Description
Technical field
The present invention relates to mine excavator, particularly a kind of driving speed reducer of mine excavator main drive gear.
Background technique
As main transmission section claimed structure compactness, the bearing capacity height of mine excavator heart, be convenient to installation and maintenance.The lifting of excavator in the past, pushing, revolution, walking main transmission speed reducer all adopt cylindrical gears structure commonly used.Figure 1 shows that the driving speed reducer of cylindrical gears parallel axes structure, input gear shaft 1 and gear 2 engagements, by the countershaft-gear axle engagement driving gear 3 parallel with input shaft, gear 3 driven gear axles 4 drive afterbody gear shaft 5 by engaging gear.
The driving speed reducer of prior art, because speed ratio is bigger, the restriction in space in addition makes that the safety coefficient of this reducer gear intensity is little; Because driving speed reducer connects by jaw brake with track frame, braking moment is big, and braking effect is poor; Because afterbody gear shaft 5 is installed on track frame inside, must unload speed reducer earlier when changing break, maintenance is inconvenience comparatively.
The walking of large excavator and swirl gear require that higher bearing capacity and run stability are arranged, if adopt traditional cylindrical gears structure speed reducer, are satisfying under the condition of installing space, and bearing capacity is lower, does not satisfy the usage requirement of main frame.
Summary of the invention
Purpose of the present invention is intended to overcome the shortcoming of prior art, and a kind of mine excavator walking planetary speed reducer is provided, and the driving speed reducer bearing capacity that solves prior art is low, the problem of inconvenient maintenance.
The present invention is achieved by the following technical solutions:
A kind of mine excavator walking planetary speed reducer, comprise: first order input gear shaft, it is characterized in that: described first order input gear shaft and gear engagement, gear and second level solar shaft adopt splined, second level solar shaft drives second level planet wheel and the engagement of second level ring gear, second level solar shaft drives second level planet carrier unitary rotation by second level planet wheel and being connected of bearing pin (), second level planet carrier is tooth-like the connection with third level solar shaft, third level solar shaft drives third level planet wheel and the engagement of third level ring gear, third level solar shaft drives third level planet carrier by being connected of third level planet wheel and bearing pin (two) and constitutes third level epicyclic transmission mechanism, passes through the internal spline output torque by third level planet carrier at last.
The present invention compared with prior art has following outstanding advantage and remarkable result:
First order input shaft of the present invention adopts the parallel axes structure, and the input output disalignment can make the input motor arranged in dislocation of left and right driving speed reducer, is convenient to installation and maintenance.Second level solar shaft is whole to float, and effectively realizes all carrying of driving mechanism, strengthens anti-impact force.Overcome the low shortcoming of original parallel axes reducer gear intensity, and the live axle of track frame connects directly with driving speed reducer by spline, be convenient to installation and maintenance.
Description of drawings
Fig. 1 is a prior art parallel axes driving speed reducer structural drawing;
Fig. 2 is a walking planetary speed reducer structural drawing.
The invention will be further described by preferred embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 2, a kind of mine excavator walking planetary speed reducer, comprise: first order input gear shaft 1, described first order input gear shaft 1 and gear 6 engagements, gear 6 adopts splined with second level solar shaft 7, second level solar shaft 7 drives second level planet wheel 8 and 9 engagements of second level ring gear, second level solar shaft 7 drives second level planet carrier 11 unitary rotation by second level planet wheel 8 and being connected of bearing pin () 10, second level planet carrier 11 is tooth-like the connection with third level solar shaft 12, third level solar shaft 12 drives third level planet wheel 13 and 14 engagements of third level ring gear, third level solar shaft 12 constitutes third level epicyclic transmission mechanism by driving third level planet carrier 16 being connected of third level planet wheel 13 and bearing pin (two) 15, passes through the internal spline output torque by third level planet carrier 16 at last.
The second level and the third level are planetary structure in the structure of the present invention, and wherein third level Gear Planet Transmission is whole floating.This relocation mechanism does not have the bearing positioning supports, realizes the location by gear engagement and jacking block 17, effectively reduces impulsive load, realizes all carrying of driving mechanism.Third level planet carrier 16 is for to have only a side that the single support structure of bearings is arranged, and opposite side there is no bearings with planet wheel do rotation motion.This kind structure can improve the bearing capacity of mechanism on the one hand, and the two-stage planetary structure can be realized bigger transmission speed ratio in limited space simultaneously, improves transmission efficiency.
