Bearing use guide

Bearing use guidelines in the use of bearings, bearing assembly and shaft and fixed, improper assembly can lead to bearing damage, caused by sound, vibration and fever, shorten the service life of the product. In addition, the need to pay attention to the handling and storage. When using the adhesive assembly please understand product features, and pay attention to the operation method and so on, the following separately using bearing and matters needing attention. 1, ball bearing for precision parts, need to avoid foreign bodies to enter. Please attach great importance to the use environment of cleanliness. 2, bearing and shaft, the fixed seat available between a variety of methods, fixed, when assembly, please pay attention to the following matters. No matter how to 'match' must be on the bearing and shaft, bearing, and the center of the fixed seat for vertical installation. The interference with the quantity, to 'cooperate' side of the inner ring and outer ring exert pressure into the vertical force. In addition, the pressure into ShiJiaJing load, and do not exert impact load with a hammer, etc. Toward a direction of bearing Angle on inner and outer gap is too large torque load, load location or at the wrong style, bearing internal may produce indentation. For dust cover, sealed type, do not impose load on shield and sealing. 3, shaft and fixed operation, if there is foreign body attached shaft and fixed, the assembled bearing will not be properly installed and lead to axis deviation. Axis and fixed injury occurs. In addition, the axis deviation pressure under the condition of pressure, can lead to shaft and fixed cause a new injury. Ball bearing inner and outer ring wall thickness ( The thickness of the section) Very thin, 'cooperate' with amount of interference, the shape of the shaft and fixed directly by the ball bearings inside and outside circle axis channel slot replication. Especially roundness is low and flat marks, damage, inside and outside the circle is easy to deformation, and leads to the noise and shorter service life and navigation wurui remind you must pay attention to. Equipped with 4, handling after assembly, shaft bearing of motor bulge on the rear axle assembly is still prominent, impose excessive load and impact load on axle, bearing internal may produce indentation. In addition, if applying vibration may produce microtremor wear trace. 5, ball bearings and the shaft and fixed when using the binder is fixed, please pay attention to the following matters. Bond before wiping daub is on the ball bearing outer rust-proof oil, please wipe with clean cloth with alcohol, etc. But alcohol such as too much will bring foreign body together into bearing, so please avoid too many dip. Bonding job, please try to control the amount daub, pay attention to avoid the binder into the bearing inside. Especially anaerobic adhesive and uv sclerosis type binder has entered into the bearing internal finish assembly is not an immediate problem, but with the increase of using time, the problem will gradually. Please refer to figure 19 - 4 apply the necessary amount, avoid excessive blotted out. In addition, equipped with binder tank, use very convenient. When installing the bearing must pay attention to ensure that every step is correct, to make the bearing of normal use.
