Abstract
The utility model relates to a kind of linear movement pick-up miniaturization swivel link shelf structure.The technological scheme that the utility model is taked is, a kind of linear movement pick-up miniaturization swivel link shelf structure: comprise outer nut 1, inner nut 2, bearing 3, connecting rod rest 4, link assembly 5.Described connecting rod rest structure, outer nut 1 and connecting rod rest 4 are threaded connection, push down the outer ring, both sides of two bearings 3 respectively, inner nut 2 and link assembly 5 are threaded connection, push down the both sides inner ring of two bearings 3 respectively, form rotational structure, this rotational structure reduces the volume of sensor connecting rod rest structure diametrically greatly.Make it to become possibility for small-sized rotatable connecting rod rest linear movement pick-up.
Description
Technical field
The present invention relates to a kind of radial miniaturization swivel link shelf structure.
Background technique
Redundancy linear movement pick-up has a great development in connecting rod rest configuration aspects, due to the impact of its high oil pressure of aeroengine, and the needs of assembly system, the rotatable connecting rod rest structural type of the current redundancy linear movement pick-up many employings of its mover connecting rod rest part, this kind of form can meet connecting rod rest when connecting engine main pump system connecting rod head axially unfettered.On the other hand, because linear movement pick-up causes the problems such as clamping stagnation when machining is connected with main pump system with connecting rod head because machining error may cause connecting rod rest to be subject to certain active force in radial direction, the design of rotatable connecting rod rest effectively can offset the active force of part from radial direction, makes sensor flexible durable more.
But original rotatable connecting rod rest structure is due to design reasons, and bearing chamber design, between redundancy connecting rod rest, can only use in the space that radial direction is greater than bearing chamber.In the face of the demand that aeroengine main pump system will be sought development to sensor miniaturization, exigence designs the structure of the connecting rod rest that can reduce radial dimension.The present invention just can meet the requirement of miniaturization swivel link shelf structure.
Summary of the invention
The purpose of this utility model designs a kind of swivel link shelf structure of radial miniaturization, meets the requirement of aeroengine redundancy linear movement pick-up miniaturization.
The technological scheme that the utility model is taked:
A kind of linear movement pick-up miniaturization swivel link shelf structure, comprise outer nut 1, inner nut 2, bearing 3, connecting rod rest 4, link assembly 5, outer nut 1 and connecting rod rest 4 are threaded connection, and push down the outer ring, both sides of two bearings 3 respectively, and inner nut 2 and link assembly 5 are threaded connection, push down the both sides inner ring of two bearings 3 respectively, form rotational structure.
Bearing chamber is positioned at the top of link assembly 5, and two core assemblies in link assembly 5 are not subject to bearing chamber size constrained in radial direction arrangement.
There is Design of Screw Thread outer nut 1 one end, can be connected with main pump system by screw thread, and inner nut 2 one end can be connected by screw thread with link assembly 5, locking bearing 3 inner ring.
The advantage that the utility model has and beneficial effect: this rotational structure reduces the volume of sensor connecting rod rest structure diametrically greatly, make two core assemblies in link assembly 5 not be subject to the restriction of bearing chamber, two core assemblies can infinite approach.So just can reduce the radial space that sensor occupies, meet the requirement of radial miniaturization, save space.

Embodiment
As shown in Figure 1: a kind of linear movement pick-up miniaturization swivel link shelf structure, comprise outer nut 1, inner nut 2, bearing 3, connecting rod rest 4, link assembly 5, outer nut 1 and connecting rod rest 4 are threaded connection, push down the outer ring, both sides of two bearings 3 respectively, inner nut 2 and link assembly 5 are threaded connection, push down the both sides inner ring of two bearings 3 respectively, locked bearing inner race, rotational structure is formed by bearing ball, this rotational structure reduces the volume of sensor connecting rod rest structure diametrically greatly, make it to become possibility for small-sized rotatable connecting rod rest linear movement pick-up.The design of rotatable connecting rod rest simultaneously effectively can offset the active force of part from radial direction, makes sensor flexible durable more.
Bearing chamber is positioned at the top of link assembly 5, and two core assemblies in link assembly 5 are not subject to bearing chamber size constrained in radial direction arrangement.
There is Design of Screw Thread outer nut 1 one end, can be connected with main pump system by screw thread, and inner nut 2 one end can be connected by screw thread with link assembly 5, locking bearing 3 inner ring.
