Specific embodiment
The present invention is described in further details with reference to embodiments (attached drawing):
As shown in Figure 1, 2, compact type large power pressure break planetary reduction gear of the invention includes cabinet and lubricating arrangement 27, passes through axis
It holds 2 and is supported on input shaft 1 and the parallel stage transmission successively driven by input shaft 1, planetary stage transmission, output flower on cabinet
Key set 18；The parallel stage transmission uses large helix angle Combined herringbone gear structure, it includes driving gear and driven tooth
Wheel, the driving gear are by being arranged in parallel, outside oppositely oriented left and right active by connector and 1 Joint of input shaft
The combination gear ring that gear ring 5,6 is constituted, the driven gear are parallel the setting by passing through connector and 11 Joint of Driven hub
It sets, the combination gear ring that oppositely oriented left and right driven outer gear ring 12,13 is constituted, the Driven hub 11 is supported by bearing 8
On cabinet, and it is located at the oppositely oriented of driving gear and driven gear the same side outer gear ring；The planetary stage transmission is using big
Helical angle large pressure angle herringbone toothing, including sun gear 9, planetary gear 19, planet wheel spindle 21, ring gear, planet carrier 16；It is described
Ring gear is separate structure, and the left and right ring gear 24,25 by being arranged in parallel, oppositely oriented forms, and passes through bolt 23 and ladder
Combination pin 15 is fixed together with left, middle cabinet 22,14；The planetary gear 19 is expert at by bearing 20 and the fixation of planet wheel spindle 21
In carrier 16；The planet carrier 16 and sun gear 9 are floating structure；Sun gear 9 and planetary gear 19 positioned at the same side revolve
To on the contrary, the same side planetary gear 19 is identical as ring gear 24,25 rotation directions；19 numbers of planetary gear are more than or equal to three；Sun gear 9 is logical
Spline 10 is crossed to combine with Driven hub 11；Output spline housing 18 is combined with planet carrier spline 17.
