Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0018] The double row ball bearing assembly process is to complete the assembly in the following order after assembling the steel ball 4 with the inner ring 1 and the outer ring 2:
[0019] (1) Assemble the cage 3 on one of the rows of steel balls;
[0020] (2) cleaning;
[0021] (3) Finished product inspection;
[0022] (4) drying;
[0023] (5) inject grease 6 between two rows of steel balls from the outside of another row of steel balls with a grease injection mold;
[0024] (6) Assemble the cage on the other row of steel balls;
[0025] (7) Assemble sealing rings between the two ends of the inner ring and outer ring.
[0026] Wherein: described grease injection process mold 5 such as figure 1 As shown, it has a mold body 51, on which a fat storage chamber 52, a connecting portion 53 communicating with the fat storage chamber 52 and a forward...

The invention relates to a dual-row ball bearing assembling process which is characterized in that after steel balls, an inner ring and an outer ring are assembled together, the assembly is completed according to the following sequence: a retainer and a grease injection process mould for cleaning, finished product inspection and drying are assembled on one row of steel balls; grease is injected from the outside of the other row of steel balls into the two rows of steel balls; the other retainer is assembled on the other row of steel balls; and a sealing ring is assembled between two ends of the inner ring and the outer ring. By changing the assembling process, the grease is injected between the two rows of steel balls; when compared with the same products under the same condition, the dual-row ball bearing with the assembling process obviously improves the grease leakage rate, and controls the grease leakage rate within 1%. In addition, the special grease injection process mould has the advantages of simple structure and convenient operation and can directly inject the grease between the two rows of steel balls in a uniform and accurate way.
Description
technical field [0001] The invention relates to a bearing assembly process, in particular to a double-row ball bearing assembly process. Background technique [0002] The existing double-row ball bearing assembly process is to assemble the steel balls with the inner ring and the outer ring, press the double-sided cage in sequence, clean, inspect the finished product, dry, inject grease, and press the sealing ring. The grease of the assembled bearing is injected on the outside of the two rows of steel balls, that is, between the steel balls and the sealing ring. The test for grease leakage cannot meet the customer's requirements (the customer's requirement for the bearing grease leakage rate must be less than 5 %), the actual test grease leakage rate is about 8% to 9%. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect of high grease leakage rate of the bearing assembled ...
