Problems solved by technology
The vibration and noise reduction gear structure disclosed in this patent document is only suitable for disc-shaped flat gears, and the vibration and noise reduction structure is complicated to process, and the vibration and noise reduction effect is not ideal
[0005] In addition, the existing gears are of integral structure
If a single tooth is severely worn or damaged, the entire gear will need to be replaced, increasing costs and repair time

Embodiment Construction
[0061] Illustrative, non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings, and further descriptions according to the present invention will be described.
[0062] figure 1 It shows a meshing schematic diagram of a pair of elastic spacer type damping gears according to the present invention, wherein the driving gear 1 and the driven gear 2 are meshed. Here, taking the driving gear 1 as an example, refer to Figure 1-4 The structure of the elastic interlayer type damping gear according to the present invention will be described in detail.
[0063] The gear 1 includes a gear base 10 , an involute profile 11 and an elastic spacer 12 . The gear base 10 includes a circular main body 13 and a plurality of tooth bases 14 uniformly distributed along the circumferential direction of the circular main body 13 . see image 3 , the two sides of each of the plurality of tooth bases 14 are respectively provided with i...

The invention provides an elastic interlayer type vibration reduction gear and a method for decreasing gear transmission errors by using the gear. The elastic interlayer type vibration reduction gear comprises a gear base body, involute outline bodies and an elastic interlayer, wherein the gear base body comprises a round main body and multiple gear tooth base portions evenly distributed in the peripheral direction of the round main body, the involute outline bodies are respectively arranged on two sides of each gear tooth base portion, and the elastic interlayer is arranged between the gear tooth base portions and the involute outline bodies in a sealing mode to enable each gear tooth base portion, the involute outline bodies on two sides and the elastic interlayer to form the gear. The vibration reduction gear can reduce and even eliminate vibration through the elastic interlayer and further decrease the gear transmission errors. In addition, due to the fact that the gear is of a combined structure, only one involute outline body is required to be replaced if one gear is abraded severely or damaged, the cost is saved, operation is simple and convenient, and the maintenance time is shortened.
Description
technical field [0001] The invention relates to the field of gear transmission, and more specifically, relates to an elastic interlayer type damping gear and a method for reducing gear transmission errors. Background technique [0002] Vibration, noise and comfort (NVH) is one of the concerns of major vehicle manufacturers and parts companies in the international automotive industry. As an important transmission part of the modern automobile industry, gears are one of the main sources of vibration and noise during the operation of automobiles. The dynamic behavior and working performance of gears have an important impact on the entire vehicle. For a pair of gears that are actually meshing, there are inevitably various errors, such as tooth profile errors, base joint errors, and central moment errors, which cause variations in the actual meshing process. These variations will cause great vibration, dynamic load and noise during the transmission process of the involute gear, ...
