Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
Three-gear manual speed changer as shown in Figure 1 and Figure 2, comprises input shaft 1, output shaft 2 and jack shaft 3, and input shaft 1 and output shaft 2 coaxial line are arranged, jack shaft 3 is arranged in parallel in input shaft and output shaft side.Wherein, coaxially in one end of this input shaft be provided with attachment hole, one end of output shaft is rotating to be inserted in the attachment hole of input shaft.
Input shaft, output shaft and jack shaft are respectively equipped with input gear 4, output gear 5 and intermediate gear 6, the end face of input gear 4 and output gear 5 near.
Input shaft 1 and output shaft 2 are arranged with the first gear ring 7, jack shaft 3 is arranged with the second gear ring 8 and the 3rd gear ring 9.Fig. 3 is the schematic diagram of the first gear ring, and described second is identical with the structure of the first gear ring with the 3rd gear ring, and three gear rings all have internal tooth and external tooth.
First gear ring 7 can drive by the first shift fork 10 jointing place moved axially to input gear 4 and output gear 5, engaged with input gear and output gear by its internal tooth simultaneously, or move axially on the gear of in input gear and output gear, engaged with input gear 4 or output gear 5 by its internal tooth, and the external tooth of this first gear ring often engages with the intermediate gear 6 on jack shaft.
On described jack shaft 3 second and the 3rd gear ring lay respectively at right side and the left side of the axis of the first gear ring, and second and the 3rd gear ring often engage with output gear 4 and input gear 5 respectively, wherein, second gear ring 8 can be driven inwardly to move axially by the second shift fork 11 and be inserted in intermediate gear 6, engaged with intermediate gear by the internal tooth of the second gear ring 8, or driven outwards to move axially by the second shift fork 11 and depart from intermediate gear empty set on jack shaft, 3rd gear ring 9 can be driven inwardly to move axially by the 3rd shift fork 12 and be inserted in intermediate gear, engaged with intermediate gear 6 by the internal tooth of the 3rd gear ring 9, or driven outwards to move axially by the 3rd shift fork and depart from intermediate gear empty set on jack shaft.
Can realize three kinds of transforming gears by above-mentioned speed changer, three kinds of gears are respectively top gear, middle gear and bottom gear.Its working principle is as follows:
Middle gear: now the first gear ring 7 is positioned at the jointing place of input gear 4 and output gear 5, is engaged with input gear and output gear by its internal tooth, input shaft 1 and output shaft 2 synchronous axial system simultaneously.Second gear ring 8 and the 3rd gear ring 9 all depart from empty set on jack shaft 3 with intermediate gear 6 simultaneously.Therefore during intervening gears, the moment of torsion on input shaft acts directly on output shaft, complete direct driving force and export.
Top gear: now the first gear ring 7 is driven by the first shift fork 10 and moves axially left, the internal tooth of the first gear ring only engages with input gear 4, and external tooth engages with intermediate gear 6.Second gear ring 8 is driven to be moved to the left by the second shift fork 11 and is inserted in intermediate gear 6 simultaneously, and the internal tooth of the second gear ring engages with intermediate gear, and external tooth engages with output gear 5.The 3rd gear ring 9 is kept to depart from empty set at jack shaft with intermediate gear 6.Therefore, during high gear, the power on input shaft 1 is passed on intermediate gear 6 by the first gear ring 7, is then passed on output shaft 2 through the second gear ring 8, just completes high rotating speed and exports.
Bottom gear: now the first gear ring 7 is driven by the first shift fork 10 and moves axially to the right, the internal tooth of the first gear ring only engages with output gear 5, and external tooth engages with intermediate gear 6.3rd gear ring 9 is driven to move right by the 3rd shift fork 12 and is inserted in intermediate gear 6 simultaneously, and the internal tooth of the 3rd gear ring 9 engages with intermediate gear, and external tooth engages with input gear 4.The second gear ring 8 is kept to depart from empty set at jack shaft with intermediate gear.Therefore, during low gear, the power on input shaft to be passed on intermediate gear 6 by the 3rd gear ring 9, is then passed on output shaft 2 through the first gear ring 7, just completes the slow-speed of revolution and exports.
