In, the nut of the trip bolt is contacted with the bottom hole of locking hole, and dish-type locking member, the lock are both provided with the locking hole
The outer circumferential surface of tight part has external screw thread, and the inner ring wall of the locking hole has the internal thread to match with the external screw thread, described
In the internal thread for screwing into locking hole of locking member, the locking member is against on the nut of trip bolt, the locking hole
Spring is inside both provided with, one end of the spring is against the bottom hole of locking hole, and the other end is against on locking member.
Screw rod in this programme first by trip bolt passes through the jack of magnetic pole body, then by the screw rod of trip bolt
It is tightened on stator case, the nut of trip bolt is against the bottom hole of locking hole, realize and magnetic pole is fixed on stator case,
Then spring is placed in locking hole, screw locking member make its tight against on the nut of trip bolt, effectively prevent because
The loosening of trip bolt caused by vibration, while spring is compressed between locking member and the bottom hole of locking hole, utilizes spring
Elastic force the frictional force between the external screw thread of locking member and the internal thread of locking hole is become larger, it is ensured that locking member will not be because shaking
Move and loosen.
Due to the presence of foozle, easily cause magnetic pole meeting there are gap between the screw rod and locking hole of trip bolt
Tightened relative screw shifts, and further, is respectively and fixedly provided with resilient sleeve in the jack, the resilient sleeve be located at jack with
Between the screw rod of trip bolt, by resilient sleeve tensioner between jack and the screw rod of trip bolt so that magnetic pole and fastening spiral shell
The screw rod of nail is more bonded, and then improves stability of the magnetic pole on stator case.
Preferably, the material of the resilient sleeve is rubber.
Preferably, the material of the magnetic pole body is silicon steel.
The beneficial effects of the utility model are：The locking magnetic pole of the utility model is against on trip bolt by locking member,
So as to preventing the trip bolt on magnetic pole body from loosening, using spring-compressed between the bottom hole of locking hole and locking member it is true
Stability of the magnetic pole on stator case has been protected, has effectively reduced the failure rate of motor.
