotation; the second is the running accuracy of the entire ball
