Abstract
The utility model relates to a herringbone gear twin countershaft transmission, which comprises a casing, wherein the casing is provided with a first shaft hole, and two opposite countershaft holes are arranged in the casing and located at two sides of the first shaft hole. The first shaft hole is equipped with a first shaft by a bearing assembly. A herringbone gear is arranged at an inner end of the first shaft, a second shaft hole is disposed at the center of an inner end of the herringbone gear, and the second shaft hole is equipped with a second shaft by a bearing assembly. The countershaft holes at the two sides are provided with countershafts respectively by the bearing assemblies, and the countershafts are provided with helical gears at end portions to which the herringbone gear is adjacent, wherein the helical gear of one of the countershafts is engaged with right-hand teeth corresponding to the herringbone gear and the helical gear of the other countershaft is engaged with left-hand teeth corresponding to the herringbone gear. The herringbone gear twin countershaft transmission has compact structure and reliable performance, can distinctly reduce the weight and the axial dimensions of a transmission, and thus maximum transmission power and transmission torque are improved, thereby expanding application scope.
Description
Technical field
The utility model relates to a kind of transmission device, relates in particular to a kind of herringbone gear twin countershaft transmission that is applied to truck.
Background technique
Along with the fast development of automotive industry, the variation of vehicle, personalized own through becoming the trend of development of automobile.And the design of speed changer be link important in the Automobile Design it.It is to be used for changing motor car engine to pass to torque and rotating speed on the driving wheel for a speed changer, and purpose is under the various road conditions of going, and makes automobile obtain different tractive force and travelling speed, and motor is worked in the scope under best operating mode.At present, for the large-tonnage truck, vehicle needs that the bearing capacity of speed changer is big, gear is many, and the advantage of twin countershaft transmission has obtained effective performance here.But two intermediate gearboxs of this type mostly are the driving of parallel axes of adopting spur gear wheel, adopt spur gear wheel to exist bearing capacity poor, short and impact of life-span, vibration, the defective that noise is big.
The model utility content
In order to overcome the above-mentioned shortcoming of existing technology, the utility model provides a kind of truck bearing capacity that can make stronger, and transmission is more steady, and volume is littler, weight is lighter, cost herringbone gear twin countershaft transmission lower and simple in structure.
The utility model solves the technological method that its technical problem adopted: a kind of herringbone gear twin countershaft transmission, and comprise casing, in this casing, be provided with an axis hole, on the said casing in the both sides of an axis hole, be provided with intermediate shaft hole respectively relatively.A said axis hole is equipped with one through bearing unit, is provided with herringbone gear a inner, is provided with two axis holes at the inner center of herringbone gear, and this two axis hole is equipped with two through bearing unit.Through bearing unit jack shaft is housed respectively on the intermediate shaft hole on said both sides, the end adjacent with above-mentioned herringbone gear at jack shaft is equipped with cylindric spiral gear, and wherein the cylindric spiral gear of a jack shaft is meshed with the corresponding right-hand teeth of above-mentioned herringbone gear; Wherein the cylindric spiral gear of another jack shaft is meshed with the corresponding left-hand teeth of above-mentioned herringbone gear.
The beneficial effect of the utility model is: herringbone gear has advantages such as bearing capacity height, stable drive and thrust load are little, in the transmission system of heavy machinery, is widely used.The transmission application herringbone gear between one of twin countershaft transmission and the jack shaft and the structure of cylindric spiral gear, it is poor to have solved the spur gear wheel Transmission bearing, short and impact of life-span, vibration, the problem that noise is big.The utlity model has compact structure, reliable, and can reduce the quality and the axial dimension of speed changer significantly, utilize this advantage, can improve the maximum delivered power and the moment of torsion of speed changer, enlarge its using scope.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-casing, axis hole of 2-, 3-intermediate shaft hole, 4-bearing unit, one of 5-, 6-herringbone gear, 7-two axis holes, two of 8-, 9-jack shaft, 10-cylindric spiral gear.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Referring to Fig. 1; A kind of herringbone gear twin countershaft transmission; In the casing 1 of speed changer, be equipped with one 5 through an axis hole 2 and bearing unit 4; One 5 inner driving gear is herringbone gear 6 structures, is provided with two axis holes 7 at the center of the end face of herringbone gear 6, and the end that speed changer is two 8 is sleeved in described two axis holes 7 through bearing unit 4; With the casing 1 of herringbone gear 6 adjacent both sides speed changers on through intermediate shaft hole 3 and bearing unit 4 jack shaft 9 is installed respectively, be separately installed with in the end of two jack shafts 9 and the corresponding cylindric spiral gear 10 of herringbone gear 6 left right-hand teeths.By the driving mechanism that herringbone gear 6 and cylindric spiral gear 10 are formed, theory and practice proves that herringbone gear 6 has advantages such as bearing capacity height, stable drive and thrust load are little, in the transmission system of heavy machinery, is widely used.The transmission application herringbone gear 6 between one 5 of twin countershaft transmission and the jack shaft 9 and the structure of cylindric spiral gear 10; It is poor to have solved existing technology truck twin countershaft transmission spur gear wheel Transmission bearing, short and impact of life-span, vibration, the problem that noise is big.The utlity model has compact structure, reliable, and can reduce the quality and the axial dimension of speed changer significantly, utilize this advantage, can improve the maximum delivered power and the moment of torsion of speed changer, enlarge its using scope.But in practice, receive factor affecting such as road conditions, operating mode and load, the herringbone gear twin countershaft transmission is more suitable for China's actual conditions, the domestic user's that is bound to receive deeply favor.
