The application relates to the field of mechanical
lubrication, in particular to a bearing
grease injection mold and a
grease injection method, which comprise a bearing
grease injection mold, the mold comprising a grease injection mold, a radial positioning piece and a grease injection ring, one end of the grease injection mold is a fitting end which is fitted with a bearing end face, the other end is provided with a grease injection groove, a grease injection flow channel is arranged at the bottom of the groove; the radial positioning piece is connected with the grease injection mold and can be matched with the inner
diameter / outer
diameter of the bearing; the grease injection ring is connected with the fitting end, one end of the grease injection ring away from the fitting end can be embedded between the inner ring and the
retainer or the outer ring and the
retainer of the bearing, the grease injection ring is provided with a grease injection hole which is communicated with the grease injection flow channel, the grease injection ring further comprises an embedding ring, an inserting ring and the like, and the application further comprises a bearing grease injection method, such as A / B surface grease injection and the like. The application achieves the technical effects of accurately and efficiently injecting grease into the bearing, ensuring that the grease injection amount meets the requirements and improving the lubricating effect of the bearing.
