Abstract

本实用新型公开了一种三球销万向节。它包括三销架，在三销架上设有三个可装配三个无保持架通孔滚针轴承的椭圆轴颈，滚针轴承具有滚针、球环，并利用滚针挡圈、钢丝挡圈将三销架和滚针轴承限位，其特征在于在三销架上与滚针轴承相接处设有台肩。本实用新型为了使各零件同等寿命，取消滚针垫片，在三销架轴颈台肩上增设台肩替代滚针垫片，由于三销架台肩表面硬度为HRC58～62，渗碳层为0.7～1.0mm，从而保证台肩端面的耐磨损性能，提高三销架寿命。

Description

三球销万向节
                         技术领域
本实用新型涉及一种三球销万向节。
                         背景技术
三球销万向节作为可轴向移动三球销万向节的一个关键零件，与轴连接，摆角时产生滑移，它由三销架、滚针、滚针垫片、滚针挡圈、钢丝挡圈、球环组成。在使用过程中，滚针头部不断接触滚针垫片，由于滚针硬度为HRC61～65，滚针垫片厚度较薄，硬度为HRC45～50，又由于接触硬度不匹配，导致滚针垫片的磨损加快，使各零件达不到同等寿命。
                        发明内容
本实用新型的目的是提供一种三球销万向节。
它包括三销架，在三销架上设有三个可装配三个无保持架通孔滚针轴承的椭圆轴颈，滚针轴承具有滚针、球环，并利用滚针挡圈、钢丝挡圈将三销架和滚针轴承限位，其特征在于在三销架上与滚针轴承相接处设有台肩。
本实用新型为了使各零件同等寿命，取消滚针垫片，在三销架轴颈台肩上增设台肩替代滚针垫片，由于三销架台肩表面硬度为HRC58～62，渗碳层为0.7～1.0mm，从而保证台肩端面的耐磨损性能，提高三销架寿命。
                        附图说明
附图是三球销万向节结构示意图。
                       具体实施方式
三球销万向节包括三销架1，在三销架上设有三个可装配三个无保持架通孔滚针轴承的椭圆轴颈，滚针轴承具有滚针2、球环3，并利用滚针挡圈4、钢丝挡圈5将三销架和滚针轴承限位，其特征在于在三销架上与滚针轴承相接处设有台肩6。
