In　this　paper,　for　double　row　angular　contact　ball　bearing,　a　five-degrees-of-freedom　bearing　analysis　model　based　on　quasi-statics　is　proposed.　This　model　is　used　to　study　the　influence　of　structural　parameters　and　service　conditions　on　the　tilt　angle　and　limit　tilt　angle　of　the　bearing.　The　results　show　that　the　radial　clearance　will　increase　the　ultimate　tilt　angle.　The　coincidence　degree　between　the　roller　and　the　inner　raceway　will　reduce　the　ultimate　tilt　angle,　but　the　coincidence　degree　between　the　roller　and　the　outer　raceway　has　the　opposite　effect.　The　increase　in　the　external　load　of　the　bearing　will　increase　the　tilt　angle.　The　moment　load　has　the　greatest　effect　on　the　tilt　angle.　The　rotation　speed　of　the　bearing　has　no　effect　on　the　tilt　angle.　The　coincidence　degree　between　the　roller　and　the　raceway　will　reduce　the　tilt　angle;　furthermore,　the　influence　of　the　coincidence　degree　between　roller　and　different　ring　on　the　tilt　angle　is　also　different　when　different　rings　are　fixed.　The　tilt　angle　will　decrease　with　the　increase　of　the　initial　contact　angle,　and　this　effect　is　more　and　more　obvious.　The　fixation　of　different　ring　has　no　effect　on　this　influence.　©　IMechE　2021.
