Which a few kinds bearing can be divided into? Each have what use?

Which a few kinds to ask bearing can be divided into? Each have what use? Answer questions 1, deep groove ball bearings, deep groove ball bearing structure is simple, using the bento, is the largest, consumption quantity's most widely used type of bearings. It mainly USES the radial load, also can accept certain axial load. When bearing radial clearance increases, with the function of the angular contact bearings, can accept the larger axial load. 2, self-aligning ball bearings, self-aligning ball bearing is just for two columns, there are two inner ring raceway, the outer ring raceway is spherical shape, with automatic self-aligning performance. Able to automatically compensate due to the shaft alignment errors caused by rao curve and surface deformation, suitable for bearing seat hole can guarantee strict alignment of parts. The main accept radial load bearing, in the acceptance of the radial load at the same time, also can accept a small amount of axial load, usually not used to accept pure axial load, such as accept pure axial load, as long as a list of just the ball bearing. 3, angular contact ball bearings, angular contact ball bearing limit rotational speed is higher, can be accepted by the load and axial load at the same time, also can accept pure axial load, its axial load to resolution by the contact Angle, and with the increase of contact Angle increases. Four roller, cylindrical roller bearing, cylindrical roller bearings are usually guided by a bearing ring two guard, adhere to the frame. Roller and guide ring of an assembly, but with another bearing ring, separation are bearing separation. This bearing assembly, disassembly match bento, especially when the request. The outer ring and the shaft. When the shell is interference fit appeared more advantages. Such common used only for radial load bearing, as long as the inside. Outer ring with penal single bearing can accept smaller constant axial load or larger intermittent axial load. 5, spherical roller bearing self-aligning roller bearing has two columns of roller, it is mainly used for radial load, at the same time also can accept any direction axial load. This kind of bearing radial load can be high, especially suitable for overloading or under vibration loading work, but can't accept pure axial load; Adjustable heart performance is good, can be compensated with the bearing error. 6 taper roller bearings, tapered roller bearing mainly applies to accept in order to mainly consisting of radial load and axial load, and the big cone Angle tapered roller bearing can be used to accept is given priority to with axial load, axial load. This kind of bearing to bearing separation type, its circle ( Tapered roller and adhere to the frame) And the outer ring can device respectively. In the process of the device and used to adjust the bearing by the clearance and axial clearance, preloaded device can also be made. 7 thrust ball bearing, thrust ball bearing is a kind of separation type bearing, shaft ring 'seat to just the ball and stick to ` component separation. Shaft is made to match the shaft ring, sit circle is to match the bearing hole of the ring, and there are gaps between shaft. Smoking to hand thrust ball bearing axial load, one-way thrust ball bearings can only accept a room of axial load, two-way thrust ball bearings can accept two direction axial load. Thrust ball accept not limit axial warp to move, limit rotational speed is low. One-way thrust ball bearing can limit the one direction of the axis and shell of the axial displacement, two-way bearing can limit the axial displacement of two direction. 8, thrust roller bearing thrust spherical roller bearing is used to accept the axial load of shaft. By the combined load, but by the load shall not surpass 55% of the axial load. Compared with other thrust roller bearings, the bearing friction factor is low, high speed, and has the heart to. Type 29000 type roller for asymmetric spherical roller bearing, can reduce the relative sliding roller and race in the work, and roller is long. Large diameter, roller number load capacity is big, smooth, usually adopt oil available fat smooth individual low speed conditions. While selecting a design, should be preferable. 9, needle roller bearings, needle roller bearing with thin and long ( For 3 ~ 10 times the diameter of the roller length, average diameter is not more than 5 mm) And radial structure is compact, its inner diameter size and load ability at the same time, with other types of bearing outside diameter to a minimum, especially with the limited size of the radial gear bearing structure. On the basis of using the place is different, can be used without inner ring of the bearing or needle and adhere to the frame components, at this time to suit the bearing of the shaft neck looks and the shell hole they directly as a bearing. Rolling outside appearance, to adhere to the load ability and operation performance and you have the same ring bearing, axis or shell hole hardness raceway appearance. Machining precision and appearance and appearance quality should be as a bearing ring raceway. These bearings can only accept the radial load. 10, insert ball bearing insert ball bearing unit by the two sides with a seal of outer spherical ball bearing and casting ( Or steel plate stamping) Bearing seat. The internal structure of the external spherical ball bearing and deep groove ball bearings are the same, but this kind of bearing inner ring width in the outer ring. Outer ring is cut surface, spherical surface and concave spherical match automatically self-aligning bearing seat. Usually these bearings have a space between the inner hole and shaft, with the top silk, eccentric sleeve or be a set of bearing inner ring is fixed on the shaft, and with the rotation axis. Arrange ushering bearing structure is compact, loading and unloading bento, seal is perfect, suitable for simple support, commonly used in mining. Metallurgy. Agriculture. Chemical industry. Textiles. Printing and dyeing. Walks machinery, etc.
