In the figure, the function of the piece only serves to enable the piece to be mounted on the piece so that the three become a whole, and theoretically it is not force. For the joint size sail bearing, the deviation of the inner ring of the thrust bearing member is also the deviation of the outer ring of the radial bearing of the fitting. The radial coefficient is the axial coefficient for the bearing life index, the roller bearing.
For this design scheme, from the results of computer calculation, in addition to the four lower shaft inner bearing in the dangerous working condition, the outer bearing of the five-axis outer side should also be given full attention, and the spare parts should be properly prepared. The other sets of bearings are working under relatively safe working conditions and long-life working conditions, so it is not necessary to prepare spare parts, so as to avoid increasing the inventory and occupying more funds. It proves that it is a superior speed reducer in cylindrical worm drive. The worm reducer absorbs the rich experience and achievements accumulated in domestic scientific research and production, adopts the advantages of the German company's products, and improves the structure of the toothed material. The combination of geometric parameters is more flexible.
Therefore, in the development process, we pay attention to highlighting the principle of the tooth shape, the meshing characteristics, and working hard on the worm wheel to make the product meet the standard. The angles are different, so the bearing capacity and efficiency of each part are different. This is the main feature of the worm drive. Secondly, the way to improve the bearing capacity of the worm reducer From the meshing characteristics, the main factor affecting the bearing capacity of the worm reducer is the friction coefficient and the contact stress between the common knives.
