Vibration motor imported bearing installation skills

When the imported bearing replaces the vibration motor, the effect is different, and the same bearing as the original model must be used, and the effect in this aspect has a better meaning, so that it can be used in this respect. Reflects better results. First introduce the installation of imported bearings from the following situations.
    When replacing a new bearing with a vibrating motor, the same bearing as the original model must be used.

    1) Wash the bearing with kerosene, press it into the bearing seat, fill the roller of the outer ring of the bearing with Shell No. 3 lithium base grease to two-thirds full, apply evenly with the net hand, install the bearing gland, and apply the bolt The fastening bolt of the anti-loosening rubber presses the bearing gland;

    2) The bearing is a cylindrical roller bearing with a detachable inner casing. The bearing should be placed on the rotating shaft and placed in place;

    3) Mount the bearing housing on the casing. If there is grease grease hole, it must be aligned. Pressing the bearing block with the fastening bolts of the anti-loosening rubber;

    4) The inner and outer eccentric blocks are mounted on the rotating shaft and are in place. If there is an axis key, the shaft key should be inserted into the keyway and then the outer eccentric block should be installed, and the shaft can be mounted on the rotating shaft with the retaining ring;

    5) Tightly fix the eccentric block fastening bolts and turn the adjustable eccentric block to the angular position before the unloading and tighten the fastening bolts. After the above assembly is completed, the shaft should have a certain axial movement;

    6) The protective cover on both ends of the upper vibration motor is fastened with screws.

The imported bearings have certain changes to the installation form of the vibration motor and other aspects of the performance, and the form considered from different angles has a certain change effect, and slowly the installation situation of all aspects has also been I understand it.

How to properly install the thrust bearing

    The thrust bearing is to be inspected after installation. When installing the thrust bearing, first check the verticality of the shaft ring and the centerline of the shaft. The test method is: fix the dial gauge on the end surface of the casing, so that the contact of the watch top rotates the bearing on the bearing shaft raceway, and then observe the dial gauge pointer. If the shaft ring and the shaft center line are not perpendicular, then the pointer Hemiplegia. The pointer of the dial gauge has a relatively long length. If the box hole is deep, you can also choose to use the extended dial gauge for inspection.

    The seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located in the upper and lower ring raceways, indicating that the thrust bearings are installed correctly. If the thrust bearing is reversed, if this happens. The bearings are not working properly and the mating surfaces of the bearings are subject to severe wear. The difference between the shaft ring and the seat ring is not very obvious, so care should be taken in the assembly. Moreover, there should be a gap of 0.2-0.5mm between the seat ring of the thrust bearing and the bearing seat hole. This gap is used to compensate for the error caused by inaccurate machining and installation. If there is an accident, the bearing sleeve is in operation. When the center of the circle is offset, this gap can make a big difference, ensuring that it automatically adjusts to avoid contact friction and keep the bearing running normally. If there is no such gap, it will cause severe damage to the bearing. The bearing is damaged and cannot be used.
