  • Friction torque testing machine designed by ball screw manufacturer

    Each screw has a non abrasive part at the end. The section length is 200 mm. The friction torque can be dynamically monitored by testing machine. When the fluctuation of friction torque exceeds the range of test parameters, the nut is considered to be worn and will be replaced. When the grinding experiment is completed, clean the test screw and measure the change in travel, and then cut the screw to obtain sample fragments. The length of the sample is 8

  • Ball screw manufacturers provide precision machining and transportation

    Ball screw drives usually provide mechanical efficiency greater than 90, so their cost is often offset by low power requirements. The ball screw has increased load capacity, long life and predictable predictability on the screw. Repeatability and accuracy are measures of how close the motion system is to the command position, and are defined as the large error between the expected position and the actual position. Repeatability definition system

  • Ball screw manufacturers are widely used in CNC machine tools

    It's a raceway that contains a rolling bearing, and the ball moves up and down the screw. Ball bearings reduce friction. Recently, I have published some blog articles about ball screw. Some of the information is basic, but it also includes preloading and friction. In addition, they are likely to expand this topic in future articles. Watch the video below if you like. First of all, the cost of guide screw is lower than that of guide screw

  • Preload of two nuts used by ball screw manufacturer

    The ball screw produces low friction. They achieve high conversion efficiency while keeping the running torque at one third of the sliding screw. A large thrust load can be obtained at low torque. Figures 2.1 and 2.2 show the transfer efficiency of the ball screw. Ball screws convert rotary motion into linear motion in normal use, but can also be used to convert linear motion to rotary motion(

    Note that the ball is re looped through the end cap installed in each end. The spherical re circulation tunnel is constructed in the inner wall of the nut. Suitable for high speed operation. The screw is inserted into the outer guide tube of each screw rod to make it pass through the guide rod. Suitable for compact design. The return line is mounted outside the nut. The simplicity of assembly makes it suitable for mass production, but the overall size is relative to other methods

  • Ball screw manufacturer to check both ends of nut assembly

    A recent application requires the brake to be mounted directly on the drive for all reasons. The initial installation uses a brake motor with a brake at the rear of the dual shaft motor. However, these components take up too much space and their braking torque does not stop and hold the load. The ball screw brake, which is directly connected to the end of the ball screw, can save space and when applied directly to the ball screw

  • Ball screw manufacturer designed for service

    Compare these worn spots to areas where the nut does not move frequently. Keep the lubrication system working properly. Clean the ball nut with grease. High lubrication system pressure will ensure good flushing and lubrication. Make sure you can see the oil. Check whether the oil is clear or contaminated. If the lubrication system does not work properly, remove the ball screw as soon as possible. This is to check the lubrication system

  • Ball screw manufacturer to check torque alignment

    Attach the housing to the saddle by tightening (slightly) four bolts. Turn and screw the table away. Let's find the "middle" of the shell and tighten it a little bit more. Repeat this process until the torque turns the y-axis screw as if it were a screw stroke. Tighten the screws to secure the housing to the saddle. You may want to drill some pinholes to secure the housing to the saddle (optional). X-axis retaining screw

  • The ball screw manufacturer checks the whole lubrication system

    But for most applications of series mills, they are not. Angular contact bearing sets will be entered requiring a set of gaskets. The inner ring gasket should be placed in front of the bearing. The outer race gasket should be placed before the bearing bore to install the bearing. When tightening the bearing, do not tighten the retaining ring too tightly. The bearing retaining ring is made of aluminum and the screw head can be broken. Bearing before

    This forces the grease fed into the manifold to install the support unit on the ball screw shaft through the clearance. Install the fixed end support unit to the ball screw shaft. Do not remove the support unit. When inserting the screw shaft into the support unit. Please don't scrape off the oil seal. . ball screw shaft into the fixed side, please use the fixed part to tighten the lock nut.

  • Ball screw manufacturers have free space

    For these ball nuts, grease can be pumped directly into the nuts. Please refer to the catalog to confirm which ball nuts have threaded grease holes. It is recommended that these nuts be used in conjunction with a to contain lubricant in the nut contents. The ball screw may require more frequent operation depending on the ambient conditions. If the lubricant appears to have been

  • Ball screw manufacturers should pay attention to the following points

    Running in should be performed initially, after start-up and each subsequent relubrication. Lubrication life when relubricated at an appropriate frequency, the ball screw should reach the rated fatigue life. If there is no re lubrication, it will be affected by the operating speed, operating temperature and environmental pollution. Good relubrication intervals are determined by experience. Changes in grease consistency, grease color, operating torque and lubricant
