Abstract
The invention discloses a high-torque adapter sleeve. The high-torque adapter sleeve comprises a front end sleeve, a flexible gear and a rigid gear sleeve, wherein the front end of the front end sleeve is provided with a matching head, and the rear end of the front end sleeve is provided with a wave generation component; the outer circumference of the wave generation component is in the non-circular shape; the flexible gear is arranged on the outer side of the wave generation component; bearing balls are arranged between the flexible gear and the wave generation component; the wave generation component and the flexible gear are arranged in the rigid gear sleeve; the outer ring of the flexible gear and the inner ring of the rigid gear sleeve are provided with gear teeth; the flexible gear is partially meshed with the rigid gear sleeve. According to the high-torque adapter sleeve, the wave generation component, the flexible gear and the rigid gear sleeve form a harmonic gear structure, and the harmonic gear has higher transmission ratio, and thereby tighter screws or nuts can be unscrewed by means of lower torque if the matching head is jointed into the sleeve with numbers corresponding to nut numbers and the rear end of the rigid gear sleeve is jointed into wrenches with corresponding numbers.
Description
Technical field
The present invention relates to a kind of sleeve, particularly a kind of high torque switching sleeve, belongs to box spanner technical field.
Background technology
In the assembling and maintenance process of product, nut and screw usually there will be the situation that rust is dead and be difficult to turn on; The box spanner application of force difficulty of now using, dynamics is inadequate, usually can cause thread damage, destroys workpiece, and operating efficiency is very low.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of high torque switching sleeve.
Technical solution of the present invention is achieved in that a kind of high torque switching sleeve, comprises front end sleeve, flexbile gear and firm wheel case; The front end of described front end sleeve is provided with cooperating head, and the rear end of front end sleeve is provided with ripple generation part; Being shaped as of the excircle of described ripple generation part is non-circular; Described flexbile gear is arranged on the outside of ripple generation part, between flexbile gear and ripple generation part, is provided with bearing ball; Described ripple generation part and flexbile gear are all arranged in firm wheel case; On the inner ring of the outer ring of described flexbile gear and just wheel case, be provided with the gear teeth, flexbile gear partly meshes with firm wheel case.
Preferably, the excircle of described ripple generation part is shaped as ellipse.
Preferably, described ripple generation part is hollow-core construction.
Preferably, in described cooperating head, be provided with fitting projection.
Preferably, the rear end of described firm wheel case is provided with mating groove.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
High torque switching sleeve of the present invention, by ripple generation part, flexbile gear and firm wheel case, form a kind of harmonic gear structure, because harmonic gear has larger gearratio, and principle that can coaxial line transmission, by adding up of rotating speed, made up the deficiency in moment, and the gear range of harmonic gear is very large, the size of gearratio depends on flexbile gear and the just division of the number of teeth of wheel case; Therefore, by the cooperating head access sleeve corresponding with nut model, and by the spanner of the rear end access respective model of firm wheel case, can realize by less moment tighter screw or nut are turned on.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 2 is the left view of a kind of high torque switching sleeve of the present invention;
Accompanying drawing 3 is that the A-A of a kind of high torque switching sleeve of the present invention is to cutaway view;
Wherein: 1, front end sleeve; 2, flexbile gear; 3, firm wheel case; 4, cooperating head; 5, fitting projection; 6, ripple generation part; 7, mating groove.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As Figure 1-3, a kind of high torque switching sleeve of the present invention, comprises front end sleeve 1, flexbile gear 2 and firm wheel case 3; The front end of described front end sleeve 1 is provided with cooperating head 4, is provided with fitting projection 5 in cooperating head 4, and the rear end of front end sleeve 1 is provided with ripple generation part 6; Described ripple generation part 6 is hollow-core construction, the excircle of ripple generation part 6 be shaped as ellipse; Described flexbile gear 2 is arranged on the outside of ripple generation part 6, between flexbile gear 2 and ripple generation part 6, is provided with bearing ball; Described ripple generation part 6 and flexbile gear 6 are all arranged in firm wheel case 3; The rear end of described firm wheel case 3 is provided with mating groove 7; On the inner ring of the outer ring of described flexbile gear 2 and just wheel case 3, be provided with the gear teeth, flexbile gear 2 and just wheel case 3 part engagements.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
High torque switching sleeve of the present invention, by ripple generation part, flexbile gear and firm wheel case, form a kind of harmonic gear structure, because harmonic gear has larger gearratio, and principle that can coaxial line transmission, by adding up of rotating speed, made up the deficiency in moment, and the gear range of harmonic gear is very large, the size of gearratio depends on flexbile gear and the just division of the number of teeth of wheel case; Therefore, by the cooperating head access sleeve corresponding with nut model, and by the spanner of the rear end access respective model of firm wheel case, can realize by less moment tighter screw or nut are turned on.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
