Description
Technical field: the utility model relates to a kind of double speed moment of torsion and presets adjustable torque dupler, a kind of instrument when it is the screw thread pair installation.
Background technology: present existing torque dupler is when carrying out the screw thread pair installation, because torque dupler itself is exactly a decelerator, when by power shaft (sun gear) input torsion, output shaft (planet carrier) is just pressed the gearratio rotation.For example: when the torque dupler gearratio is i, the velocity of rotation of power shaft is V
1, output shaft (planet carrier) output speed V
2=V
1/ i, when screw thread pair in installation process, existing existing torque dupler overall process is installed can only be with V
1The speed operation of/i, efficient is low.And existing torque dupler is by the torque spanner input torque, multiply by the multiplication factor of torque dupler again with moment of torsion shown in the torque spanner, draws the real output value of output shaft, and it is pretty troublesome therefore to work.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of double speed moment of torsion to preset adjustable torque dupler, it can rotate with fast speed by output shaft when the screw thread pair installation process need only less moment of torsion, when the needs high pulling torque is exported, output shaft rotates with the gearratio number of torque dupler again, this has just overcome existing torque dupler can only be with a speed operation, ineffective shortcoming.The purpose of this utility model be achieved in that the double speed moment of torsion preset adjustable torque dupler by: box spanner, counter-force arm, ring gear, second level planetary wheel carrier, first order planetary wheel carrier, sun gear, ratchet spanner, special-purpose moment of torsion preset adjustable spanner, back-up ring, first order planetary gear, second level planetary gear and constitute.Second level planetary gear is installed on the planetary wheel carrier of the second level, then it is packed in the ring gear, first order planetary gear is installed on the first order planetary wheel carrier, again it is packed in the ring gear, second level pinion frame is connected with first order pinion frame in ring gear, back-up ring is contained in the ring gear end, sun gear is installed in the first order planetary wheel carrier hole, sun gear and the engagement of first order planetary gear, counter-force arm is installed in the ring gear outside, box spanner is contained in the output of second level planetary wheel carrier, ratchet spanner is contained in the input that exposes of first order planetary wheel carrier, special-purpose moment of torsion presets in the square hole that adjustable spanner is positioned on ratchet spanner, and special-purpose moment of torsion presets adjustable spanner and also can be installed in the sun gear square hole.This product structure is simple, easy to use, it can rotate with fast speed by output shaft when the screw thread pair installation process need only less moment of torsion, when the needs high pulling torque is exported, output shaft rotates with the gearratio number of torque dupler again, having overcome existing torque dupler can only be with a speed operation, ineffective shortcoming.This product is furnished with special-purpose output torque simultaneously and presets the torsion-adjustable spanner, and indicating torque value on this spanner is the actual value of output shaft, needn't calculate separately, has reduced artificial computational process, thereby has improved operating efficiency, and is swift to operate, convenient.

The specific embodiment: describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, the double speed moment of torsion preset adjustable torque dupler by: box spanner (1), counter-force arm (2), ring gear (3), second level planetary wheel carrier (4), first order planetary wheel carrier (5), sun gear (6), ratchet spanner (7), special-purpose moment of torsion preset adjustable spanner (8), back-up ring (9), first order planetary gear (10), second level planetary gear (11) and constitute.Second level planetary gear (11) is installed on the second level planetary wheel carrier (4), then it is packed in the ring gear (3), first order planetary gear (10) is installed on the first order planetary wheel carrier (5), again it is packed in the ring gear (3), be connected with first order planetary wheel carrier (5) at ring gear (3) second level, lining planetary wheel carrier (4), back-up ring (9) is contained in the end of ring gear (3), and it blocks planetary wheel carrier, and it is not scurried out.Sun gear (6) is installed in first order planetary wheel carrier (5) hole, sun gear (5) and first order planetary gear (10) engagement, counter-force arm (2) is installed in ring gear (3) outside, box spanner (1) is contained in the output of second level planetary wheel carrier (4), ratchet spanner (7) is contained in the input that exposes of first order planetary wheel carrier (5), special-purpose moment of torsion presets adjustable spanner (8) need only less moment of torsion and output shaft is installed in it when rotating with fast speed and carries out work in the square hole of ratchet spanner (7) in the screw thread pair installation process, when output shaft needs high pulling torque when output, more special-purpose moment of torsion is preset in the square hole that adjustable spanner (8) is installed in sun gear (6) and carry out work.This has just reached the purpose of double speed.
The utlity model has two moment of torsion input positions:
1, directly rotates planetary wheel carrier; Because first order planetary wheel carrier is a planetary wheel carrier is again power shaft, it can need less moment of torsion and velocity of rotation when very fast at screw thread pair installation process output shaft, and directly rotating ratchet spanner planetary wheel carrier can reach the very fast purpose of output shaft velocity of rotation.
2, be to rotate input torque by sun gear; Because be to have passed through first order sun gear-planetary gear-ring gear to slow down, so output wheel speed is lower, still, output torque is bigger.If the speed reducing ratio of the first order is i
1, the rotating speed of output shaft improves i when so directly rotating the planetary wheel carrier ratio by the sun gear input torque
1Doubly.Preset the torsion-adjustable spanner because be furnished with moment of torsion again, be carved with the output torque of output shaft when rotating sun gear on the spanner, before the work required output torque being preset the value that indicates on the torsion-adjustable spanner by moment of torsion presets and finishes, when rotating input torque by sun gear, when the sound of hearing " click ", output shaft has just been finished required torque output.Needn't calculate, easier, reliable.
