Description
Technical Field
The invention relates to a synchronous transmission stepless amplitude modulation box of vibration equipment, belonging to the technical field of stepless continuous amplitude adjustment of vibration devices.
Background
The vibration frequency and vibration amplitude are key parameters that determine the performance of the vibrating equipment. In order to adapt to the vibration requirements of different products and different production processes, different vibration forces are provided according to the requirements of different working stages (such as the processes of starting, vibrating, stopping, waiting and the like), which is beneficial to improving the product quality, ensuring the working reliability of equipment, prolonging the service life of the equipment, protecting the environment and the like. The adjustment of the amplitude is an effective method for realizing the adjustment of the vibration force, so that the vibration equipment has a corresponding function of adjusting the vibration amplitude on line in real time, and the vibration amplitude adjusting device is one of the core structures of the vibration equipment.
The existing amplitude modulation mechanism is a back wheel amplitude modulation mechanism, and the technology disclosed in patent 201521129396.6 is that amplitude modulation is realized through transmission of an external gear set. The amplitude modulation gear and the corresponding amplitude modulation shaft are in a different-axis relation, the engagement between the amplitude modulation gear and the amplitude modulation shaft is that the external gear is engaged with the external gear, and only a few parts of teeth participate in the engagement transmission. The amplitude modulation gear in the amplitude modulation gear set is a duplicate gear, a large gear in the duplicate gear is meshed with the amplitude modulation shaft, and a small gear is meshed with the first amplitude modulation gear, so that the correct meshing relation between the amplitude modulation gear and the amplitude modulation shaft is ensured. In addition, in a back wheel mechanism in meshing transmission of the external gear, the rigidity difference between the amplitude modulation gear and the amplitude modulation shaft causes the difference of the meshing relationship between the amplitude modulation gear and the amplitude modulation shaft, and the failure of the amplitude modulation shaft is accelerated.
The existing amplitude modulation mechanism only determines partial meshing teeth to participate in power transmission work due to partial meshing of external teeth, but not all teeth of a transmission gear participate in transmission, and the rigidity of a transmission structure is difficult to ensure, so that the bearing capacity, the working reliability and the service life of the amplitude modulation mechanism are limited to a certain extent, and an amplitude modulation shaft is seriously abraded and rapidly fails in the using process. If the problems are solved by simply increasing the strength of the gear, the difficulty, complexity and mechanical structure specification of the manufacturing are increased, and the cost is greatly increased.
Therefore, the development of a vibration device real-time online stepless vibration amplitude adjustment technology with strong bearing capacity, reliable work, strong durability, stable performance and considerable economy is a problem to be solved urgently by technical personnel in the field.
Disclosure of Invention
The invention provides a synchronous transmission stepless amplitude modulation box of vibration equipment with matching of inner teeth and outer teeth, aiming at the problems of poor meshing degree and serious abrasion of an amplitude modulation shaft caused by the meshing of the outer teeth between an amplitude modulation gear and the amplitude modulation shaft in the existing amplitude modulation mechanism.
The technical scheme for solving the technical problems is as follows: the vibration equipment synchronous transmission stepless amplitude modulation box is characterized by comprising a first amplitude modulation shaft, a second amplitude modulation shaft, a first shaft and a second shaft which are sequentially arranged; the first amplitude modulation shaft is provided with a first amplitude modulation gear, the first amplitude modulation gear is provided with inner helical teeth, the first amplitude modulation shaft is provided with outer helical teeth matched with the inner helical teeth of the first amplitude modulation gear, and the end part of the first amplitude modulation shaft is provided with the first gear; a second amplitude modulation gear is arranged on the second amplitude modulation shaft, the second amplitude modulation gear is provided with second inner helical teeth, second outer helical teeth matched with the second inner helical teeth of the second amplitude modulation gear are arranged on the second amplitude modulation shaft, a fifth gear and a second gear are arranged at the end part of the second amplitude modulation shaft, and the second gear is an intermediate gear; a sixth gear and a third gear are mounted at the end part of the first shaft, and the third gear is an idle gear; a fourth gear is arranged at the end part of the second shaft; the first gear is meshed with the second gear, the second gear is meshed with the third gear, the third gear is meshed with the fourth gear, the fifth gear is meshed with the sixth gear, and the first amplitude modulation gear is meshed with the second amplitude modulation gear; and amplitude modulation clamps are arranged on the first amplitude modulation gear and the second amplitude modulation gear.
In the technical scheme, when the amplitude-modulation clamp is used for simultaneously pushing the first amplitude-modulation gear and the second amplitude-modulation gear to respectively move along the axial directions of the corresponding first amplitude-modulation shaft and the second amplitude-modulation shaft, the first amplitude-modulation shaft and the second amplitude-modulation shaft which are matched with the inner teeth of the first amplitude-modulation gear and the second amplitude-modulation shaft are respectively driven by the first amplitude-modulation gear and the second amplitude-modulation gear to synchronously rotate, so that the relative phase of the first amplitude-modulation shaft and the second amplitude-modulation shaft is adjusted, and the amplitude is adjusted, because the first amplitude-modulation gear and the second amplitude-modulation gear are matched with the first amplitude-modulation shaft and the second amplitude-modulation shaft through the inner teeth, all gear teeth are matched and transmitted (called full-tooth transmission for short), and the full-tooth transmission: firstly, the rigidity of a matching structure is ensured, so that the matching is stable; secondly, when the first amplitude modulation gear and the second amplitude modulation gear are pushed to perform amplitude modulation, all the inner teeth of the first amplitude modulation gear and the second amplitude modulation gear and all the outer teeth of the first amplitude modulation shaft and the second amplitude modulation shaft bear loads at the same time, and the whole bearing capacity is greatly improved. Meanwhile, due to full-tooth transmission, the load born by each pair of the participating transmission gear teeth is greatly reduced, so that the abrasion of the inner teeth of the first amplitude modulation gear and the second amplitude modulation gear and the outer teeth of the first amplitude modulation shaft and the second amplitude modulation shaft is very small, and the rotation angle synchronism of the first amplitude modulation shaft and the second amplitude modulation shaft is good.
On the basis of the technical scheme, in order to achieve the convenience of use and the stability of equipment, the invention can also make the following improvements on the technical scheme:
furthermore, the inner helical teeth of the first amplitude modulation gear and the outer helical teeth of the first amplitude modulation shaft have the same tooth number, module and helix angle.
Furthermore, the inner helical teeth of the second amplitude modulation gear and the outer helical teeth of the second amplitude modulation shaft have the same tooth number, module and helix angle.
Further, the outer teeth of the first amplitude modulation gear and the outer teeth of the second amplitude modulation gear have the same tooth number and module.

Furthermore, the amplitude modulation clamp comprises two shifting fork plates, one ends of the two shifting fork plates are connected through a limiting sleeve, the other ends of the two shifting fork plates are respectively fixed in the middle of one linkage plate, and the movable shaft is inserted in the limiting sleeve; the two linkage plates are arranged between the two shifting fork plates, and the upper part and the lower part between the two linkage plates are respectively connected through a positioning shaft; the linkage plate is provided with a pair of through holes for the first amplitude modulation shaft and the second amplitude modulation shaft to pass through.
Furthermore, the moving shaft is provided with a limiting ring, and the moving shaft clamps and fixes the two shifting fork plates and the limiting sleeve on the moving shaft through the limiting ring and the nut.
Furthermore, two rows of positioning shafts are arranged, and each row is provided with three positioning shafts; the three positioning shafts are respectively positioned at the two ends and the middle of the linkage plate.
Furthermore, shoulders are arranged on two sides of the first amplitude modulation gear and the second amplitude modulation gear, bearings are arranged on the shoulders, and through holes of the linkage plate are sleeved on the bearings.
Further, a sliding sleeve is further arranged in the shoulder.
Furthermore, the linkage plate is a rectangular plate or an elliptical plate.
Furthermore, the through holes for the first amplitude modulation shaft and the second amplitude modulation shaft to pass through and the fixed positions of the linkage plate and the shifting fork plate are on the same plane.
The invention has the advantages that: the amplitude modulation gear is in coaxial relation with the corresponding amplitude modulation shaft, the amplitude modulation gear is provided with external teeth and internal teeth simultaneously, the internal teeth of the amplitude modulation gear are matched with the external teeth of the amplitude modulation shaft (namely, the amplitude modulation shaft is a long-shaft-shaped external gear), the matching between the amplitude modulation gear and the amplitude modulation shaft is that full teeth between the internal gear and the external gear participate in matching transmission, and the amplitude modulation gear is coaxial amplitude modulation. The amplitude modulation gear set composed of two amplitude modulation gears slides on the two amplitude modulation shafts along the axial direction to achieve the purpose of changing the relative phase angle between the two amplitude modulation shafts, and the moving distance of the amplitude modulation gears corresponds to the phase adjustment angle, so that the stepless continuous adjustment of the vibration amplitude is realized. The amplitude of the vibration mechanism is adjusted through adjusting the phase, and therefore the vibration force is adjusted.
