Abstract
The utility model discloses a water pump used on a hydrodynamic retarder. The water pump comprises a transmission main shaft bearing cooling device and a water pump body, wherein the water pump body is connected on the outer end face of the transmission main shaft bearing cooling device, a coolant gallery (1) is arranged in the transmission main shaft bearing cooling device, and the coolant gallery (1) is communicated with the water pump body. The water pump used on the hydrodynamic retarder has the advantages of being reasonable in structural design, convenient to manufacture and install, and low in manufacturing cost. According to the water pump used on the hydrodynamic retarder, a bearing on a transmission main shaft of the hydrodynamic retarder can be cooled, hydraulic oil in an oil pump on the hydrodynamic retarder can be cooled, service lives of the bearing on the transmission main shaft and the hydraulic oil are prolonged, and stability of working of the water pump is achieved due to the fact that mechanical energy is adopted as power.
Description
Technical field
The utility model relates to a kind of hydrodynamic retarder, and is particularly a kind of for the water pump on the hydrodynamic retarder.
Background technique
Be provided with cooling system on the existing hydrodynamic retarder, this cooling system comprises the water channel that is positioned on the housing, this water channel connects external water pump and radiator successively by pipeline, the radiation fan of promising radiator heat-dissipation is set at the radiator place, structure although it is so can be cooled off hydraulic oil, but it has following deficiency:
1, this cooling system can't be to the bearing cooling that is used for support and fixed conveyor main shaft on the hydrodynamic retarder, in case the bearing working overlong time, bearing temperature raises, and bearing life will shorten greatly;
2, this cooling system can't cool off the gear pump on the hydrodynamic retarder, causes the hydraulic fluid temperature on the gear pump to raise, and greatly shorten the working life of hydraulic oil, simultaneously, has caused the gear life in the gear pump to shorten;
3, because this system adopts external water pump, so that the manufacture cost of system is higher;
4, because this water pump adopts electric power as kinetic energy, in case circuit breaks down, this water pump can't be worked, and causes cooling system to cool off.
The model utility content
The purpose of this utility model just provides a kind of water pump on the hydrodynamic retarder of being used for that can have cooling bearing and gear pump.
The purpose of this utility model is to realize by such technological scheme, a kind of for the water pump on the hydrodynamic retarder, this water pump comprises transmission main shaft bearing cooler and water pump body, described water pump body is connected on the exterior edge face of transmission main shaft bearing cooler, be provided with cooling water channel in the transmission main shaft bearing cooler, this cooling water channel is communicated with water pump body.
Wherein, the transmission main shaft bearing cooler comprises interconnective cooling lid A and cooling lid B, center at cooling lid A and cooling lid B is provided with the transmission main shaft mounting hole, described cooling water channel is separately positioned in cooling lid A and the cooling lid B, and A is provided with water intake and the water outlet that runs through cooling lid A at the cooling lid.
Wherein, water pump body comprises interconnective water pump lid A and water pump lid B, described water pump lid B is connected with the exterior edge face of cooling lid A, B is provided with placed cavity at the water pump lid, in placed cavity, be provided with the water pump vane with rotatingshaft, described rotatingshaft passes water pump lid B, cooling lid A and cooling lid B successively, and described cooling water channel is communicated with placed cavity.
Owing to having adopted technique scheme, the utlity model has reasonable in design, manufacturing is easy for installation, manufacture cost is lower advantage, adopt it not only can lower the temperature to the bearing on the transmission main shaft of hydrodynamic retarder, and can also lower the temperature to the hydraulic oil in the hydrodynamic retarder oiling pump, bearing on the transmission main shaft and working life of hydraulic oil have been prolonged, simultaneously, adopt mechanical energy as power, so that pump working has more stability.
