一种可快速更换轴承的汽车电机
本技术涉及电机
,尤其涉及一种可快速更换轴承的汽车电机。
技术介绍
目前,新能源汽车行业所应用的驱动电机结构中,其类型通常为永磁同步电机。主要的易损部件为轴承,现有结构的绝大部分是前后轴承直接安装在前后盖上,这样的结构对于更换轴承时,需要对整机进行拆开,将转子移出机体才便于更换轴承,过程中会由于永磁电机转子的磁性问题而对转子防护要求较高,使更换轴承的成本相对较高。据专利文献报导,专利公开号为CN203722387U的“一种能快速更换轴承的电机”,公布了一种能快速更换轴承的结构,该结构是由是包括机壳、定子、转子、前端盖、前轴承座、前轴承外压板、前轴承、前轴承内压板、锁紧圆螺母、后轴承、挡圈、后轴承内压板、轴、密封圈、后轴承座和后端盖组成,所述结构主要特点为前后轴承座与前后盖的结合为圆柱面结合。这种结构虽然也能使轴承进行快速简单的更换,但是其运行精度比较差,对定子和转子之间的气息波动比较大,轴承长时间处于不同轴的工作环境,寿命降低。据专利文献报导,专利公开号为CN207039350U的“轴承易拆式电机”,公布了一种轴承易拆式电机的结构,该结构是由转子,定子,转轴,前轴承,后轴承,前护盖,后护盖,前端盖和后端盖构成。所述结构前端盖和后端盖都有缺口槽,结构相对复杂,加工制造耗时耗力。
