Abstract
The invention relates to a speed reduction device, in particular to a speed reduction device of an electric excavator. The speed reduction device of the electric excavator solves the problem that as the installation position of a working platform of the electric excavator is limited by space, a lifting speed reduction device which is simple in structure and machining can not be placed. The speed reduction device of the electric excavator is simple in structure, reduces the transmission size, is suitable for the occasions with low speed, large torque and limited space while achieving the uniform load, and is easy to machine. The speed reduction device of the electric excavator comprises an input gear shaft, an upper straight gear, a uniform load herringbone gear shaft, a left edge helical gear, a right edge helical gear, an output lower herringbone gear shaft, an output upper herringbone gear shaft and a big gear ring. A herringbone gear slides axially on a spline shaft left and right to adjust the position of itself, so that loads of the upper herringbone gear shaft and the lower herringbone gear shaft are balanced. The loads of the double-output devices are balanced, the service life of the parts is prolonged, and the maintenance cost is lowered; the parts can be machined on an ordinary machine tool, and the machining cost is lowered.
Description
Technical field
The present invention relates to a kind of deceleration device, particularly relate to a kind of electric excavator deceleration device.
Background technology
Single motor dual output mode that electric excavator adopts, adopts the moment of differential planetary gear device autobalance dual output gear, and structure and processing are comparatively complicated, and cost is higher.Or adopt bi-motor dual output mode, realize all carrying by controlling bi-motor, but the difference of layout type due to each electric excavator, make it use limited.
Summary of the invention
The invention provides a kind of electric excavator deceleration device.The program solves cannot placing structure and the problem of processing fairly simple lifting deceleration device because of electric excavator working platform installation site limited space.Structure of the present invention is simple, reduces transmission size, makes it to be applicable to low-speed big and the occasion of limited space while can realizing all carrying, and is also easy to processing simultaneously.
Electric excavator deceleration device comprises input gear axle, top spur gear, all carries herringbone gear shaft, left side helical gear, the right helical gear, exports bottom herringbone gear shaft, exports top herringbone gear shaft, bull gear.
Described input gear axle and described top spur gear are one-level Spur Gear Driving, described top spur gear and the described herringbone gear shaft that all carries pass through splined, the described herringbone gear shaft that all carries engages with described left side helical gear and described the right helical gear simultaneously, described left side helical gear and described the right helical gear pass through splined with described output bottom herringbone gear shaft and described output top herringbone gear shaft respectively, described output bottom herringbone gear shaft is identical with the number of teeth of described output top herringbone gear shaft, and engage with described bull gear simultaneously, the two ends of each axle are arranged on bearing support by bearing, the described bearing inner race tight fit of all carrying herringbone gear shaft and all carrying herringbone gear shaft two ends, can jointly do axial slip.
Preferably, described all carrying between the bearing inner race at herringbone gear shaft two ends and bearing outer ring has roller.
Preferably, described spur gear adopts standard spur gear, the herringbone bear that described double helical tooth all carries on herringbone gear shaft adopts standard herringbone bear, described dextrorotation helical gear adopts helical gear, described left-hand helical gear adopts helical gear, described output bottom herringbone gear shaft adopts standard herringbone gear shaft, described output top herringbone gear shaft adopts standard herringbone gear shaft, described bull gear adopts standard herringbone bear, adopt common standard component, common factory just can process, low processing cost.

Accompanying drawing explanation
Fig. 1 is single motor dual output deceleration device.
The axially loaded figure of Fig. 2 herringbone bear of the present invention, F1 are left side helical gears and all carry the axial force produced when herringbone gear shaft engages, and F2 is the right helical gear and all carry herringbone gear shaft
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, electric excavator working platform installation site limited space, making to promote the transmission size of deceleration device must be little as much as possible when meeting the demands.
Adopt single motor dual output mode, slid axially by herringbone gear shaft realizes all carrying simultaneously, reduces the modulus of gear, makes whole mechanism structure compact, simple and reliable.Its structure--external impetus is inputted by input gear axle 6, described input gear axle 6 is one-level Spur Gear Driving with top spur gear 4, described top spur gear 4 with all carry herringbone gear shaft 5 and pass through splined, the described herringbone gear shaft 5 that all carries engages with left side helical gear 7 and the right helical gear 8 simultaneously
Described bearing inner race 11 tight fit of all carrying herringbone gear shaft 5 and all carrying herringbone gear shaft two ends, can do axial slip jointly, contrary all the time with the axial force produced during its engagement.
Described left side helical gear 7 and described the right helical gear 8 are respectively with output bottom herringbone gear shaft 3 with export top herringbone gear shaft 2 and pass through splined, described output bottom herringbone gear shaft 3 is identical with the number of teeth of described output top herringbone gear shaft 2, and engages with bull gear 1 simultaneously.The two ends of each axle are arranged on bearing support by bearing.
The described herringbone gear shaft 5 that all carries can do axial slip jointly with the bearing inner race 11 all carrying herringbone gear shaft 5 two ends.
The foozle of each gear cause described output top herringbone gear shaft 2 and described output bottom herringbone gear shaft 3 stand under load unbalanced, reflect that described left side helical gear 7, described the right helical gear 8 all carry with described the difference that herringbone gear shaft 5 engages axial force, this just makes the described herringbone gear shaft 5 that all carries constantly adjust its position, thus makes the stand under load of described output top herringbone gear shaft 2 and described output bottom herringbone gear shaft 3 balanced.
Described all carrying between the bearing inner race 11 at herringbone gear shaft 5 two ends and bearing outer ring 9 has roller 10.
