And are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation and, therefore, should not be taken to be limiting of the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The grease injection tool for simultaneously injecting grease into a bearing channel and a dust-proof groove as shown in fig. 1 or 2 comprises a grease injection tool body 100, wherein the grease injection tool body 100 comprises first to third cylindrical cavities 110, 120 and 130 which are connected with each other, the diameters of the first to third cylindrical cavities 110, 120 and 130 are gradually increased, and the first cylindrical cavity 110 is connected with the second cylindrical cavity 120 through a first step surface 111.
A first annular convex part 140 is arranged on the end surface of the first cylindrical cavity 110, and a plurality of channel grease injection outlets 141 are arranged on the first annular convex part 140. The grease injection outlet 141 of the channel is arranged on the contact surface of the first annular convex part 140 and the bearing 200 at intervals through the convex end 142.
A second annular convex part 150 is arranged on the inner side of the first annular convex part 140, and a dustproof groove grease injection outlet 151 is arranged on the second annular convex part 150.
The third annular protrusion 160 is axially disposed inside the second annular protrusion 150, and a bearing clamping portion 170 for clamping the inner ring 210 of the bearing 200 is disposed between the second annular protrusion 150 and the third annular protrusion 160.
