Abstract
The utility model relates to a lubricating pump with power take off mechanism, comprising a pump body, a pump base, a drive shaft, a driven shaft, a driving gear, and a driven gear which is engaged with the driving gear. The pump body and the pump base which are connected are fixed on a crankcase; a main fulcrum shaft is supported on the pump body by a single point, the inner end of the main fulcrum shaft is connected with the driving gear, and the outer end of the main fulcrum shaft is connected with a chainwheel. Tow points of the driven shaft are supported on the bearing parts of the pump body and the pump base, one end of the driven shaft is extended out of the cavity of the pump body, and a flat rectangular drive binding site is arranged at the extending end. The lubricating pump with power take off mechanism is characterized in that one end of the driven shaft is extended out of the enclosed pump body, so that the extending end can be connected with the drive binding site, the structure can be reasonable and compact, and power can be taken off by the pump.
Description
Technical field
The utility model belongs to the motorcycle engine technical field, relates in particular to a kind of oil pump with power take-off mechanism.
Background technique
Machine oil pump for motor generally is installed in float chamber side in the crankcase, by actuation gear on the bent axle or valve cam chain drive, two kinds of structures of gear type or rotator type is arranged.A kind of quantitative oil pump that gear type oil pump is made up of two pitch wheels, the number of teeth of driving and driven gear is identical, by the gear meshing line gear and pump cover is formed sealed mode pump oil structure.In this sealed mode oil pump structure, the driven shaft that connects driven gear is supported in the airtight space, does not connect with other parts, and the function of being born only is the supporting driven gear.This single structure has not only taken the confined space of oil pump, and has wasted the power function of driven shaft.How utilizing the power transmission function of driven shaft, make the driving structure of oil pump more become reasonable, compact, thereby dwindle the volume of motor, is very favourable for the improved properties of motorcycle.
Summary of the invention
The utility model above-mentioned purpose is achieved through the following technical solutions:
A kind of oil pump with power take-off mechanism, it comprises the pump housing, pump seat, driving shaft, driven shaft, driving gear and with the driven gear of its engagement, the pump housing is connected with pump seat and is fixed in crankcase, the driving shaft single point supporting is on the pump housing, the inner driving gear that connects, the outer end connects sprocket wheel, it is characterized in that 2 of driven shafts are supported on the bearing portion of the pump housing and pump seat, and an end of axle extends to outside the pump chamber.
Described oil pump is characterized in that in the inboard of driven shaft driven gear being set, and the extending end of driven shaft is provided with the driving connecting part of a deltiod.
The utility model makes the inboard of driven shaft connect driven gear by driven shaft is extended outside the oil pump obturator, makes extending end can connect the driving connecting part of a deltiod, reaches rational in infrastructure, compact purpose.When driving wheel on the driving shaft and driven gear engagement rotation, can drive the driving connecting part of driven shaft outer end, reach oil pump and in pump oil, realize the power transmission function.
Description of drawings
Fig. 1 is the utility model structural representation.
In the diagram: the pump housing (1), pump seat (2), cover plate (3), driving shaft (4), driven shaft (5), driving gear (6), driven gear (7), sprocket wheel (8), bearing portion (9), pin (10) drives connecting part (11), chain (12).
The oil pump pump housing (1) is integral by screw attachment with pump seat (2) and is fixed on the crankcase, and the pump housing (1) is integral by screw attachment with cover plate (3).In the bearing portion (9) of the pump housing (1), inner the outer end connects with sprocket wheel (8) by pin (10) driving shaft (4) by pin (10) connection driving gear (6) by bearing portion single point supporting, and nut is used for axial restraint sprocket wheel (8).Driven shaft (5) is supported on the bearing portion (9) of the pump housing (1) and pump seat (2) by 2 in its bearing portion, and driven shaft connects with driven gear (7) with pin (10), and makes itself and the synchronous rotation of driven gear (7).One end of driven shaft (5) extends outside the pump chamber, is provided with the driving connecting part (11) of a deltiod at extending end, in order to connect other power-transmitting part.Oil pump drives chain (12) by bent axle and drives.
Embodiment
Embodiment of the present utility model is as follows:
The gear type oil pump pump housing is installed on a side of crankcase, and the bent axle of rotation drives the driving shaft sprocket wheel by chain, and sprocket wheel drives the driving gear running and meshes with driven gear.The driving shaft single point supporting is in the bearing portion of the pump housing, and the inner of driving shaft connects driving gear, and the outer end connects driven sprocket, initiatively, driven sprocket keeps rotating synchronously with driving shaft.Driven shaft is not supported on the bearing portion of the pump housing and pump seat by two bearing part, connects driven gear and keeps rotating synchronously with driven gear with pin.One end of driven shaft extends pump chamber, extends the driving connecting part that the end is provided with a deltiod, is used for the parts of external driving water pump transmission.
When the engine oil pump work, bent axle rotates and drives sprocket wheel (8) by chain (12) and rotates, sprocket wheel (8) rotates driving shaft (4) by pin (10) synchronously, driving shaft (4) drives driving gear (6) by pin (10), driving gear (6) engagement drives driven gear (7), driven gear (7) drives driven shaft (5) by pin (10), and driven shaft (5) drives the water pump transmission part by the driving connecting part (11) of the deltiod of end, realizes power output.
Claims (2)
1. oil pump with power take-off mechanism, it is characterized in that comprising the pump housing, pump seat, driving shaft, driven shaft, driving gear and with the driven gear of its engagement, the pump housing is connected with pump seat and is fixed in crankcase, the driving shaft single point supporting is on the pump housing, the inner driving gear that connects, the outer end connects sprocket wheel, it is characterized in that 2 bearing portions that are supported on the pump housing and pump seat of driven shaft, and an end of axle extends to outside the pump chamber.
2. oil pump according to claim 1 is characterized in that in the inboard of driven shaft driven gear being set, and the extending end of driven shaft is provided with the driving connecting part of a deltiod.
