Abstract
Description
A gear reducer Technical Field
[0001] This utility model relates to the field of gear reducers, specifically a gear reducer. Background Technology
[0002] The core principle of a gear reducer is to transmit power through the meshing of gears with different numbers of teeth, using the transmission ratio to reduce speed and increase torque. The small gear on the input shaft drives the large gear on the output shaft to rotate; the difference in the number of teeth causes the output speed to decrease proportionally, while the torque increases inversely.
[0003] Traditional gear reducers are typically mounted on a fixed base, and the output shaft height is not adjustable. When the input shaft height of the driven equipment does not match the output shaft of the reducer, additional shims or custom mounting brackets are required, resulting in cumbersome installation, poor compatibility, and high maintenance costs. Especially in scenarios where equipment needs to be frequently replaced or production line layout needs to be adjusted, the lack of a quick height adjustment function severely restricts efficiency. Therefore, a new type of gear reducer is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a gear reducer to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A gear reducer includes a gear reducer body and a mounting base. The gear reducer body is fixedly connected to the upper end of the mounting base, and a base is slidably mounted on the bottom of the mounting base. An adjustment component is provided between the base and the mounting base.
[0007] The adjustment assembly is provided in multiple sets. Each set of adjustment assembly includes two sets of lower crossbars and one set of upper crossbars. The two sets of lower crossbars are fixed to the base, and the upper crossbar is fixed to the mounting base. The upper crossbar is located between the two sets of lower crossbars.
[0008] Both sets of lower crossbars are slidably mounted with lower sliders, and two sets of upper sliders are slidably mounted on the upper crossbars. Support arms are rotatably mounted on both sets of lower sliders. The ends of the two sets of support arms are rotatably mounted to the side walls of the two sets of upper sliders, and the two sets of support arms are interleaved. A drive assembly is provided between the two sets of lower sliders.
[0009] Preferably, the two sets of support arms are located between the two sets of lower sliders, the two sets of upper sliders are located between the two sets of support arms, the two sets of lower crossbars are symmetrical to each other, and the upper crossbars and lower crossbars are parallel to each other.
[0010] Preferably, the drive assembly includes a dual-axis cylinder, which is fixed to the upper end of the base and located between two sets of support arms. The output ends of both ends of the dual-axis cylinder are rotatably mounted with fixing rings, and the two sets of fixing rings are respectively fixed to the side walls of the two sets of lower sliders.
[0011] Preferably, the mounting base has a groove at the bottom, the upper end of the adjustment component is located in the groove, and the lower end of the adjustment component is mated with the groove to reduce the volume occupied by the adjustment component.
[0012] Preferably, the upper end of the base is fixedly connected to multiple sets of vertical rods, and the mounting seat is slidably mounted on the multiple sets of vertical rods. The upper ends of the multiple sets of vertical rods are all threaded with connecting columns.
[0013] Preferably, each of the multiple sets of connecting columns has an extension column threaded to its upper end, and a baffle is rotatably mounted on the upper end of the multiple sets of extension columns, with the gear reducer body located below the baffle.
[0014] The beneficial effects of this utility model are:
[0015] This invention controls the movement of the lower slider through a drive component, which in turn causes the crossed support arms to expand or retract, achieving smooth lifting and lowering of the mounting base. This ensures that the output shaft height of the gear reducer body is precisely matched to the input shaft of the driven equipment, eliminating the need for additional pads or custom brackets.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] A gear reducer, as shown in Figures 1-4, has a gear reducer body 4 mounted on a mounting base 2. The mounting base 2 slides on the upper end of a base 1 and is supported and stabilized by an adjustment component. The adjustment component can also adjust the height between the mounting base 2 and the base 1, thereby adjusting the height of the gear reducer body 4. This allows the output end of the gear reducer body 4 to drive equipment of different heights, resulting in greater adaptability.
[0025] At least two sets of adjustment components are provided. The upper end of each set of adjustment components is fixed to the bottom of the mounting base 2 via the upper crossbar 9, and the lower end of each set of adjustment components is fixed to the upper end of the base 1 via the lower crossbar 10.
[0026] In use, when the output end of the gear reducer body 4 is not at the same height as the drive end of the driven device, the drive assembly is activated. The drive assembly pulls the two sets of lower sliders 11 to slide on the lower crossbar 10. The two sets of lower sliders 11 move closer, which in turn moves the lower ends of the two sets of support arms 12 closer together. This causes the upper sliders 13 at the upper ends of the two sets of support arms 12 to slide on the upper crossbar 9. The two sets of upper sliders 13 move closer to each other, and the height between the upper sliders 13 and the lower sliders 11 increases. This drives the mounting base 2 to rise, increasing the height of the gear reducer body 4, so that the output end of the gear reducer body 4 is at the same height as the input shaft of the driven device. No additional pads or custom brackets are required, making it highly adaptable.
[0027] As shown in Figures 1-4, looking down from above the gear reducer body 4, the upper crossbar 9 is located between the two sets of lower crossbars 10, the two sets of support arms 12 are located between the two sets of lower sliders 11, and the two sets of upper sliders 13 are located between the two sets of support arms 12. The two sets of lower crossbars 10 are symmetrical to each other, and the upper crossbar 9 and the lower crossbar 10 are parallel to each other. When the drive assembly is unfolded, it drives the mounting base 2 and the base 1 to move closer together, thus folding up the lower structure of the gear reducer body 4. The upper crossbar 9, lower crossbar 10, support arms 12 and other structures can be retracted without affecting the folding up.
[0028] As shown in Figures 2-4, the output ends of the dual-axis cylinder 15 (model PNEUMAX) pull the two sets of lower sliders 11 to slide through the fixing ring 14. The diameter of the dual-axis cylinder 15 is smaller than the width of the upper slider 13.
[0029] As shown in Figures 1-3, after the adjustment component is stored, it is stored in the groove 8, reducing the space occupied when not in operation.
[0030] The upper end of the base 1 is fixedly connected to multiple sets of vertical rods 3, and the mounting seat 2 is slidably installed on the multiple sets of vertical rods 3. The upper ends of the multiple sets of vertical rods 3 are all threaded with connecting posts 5.
[0031] The vertical rod 3 limits the sliding path of the mounting base 2 to prevent the mounting base 2 from tilting relative to the base 1, and the connecting column 5 blocks the upper end of the vertical rod 3 to prevent the support from detaching.
[0032] Both ends of the connecting column 5 have internally threaded holes, which are threaded to the vertical rod 3 and the extension rod respectively. Therefore, a baffle 7 can be extended and installed on the vertical rod 3, so that the baffle 7 can block the upper end of the gear reducer body 4, which has a certain function of protecting against rain and dust, and increases the adaptability of the gear reducer body 4 outdoors.
[0033] The working principle of the gear reducer provided by this utility model is as follows:
[0034] In use, when the output end of the gear reducer body 4 is not at the same height as the drive end of the driven device, the drive assembly is activated. The drive assembly pulls the two sets of lower sliders 11 to slide on the lower crossbar 10. The two sets of lower sliders 11 move closer, which in turn moves the lower ends of the two sets of support arms 12 closer together. This causes the upper sliders 13 at the upper ends of the two sets of support arms 12 to slide on the upper crossbar 9. The two sets of upper sliders 13 move closer to each other, and the height between the upper sliders 13 and the lower sliders 11 increases. This drives the mounting base 2 to rise, increasing the height of the gear reducer body 4, so that the output end of the gear reducer body 4 is at the same height as the input shaft of the driven device. No additional pads or custom brackets are required, making it highly adaptable.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
