Prevent angular contact ball bearing of sequence of sanqu songs within a particular musical mode

(B, ) the utility model relates to a bearing field, concretely relates to prevent angular contact ball bearing of sequence of sanqu songs within a particular musical mode. It is heat dress trap, includes: the inner circle, outer lane, holder, steel ball, the holder is installed between inner circle and outer lane, a plurality of pocket hole has evenly been seted up on the holder, the spherical pocket hole of pocket hole for having the hold depth, this sphere pocket hole forms through the drilling of spherical drill bit, the fore shaft has been seted up on the external diameter of inner circle, the steel ball install spherical pocket downthehole and replace in the fore shaft that circles. This angular contact ball bearing forms the spherical pocket hole that has the hold depth through spherical drill bit on the holder, and with the inner circle external diameter on the fore shaft cooperation for difficult, the steel ball fish tail scheduling problem of trap that assembly trap in -process appears has been avoided to impress easily steel ball and not falling out of the hold depth in spherical pocket hole, heat can the trap a little, need not specially to equip reliable and simple.
