Description

Technical Field

[0001] The utility model relates to the technical field of cooling discs, in particular to a cooling coil device built into a reducer. Background Art

[0002] A reducer is a power transmission mechanism that can reduce the number of revolutions of a motor to the required number of revolutions. Reducers are widely used in both the transportation field and the mechanical industry. Reducers, especially high-power reducers, generate a lot of heat due to high-speed operation. If the heat is not dissipated in time, it will affect the working efficiency of the reducer and shorten the service life of the reducer. Therefore, a cooling device is generally used to cool the reducer.

[0003] 1) The cooling method of using a motor pump plus a plate heat exchanger is adopted. Since this technology requires an additional motor pump to provide power for the cooling oil circuit, it generally has disadvantages such as high noise, heavy weight, and large size.

[0004] 2) Use cooling coils to cool the reducer. The cooling coils include: a chassis and a coil disposed on the chassis, but the heat dissipation area of ​​the cooling coils is small, resulting in poor cooling effect of the cooling coils and poor heat dissipation effect of the reducer.

[0005] In summary, how to provide a cooling coil so as to effectively solve the problem of small heat dissipation area and poor cooling effect of the cooling coil is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, an improved built-in cooling coil device for a reducer is provided.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a cooling coil device built into a reducer, comprising a chassis installed in a reducer housing, two coils connected to the chassis, and a joint piece is provided at the connection between the coil and the chassis;

[0008] The two-way coil forms a double-way spiral wrap-around structural layout;

[0009] The coil comprises a copper tube and a fin group evenly arranged on the surface of the copper tube.

[0010] By adopting the above technical solution, fins with the same pitch are added around the copper tube, which can increase the heat dissipation area of ​​the copper tube and improve the cooling capacity of the cooling coil. When the cooling coil is cooling, part of the heat generated by the reducer can be transferred to the fins on the coil, and the other part can be directly transferred to the coil. In this way, the reducer is cooled by the coil and the fins at the same time, the heat dissipation area is large, and the cooling effect is better.

[0011] Furthermore, the fin assembly described in the utility model includes a plurality of fins with the same pitch.

[0012] Furthermore, the spiral wrapping segment structural layout described in the present invention includes a structure in which a double-path spiral wrapping segment is directly formed from the joint piece upward, or the cooperation of a bottom double single-path extension structure and an upper double-path spiral wrapping segment, or the cooperation of two double-path spiral wrapping segments bent into a fixed angle between the upper and lower sections.

[0013] By adopting the above technical solution, the coil can be bent or arranged into a specific structural layout as needed to avoid the gear structure in the corresponding reducer housing, and the overall structural layout is more compact and reasonable, with high space utilization.

[0014] The beneficial effects of the utility model are as follows: the utility model overcomes the problems existing in the cooling coil in the prior art and has the following advantages:

[0015] 1. The cooling coil is built into the box, and the coil can be set to the corresponding avoidance structure according to the actual position of the gear; 2. No motor pump, low noise; 3. No need to provide additional power supply; 4. The cooling coil is embedded in the groove of the box, which is convenient and simple to fix; 5. No motor pump, light weight; 6. Effectively solve the problem of small heat dissipation area and poor cooling effect of the cooling coil; 7. The bending of the entire finned copper tube can ensure that the tube body is leak-free in the box, and can be bent into any shape according to installation requirements.
