Enclose.
Refer to Fig. 1, a kind of double reduction device, including shell 1, in shell 1, be provided with power shaft 2, PTO drive disk axle 3 and
Planetary gearsets 4, the power of power shaft 2 drives to PTO drive disk axle 3 by planetary gearsets 4, is provided with clutch in housing 1
5 and brake 6, clutch 5 Guan Bi links with power shaft 2, and clutch 5 separates and disconnects with power shaft 2, brake 6 close make defeated
Entering axle 2 and planetary gear 4 groups linkage, brake 6 separates and makes power shaft 2 disconnect with planetary gearsets 4, and clutch 5 closes, braking
Device 6 separates, and power shaft 2 drives to PTO drive disk axle 3, brake after power is driven to planetary gearsets 4 by clutch 5
6 Guan Bis are braked, and clutch 5 separates, and make power shaft 2 drive to PTO drive disk axle by power by planetary gearsets 4
3。
It addition, clutch 5 is provided with clutch power axle 7, outside planetary gearsets 4, it is provided with power input disc axle 8, clutch
Device 5 closes, and brake 6 separates, and power shaft 2 input power to clutch 5, it is defeated that clutch power axle 78 outputs power to power
Drive planetary gear set 4 to export power after entering dish axle 8 and export power to PTO drive disk axle 3.
It addition, brake 6 Guan Bi is braked, clutch 5 separates, and power shaft 2 end is connected with sun gear 41, will be dynamic
Power drives PTO drive disk axle 3 to rotate output power by planetary gearsets 4 after being transferred to planetary gearsets 4.
It addition, planetary gearsets 4 include sun gear 41 and be located at outside sun gear 41 and be meshed with sun gear
Planetary gear 42.Planetary gear 42 is engaged on external toothing 43, external toothing 43 respectively with PTO drive disk axle 2 and power input disc
Axle 8 is meshed.
It addition, clutch 5 closes, brake 6 separates, and the rotating ratio of power shaft 2 and PTO drive disk axle 3 is 1:1, braking
Device 6 Guan Bi is braked, and clutch 5 separates, and the rotating ratio of power shaft 2 and PTO drive disk axle 3 is that 1:n, n are more than 1.
It addition, clutch 5 is located between casing 1 and planetary gearsets 4, clutch 5 and planetary gearsets are located in brake 6
Between 4.
It addition, clutch 5 is arranged on housing 1 by clutch connecting plate.
Double reduction implement body operation principle of the present invention is as follows: decelerator divides two kinds of speed ratio states:
During 1:1, the principle of transmission is, electromagnetic clutch energising Guan Bi, in running order, brake guaranties discharges, and is in work
Make state, so, just make the dish axle of power shaft and planetary gearsets one integral type of composition, make reductor be in 1:1 and export shape
State.
During 1:81, the principle of transmission is, electromagnetic clutch power-off discharges, and is in off working state, and brake power machine closes
Close braking, be in off working state, so since, the revolution of output shaft input passes through after planetary gearsets, slows down,
But, within the speed ratio that single-stage planetary deceleration maximum is estimated is 15, it is important to how to reach 1:81 by the planetary gearsets of single-stage
Speed ratio, key here is exactly, and planetary gearsets has added the external toothing of two few teeth differences, by fixing one of them external tooth
Circle, the rotating speed then allowing planetary reduction gear export does few teeth difference by the external toothing of another activity again and moves, produces again one group of speed
Ratio, two groups of long-pending output speed ratios being decelerator of speed ratio, so with one, just reach what single-stage planetary deceleration was not accomplished
Band, than scope, reaches the purpose that the volume of large speed ratio is little.
Being different from prior art, double reduction device of the present invention, it is possible to realize speed-changing ratio, switching mode is simple, structure
Stable, using effect is good
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every present invention of utilization says
Equivalent structure or equivalence flow process that bright book content is made convert, or are directly or indirectly used in other relevant technical field, all
In like manner it is included in the scope of patent protection of the present invention.
