As a further improvement on the present invention, on the mounting hole inwall of described belt pulley, flywheel, be equipped with annular high pressure oil groove, on described belt pulley, flywheel, be equipped with the oilhole of suppressing being communicated with annular high pressure oil groove.
As a further improvement on the present invention, the hydraulic fluid port of suppressing oilhole on described belt pulley, flywheel seals with dustproof plug.
As a further improvement on the present invention, on the end face of described bent axle front and back ends, have threaded central aperture, on the end face of bent axle front and back ends, connect front end-stopping plate, rear end-stopping plate by baffle plate bolt respectively, described front end baffle limiting belt pulley, described rear end baffle limiting flywheel.
As a further improvement on the present invention, between described front end crankshaft gear, rear end crankshaft gear and bent axle, being interference fit is connected.
compared with prior art, advantage is in the present invention:bent axle output mechanism of the present invention is simple in structure, compact, easy for installation, spends to be full of to be connected between belt pulley, flywheel and bent axle by high-voltage cone, be connected firmly, and good reliability, output accuracy is high and stable; Vibration damper is arranged on belt pulley and forms assembly, makes belt pulley transmission working stability, the smooth working more of whole mechanism.
Brief description of the drawings
fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the bent axle output mechanism in embodiment is mainly made up of component such as bent axle 1, the first short locating stud 2, crankshaft front end gear 3, the first long locating stud 4, belt pulley 5, vibration damper 6, lock bolt 7, front end-stopping plate 8, baffle plate bolt 9, dustproof plug 10, flywheel 13, rear end-stopping plate 14, the second long locating stud 15 crankshaft rear end gears 16 and the second short locating studs 17.
Placement between described belt pulley 5 and bent axle 1 as shown in Figure 1, described bent axle 1 front end is made as tapered end, the mounting hole of described belt pulley 5 is made as cone shape hole, the tapering of belt pulley 5 mounting hole internal surfaces is consistent with the tapering of bent axle 1 front end outer surface, and bent axle 1 front end is spent to be full of for high-voltage cone with belt pulley 5 and is connected.The connection of this kind of mode, can guarantee to be connected firmly between belt pulley 5 and bent axle 1, reliably, and taper fit precision is high, has ensured the precision and stability that belt pulley 5 is exported.
The mounting hole inwall of described belt pulley 5 is provided with annular high pressure oil groove 12, described belt pulley 5 be provided be communicated with annular high pressure oil groove 12 suppress oilhole 11.After belt pulley 5 is in place, dismantle as needed, must from suppressing oilhole 11, hydraulic oil be squeezed into annular high pressure oil groove 12 with hydraulic press, utilize hydraulic buckling power that belt pulley 5 is extruded; In addition, the hydraulic fluid port of suppressing oilhole 11 on described belt pulley 5 seals with dustproof plug 10, suppresses oilhole 11 to prevent that the foreign matters such as dust from entering.
On the end face of described bent axle 1 front end, have threaded central aperture, end-stopping plate 8 before connecting by baffle plate bolt 9 on the end face of bent axle 1 front end, the spacing belt pulley 5 of described front end-stopping plate 8 plays safety guarantee effect in the time of dismounting belt pulley 5.
As shown in Figure 1, the Placement between the Placement between described flywheel 13 and bent axle 1 and belt pulley 5 and bent axle 1 is identical, adopts high-voltage cone to spend to be full of to be connected between flywheel 13 and bent axle 1, ensures the reliability of transmitting; Flywheel 13 utilizes hydraulic buckling power to pull down from bent axle 1; The spacing flywheel 13 of end-stopping plate 14 after bent axle 1 rear end utilizes, ensures the Security of dismounting.
As shown in Figure 1, described vibration damper 6 is located by internal diameter seam, is locked on belt pulley 5 by lock bolt 7.Because vibration damper 6 is not to be directly connected on bent axle 1 or on the elongation line of whole bent axle output mechanism, bent axle 1 drives belt pulley 5 and then drives vibration damper 6, when bent axle 1 and flywheel 13 are played to damping effect, also to its key effect of the transmission stability of belt pulley 5; In addition, vibration damper 6 is connected to the complexity that has also reduced bent axle 1 structure on belt pulley 5, has controlled the effective length of bent axle 1, has improved the intensity of bent axle output mechanism.
