Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a cycloid-specific outdoor waterproof direct-connected motor. Background Art

[0002] The cycloid pinwheel reducer is a novel transmission device that uses the planetary transmission principle and cycloid pin gear meshing. The entire transmission device of the cycloid pinwheel reducer can be divided into three parts: input part, reduction part, and output part. A double eccentric sleeve with a 180° offset is installed on the input shaft. Two roller bearings called swing arms are installed on the eccentric sleeve to form an H mechanism. The center holes of the two cycloid wheels are the raceways of the swing arm bearings on the eccentric sleeves, and the cycloid wheels are meshed with a group of circularly arranged pin teeth on the pin gear to form an internal meshing reduction mechanism with a tooth difference of one tooth (in order to reduce friction, in reducers with small speed ratios, the pin teeth are equipped with pin gear sleeves);

[0003] Cycloid pinwheel reducers are also very common in outdoor use, but there are still many problems with the use of cycloid pinwheel reducers currently on the market. In view of the fact that existing cycloid pinwheel reducers are easily affected by the external environment when used outdoors, causing liquid to penetrate into the generator and damage it, resulting in a reduction in its service life and causing unnecessary trouble for users, we propose a cycloid-specific outdoor waterproof direct-connected motor.

[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] Reference Figure 1-5 The utility model provides an embodiment of a cycloid dedicated outdoor waterproof direct-connected motor, comprising a first waterproof shell 3, a second waterproof shell 8 is correspondingly installed at the outer end of the first waterproof shell 3, the docking ports of the two waterproof shells 8 are the same in size, but since the motor is installed inside the second waterproof shell 8, the second waterproof shell 8 is longer than the first waterproof shell 3, a cycloid pinwheel reducer body 21 is installed inside the second waterproof shell 8, both ends of the cycloid pinwheel reducer body 21 are fixedly connected with mounting blocks 20, both ends of the outer side of the second waterproof shell 8 and the mounting block 20 are threadedly connected with third positioning bolts 19, the mounting block 20 can contact the inner wall of the second waterproof shell 8, and screw holes are opened at the upper and lower ends of the second waterproof shell 8 to cooperate with the third positioning bolts 19 to fix the cycloid pinwheel reducer body 21, and screw holes are also opened inside the mounting block 20 to cooperate with it;

[0027] The inner end of the first waterproof shell 3 is fixedly connected with a sealing layer 18, and the sealing layer 18 is extended outwardly. Its purpose is that when the two waterproof shells are docked, the sealing layer 18 can enter the interior of the second waterproof shell 8, so as to achieve a sealing effect and effectively prevent water drops from leaking from the connection between the two shells. The upper end of the sealing layer 18 contacts the inner wall of the second waterproof shell 8. The first connecting plate 2 is fixedly connected to both ends of the first waterproof shell 3, and the second connecting plate 5 is fixedly connected to both ends of the second waterproof shell 8. The first connecting plate 2 corresponds to the second connecting plate 5. The output end of the cycloid pinwheel reducer body 21 passes through the second waterproof shell 8 and is provided with a motor shaft 7 outwardly. The waterproof shells can be quickly docked and installed through the mutual correspondence between the two connecting plates;

[0028] The outer end of the first connecting plate 2 is fixedly connected to the limiting block 12, and the interior of the second connecting plate 5 is provided with a limiting groove 14, the limiting block 12 corresponds to the limiting groove 14, the limiting block 12 and the limiting groove 14 can be quickly connected, which improves the convenience of its installation, and the limiting block 12 is provided with a slot 16 inside, and the bottom of the slot 16 is fixedly connected with two springs 17, the other end of the spring 17 is fixedly connected to the limiting plate 15, and the other end of the limiting plate 15 is fixedly connected with a positioning block 11, and the positioning block 11 is movably installed inside the first connecting plate 2, and the positioning block 11 can be moved inside the slot 16 by the spring 17. When corresponding, it is only necessary to press the positioning block 11 inward to recover it to the inside of the slot 16, ensuring that there is no obstruction when the limiting block 12 enters the inside of the limiting groove 14;

[0029] A positioning groove 13 is provided in the vertical direction of the first connecting plate 2, and the positioning block 11 corresponds to the positioning groove 13. When the positioning block 11 passes through the positioning groove 13, the internal spring 17 acts to make the positioning block 11 pop outward to engage with the positioning groove 13. The engagement operation can be achieved through the cooperation between the positioning block 11 and the positioning groove 13, which can prevent the positioning block 11 from falling off. When removing the positioning block 11, the positioning block 11 can be removed by pressing it inward and then pulling it outward.

[0030] The upper end of the first waterproof shell 3 is fixedly connected to the first mounting plate 1, and the upper end of the second waterproof shell 8 is fixedly connected to the second mounting plate 10. The first mounting plate 1 and the second mounting plate 10 are threadedly connected with the second positioning bolts 9. The bottoms of the first waterproof shell 3 and the second waterproof shell 8 are fixedly connected to the mounting base 4, and the mounting base 4 is threadedly connected with the first positioning bolt 6. Twisting the second positioning bolt 9 on the top can double-lock the two waterproof shells, thereby improving the waterproof sealing performance of the waterproof shells when in use and improving the service life of the internal cycloid pinwheel reducer body 21. Under the action of the mounting base 4 and the first positioning bolt 6, the entire waterproof shell can be fixed and used stably in conjunction with the cycloid pinwheel reducer body 21.

[0031] Working principle: When the device is used, firstly, the motor shaft 7 of the cycloid reducer body 21 is aligned with the mounting hole on the second waterproof shell 8, and the mounting blocks 20 at both ends of the cycloid reducer body 21 are aligned with the inner wall of the second waterproof shell 8. The cycloid reducer body 21 can be locked by screwing the third positioning bolt 19 to ensure the installation stability of the cycloid reducer body 21 inside the second waterproof shell 8. Then, the first connecting plate 2 on the first waterproof shell 3 is aligned with the second connecting plate 5 on the second waterproof shell 8, and the limiter is pressed inward. The positioning block 11 on the block 12 can be retracted inwardly under the action of the spring 17, and then the limit block 12 is matched with the limit groove 14, so that the two waterproof shells can be quickly docked. When the positioning block 11 passes through the positioning groove 13, the internal spring 17 causes the positioning block 11 to pop outward and engage with the positioning groove 13 to achieve rapid engagement. Finally, by screwing the second positioning bolt 9 above, the two waterproof shells can be doubly locked, thereby improving the waterproof sealing performance of the waterproof shell when in use and increasing the service life of the internal cycloid pinwheel reducer body 21.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
