The correct way of using the high-speed section such as bearing

High speed section bearing the correct using methods such as: high speed constant cross-section bearing in the mechanical equipment is a very important part of it is also a crucial device of cooperation and adjustment. Here, let's introduce for everybody high-speed device such as a cross section bearing as well as the matters needing attention: such as high speed as well as cooperation and clearance for high-speed section bearing cross-section bearing should be in accordance with the requirements of high precision constant cross-section bearing and according to the requirements of high temperature section such as bearing, so when considering its cooperation and clearance, to consider the following two points: ( 1) From normal temperature to high temperature change and hardness of the scale of the change; （ 2) Under the high speed centrifugal force caused by the force system change and change shape. Therefore, under the condition of high speed, high temperature, from cooperation and try to be stick to uniform the clearance on the selection of bearing accuracy and operating performance, it is difficult. Allow the axial load shall not exceed 20% of the rated dynamic load. In order to keep the device such as a cross section bearing raceway after deformation is small, amount of interference interference cooperation can't get too big, and under the high speed centrifugal force and high temperature thermal expansion, or appearance of the normal pressure offset cooperation. Allow the axial load shall not exceed 20% of the rated dynamic load. Surface lax or make cooperation, thus interference quantity must be on the premise of considering these two factors carefully accounting, useful interference quantity under the constant velocity of the cross section about high-speed bearings may be invalid. If calculation results the opposition is too big, so long as adopt ring under smooth method and static pressure smooth method with two layers of smooth solution, and this plan has the potential to uniform the bearing value of DMN break 3 million mark. High temperature thermal expansion, or appearance of the normal pressure offset cooperation. Arrange ushering bearing is deep groove ball bearing grease seal type bearing with different shapes and combination of high precision components products. Bearing assembly can pass a few bolts to install directly on the body of the mechanical device, with the heart function, can be the supplement of the grease, etc. , is a kind of installation is very simple products. Surface lax or make cooperation, thus interference quantity must be on the premise of considering these two factors carefully accounting, useful interference quantity under the constant velocity of the cross section about high-speed bearings may be invalid. If calculation results the opposition is too big, so long as adopt ring under smooth method and static pressure smooth method with two layers of smooth solution, and this plan has the potential to uniform the bearing value of DMN break 3 million mark. When considering the high-speed section bearing such as clearance not only should consider the above-mentioned factors, and to consider the influence of the axial thermal elongation of clearance, the requirements in the assignments section bearing condition, namely has the best clearance in operating temperature, and the clearance is included, the outer ring groove ball center accurate registration form. Because of the high speed and being cross section bearing down relative sliding and internal conflict, had better not choose to inner and outer ring relative displacement method to adjust the ball along the axial section bearing such as clearance. Considering the interference section bearing of cooperation such as the quantity and clearance, be aware that materials at high temperature becomes soft and easy to deformation characteristics, and often caused by the temperature change of normal temperature to high temperature will be the possibility of permanent deformation. Above is we in the process of high-speed device such as a cross section bearing and to use the matters needing attention.
