Thrust ball bearing installation characteristics in jiaxing bearing group sales co. , LTD

There is rotational, have HRB bearing ( ) Thrust ball bearing installation characteristics in jiaxing bearing group sales co. , LTD. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. A cage and steel ball bonding quality control, the other is a nominal highly T control after bearing assembly. Conventional is to prevent imported bearing parts. After pressing demands steel ball in the pocket hole flexible rotation, but can not fall off from the pocket hole, and technical discipline inspection steel ball in the hole in the pocket up momentum. Entities cage stamping pressure too deep will make small steel ball up momentum, and bumps on the stamping connection with cage too little and strength is insufficient, prone to falling phenomenon, cause maintains a scrap. To prevent mixing of phenomenon, namely loading into a set of bearing clay a set of trapped or are shaft is a circle. Or set of assistive tools will usually smoke ring, distinguish, or before sampling nominal height with inner diameter gauge inspection, in order to check the inner diameter is convenient, put under the seat, shaft ring above. If a cabinet inside have obvious quench heating oxidation color or not after grinding, it should not be necessary to test diameter, can obviously see the difference between shaft and seat, not easy to mix. Thrust ball bearing assembly for nominal high T measure, after confirmation is best qualified. , measured in height or the difficult pieces of calibration, and measured load, bearing rotating if ten times, it is important to achieve the minimum level. According to the standard, fag bearing total deviation of nominal high T direction or negative, so the size deviation also to lose the direction. If the parts meet the requirements for entry to assembly, or after the set of highly T not super bad. Otherwise, you should use ball diameter size ( Increase or decrease) For matching. But using steel ball is too big or too small, not only will affect the quality of steel ball and cage's pressure, at the same time, it will change the steel ball and raceway contact state, affect the service life of bearing. So only grinding in strict accordance with the size deviation processing, assembly work just now turns on, and no separation or set on the surface of the groove of the base height size deviation, can achieve the goal of any accessory. Thrust bearing and shaft with transition fit, seat and the general for clearance fit the bearing hole ( See here, you must also agree to my opinion) 。 The center axis of the two-way thrust bearing ring should be fixed on the shaft, to prevent the relative to the axis of rotation. Thrust bearing installation method, usually is the situation of the axis of rotation, so the inner ring cooperate for win cooperate with shaft, with the bearing outer ring and bearing chamber for clearance fit. Installing a thrust bearing, shaft circle shall be checked and verticality of shaft centerline. Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline. Box shell hole deep, also can use extended dial gauge head test. Thrust bearing installed correctly, the seat can automatically adapt to roller rolling, to ensure that the rolling elements located at the top and bottom ring raceway. If installed backwards, bearing not only don't work properly, and the matching surface will badly worn. Due to axial ring and seat and the difference is not obvious, the assembly should be extra careful, do not make a mistake. In addition, the seat of thrust bearing and the bearing holes should also be left between 0. 20. 5 mm clearance to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, will cause bearing severe damage. Installing a thrust bearing, shaft circle shall be checked and verticality of shaft centerline. Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline. Box shell hole deep, also can use longer dial gauge head test thrust bearing installed correctly, the seat can automatically adapt to roller rolling, to ensure that is located in the upper and lower roller ring raceway. If installed backwards, bearing not only don't work properly, and the matching surface will badly worn. Due to axial ring and seat and the difference is not obvious, the assembly should be extra careful, do not make a mistake. In addition, the seat of thrust bearing and the bearing holes should also be left between 0. 20. 5 mm clearance to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, will cause bearing severe damage.
