Mounting cylindrical hole aligning roller bearings method <br><br>cylindrical hole aligning roller bearing with two rows of spherical rollers, the outer ring has a common concave spherical raceway, the bearing inner ring with two axis tilt angle of the concave raceway , The center of curvature of the outer ring raceway is consistent with the center of the bearing. <br><br>Cylindrical bore spherical roller bearings are installed so that the bearing bore and the center line of the shaft coincide. The skew of the bearing relative to the shaft is not only difficult to install, but also causes indentation, bending of the journal and even fracture of the inner ring of the bearing. Where the press is missing or cannot be used, the bearing can be installed with an assembly sleeve and a hammer. The hammering force should be evenly transmitted to the entire circumference of the end surface of the bearing ring, so the hammered end surface of the assembly sleeve should be made spherical. The inner ring and shaft are loosely fitted, and the outer ring of the bearing is tightly fitted with the housing hole. The bearing can be pressed into the housing first, then the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the housing hole. The outer ring and the housing hole are tightly fitted, and the bearing inner ring and shaft. The end face of the assembly sleeve should be made into a ring that can simultaneously compress the end face of the inner and outer rings of the bearing, or a disk and assembly sleeve can be used to transmit the pressure to the inner and outer rings at the same time, and press the bearing into the shaft and the housing. This kind of installation method is particularly suitable for the installation of self-aligning radial spherical bearings. It should be determined according to the structure, size and matching nature of the bearing with the bearing. The pressure of the device and assembly should be directly applied to the end face of the tightly matched ring, the device and assembly method of the bearing. The pressure cannot be transmitted through the rolling elements, because it will cause indentation on the bearing's working surface, affect the normal operation of the bearing, and even cause the bearing to be damaged. The parts such as the bearing bracket, sealing ring, and dust cover are easily deformed, and the pressure of installing or disassembling the bearing cannot be applied to these parts.

安装圆柱孔调心滚子轴承的方法 <br><br>圆柱孔调心滚子轴承具有两列球面滚子，外圈有一个共同的凹型球面滚道，内圈有两条与轴承轴线倾斜一角度的凹型滚道，外圈滚道的曲率中心与轴承中心一致。<br><br>圆柱孔调心滚子轴承安装时要使轴承孔和轴的中心线重合。轴承相对轴歪斜不只装置困难，而且会造成压痕、轴颈弯曲甚至会使轴承内圈断裂。缺少或不能使用压力机的地方，可以用装配套管和小锤安装轴承。锤击力应均匀的传到轴承套圈端面的整个圆周上，因此装配套管受锤击的端面应制成球形。内圈与轴为较松配合，轴承外圈与壳体孔为紧配合。可将轴承先压入壳体中，这时装配套管的外径应略小于壳体孔的直径。外圈与壳体孔都是紧配合，轴承内圈与轴。装配套管端面应做成能同时压紧轴承内外套圈端面的圆环，或用一圆盘和装配套管，使压力同时传到内外圈上，把轴承压入轴上和壳体中。此种装置方法特别适用于能自动调心的向心球面轴承的装置。应根据轴承的结构、尺寸大小和与轴承部件的配合性质而定。装置、装配的压力应直接加在紧配合的档圈端面上，轴承的装置、装配方法。不能通过滚动体传递压力，因为这样会在轴承工作外表造成压痕，影响轴承正常工作，甚至会使轴承损坏。轴承的坚持架、密封圈、防尘盖等零件很容易变形，装置或拆卸轴承的压力不能加在这些零件上。

Method of installing cylindrical hole self aligning roller bearing<br>The cylindrical hole self-aligning roller bearing has two rows of spherical rollers, the outer ring has a common concave spherical raceway, the inner ring has two concave raceways with an angle of inclination to the bearing axis, and the curvature center of the outer ring raceway is consistent with the bearing center.<br>When installing the cylindrical hole self-aligning roller bearing, make the bearing hole coincide with the center line of the shaft. Bearing relative shaft deflection is not only difficult to install, but also causes indentation, journal bending and even inner ring fracture. Where the press is missing or cannot be used, the assembly sleeve and small hammer can be used to install the bearing. The hammering force shall be evenly transmitted to the whole circumference of the end face of the bearing ring, so the hammered end face of the assembly sleeve shall be spherical. The inner ring is loose fit with the shaft, and the bearing outer ring is tight fit with the housing hole. The bearing can be pressed into the shell first, at this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the shell hole. Outer ring and housing hole are tight fit, bearing inner ring and shaft. The end face of the assembly sleeve shall be made into a ring which can compress the end face of the inner and outer rings of the bearing at the same time, or a disk and the assembly sleeve shall be used to transmit the pressure to the inner and outer rings at the same time and press the bearing into the shaft and the shell. This device method is especially suitable for the device of centripetal spherical bearing which can adjust the center automatically. It shall be determined according to the structure, size and matching property of bearing parts. The pressure of the device and assembly shall be directly applied to the end face of the tight fitting gear ring, the device and assembly method of the bearing. It is not allowed to transfer the pressure through the rolling element, because this will cause indentation on the working surface of the bearing, affect the normal operation of the bearing, and even damage the bearing. The sticking frame, sealing ring, dust cover and other parts of the bearing are easy to deform, and the pressure of the device or the dismounted bearing cannot be added to these parts.<br>
