调心球轴承

SBC Self-Aligning Ball Bearing 调心球轴承.pdf

调心球轴承是二条滚道的内圈和滚道为球面的外圈之间，装配有圆球状滚珠的轴承。 外圈滚道面的曲率中心与轴承中心一致，所以具有与自动调心球轴承同样的调心功能。在轴、外壳出现挠曲时，可以自动调整，不增加轴承负担。调心滚子轴承可以承受径向负荷及二个方向的轴向负荷。径向负荷能力大，适用于有重负荷、冲击负荷的情况。内圈内径是锥孔的轴承，可直接安装。或使用紧定套、拆卸筒安装在圆柱轴上。保持架使用钢板冲压保持架、聚酰胺成形保持架及铜合金车制保持架。 调心球轴承有圆柱孔和圆锥孔两种结构，保持架的材质有钢板、合成树脂等。其特点是外圈滚道呈球面形，具有自动调心性，可以补偿不同心度和轴挠度造 调心球轴承成的误差，但其内、外圈相对倾斜度不得超过3度。可承受较大的径向载荷，同时也能承受一定的轴向载荷。该类轴承外圈滚道是球面形，故具有调心性能，当轴受力弯曲或倾斜而使内圈中心线与外圈中心线相对倾斜不超过1°～2.5°时，轴承仍能工作。 调心球轴承内孔有圆柱形和圆锥形两种。圆锥形内孔的锥度为1：1 2或1：30。为了加强轴承的润滑性能，在轴承外圈上加工环形油槽和三个油孔。

elf-aligning ball bearing is two race between inner ring and groove for spherical outer ring, equipped with balls of ball bearings. On the surface of the outer ring raceway curvature center and bearing center consistent, so with automatic self-aligning ball bearing the same tone heart function. In there was a deflection axis, a hood, can automatically adjust, not to increase the bearing burden. Spherical roller bearings can withstand radial load and two direction axial load. Large radial load capacity, suitable for heavy load and impact load. Inner circle diameter is tapered bore the bearing, it can be installed directly.Or the use of set cover, remove the cylinder installed on the cylinder axis. Keep rack stamping steel cage, polyamide forming keep frame and copper alloy car cage. Self-aligning ball bearing with two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins. Characterized by outer ring raceway is spherical shape, have so can compensate concentricity and deflection built into the error of the self-aligning ball bearing, but it shall not exceed 3 degrees between inner ring and outer.May withstand the bigger radial load, and at the same time also can absorb a certain amount of axial load. This kind of bearing outer ring raceway is spherical shape, so has a self-aligning performance, when the axial stress bending or leaning and make the center line of the center line of the inner ring and outer ring relative tilt is not more than 1 ° ~ 2.5 °, bearing can still work. Self-aligning ball bearing inner hole has two kinds of cylindrical and conical. Conical taper of inner hole of 1:1 2 or 1:30. In order to strengthen the bearing lubrication performance in annular groove on the bearing outer ring and three oil hole.
