Description
Technical field
The utility model relates to a kind of denoising device that reduces the transmission noise when meshed transmission gear, belongs to gear manufacturing and drive technology field.
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: the machining accuracy that 1, improves gear on correct, the rational basis of gear technique parameter.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 the accuracy limitations of the process equipment of manufacture cost and manufacturing gear, if improve the machining accuracy of gear or the assembly precision between driving gear in order to reduce gear noise, will increase substantially gear like this and the manufacture cost of the part that matches with gear.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
At this problem that needs prior art to solve, the purpose of this utility model is to provide a kind of duplicate gear device that reduces the gear transmission noise, and this apparatus structure is simple, compactness, working stability, reliability height, low manufacturing cost.
The technical scheme in the invention for solving the technical problem is: a kind of duplicate gear device that reduces the gear transmission noise, it comprises transmission shaft, on transmission shaft, be with axle sleeve, on the transmission shaft of axle sleeve both sides, be arranged with pinion respectively, outside the pinion of both sides, be separately installed with master gear, two master gears and transmission shaft are interference fit, between the pinion of both sides and master gear, be respectively equipped with packing ring, described master gear is identical with adjacent pinion tooth portion parameter, on described axle sleeve, overlap and have elastic component, be respectively equipped with jack on the pinion of described axle sleeve both sides, two of described elastic element is located in respectively in the jack of both sides pinion.
The described duplicate gear device that reduces the gear transmission noise, described elastic element is a torque spring, two of described torque spring is divided in the jack that supplementary biography is located at the both sides pinion.
The utility model is after assembling finishes, when cooperating assembling with other parts, need one of them pinion is fixed, another pinion is rotated a certain angle and temporarily fixes along the rotation direction of elastic element, treat to unclamp again after the master gear of both sides and pinion and the gear that is meshed with it assemble.Utilize the torsion (direction of torsion is opposite with the rotation direction of torsion spring) of elastic element like this, two pinions have been eliminated two master gears respectively and have been mediated the inter-lobe clearance of gear with it mutually, thereby reduce the effect of noise when playing work; Axle sleeve plays leading role and two pinions are spaced apart to torsion spring.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the duplicate gear device that reduces the gear transmission noise of the present utility model, it comprises transmission shaft 9, on transmission shaft 9, be with axle sleeve 5, on the transmission shaft of axle sleeve 5 both sides, be arranged with pinion 3 and pinion 6 respectively, master gear 1 is installed outside pinion 3, the tooth portion parameter of master gear 1 and pinion 3 is identical, between master gear 1 and pinion 3, be provided with packing ring 2, master gear 8 is installed outside pinion 6, the tooth portion parameter of master gear 8 and pinion 6 is identical, is provided with packing ring 7 between pinion 6 and master gear 8.Be with torque spring 4 on axle sleeve 5, be respectively equipped with jack 10 on pinion 3 and pinion 6, two of torque spring 4 is located in respectively in the jack 10 of both sides pinion.
This duplicate gear apparatus structure that reduces the gear transmission noise is simple, compactness, working stability, reliability height, low manufacturing cost.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
Claims (2)
