Abstract
The utility model discloses a transmission shaft speed detector, the slide mechanism comprises a spindle sleeve, the axle sleeve is equipped with the bearing overcoat outward, be equipped with the bearing between bearing overcoat and axle sleeve, bolt fixedly connected with locating piece is passed through on bearing overcoat left side top, bearing overcoat right side is fixed with proximity switch through the proximity switch fixed block, the axle sleeve bottom is equipped with the tachometer disc. The utility model discloses when the rotation of axes, the axle sleeve is fixed at epaxial synchronous revolution, and the bearing overcoat keeps static relatively owing to there is the locating piece fixed, through the relative motion of proximity switch and tachometer disc, obtains continuous tachometer signal, can convert into the rotational speed, and tachometer disc and proximity switch integrative structure with chenging, can improve tachometer disc and proximity switch relative position's accuracy, assurance signal acquisition's accuracy and steadily.
Description
Technical field
This utility model is related to rotating speed of transmission shaft field of measuring technique, specially a kind of rotating speed of transmission shaft detection means.
Background technology
Power transmission shaft generally requires the rotating speed of power transmission shaft is measured in use, is easy to the research to power transmission shaft.Often
Can be measured using the cooperation of proximity switch and tachometer disc.Traditional speed measuring device proximity switch and tachometer disc are partial installations
, not only higher to the installation requirement of proximity switch, and in long-play, due to the vibrations of power transmission shaft and close
The shake of switch mounting bracket, can cause the distance between proximity switch and tachometer disc to change, lead to dropout, finally
The rotating speed obtaining is forbidden.
Utility model content
The purpose of this utility model is to provide a kind of rotating speed of transmission shaft detection means, to solve to carry in above-mentioned background technology
The problem going out.
For achieving the above object, this utility model provides following technical scheme：A kind of rotating speed of transmission shaft detection means, including
Axle sleeve, described axle sleeve is externally provided with bearing outside, and described bearing outside and shaft room are provided with bearing, top on the left of described bearing outside
It has been bolted to connection locating piece, on the right side of described bearing outside, proximity switch has been fixed with by proximity switch fixed block, institute
State axle sleeve bottom and be provided with tachometer disc.
Preferably, described bearing top and axle sleeve contact position are provided with the shaft block ring for fixing bearing.
Preferably, described bearing and bearing outside contact position are provided with the hole back-up ring for fixing bearing.
Preferably, described bearing is oiliness bearing.
Compared with prior art, the beneficial effects of the utility model are：When the shaft is rotated, axle sleeve is fixed on this utility model
Synchronous rotary on axle, bearing outside, due to there being locating piece to fix, keeps geo-stationary, relative with tachometer disc by proximity switch
Motion, obtains continuous tachometer signal, you can be converted into rotating speed, tachometer disc and proximity switch all-in-one-piece structure, can improve
The accuracy of tachometer disc and proximity switch relative position it is ensured that signals collecting accurately and stable.
Brief description
Fig. 1 is this utility model structural representation.
In figure：1 axle sleeve, 2 bearings, 3 bolts, 4 locating pieces, 5 hole back-up rings, 6 tachometer discs, 7 shaft block rings, 8 proximity switches

The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme：A kind of rotating speed of transmission shaft detection means, including axle sleeve
1, it is cased with bearing outside 10 outside described axle sleeve 1, between described bearing outside 10 and axle sleeve 1, is provided with bearing 2, described bearing outside 10 is left
Side top is fixedly connected with locating piece 4 by bolt 3, and described bearing outside 10 right side is fixed with by proximity switch fixed block 8
Proximity switch 9, described axle sleeve 1 bottom is provided with tachometer disc 6.
Described bearing 2 top and axle sleeve 1 contact position are provided with the shaft block ring 7 for fixing bearing 2.Described bearing 2 and axle
Hold overcoat 10 contact position and be provided with the hole back-up ring 5 for fixing bearing 2.Described bearing 2 is oiliness bearing.
Specifically, during use, when the shaft is rotated, axle sleeve 1 is fixed on synchronous rotary on axle, bearing outside 10 to this utility model
Due to there being locating piece 4 fixing, keep geo-stationary, by the relative motion of proximity switch 9 and tachometer disc 6, continuously surveyed
Fast signal, you can be converted into rotating speed, tachometer disc 6 and proximity switch 9 all-in-one-piece structure, can improve tachometer disc 6 and close to opening
Close the accuracy of 9 relative positions it is ensured that signals collecting accurately and stable.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
