Description

Technical Field

[0001] This utility model relates to the field of transmission device technology, specifically a worm gear box transmission converter. Background Technology

[0002] Worm gear drives, as an important form of mechanical transmission, are widely used in high-precision transmission scenarios such as industrial robots, precision machine tools, and automated production lines due to their advantages such as large transmission ratio, compact structure, and smooth transmission. The worm gear housing, as the core supporting component of the worm gear drive system, directly affects the transmission accuracy, load-bearing capacity, and equipment lifespan due to the installation stability of the worm and worm gear within it.

[0003] The turbine and worm are mounted in the housing cavity via bearing assemblies. Differences in the machining accuracy of the mating surfaces of the upper and lower housings and the bolt tightening sequence during assembly can easily lead to deviations in the parallelism or center distance between the turbine shaft and the worm shaft, resulting in uneven meshing clearance between the turbine and worm. This exacerbates tooth surface wear after long-term operation. Traditional bearing support structures often use a simple support design with a single-end deep groove ball bearing and the other end angular contact ball bearing. When the transmission system is subjected to combined radial and axial loads, the fit clearance between the inner ring of the bearing and the journal, and between the outer ring of the bearing and the bearing bore of the housing, is prone to increase due to load fluctuations, causing micro-oscillation of the turbine / worm shaft and reducing transmission stability.

[0004] Therefore, a worm gearbox transmission converter is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a worm gear housing transmission converter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A worm gear housing transmission converter includes an integrally formed housing structure. A worm gear transmission component is disposed inside the housing. Worm gear limiting components are disposed on both sides of the housing structure to maintain the stability of the worm gear component during rotation. A worm gear limiting component is disposed on one side of the housing to maintain the stability of the worm gear component during rotation.

[0008] A heat dissipation section is provided on the outer side of the box structure. Both the heat dissipation section and the outer side of the box structure are provided with heat dissipation components, and the heat dissipation components are distributed on the outer side of the box structure to enhance its function.

[0009] As a preferred embodiment of this utility model, the box structure includes a box body, with an upper plate connected to the upper end of the box body and a lower plate fixedly connected to the lower end of the box body. Heat dissipation grooves are provided on both sides of the connection between the upper plate and the upper end of the box body, so that the heat absorbed by the heat dissipation components can be quickly dissipated through the heat dissipation grooves.

[0010] As a preferred embodiment of this utility model, the turbine component is a turbine, the worm component is a worm, the worm meshes with the turbine, both ends of the worm shaft are engaged with worm limiting components, one end of the middle shaft of the worm is engaged with the turbine limiting component, and the other end of the middle shaft of the worm extends through the housing to the outside.

[0011] As a preferred embodiment of this utility model, the worm gear limiting component includes a limiting plate a fixedly connected to the inside of the housing. The limiting plate a has a circular groove in the middle for mounting the bearing a. An inner limiting ring is threaded to one side of the limiting plate a, and the inner limiting ring is sleeved on the outside of the worm gear and is rotatably disposed relative to the worm gear.

[0012] As a preferred embodiment of this utility model, the turbine limiting component includes a limiting plate b fixedly connected to one side of the housing, and a bearing b is provided between the limiting plate b and the central shaft of the turbine.

[0013] As a preferred embodiment of this utility model, one end of the worm gear is connected to a convex end, which extends through the housing to the outside. An end limiting ring is fixedly connected to the outside of the housing, and the end limiting ring is sleeved on the outside of the convex end.

[0014] As a preferred embodiment of this utility model, the heat dissipation part is a groove formed on one side of the upper end of the housing, and the inner side of the groove is set close to the meshing point of the worm and the turbine.

[0015] As a preferred embodiment of this utility model, the heat dissipation component includes a plurality of heat dissipation fins a and a plurality of heat dissipation fins b, wherein the plurality of heat dissipation fins b are distributed on one side of the groove and the outer side of the housing, and the plurality of heat dissipation fins a are distributed on the other side of the housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model adopts an integrated box structure to replace the traditional upper and lower split design, avoiding the problems of parallelism and center distance deviation between the turbine shaft and worm shaft caused by differences in the machining accuracy of the mating surface and the bolt tightening sequence. It ensures the uniformity of the initial meshing clearance between the turbine and worm from the structural source, effectively reducing tooth surface wear during long-term operation.

[0018] 2. The combined design of the worm and turbine limiting components, compared with the traditional simple-supported structure of a single-end deep groove ball bearing and a angular contact ball bearing at the other end, can more accurately constrain the radial and axial displacement of the worm and turbine shafts. The rotational fit between the inner limiting ring and the worm, and the limiting of the end limiting ring on the convex end, further suppress the problem of increased clearance between the bearing inner ring and journal, and between the outer ring and housing bore under combined loads, significantly reducing the risk of micro-oscillation of the turbine / worm shaft and improving transmission stability.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] For an example, please refer to... Figure 1 , 2 3, 4, and 5, a worm gear housing transmission converter, comprising an integrally formed housing structure, an internal worm gear transmission component, worm gear limiting components on both sides of the internal housing structure to maintain the stability of the worm gear component during rotation, a worm gear limiting component on one side of the internal housing structure to maintain the stability of the worm gear component during rotation; a heat dissipation section on one side of the external housing structure, and heat dissipation components on both the external and external sides of the housing structure, with the heat dissipation components distributed on the external side of the housing structure to provide a strengthening effect.

[0031] Please refer to Figure 1 , 2 3, 4, and 5, the housing structure includes housing 1, with an upper plate 3 connected to the upper end of housing 1 and a lower plate 2 fixedly connected to the lower end of housing 1. Heat dissipation grooves 4 are provided on both sides of the connection between the upper plate 3 and the upper end of housing 1, allowing the heat absorbed by the heat dissipation components to dissipate quickly. Traditional worm gear housings often adopt a split casting structure. Differences in the machining accuracy (such as flatness and surface roughness) of the mating surfaces and the bolt tightening sequence during assembly can easily lead to deviations in the parallelism or center distance between the worm shaft and the worm shaft, resulting in uneven meshing clearance and tooth surface wear. This utility model adopts an integrated housing structure. The upper plate 3 is fixed to the upper end of housing 1 by bolts, and the lower plate 2 is fixed to the lower end. This eliminates the split mating surface design, avoiding the problem of decreased shaft positioning accuracy caused by machining errors or assembly deviations of the mating surfaces from the structural source. It significantly improves the overall rigidity of the housing and the consistency of the worm gear installation reference, providing a stable foundation for the precise positioning of the subsequent limiting structure.

[0032] The turbine component is a turbine 18, and the worm component is a worm 15. The worm 15 meshes with the turbine 18. The two ends of the shaft of the worm 15 are engaged with the worm limiting component. One end of the middle shaft of the worm 15 is engaged with the turbine limiting component, and the other end of the middle shaft of the worm 15 extends through the housing 1 to the outside.

[0033] Please refer to Figure 1 , 23, 4 and 5, the worm gear limiting component includes a limiting plate a12 fixedly connected to the inside of the housing 1, the middle of the limiting plate a12 has a circular groove for the bearing a13 to be installed, one side of the limiting plate a12 is threadedly connected to an inner limiting ring 14, and the inner limiting ring 14 is sleeved on the outside of the worm 15 and is rotatably arranged relative to the worm 15. The turbine limiting component includes a limiting plate b16 fixedly connected to one side of the inside of the housing 1, and a bearing b17 is provided between the limiting plate b16 and the middle shaft of the turbine 18.

[0034] The limiting plate a12 is fixed inside the two sides of the housing 1, and a circular groove is opened in the middle to provide a rigid mounting reference for the bearing a13 and constrain the radial displacement of the bearing a13.

[0035] The inner limiting ring 14 is threaded to one side of the limiting plate a12, sleeved on the outside of the worm 15 and rotates relative to the worm 15. The inner limiting ring 14 further restricts the axial movement of the worm 15 by threading with the limiting plate a12 (the axial position can be finely adjusted), and works in conjunction with the bearing a13 to suppress the offset of the worm 15 under radial load.

[0036] The end limiting ring 9 is fixed to the outside of the housing 1 and sleeved on the outside of the protruding end 8 of the worm 15, forming a secondary axial limit on the end of the worm 15 and strengthening the overall support rigidity.

[0037] One end of the worm gear 15 is connected to a protruding end 8, which extends through the housing 1 to the outside. An end limiting ring 9 is fixedly connected to the outside of the housing 1, and the end limiting ring 9 is sleeved on the outside of the protruding end 8.

[0038] The limiting plate b16 is fixed inside the housing 1 on one side, and a bearing b17 is set between it and the middle shaft of the turbine 18. The limiting plate b16 provides a stable installation reference through rigid fixation, while the bearing b17 supports the shaft of the turbine 18 and allows it to rotate freely, while constraining the radial displacement of the shaft, ensuring the parallelism and center distance accuracy between the axis of the turbine 18 and the axis of the worm 15, and realizing the uniform meshing of the turbine and the worm.

[0039] The heat dissipation part is a groove 10 opened on one side of the upper end of the housing 1. The inner side of the groove 10 is set close to the meshing point of the worm gear 15 and the turbine 18. The heat dissipation component includes a number of heat dissipation fins a5 and a number of heat dissipation fins b11. The number of heat dissipation fins b11 are distributed on the groove 10 and the outer side of the housing 1, and the number of heat dissipation fins a5 are distributed on the other side of the housing 1.

[0040] The groove 10 is opened on one side of the upper end of the housing 1, and its inner side is close to the meshing point of the worm gear 15 and the turbine 18 (the main heat source of the transmission system). By shortening the heat transfer path, it accelerates the heat transfer from the meshing area to the surface of the housing.

[0041] Heat dissipation fins b11 are distributed on the groove 10 and one side of the outer side of the housing 1, directly covering the meshing hot spot area. By increasing the heat dissipation area, heat exchange is enhanced. Heat dissipation fins a5 are distributed on the other side of the housing 1, forming a multi-directional heat dissipation layout with heat dissipation fins b11 to avoid local heat accumulation. Heat dissipation slots 4 are opened on both sides of the connection between the upper plate 3 and the upper end of the housing 1, providing a fast heat dissipation channel for the heat absorbed by the heat dissipation fins, further improving the overall heat dissipation efficiency.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
