Description
Technical field
The utility model relates to the meshed transmission gear device, is meant a kind of Gear combination that reduces the gear transmission noise especially.
Background technique
Gear transmission is the power transmission mode of mechanical industry extensive use, but high gear transmission running the time often produces noise thereupon.
The noise that produces when reducing gear transmission mainly contains 3 following measures:
1, on correct, the rational basis of gear technique parameter, improves the machining accuracy of gear.
2, at the assembly precision between the raising gear on correct, the rational basis of gear technique parameter.
3, on correct, the rational basis of gear technique parameter, increase the auxiliary denoising device of gear.
Because manufacture cost and make the accuracy limitations of the process equipment of gear, the machining accuracy of gear or the assembly precision between driving gear will increase substantially gear and the manufacture cost of the part that matches with gear if improve in order to reduce gear noise.What generally generally adopt is the auxiliary denoising device of increase on driving gear, in the time of so just can reaching the meshed transmission gear that adopts grade of accuracy manufacturing generally commonly used, and the purpose that its transmission noise is but very little.
The model utility content
Technical problem to be solved in the utility model provides a kind of Gear combination that reduces the gear transmission noise.
In order to address the above problem, the utility model is taked following technological scheme:
A kind of Gear combination that reduces the gear transmission noise, be provided with the master gear and the pinion of center through hole above comprising, also comprise first packing ring, damping element, second packing ring and shaft block ring, the axle that protrudes in the flank of tooth is arranged on the master gear, there is the collar groove axle upper end portion, above-mentioned first packing ring, damping element, second packing ring and shaft block ring are enclosed within on the axle of master gear from right to left successively, and shaft block ring is stuck in the collar groove.
Described elastic element is between first packing ring and pinion.
Described damping element is between the pinion and first packing ring.
Described damping element is an elastic element.
Described elastic element is a shock-absorbing spring.
Described shock-absorbing spring is the dish spring.
Many one of the number of teeth of the described gear ratio master gear that is sheathed on the pinion on the main gear shaft.
The beneficial effects of the utility model are: elastic element compressive deformation owing to himself when pinion produces relative rotation with respect to master gear has produced the stable damping that continues to pinion, make pinion whenever can both play effective elimination master gear and the gear that is engaged with inter-lobe clearance effect and pinion is steadily rotated with respect to master gear, even dynamical element produces vibration when driving the master gear rotation, also can be absorbed, slow down, the purpose that realize reducing vibration, reduces noise by elastic element.

Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
With reference to Fig. 1-Fig. 3, a kind of Gear combination that reduces the gear transmission noise, be provided with the master gear 1 of center through hole above comprising, first packing ring 3, pinion 2, damping element, second packing ring 5 and shaft block ring 6, the axle 7 that protrudes in the flank of tooth is arranged on the master gear 1, there is collar groove 8 the axle upper end portion, above-mentioned first packing ring 3, pinion 2, damping element, second packing ring 5 and shaft block ring 6 are enclosed within on the axle 7 of master gear from right to left successively, shaft block ring 6 is stuck in the collar groove 8, when damping element can be contained in axle in the collar groove 8 of master gear with ring washer 6, reach the compressive deformation amount of design to keep damping element after master gear 1 direction produces certain compressive deformation.Described damping element is an elastic element, it is between the pinion 2 and second packing ring 5, rely on its deformation pressure to be applied directly on the pinion 2, another side presses second packing ring 5, master gear 1 is used for and other gear engagement transferring power, many one of the number of teeth of pinion 2 gear ratio master gears 1, can be around the rotational axis rotation of master gear 1, pinion 2 was eliminated the inter-lobe clearance of master gear 1 and the gear that is engaged with and then is played the purpose that reduces the gear transmission noise in auxiliary being used to down of elastic element, elastic element compressive deformation owing to himself when pinion 2 produces relative rotation with respect to master gear 1 has produced the stable damping that continues to pinion, make pinion whenever can both play effective elimination master gear and the gear that is engaged with inter-lobe clearance effect and pinion is steadily rotated with respect to master gear, even dynamical element produces vibration when driving master gear 1 rotation, also can be absorbed by elastic element, slow down, realize reducing vibration, reduce the purpose of noise.First packing ring 3 is spaced apart with master gear 1 and pinion 2, and second packing ring 5 is spaced apart with ring washer 6 with damping element and axle; Axle 6 position-limiting actions of ring washer.
Above-mentioned elastic element can be shock-absorbing spring, and shock-absorbing spring can be dish spring 4.
Embodiment 2:
With reference to Fig. 3, different with the foregoing description is, the pinion 2 of present embodiment is positioned at the elastic element left side, and elastic element simultaneously presses pinion 2, and another side presses master gear 1 face of gear by second packing ring 5.
For above-mentioned two kinds of embodiments, dish spring 4 curved being buckled on the pinion 2 guarantee that the dish Huang fully contacts with second packing ring 5 with pinion 2.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
