Problems solved by technology

[0003] Aiming at the problems existing in the gear transmission structure of the prior art reducer, a certain transmission ratio must comply with a certain diameter, a relationship between the number of teeth, the diameter of the number of teeth of the driven gear is often too large, there are many restrictions on the arrangement of the gears, and the structure of the multi-stage cascade reducer is bulky, etc. , the present invention provides a variable-speed transmission mechanism, which utilizes the cooperation between two or more sets of gears and is not limited by the relationship between the number of teeth and the diameter. It can also keep its own size from synchronously increasing under the condition of flexibly changing the transmission ratio. The purpose of variable speed transmission is achieved, and the machine designed with this transmission mechanism will be lighter and more compact

Embodiment 1

[0066] see figure 1 , 3 As shown in -5, one eccentric wheel 12 is fixedly installed on the input shaft 11 corresponding to each of the output gears 22, and the outer circumferential surface of each of the output gears 22 is aligned with the corresponding eccentric wheel 12. Teething on the outer circumferential surface.

[0067] The output gear 22 is provided with an output gear box 25, and the output shaft 21 is connected to both sides of the output gear box 25 through bearings 26. The output gear box 25 is provided with a number of accommodation cavities along the length direction of the output shaft 21. 251, each of the output gears 22 is correspondingly installed in one of the accommodating cavities 251, and the side of the accommodating cavity 251 close to the input shaft 11 is formed for connecting the output gear 22 with the eccentric wheel 12 Fitted opening 252 . The output gear 22 is installed on the accommodating cavity 251, and the purpose of controlling the tran...

Embodiment 2

[0074] see Image 6 As shown, an eccentric wheel 12 is fixedly installed on the input shaft 11, and different transmission ratios are achieved by controlling the fit of the eccentric wheel 12 and different output gears 22 on the output shaft 21; what is changed here is the distance between the eccentric wheel and the output gear. transmission relationship.

[0075] The shape and size of each output gear on the output shaft need to be exactly the same.

[0076] As a preferred embodiment, each of the eccentric wheels 12 in the above two groups of embodiments is composed of an eccentric wheel main body 121 and a rolling bearing 122 sleeved on the periphery of the eccentric wheel main body 121, see Figure 7 , the outer diameter of the rolling bearing 122 is equal to the diameter of the eccentric wheel 12 . Using rolling bearings, the resistance is smaller, the friction loss can be reduced during operation, and the use and maintenance are more convenient.

Abstract

The invention discloses a variable-speed transmission mechanism, and belongs to the field of speed reducers. The mechanism comprises an input assembly and an output assembly, the input assembly comprises an input shaft and an eccentric wheel arranged on the input shaft, the output assembly comprises an output shaft and more than two output gears, and the centers of the output gears are arranged onthe output shaft; and the input shaft is parallel to the output shaft. The variable-speed transmission mechanism has the beneficial effects that more than two groups of gears are matched and are notare not limited by the tooth number and diameter relation, the size of the variable-speed transmission structure cannot be synchronously increased under the condition that the transmission ratio is flexibly changed, the purpose of variable-speed transmission is achieved, and meanwhile, a machine using a variable-speed transmission structure is smaller and lighter.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a variable-speed transmission mechanism. Background technique [0002] With the development of mechanical technology for hundreds of years, various transmission methods are already very rich, but in the robot market that has developed rapidly in the past ten years and is predicted to be ubiquitous in the future, the traditional gear multi-stage transmission reduction However, most of the market demand is occupied by expensive RV reducers and harmonic reducers. And this itself is caused by the characteristics of the existing gear transmission. There is a corresponding relationship between the transmission ratio of the traditional gear and the gear diameter. Therefore, the traditional gear needs to meet a certain diameter relationship in order to design a gear that meets the transmission requirements. The structure also requires that the minimum number of teeth of the gear must meet a cert...
