When the damping adjusting mechanism is used, firstly, the elastic member 300 with a proper elastic coefficient is selected according to a preset damping requirement, and then the size of the pressing member 200 is determined according to the size of the spline portion 120 and the inner space of the mounting cavity 110. After the pressing member 200 is sleeved outside the spline portion 120, the elastic member 300 is also placed into the mounting cavity 110, and at this time, one end of the elastic member 300 will be pressed against the pressing member 200. The fixing seat 400 is sleeved outside the spline seat 100, the fixing portion 410 extends into the mounting cavity 110 and is fixed after being movably matched with the pressing member 200, at this time, the other end of the elastic member 300 is pressed against the fixing portion 410, and the elastic member 300 is pressed between the pressing member 200 and the fixing portion 410. Compared with the traditional mode (the torsion spring or two ends of the spring need to be twisted and clamped in different slots of the damper shell). The damping adjusting mechanism can change the contact force of the elastic member 300 to the spline housing 100 (i.e. change the damping) by changing the interval between the fixing portion 410 and the pressing member 200 (the interval adjustment can be realized by the relative movement of the fixing portion 410 and the pressing member 200), and the adjustment is more convenient.
In one embodiment, when assembling the damping adjustment mechanism, the pressing member 200 may be first placed inside the mounting cavity 110, while the pressing member 200 is sleeved outside the spline portion 120, and then the elastic member 300 is placed in the mounting cavity 110, one end of the elastic member 300 abuts against the pressing member 200, and the other end of the elastic member 300 faces the opening of the mounting cavity 110. The fixing seat 400 is sleeved outside the spline seat 100, at this time, the side portion of the fixing seat 400 is abutted against the side portion of the spline seat 100, and the spline seat 100 can rotate relative to the fixing seat 400. The fixing portion 410 is inserted into the mounting cavity 110 along with the movement of the fixing base 400, and the fixing portion 410 is movably engaged with the pressing member 200, at this time, two ends of the elastic member 300 respectively contact with the pressing member 200 and the fixing portion 410, and the elastic member 300 is correspondingly contracted by the relative movement of the pressing member 200 and the fixing portion 410. For example: when the elastic member 300 contracts, the elastic member 300 can generate radial deformation (referring to the radial direction of the elastic member 300) towards the side portion of the spline housing 100, that is, different radial deformation degrees can apply different resisting forces to the side portion of the spline housing 100, so that the damping between the spline housing 100 and the fixed seat 400 is changed.
As shown in fig. 1 and fig. 2, in an embodiment, the spline housing 100 includes a collision sleeve body 130 and a mounting plate 140, the mounting plate 140 is mounted at an end of the collision sleeve body 130, the mounting plate 140 and the collision sleeve body 130 enclose the mounting cavity 110 inside the collision sleeve body 130, the mounting plate 140 is provided with a first spline opening 141, the spline portion 120 is mounted in the mounting cavity 110, and the first spline opening 141 corresponds to the spline portion 120. One end of the spline portion 120 is connected to the mounting plate 140, and the other end of the spline portion 120 protrudes out of the abutting sleeve body 130. Specifically, the spline portion 120 determines the shape of the spline portion 120 according to a spline rod or lead screw, and the spline portion 120 may be a cylinder or a prism. In this embodiment, the spline portion 120 is a cylinder, that is, after the spline portion 120 is installed in the installation cavity 110, the installation cavity 110 is divided into an annular cavity. Further, in order to ensure the sealing performance of the integral structure of the spline housing 100, the interference sleeve body 130, the mounting plate 140 and the spline portion 120 are integrally formed. Further, consider that elastic component 300 can take place deformation in installation cavity 110, the tip protrusion of spline portion 120 in conflict cover body 130 has realized promptly that spline portion 120 wholly runs through conflict cover body 130 avoids elastic component 300 to produce unexpected conflict with the lead screw when warping in installation cavity 110, has guaranteed damping adjustment mechanism's result of use.
In one embodiment, one end of the elastic member 300 abuts against the pressing member 200, the other end of the elastic member 300 abuts against the fixing portion 410, and the elastic member 300 is sleeved outside the spline portion 120. Further, the length of the spline portion 120 can be lengthened, that is, after the fixing seat 400 is sleeved outside the spline seat 100, the spline portion 120 can penetrate out of the fixing seat 400, so that a gap between the spline portion 120 and the fixing portion 410 is avoided, the sealing performance of the space where the elastic member 300 is located is ensured, and the use effect of the damping adjusting mechanism is improved.
As shown in fig. 1, in one embodiment, the pressing element 200 includes a pressing plate 210 and a pressing sleeve 220. The pressing plate 210 is mounted at the end of the pressing sleeve 220, the pressing plate 210 is provided with an adaptation port 211, the adaptation port 211 is communicated with the inside of the pressing sleeve 220, the pressing plate 210 and the pressing sleeve 220 are sleeved outside the spline portion 120, the plate edge of the pressing plate 210 is abutted against the side of the abutting sleeve body 130, and a moving gap 230 for the fixing portion 410 to extend into is reserved between the pressing sleeve 220 and the spline portion 120.
Specifically, the pressure plate 210 is designed according to the cavity shape of the mounting cavity 110 of the spline housing 100 and the diameter of the spline portion 120 (e.g., the cylindrical spline portion 120). For example: when the mounting cavity 110 is an annular cavity, the spline portion 120 is a cylindrical spline portion 120, the pressing plate 210 is a circular plate, the aperture of the adapting opening 211 on the pressing plate 210 is consistent with the diameter of the spline portion 120, that is, after the pressing plate 210 is sleeved outside the spline portion 120, the inner annular edge of the pressing plate 210 is abutted against the spline portion 120, and the outer annular edge of the pressing plate 210 is abutted against the inner side of the spline base 100. Such an embodiment can ensure that the pressing plate 210 can move up and down in the mounting cavity 110 along the height direction of the spline portion 120 (i.e. the direction extending from one end of the spline portion 120 to the other end) or the depth direction of the spline housing 100, and at this time, can ensure that the pressing member 200 compresses the elastic member 300 more uniformly. Further, the fixing portion 410 extends into the moving gap 230, and in the process, one side of the fixing portion 410 abuts against the spline portion 120, and the other side of the fixing portion 410 movably fixes with the abutting sleeve body 130. Such an embodiment described above makes the installation of the damping adjustment mechanism more compact.
As shown in fig. 1, in an embodiment, the fixing base 400 includes a mounting sleeve body 420, the fixing portion 410 includes a fixing plate 411 and a fixing sleeve 412, the mounting sleeve body 420 is sleeved outside the abutting sleeve body 130, the fixing plate 411 is installed at one end of the mounting sleeve body 420, a second spline opening for the spline portion 120 to penetrate out is provided on the fixing plate 411, the fixing sleeve 412 is installed on the fixing plate 411, the fixing sleeve 412 is communicated with the second spline opening, the fixing sleeve 412 is sleeved outside the spline portion 120, and the fixing sleeve 412 extends into the moving gap 230 and the abutting sleeve 220 to be movably matched. Specifically, the mounting sleeve 420, the fixing plate 411 and the fixing sleeve 412 are integrally formed. When the mounting sleeve body 420 is sleeved outside the abutting sleeve body 130, the end of the spline portion 120 passes through the second spline opening and penetrates out of the fixing plate 411, and meanwhile, the mounting cavity 110 in the spline seat 100 can be sealed through the fixing plate 411. In addition, since the spline portion 120 is fixed to the mounting plate 140 only by the end portion, sometimes an installation error occurs in the spline portion 120 in the mounting cavity 110 due to the influence of a machining error, and at this time, the fixing sleeve 412 is sleeved outside the spline portion 120, so that the installation error of the spline portion 120 can be effectively eliminated, and the installation effect of inserting the spline rod into the spline base 100 is improved.
As shown in fig. 1, in an embodiment, a first installation gap 500 is left between the pressing sleeve 220 and the side portion of the collision sleeve body 130 for the elastic element 300 to extend into, a second installation gap 600 is left between the fixing sleeve 412 and the side portion of the collision sleeve body 130 for the elastic element 300 to extend into, the first installation gap 500 is communicated with the second installation gap 600, and the elastic element 300 elastically collides with the side portion of the collision sleeve body 130 in the first installation gap 500 and the second installation gap 600. Specifically, in the first and second installation gaps 500 and 600, the distance between the pressing sleeve 220 and the interference sleeve body 130 is smaller than the distance between the fixing sleeve 412 and the interference sleeve body 130. Further, after the elastic element 300 enters the first installation gap 500, the pressing sleeve 220 and the abutting sleeve body 130 respectively abut against two sides of the elastic element 300, and a certain gap is left between the fixing sleeve 412 and the abutting sleeve body 130 of the elastic element 300 in the second installation gap 600. That is, the above-mentioned embodiment can firstly ensure the pressing effect of the pressing member 200 on the elastic member 300 (to limit the elastic member 300 from being accidentally separated from the first installation gap 500), and secondly provide a deformation space for the radial deformation of the elastic member 300, so that the deformation force of the elastic member 300 can effectively act on the interference sleeve body 130.
In one embodiment, the pressing sleeve 220 is provided with a first thread, and the fixing sleeve 412 is provided with a second thread adapted to the first thread. Specifically, the thread fit between the pressing sleeve 220 and the fixing sleeve 412 is realized through the first thread and the second thread, and in the above embodiment, on one hand, the relative adjustment between the pressing sleeve 220 and the fixing sleeve 412 can be realized, and on the other hand, the fixing of the pressing sleeve 220 and the fixing sleeve 412 at the preset position can also be realized, so that the installation and the adjustment of the damping adjustment mechanism are more convenient.
As shown in fig. 3, in one embodiment, the damping adjustment mechanism further includes a mounting housing 700. The fixing seat 400 is provided with a fixing bump 430, the mounting shell 700 is sleeved outside the fixing seat 400, and the side part of the mounting shell 700 is abutted to the fixing bump 430. Specifically, the mounting shell 700 protects the fixing seat 400 and the internal components (e.g., the spline seat 100, the spline portion 120, the elastic member 300, etc.). Meanwhile, the fixing protrusion 430 may be an elastic block, that is, after the housing is sleeved outside the fixing base 400, the housing is fixed to the fixing base 400 by elastic deformation of the fixing protrusion 430. This is just one example of an embodiment, for example: a fixing groove corresponding to the fixing protrusion 430 may be formed in the mounting shell 700, and the fixing protrusion 430 is inserted into the fixing groove to fix the mounting shell 700 to the fish fixing seat 400.
In one embodiment, the damping adjustment mechanism further comprises a wear layer. The wear-resistant layer is attached to the inner side of the spline housing 100, and the wear-resistant layer is used for abutting against the elastic member 300. Specifically, the wear-resistant layer is wear-resistant ceramic or wear-resistant rubber. At this moment, the spline housing 100 collides with the elastic member 300 through the wear layer, and the elastic member 300 generates resistance when rubbing with the inside of the spline housing 100 according to the above embodiment, so that the spline rod (lead screw) moves more stably after being inserted into the spline housing 100.
As shown in fig. 1 to 3, in an embodiment, a damper includes the damping adjustment mechanism according to any one of the above embodiments, and further includes: and the wire rod piece 800 is inserted into the spline part 120 to be matched with the damping adjusting mechanism.
When the damper is used, the wire rod member 800 is inserted into the damping adjustment mechanism, and the preset damping of the damper is determined by the damping adjustment mechanism. When the damping needs to be adjusted again, compared to the conventional damper (both ends of the torsion spring or the spring need to be twisted and caught in different slots of the damper mounting case 700). The damping adjusting mechanism can change the contact force of the elastic member 300 to the spline housing 100 (i.e. change the damping) by changing the interval between the fixing portion 410 and the pressing member 200 (the interval adjustment can be realized by the relative movement of the fixing portion 410 and the pressing member 200), and the damping adjustment is more convenient.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
