Abstract
The utility model discloses an involute spline spindle and crank assembly structure for circuit breakers, which comprises a spindle and a crank, and the spindle is connected with the crank through a sleeve. The involute spline spindle and crank assembly structure for circuit breakers is characterized in that: outer involute splines are arranged on the periphery of the spindle and located at the sleeve joint, corresponding inner involute splines are arranged on the wall of the hole of the crank and located at the sleeve joint, and the outer involute splines and the inner involute splines are pressed and connected. The spindle is axially inserted in the crank, and two engaging teeth are respectively removed from the positions where the outer involute splines correspond to the inner involute splines. The involute spline spindle and crank assembly structure for circuit breakers has the advantages that: the structure is simple, the design is ingenious, the gear-machining method can be adopted, manufacturability is good, and the manufacturing precision is high; the strength of the roots of the inner and the outer involute spline teeth is high, stress concentration is low, centering is easy, a spring operating mechanism and an involute spline spindle mechanism are completely integrated, and a vacuum interrupter can obtain ideal driving force and driving speed.
Description
Technical field
The utility model relates to mechanical structure field, specially refers to a kind of circuit breaker gradually bloom key main shaft and connecting lever assembly structure.
Background technique
Splined is made up of internal spline and external splines.Inside and outside spline is multiple tooth part, and the spline on inner periphery is an internal spline, and the spline on outer cylinder surface is an external splines.Obviously, splined is that flat key is connected in the development on the number.Spline is a normal structure.Because structural type and manufacturing process is different, connect with flat key relatively, splined is having plurality of advantages aspect intensity, technology and the use.
Application number is that 92238576 patent application document discloses a kind of spline connector it is to be formed by two external splines axle sleeves 1, two inner splined holes 3, hold-down ring 4, oil hole 5 and enclosing cover 2 combine and assemble; Axle sleeve with external splines; External splines axis direction is a circular arc; External splines length is sleeve length 1/3～1/2, and the length of inner spline groove is 1/2～2/3 of splined hole length, and inner splined hole and adpting flange are one.But this spline linkage structure can not directly apply to circuit breaker.
In sum, to the defective of existing technology, need a kind of circuit breaker gradually bloom key main shaft and connecting lever assembly structure especially, with the problem of mentioning more than solving.
The model utility content
The purpose of the utility model is to provide a kind of circuit breaker gradually bloom key main shaft and connecting lever assembly structure, through adopting special structural design, thereby realizes the purpose of the utility model.
The technical problem that the utility model solved can adopt following technological scheme to realize:
A kind of circuit breaker gradually bloom key main shaft and connecting lever assembly structure; Comprise main shaft and connecting lever; Said main shaft is connected through sleeve with connecting lever, it is characterized in that, the main shaft periphery face that is positioned at the sleeve joint is provided with the outer key of gradually blooming; The inner hole wall that is positioned at the connecting lever of sleeve joint is provided with the corresponding key of gradually blooming, said outer gradually bloom key and interior gradually bloom key compressing and butt joint.
In an embodiment of the utility model, said main shaft adopts axial INSERTTYPE to be connected with connecting lever, and the corresponding part of outside said, gradually bloom key and the interior key of gradually blooming is removed a tooth engaged respectively.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and can adopt gear working method, good manufacturability, accuracy of manufacturing is high; The root of inside and outside involute splines tooth is high, and stress is concentrated little, is easy to centering, and spring operating mechanism and involute splines mainshaft mechanism are combined together fully, makes vacuum interrupter obtain desirable driving force and transmission speed.
Description of drawings
Fig. 1 is the described a kind of circuit breaker of the utility model gradually bloom key main shaft and connecting lever assembly structure structural representation.
Fig. 2 is the described a kind of circuit breaker of the utility model gradually bloom key main shaft and connecting lever assembly structure assembling effect figure.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
As depicted in figs. 1 and 2; The described a kind of circuit breaker of the utility model gradually bloom key main shaft and connecting lever assembly structure; Comprise main shaft 1 and connecting lever 2, said main shaft 1 and connecting lever 2 are connected through sleeve, and main shaft 1 outer circumferential face that is positioned at the sleeve joint is provided with the key of gradually blooming outward; The inner hole wall that is positioned at the connecting lever 2 of sleeve joint is provided with the corresponding key of gradually blooming, said outer gradually bloom key and interior gradually bloom key compressing and butt joint.
In an embodiment of the utility model, said main shaft adopts axial INSERTTYPE to be connected with connecting lever, and the corresponding part of outside said, gradually bloom key and the interior key of gradually blooming is removed a tooth engaged 3 respectively.
This circuit breaker main shaft and connecting lever assembly structure location when assembling accurately is easy to distinguish the rigging position of connecting lever, reduces the assembling error, assembles simple, convenient, fast.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and can adopt gear working method, good manufacturability, accuracy of manufacturing is high; The root of inside and outside involute splines tooth is high, and stress is concentrated little, is easy to centering, and spring operating mechanism and involute splines mainshaft mechanism are combined together fully, makes vacuum interrupter obtain desirable driving force and transmission speed.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
