Embodiment 1

[0020] Embodiment one, a kind of large-scale gear transmission (seeing Fig. 1) of two gears uninterrupted power, two rotating shafts 7,8 that the bearing 9 of base, base are arranged, power is transmitted to rotating shaft 8 from rotating shaft 7. Two opposite rotating shafts 7,8 have circular gears 1,3,4,6 and have constituted a two-speed circular gear mechanism. Rotating shaft 7,8 also has eccentric gear 2,5 and has formed eccentric gear mechanism (seeing figure 2). The eccentric gear mechanisms of these two-speed circular gear mechanisms that are arranged in parallel and output with the steering and a transition gear are all gear mechanisms that are constantly meshed. The driving gears 4, 5, 6 in the two-speed circular gear mechanism and the eccentric gear mechanism are connected with the rotating shaft 7 through the one-way overrunning clutch X, Y, Z, and the driven gears 1, 2, 3 are fixedly connected with the rotating shaft 8. The n-direction speed of the rotating shaft ...

Embodiment 2

[0021] Embodiment two, a gear transmission (seeing Fig. 1, 2, 3, 4, 5) of two gears uninterrupted power, has two shafts 7,8 that the bearing of gear case, gear case is provided with, shaft 7, Shaft 8 is the input shaft and the output shaft respectively. Shafts 7 and 8 are provided with mutually meshing circular gears 1, 3, 4, 6 and eccentric gears 2, 5, forming a gear mechanism for power transmission with steering output. In the two-stage circular gear mechanism formed by the relatively rotating shafts 7 and 8 and the eccentric gear mechanism corresponding to the transition gear in parallel, each gear mechanism has a gear 4, 5, 6 and the shaft 7 through a roller type two-way The overrunning clutch X, Y, Z is connected. The overrunning clutch of gear 4,5,6 is made of the shell 14 that is fixedly connected with gear, the star wheel 13 that is connected with axle 7, the roller 16 that is arranged between star wheel and shell and constitutes. There is also a claw 15 between the ...

Embodiment 3

[0025]Embodiment three, a kind of gear transmission (seeing Fig. 36, also referring to Fig. 8) of four gears uninterrupted power, has gear case, the bearing of gear case is equipped with input shaft 87 and output shaft 88, these two opposite The shaft that rotates and transmits the power is provided with four forward-rotating circular gear mechanisms, and a forward-rotating oval gear mechanism is also juxtaposed in the middle of every adjacent two-grade circular gear mechanism. The bearings, input shaft, output shaft, four pairs of circular gears, and three pairs of non-circular gears of the gear box respectively constitute a circular gear mechanism with four gears and a non-circular gear mechanism with three transition gears, and together with the gear box A four-stage transmission is formed. The gear transmission transmits power in one direction, and the power is transmitted from the shaft 87 to the shaft 88 . From the first gear circular gear mechanism to the fourth gear c...

Abstract

The present invention has pedestal or gear box with at least two shafts set via bearings, shafts connected via gears to constitute gear mechanism, at least two circular gear mechanisms from the input shaft to the output shaft, non-circular gear mechanism configured corresponding the circular gear mechanisms, overrunning clutches in the circular gear mechanisms and non-circular gear mechanism, and control mechanism. The non-circular gear with speed increase or decrease process is used for the transition of speed and combined with automatic combination and separation to realize the uninterrupted power speed change. The non-circular gear mechanism has maximum transmission ratio greater than that of the low speed circular gear mechanism and minimum transmission ratio higher than that of the high speed circular gear mechanism, resulting in reliable and smooth gear speed change.

Description

Technical field: [0001] The invention relates to a multi-speed gear transmission, especially a gear transmission that can change gears and change the transmission ratio without cutting off the power. Background technique: [0002] Existing gear transmissions are stepped transmissions, which can be divided into three types according to structure: mobile gear type, constant mesh gear type and planetary gear type. These gear transmissions have a base or a gear box, and the base or the gear box is provided with at least two shafts including an input shaft and an output shaft through bearings, and the shaft has a circular gear, which is formed from the input shaft to the output shaft The gear shifting of at least two gear circular gear mechanisms is realized. Some non-circular gear mechanisms with variable transmission ratio transmission are equipped with non-circular gears that mesh with each other on the driving shaft and driven shaft or a combination of non-circular gears tha...
