Description
[technical field]
The utility model belongs to mechanical field, is specifically related to the mechanism of the torque pulse that a kind of elimination is produced by gear clearance.
[background technique]
In mechanical transmission mechanism, meshed transmission gear is the more typical kind of drive of one, but this transmission is affected because the movement clearance between gear tooth result in transmission accuracy.Gear can produce friction in transmission process, and the error produced when Gear Processing, and this backlash that all result in gear becomes large.Eliminate mechanical mechanism all more complicated of gear clearance in the market, cost is higher simultaneously.At aerospace field, mechanical motion is more harsh for the requirement of kinematic accuracy, but the precision that great majority eliminate the mechanical mechanism of gear clearance is difficult to reach desirable state.Because the movement clearance between gear tooth can produce certain torque pulse for transmission, so how to eliminate this torque pulse to become precision equipment device problem demanding prompt solution.
[model utility content]
The purpose of this utility model is to overcome above-mentioned deficiency, the mechanism of the torque pulse providing a kind of elimination to be produced by gear clearance, the gap between two engaging gears can be eliminated, and then the input torque of pulse can be had to obtain a constant Driving Torque from one.
In order to achieve the above object, the utility model comprises the input shaft with small gear, and first spur wheel of empty set on output shaft and the second spur wheel, small gear can engage the first spur wheel and the second spur wheel simultaneously, output shaft is fixed with the hub driving it to rotate, be connected by the first spring between hub with the first spur wheel, be connected by the second spring between the first spur wheel with the second spur wheel.
The card of described first spur wheel offers cell body, hub is provided with the pin coordinated with cell body.
When described input shaft rotates counterclockwise, the first spring is compressive state, and the second spring is extended state.
The card of described hub and the first spur wheel all offers the first spring fixing groove, and the two ends of the first spring are separately fixed in the first spring fixing groove on hub and the first spur wheel.
The card of described first spur wheel and the second spur wheel all offers the second spring fixing groove, and the two ends of the second spring are separately fixed in the second spring fixing groove on the first spur wheel and the second spur wheel.
When described input shaft rotates clockwise, the first spring is extended state, and the second spring is compressive state.
Compared with prior art, the utility model is rotated by input shaft, small gear is made to engage the first spur wheel and the second spur wheel, when input shaft produces torque pulse time, torque pulse can be eliminated by the first spring and the second spring, the small gear of this device engages the first spur wheel and the second spur wheel simultaneously, effectively can eliminate gear clearance, precision is high simultaneously, and it is little that it has volume, and structure is simple, the advantage that number of parts is few, and structure is simple, easy to install, simultaneously with low cost.
Further, the utility model has pin, enables this device eliminate the gear clearance of positive and negative both direction.

Fig. 2 is the utility model gears meshing Local map;
Fig. 3 is the cooperation schematic diagram of the utility model first spur wheel, the second spur wheel and hub.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, Fig. 2 and Fig. 3, the utility model comprises the input shaft 8 with small gear 9, and first spur wheel 4 and second spur wheel 5 of empty set on output shaft 6, small gear 9 can engage the first spur wheel 4 and the second spur wheel 5 simultaneously, output shaft 6 is fixed with the hub 2 driving it to rotate, be connected by the first spring 3 between hub 2 with the first spur wheel 4, be connected by the second spring 7 between the first spur wheel 4 with the second spur wheel 5, the card of the first spur wheel 4 offers cell body, hub 2 is provided with the pin 1 coordinated with cell body, the card of hub 2 and the first spur wheel 4 all offers the first spring fixing groove, the two ends of the first spring 3 are separately fixed in the first spring fixing groove on hub 2 and the first spur wheel 4, the card of the first spur wheel 4 and the second spur wheel 5 all offers the second spring fixing groove, and the two ends of the second spring 7 are separately fixed in the second spring fixing groove on the first spur wheel 4 and the second spur wheel 5.
When input shaft 8 rotates counterclockwise, the first spring 3 is compressive state, and the second spring 7 is extended state; When input shaft 8 rotates clockwise, the first spring 3 is extended state, and the second spring 7 is compressive state.
When input shaft 8 rotates counterclockwise, the pulsating torque of small gear 9 directly passes to the second spur wheel 5, and then, the second spur wheel 5 drives the first spur wheel 4 to rotate by the second spring 7 again.Because small gear 9 does not directly drive the first spur wheel 4 to rotate in this sense of rotation, and the first spur wheel 4 can slightly do free rotation relative to small gear 9, so the pulsation of torque is just eliminated by the first spring 3 and the second spring 7, hub 2 has a pin 1 engaged with a cell body of the first spur wheel 4, pin 1 drives hub 2 and output shaft 6 to rotate clockwise with regard to level and smooth with constant torque.
When input shaft 8 rotates in a clockwise direction, small gear 9 just directly drives the first spur wheel 4 to rotate, and in this case, the first spur wheel 4 drives hub 2 and output shaft 6 to rotate by the first spring 3 clockwise.And the pulsation input in first spring 3 filtering input torque.
