Preferably, described driven position limited gear center is provided with the centre bore that opens up vertically, the two of the centre bore
End is respectively equipped with locating slot, and described magnet is provided with described locating slot.So, magnet be arranged on locating slot in, position compared with
To be solid and reliable.
Preferably, one end of the driven position limited gear is provided with some radially arranged chutes, in described chute
Provided with the blade being slidably matched, the chute is inner to be provided with the elastic component for pulling blade to be moved to driven position limited gear center.This
Sample, when driven position limited gear rotates, blade is displaced outwardly due to centrifugal action, can stir the machine oil stream in the decelerator body body
It is dynamic, play the effect of lubrication assistant and radiating.
Preferably, described shoulder hole is respectively equipped with bearing at the both ends of worm screw, outside the bearing of shoulder hole opening
Close-fitting lining ring is provided between circle and shoulder hole inwall, the opening of described shoulder hole is provided with end cap, described end cap
It is interior to be provided with oil sealing.Lining ring is set between bearing outer ring and shoulder hole inwall, can effectively prevent that high temperature exothermic causes when rotating speed is higher
Bearing act as a travelling agent circle problem.
The beneficial effects of the utility model are：（1）By deceleration and gate limit sensors limit function is coordinated to integrate
Together, integrated level is high so that gate-controlled components are installed and using more convenient；（2）Improve the lubrication and radiating effect of reductor
Fruit, ensure the reliability of running.
