Abstract
The utility model relates to a gear on-off device with a locked position, which comprises a motor gear driven by a motor output shaft through a gear set, a manually operated manual gear and an idle gear capable of being meshed with the motor gear and the manual gear. The gear on-off device further comprises a multi-connection-rod mechanism, wherein one end of the multi-connection-rod mechanism is fixed with the idle gear through an eccentric shaft, and the eccentric shaft distance of the eccentric shaft is larger than the height of a tooth of the idle gear. The gear on-off device with the locked position is simple in structure, reasonable in design and capable of performing conversion between the manual state and the power-driven state of a power-driven operation mechanism.
Description
Technical field
The utility model relates to a kind of gears to engage and disengage device with locking position, belongs to low tension switch attachment technique field.
Background technology
At present both at home and abroad the clutch system of motor-operating mechanism has the row of utilization heart wheel to realize clutch function with the ratchet combined system, also utilize a pair of can axially movable gear or ratchet realize clutch function, have again and utilize unilateral bearing realization clutch function.
Row heart wheel and ratchet combined system can only be used for single direction of rotation usually, and complex structure is huge.The latter can use and realize positive and negative rotation, but owing to be to move axially clutch, so axial dimension is bigger, in flat transmission mechanism, receives spatial constraints and can not adopt.The unilateral bearing space is little, but also can only unidirectional transmission and driving torque less.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure for the deficiency that overcomes prior art, and is reasonable in design, can be with the gears to engage and disengage device of changing between the manual state of motor-operating mechanism and motoring condition with locking position.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of gears to engage and disengage device with locking position; Include the motor gear of motor output shaft through the gear train transmission, manually operated manual gear with can with the idle pulley of motor gear, manual gear engagement, said this device also includes multi-connecting-rod mechanism; One end of multi-connecting-rod mechanism is fixed through eccentric shaft and idle pulley, and the eccentric shaft of said eccentric shaft is apart from a tooth depth greater than idle pulley.
More excellent is; Said multi-connecting-rod mechanism is a three-link mechanism; Be respectively first connecting rod, second connecting rod and third connecting rod that head and the tail link to each other through bearing pin; Wherein first connecting rod is fixed through eccentric shaft and idle pulley; Second connecting rod is long straight-bar, and third connecting rod is that L type connecting rod and third connecting rod can rotate around flex point, when the axle center of the bearing pin of bearing pin, second connecting rod and the connecting rod of first connecting rod and second connecting rod and the fixed pin shaft on the third connecting rod flex point during at same straight line; First connecting rod, second connecting rod and third connecting rod and eccentric shaft be idle pulley and manual gear and motor gear engagement, and no matter motor gear be which kind of direction of rotation can both positive engagement and can not break away from or kill.
More excellent is; When the axle center of the bearing pin of bearing pin, second connecting rod and the third connecting rod of first connecting rod and second connecting rod and the fixed pin shaft on third connecting rod flex point rotation third connecting rod during at same straight line, idle pulley and manual gear are broken away from fully through second connecting rod and first connecting rod and eccentric shaft.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
(1) the utility model is simple in structure, and is reasonable in design;
(2) the utility model makes this device reach the conversion of manual state and motoring condition through the rotation of eccentric shaft;
(3) the utility model is used multi-connecting-rod mechanism, utilizes the state of this device of dead-centre position locking of multi-connecting-rod mechanism, movable originally idle pulley is locked in the position of engagement and can change engagement because of the driving force of different directions.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of gears to engage and disengage device of the utility model shown in accompanying drawing 1-accompanying drawing 4 with locking position; Include the motor gear 1 of motor output shaft through the gear train transmission; Manually operated manual gear 2 with can with the idle pulley 3 of motor gear 1, manual gear 2 engagements; Said this device also includes and is respectively first connecting rod 5, second connecting rod 6 and the third connecting rod 7 that head and the tail link to each other through bearing pin 8; Wherein first connecting rod 5 is fixing with idle pulley 3 through eccentric shaft 4; Second connecting rod 6 is long straight-bar, and third connecting rod 7 can rotate around flex point for L type connecting rod and third connecting rod 7, when the axle center of the bearing pin 8 of first connecting rod 5 and bearing pin, second connecting rod 6 and the third connecting rod 7 of second connecting rod 6 and the fixed pin shaft on third connecting rod 7 flex points during at same straight line; First connecting rod 5, second connecting rod 6 and third connecting rod 7 and eccentric shaft 4 be idle pulley 3 and manual gear 2 and motor gear 1 engagement, and no matter motor gear 1 be which kind of direction of rotation can both positive engagement and can not break away from or kill.The eccentric shaft of said eccentric shaft 4 is apart from a tooth depth greater than idle pulley 3
The course of work:
The released state course of action that is forwarded to accompanying drawing 4 by the engagement of accompanying drawing 2 is: third connecting rod 7 turns clockwise; Pulling second connecting rod 6 causes eccentric shaft 4 to clockwise rotate with first connecting rod 5; Idle pulley 3 turns clockwise along eccentric shaft 4 roundlet centers, separates fully with manual gear 2 up to idle pulley 3;
The engagement course of action that is forwarded to accompanying drawing 2 by the released state of accompanying drawing 4 is: third connecting rod 7 is rotated counterclockwise; Promoting second connecting rod 6 causes eccentric shaft 4 to rotate counterclockwise with first connecting rod 5; Idle pulley 3 is rotated counterclockwise along eccentric shaft 4 roundlet centers; The axle center of the fixed pin shaft on the bearing pin 8 of the bearing pin 8 of first connecting rod 5 and second connecting rod 6, second connecting rod 6 and third connecting rod 7 and third connecting rod 7 flex points is at same straight line, and this moment, idle pulley 3 meshed with manual gear 2 fully.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
