Reduce friction.
Preferably, the chamfering is symmetricly set on the locking nut, good appearance, prevents from damaging.
Preferably, the spring and hand turning handle strut the inner ring of conical bore self-aligning bearing, without beaing conical bore aligning
Bearing installs conical bore self-aligning bearing, protects the overall performance of conical bore self-aligning bearing, while has been also convenient for installation, effectively
Control installation site.
Preferably, the both ends of the conical bore self-aligning bearing are separately positioned on the both ends of installation portion, and locking nut is in screw thread
Being rotated in portion can promote conical bore self-aligning bearing to push against onto installation portion, easy for installation.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the both ends that can make conical bore self-aligning bearing by the installation portion of setting protrude, and locking nut rotates on threaded portion
Conical bore self-aligning bearing can be promoted to push against easy installation and removal on installation portion.
When the 2nd, sleeve can be reduced by the spring and cylinder axis of setting being moved between conical bore self-aligning bearing and rotating shaft
Resistance, conical bore self-aligning bearing is easily installed, is more convenient, be more laborsaving, and shorten the set-up time, and make tightening
Set is effectively protected, no damage, is also beneficial to dismounting, can be used for multiple times.
3rd, the installation of conical bore self-aligning bearing can be facilitated by the locking nut of setting, reduces the difficulty of processing of rotating shaft,
Easy for installation, the conical surface of locking nut and working good for conical bore self-aligning bearing are simple to operate.
