Deep Groove Ball Bearings Meet The Requirements

Deep Groove Ball Bearings Meet the requirements

Deep groove ball bearings should be installed with gasoline or kerosene before cleaning, dry use, and to ensure good lubrication, deep groove ball bearings are generally used grease lubrication, can also be used oil lubrication. When using grease lubrication, should use no impurities, anti-oxidation, rust, extreme pressure and other excellent performance of the grease. Grease filling volume for the deep groove ball bearings and deep groove ball bearing box volume of 30% -60%, should not be too much. Deep groove ball bearing with seal structure has been filled with grease, the user can directly use, can not be cleaned.

Deep groove ball bearings installed, the deep groove ball bearings must be in the circle on the circumference of the circumference of the application of equal pressure, the ring press, not hammers and other tools directly hit the deep groove ball bearing face, so as not to damage deep groove ball bearings The In the case of smaller interference, can be used at room temperature with a sleeve to suppress the deep groove ball bearing ring end face, with the head of the sleeve, through the sleeve will be evenly pressed into the ring. If the installation of large quantities, can use hydraulic press. When pressed into, should ensure that the outer ring end face and the shell shoulder face, inner ring end and shaft shoulder face compression, do not agree with a gap.

1. Measure the size of the shaft and the deep groove ball bearing hole to determine the precision of the deep groove ball bearing with the following requirements: the inner ring and the shaft to take the interference fit, the interference 0 ~ +4μm (at light load, high Precision 0); outer ring and deep groove ball bearing hole to take the gap with the gap of 0 ~ +6μm (but in the free end of the deep groove ball bearings using angular contact ball deep groove ball bearings, but also increase the gap) Axis and seat surface roundness error of less than 2μm, deep groove ball bearings used in the end of the parallelism of 2μm below the shoulder end of the face of the outer surface of the beating in the 2μm below; deep groove ball bearing hole on the axis Of the beating below 4μm; the front end of the main shaft facing the axis of the beating below 4μm. 2. Fixed deep groove ball bearings on the shaft to install: the deep groove ball bearings with clean cleaning kerosene for thorough cleaning, for grease lubrication, the first containing 3% to 5% of the organic solvent into the deep groove ball (For deep groove ball bearing space volume of 10% to 15%); heating deep groove ball bearings to raise the temperature of 20 ~ 30 ℃, and then use the grease to fill the deep groove ball bearings, With the hydraulic press to the deep groove ball bearing into the shaft end; the adapter sleeve on the shaft and with the appropriate pressure against the deep groove ball bearing end to its axial positioning; the spring scale tape rolled in the deep groove ball bearing outer ring (Even if the deep groove ball bearings are correct), the preload can be changed due to the deformation of the mating or cage, by checking the starting torque with the method of measuring the starting torque.
