Abstract
The invention relates to a special-shaped shaft of a motor encoder. The special-shaped shaft comprises a thread connecting part, an encoder fixing part and a motor fixing part, wherein the thread connecting part comprises external threads, the encoder fixing part comprises an encoder shaft sleeve fixing section and a special-shaped circular truncated cone close to the motor fixing part, the special-shaped circular truncated cone comprises three U-shaped holes which are uniformly distributed, and the motor fixing part comprises three circular holes which are uniformly distributed. The special-shaped shaft has the beneficial effects that the structure form of an original special-shaped shaft of the encoder is mainly changed, and is mainly reflected as follows: (1) the special-shaped circular truncated cone is additionally arranged; and (2) a clamping fastener consisting of a gasket and an elastic washer is used in a transitional section, so that the encoder loosens due to long-term use can be effectively avoided. The special-shaped shaft has the advantages of simple structure, low cost and good using effect.
Description
Technical field
The present invention relates to mechanical mounting technique field, especially relate to a kind of special-shaped axis that large shaft sleeve type encoder is installed that is applicable to.
Background technique
At present, the mode of installing and fixing of the large shaft sleeve type encoder that known motor or mechanical device adopt is: the encoder axle sleeve is fixed on the d-axis that motor or mechanical device draw with screw, adopts spring sheet that the encoder body is fixed on motor or the basic machine.When motor or mechanical ejector rotated, the d-axis of motor or mechanical ejector rotated, and drove the encoder axle sleeve and rotate, and reached functional requirement such as test the speed thereby the encoder body is static.But, the big or impingement load for vibration, this means of fixation is also insecure, and it is loosening to occur encoder axle sleeve retaining screw easily, thus causing encoder to detect lost efficacy, the drive unit false judgment causes accident to take place.
Summary of the invention
The objective of the invention is to overcome that the encoder axle sleeve that exists in the prior art is vibrated and the encoder that causes detects malfunctioning shortcoming, a kind of axle sleeve type motor encoder special-shaped axis is provided, use the fixing encoder of this special-shaped axis, preferably resolve the fixing loosening problem of the encoder axle sleeve that causes under the impact shock situation, the technological scheme that adopts is: a kind of motor encoder special-shaped axis, it is characterized in that: described special-shaped axis comprises the part that is threaded, encoder standing part and motor standing part, described threaded joints branch comprises outside thread, described encoder standing part comprises the special-shaped round platform of encoder axle sleeve holding part and close described motor standing part, comprise three uniform U-shaped holes on the described special-shaped round platform, described motor standing part comprises three uniform circular holes.
Technical characteristics of the present invention also has: described special-shaped round platform radius is 40mm, and described encoder axle sleeve holding part radius is 30mm.
Technical characteristics of the present invention also has: described axle sleeve type motor encoder special-shaped axis also comprises the changeover portion that is threaded between part and the encoder standing part described, and the radius of described changeover portion is less than the described part radius that is threaded.
Beneficial effect of the present invention is: the present invention has changed the structural type of original encoding device special-shaped axis, mainly shows as: 1) set up special-shaped round platform; 2) clamp fixer that has used pad and elastic washer to form at changeover portion like this, can effectively avoid encoder to use loosening that the back produces for a long time, the advantage that the present invention has is simple in structure, with low cost, using effect is good.
Description of drawings
Accompanying drawing 1 is plan view of the present invention, and accompanying drawing 2 is right elevations of accompanying drawing 1, and accompanying drawing 3 is A-A views of accompanying drawing 1, accompanying drawing 4 is that the present invention uses view, and wherein I is the part that is threaded, and II is the encoder standing part, III is the motor standing part, IV is changeover portion, the 1st, and special-shaped round platform, the 2nd, U-shaped hole, the 3rd, circular hole, the 4th, set screw nut, the 5th, pad, the 6th, elastic washer.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of axle sleeve type motor encoder special-shaped axis, this kind special-shaped axis is used for fixed axle sleeve type motor encoder, this special-shaped axis comprises the part I that is threaded, encoder standing part II, motor standing part III and in the changeover portion IV that is threaded between part I and the encoder standing part II, the radius of changeover portion IV is less than the radius of the part I that is threaded.
The part that is threaded I comprises outside thread, encoder standing part II comprises the special-shaped round platform 1 of encoder axle sleeve holding part and close motor standing part III, abnormity comprises three uniform U-shaped holes 2 on the round platform 1, so-called uniform refer to three U-shaped holes 2 between any two angle be 120
o, motor standing part III comprises three uniform circular holes 3.
In the present embodiment, special-shaped round platform 1 radius is 40mm, and encoder axle sleeve holding part radius is 30mm.
During use, the encoder axle sleeve is contained on the encoder axle sleeve holding part, its left side pushes against special-shaped round platform 1, and its right side is adorned pad 5, elastic washer 6 and set screw nut 4 successively, and the encoder axle sleeve is still fixed with retaining screw.After this method installation, when motor rotates, whole special-shaped axis and encoder axle sleeve are along with motor rotates, after vibration caused the retaining screw of encoder axle sleeve to become flexible more greatly, the encoder axle sleeve still can keep firmly by the effect of special-shaped round platform 1, pad 5, elastic washer 6 and set screw nut.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also belong to protection scope of the present invention.
Claims (3)
