Abstract
The utility model provides a kind of engine blower support, the Al-alloy parts that described engine blower support is high pressure die casting, described engine blower support has bearing hole and mounting hole, described engine blower support has loss of weight chamber, described loss of weight chamber is in the backside openings of described engine blower support but be not extended to the front of described engine blower support, and described loss of weight chamber is radial arrangement around described bearing hole.The utility model has overcome the problem that thin walled structures support easily produces noise.
Description
Technical field
The utility model designed engines cooling system, is specifically related to engine blower support.
Background technique
Engine blower is silicon oil clutch fan especially, there is larger rotary inertia and deadweight, can be subject to the effect of larger belt force simultaneously, therefore the support of supporting engines fan is just had to higher rigidity and the requirement of endurance life, therefore existing engine blower support mostly is cast-iron structure or relatively heavy heavy wall cast aluminium structure, this kind of structure is unfavorable for the light-weight design of motor, and the aluminum casting that wall thickness is larger easily produces blow hole, the defect such as loose, forms potential inefficacy hidden danger.And if to support, take loss of weight measure to make wall thickness thinner, easily cause again insufficient strength, and easily produce vibration and affect NVH performance.
Model utility content
The purpose of this utility model is to provide that a kind of quality is light, intensity is high, the engine blower support of NVH function admirable.
For achieving the above object, embodiment of the present utility model provides following technological scheme:
A kind of engine blower support, the Al-alloy parts that described engine blower support is high pressure die casting, described engine blower support has bearing hole and mounting hole, described engine blower support has loss of weight chamber, described loss of weight chamber is in the backside openings of described engine blower support but be not extended to the front of described engine blower support, and described loss of weight chamber is radial arrangement around described bearing hole.
Preferably, described loss of weight chamber size is different.
Preferably, in described bearing hole, be provided with draw-in groove.
Preferably, described loss of weight has stiffening rib between chamber, and the length of described stiffening rib is different.
Preferably, the thickness of described stiffening rib is different.
The utility model adopts high pressure die casting Al-alloy parts, thick compared with thin-walled in the situation that, have stronger rigidity and fatigue strength, lighter weight, and loss of weight chamber is radial arrangement around bearing hole, also just mean that the material between loss of weight chamber becomes radial arrangement, and bearing and fan are to rotate in a circumferential direction, this makes loss of weight chamber when obtaining weight loss effect, can not become noise diffusion source.
Further, the size in loss of weight chamber is different, the different generation that all can prevent resonance of the length of stiffening rib, thickness, the impact of having avoided thin walled structures easily to produce noise.
Accompanying drawing explanation
Fig. 1 is embodiment's of the present utility model engine blower support sectional view;
Fig. 2 is embodiment's of the present utility model engine blower bracket bottom view;
Fig. 3 is embodiment's of the present utility model engine blower support plan view.
Description of symbols in upper figure: 1, draw-in groove; 2, bearing hole; 3, loss of weight chamber; 4, stiffening rib; 5, mounting hole.
Embodiment
Therefore with reference to figure 1, the Al-alloy parts that the engine blower support in the utility model is high pressure die casting, can possess thinner wall thickness, and blow hole, the defect such as loose are less.Engine blower support has bearing hole 2 and mounting hole 5.Bearing hole 2 is for shaft connecting bearing is installed, and utilizes the 1 pair of shaft connecting bearing of draw-in groove in bearing hole 2 to carry out axial limiting.Mounting hole 5 is for being fastened to motor by engine blower support.Described engine blower support has a plurality of losss of weight chamber 3.Bottom surface with engine blower support, be the back side with the face of motor laminating, the engine blower support of take is front towards the face of external engine, as seen from Figure 1, loss of weight chamber 3 is in the backside openings of engine blower support but be not extended to the front of engine blower support, that is to say, from Fig. 2, can observe loss of weight chamber 3 but can not observe loss of weight chamber 3 in Fig. 3.
With reference to figure 2, loss of weight chamber 3 is radial arrangement around bearing hole 2, that is to say, loss of weight chamber 3 is less apart from the nearlyer width d of bearing hole 2, and apart from bearing hole 2, width d far away is larger.Meanwhile, the material between two adjacent loss of weight chambeies 3 has formed stiffening rib 4, and therefore stiffening rib 4 is also radial arrangement around bearing hole 2.And in the course of the work, bearing and fan are to rotate in a circumferential direction, this makes loss of weight chamber when obtaining weight loss effect, can not become noise diffusion source.Simultaneously, the size in each loss of weight chamber 3 is all not identical, the thickness W of every stiffening rib 4 and length L are not identical yet, this makes loss of weight chamber 3 can be avoided producing resonance with motor, fan as far as possible, and the shape of stiffening rib is various, when having increased intensity, also can prevent the generation of resonance, the impact of having avoided thin walled structures easily to produce noise.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
