Abstract

The invention relates to a needle roller bearing sealing ring press-fitting mold. The needle roller bearing sealing ring press-fitting mold comprises a bottom plate, a locating sleeve and a press-fitting punch. A bearing locating mandrel is arranged on the bottom plate. The bearing locating mandrel is sleeved with a needle roller bearing outer ring to be subjected to press-fitting. The locating sleeve is arranged on the needle roller bearing outer ring to be subjected to press-fitting. The middle of the locating sleeve is provided with a big-end up taper hole. An opening of the bottom of the taper hole corresponds to an opening of a sealing groove of the needle roller bearing outer ring to be subjected to press-fitting. A sealing ring is arranged in the taper hole of the locating sleeve. The head of the press-fitting punch is arranged in the taper hole and moves up and down in the taper hole. According to the needle roller bearing sealing ring press-fitting mold provided by the invention, the sealing ring is guided into the opening of the sealing groove, and assembly on the sealing ring is realized; the sealing ring can be guided into the bearing sealing groove smoothly without damage to the sealing ring, and the assembly efficiency is substantially improved.

Description

technical field [0001] The invention relates to the field of needle roller bearing processing, in particular to a pressing mold for sealing rings of needle roller bearings. Background technique [0002] Needle roller bearing sealing rings are generally assembled manually in the case of loose fit of the conventional outer diameter, but when the outer diameter of the sealing ring is greatly different from the size of the outer ring notch, it is difficult to install the sealing ring into the sealing In the ring groove, and the sealing ring is easy to be damaged during the assembly process. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a press-fitting die for the sealing ring of a needle roller bearing. Through the gradual shrinkage of the outer diameter of the sealing ring, it is guided into the sealing notch to realize the assembly of the sealing ring, and the sealing ring can be smoothly introduce...
