This paper presents results of a study investigating worm gears consisting of polymer worm wheels and steel involute and Archimedes worms. The author uses his own calculation method to predict polymer wheel wear, gear life and maximum contact pressure in mesh. The effect of tooth correction and wear on gear life and contact pressure is considered. Cases of double and triple tooth engagement are analysed...
Total hip arthroplasty is a complex procedure. The achievements of implantology enabled the development of a faithful representation of hip joint physiology as well as the production of materials that can successfully replace damaged natural tissues. The challenge is to correctly select the geometry of the endoprosthesis adequate to the load of the joint. Materials used for endoprosthesis are a metal...
On the basis of the elaborated calculation method, the optimal width in involute helical gears was determined ensuring a constant length of the line of contact between the meshing gears that is based on the novel method for determining the wear and durability of the gears which was employed to measure the maximum contact pressures, linear wear of teeth and durability of the gear with angular correction...
Based on the elaborated calculation method he authors method for determining the wear and durability of gears was employed to measure the maximum contact pressures, linear wear of teeth and durability of the gear with height correction of the profile. The optimal condition width in involute helical gears is indicated ensuring constant length of the line of contact between the meshing gears. As a result,...
