Embodiment
Describe the present invention in detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the externally-mounted accessory drive mechanism of present embodiment comprises support 1, Combined belt wheel 2, circlip 3, bearing 4, bolt backing plate 5 and bolt 6, can increase lengthened plate 7 in case of necessity.
As shown in Figure 3, the support 1 of accessory drive mechanism mainly comprises structures such as bracket base 8, support semiaxis 9 and center screw 10, the structure of described support 1 can by the cast blank of support implemented car, mill, mechanical processing technique such as brill is achieved.Described support semiaxis 9 realizes and the installation that cooperates of Combined belt wheel 2 that by rolling bearing 4 described center screw 10 can screw with bolt 6 and by bolt backing plate 5 Combined belt wheel 2 is fastened on the support 1.Described bracket base 8 can be fixedly mounted on whole driving mechanism on the internal combustion engine main body by the installation unthreaded hole on it.
As shown in Figure 4, the Combined belt wheel 2 of described accessory drive mechanism mainly is provided with the centralized positioning counterbore 15 of poly Vbelt wheel race structure 11, circlip mounting groove 12, flange arrangement 13, waist shaped hole 14 and taper parting face.All structures of described Combined belt wheel 2 can by the cast blank spare of Combined belt wheel implemented car, mill, process for machining such as brill realizes; Also can realize combination by technologies such as welding again by manufacturing experimently poly Vbelt wheel race structure and flange arrangement respectively.Described poly Vbelt wheel race can require according to the difference of train scheme to change its wedge groove number, even make V belt wheel or flat wheel, receives the moment of torsion of driving wheel output by corresponding band type of belt drive.Described circlip mounting groove 12 can be adjusted processing according to the different circlips of selecting for use 3, described waist shaped hole 14 is arranged on the circumferential of flange, this hole can be precast hole, also can form by expanding hinge, can realize with lengthened plate 7 or is driven docking of attachment flange by this waist shaped hole 14.The centralized positioning counterbore 15 of described taper parting face can pass through the lathe tool moulding.Described taper shape of hole wall can be realized radially preposition with the location axle head of different-diameter, so that the waist shaped hole 14 on the flange arrangement 13 docks smoothly with the flange that docks lengthened plate or be driven annex.
The support 1 of present embodiment and Combined belt wheel 2 all can be casting back machining and form, circlip 3, bearing 4 and bolt 6 all can be selected standard piece for use, it is convenient to make whole accessory drive mechanism can concentrate trial-production, assembly to supply like this, more helps simplifying assembly technology, reduces purchase cost.Make entire product have the stronger market competitiveness.
