Description
Technical field
The present invention relates to a kind of transmission device, more particularly to a kind of adjusting device for backlash of dual output transmission mechanism.
Background technology
A kind of transmission mechanism of existing toolroom machine, using two output wheels being arranged in parallel at the same time to a transmission part into
Row transmission, and because the difference of component processing precise degree, or be driven for a long time, cause between the output wheel and the transmission part
Backlash can be produced, and the generation of backlash can directly affect the processing precise degree of toolroom machine.
The method for being generally used for solving backlash, as shown in Figure 1, being to be transmitted the gear teeth 101 of two output wheels 1 with one
When the toothrow 201 of part 2 engages, the gear teeth 101 have the larger depth that is engaged with the toothrow 201, and cause the gear teeth
In no backlash state between 101 and the toothrow 201.Although having solved the problems, such as backlash, this way can but allow institute
State and larger interference is produced between the gear teeth 101 and the toothrow 201, not only cause that driven loads are big, transmission has some setbacks, influence to add
Working medium amount, it is easier to produce abrasion, influence the service life of parts.

Tighten in the shaft sleeve part 322.
Coordinating ginseng Fig. 3, this enters power unit 40 and is arranged between first linkage unit 20 and second linkage unit 30, and
The pedestal 10 is located in including one and is fixedly arranged on the first of the inputting shaft 41 along the inputting shaft 41, one of an axis L extension
Travelling gear 42, one can rotate and be sheathed on the inputting shaft 41 and positioned at the second driving cog of 42 side of the first travelling gear
43, clutch groups being arranged between first travelling gear 42 and second travelling gear 43 44, one of wheel are sheathed on this
Elastic component 45, one between first travelling gear 42 and second travelling gear 43 can move along axis L and be sheathed on this
Inputting shaft 41 and locating ring 46 positioned at 43 side of the second travelling gear and several the locating ring 46 can be made to enter power relative to this
Axis 41 produces the locking part 47 of positioning.First travelling gear 42 is engaged with first driven gear 22, second travelling gear
43 can engage with second driven gear 32, which can be such that second travelling gear 43 connects with first travelling gear 42
Strike up partnership or disconnected from each other, when operating second travelling gear 43 and being separated relative to first travelling gear 42, can operate should
Second travelling gear 43 is rotated relative to first travelling gear 42 towards a first direction, then operates 43 phase of the second travelling gear
When linking integral for first travelling gear 42, the elastic force that the elastic component 45 is contained can be made to drive second travelling gear 43
Relative to first travelling gear 42 towards one in contrast to the first direction second direction rotate.The elastic component 45 is torsion bullet
Spring, and with a first end 451 and one around the second ends 452 of the axis L in contrast to the first end 451, should
First travelling gear 42 perpendicular to the first end face 421 and can supply the first end 451 with a first end face 421 and one
To only the first block face 422, second travelling gear 43 have one relative to the first end face 421 second end face 431 and
One is supported the second block face 432 only perpendicular to the second end face 431 and for the second end 452.The clutch group 44 has number
A the first clutch tooth 441 for being arranged at the first end face 421 and it is several be arranged at the second end face 431 and can with described first from
Close the second engaged clutch tooth 442 of tooth 441.
Again as shown in figures 2 and 5, when the adjusting device for backlash of the present invention integrally assembles completion, or has used one section
Between when, be engaged at the same time on the transmission part 130 using first output wheel 110 and second output wheel 120, and such as Fig. 7 institutes
Show there is backlash between the toothrow 140 of first output wheel 110, second output wheel 120 and the transmission part 130.This
When, which is located at a first position, which is engaged in second travelling gear 43, should
Second travelling gear 43 can link integrally through the clutch group 44 with first travelling gear 42.The locating ring 46 is located at one
To the pressing position for terminating in second travelling gear 43.
When backlash to be eliminated, as shown in fig. 6, the locking piece 23 is first passed through the perforation 181 of the axis hole lid 18 by operator,
, just can be so that first linkage unit 20 be fixed relative to the pedestal 10 generation and spiral shell is arranged in the screw hole 211 of the first rotating shaft 21
Position.
Then, operator unscrews the latch assembly 34 again, second driven gear 32 can by first position along this second
Shaft 31 is moved to a second place, and second driven gear 32 is not engaged in second travelling gear 43, continues, behaviour
Author unscrews the locking part 47, and makes the locating ring 46 by being moved to one to the pressing position for terminating in second travelling gear 43
A disengaged position for being away from second travelling gear 43, operator again determine second travelling gear 43 along axis L towards this
The direction movement of position ring 46, and the second clutch tooth 442 of the clutch group 44 is separated with first clutch tooth 441.Then, grasp
Author operates second travelling gear 43 and is rotated relative to first travelling gear 42 towards the first direction, and makes the elastic component 45
After containing elastic force, then operate second travelling gear 43 and be moved to a centre position towards first travelling gear 42, but
There is a little gap that can be rotated between second clutch tooth 442 and first clutch tooth 441, and it is again that the locating ring 46 is first
Temporary transient locking positioning is on the inputting shaft 41.
When second driven gear 32 is moved back to first position by operator again, and the latch assembly 34 is operated again by the beam
Tight ring 33 is tightened in the shaft sleeve part 322, and after second driven gear 32 is produced positioning relative to second shaft 31, then will
The locking piece 23 is removed, and at this time, since the restraining force of first linkage unit 20 has allayed, then utilizes the elastic component 45
Return and release spring energy and make have opposite force effect between first linkage unit 20 and second linkage unit 30, and the opposite force is passed on
To first output wheel 110, second output wheel 120, and then eliminate backlash (see Fig. 8).
After backlash eliminates, operator operates second travelling gear 43 towards first travelling gear 42 by moving to the compacting again
Position, and make second clutch tooth 442 and first clutch tooth 441 engaged, the biography with regard to Fig. 2 and Fig. 5 can be reverted back to
Dynamic state.
Therefore, the present invention enters the effect of clutch group 44 set by power unit 40 and elastic component 45 using this, when operation should
Second travelling gear 43 is rotated relative to first travelling gear 42, then operates second travelling gear 43 relative to first biography
When moving gear 42 links integral, can contain the elastic component 45 can drive second travelling gear 43 relative to first transmission
The ability that gear 42 is rotated towards the second direction, and can adjust automatically first output wheel 110, the second output wheel 120 and the quilt
The backlash purpose of the toothrow 140 of driving member 130.
In conclusion the adjusting device for backlash of dual output transmission mechanism of the present invention, can solve the problems, such as backlash, and be avoided that
Interference is produced between the toothrow 140 of first output wheel 110, the second output wheel 120 and the transmission part 130, transmission can be reduced
Load and be driven it is smooth, and then can be lifted processing quality and extend parts service life, and eliminate backlash operation it is quite simple
It is single, the purpose of the present invention can be reached really.
