Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of anti-step-out device of permanent-magnet synchronous door machine, packet
It includes permanent magnet synchronous motor 1, block cam structure 2, rotation axis 3, follower lever 4, belt pulley 5, key 6, elastic device 7, idler wheel 8, consolidate
Determine device 9, block cam structure 2 includes block wheel 201, cam 202, block 203, and follower lever 4 includes block bar 401, idler wheel
Bar 402, block head 403, connecting plate 404, belt pulley 5 are connect by key 6 with the shaft of permanent magnet synchronous motor 1, block cam knot
Structure 2 passes through fixed device 9 and connect and be set in the shaft of permanent magnet synchronous motor 1 with the inside of belt pulley 5, and rotation axis 3 is arranged
In in the front end surface of permanent magnet synchronous motor 1, rotation axis 3 penetrate the middle position of follower lever 4 and follower lever 4 with 3 turns of rotation axis
Dynamic connection, one end of elastic device 7 are connect with connecting plate 404, and the other end is fixedly connected with 1 end face of permanent magnet synchronous motor, cam
202 are set to the lower section of block wheel 201, and block 203 is uniformly arranged on block wheel 201, and block head 403 is set to block bar
401 end, connecting plate 404 are set on roller rod 402, and idler wheel 8 is set on the end of roller rod 402；401 He of block bar
Roller rod 402 is on different horizontal planes；It is designed on block wheel 201 and cam 202 and leads to what fixed device 9 was used cooperatively
Hole；The number of block 203 is four.
When the utility model is used, block wheel 201 and cam 202 are fixed on belt pulley 5 with fixed device 9, idler wheel 8 is again
It connect with roller rod 402, under the action of rotation axis 3, so that follower lever 4 had not only been fixed on permanent magnet synchronous motor 1, but also can enclose
