The purpose of this utility model is finished by following technical solution, it mainly is made of main reduction gear, diff, semiaxis and wheel reduction gear, and described wheel reduction gear includes sun wheel shaft, adapter sleeve, satellite gear, internally toothed annulus, planetary wheel carrier, wheel hub, gear ring support; Described satellite gear is installed on the planet wheel spindle by needle roller, planet wheel spindle and wheel carrier are cast in together and constitute the cantilevered planetary wheel carrier, sun wheel shaft links together by the form and the semiaxis of adapter sleeve with spline, and internally toothed annulus relies on gear ring to support with wheel limit pivot shaft and fixes; Wheel hub rely on tapered roller bearing and with wheel limit pivot shaft and gear ring support fixation.
The housing of described wheel reduction gear and planetary wheel carrier individual cast, and wheel reduction gear housing and wheel hub cast solid, planetary wheel carrier and wheel hub pass through independently bolted connection; Periphery design at wheel hub has the flange that wheel is installed, and boring is installed wheel by rim bolt on the flange.
The utility model has adopted cantilevered planetary wheel carrier, changed the material of planetary wheel carrier, planet wheel spindle and wheel carrier are cast in together, have changed planetary wheel carrier and wheel hub connection location, compare traditional drive axle, greatly reduce part casting difficulty, assembling is easier, reduce the manufacturing cost of drive axle, improved production efficiency, changed the connection mode of semiaxis and sun wheel, obtain bigger hub reduction ratio, for drill carriage provides a kind of simple and practical novel drive axle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a wheel reduction gear structural representation described in the utility model.
The specific embodiment
In the accompanying drawing: 1, main reduction gear, 2, diff, 3, semiaxis, 4, wheel reduction gear, 5, wheel limit pivot shaft, 6, tapered roller bearing, 7, brake disc, 8, the brake disc bolt, 9, wheel hub, 10, tapered roller bearing, 11, gear ring supports, 12, internally toothed annulus, 13, bolt, 14, planetary wheel carrier, 15, needle roller, 16, satellite gear, 17, sun wheel shaft, 18, adapter sleeve.
The utility model mainly is made of main reduction gear 1, diff 2, semiaxis 3 and wheel reduction gear 4, and wherein said wheel reduction gear mainly is made of sun wheel shaft, satellite gear, internally toothed annulus, planetary wheel carrier, wheel hub, gear ring support, bearing etc.Sun wheel shaft is installed in semiaxis one end by spline, satellite gear is installed on the planet wheel spindle by needle bearing, has removed the planet wheel spindle carriage on original planetary wheel carrier, and planet wheel spindle and planetary wheel carrier are cast as integral body, constitute the cantilevered planetary wheel carrier, its material also becomes ZG40Cr by QT450-10.Originally wheel reduction gear housing and planetary wheel carrier cast solid, and link together by bolt and wheel hub, and this bolt effect of connection wheel of having held concurrently, design after the improvement is wheel reduction gear housing and planetary wheel carrier individual cast, and wheel reduction gear housing and wheel hub cast solid, in its periphery design the flange that wheel is installed is arranged, boring is installed wheel by rim bolt on the flange.Wheel hub and cantilevered planetary wheel carrier constitute the shell of wheel reduction gear together.
Be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the running part of novel drill carriage drive axle described in the utility model mainly is made of main reduction gear 1, diff 2, semiaxis 3 and wheel reduction gear 4, and the utility model mainly is that the structure of wheel reduction gear 4 is carried out certain improvement.
As shown in Figure 2, wheel reduction gear described in the utility model mainly is made of sun wheel shaft 17, adapter sleeve 18, satellite gear 16, internally toothed annulus 12, planetary wheel carrier 14, wheel hub 9, gear ring support 11 etc.Satellite gear 16 is installed on the cantilevered planetary wheel carrier 14 by needle roller 15, and its material also becomes ZG40Cr by QT450-10.Sun wheel shaft 17 is installed in an end of semiaxis 3 by adapter sleeve 18, and it is 11 fixing with wheel limit pivot shaft 5 that internally toothed annulus 12 relies on gear rings to support.Wheel hub 9 relies on tapered roller bearings 6 and 10 to support 11 with wheel limit pivot shaft 5 and gear ring and fixes.Wheel reduction gear housing and planetary wheel carrier 14 individual casts, and wheel reduction gear housing and wheel hub 9 casts solid, planetary wheel carrier 14 and wheel hub 9 are connected by bolt 13 independently.In wheel hub 9 periphery designs the flange that wheel is installed is arranged, boring is installed wheel by rim bolt on the flange.
The moment of torsion that sun wheel shaft 17 on the wheel reduction gear passes over semiaxis 3 passes to satellite gear 16, satellite gear 16 passes to moment of torsion on the wheel limit housing of planetary wheel carrier 14 and wheel hub 9 formations by planet wheel spindle again, on the flange of wheel limit housing periphery rim bolt is housed, moment of torsion finally passes to wheel by rim bolt.
Planet wheel spindle on the wheel reduction gear originally is to rely on carriage to be installed on the planetary wheel carrier, has the planetary wheel carrier complex structure of carriage, and the casting difficulty is big, and internal operation is difficult for, thereby has increased the manufacturing cost of part.Original in addition planetary wheel carrier is connected at the rim bolt place with wheel hub 9, and planetary wheel carrier becomes the housing on wheel limit.The carriage on the planetary wheel carrier has been removed in present later-model design, and planet wheel spindle and wheel carrier are cast as one, constitutes cantilevered planetary wheel carrier 14.Planetary wheel carrier 14 has also been done change with the connection location of wheel hub 9, by independently bolt 13 connections.Wheel hub 9 is cast with the wheel reduction gear housing and is in the same place, and the flange on wheel hub 9 peripheries is equipped with rim bolt, is used for installing wheel.
Such improvement design simplification the structure of wheel reduction gear, make that wheel limit planetary wheel carrier casting difficulty reduces, intensity increases.The inner structure compactness of drive axle, easy, the productive costs of assembling reduce and efficient improves.For a series of drill carriages provide a kind of simple and practical novel drive axle.
