Abstract
The utility model relates to a crank shaft of a slurry pump, which mainly solves the problems that the present crank shaft of the slurry pump is heavy, the transmission is not stable, and the mechanism transmission efficiency is low. The crank shaft of the slurry pump is characterized in that the crank shaft is formed by casting in one time and the entire crank shaft is hollow. The crank shaft is directly formed by casting, so as to avoid the disadvantages that the crank shaft cannot be easily processed and the precision cannot be ensured after a straight shaft is welded with an eccentric wheel in an assembly manner; as the crank shaft of the slurry pump is hollow, the weight is light and the transmission is stable, so as to improve the performance and prolong the service life of the slurry pump.
Description
Technical field
The utility model relates to a kind of main working parts in the slurry pump, relates to a kind of slurry pump bent axle specifically.
Background technique
Bent axle by gear transmission power, promotes piston with real drivening rod and crosshead and moves reciprocatingly in fluid cylinder in slurry pump, realizes the suction function of slurry pump.And the manufacturing of traditional bent axle is to form by d-axis and eccentric wheel assembly welding, because of manufacturing processes is loaded down with trivial details, has increased the difficulty of processing, and precision is difficult to guarantee, and, usually causing that transmission is not steady because weight is bigger than normal, machinery driving efficiency is on the low side, the gear wear degree is serious.
The model utility content
Bigger than normal in order to solve existing slurry pump bent axle weight, transmission is not steady, the problem that machinery driving efficiency is on the low side, and the utility model provides a kind of slurry pump bent axle.This slurry pump bent axle is because of in light weight, stable drive, thus improved pump performance and life-span.
The technical solution of the utility model is: a kind of slurry pump bent axle is characterized in that: bent axle is one-step casting moulding and whole hollow.
The beneficial effects of the utility model are: because this bent axle adopts cast-in-block form, this structure has effectively overcome d-axis and eccentric group postwelding bent axle and has been difficult for the drawback that processing, precision are difficult to guarantee; Simultaneously owing to adopting hollow-core construction to reduce bent axle weight, under the prerequisite of proof strength and rigidity, reduce the weight of component, reach at last and reduce complete machine weight and installation dimension, improve the volumetric efficiency of mechanical efficiency and pump, prolonged the working life of easily damaged parts, because complete machine weight descends thereupon, improve pump performance and life-span, possessed stable drive, advantage that noise is low simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of slurry pump bent axle;
Accompanying drawing 2 is the sectional view of accompanying drawing 1.
1,2,3,5,6-rigid bearing axle journal 4-fixed gear axle journal
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in shown in accompanying drawing 1 and the accompanying drawing 2, the fixing bearing that cooperates with frame in (1,6) axle journal place of this bent axle, the bearing that cooperates with connecting rod is fixed at (2,3,5) axle journal place, axle journal 4 places fixedly gearwheel endoporus as shown in Figure 1.Bent axle is by the engagement transferring power of pinion shaft and gearwheel, and rotation drivening rod and the crosshead promotion piston by bent axle moves reciprocatingly in fluid cylinder again, thereby realizes the suction function of slurry pump; Because this bent axle is that direct casting is reprocessed into finished product, the drawback of having avoided the difficult processing of d-axis and eccentric group postwelding bent axle, precision to be difficult to guarantee, and the process-cycle reduced to two months by original 3-4 month, had shortened the manufacture cycle, had increased working efficiency; Since crankshaft center be hollow-core construction as shown in Figure 2, weight saving 25%, under the prerequisite of proof strength and rigidity, reduced the weight of component, reach at last and reduce complete machine weight and installation dimension; This integral body open-core type bent axle has effectively overcome d-axis and eccentric group postwelding bent axle and has been difficult for the drawback that processing, precision are difficult to guarantee, owing to adopt hollow-core construction to reduce bent axle weight, complete machine weight is decline thereupon also, has improved pump performance and life-span simultaneously.
