Embodiment
[0027] The utility model will be further explained in detail in combination with specific embodiments and by referring to the drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the utility model and its applications.
[0028] With reference to the following drawings, non-limiting and non-exclusive embodiments will be described, in which the same reference numerals indicate the same parts, unless otherwise specifically indicated.
[0029] A multifunctional fan shaft mounting support, as shown in Figures 1-4 The support is divided into front and back, including integrally formed fan shaft seat 1, air compressor flange 2 and steering pump flange 3, wherein first through hole 101, second through hole 201 and third through hole 301 are respectively arranged through the front and back of the support. The fan shaft seat 1 protrudes from the front of the support, and a plurality of first recesses 102 recessed from the fan shaft seat 1 are arranged on the side arm of the first through hole 101, and the first through hole 101 and the first recess 102 are matched with the fan shaft to fix the fan shaft, specifically, the number of the first recess 102 is eight, which is evenly distributed on the side wall of the first through hole 101, in some other examples, other number of first recesses 102 can also be arranged according to different models of fan shaft, as long as it is convenient to install the fan shaft, the specific number is not limited. The air compressor flange 2 is arranged on the left side of the fan shaft seat 1, including a circular recess 202 recessed inward from the back of the support, which is coaxial with the second through hole 201;As Figure 2 And 3As shown, an oil return channel 4 is arranged below the air compressor flange 2 for returning oil to the gear chamber. The oil return channel 4 starts from the left side wall of the bracket and ends at the oil return hole 5. The oil return hole 5 is semi-closed and penetrates through the back of the bracket. In other words, the oil return hole 5 is open at the back of the bracket and closed at the front of the bracket. In actual use, a plug is arranged at the oil return channel 4 on the left side wall of the bracket to prevent oil from flowing out of the left side of the bracket. As shown in Figure 2 and 3 As shown, a slant hole 6 is arranged on the groove wall of the circular groove 202 and communicates with the oil return channel 4. In this way, oil can flow from the air compressor flange 2 to the oil return channel 4 through the slant hole 6 and then return to the gear chamber through the oil return hole 5. This can effectively avoid waste of oil and recycle the oil. The steering pump flange 3 is arranged below the air compressor flange 2 and connected to the steering pump through the third through hole 301.
[0030] The mounting bracket mentioned above integrates the fan shaft seat 1, the air compressor flange 2 and the steering pump flange 3 into one bracket, so that the overall structure is compact and firm, multiple parts are integrally formed, the manufacturing cost and installation difficulty of the parts are reduced to a certain extent, and the efficiency is improved. The oil return channel 4 is arranged on the bracket, so that oil can flow from the air compressor flange 2 to the oil return channel 4 through the slant hole 6 and then return to the gear chamber through the oil return hole 5. This can effectively avoid waste of oil and recycle the oil.
[0031] In some examples of the embodiment, as shown in Figure 1 and 4 As shown, a plurality of idler shaft mounting lugs 7 are arranged near the fan shaft seat 1 to facilitate installation of the idler 12. In this example, the number of idler shaft mounting lugs 7 is three, two of which are arranged side by side below the fan shaft seat 1, and the other is arranged on the right side of the fan shaft seat 1.
[0032] In some examples of the embodiment, as shown in Figure 1 As shown, the side wall of the oil return channel 4 protrudes from the front of the bracket, which can serve as a hollow reinforcing structure to strengthen the strength and rigidity of the bracket.
[0033] In some examples of the embodiment, as shown in Figure 1 and 4 As shown, a recess 8 is arranged between the air compressor flange 2 and the steering pump flange 3. The recess 8 is recessed from the right side of the bracket to the left side of the bracket. The recess 8 is used to provide space for the automatic tensioning wheel 13 in the wheel train, so as to arrange the entire wheel train compactly, save space, reduce the size of the entire engine, and increase the environment available for the engine.
[0034] In some examples of the embodiment, as shown in Figure 2As shown, a fourth through hole 9 is arranged in the extending direction of the inclined hole 6, and the fourth through hole 9 penetrates to the recess 8. It can be understood that the fourth through hole 9 is a process hole, so as to facilitate the forming of the fourth through hole 9, simplify the processing process, and reduce the processing cost. In specific use, a plug is arranged at one end of the fourth through hole 9 away from the air compressor flange 2, so as to avoid oil from flowing out of the fourth through hole 9.
[0035] In some examples of the embodiment, as shown in Figure 1 As shown, a plurality of reinforcing ribs 10 are arranged around the fan shaft seat 1, the air compressor flange 2, the steering pump flange 3, and the idler shaft mounting bracket 7, respectively, so as to improve the overall strength of the bracket.
[0036] In some examples of the embodiment, as shown in Figure 1 As shown, a plurality of hollows 11 are arranged between the reinforcing ribs 10 around the fan shaft seat 1, so as to reduce the weight of the bracket as much as possible while ensuring the overall structural strength of the bracket.
[0037] Those skilled in the art will recognize that numerous modifications can be made to the above description without departing from the scope of the embodiments and examples.
[0038] While there have been described herein the exemplary embodiments of the present application, those skilled in the art will recognize that changes can be made within the scope of the present application without departing from the spirit thereof. Further, it is not intended that the present application be limited to the particular embodiment described herein, but that the application will include all embodiments falling within the scope of the application.
