[specific embodiment]
Embodiment:
Fig. 1-Fig. 2 is please referred to, the present embodiment is phase on-line tuning mechanism 100 comprising the fixed conveyor of fixed setting
Gear flange 2 is threadedly engaged the adjustment screw 4 of transmission, is set in fixation by first bearing 7 with fixed conveyor gear flange 2
Interior helical teeth transmission gear 3 on transmission gear flange 2, be set in adjustment screw 4 by second bearing 10 and outer surface with it is interior
The phase adjustment gear 5 of the cooperation transmission of interior helical teeth 31 of helical teeth transmission gear 3, the external peripheral surface of interior helical teeth transmission gear 3 are set
It is equipped with transmission gear structure 32,32 end of transmission gear structure is provided with driving device (not identifying in figure), on phase adjustment gear 5
It is fixedly installed the connecting rod 14 as power output end.
Fixed conveyor gear flange 2 is fixed in a fixed plate 13.One end of adjustment screw 4 is provided with rotation hand wheel 1.It adjusts
The inside interference fit of whole screw rod 4 is provided with a support shaft 15, and one end that support shaft 15 stretches out adjustment screw 14 is set by bearing
It sets in a fixing seat 16.
The outer surface of adjustment screw 4 is provided with screw thread 41, and one end outer surface of fixed conveyor gear flange 2 is provided with outer spiral shell
Line 21 and the end be provided with 41 mate with threaded holes 22 of screw thread, by rotation adjustment screw 4 to realizing the straight of adjustment screw 4
Line movement.
5 end of phase adjustment gear, which extends outwardly, to be provided with support collar (not identifying in figure), solid in the support collar
Surely it is provided with and adjusts gear 6 with the gap of the interior helical teeth 31 of interior helical teeth transmission gear 3 cooperation transmission.Phase adjustment gear 5 and
Helical teeth on gap adjustment gear 6 is bonded transmission with the both sides of interior helical teeth 31 respectively.Phase adjustment gear 5 and gap adjust gear 6
It is fixed together by screw.Connecting rod 14 passes through gap and adjusts gear 6, when in use, by workpiece to be driven and company
Extension bar 14 is fixedly connected with realization and moves synchronously.In existing gear drive, there is certain mistake in the processing of gear certainly
Difference, therefore, when gear engages, gap is also certainly existed between the tooth of engagement, can existed in engaged transmission so certain
Angular error.And the present embodiment adjusts gear 6 by setting gap, and phase adjustment gear 5 and gap adjustment gear 6 are distinguished
It is bonded with two gear sides of interior 31 gear of helical teeth, in turn, the adjustment tooth being made of phase adjustment gear 5 and gap adjustment gear 6
