Abstract

The utility model discloses a shock-proof structure of an encoder, which is mounted between the encoder and a motor support. The shock-proof structure is characterized in that the shock-proof structure comprises a shock-proof ring elastic sheet and a shock-proof ring housing, wherein the shock-proof ring elastic sheet is a four-claw elastic sheet; four extended ends of the four-claw elastic sheet extend from the center and are uniformly distributed at the circumference; the tail ends of the four extended ends are fixedly mounted at the inner edge of the shock-proof ring housing by screws; and encoder fixing holes that are fixed with the encoder are formed in the shock-proof ring elastic sheet. According to the shock-proof structure, as an elastic sheet structure in the shock-proof structure is improved, the shock amplitude can be dispersed by the four extended ends equally; the four extended ends are divided into eight screw fixing positions, and the shock-proof and shock-absorption effects are further improved; in addition, the extended ends of the four-claw elastic sheet are provided with hyperbolic wavy undulations, and the four-claw elastic sheet has a better undulation buffer effect compared with a straight fin in the process of coping with a strong shock; the integral shock-absorption effect of the shock-proof structure keeps good, and the shock is dispersed uniformly; in addition, the good mechanical property of the shock-proof structure is ensured; and the shock-proof structure is not bent and does not deform easily.

Description

The scrambler anti-vibration structure

[technical field]

Scrambler is a kind of senser element that adopts photoelectricity or magnetoelectricity method the mechanical corner of axle to be converted to numeral or the output of analog electrical signal.

[background technology]

Scrambler is a kind of senser element that adopts photoelectricity or magnetoelectricity method the mechanical corner of axle to be converted to numeral or the output of analog electrical signal.The equipment of the signal form that can be used for communication, transmission and storage worked out signal or mechanical motion position, be converted to by scrambler.Scrambler angular displacement or the suspicion displacement convert electric signal to.Scrambler is mainly used on the industry control industry, is installed in the motor back, plays the signal feedback effect, is the information hub between motor and the driver.Displacement signal above the motor is converted into afterwards transmission of electric signal to be fed back on the main control terminal.

Original scrambler anti-vibration structure is arranged on the bearing on scrambler and the motor, spring leaf by a strip is installed in above the scrambler, then be installed on the motor support base by two screws at two ends with the scrambler axes alignment, owing to only aim at by two screw location, so centering adjustment poor-performing, and two ends location structure, all shaking force is born decomposition by two ends, each end has all born very big bang dynamics, can not effectively shift and disperse, cause the shock-absorbing poor performance, even pressure distortion or phenomenon of rupture can occur.

[summary of the invention]

The utility model for above problem proposed especially that shock-proof effect is good, centering adjustment is easy to the scrambler anti-vibration structure.

The technical solution of the utility model is: a kind of scrambler anti-vibration structure, be installed between scrambler and the motor support base, it is characterized in that, comprise shock-absorbing circle shell fragment and shock-absorbing circle shell, described shock-absorbing circle shell fragment is a four paws shell fragment that extends four circumference uniform distribution elongation ends from the center, and the tail end of described four elongation ends is screwed and is installed to the interior along upper of shock-absorbing circle shell; On described shock-absorbing circle shell fragment, also have the scrambler fixed orifice fixing with scrambler; Described four elongation end tail ends have one to the stiff end of axial direction turnover, and described stiff end has the screw fixed bit that shock-absorbing circle shell fragment is fixed to shock-absorbing circle shell.

Described stiff end have with shock-absorbing circle shell in along the radian that fits, and respectively be distributed with two screw fixed bits as the symcenter both sides take elongation end.

Described four elongation ends are to have the contoured gusset of hyperbolic curve wave along the vibrations direction.

Described scrambler fixed orifice has four, and each scrambler fixed orifice is mingled with and is distributed between two elongation ends.

The beneficial effects of the utility model: this scrambler anti-vibration structure is by the elastic piece structure in the improvement anti-vibration structure, four elongated ends are the dissipate shock amplitude on average, and being separated into eight screw fixed bits, four elongated ends further promote the shock-absorbing damping effect, the elongation end of four paws shell fragment also has the fluctuating of hyperbolic curve wave shape simultaneously, than straight muscle sheet the fluctuating buffering effect when shaking, the reply brute force is arranged more, maintenance anti-vibration structure integral shock-absorbing is respond well, dissipate shock is even, guarantee simultaneously the good mechanical properties of anti-vibration structure, be difficult for flexural deformation.

[embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.

The anti-vibration structure of between scrambler and motor support base, installing, need shock-proof effect good, mechanical property is good, keep its mechanical property in the time of effective shock-absorbing, original shell fragment is difficult to aim at the scrambler center, be difficult to the adjustment center during installation, and could use after needing when mounted the bearing behind the motor reequiped, have and can only rely on two screws to be fixed, concentricity is poor, and whole vibrations dynamics all relies on two gussets and goes conduction vibrations, need to bear very large vibrations dynamics, causes reaching easily fatigue limit and deformation failure, damage physical construction and collapse.

For this phenomenon a kind of new scrambler anti-vibration structure is proposed, be mounted in equally between scrambler and the motor support base, it is characterized in that, comprise shock-absorbing circle shell fragment 1 and shock-absorbing circle shell 2, described shock-absorbing circle shell fragment 1 is a four paws shell fragment that extends four circumference uniform distribution elongation ends 3 from the center, and the tail end of described four elongation ends 3 is screwed and is installed to the interior along upper of shock-absorbing circle shell 2; On described shock-absorbing circle shell fragment 1, also has the scrambler fixed orifice 6 of fixing with scrambler 7; Described four elongation end 3 tail ends have one to the stiff end 4 of axial direction turnover, described stiff end 4 has the radian that fits with shock-absorbing circle shell 2 interior edges, and respectively being distributed with two screw fixed bits 5 as the symcenter both sides take elongation end 3, described screw fixed bit 5 is that shock-absorbing circle shell fragment 1 is fixed to fixed bit on the shock-absorbing circle shell 2.

Described scrambler fixed orifice 6 has four, and each scrambler fixed orifice is mingled with and is distributed between two elongation ends 3.Scrambler fixed orifice 6 is spaced apart with elongation end 3, is conducive to the vibration distribution buffering.

Described four elongation ends 3 are to have the contoured gusset of hyperbolic curve wave along the vibrations direction.Compared with straight gusset, have gusset that the hyperbolic curve wave rises and falls can fluctuate bradyseism, damping, dredge dissipate shock and impact.
