Description

一种双外圈满球轴承
技术领域
本发明涉及一种轴承，尤其是一种满球轴承。
背景技术
满球轴承能使滚动体在轴承滚道中的排列保持固定距离，防止跑珠，避免滚动体之间互相咬磨，同时使滚动体沿圆周均布化，减少轴承间隙在运转中窜动带来的不利影响；当不使用保持架时，为延长轴承寿命或是加强轴承精度可以选择满珠排列。但是满球轴承滚动体的装填一直是个难题，且满球轴承的密封也是一个需要考虑的问题。
发明内容
本发明就是针对上述问题，提供一种易装填、密封好的双外圈满球轴承。本发明采用以下技术方案：
一种双外圈满球轴承，包括内圈、第一外圈和滚珠，所述内圈和第一外圈对应设置有滚道，其特征在于，所述第一外圈由对称设置的两个半外圈组成，所述两个半外圈通过第二外圈夹紧，所述内圈、第一外圈对应位置设有密封槽，并在密封槽内配套设置有橡胶密封圈，在所述橡胶密封圈的外侧，第二外圈与第一外圈之间，卡紧设置有挡圈，所述挡圈的内侧粘结有与橡胶密封圈抵紧配合的第二橡胶圈，所述橡胶密封圈的内侧设有与第一外圈、内圈抵紧接触的密封唇。
本发明的技术特征还在于：所述滚道在内圈和外圈上对应设置，滚道整体的剖面按正八边形设置，所述正八边形外切于滚珠的圆周，所述正八边形的一条最长对角线与两个半外圈的接触面重合。
采用以上技术方案，本发明具有以下优点：
1.本发明设有设有两个半外圈，方便装填滚珠。本发明的挡圈内侧粘结有第二橡胶圈，可以抵紧橡胶密封圈，且可以防止外部灰尘进入。
2.本发明的橡胶密封圈内侧设有与外圈、内圈抵紧接触的密封唇，可以增强密封性。
3.本发明滚道的设置，使得滚珠在滚道上具有对称的角接触点，可以增加轴承的轴向载荷，同时保证径向载荷。
附图说明
图1是本发明的剖视图。
图2是本发明滚道位置的剖视图。
图3是本发明的上半部分放大示意图。
图中标号：1内圈、2第一外圈、21半外圈、3滚珠、4第二外圈、5橡胶密封圈、51/52密封唇、6挡圈、7第二橡胶圈、8正八边形、9正八边形最长的对角线。
具体实施方式
下面结合附图和实施例对本发明作进一步详细的说明：
实施例1：如图1、图2和图3所示，一种双外圈满球轴承，包括内圈1、第一外圈2和滚珠3，所述内圈1和第一外圈2对应设置有滚道。
为了方便装填滚珠，所述第一外圈2由对称设置的两个半外圈21组合而成。所述两个半外圈21通过第二外圈4夹紧。
所述滚道整体的剖面按正八边形8设置，所述正八边形8外切于滚珠3的圆周，所述正八边形8的一条最长对角线9与两个半外圈的接触面重合。
所述内圈1、第一外圈2对应位置设有密封槽，并在密封槽内配套设置有橡胶密封圈5，所述橡胶密封圈5采用丁晴橡胶材质。
在所述橡胶密封圈5的外侧，第二外圈4与第一外圈2之间，卡紧设置有挡圈6，所述挡圈6一般采用金属材质，以增加强度。所述挡圈6的内侧粘结有与橡胶密封圈5抵紧配合的第二橡胶圈7。为了增加密封可靠性，所述橡胶密封圈5的内侧延伸设有分别与第一外圈2、内圈1抵紧接触的密封唇51、52。
本发明方便滚珠填装，且增加了轴承的轴向载荷，轴承密封性也很好。
