Pushing of large spiral angle oil groove
In the mechanical parts, the surface of the inner surface of the sliding bearing needs to be opened with various forms of oil grooves such as straight lines or spirals, so that the lubricating oil is fully distributed to the bearing working surface to reduce the friction between the bearing and the journal, improve the mechanical efficiency and prolong the use. Lifetime, in the hydraulic components, the oil grooves in some bushings (equivalent to sliding bearings) have both lubrication and balance of hydraulic pressure. The processing of linear oil grooves is relatively easy, and the spiral is especially large.
