Abstract
A kind of motor encoder special-shaped axis, special-shaped axis includes threaded part, encoder standing part and motor standing part, threaded joints divides and includes external screw thread, encoder standing part includes encoder axle sleeve canned paragraph and the special-shaped round platform near motor standing part, including three uniform U-shaped holes on abnormity round platform, motor standing part includes three uniform circular holes.The beneficial effects of the present invention is: the present invention changes the version of original encoding device special-shaped axis, main manifestations is: 1) be additionally arranged abnormity round platform；2) employing pad and the clamp fixer of elastic washer composition at changeover portion, so, what produce after being prevented effectively from encoder life-time service loosens, the advantage that the present invention has simple in construction, with low cost, result of use is good.
Description
Technical field
The present invention relates to mechanical mounting techniques field, especially relate to a kind of special-shaped axis being applicable to install large shaft sleeve type encoder.
Background technology
At present, the installation fixed form of the large shaft sleeve type encoder that known motor or machinery adopt is: be screwed by encoder axle sleeve on the d-axis that motor or machinery are drawn, and adopts spring leaf to be fixed on motor or basic machine by encoder body.When motor or machinery ejector rotate, the d-axis of motor or machinery ejector rotates, and drives encoder axle sleeve to rotate, and encoder body is static thus reaching functional requirements such as testing the speed.But, the relatively big or impingement load for vibration, this fixed form is also insecure, it is easy to occur that encoder axle sleeve fixed screw loosens, and causes encoder detection inefficacy, driving device false judgment thus causing that accident occurs.
Summary of the invention
The shortcoming that the encoder detection that it is an object of the invention to overcome the encoder axle sleeve existed in prior art vibrated and to cause is malfunctioning, a kind of axle sleeve type motor encoder special-shaped axis is provided, use the encoder that this special-shaped axis is fixing, preferably resolve the encoder axle sleeve caused in impact shock situation and fix loosening problem, the technical scheme is that a kind of motor encoder special-shaped axis, it is characterized in that: described special-shaped axis includes threaded part, encoder standing part and motor standing part, described threaded joints divides and includes external screw thread, described encoder standing part includes encoder axle sleeve canned paragraph and the special-shaped round platform near described motor standing part, described abnormity round platform includes three uniform U-shaped holes, described motor standing part includes three uniform circular holes.
The technical characteristic of the present invention also has: described abnormity round platform radius is 40mm, and described encoder axle sleeve canned paragraph radius is 30mm.
The technical characteristic of the present invention also has: described axle sleeve type motor encoder special-shaped axis also includes the changeover portion between described threaded part and encoder standing part, and the radius of described changeover portion is less than described threaded part radius.
The beneficial effects of the present invention is: the present invention changes the version of original encoding device special-shaped axis, main manifestations is: 1) be additionally arranged abnormity round platform；2) employing pad and the clamp fixer of elastic washer composition at changeover portion, so, what produce after being prevented effectively from encoder life-time service loosens, the advantage that the present invention has simple in construction, with low cost, result of use is good.
Accompanying drawing explanation
Accompanying drawing 1 is front view of the present invention, and accompanying drawing 2 is the right view of accompanying drawing 1, and accompanying drawing 3 is the A-A view of accompanying drawing 1, accompanying drawing 4 is that the present invention uses view, and wherein I is threaded part, and II is encoder standing part, III is motor standing part, IV is changeover portion, and 1 is abnormity round platform, and 2 is U-shaped hole, 3 is circular hole, 4 is fixing nut, and 5 is pad, and 6 is elastic washer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is illustrated.The invention discloses a kind of axle sleeve type motor encoder special-shaped axis, this kind of special-shaped axis is for fixed hub type motor encoder, this special-shaped axis includes threaded part I, encoder standing part II, motor standing part III and the changeover portion IV between threaded part I and encoder standing part II, and the radius of changeover portion IV is less than the radius of threaded part I.
Threaded part I includes external screw thread, encoder standing part II includes encoder axle sleeve canned paragraph and the special-shaped round platform 1 near motor standing part III, including three uniform U-shaped holes 2 on abnormity round platform 1, what is called is uniform refers to that three U-shaped hole 2 angles between any two are 120o, motor standing part III includes three uniform circular holes 3.
In the present embodiment, abnormity round platform 1 radius is 40mm, and encoder axle sleeve canned paragraph radius is 30mm.
During use, being contained in by encoder axle sleeve on encoder axle sleeve canned paragraph, push against abnormity round platform 1, fill pad 5, elastic washer 6 and fixing nut 4 on the right side of it successively on the left of it, encoder axle sleeve is still fixed with fixed screw.After this method installation, when electric machine rotation, whole special-shaped axis and encoder axle sleeve are along with electric machine rotation, and after vibration causes that more greatly the fixed screw of encoder axle sleeve loosens, encoder axle sleeve remains to keep firmly by the effect of abnormity round platform 1, pad 5, elastic washer 6 and fixing nut.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the change made in the essential scope of the present invention of those skilled in the art, remodeling, interpolation or replacement, falls within protection scope of the present invention.
Claims (2)
1. a motor encoder abnormal shape axle, it is characterized in that: described special-shaped axle includes threaded part, encoder standing part and motor standing part, described threaded joints divides and includes external screw thread, described encoder standing part includes encoder axle sleeve canned paragraph and the special-shaped round platform near described motor standing part, described abnormity round platform includes three uniform U-shaped holes, described motor standing part includes three uniform circular holes, described motor encoder abnormal shape axle also includes the changeover portion between described threaded part and encoder standing part, described changeover portion includes the pad installed successively, elastic washer and fixing nut, the radius of described changeover portion is less than described threaded part radius.
2. the motor encoder abnormal shape axle described in claim 1, it is characterised in that: described abnormity round platform radius is 40mm, and described encoder axle sleeve canned paragraph radius is 30mm.
