Design and Analysis for Weak Rigidity Combination Planetary Disc of Precision Ball Transmission
نویسندگان
چکیده
According to the structure and drive principle of the precision ball transmission, an innovative structure of weak rigidity combination planetary disc which set planetary motion and clearance adjustment function as a whole was proposed. The performance requirements of the key connection pair in weak rigidity combination planetary disc were analyzed. A structure connected by pins was designed. The analysis model which described the backlash in pin connection pair was established. The calculation formula of backlash was derived. The failure modes and strength of pin connection pair was analyzed. The Monte Carlo simulation and calculation of backlash was carried out through an example programming by the software MATLAB. The results show that the decrease of backlash can be accomplished by changing the structure parameters. The practicability of pin connection pair is verified by the backlash simulation and strength check. The results provide important theory basis for research on the real-time non gap precision ball transmission. Copyright © 2014 IFSA Publishing, S. L.

Objective(s): Hardystonite (HT) is Zn-modified silicate bioceramics with promising results for bone tissue regeneration. However, HT possesses no obvious apatite formation. Thus, in this study we incorporated Sr and Ti into HT to prepare Sr-Ti-hardystonite (Sr-Ti-HT) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. Ma...
