Abstract

The utility model discloses an axial displacement detector, which is used for monitoring the axial end play of a rotary spindle of a medium or small rotary machine. The axial displacement detector is arranged on the non-motor-coupled end of the rotary spindle, moreover, the rotary spindle is connected with a guide wing through a servo bearing, the guide wing is connected with a connecting rod, the connecting rod is connected with a pointer through a servo pin, and the pointer is mounted on a dial. Two wing plates are symmetrically arranged on the outer diameter of the guide wing, two guide grooves are arranged on both sides in a spindle end cover positioned on the non-motor-coupled end of the rotary spindle, and the two wing plates are correspondingly arranged in the two guide grooves. The axial displacement detector does not need the support of electricity, and can meet the requirements of an explosion-proof environment in particular; the structure is simple, and the axial displacement detector is easy to implement, and can safely and reliably operate.

Description

The axial displacement detecting device

Technical field

The utility model relates to a kind of axial displacement detecting device that is used to monitor middle-size and small-size rotating machinery main shaft axial motion displacement.

Background technology

At present, middle-size and small-size rotating machinery main shaft axial motion displacement generally is to judge by operational management personnel's working experience, tends to occur failing to judge or misjudging, and brings hidden danger for like this safety in production of middle-size and small-size rotating machinery; And since the main shaft string moving must be that its internal part has wearing and tearing, need change maintenance to it, inner but it is contained in machinery, be difficult to observe directly its frayed situation, observe if regularly shut down dismounting machinery, also uneconomical, influence the production of enterprise simultaneously.

Summary of the invention

Technical problem to be solved in the utility model is, at the prior art deficiency, provides a kind of and need not electric weight, can satisfy anti-riot environment needs, rotary main shaft axial displacement detecting device simple in structure, easy to implement, safe and reliable to operation.

For solving the problems of the technologies described above; the technical scheme that the utility model is protected is: a kind of axial displacement detecting device; be used to monitor the axial string momentum of the rotary main shaft of middle-size and small-size rotating machinery; it is arranged at the non-motor shaft coupling end of this rotary main shaft; and this rotary main shaft connects guide vane by the servo-actuated bearing; this guide vane connects a connecting rod, and this connecting rod is by the follower peg concatenation pointer, and this pointer is assemblied on the dial plate.

Be symmetrical arranged two wing plates on the external diameter of this guide vane, the axle head outer cover symmetria bilateralis that is positioned at the non-motor shaft coupling of rotary main shaft end is provided with two gathering sills, and two wing plate correspondences place two gathering sills.

The outside of this guide vane is sequentially with locking plate and setscrew nut.

This connecting rod is connected in the intermediate point of the guide vane between two wing plates.

Compared with prior art, the beneficial effect that the utility model had is: 1, the practicality of the utility model utilization mechanical linkage drive mechanism the monitoring of rotary main shaft axial string momentum, not only do not have the electric weight demand, less demanding to working environment; And simple in structure, reliable operation, easy to implement, at the bottom of the manufacturing cost, be easy to promote.2, the utility model carries out the ratio amplification by pointer with small axial displacement, is convenient to observation.

Embodiment

As shown in Figure 1 and Figure 2, the utility model axial displacement detecting device is arranged at the non-motor shaft coupling end of a rotary main shaft 12, and this rotary main shaft 12 connects guide vane 11 by servo-actuated bearing 10, the outside of this guide vane 11 also is sequentially with locking plate 8 and setscrew nut 9, and servo-actuated bearing 10 and guide vane 11 and the relative position of rotary main shaft 12 are fixed.One side of this guide vane 11 connects a connecting rod 3 by register pin 2, and this connecting rod 3 is by follower peg 7 concatenation pointers 6, and this pointer 6 is assemblied on the dial plate 1.When rotary main shaft 12 rotations, under the effect of servo-actuated bearing 10, guide vane 11 does not rotate with rotary main shaft, only when axial motion appears in rotary main shaft 12, guide vane 11 just moves axially with servo-actuated bearing 10, and drive the connecting rod 3 be attached thereto, connecting rod 3 drives pointer 6 again and does the rotation pendular motion around pointer pin 5 in the certain angle scope, thereby the small axial string momentum of rotary main shaft 12 is enlarged into the angular displacement that pointer 6 is swung by the linkage assembly of being made up of connecting rod 3 and pointer 6, equipment management personnel can be detected by an unaided eye.For this guide vane 11 is only moved axially, also be symmetrical arranged two wing plates 111 on the external diameter of this guide vane 11, axle head outer cover 4 both sides that are positioned at rotary main shaft 12 non-motor shaft coupling ends also are symmetrical arranged two gathering sills, 41, two wing plates, 111 correspondences and place two gathering sills 41.For the staff being convenient to observe the state of pointer 6, connecting rod 3 can be connected in the intermediate point of the guide vane 11 between two wing plates 111.
