Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of large equipment transportation, specifically to a motor adjustment structure. Background Technology
[0002] Motor adjustment mechanisms are widely used in industrial applications, especially in automated production lines, material handling, and the processing and inspection of large workpieces. However, when the track of a motor adjustment mechanism is too long, it may cause a series of problems, including but not limited to structural stability, operational safety, and maintenance difficulty.
[0003] Excessive track length can also increase safety hazards during operation. For example, insufficient or asymmetrical connection points between the scaffolding and the building structure, or improper or unreliable connections between the scaffolding and the building structure's beams and columns, can all compromise structural stability. Furthermore, maintenance difficulty increases with track length. Longer tracks require more maintenance to ensure proper operation, such as regularly checking the straightness of the guide rails and the wear of the sliders, as well as inspecting and adjusting transmission components such as gears, racks, and belts. Longer tracks may also increase frictional resistance during movement, affecting operating speed and efficiency, especially when rapid movement of heavy materials is required. Utility Model Content
[0004] The purpose of this invention is to provide a motor adjustment structure that uses a linear guide rail installation method to ensure that the motor adjustment direction is linear motion; at the same time, the clearance between the gear and rack is adjusted by a spring, which absorbs the deviation caused by excessive rack travel through a buffering mechanism. This solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor adjustment structure, including a guide rail, a transmission mechanism, and a moving mechanism. The guide rail includes a steel rail, a rack, and a gear. The steel rail surface is provided with a rack, which meshes with the gear for transmission. The gear is rotatably connected to a reducer of the transmission mechanism. The input shaft of the reducer is connected to the output shaft of the motor. The moving mechanism is disposed above the steel rail and includes a fixing device.
[0006] Preferably, the number of rails is 2, and each rail surface is provided with a directional bearing.
[0007] Preferably, the moving mechanism is provided with a bearing.
[0008] More preferably, the number of bearings is 6.
[0009] Preferably, the rack is further provided with a lubrication gear, which meshes with the rack for transmission.
[0010] Preferably, the lubricating gear is also connected to a fixing device.
[0011] Preferably, the fixing device includes a fixing mounting plate, which is connected to the speed reducer.
[0012] More preferably, the fixing device further includes a guide rail, which is connected to the fixing mounting plate.
[0013] Preferably, the fixing device further includes an adjustment mechanism, which includes a compression spring and an adjusting screw.
[0014] More preferably, the compression spring and the adjusting screw are rotatably connected, and the tension of the compression spring is adjusted by adjusting the adjusting screw.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The novel adjustment mechanism in this experiment uses a compression spring to press and fix the mounting plate, ensuring proper meshing of the gear and rack; no manual adjustment is required, resulting in good and stable performance; the structure is simple and easy to install.
[0017] 2. The compression spring elasticity can be adjusted according to actual application needs to adapt to racks of various lengths, ensuring correct meshing between the gears and racks, thereby ensuring transportation stability.
[0018] 3. By incorporating lubricating gears, the friction between the gears and rack is reduced, thereby improving operating speed, efficiency, and service life. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention proposes a motor adjustment structure, including a guide rail mechanism, a transmission mechanism, and a moving mechanism. The guide rail includes a steel rail 4, a rack 9, and a gear 6. The rack 9 is provided on the surface of the steel rail 4. The rack 9 meshes with the gear 6 for transmission. The gear 6 is rotatably connected to the reducer 8 of the transmission mechanism. The input shaft of the reducer 8 is connected to the output shaft of the motor 1. The moving mechanism 10 is disposed above the steel rail and includes a fixing device.
[0027] Preferably, the number of rails 4 is 2, and each rail 4 is provided with a directional bearing 2 on its surface.
[0028] Preferably, the moving mechanism 10 is provided with a bearing 3.
[0029] More preferably, the number of bearings 3 is 6.
[0030] Preferably, the rack 9 is further provided with a lubricating gear 7, which meshes with the rack 9 for transmission.
[0031] More preferably, the lubricating gear 7 is also connected to a fixing device.
[0032] Preferably, the fixing device includes a fixing mounting plate 13, which is connected to the reducer 8.
[0033] More preferably, the fixing device further includes a guide rail 5, which is connected to the fixing mounting plate 13.
[0034] Preferably, the fixing device further includes an adjustment mechanism, which includes a compression spring 12 and an adjusting screw 11.
[0035] More preferably, the compression spring 12 and the adjusting screw 11 are rotatably connected, and the tension of the compression spring 12 is adjusted by adjusting the adjusting screw 11.
[0036] The compression spring 12 and the adjusting screw 11 are respectively installed at both ends of the fixed mounting plate 13.
[0037] Please see Figure 4The working principle of a motor adjustment structure based on Embodiment 1 is as follows: A linear guide rail is used for installation. The input shaft of the reducer 8 is connected to the output shaft of the motor 1. The reducer 8 is mounted on a fixed mounting plate 13 of a fixed device. The fixed mounting plate 13 is used to fix the positions of the motor 1 and the reducer 8. The fixed mounting plate 13 is connected to the guide rail 5. Oriented bearings 2 are located on both sides of the rail 4. Bearings 3 are mounted on the moving mechanism 10 (which carries the large equipment to be transported). This ensures the moving accuracy of the moving mechanism's base frame. By starting the motor 1, the reducer 8 is driven to rotate. The reducer 8 drives the gear 6 to mesh and rotate on the rack 9, driving the moving mechanism 10 to move forward. The lubricating gear 7 is located in front of the gear 6 in the positive direction of movement and is used to lubricate the rack 9. The elasticity of the compression spring 12 is adjusted by adjusting the screw 11, thus adjusting the gap between the gear 6 and the rack 9 during movement. This absorbs the movement deviation caused by the rack having too long a stroke through buffering.
[0038] As is well known to those skilled in the art, when the rail 4 is long enough, there will be slight straightness deviations. This utility model uses the elasticity of the compression spring to adjust the gap between the gear 6 and the rack 9 during movement, so that the gear 6 and the rack 9 mesh perfectly, and the motor adjustment structure achieves the optimal movement state.
[0039] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
