In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of three-plunger reciprocating Pumpp with reduction gears mechanism, comprise motor, cabinet and the coupling setting within it, gear shaft-cup, roller bearing, gear shaft, gear and bent axle, described motor is connected with gear shaft by coupling, described gear shaft is arranged on cabinet inside by roller bearing and gear shaft-cup, two gear engagements on described gear shaft, two described gears are coaxially arranged on bent axle.
More specifically, described bent axle is connected by double-row self-aligning roller bearing with cabinet.
More specifically, described gear shaft-cup is threaded with cabinet.
More specifically, on described gear shaft end, be connected with gear pump.
More specifically, be provided with bearing shell asphalt channel and bearing shell asphalt channel mouth on described bent axle, described gear pump is connected with pressure lubrication oil circuit by lubricant pipe, and described pressure lubrication oil circuit is connected with bearing shell asphalt channel and bearing shell asphalt channel mouth.
The beneficial effects of the utility model are:
The utility model motor is directly connected with gear shaft by coupling, gear shaft and gear mesh at cabinet inside, gear is on bent axle, thereby form diclinic reduction gears mechanism, save installing space, reduced the volume of pump, greatly reduced manufacture cost, improved transmission efficiency and transmission accuracy, pump running is more steady.In bent axle, be provided with bearing shell asphalt channel and bearing shell asphalt channel mouth simultaneously, lubricating gear pump is directly connected on gear shaft, pressure lubrication oil circuit is connected with gear pump by lubricant pipe, can make like this lubricant oil by gear pump, lubricant pipe, pressure lubrication oil circuit, enter into the bearing shell asphalt channel bearing shell asphalt channel mouth of bent axle, in the bearing shell finally entering and connection rod set, be lubricated, greatly increased the working life of bearing shell.
Accompanying drawing explanation
Fig. 1 is that the utility model is with the three-plunger reciprocating Pumpp structural representation of reduction gears mechanism
In figure, motor 1, coupling 2, gear shaft-cup 3, roller bearing 4, gear shaft 5, gear 6, bent axle 7, cabinet 8, lubricating gear pump 9, bent axle end cap 10, lubricant pipe 11, pressure lubrication oil circuit 12, bent axle back-up ring 13, double-row self-aligning roller bearing 14, bearing shell asphalt channel 15, bearing shell asphalt channel mouth 16, bearing shell 17, connection rod set 18.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model is comprised of motor 1, coupling 2, gear shaft-cup 3, roller bearing 4, gear shaft 5, gear 6, bent axle 7, cabinet 8, lubricating gear pump 9, bent axle end cap 10, lubricant pipe 11, pressure lubrication oil circuit 12, bent axle back-up ring 13, double-row self-aligning roller bearing 14, bearing shell 17, connection rod set 18 for the diclinic gear reducer of reciprocating pump.
Described motor 1 is directly connected with gear shaft 5 by coupling 2, the mode that coupling 2 connects by interference is connected with gear shaft 5, and gear shaft 5 is arranged on the inside of cabinet 8 by roller bearing 4 and gear shaft-cup 3, gear shaft-cup 3 is threaded connection on cabinet 8, the gear teeth on gear shaft 5 and two gears 6 are in the inner engagement of cabinet 8, thereby form diclinic reduction gears mechanism, saved installing space, reduced the volume of pump, greatly reduce manufacture cost, improved transmission efficiency and transmission accuracy, pump running is more steady; The mode that gear 6 connects by interference is directly installed on bent axle 7, can eliminate like this stress of gear 6 and bent axle 7 generations and concentrate, and improves the reliability of pump.Bent axle 7 adopts double-row self-aligning roller bearing 14 to be connected with 8 of cabinets, can carry the crooked angular distortion producing by auto-compensation bent axle 7, thus the working life of improving diclinic gear.Wherein gear shaft 5 ends are connected with lubricating gear pump 9, on bent axle 7, be provided with bearing shell asphalt channel 15 and bearing shell asphalt channel mouth 16, gear pump 9 is connected with pressure lubrication oil circuit 12 by lubricant pipe 11, and described pressure lubrication oil circuit 12 is connected with bearing shell asphalt channel 15 and bearing shell asphalt channel mouth 16.Can make like this lubricant oil by gear pump 9, lubricant pipe 11, pressure lubrication oil circuit 12, enter into bearing shell asphalt channel 15 and the bearing shell asphalt channel mouth 16 of bent axle 7, in the bearing shell 17 finally entering and connection rod set 18, be lubricated, greatly increased the working life of bearing shell.
During device operation, motor 1 rotates by coupling 2 band gear shafts 5, and the gear teeth on gear shaft 5 and two gears 6 engagements are rotated, deceleration strip moving gear 6 and bent axle 7 rotate, and bent axle 7 is due to the eccentric structure of self, thereby drive link group 18 is done linear reciprocating motion.In forced lubricating system, the direct driven gear pump 9 of gear shaft 5 is done rapid circular movement, make lubricant oil produce pressure and flow, in the bearing shell 17 and connection rod set 18 finally entering by the bearing shell asphalt channel 15 in lubricant pipe 11, pressure lubrication oil circuit 12, bent axle 7 and bearing shell asphalt channel mouth 16, thereby reach the object of lubrication shaft bushing 17 and slideway.
