Abstract

本发明涉及调心滚子轴承技术领域，具体的说是新型结构的冲压保持架调心滚子轴承；圈与内圈间设有保持架，滚子位于保持架上，保持架上设有中隔圈，所述保持架上设有第一导引面和第二导引面，切坡位于第一导引面和第二导引面之间，保持架上设有锁口；其有益效果是：在锁口处增加切坡，并增高锁口高度，避免切坡与滚子的接触，延长使用寿命，同时还能够达到增加存油量的目的，从而更好的润滑滚道，在切坡两侧设有导引面，增加滚子运行的平稳度，减小滚子的磨损。

Description

新型结构的冲压保持架调心滚子轴承
技术领域    本发明专利涉及调心滚子轴承技术领域，具体的说是新型结构的冲压保持架调心滚子轴承。
背景技术   随着国内外轧机、鼓风机、矿山、港口、工程机械等领域快速发展，需要提高机械的生产效率，为适应设备的高承载、高可靠性、高速的要求，势必要求高速、高承载、高可靠性的轴承与之匹配；目前，国内使用的调心滚子轴承，大部分采用铜保持架，几年有的采用钢板冲压保持架，但转速也不能太高。转速过高，中挡圈零件磨损严重。为此研发一种新结构的带有冲压保持架的调心滚子轴承，具有高承载、高精度、高可靠性的轴承，成为当务之急。
发明内容    鉴于已有技术存在的缺陷，本发明的目的是提供一种新型结构的冲压保持架调心滚子轴承。
为实现上述目的，本发明所采用的技术解决方案是：新型结构的冲压保持架调心滚子轴承，外圈与内圈间设有保持架，滚子位于保持架上，保持架上设有中隔圈，所述保持架上设有第一导引面和第二导引面，切坡位于第一导引面和第二导引面之间，保持架上设有锁口。
所述锁口高度高于滚子直径30%。
所述保持架的回转中心位于锁口高度点、滚子与保持架两端的接触点确定的圆的圆心。
所述切坡的坡面与滚子母线相切。
新型结构的冲压保持架调心滚子轴承，其有益效果是：在锁口处增加切坡，并增高锁口高度，避免切坡与滚子的接触，延长使用寿命，同时还能够达到增加存油量的目的，从而更好的润滑滚道，在切坡两侧设有导引面，增加滚子运行的平稳度，减小滚子的磨损。
附图说明
图1是新型结构的冲压保持架调心滚子轴承的结构剖面图；
图2是新型结构的冲压保持架调心滚子轴承的整体外观图；
图3是新型结构的冲压保持架调心滚子轴承的保持架的局部结构图。
附图标记如下：1、外圈，2、滚子，3、保持架，4、中隔圈，5、内圈，6、第一导引面，7、切坡，8、第二导引面，9、锁口。
具体实施方式
根据附图对新型结构的冲压保持架调心滚子轴承具体说明如下：外圈1与内圈5间设有保持架3，滚子2位于保持架3上，保持架3上设有中隔圈4，所述保持架3上设有第一导引面6和第二导引面8，切坡7位于第一导引面6和第二导引面8之间，保持架3上设有锁口9。
所述锁口高度高于滚子直径30%。
所述保持架的回转中心位于锁口高度点、滚子与保持架两端的接触点确定的圆的圆心。
所述切坡7的坡面与滚子2母线相切。
