Abstract
The invention discloses a rotary unloading mechanism between boxes. The mechanism comprises a rotary shaft, an inner shaft sleeve, an inner clutch, an outer clutch and an outer shaft sleeve. The inner shaft sleeve and the outer shaft sleeve are fixed to the head box through screws. Rolling bearings are arranged on the inner sides of the two ends of the inner shaft sleeve in a sleeved mode. Inner rings of the rolling bearings are inlaid in the rotary shaft. The rotary shaft is driven by a motor through a coded disc and is connected with the inner clutch through a pin. The inner clutch is connected with the outer clutch through a key groove structure. The outer clutch is fixed to the body box through a screw. The body box is sleeved with a rolling bearing, and an outer ring of the rolling bearing is inlaid in an inner hole of the outer shaft sleeve. According to the mechanism, connecting shaft bending deformation caused by overloading and motor heavy load can be avoided.
Description
Technical field
The present invention relates to the unloading mechanism of turning between a kind of casing, in particular for head case and the body of multimode bionic amphibious robot
The unloading mechanism of turning of case.
Background technology
At present, robot has been applied to the aspects such as military affairs, space flight, medical treatment, rescue and relief work and community service, and to new neck
Territory is stretched.Day by day exhausted along with land resources, exploring exploitation ocean will be the wide new application of future robot.Imitative
Raw fish relies on fin, the coordination exercise of body and afterbody realizes under water efficiently, quickly, maneuverability travelling；Bionical dolphin is in danger
Dangerous, narrow, the complicated detection in underwater environment, detective, salvage and maintenance has a good application prospect.The most domestic
The device people developed outward has machine fish, snake robot, robotic dolphin, Mechanical tortoise, crab-liked robot, machine Blatta seu periplaneta, machine Lobster etc. several
Kind.Although these model machines have certain aquatic environment adaptive functions, but the most original, there are bigger limitation and deficiency, mainly
It being embodied in: 1) actual performance such as speed, mobility, landform adaptability etc. be relatively poor；2) amphibious mobility can not be same
Time be protected.To this end, require that robot has to integrate efficient, quick, the flexible and high-tech of good environment adaptation ability
Development function is explored in skill ocean.Exploitation one can in water travelling with imitative fish and imitative dolphin both modalities which and have operating function,
Simple in construction, amphibious robot with low cost meet trend and the needs of social production life of robot development.Therefore, I
Originality propose one and turn mechanism, the horizontal hunting of robot can be converted to vertical oscillation, it is achieved imitative porpoise.
Difficult point therein is, radial load direction produced by two kinds of forms is different, needs a kind of new-type mechanism to carry out union joint body
Casing, and by load unloading radially, it is to avoid the connecting shaft of transmission moment of torsion produces flexural deformation and the generation of motor heavy duty.
Chinese patent publication No. CN103633774A also discloses that a kind of unloading mechanism on motor output shaft, in being positioned at
Between axle sleeve, at the two ends outer sheath of axle sleeve equipped with rolling bearing, rolling bearing outer ring is embedded at the endoporus of bearing, at bearing
Being provided with the manhole appendix of transmission band or driving-chain, at the inner chamber of bearing, the outside fixed cover being positioned at axle sleeve passes equipped with living with transmission band
The wheel that dynamic chain matches.By axle sleeve by bonded on the output shaft of motor during installation, motor is screwed and is connected to bearing side
Face, transmission band or chain are enclosed within the wheel outside axle sleeve, owing to having bearing and bearing outside axle sleeve, the load pulling force of transmission band or chain
Being born by bearing completely, motor output shaft is only made to rotate to drive, and overcomes motor output shaft and bears the shortcoming of radial load, improves
Service life of motor, simple in construction.Above-mentioned patent solves motor output shaft and bears the shortcoming of radial load, but does not relate to
And to the relative motion between casing.And the technical problem to be solved is to provide a kind of relative rotation that can complete between casing
Turn, and ensure that rotary shaft is not subject to the unloading mechanism of turning of radial load.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, can complete rotating against between casing, and ensure
Rotary shaft is not subject to the unloading mechanism of turning between the casing of radial force.
Technical scheme is as follows: the unloading mechanism of turning between a kind of casing, including rotary shaft, and internal axle sleeve, interior clutch,
Outer clutch, outer shaft, it is characterised in that: internal axle sleeve and outer shaft are fixedly installed on a case, at the two ends inner sleeve of internal axle sleeve
Equipped with rolling bearing, rolling bearing inner ring is embedded in rotary shaft, and rotary shaft is driven by motor by code-disc；Interior clutch is set with
In rotary shaft, fixing and be connected between interior clutch with outer clutch, outer clutch is fixedly installed on body case；One end of body case is equipped with turning
Dynamic bearing, the outer ring of rolling bearing is embedded at the endoporus of outer shaft.
One end of described rotary shaft is helicitic texture, with the axial location that nut screw connection can realize rotary shaft.
Beneficial effects of the present invention: the rotary shaft in the present invention is axially positioned by nut, by interior clutch and outer clutch to
Body case transmission moment of torsion, owing to there being bearing outside one end of rotary shaft and body case, the radial load that body case is brought via bearing and
Outer shaft reaches a case, and rotary shaft only transmits moment of torsion, thus connecting shaft can be avoided because loading the excessive flexural deformation caused and electronic
Machine heavy duty.

Fig. 1 is the structural representation of the specific embodiment of the invention.
Labelling in figure: 1, motor, 2, code-disc, 3, rotary shaft, 4, internal axle sleeve, 5, head case, 6, outer shaft, 7, body case,
8, outer clutch, 9, interior clutch.
Detailed description of the invention
As it is shown in figure 1, the unloading mechanism of turning between a kind of casing, including rotary shaft 3, internal axle sleeve 4, interior clutch 9, outer clutch
8, outer shaft 6, described internal axle sleeve 4 and outer shaft 6 are fixing with head case 5 by screw, the two ends inner sleeve of described internal axle sleeve 4
Equipped with rolling bearing, rolling bearing inner ring is embedded in rotary shaft 3, and described rotary shaft 3 is driven by motor 1 by code-disc 2；
Described rotary shaft 3 is connected by pin with interior clutch 9, and described interior clutch 9 is connected by keyway arrangements between outer clutch 8,
Described outer clutch 8 is fixed with body case 7 by screw；One end of described body case 7 is equipped with rolling bearing, the outer ring edge of rolling bearing
It is embedded at the endoporus of outer shaft 6.
Described motor 1 drives rotary shaft 3 to rotate by code-disc 2, and described rotary shaft 3 is carried by interior clutch 9 and outer clutch 8
