Embodiment
In order to make technical problem to be solved by this invention, technological scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Please refer to Fig. 4 to Fig. 6, be the embodiment one of water pump reliability testing of the present invention with belt pulley, this belt pulley comprises pulley body 1, described pulley body is alms bowl shape, described pulley body 1 has at least one trough of belt 11 along described pulley body 1 circumferencial direction, like this, because belt pulley of the present invention is alms bowl shape, and has at least one a trough of belt along described pulley body circumferencial direction, so can simulate the stressing conditions of cooling waterpump when in running order truly, thereby improve the accuracy of testing result widely.Below describe in detail.
In order to control the point of action of belt on belt pulley more accurately, so that the stress of simulated engine cooling waterpump more accurately, described trough of belt 11 is a V-shaped groove, and trough of belt 11 can only be established a V-shaped groove.Described trough of belt 11 is positioned on the described pulley body 1, near a side of described belt pulley opening, and position and described water pump when in running order of described trough of belt 11 on described pulley body 1, the water pump belt is to the force application location correspondence of Water-pump belt wheel.Certainly, trough of belt 11 also can be other shapes, as circular groove or dovetail groove etc.
Certainly, when 11 of troughs of belt adopt a V-shaped groove, requirement of strength to belt is higher, at this moment, the quantity of described trough of belt 11 is to be multiple tracks, like this, the belt that drives belt pulley can be poly Vbelt 28 (please refer to Fig. 9), in this case, the active force of 28 pairs of belt pulleys of poly Vbelt is concentrated not as only adopting a V-shaped groove, but its point of action roughly equiv to the belt pulley active force is the middle part that is positioned at poly Vbelt 28.Belt in the present embodiment is a poly Vbelt.
Because in test process, belt is lax easily, for preventing the poly Vbelt slippage, in the described multiple tracks trough of belt 11 in the outside of outermost one trough of belt and the described multiple tracks trough of belt 11 inboard of one the most inboard trough of belt extend a blocked part 12 respectively.
For realizing installation, on the diapire of described alms bowl shape pulley body 1, be provided with some pilot holes 13 to the present embodiment belt pulley.In the present embodiment, the quantity of pilot hole 13 is 4 and is distributed on the diapire of pulley body 1.
For ease of installation, on the diapire of described alms bowl shape pulley body 1, also be provided with some and described pilot hole 13 auxiliary pilot hole 14 at interval to the present embodiment belt pulley.Because belt pulley need be installed on the water pump wheel hub, and wheel hub rotates, this makes the installation of belt pulley have certain difficulty, therefore needs to adopt auxiliary mounting hole 14.During installation, can use one or more pole to penetrate, and replace on the pump housing,, thereby create conditions for installing with the rotation of restriction wheel hub from auxiliary pilot hole 14.In addition, auxiliary pilot hole 14 also has the effect that alleviates belt pulley weight.
Please refer to Fig. 7 and Fig. 8, be the embodiment two of water pump reliability testing of the present invention with belt pulley, compare with embodiment one, the size of present embodiment is less, the position of trough of belt 11 is also different with embodiment one in the present embodiment, and this is because the water pump of different size has different stress (being that force bearing point and stressed size can be inequality to some extent) in practical work process.And on the other hand, the stressed size of belt pulley and cornerite (cornerite, be meant band and belt wheel contact arc right central angle) angle relevant, the force bearing point of belt is relevant with the position of trough of belt 11 on pulley body 1.Therefore, in order to realize real simulation, need to select suitable belt pulley to the water pump stressing conditions.Because the size of present embodiment is less, the pilot hole 13 on it and the quantity of auxiliary pilot hole 14 all can be less than embodiment one.
Please refer to Fig. 9, be a preferred embodiment of water pump reliability testing test stand of the present invention, this water pump reliability testing test stand comprises power-driven system, pipe-line system, water pump mounting and clamping system, measurement and display control program.
In the present embodiment, described power-driven system comprises motor 21, removably connected with described test stand by dibit belt pulley 22 that described motor 21 drives and two and in order to the belt pulley 23,24 of driving water pump, belt pulley 23,24 can have different technical parameters so that simulate the stress of different water pumps, its structure is same as the previously described embodiments, does not give unnecessary details at this.Certainly, the quantity of belt pulley can also be one or more.
In the present embodiment, described water pump mounting and clamping system comprises water pump support 25, in order to realize accurate location to water pump, also can between test stand water pump support 25 and water pump, establish base plate 26 is installed, realize cooperating between water pump wheel hub 27 and the dibit belt pulley 22 by the installation base plate 26 of selecting different-thickness.
Like this, the water pump reliability testing test stand of present embodiment just can be realized the test job to two water pumps simultaneously.And can realize real simulation to the water pump stress by the belt pulley of selecting to have the different technologies parameter (promptly having different troughs of belt position and size).Thereby improved the compatibility of water pump reliability testing test stand greatly.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
