Description

空心滚子轴承
技术领域
本发明属于轴承，特别涉及一种大型机械使用的一种空心滚子轴承。
背景技术
轴承是机械中的一种重要部件之一，它的技术性能好坏对机械的性能好坏，使用寿命长短，起到至关重要的作用。不同机械对轴承技术的要求也各不相同。目前对于大型机械要求轴承的承载能力越来越高，因为它关系到使用寿命。目前使用的圆柱、圆锥、球面滚子轴承都是采用直径一样大小的支柱穿过滚子一端，与保持架盖是螺纹连接，另一端与另外一个保持架盖是焊接在一起，这种结构的设计，在大型机械和振动激烈的设备中焊接处易开焊、松动、断裂，出现轴承早期异常损坏的现象。
发明内容
本发明的目的在于克服上述技术不足，提供一种支柱两端螺纹直径尺寸不同，螺纹直径大的一端采取螺纹连接加焊接的空心滚子轴承。
本发明解决技术问题所采用的技术方案是：一种空心滚子轴承，包括轴承内圈和轴承外圈，在轴承内圈和轴承外圈之间均匀分布对称的装有多对圆锥滚子，圆锥滚子活动地装在支柱上，支柱外端的螺纹一与保持架小端盖螺纹连接，其特征在于并用焊点将保持架小端盖与支柱固定在一起；支柱内端的螺纹二与保持架大端盖螺纹连接，螺纹一直径Φ1大于螺纹二直径Φ2，其值为1mm～20mm。
本发明的有益效果是：该发明避免了焊接处易开焊、松动、断裂，出现轴承早期异常损坏的现象，提高了使用寿命，方便安装，承载抗震能力强。
附图说明
以下结合附图，以实施例具体说明：
图1是空心滚子轴承实施例一滚子为圆锥的主视图；
图2是空心滚子轴承实施例二滚子为圆柱的主视图。
图中：1-轴承内圈；2-螺纹一；3-焊点；4-支柱；5-保持架小端盖；6-圆锥滚子；7-轴承外圈；8-保持架大端盖；9-螺纹二；10-轴孔；11-保持架端盖二；12-圆柱滚子；13-保持架端盖一；Φ1-螺纹一直径；Φ2-螺纹二直径。
具体实施方式
实施例一，参照附图1，一种空心滚子轴承，包括轴承内圈1和轴承外圈7，在轴承内圈1和轴承外圈7之间均匀分布对称的装有多对圆锥滚子6，圆锥滚子6活动地装在支柱4上，支柱4外端的螺纹一2与保持架小端盖5螺纹连接，其特征在于并用焊点3将保持架小端盖5与支柱4固定在一起；支柱4内端的螺纹二9与保持架大端盖8螺纹连接，螺纹一直径Φ1大于螺纹二直径Φ2，其值为1mm~20mm。
轴承内圈1中心设有轴孔10，用于与设备中的轴连接。
安装时，将支柱4螺纹二直径Φ2从螺纹一直径Φ1中插入，安好螺纹后将保持架小端盖5与支柱4通过焊点3焊接在一起。
实施例二，参照附图2，主要技术特征完全同实施例一，只是轴承内圈1、轴承外圈7形状有点区别；支柱4上只装一个圆柱滚子12，保持架端盖二11相当于实施例一中的保持架小端盖5，保持架端盖一13相当于实施例一中的保持架大端盖8；其它结构特点是一样的。
安装时将支柱4螺纹二直径Φ2从螺纹一直径Φ1中插入，拧好螺纹后，将保持架端盖二11与支柱4通过焊点3焊接在一起。
