Embodiment Construction
[0019] The accompanying drawings disclose the specific structures of the embodiments of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Depend on figure 1 It can be seen that the present invention includes a box body and a planetary gear train. The box body is composed of a front box body 1, a rear box body 2, and a same internal ring gear 3, and the same inner body ring gear 3 is located between the front box body 1 and the rear box body 2. There are two sets of planetary gear trains with different transmission ratios on the planet carrier 4 and the sun gear shaft 6, wherein: two sets of sun gears 7 are supported on the sun gear shaft 6 of the same stage through bearings 8, and non-stop gears are set between the two sets of sun gears 7. Shifting mechanism (I in the figure); the inner ring gears of the two sets of planetary gear trains are assembled on the same inner rin...

The invention relates to a no-shutdown gear-shifting planetary gear train in a gear box. The no-shutdown gear-shifting planetary gear train comprises a box body and a planetary gear train, the box body is composed of a front box body, a rear box body and an inner tooth ring, and the inner tooth ring is located between the front box body and the rear box body. The no-shutdown gear-shifting planetary gear train is characterized in that an identical stage of planet carrier and a sun wheel axle are provided with two groups of planetary gear trains different in transmission ratios, wherein two groups of sun wheels are supported on the identical stage of sun wheel axle through bearings, and a no-shutdown gear-shifting mechanism is arranged between the two groups of sun wheels. Inner tooth rings of the two groups of planetary gear trains are gathered on an identical body inner tooth ring, 3-5 planetary wheel axles are evenly distributed on the planet carrier, and two planetary gears different in transmission ratios are installed on every planetary wheel axle through bearings.
Description
technical field [0001] The invention relates to a non-stop shifting planetary gear train in a gear box, which can be applied to special occasions where shifting after stopping is not allowed, and can also be applied to general occasions where shifting gears after stopping is not allowed. Background technique [0002] In economical production, the production actuators on the production line sometimes need to obtain two different operating speeds. In many cases, we need to shift gears to complete such tasks. Although the current non-stop gear shifting technology is relatively mature, the clutch is generally inseparable from the system, and requires the close cooperation of the operator. The mechanism is more complicated and requires higher requirements for the operator. Due to the particularity of the structure of the planetary gear train, the gear change can only be realized after the planetary gearbox is stopped. How to solve the non-stop gear shifting of the planetary gear...
