Description
本发明涉及齿轮传动技术领域,具体涉及一种能消除相交轴锥齿轮传动副传动间隙的消隙装置。The invention relates to the technical field of gear transmission, in particular to a backlash eliminating device capable of eliminating the transmission gap of the intersecting shaft bevel gear transmission pair.
普通情况下,锥齿轮与锥齿轮啮合传动均有传动间隙,当锥齿轮传动副需要正反转动的情况下,会产生一定的空回量,降低传动精度。因此,在需要精确传动的装置中,须使用能消除锥齿轮啮合传动间隙的消隙装置以便消除空回量。申请号为CN201510117508.4的专利公开了相交轴锥齿轮传动间隙消除机构,其技术特征是:包括传动轴、平键、从动锥齿轮、压盖、螺钉、蝶形弹簧、花键轴、挡圈、卡簧、扭转弹簧、复合螺母、调整垫、主动锥齿轮。所述的从动锥齿轮通过平键、压盖、螺钉固定联接在传动轴上,所述的主动锥齿轮通过花键配合在花键轴上并可以轴向移动,主动锥齿轮的小端通过碟形弹簧、压盖、螺钉弹性限位,主动锥齿轮的大端花键轴轴向连接有凋整垫、复合螺母,所述的挡圈通过平键与卡簧限位在花键轴上,所述的扭转弹簧一端卡入挡圈的端面孔中,另一端卡入复合螺母的端面孔中,所述的复合螺母在扭转弹簧弹力作用下保持旋转的运动扭力,复合螺母转动会轴向推动调整垫和主动锥齿轮向前移动,锥齿轮传动的间隙被排除,所述的碟形弹簧作用力小于扭转弹簧对复合螺母产生的轴向作用力。这种相交轴锥齿轮传动间隙消除机构的缺点是:①构成间隙消除机构的调整垫、复合螺母、扭转弹簧、挡圈、卡簧以串连的结构装在花键轴上,导致相交轴锥齿轮传动间隙消除机构的轴向尺寸较大,结构不紧凑;②复合螺母的内螺纹须根据花键轴的直径配做,故该锥齿轮传动间隙消除机构不具备通用性。Under normal circumstances, there is a transmission gap between the bevel gear and the bevel gear meshing transmission. When the bevel gear transmission pair needs positive and negative rotation, a certain amount of empty return will be generated to reduce the transmission accuracy. Therefore, in a device that requires precise transmission, an anti-backlash device that can eliminate the bevel gear engagement transmission gap must be used in order to eliminate the empty back volume. The patent with application number CN201510117508.4 discloses an intersecting shaft bevel gear transmission clearance elimination mechanism, and its technical characteristics are: including the transmission shaft, flat key, driven bevel gear, gland, screw, butterfly spring, spline shaft, gear Rings, circlips, torsion springs, compound nuts, adjusting pads, driving bevel gears. The driven bevel gear is fixedly connected to the transmission shaft through a flat key, a gland, and a screw. The driving bevel gear is fitted on the spline shaft through a spline and can move axially. The small end of the driving bevel gear passes through Disc spring, gland, screw elastic limit, the large end spline shaft of the active bevel gear is axially connected with a shim and a compound nut, and the retaining ring is limited on the spline shaft by a flat key and a snap spring , One end of the torsion spring is snapped into the end face of the retaining ring, and the other end is snapped into the end face of the compound nut, the compound nut maintains the rotational torsion force under the elastic force of the torsion spring, and the rotation of the compound nut will be axial Pushing the adjustment pad and the active bevel gear to move forward, the clearance of the bevel gear transmission is eliminated, and the acting force of the disc spring is smaller than the axial acting force of the torsion spring on the compound nut. The shortcomings of this clearance elimination mechanism for intersecting shaft bevel gears are: ① The adjustment pad, compound nut, torsion spring, retaining ring, and circlip that constitute the clearance elimination mechanism are installed on the spline shaft in a series structure, resulting in intersecting shaft cones The axial dimension of the gear transmission clearance elimination mechanism is large, and the structure is not compact; ②The internal thread of the compound nut must be matched according to the diameter of the spline shaft, so the bevel gear transmission clearance elimination mechanism is not universal.

锥齿轮传动间隙消隙装置的工作原理:请参阅图1,所述锥齿轮3的轴孔与所述传动轴1之间的配合具有适宜的间隙,使锥齿轮3可以沿传动轴1的轴向滑移。在锥齿轮3安装于传动轴1之前,先将所述锥齿轮传动间隙消隙装置装在传动轴1上并紧靠传动轴1的轴肩2,再将锥齿轮3安装于传动轴1上并紧靠所述锥齿轮传动间隙消隙装置,从而完成相交轴锥齿轮传动副的安装。这时,第一垫环4与第二垫环5接触而没有间隙(请参阅图4、图8),两根所述施力杆12均位于第一垫环4的第一圆锥面71的外侧(请参阅图8、图9),而锥齿轮3的轮齿与啮合锥齿轮13的轮齿之间有间隙。请参阅图2,均匀地旋转两根所述螺杆10,使铰接于螺杆10的所述支脚11抵紧传动轴1的圆柱面,而所述滑块9沿第一导槽81向远离传动轴1的方向滑移,使两个滑块9之间的距离拉开,这样,两根C形的施力杆12逐渐被拉直,并使两根施力杆12产生弹性力,在弹性力的作用下,两根施力杆12的中间部位分别从第一圆锥面71的外侧(请参阅图9)向第一轴孔61移动(请参阅图2),即两根施力杆12的中间部位分别沿第一圆锥面71由第一圆锥面71的低处(请参阅图8)向第一圆锥面71的高处移动(请参阅图10),两根施力杆12的中间部位顶住第一垫环4的第一圆锥面71与第二垫环5的朝向第一垫环4的端面上,从而将第一垫环4与第二垫环5分离,使第一垫环4与第二垫环5之间产生间隙(请参阅图10)。两个滑块9之间的距离被拉开得越远,两根C形的施力杆12被拉得越直,两根施力杆12的中间部位分别沿第一圆锥面71移动到越高的位置,第一垫环4与第二垫环5被分离得越开,第一垫环4与第二垫环5之间的间隙越大。请参阅图1,第一垫环4与第二垫环5的分离运动会推动锥齿轮3沿传动轴1的轴向朝啮合锥齿轮13的方向移动,使锥齿轮3的轮齿与啮合锥齿轮13的轮齿互相靠近,并最终消除锥齿轮3与啮合锥齿轮13的啮合传动间隙。Working principle of the clearance clearance device of the bevel gear transmission: please refer to FIG. 1, the fit between the shaft hole of the bevel gear 3 and the transmission shaft 1 has an appropriate clearance, so that the bevel gear 3 can be along the shaft of the transmission shaft 1 Slide towards. Before the bevel gear 3 is installed on the transmission shaft 1, the bevel gear transmission clearance anti-backlash device is first installed on the transmission shaft 1 and is close to the shoulder 2 of the transmission shaft 1, and then the bevel gear 3 is installed on the transmission shaft 1 And close to the bevel gear transmission gap anti-backlash device, thereby completing the installation of the intersecting shaft bevel gear transmission pair. At this time, the first backing ring 4 is in contact with the second backing ring 5 without a gap (see FIGS. 4 and 8), and the two force applying rods 12 are both located on the first conical surface 71 of the first backing ring 4 Outside (see Figures 8 and 9), there is a gap between the gear teeth of the bevel gear 3 and the gear teeth of the bevel gear 13. Referring to FIG. 2, the two screw rods 10 are rotated uniformly, so that the legs 11 hinged to the screw rod 10 abut against the cylindrical surface of the transmission shaft 1, and the slider 9 moves away from the transmission shaft along the first guide groove 81 Slide in the direction of 1, so that the distance between the two sliders 9 is widened, so that the two C-shaped force bars 12 are gradually straightened, and the two force bars 12 generate elastic force. Under the action of, the middle parts of the two forcing rods 12 respectively move from the outside of the first conical surface 71 (see FIG. 9) to the first shaft hole 61 (see for FIG. 2), that is, the two forcing rods 12 The middle part moves along the first conical surface 71 from the lower part of the first conical surface 71 (see FIG. 8) to the upper part of the first conical surface 71 (see FIG. 10), the middle part of the two forcing rods 12 The first conical surface 71 of the first gasket ring 4 and the end surface of the second gasket ring 5 facing the first gasket ring 4 separate the first gasket ring 4 from the second gasket ring 5 to make the first gasket ring 4 and a gap between the second backing ring 5 (see FIG. 10). The farther the distance between the two sliders 9 is, the more straight the two C-shaped force bars 12 are pulled, and the middle parts of the two force bars 12 move along the first conical surface 71 to In the high position, the more the first gasket ring 4 and the second gasket ring 5 are separated, the greater the gap between the first gasket ring 4 and the second gasket ring 5. Please refer to FIG. 1, the separation movement of the first gasket ring 4 and the second gasket ring 5 will push the bevel gear 3 to move in the direction of the meshing bevel gear 13 along the axial direction of the transmission shaft 1, so that the gear teeth of the bevel gear 3 and the meshing bevel gear The gear teeth of 13 are close to each other, and finally the mesh transmission gap between the bevel gear 3 and the meshing bevel gear 13 is eliminated.
锥齿轮传动间隙消隙装置的有益效果:请参阅图1、图2,所述锥齿轮传动间隙消隙装置装在传动轴1上,其整装结构为第一垫环4与第二垫环5之间夹着调隙机构。因为第一垫环4及第二垫环5均为片状,故轴向尺寸小,又因为组成调隙机构的两个滑块9、两根螺杆10、两个支脚11、两根施力杆12均分布于传动轴1的径向面内(请参阅图2),施力杆12、螺 杆10的直径都较小(请参阅图6),滑块9、支脚11虽然在传动轴1的轴向的尺寸略大,但滑块9镶嵌于第一垫环4的第一导槽81中且支脚11也隐藏于第一导槽81中(请参阅图2、图7),所以锥齿轮传动间隙消隙装置的轴向尺寸小,结构紧凑。Beneficial effect of the clearance clearance device of the bevel gear transmission: please refer to FIG. 1 and FIG. 2, the clearance clearance device of the bevel gear transmission is installed on the transmission shaft 1, and its whole structure is a first gasket ring 4 and a second gasket ring The gap adjustment mechanism is sandwiched between 5. Because the first backing ring 4 and the second backing ring 5 are both sheet-shaped, the axial dimension is small, and because of the two sliders 9, two screws 10, two legs 11, and two force-bearing components that make up the gap adjustment mechanism The rods 12 are all distributed in the radial plane of the drive shaft 1 (see FIG. 2), the diameters of the force applying rod 12 and the screw rod 10 are small (see FIG. 6), and the slider 9 and the leg 11 are located on the drive shaft 1 The axial dimension of is slightly larger, but the slider 9 is embedded in the first guide groove 81 of the first backing ring 4 and the leg 11 is also hidden in the first guide groove 81 (see FIGS. 2 and 7), so the cone The gear drive clearance anti-backlash device has a small axial size and a compact structure.
