Technical Field

[0001] The utility model relates to the technical field of engine accessories, in particular to a multi-V belt idler wheel assembly. Background Art

[0002] When the automobile engine is started, the poly-V belt has the characteristics of small transmission vibration, fast heat dissipation, stable operation, lightness, thinness and durability. Therefore, the poly-V belt idler pulley assembly composed of the poly-V belt and the poly-V belt pulley is widely used in automobile drive engine components.

[0003] At present, when a multi-V belt idler pulley assembly is working, a multi-V belt is usually used to rotate multiple multi-V belt pulleys to realize transmission operation. However, considering that the multi-V belt will slip and deviate due to insufficient tension after being used for a period of time, the multi-V belt that continues to be used at this time will easily separate from the multi-V belt pulley and fall off, which will also affect the continued operation of the multi-V belt idler pulley assembly. Therefore, a multi-V belt idler pulley assembly is proposed to address the above problem. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-V belt idler pulley assembly comprises a multi-V belt pulley drum, a left protective disc is provided on one side of the multi-V belt pulley drum, and a right protective disc is provided on the other side of the multi-V belt pulley drum, an outer sliding frame is fixedly connected to the upper and lower ends of one side end surfaces of the right protective disc and the left protective disc respectively, and a vertical connecting rod is slidably connected to the inner side of the outer sliding frame, one end of the vertical connecting rod is fixedly connected to a transverse connecting rod, and a limiting sleeve is provided on one side of the transverse connecting rod through integral molding, a limiting rolling ball is movably installed inside the limiting sleeve, an inner sliding frame is fixedly installed on the middle part of the front end of the outer sliding frame, and a protrusion is slidably connected to the inner sliding frame.

[0007] Preferably, a bearing body is clamped on the inner side of the multi-V belt pulley cylinder, and a mounting shaft is inserted into the middle position of the bearing body, and the mounting shaft is respectively inserted into the left protective plate and the right protective plate.

[0008] Preferably, the left protective plate is symmetrically arranged with the right protective plate along the vertical center axis of the multi-V belt pulley cylinder as the symmetry axis, and the outer surface of the multi-V belt pulley cylinder is provided with multi-V belt pulley teeth.

[0010] Preferably, the connection between the vertical connecting rod and the transverse connecting rod forms an "L"-shaped structure, the vertical connecting rod and the protrusion are fixedly connected, the bottom end of the vertical connecting rod is fixedly connected with a spring, and the spring is installed inside the outer sliding frame, the outer shape of the inner sliding frame is a "U"-shaped structure, and the limiting ball is arranged on one side of the bottom end of the limiting ball.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0020] A multi-V belt idler assembly comprises a multi-V belt pulley drum 1, a left protective disc 2 is provided on one side of the multi-V belt pulley drum 1, and a right protective disc 3 is provided on the other side of the multi-V belt pulley drum 1, an outer sliding frame 4 is fixedly connected to the upper and lower ends of one side end surfaces of the right protective disc 3 and the left protective disc 2 respectively, and a vertical connecting rod 5 is slidably connected to the inner side of the outer sliding frame 4, one end of the vertical connecting rod 5 is fixedly connected to a transverse connecting rod 6, and a limiting sleeve 7 is integrally formed on one side of the transverse connecting rod 6, a limiting ball 8 is movably installed inside the limiting sleeve 7, an inner sliding frame 14 is fixedly installed in the middle of the front end of the outer sliding frame 4, and the inner sliding frame 14 is slidably connected to a protrusion 16.

[0021] like Figure 1 and Figure 2 As shown, a bearing body 11 is clamped on the inner side of the multi-V belt pulley barrel 1, and a mounting shaft 10 is inserted in the middle position of the bearing body 11, and the mounting shaft 10 is respectively inserted and arranged with the left protective disc 2 and the right protective disc 3. When the multi-V belt idler assembly is installed on the frame of the automobile engine, the bearing body 11 is mainly arranged as a transition piece, and the rotation connection between itself and the mounting shaft 10 is used to facilitate the rapid connection of the entire multi-V belt idler assembly to the mounting shaft 10; the left protective disc 2 is symmetrically arranged with the right protective disc 3 along the vertical center axis of the multi-V belt pulley barrel 1 as the symmetry axis, and the outer surface of the multi-V belt pulley barrel 1 is provided with multi-V belt pulley teeth 9. When the bearing body 11 is installed into the inner side of the multi-V belt pulley barrel 1, and the left protective disc 2 and the right protective disc 3 are respectively fixed to the two side ends of the multi-V belt pulley barrel 1, The left protective plate 2 and the right protective plate 3 will provide sealing protection from the left and right side ends of the multi-V belt pulley barrel 1; the left protective plate 2 and the right protective plate 3 are respectively provided with inner chucks 12 at positions close to the bearing body 11, and a rubber gasket 13 is bonded to one side of the inner chuck 12 close to the bearing body 11, the rubber gasket 13 and the inner chuck 12 are respectively embedded in the interior of the multi-V belt pulley barrel 1, and one side of the rubber gasket 13 is fitted with one side of the bearing body 11. When the left protective plate 2 and the right protective plate 3 are respectively fixed to the two side positions of the multi-V belt pulley barrel 1, a group of inner chucks 12 will bring a group of rubber washers 13 into the interior of the multi-V belt pulley barrel 1 to extrude and limit the built-in installation of the bearing, and the close-fitting setting of a group of rubber washers 13 can also seal the installation of the bearing.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connection between the vertical connecting rod 5 and the transverse connecting rod 6 forms an "L"-shaped structure, the vertical connecting rod 5 and the protrusion 16 are fixedly connected, the bottom end of the vertical connecting rod 5 is fixedly connected with a spring 15, and the spring 15 is installed inside the outer sliding frame 4, the outer shape of the inner sliding frame 14 is a "U"-shaped structure, and the limiting ball 8 is arranged on one side of the bottom end of the limiting ball 8. As the right protective plate 3 and the left protective plate 2 are respectively installed on both sides of the multi-V belt pulley barrel 1, the "L"-shaped structure formed by the vertical connecting rod 5 and the transverse connecting rod 6 will use the rebound force generated when the spring 15 is squeezed, and the multi-V belt will be pressed down with the assistance of the limiting ball 8, thereby improving the stability of the multi-V belt when connected to the multi-V belt pulley for use.

[0023] Working process: When using the multi-V belt idler pulley assembly, first ensure that the mounting shaft 10 and the bearing body 11 are rotationally connected, and then use the mounting shaft 10 to install the multi-V belt idler pulley assembly on the frame of the automobile engine. Then, as the entire assembly is connected to multiple multi-V belt pulleys through the multi-V belt, the main drive assembly on the engine will drive the multi-V belt pulley assembly to rotate relative to the mounting shaft 10 when starting, so that the multi-V belt pulley assembly can transmit power to another set of multi-V belt pulley assemblies to facilitate the normal operation of the transmission structure. When the multi-V belt has been used for a period of time and the tension force is insufficient, the multi-V belt idler pulley assembly will use two sets of limiting balls 8 arranged on the inner edge of the guard plate to limit the multi-V belt to prevent it from slipping and deviating and falling off the multi-V belt pulley.
