Abstract
The utility model provides a fan belt pulley support which is provided with a bearing via hole. A positioning boss is disposed on one side, close to a cylinder block, in the bearing via hole. The utility model further provides a fan belt pulley mounting structure and an engine which adopt the fan belt pulley support. The fan belt pulley support, the fan belt pulley mounting structure and the engine have the advantage that mounting reliability of a fan belt pulley is increased.
Description
Technical field
The utility model relates to engine art, is specifically related to the fan belt wheel support of motor and fan belt wheel mounting structure, motor.
Background technique
Engine mechanical formula fan is common and water pump is integrated, is driven by belt pulley by bent axle.Fan and water pump are integrated because axial force is large, easily cause the inefficacy of water pump bearing, water seal, and NVH is poor, and fan cooled performance is not high yet.
In order to meet the requirement of engine cooling performance, NVH, adopt independently fan pulley bracket component to carry out the installation of fan, and adopt shaft connecting bearing at present, can make stable drive, reduce noise.With reference to figure 1, in the fan belt wheel mounting structure of prior art, shaft connecting bearing 2 and fan pulley land 3 interference fit, then insert shaft connecting bearing 2 in the bearing via hole 11 of fan belt wheel support 1 and both interference fit.The interior side near engine cylinder-body of bearing via hole 11 is installed end ring 4, away from a side of engine cylinder-body, end ring 5 is installed, thereby is realized the axially locating of shaft connecting bearing 2 in bearing via hole 11.But end ring 4, owing to will being subject to responsive to axial force and the engine luggine of shaft connecting bearing 2, easily damages and loses locating function.
Model utility content
The purpose of this utility model is to provide one fan belt wheel support and fan belt wheel mounting structure more reliably, and embodiment of the present utility model provides following technological scheme for this reason:
A kind of fan belt wheel support, has bearing via hole on the wheel support of described fan belt, and the side near cylinder body in described bearing via hole has positioning boss.
Preferably, described positioning boss is right-angled triangle, and the hypotenuse of described right-angled triangle is near described cylinder body.
Preferably, between the starting point of described hypotenuse and the cylinder body attachment face of described fan belt wheel support, there is gap.
A kind of fan belt wheel mounting structure, comprise fan belt as above wheel support, fan pulley land, shaft connecting bearing, end ring, described shaft connecting bearing and described bearing via hole interference fit are also located described shaft connecting bearing and described fan pulley land interference fit by described positioning boss and described end ring.
A kind of motor, the fan pulley of described motor is to adopt fan belt as above wheel mounting structure to be installed on cylinder body.
In the utility model, in the wheel support course of working of fan belt, in bearing via hole, the side near cylinder body has been reserved positioning boss, shaft connecting bearing is located by positioning boss in the one end near engine cylinder-body, the other end is located by end ring, and this makes structure more reliable.
Further, positioning boss is right-angled triangle, and hypotenuse is near cylinder body, while needing to adjust the axial position of shaft connecting bearing, being easily to realize near adding back-up ring in a side bearing via hole of cylinder body.
Further, the gap between hypotenuse starting point and the cylinder body attachment face of positioning boss has ensured that positioning boss itself can not wear and tear because of engine luggine, thereby ensures the positioning precision of fan pulley.
Brief description of the drawings
Next in connection with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is fan belt of the prior art wheel mounting structure cross-sectional schematic;
Fig. 2 is embodiment's of the present utility model fan belt wheel mounting structure cross-sectional schematic;
Fig. 3 is the partial enlarged drawing of the A part in Fig. 2.
Description of symbols in upper figure: fan belt wheel support 1, shaft connecting bearing 2, fan pulley land 3, end ring 4, end ring 5, bearing via hole 11, positioning boss 12, fan belt wheel support 10, shaft connecting bearing 20, fan pulley land 30, end ring 50, bearing via hole 110, positioning boss 120, cylinder body attachment face 130.。
Embodiment
With reference to figure 2, in the present embodiment, cancel end ring 4, the substitute is at the interior positioning boss 120 near engine cylinder-body one side of bearing via hole 110, positioning boss 120 is reserved in the course of working of fan belt wheel support 10, although this has improved the difficulty of processing of bearing via hole 110, positioning boss 120 has brought locating effect more reliably.When mounted, after shaft connecting bearing 20 and fan pulley land 30 interference fit, shaft connecting bearing 20 is inserted to bearing via hole 110 end ring 50 is installed again.Like this, shaft connecting bearing 20 is to coordinate location by positioning boss 120 and end ring 50, simpler.And as preferred, as can be seen from Fig. 2, positioning boss 120 is right-angled triangle, the hypotenuse of this right-angled triangle is more near engine cylinder-body, the hypotenuse that is positioning boss 120 is that the axial direction from start oblique bearing via hole 110 near engine cylinder-body one side tilts, such advantage is in the time need to adjusting the axially locating size of shaft connecting bearing 20, is eaily at the interior interpolation pad of a side bearing via hole 110 or back-up ring near engine cylinder-body.
With reference to figure 3, after structure in Fig. 2 is installed on engine cylinder-body, the cylinder body attachment face 130 of fan belt wheel support 10 and cylinder body laminating, the hypotenuse starting point B of positioning boss 120 starts from cylinder body attachment face 130, but and there is gap d between cylinder body attachment face 130, avoid like this positioning boss 120 to be polished by cylinder body due to engine luggine, ensured positioning intensity and the precision of shaft connecting bearing 20.
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 claim, those of ordinary skill in the art can easily carry out equivalence to it and replace or revise, but do not leave essence design of the present utility model and scope.
