Abstract
The invention discloses a torque dupler that is both labor and time saving, which comprises an internal gear (1), a planetary gear (3) and an eccentric shaft (4) in a small-teeth-difference drive. In the internal gear (1), a wrench 11 is arranged; on the planetary gear (3), an output square hole 31 is arranged; on the ends of the eccentric shaft (4), a square end 41 is arranged; a wrench 61 with a square hole and looped on the square end 41 can rotate about the axial center. The internal gear (1) and the planetary gear (3) employ the gear pair of the small-teeth-difference drive. The gear ratio of the gear pair is equal to the magnification to be increased of the torque. As the torque dupler is provided with two wrenches 11 and 61, when the two wrenches rotate together, as the small-teeth-difference drive is locked into one part, the torque applied by the two wrenches on the places to be twisted is small, and the twisting time is fast; when one of the two wrenches is fixed and another is rotating, as the small-teeth-difference drive is developed into a reduction drive, the torque applied on the places to be twisted is bigger, and the twisting time is long. The torque dupler is both labor and time saving in operation.
Description
Technical field
The present invention relates to various mechanisms in the machinery need increase the occasion of torsional moment, the torque dupler during a kind of specifically laborsaving joint.Because this torque dupler is provided with two hands, when the common rotation of two spanners integral body, the moment of torsion that imposes on the occasion that needs twisting is less, and the twisting time is very fast; Fixed when one of two spanner, during another rotation, the moment of torsion that imposes on the occasion that needs twisting is very big, and the twisting time is longer.So this torque dupler the time can be accomplished effect not only laborsaving but also when saving in operation.
Background technique
In the existing technology, people utilize the occasion that various mechanisms need twist in the conventional spanner twisting machinery.But, because the arm of force of spanner effect is limited, thus want to increase the moment of torsion of the occasion that mechanism need twist become impossible.And the torque dupler in laborsaving when joint adopts two spanners, when two spanners rotate synchronously, twists when comparatively saving; Fixed when one of two spanner, during another rotation, through slowing down, mechanical gain is increased during the spanner rotation, moment of torsion increases thereupon, twists comparatively laborsaving.The torque dupler in this undoubtedly laborsaving when joint; Having overcome in the conventional spanner twisting machinery needs the difficulty of twisting than high pulling torque, particularly for the especially big moment of torsion of needs and the occasion that spanner can't be accomplished, as long as strengthen the driving reduction speed ratio of spanner; Its mechanical gain is improved; The twisting moment of the torque dupler in laborsaving when joint just increases greatly, makes conventional spanner to realize, and the torque dupler when adopting laborsaving joint just becomes reality.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides the torque dupler in a kind of laborsaving when joint.
This torque dupler is to be made up of three assemblies such as internal gear, planetary pinion and eccentric shaft in a kind of few tooth difference transmission.Internal gear is provided with spanner; Planetary pinion is provided with the output square hole; The termination of eccentric shaft is provided with square toes; The spanner that is placed in the band square hole on the square toes can rotate along the axle center.Internal gear and planetary pinion adopt the gear pair of few tooth difference transmission.The velocity ratio of gear pair is identical with the multiple that needs the increase moment of torsion.Because this torque dupler is provided with two spanners, when the common rotation of two spanners integral body, the moment of torsion that imposes on the occasion that needs twisting is less, and the twisting time is very fast; Fixed when one of two spanner, during another rotation, the moment of torsion that imposes on the occasion that needs twisting is very big, and the twisting time is longer.So this torque dupler the time can be accomplished effect not only laborsaving but also when saving in operation.This torque dupler is not seen the reported in literature mistake so far.

Embodiment
Below we combine accompanying drawing that the present invention is carried out detailed description.
Mode of execution:
The torque dupler in laborsaving when joint of seeing figures.1.and.2 be by the internal gear in a kind of few tooth difference transmission 1., 4. 3. planetary pinion wait three assemblies to constitute with eccentric shaft.1. internal gear is provided with spanner 11; 3. planetary pinion is provided with output square hole 31; Eccentric shaft termination 4. is provided with square toes 41; The spanner 61 that is placed in the band square hole on the square toes 41 can rotate along the axle center.3. 1. internal gear adopt the gear pair of few tooth difference transmission with planetary pinion.The velocity ratio of gear pair is identical with the multiple of moment of torsion that needs increase.Because this torque dupler is provided with two spanners 11 and 61, when two spanners 11 and the common rotation of 61 integral body, the moment of torsion that imposes on the occasion that needs twisting is less, and the twisting time is very fast; Fixed when a spanner 11, during another spanner 61 rotations, the moment of torsion that imposes on the occasion that needs twisting is very big, and the twisting time is longer.So this torque dupler the time can be accomplished effect not only laborsaving but also when saving in operation.
Two spanners 11 of torque dupler when being laborsaving joint and 61 whole common working conditions with reference to Fig. 3.Because few tooth difference transmission is locked into one, so during the whole common rotation of two spanners this moment, the moment of torsion that imposes on the occasion that needs twisting is less, and the twisting time is just very fast.
Two wrench 11 of torque dupler and 61 fens other working conditions when being laborsaving joint with reference to Fig. 4.Because few tooth difference transmission is opened into drive state, so this moment, a spanner 11 was fixed, during another wrench 61 rotations, the moment of torsion that imposes on the occasion that needs twisting is very big, and the twisting time is corresponding longer.
It is identical with existing technology that this mode of execution is not stated part.
Most preferred embodiment:
Torque dupler structure during with reference to Fig. 1,2,3 and 4 laborsaving joints is a most preferred embodiment.
It is identical with existing technology that this mode of execution is not stated part.
