Abstract

The invention discloses a PTFE filling mold for an elastic composite cylinder rolling body. The PTFE filling mold comprises an upper mold body and a lower mold body which are matched and fixedly connected through a limiting mechanism. A circular block is slidably connected with the lower mold body in a sealed mode, and a threaded hole communicating with a storing groove is formed in the lower endface of the lower mold body and internally provided with a matched threaded rod. The upper end of the threaded rod is rotationally connected with the lower end face of the circular block, and a firstannular cavity is formed in the upper mold body. A water tank is arranged on one sides of the upper mold body and the lower mold body, and the upper end of the water tank is fixedly connected with thefirst annular cavity through a water inlet pipe. The first annular cavity is fixedly connected with a second annular cavity through a connecting pipe, and the second annular cavity is fixedly connected with the side wall of the water tank through a water outlet pipe. According to the PTFE filling mold, the structure is reasonable, the elastic composite cylinder rolling body is conveniently subjected to PTFE filling, meanwhile cooling can be conducted after filling, and the mold is not polluted.

Description

technical field [0001] The invention relates to a PTFE filling mold of an elastic compound cylindrical rolling body. Background technique [0002] The structural form of the elastic compound cylindrical roller bearing is to embed PTFE (polytetrafluoroethylene) material in the hollow deep cavity rolling body to form an elastic compound cylindrical rolling body. Since the rolling elements of elastic composite cylindrical roller bearings are easier to deform than the solid cylindrical rolling elements, under the same load, the contact half-width between the rolling elements and the raceway increases, and the contact stress decreases accordingly; compared with the solid cylindrical rolling elements, The force condition of the elastic composite cylindrical rolling element is obviously improved, especially the bending stress of the inner hole of the rolling element is reduced, so the fatigue resistance of the bearing is enhanced, and the safe service life is prolonged. When manuf...
