具体实施时:如图2所示,第一花键齿1包括第一基座10、分别凸设在第一基座10两侧端的外花键部12和定位凸轴13。其中,第一基座10呈圆柱状,外花键部12和定位凸轴13分别自第一基座10两侧的中部向外凸出设置。 In specific implementation: as shown in FIG. 2 , the first spline tooth 1 includes a first base 10 , external spline portions 12 protruding from both sides of the first base 10 and positioning protruding shafts 13 . Wherein, the first base 10 is cylindrical, and the external spline portion 12 and the positioning protruding shaft 13 protrude outward from the middle of both sides of the first base 10 .
外花键部12设在如图2所示的左侧,其外径小于第一基座10的外径,外花键部12用于连接第一传动轴8(图8所示)。实施时,第一传动轴8上具有与外花键部12尺寸相适配的花键。装配后,第一传动轴8可与第一花键齿1同轴转动。这样,当第一传动轴8受力转动时,第一花键齿1将可与第一传动轴8联动。本实施例中,第一基座10的一侧端面1a上等距开设四个安装槽11,该安装槽11呈立方状,如图3所示。 The outer spline part 12 is arranged on the left side as shown in FIG. 2 , and its outer diameter is smaller than that of the first base 10 . The outer spline part 12 is used for connecting the first transmission shaft 8 (shown in FIG. 8 ). In practice, the first transmission shaft 8 has splines matching the size of the external spline portion 12 . After assembly, the first transmission shaft 8 can rotate coaxially with the first spline tooth 1 . In this way, when the first transmission shaft 8 is rotated under force, the first spline teeth 1 can be linked with the first transmission shaft 8 . In this embodiment, four mounting grooves 11 are equally spaced on one end surface 1 a of the first base 10 , and the mounting grooves 11 are in a cubic shape, as shown in FIG. 3 .
定位凸轴13设在如图2所示的右侧,其外径小于外花键部12的外径,定位凸轴13用于连接第二花键齿2,具体装配方式下述说明。 The positioning protruding shaft 13 is arranged on the right side as shown in FIG. 2 , and its outer diameter is smaller than that of the outer spline part 12. The positioning protruding shaft 13 is used to connect the second spline teeth 2. The specific assembly method is described below.
进一步的,如图4所示,第二花键齿2包括第二基座20、第二基座20的一侧内凹设有与第一基座10的定位凸轴13相适配的定位腔22,第二基座20的相对另一侧设有外花键部23。其中,第二基座20呈圆柱状,外花键部23自第二基座20如图4所示右侧的中部向外凸出设置,定位腔22内凹设在第二基座20如图4所示左侧的中部。 Further, as shown in FIG. 4 , the second spline tooth 2 includes a second base 20 , and one side of the second base 20 is concavely provided with a positioning position that matches the positioning protruding shaft 13 of the first base 10 . The cavity 22 and the opposite side of the second base 20 are provided with an external spline portion 23 . Wherein, the second base 20 is cylindrical, and the external spline portion 23 protrudes outward from the middle part of the second base 20 as shown in FIG. Figure 4 shows the middle on the left.
外花键部23用以连接第二传动轴9(如图8所示)。具体实施时,第二传动轴9上具有与外花键部23尺寸相适配的花键。装配后,第二传动轴9可与第二传动轴9同轴转动。这样,当第一花键齿1与第一传动轴8联动时,由于第一花键齿1和第二花键齿2相连接,便可将扭转力传至第二传动轴9上。 The external spline part 23 is used for connecting the second transmission shaft 9 (as shown in FIG. 8 ). During specific implementation, the second transmission shaft 9 has splines matching the size of the external spline portion 23 . After assembly, the second transmission shaft 9 can rotate coaxially with the second transmission shaft 9 . In this way, when the first spline teeth 1 are linked with the first transmission shaft 8 , since the first spline teeth 1 and the second spline teeth 2 are connected, the torsional force can be transmitted to the second transmission shaft 9 .
第一花键齿1和第二花键齿2通过如下结构进行装配:第二基座20的一侧端面2a上开设形状结构与第一花键齿1上四个安装槽11结构形状相同的四个安装槽21,如图5所示。当第二花键齿2的端面2a朝向第一花键齿1的端面1a装配时,定位凸轴13适配插置在定位腔22中。此时,第一花键齿1的四个安装槽11能够分别与第二花键齿2的四个安装槽21对接形成一用以放置传动件3的空腔(安装槽11、21)。 The first spline tooth 1 and the second spline tooth 2 are assembled through the following structure: the shape and structure of the first side end surface 2a of the second base 20 is the same as that of the four installation grooves 11 on the first spline tooth 1. Four mounting grooves 21 are shown in FIG. 5 . When the end surface 2 a of the second spline tooth 2 is assembled towards the end surface 1 a of the first spline tooth 1 , the positioning protruding shaft 13 is fitted and inserted in the positioning cavity 22 . At this time, the four installation grooves 11 of the first spline tooth 1 can be respectively butted with the four installation grooves 21 of the second spline tooth 2 to form a cavity (installation grooves 11 , 21 ) for placing the transmission member 3 .
优选的,传动件3为一圆柱销。 Preferably, the transmission member 3 is a cylindrical pin.
优选的,定位凸轴13上设有用以在相对于第一花键齿1的轴线方向上对第二花键齿2进行限位的卡箍5。参见图6,卡箍5为具有一开口的卡持环,具体实施时,可以在定位凸轴13的端面上开设一槽缝(图未示),当定位凸轴13适配插置在定位腔22中后,便可将卡箍5装在该槽缝中。这样,卡箍5便能够阻止两花键齿1、2在轴线方向分离,实现两花键齿1、2的可同轴移动。 Preferably, the positioning protruding shaft 13 is provided with a clamp 5 for limiting the position of the second spline tooth 2 in the axial direction relative to the first spline tooth 1 . Referring to Fig. 6, the clamp 5 is a clamping ring with an opening. In practice, a slot (not shown) can be provided on the end face of the positioning protruding shaft 13. When the positioning protruding shaft 13 is adapted to be inserted in the positioning After being in the cavity 22, the clamp 5 can be installed in the slot. In this way, the clamp 5 can prevent the two spline teeth 1, 2 from being separated in the axial direction, so that the two spline teeth 1, 2 can move coaxially.
第一花键齿1和第二花键齿2通过如下结构进行传动连接:由于上述位置相对应的安装槽11、21中分别放置有传动件3。这样,当第一花键齿1受力扭转一定角度后便可通过传动件3将扭转力传至第二花键齿2上。 The transmission connection between the first spline teeth 1 and the second spline teeth 2 is carried out through the following structure: the transmission parts 3 are respectively placed in the installation grooves 11 and 21 corresponding to the above positions. In this way, when the first spline tooth 1 is twisted by a certain angle under force, the torsional force can be transmitted to the second spline tooth 2 through the transmission member 3 .
可以理解的是,第一花键齿1的侧端面1a和第二花键齿2的侧端面2a上对应开设安装槽11、21的形状和位置并不限定在上述实施方式,其可以根据实际需要进行调整,例如等距排列的三个对接后呈圆柱状的安装槽11、21。将安装槽11、21等距开设在第一花键齿1和第二花键齿2的端面1a、2a上,是为保证两花键齿之间力的传递更均匀,也更便于装配。 It can be understood that the shapes and positions of the corresponding installation grooves 11, 21 on the side end surface 1a of the first spline tooth 1 and the side end surface 2a of the second spline tooth 2 are not limited to the above-mentioned embodiment, which can be determined according to the actual situation. It needs to be adjusted, for example, three butted cylindrical installation grooves 11 and 21 are arranged equidistantly. The mounting grooves 11, 21 are equally spaced on the end faces 1a, 2a of the first spline tooth 1 and the second spline tooth 2, in order to ensure a more uniform force transmission between the two spline teeth and facilitate assembly.
优选的实施方式中,多个安装槽11、21中设有的传动件3(圆柱销)的长度小于安装槽的长度。进一步的,还可以在圆柱销的外部套设弹性元件4(弹簧),弹性元件4的长度大于圆柱销的长度。进一步,还可以将弹性元件4的长度设置小于安装槽11、21的长度,具体请参见图7。 In a preferred embodiment, the length of the transmission member 3 (cylindrical pin) provided in the multiple installation grooves 11, 21 is shorter than the length of the installation grooves. Further, an elastic element 4 (spring) can also be sheathed outside the cylindrical pin, and the length of the elastic element 4 is greater than that of the cylindrical pin. Further, the length of the elastic element 4 can also be set to be shorter than the lengths of the installation grooves 11 and 21 , please refer to FIG. 7 for details.
以下根据本实施例中传动减震装置的具体实施方式说明上述长度设置的具体作用:发动机动力经第一传动轴8传递给第一花键齿1,第一花键齿1将与第一传动轴8同步转动。进一步的,第一花键齿1的转动将使第一花键齿1与第二花键齿2之间安装槽11、21的相对位置发生改变,其之间的长度减小,但安装槽11、21的长度仍大于弹簧的长度。由于弹簧的长度比圆柱销的长度长,当第一花键齿1的转动角度加大时,弹簧紧接着被压缩,弹簧的弹力使第二花键齿2受力转动。 The specific effect of the above-mentioned length setting is described below according to the specific implementation of the transmission damping device in this embodiment: the engine power is transmitted to the first spline tooth 1 through the first transmission shaft 8, and the first spline tooth 1 will be connected with the first transmission The shaft 8 rotates synchronously. Further, the rotation of the first spline tooth 1 will change the relative position of the installation grooves 11 and 21 between the first spline tooth 1 and the second spline tooth 2, and the length between them will decrease, but the installation groove The length of 11,21 is still greater than the length of spring. Since the length of the spring is longer than that of the cylindrical pin, when the rotation angle of the first spline tooth 1 increases, the spring is compressed immediately, and the elastic force of the spring causes the second spline tooth 2 to rotate under force.
随着弹簧压缩量的增大,第二花键齿2收到的弹簧力也越大。当弹簧的压缩长度和圆柱销的长度一样时,也就是第一花键齿1和第二花键齿2之间的安装槽11、21的长度等于传动件3(圆柱销)的长度时,由于圆柱销的限位作用,弹簧不再被压缩,第一花键齿1和第二花键齿2刚性连接,第一花键齿1和第二花键齿2在圆柱销的作用下同步转动。第二花键齿2通过花键与第二传动轴9连接,动力从第二花键齿2传递至第二传动轴9。 As the amount of spring compression increases, the spring force received by the second spline tooth 2 is also greater. When the compressed length of the spring is the same as the length of the cylindrical pin, that is, when the length of the installation groove 11, 21 between the first spline tooth 1 and the second spline tooth 2 is equal to the length of the transmission member 3 (cylindrical pin), Due to the limiting effect of the cylindrical pin, the spring is no longer compressed, the first spline tooth 1 and the second spline tooth 2 are rigidly connected, and the first spline tooth 1 and the second spline tooth 2 are synchronized under the action of the cylindrical pin turn. The second spline teeth 2 are connected to the second transmission shaft 9 through splines, and power is transmitted from the second spline teeth 2 to the second transmission shaft 9 .
由此可知,通过将相对接的安装槽11、21、传动件3以及弹性元件4的长度设为不同,可以发挥各零部件在传递力过程中的缓冲作用。 It can be seen that by setting the lengths of the abutting installation grooves 11, 21, the transmission member 3 and the elastic member 4 to be different, the buffering effect of each component during the force transmission process can be exerted.
