NSK bearings (professor pointed out: especially the rolling bearing) is a layout of the strap holder and the holder without the bracket. The large bearings usually require a large load; often without the bracket; The raceway is filled with tumblers. Most small and medium sized rolling bearings are fitted with a frame.
In the NSK bearing in the processing flow; how the outer ring, inner ring, roll body and the support frame of the bearing are assembled together. Briefly speaking, the inner ring of the bearing is placed first, the inner ring is placed on the side, and then placed Rolling body (put it aside), then adjust the orientation of the roll body, and finally, put on the frame. Now we all know it; in the processing of the bearing, there is also a shelf to participate; then the first thing to do with the bearing is to å•¥What about the effect?
The effect of the shelf is:
1. Guide and roll the rolling body to roll on the correct raceway.
2, adhere to the frame will be separated from the rolling body at equal distance; evenly distributed on the circumference of the raceway to prevent the rolling bodies from colliding and conflicting during operation.
3. In the separate bearing; combine the roll body and a ferrule; to prevent the roll from falling.
The bearing is called a window; it is used to block and guide the rolling body; the pocket gap allows the holding frame to have a certain amount of activity in the radial and axial directions; the total radial amount of movement is called the gap of the holding frame. A variety of layout types, shapes are messy. Stick to many equidistant pockets on the shelf; pocket shapes are spherical, circular, elliptical, rectangular and toothed; the scale is larger than the roll scale; the difference between the two is pocket Void; sometimes the connection between the window and the frame is called the girders; it serves to connect and add the strength of the frame.
NSK bearing application and attention: Rolling bearings are fine parts; their use must be carried out in a stable manner. No matter how high-performance bearings are used; if not used properly, it will not achieve the expected high performance. The following matters are as follows:
(1). Adhere to the bearing and its surrounding sanitation. Even small dust that can't be seen by the eyes will affect the bearing. Therefore, it is necessary to adhere to the surrounding sanitation; so that the dust does not invade the bearing.
(2). Use it cautiously. In the application, it will give a strong impact on the bearing; it will cause scars and indentations; it will be the cause of the incident. Under severe conditions; it will crack and crack; so it is necessary to pay attention.
(3). Use the right things to do. Prevent the replacement of existing things; it is necessary to use the right things, such as special sleeves, presses, etc.
(4). Pay attention to the corrosion of the bearing. When operating the bearing; the sweat on the hand will become the cause of rust. Pay attention to the operation with clean hands; best put gloves as much as possible.
(5). Do not disassemble the bearing packaging until the device preparation work is completed; avoid contamination.
