Abstract
The utility model discloses a support for a cooling fan of a diesel engine. The support comprises a fan bracket and a main shaft, wherein a straight-through forced filling oil cup is mounted on the fan bracket; the fan bracket is assembled at one end of the main shaft through a bearing; an automatic speed-regulation device is be fixedly mounted at the other end of the main shaft; and a belt pulley is fixedly mounted on the main shaft between the fan bracket and the automatic speed-regulation device. In the support, the rotational speed of the cooling fan can be regulated according to the temperature variation of cooling water, so that the favorable cooling effect on the diesel engine can be ensured, and the energy consumption is reduced. The support for the cooling fan of the diesel engine can be widely applied to various diesel engines for construction machinery.
Description
Technical field
The utility model relates to a kind of cooling fan support of transportation diesel.
Background technique
Transportation diesel generally adopts cooling fan that diesel engine is dispelled the heat.Along with the diesel engine strengthening degree improves constantly, the cooling fan that requires diesel engine to be equipped with must possess enough cooling capacities.Especially on the heavy-duty car that engineering machinery such as bulldozer, excavator are used, because its operating environment is abominable, and load can increase suddenly or reduce in the work, therefore the heat of diesel engine generation also can be inhomogeneous, this has just proposed very high requirement to the radiation system that diesel engine is equipped with, in order to reach good radiating effect, will control cooling fan and keep high rotational speed, therefore also will consume more power and energy.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency at prior art exists provides a kind of good cooling results, the low cooling fan support that is used for diesel engine of energy consumption.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The cooling fan support that is used for diesel engine, comprise fan bracket and main shaft, the straight-through type forced filling oil cup is installed on the described fan bracket, described fan bracket is assemblied in an end of main shaft by bearing, the other end at main shaft is installed with automatic speed governing device, and the center fixed that is positioned at fan bracket and automatic speed governing device on main shaft is equipped with belt pulley.
Described automatic speed governing device is a magnetic clutch.
Described fan bracket is assemblied in an end of main shaft by thrust bearing and roller bearing.
Described magnetic clutch is fixed on the main shaft by nut, is provided with spacer between described magnetic clutch and the fan bracket.
The connecting end of described fan bracket and belt pulley is provided with gland, is provided with sealing cover between the other end of described fan bracket and the main shaft.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is installed with magnetic clutch on main shaft, magnetic clutch can be regulated speed of cooling fan according to the temperature variation of cooling water, therefore both can guarantee the cooling effect that diesel engine is good, the bigger energy consumption that has caused when also having avoided the high rotating speed of available technology adopting control cooling fan.
The utility model is provided with gland at the connecting end of fan bracket and belt pulley, between the other end of fan bracket and main shaft, be provided with sealing cover, adopt the grease lubrication of sealing, make the cooling fan support have good running accuracy and working life, can be widely used in various engineering machinery with on the diesel engine.
