Description
Technical field
The invention belongs to aircraft engine control system power control platform field, relate in particular to a kind of positive and negative push rod mutual interlocking gear.
Background technology
Existing aircraft engine control system power control platform product when carrying out single engine oil door operation, adopts the single swinging boom mode usually, and namely body of rod rotates corresponding the output of one tunnel mechanical/electrical signal.
The power control platform of transport plane (passenger plane) requires to adopt positive and negative push rod (two bar) mode respectively positive thrust, the reaction thrust of driving engine to be controlled.In order to guarantee flight safety, prevent maloperation, should guarantee that in the positive thrust opereating specification, anti-push rod can't operate; After anti-push rod operation, positive push rod can't operate.This just requires to arrange rotating interlocking device in mechanism.This class device has no report at present.
Summary of the invention
A kind of simple operation that the object of the invention is to overcome above-mentioned shortcoming and provide, reliable operation, rotation mutual interlocking gear simple in structure.
Purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Rotation mutual interlocking gear of the present invention comprises positive push rod, push rod, guide, spring, locating dowel pin, anti-push rod and postioning abutment.Wherein: anti-push rod is fixed on the positive push rod by rivet, and anti-push rod is provided with cam, and bar bears down on one on the cam top; Guide is fixed on the positive push rod by rivet, and Compress Spring is loaded in the guide, and push rod passes guide and Compress Spring, and locating dowel pin is fixed in the hole of push rod bottom (can move with push rod).Push rod can slide up and down in guide and Compress Spring; Postioning abutment has the groove that is made of circular arc dead slot and straight trough, and locating dowel pin is positioned at the groove of postioning abutment.
Upper coarse and lower fine formation one step of the body of rod of push rod, Compress Spring are positioned at the following thin shank portion of step.Push rod can slide up and down in guide.
The present invention compared with prior art, as can be known from the above technical solutions, the design of locating dowel pin and postioning abutment so that positive push rod be can sway the time, anti-push rod can't rotate; When anti-push rod can rotate, positive push rod can't rotate.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of invention;
Fig. 2 is positive push rod lock-out state structural representation of the present invention;
Fig. 3 is anti-push rod lock-out state structural representation of the present invention;
Mark among the figure:
1, positive push rod; 2, push rod; 3, guide; 4, spring; 5, locating dowel pin; 6, anti-push rod; 7, postioning abutment.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof that the positive and negative push rod that foundation the present invention is proposed rotates mutual interlocking gear are described in detail as follows.
Referring to Fig. 1, the rotation mutual interlocking gear comprises positive push rod 1, push rod 2, guide 3, spring 4, locating dowel pin 5, anti-push rod 6 and postioning abutment 7.Wherein: anti-push rod 6 is fixed on the positive push rod 1 by rivet, and anti-push rod 6 is provided with cam, and bar 2 bears down on one on the cam top; Guide 3 is fixed on the positive push rod 1 by rivet, and Compress Spring 4 is loaded in the guide 3, and push rod 2 passes guide 3 and Compress Spring 4, and locating dowel pin 5 is fixed in the hole of push rod 2 bottoms (can with push rod 2 motions).Push rod 2 can slide up and down in guide 3 and Compress Spring 4; Postioning abutment 7 has the groove that is made of circular arc dead slot and straight trough, and locating dowel pin 5 is positioned at the groove of postioning abutment 7.
Upper coarse and lower fine formation one step of the body of rod of push rod 2, Compress Spring 4 are positioned at the following thin shank portion of step.Push rod 2 can slide up and down in guide 3.
During use, postioning abutment 7 maintains static, and is used for the motion of restriction locating dowel pin 5.
Referring to Fig. 1, when positive push rod 1 when moving clockwise, locating dowel pin 5 moves in postioning abutment 7 circular arc dead slots, anti-push rod 6 moves to anticlockwise direction; After rotating anti-push rod 6, the cam on the anti-push rod 6 pushes up the bar 2 that bears down on one, and Compress Spring 4, locating dowel pin 5 up-and-down movement in postioning abutment 7 straight troughs of fixing on the push rod 2.
Referring to Fig. 2, anti-push rod 6 is pulled up, and the cam on the anti-push rod 6 pushes up the bar 2 that bears down on one and moves downward, and locating dowel pin 5 fixing on the push rod 2 is stuck in postioning abutment 7 straight troughs.At this moment, positive push rod 1 can not rotate.
Referring to Fig. 3, when positive push rod 1 is crossed position shown in Figure 1, at this moment, when rotating counterclockwise anti-push rod 6, fixing locating dowel pin 5 can't move downward above in postioning abutment 7 ring shaped slots on the push rod 2, therefore anti-push rod 6 can't rotate.
