In order to solve the problems of the technologies described above, the utility model comprises rear power taking housing and rear power taking flywheel casing, on described rear power taking flywheel casing, flywheel is installed, on described rear power taking housing, driving gear is installed, its structural feature is on described driving gear, to be engaged with successively intermediate gear and driven gear from bottom to top, the engagement of described driving gear and intermediate gear, described intermediate gear meshes with driven gear, described driven gear be positioned at crankshaft axis directly over; Splined shaft on described driven gear is connected with the rear power taking output flange being arranged on rear power taking housing; Described intermediate gear is arranged on rear power taking housing by intermediate gear shaft; Described rear power taking housing is provided with the lubricant pipe assembly being communicated with body main oil gallery, and the end of described lubricant pipe assembly is provided with nozzle, the inwall setting of power taking housing and rear power taking flywheel casing after described nozzle correspondence.
Between the crankshaft installed hole of described flywheel and rear power taking flywheel casing, be equipped with into oil seal.
Between described rear power taking flywheel casing and the splined shaft of driven gear, oil seal is housed out.
The corresponding driven gear place, outside of described rear power taking housing is provided with gear cap.
Described lubricant pipe assembly is fixed on the sidepiece of rear power taking housing by pipe clamp, described lubricant pipe assembly is communicated with body main oil gallery by hollow bolt.
Compared with prior art the utlity model has following advantage: driven gear is arranged on the middle part of rear power taking housing, because power taking delivery outlet is after this positioned at directly over crankshaft axis, adapt with the rear power taking position of concrete mixer; Cancel oil hydraulic pump delivery outlet, reduce a gear and corresponding bearing, reduced the complexity of structure, improved reliability; Rear power taking output Placement be driven gear itself with splined shaft be connected with rear power taking output flange, saving component, simplification installation procedure, makes structure simpler; Lubricant pipe assembly is sprayed onto lubricant oil on the inwall of rear power taking housing and rear power taking flywheel casing, be splashed to again on each gear and corresponding rolling bearing, reduce the impact of lubricant oil to each parts, improve lubrication effect, in sum, the utility model is adapted to concrete mixer and uses, and have simple in structure, the beneficial effect of high lubricating effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Fig. 1 removes the rear view after flywheel casing;
Fig. 3 be in Fig. 1 A-A to sectional view.
Embodiment
With reference to accompanying drawing, this diesel engine real power takeoff device comprises rear power taking housing 1 and rear power taking flywheel casing 8, and rear power taking housing 1 and rear power taking flywheel casing 8 are bolted and are integrated.On rear power taking flywheel casing 8, flywheel is installed, on rear power taking housing 1, driving gear 2 is installed, on driving gear 2, be engaged with successively intermediate gear 3 and driven gear 4 from bottom to top, driving gear 2 and intermediate gear 3 engagements, intermediate gear 3 and driven gear 4 engagements.Driven gear 4 be positioned at bent axle 11 center lines directly over, because power taking delivery outlet after this is also positioned at the intermediate portion, top of rear power taking housing 1, adapt with the rear power taking position of concrete mixer; Splined shaft on driven gear 4 is connected with the rear power taking output flange 12 being arranged on rear power taking housing 1, rear power taking output flange 12 is connected with concrete mixer rear power takeoff, thereby the power of bent axle 11 outputs is passed to concrete mixer by the splined shaft on driven gear 4.Intermediate gear 3 is arranged on rear power taking housing 1 by intermediate gear shaft 6.Between rear power taking flywheel casing 8 and the splined shaft of driven gear 4, oil seal 10 is housed out, prevents that dust from entering, oil leakage, the Packed effect of tool.Between bent axle 11 mounting holes of flywheel and rear power taking flywheel casing 8, be equipped with into oil seal 7, prevent that dust from entering, oil leakage, the Packed effect of tool.Corresponding driven gear 4 places, outside of rear power taking housing 1 are provided with gear cap 13, have the effect that seals and prevent leakage of oil.
