Description
Technical field
The present invention relates to Gear Planet Transmission technical field, particularly relate to a kind of double helical tooth planetary transmission device.
Background technique
Planetary Gear Transmission is compared with ordinary gear transmission, and it has advantages of many uniquenesses.Its outstanding feature is: in the time of transferring power, it can carry out power dividing; Meanwhile, its input shaft and output shaft have alignment, and output shaft and input shaft are all arranged on same main axis.So Planetary Gear Transmission is now used for replacing ordinary gear transmission by people, and as the retarder in various machine driven systems, speed increaser and speed change gear.Especially for those want that cube is little, quality is little, the gear drive of compact structure and high aeroengine, lifting transportation, petrochemical industry and the weapons etc. of transmission efficiency and need the gear drive of the vehicle such as automobile and tank of differential mechanism, Planetary Gear Transmission has obtained application more and more widely.But because planet carrier in most widely used 2K-H Gear Planet Transmission constantly rotates, planet wheel and planet wheel bearing rotate with planet carrier, bear very large centrifugal force, be easy to cause bearing failure, planet wheel is along with constantly revolution and do rotation around self axis of planet carrier simultaneously, spatial position is unfixing, moment changes, fixed point when pressure lubrication lubricant oil cannot aim at planet wheel the moment and planet wheel bearing is lubricated with cooling, it can only be cyclical intermission formula lubrication and cooling, in the time that turning over several angle, planet carrier could accept next time lubricated, can not continuous lubrication while running up for the bearing on planet wheel cooling, being easy to occur burn damages.
Herringbone gear transmission not only has helical gear advantage, and can overcome Helical gear Transmission time because of the excessive shortcoming that can not adopt large helix angle of axial force.Herringbone tooth engagement has at the whole contact ratio of large helix angle lower gear large, do not produce axial force, bearing capacity is high, and long service life, reliability are high, stable drive and the advantage such as vibration noise is little, has been widely used in the power transmission field of the high speed load-carryings such as naval vessel, aviation, metallurgy, mine.
Double helical tooth planetary transmission combines the advantage of Gear Planet Transmission and herringbone gear transmission, but double helical tooth planetary transmission assembling difficulty, conventional double helical tooth planetary transmission almost cannot be assembled, and is the bottleneck of double helical tooth planetary drive technology development.Ring gear, as one of requisite driving component of interior engagement driving, is widely used in the fields such as Gear Planet Transmission.Because solving herringbone ring gear Gear Planet Transmission assembly problem, straight-tooth or low pitch angle helical teeth ring gear are haveed no alternative but to adopt in Gear Planet Transmission field at present, for major diameter herringbone ring gear, be limited to the restriction of equipment processing maximum machinable diameter, be difficult to especially processing, also be difficult to whole Gear Planet Transmission assembling even if adopt super large machine tooling to go out all-in-one-piece herringbone ring gear, sun gear, planet wheel, ring gear all adopt integral herringbone gear to assemble.Major diameter herringbone ring gear segmentation processing is the inexorable trend of large-scale herringbone gear Gear Planet Transmission development, two helical teeth entirety ring gears of combined type herringbone ring gear many employings at present combine to connect and form, integrated type major diameter ring gear still cannot be processed like this, integrated type diameter ring gear depends on shaping machine maximum machinable diameter, cannot utilize skinny device to process large workpiece, give full play to the working ability of lathe.Once there is tooth or a small amount of several tooth and lost efficacy in integrated type gear ring, must integral replacing gear ring, expend a large amount of financial resources, material resources.In addition, the combination of two helical teeth ring gears while connection, be difficult to guarantee left-right rotary to two gear ring teeth directional centerings good, whole gear ring each tooth of a week all exists left-right rotary to larger teeth directional error of centralization.
