Abstract
The utility model discloses a cooling device for a speed reducer. The device comprises a speed reducer box, a torque converter, and a driving shaft, a driven shaft and a clutch which are arranged inside the speed reducer box. The torque converter is connected with an oil return pipe, the other end of which is communicated and connected with the top of the speed reducer box. A port of the oil return pipe at the top of the speed reducer box is connected with a sprinkler. Due to the adoption of such a technical scheme by the cooling device of the utility model, engine oil in the torque converter is adjusted via a pressure valve and is sprayed from the oil return pipe to the speed reducer. As the inlet of the oil return pipe is located at the top of the speed reducer, inlet engine oil is sprayed in from top to down, so that all components in the speed reducer are cooled, thereby guaranteeing normal operation of all the components in the speed reducer.
Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of cooling unit of retarder.
Background technique
In the gearbox of big machinery, the multi-change speed transmission is arranged in the casing, include forward clutch, back clutch etc.Because gearbox is compact, volume is little, makes the drive mechanism temperature of gearbox to raise, and pressure increases, and can cause structure such as gearbox clutch to burn after long-time the use.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of cooling unit of retarder is provided, and it can improve the working environment of retarder.
For realizing above-mentioned purpose; The technological scheme of the utility model is the cooling unit of a kind of retarder of design; Said device comprises driving shaft, driven shaft, the clutch that reduction case, torque-converters and reduction case are inner, it is characterized in that said torque-converters is connected with return tube; The other end of said return tube connects with the reduction case top and is connected, and said return tube is connected with shower nozzle on the port that is positioned at the reduction case top.
Wherein, said torque-converters is connected with return tube through pressure valve.
The advantage and the beneficial effect of the utility model are: the cooling unit of this retarder is because after adopting such scheme; The torque-converters inner engine oil is regulated through pressure valve and is sprayed in the retarder by return tube; Because the return tube inlet is at the retarder top; The machine oil of entering is sprayed into from top to bottom, make interior all parts of retarder all obtain cooling action.Guarantee that each component runs well in the gearbox.
Description of drawings
Fig. 1 is the structural representation of the cooling unit of the utility model retarder.
Among the figure: 1, reduction case; 2, driving shaft; 3, driven shaft; 4, one or two speed clutch; 5, three or four speed clutch; 6, back clutch; 7, torque-converters; 8; Pressure valve; 9, return tube; 10, shower nozzle.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1; The utility model is a kind of cooling unit of retarder; Comprise driving shaft 2, driven shaft 3, clutch that reduction case 1, torque-converters 7 and reduction case are inner; Said torque-converters 7 is connected with return tube 9 through pressure valve 8, and said return tube 9 the other ends connect with reduction case 1 top and are connected, and said return tube 9 is connected with shower nozzle 10 on the port that is positioned at casing 1 top.
After adopting the present invention program; Torque-converters 7 inner engine oils are regulated through pressure valve 8 and are sprayed into reduction case 1 by return tube 9; Because return tube 9 inlets spray into the machine oil of entering at reduction case 1 top from top to bottom, make reduction case 1 interior all parts all obtain cooling action.Guarantee that each component runs well in the reduction case 1.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (2)
1. the cooling unit of a retarder; Said device comprises driving shaft, driven shaft, the clutch that reduction case, torque-converters and reduction case are inner; It is characterized in that; Said torque-converters is connected with return tube, and the other end of said return tube connects with the reduction case top and is connected, and said return tube is connected with shower nozzle on the port that is positioned at the reduction case top.
