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 the advantage of many uniquenesses.Its most outstanding feature is: when transferring power, it can carry out power dividing; Meanwhile, its input shaft and output shaft have alignment, and namely output shaft and input shaft are all arranged on same main axis.So Planetary Gear Transmission has now been used by people to replace ordinary gear transmission, and as the retarder in various machine driven system, speed increaser and speed change gear.Especially those are wanted that cube is little, quality is little, compact structure and the high aeroengine of transmission efficiency, lifting transport, petrochemical industry and weapons etc. gear drive and need the gear drive of the vehicle such as automobile and tank of differential mechanism, Planetary Gear Transmission has obtained and has applied more and more widely.But because in most widely used 2K-H Gear Planet Transmission, planet carrier 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 constantly revolves round the sun along with planet carrier and does rotation around own axes simultaneously, spatial position is not fixed, moment changes, during pinpoint pressure lubrication, lubricant oil cannot aim at planet wheel the moment and planet wheel bearing carries out lubrication and cooling, it can only be cyclical intermission formula lubrication and cooling, lubrication next time could be accepted when planet carrier turns over several angle, can not cool by continuous lubrication when bearing on planet wheel is run up, be easy to that burn occurs damage.
Herringbone gear transmission not only has helical gear advantage, and can not adopt the shortcoming of large helix angle because axial force is excessive when can overcome Helical gear Transmission.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, have 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 Inside gear drive, is widely used in the fields such as Gear Planet Transmission.Because herringbone ring gear Gear Planet Transmission assembly problem cannot be solved, current Gear Planet Transmission field haves no alternative but to adopt straight-tooth or low pitch angle helical teeth ring gear, for major diameter herringbone ring gear, be limited to the restriction of equipment processing maximum machinable diameter, be difficult to processing especially, even if adopt super large machine tooling to go out all-in-one-piece herringbone ring gear be also difficult to the assembling of whole Gear Planet Transmission, 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, combined type herringbone ring gear at present more adopts two helical teeth overall ring gear combination connection to form, such integrated type major diameter ring gear still cannot be processed, integrated type diameter ring gear depends on shaping machine maximum machinable diameter, skinny device cannot be utilized to process large workpiece, give full play to the working ability of lathe.Integrated type gear ring, must integral replacing gear ring once occur that a tooth or a small amount of several tooth lost efficacy, at substantial financial resources, material resources.In addition, be difficult to when the combination of two helical teeth ring gears connects to ensure left-right rotary to two gear ring teeth directional centerings good, all there is left-right rotary to larger teeth directional error of centralization in whole gear ring each tooth of a week.
Also there is herringbone ring gear segment design technology at present, patent documentation [CN101793308A] discloses a kind of inventive method of herringbone gear planet gear speed reducer, key technology is segmentation herringbone ring gear, this technology solves the assembly problem of double helical tooth planetary transmission, also the production problem of major diameter ring gear is solved, the large diameter ring gear of little machine tooling can be utilized, technical important breakthrough really and innovation, but this segmentation herringbone ring gear adopts the method for radial and axial equal segmentation, axially left-handed divided with the dextrorotation gear teeth, Bolt Connection is adopted to combine again, certainly there is comparatively big error in such centering, particularly radial circumference is lean against punching on inclined-plane to pass through Bolt Connection during the connection of two tooth sections, on inclined-plane, machining hole is very difficult, particularly bad location, inclined hole location and inaccurate, hole especially easily trains off, the position in hole and accuracy to shape are all difficult to ensure, but also be processing shoulder hole, screw thread is reprocessed in endoporus, also setting sleeve is installed, how setting sleeve is pressed at deep hole bottom, setting sleeve installation question is also very difficult, common process and method cannot solve at all, even if be pressed into setting sleeve reluctantly, how to ensure that the position be pressed into is accurate, how to measure, how to ensure that the setting sleeve be pressed into is indeformable, inclined hole spatial position and narrow and small, enough spanner spaces are not had to carry out clamping bolt, the problem how bolt is tightened becomes a difficult problem, due to the restriction of punching spatial position, inclined-plane and structure, two both sides, tooth section inclined-planes respectively can only process a hole, large diameter ring gear is connected by means of only two Bolt Connection, huge hidden danger is all had from strength and stiffness, and this inclined-plane hole knockout destroys the integrity of gear ring both side surface, stress is caused to concentrate, and there will be and have a lot of metal acute angle, and it is sharp, easily cause that operator scratch etc. and cause security incident, the connection precision of two tooth sections of this technology is ensured by inclined hole, it can thus be appreciated that assembly precision when cannot ensure two tooth section incline configuration connections at all, bolt plays anastomosis, positioning action and limited.Gear is as precision drive part, very responsive to error, be difficult to when the single hop ring gear that separates in addition axially and Radial Combinations connects guarantee left-right rotary to two gear ring teeth directional centerings good, all there is left-right rotary to larger teeth directional error of centralization in whole gear ring each tooth of a week, and radial direction and circumferencial direction cannot accurately be located, larger axial force will be produced like this, affect transmission stability etc., thus lose the part advantage of herringbone tooth.And the Gear Planet Transmission principle that patent documentation [CN101793308A] is announced is prevailing 2K-H Gear Planet Transmission, the technological scheme adopted is that ring gear maintains static, planet carrier rotates, such planet wheel and planet wheel bearing not only do rotation around own axes, must rotate with planet carrier and revolve round the sun, bear huge centrifugal force like this, the as easy as rolling off a log inefficacy of planet wheel spring bearing; Because planet wheel and planet wheel bearing rotated with the planet carrier moment, do not fix in the position in space, moment changes, the method that pinpoint pressure so just cannot be adopted to lubricate carries out lubrication and cooling to planet wheel and planet wheel bearing, can only be periodic step lubrication, because bearing runs up, not have again the lubricant oil moment to cool, be easy to that bearing heating occurs burn out, planet wheel is also because of the various forms of gear failure of the lubrication bad easy generation of heat radiation.
In order to solve the technical bottleneck of double helical tooth planetary driven Design, processing and assembling, the present invention proposes that a kind of structure is simple, easy to process, dismounting and change is easy, and planet wheel and bearing thereof be not by centrifugal force, pinpoint pressure lubrication and cooling can be continued, the double helical tooth planetary transmission device of processing and assembly technology requirement can be met, the actual demand of enterprise can be met, fill up correlation technique blank, larger social benefit and economic benefit can be produced again.
