调心滚子轴承具有两列滚子,主要承受径向载荷,同时也能承受任一方向的轴向载荷。有高的径向载荷能力,特别适用于重载或振动载荷下工作,但不能承受纯轴向载荷。该类轴承外圈滚道是球面形,故其调心性能良好,能补偿同轴度误差。
它有两列对称型球面滚子,外圈有一条共用的球面滚道,内圈有两条与轴承轴线倾斜一角度的滚道,具有良好的调心性能,当轴受力弯曲或安装不同心时轴承仍可正常使用,调心性随轴承尺寸系列不同而异,一般所允许的调心角度为1~2.5度 ,该类型轴承的负荷能力较大,除能承受径向负荷外轴承还能承受双向作用的轴向负荷,具有较好的抗冲击能力,一般来说调心滚子轴承所允许的工作转速较低。
调心滚子轴承按滚子截面形状分为对称形球面滚子和非对称形球面滚子两种不同结构,非对称调心滚子轴承属早期产品,主要是为主机维修服务,新设计主机时则很少选用对称形调心滚子轴承,内部结构经过全面改进设计及参数优化,与早期生产的调心滚子轴承相比,能够承受更大的轴向负荷,这种轴承的运行温度较低,故可适应较高转速的要求,根据内圈有无挡边及所用保持架的不同可分为C型与CA型两种,C型轴承的特点是内圈无挡边和采用钢板冲压保持架,CA型特瑞恩轴承的特点则为内圈两侧均有挡边和采用车制实体保持架。为了改善轴承的润滑, 可向用户提供外圈带有环状油槽和三个油孔的调心滚子轴承,以轴承后置代号/W33 表示。根据用户的要求也可供应带内圈油孔的调心滚子轴承,为了便于客户装卸和更换轴承, 还可提供内孔带有锥度的调心滚子轴承轴承,锥孔锥度为1:12, 以后置代号为K 表示,为了适应特殊用户的要求也可提供内孔锥度为1:30 的轴承,其后置代号为K30。 内孔带锥度的轴承可用锁紧螺母将轴承直接装在锥形轴颈上,也可借助紧定套或退卸套将轴承安装在圆柱形轴颈上。
