Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically relating to a speed reducer that is easy to maintain. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] Authorized publication number "CN216923117U" discloses a maintainable speed reducer, including a speed reducer frame, a support plate, a top block, a bottom plate, a protective cover, support ribs, and a speed reducer assembly. This maintainable speed reducer features a mounting frame on the top of the support plate. The mounting frame engages with bosses at both ends of the support plate via slots on its inner wall. Protective covers are movably connected to both ends of the mounting frame via connecting screws, protecting the internal speed reducer. The installation method is simple and convenient. A handle is movably installed on the top of the mounting frame to prevent scratches from sharp edges of components during installation. When the protective cover is subjected to impact, the impact force is transmitted to the reinforcing layer through the support ribs. The reinforcing layer increases the strength of the protective cover from the inside, preventing deformation during impact and effectively improving the safety of the internal speed reducer while preventing damage to the outer casing.

[0004] The aforementioned new reinforcing layer improves the strength of the protective cover from the inside, preventing it from deforming when subjected to impact. However, the outer shell is fixed with bolts, which makes it difficult to quickly disassemble the reducer and threaten its internal components. Utility Model Content

[0031] Gearbox body 1;

[0032] Upper cover 2 is fixedly connected to the upper end of the reducer body 1;

[0033] Insertion slot 17, there are two insertion slots 17, both of which are opened at the lower end of the upper shell cover 2;

[0034] There are two fixing plates 3. Both fixing plates 3 are fixedly connected to the upper end of the reducer body 1 and slide in the two insertion slots 17 respectively.

[0035] The fixing components are provided in multiple sets. Each set of fixing components includes a fixing slot 4, a spring groove 5, a spring push plate 6, a fixing block 7, and a fixing spring 8. The fixing slot 4 is opened on one side of the fixing plate 3. The spring groove 5 is opened on one side of the inner wall of the insertion groove 17. The spring push plate 6 is slidably connected in the spring groove 5. The fixing block 7 is fixedly connected to one side of the spring push plate 6 and matches the fixing slot 4. The fixing spring 8 is fixedly connected to one side of the spring push plate 6 and one side of the inner wall of the spring groove 5.

[0036] In a specific embodiment of this utility model, the upper cover 2 is a protective shell fixed to the upper end of the reducer body 1, protecting the reducer body 1 during operation. When the reducer body 1 malfunctions or requires regular maintenance, the upper cover 2 can be quickly disassembled. A fixing component is provided between the reducer body 1 and the upper cover 2, enabling quick installation of the upper cover 2. When the upper cover 2 needs to be installed, the insertion slot 17 at the lower end of the upper cover 2 is aligned with the upper end of the fixing plate 3, and then the upper cover 2 is inserted into the notch at the upper end of the reducer body 1. The fixing block 7 located in the insertion slot 17 and the fixing plate 3... Upon contact, the fixing plate 3 presses against the inclined surface of the fixing block 7, causing the fixing block 7 to push the spring push plate 6 into the spring groove 5 and compress the fixing spring 8 to retract. When the fixing plate 3 is fully inserted into the insertion groove 17, the previously compressed fixing spring 8 rebounds and inserts the fixing block 7 into the fixing slot 4 to complete the fixing of the fixing slot 4, thereby fixing the upper cover 2 and completing the sealing of the upper end of the reducer body 1. The upper cover 2 can be quickly installed and removed through the fixing assembly. When the reducer body 1 is in use, the upper cover 2 seals and protects the upper end of the reducer body 1, which can improve maintenance efficiency during maintenance.

When it is necessary to disassemble the upper cover 2, the sliding block 13 is pulled to disassemble the upper cover 2. After the upper cover 2 is disassembled, the upper cover 2 can be lifted by the sliding block 13.

[0041] Please refer to the details. Figures 1-4 A fixed pull block 12 is fixedly connected to the upper end of the pull groove 9, and the fixed pull block 12 is sleeved on the outside of the sliding pull block 13.

[0042] In this embodiment: the fixed pull block 12 is fixedly connected to the upper shell cover 2. When disassembling, the operator places his palm on the upper end of the fixed pull block 12, inserts his fingers into the fixed pull block 12, and then grips it tightly to pull the fixed pull block 12 upwards to complete the disassembly of the upper shell cover 2. After disassembly, the operator holds the fixed pull block 12 and the sliding pull block 13 to lift the upper shell cover 2, thereby opening the upper end of the reducer body 1 for maintenance.

[0043] Please refer to the details. Figures 1-4 The lower end of the fixed pull block 12 is provided with an arc-shaped groove 14, which is arc-shaped.

[0044] In this embodiment: the arc groove 14 is arc-shaped and matches the arc of a human hand. When the operator holds the fixed pull block 12, it matches the arc of the arc groove 14, making it easy for the operator to pull the sliding pull block 13 to disassemble.

[0045] Please refer to the details. Figures 1-4 The lower end of the reducer body 1 is fixedly connected to a base plate 15, and the upper end of the base plate 15 is provided with multiple fixing holes 16.

[0046] In this embodiment: the fixing block 12 is located at the lower end of the reducer body 1 to fix the reducer body 1, and the fixing hole 16 is opened in the fixing base plate 15. The reducer body 1 is fixed to the working surface by bolts and screws.

[0047] The working principle and usage process of this utility model: The upper cover 2 is a protective shell fixed to the upper end of the reducer body 1, protecting the reducer body 1 during operation. When the reducer body 1 malfunctions or requires regular maintenance, the upper cover 2 can be quickly disassembled. A fixing component is provided between the reducer body 1 and the upper cover 2, which enables the quick installation of the upper cover 2. When the upper cover 2 needs to be installed, the insertion slot 17 at the lower end of the upper cover 2 is aligned with the upper end of the fixing plate 3, and then the upper cover 2 is inserted into the notch at the upper end of the reducer body 1. The fixing block 7 located in the insertion slot 17 and the fixing plate... 3. Upon contact, the fixing plate 3 presses against the inclined surface of the fixing block 7, causing the fixing block 7 to push the spring push plate 6 into the spring groove 5 and compress the fixing spring 8 to retract. When the fixing plate 3 is fully inserted into the insertion groove 17, the previously compressed fixing spring 8 rebounds and inserts the fixing block 7 into the fixing slot 4 to complete the fixing of the fixing slot 4, thereby fixing the upper cover 2 and completing the sealing of the upper end of the reducer body 1. The upper cover 2 can be quickly installed and removed through the fixing assembly. When the reducer body 1 is in use, the upper cover 2 seals and protects the upper end of the reducer body 1, which can improve maintenance efficiency during maintenance.
