Description

Technical Field

[0001] This utility model relates to the technical field of gearboxes for speed reducers, and more particularly to an installation structure for a cooling coil of a speed reducer. Background Technology

[0002] Gearbox lubricating oil often utilizes room-temperature fresh water, seawater, or other liquids flowing through cooling pans and pipes to absorb the heat dissipated by the high-temperature lubricating oil, thereby reducing the temperature of the lubricating oil and achieving the function of cooling the lubricating oil.

[0003] In the current technology, the installation structure of cooling coils is complicated, and the contact area between conventional cooling coils and the lubricating oil in the gearbox is small, resulting in poor conduction performance and insufficient cooling effect. Summary of the Invention

The inclined spiral body facilitates the disassembly and assembly of the cooling coil, has a large contact area with the lubricating oil in the gearbox, good conductivity, and obvious cooling effect, which greatly improves the working efficiency of the gearbox.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The above-mentioned installation structure of the reducer cooling coil includes the coil body comprising: a spiral body and an arc-shaped tube, one end of the spiral body being connected to the arc-shaped tube, and the other end of the spiral body being connected to two connecting tubes;

[0008] The helix is ​​in an inclined spiral shape.

[0009] In the above-mentioned installation structure of the reducer cooling coil, the spiral body includes a plurality of ring bodies connected in sequence, the plurality of ring bodies are parallel to each other, and the plurality of ring bodies are all inclined.

[0011] In the above-described installation structure of the reducer cooling coil, the central axis of the coil body and the central axes of the two connecting pipes are parallel.

[0012] The two connecting pipes are arranged symmetrically along the central axis of the coil body.

[0013] In the aforementioned installation structure of the reducer cooling coil, two of the connecting pipes are installed on the reducer gearbox housing.

[0014] In the aforementioned mounting structure of the reducer cooling coil, the cooling coil can pass through the mounting hole of the reducer gearbox housing;

[0015] The overall outer diameter of the cooling coil is smaller than the inner diameter of the mounting hole.

[0016] The aforementioned installation structure for the cooler cooling coil further includes: a cover plate, which is installed at the mounting hole of the gearbox housing of the reducer, and both connecting pipes of the cooler cooling coil pass through the cover plate and are welded to the cover plate;

[0017] The cover plate is fixedly connected to the gearbox housing of the reducer by multiple bolts.

[0018] In the aforementioned installation structure of the reducer cooling coil, a flange is provided on the outer wall of the cover plate, and a step is formed between the flange and the outer wall of the cover plate. The step abuts against the mounting hole on the reducer gearbox housing, and the flange is fixedly connected to the reducer gearbox housing by bolts.

[0019] The aforementioned installation structure for the reducer cooling coil further includes: two connectors, which are respectively installed on the two connecting pipes of the cooling coil;

[0024] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:

[0025] (1) The inclined coil body of this utility model reduces the overall outer diameter of the cooling coil, which can reduce the diameter of the mounting hole on the gearbox, making it easier to process and also easier to disassemble and assemble the cooling coil, thus improving the overall processing and disassembly efficiency.

[0026] (2) The inclined spiral of this utility model is designed with each ring inclined, which reduces the outer diameter of the spiral but increases the outer diameter of a single ring, thereby increasing the contact area between the ring and the lubricating oil in the gearbox, improving conductivity, and significantly improving the cooling effect, thus greatly improving the working efficiency of the gearbox.
