Roller accessories installed five points to note
First, the installation should be able to ensure that the roller parts to play their normal value.
Second, when installed to exert a certain pressure to the inner ring to the shoulder pressure, because the roller bearing parts after cooling its width will also be a certain degree of contraction, so after cooling should be best with a very thin gauge Test for testing, whether the end surface of the inner ring and the gap between the shoulder.
Third, the installation of roller accessories found that the temperature has reached the heating requirements, you must immediately start to install, so as to avoid cooling and installation difficulties.
Fourth, the roller accessories bearing heating to master the temperature, not too high, otherwise it will cause bearing damage. But also can not be too low, otherwise there will be insufficient ring expansion of the situation.
Fifth, pay attention to the external environment of the flowers, the best situation according to the field to select the appropriate roller accessories installation program, in order to roller accessories installation work can proceed smoothly.
Stamping bearings: the most representative of the press bearings, versatile, can withstand radial load and two-way axial load; for high-speed rotation and require low noise, low vibration occasions; with steel plate dust cover or rubber seal seal Type bearing with pre-filled with the amount of grease; outer ring with a snap ring or flange bearings, which is easy to axial positioning, and easy to install the shell; the maximum load bearing size and standard bearing the same, There is a filling groove in the outer ring, which increases the number of balls and increases the rated load.
Through the punch and die on the plate, strip, pipe and profiles and other external force, so that the plastic deformation or separation, in order to obtain the required shape and size of the workpiece forming method, the workpiece is stamping parts.
Stamping presses are formed by the application of external force to the plates, strips, pipes and profiles by means of presses and dies, resulting in plastic deformation or separation, to obtain the required shape and size of the workpiece (stamping bearing stamping parts) forming processing methods. Stamping and forging belong to the same plastic processing (or pressure processing), collectively known as forging. Stamping of the blank is mainly hot-rolled and cold-rolled steel and strip.
The worlds steel, 60 to 70% of the plate, most of which is made by pressing the finished product. The car body, the chassis, the fuel tank, the radiator piece, the boiler steam drum, the vessel shell, the electrical machinery, the electrical appliances iron core silicon steel sheet and so on are all stamping processes. Instruments, household appliances, bicycles, office machinery, living vessels and other products, there are a large number of stamping parts.
Stamping bearings and castings, forgings, compared with a thin, uniform, light, strong features. Stamping can be made with other methods difficult to manufacture with ribs, ribs, rolling or flange of the workpiece to improve its rigidity. As a result of precision molds, workpiece accuracy up to micron-level, and repeat high precision, the same specifications, you can punch out the hole, convex and so on.
Stamping bearings are generally no longer machined, or require only a small amount of cutting. Hot stamping parts of the precision and surface conditions lower than the cold stamping parts, but still better than castings, forgings, cutting less.
