Abstract
The utility model discloses a five-crank four-support structure for a reciprocating pump. The five-crank four-support structure comprises a base (1) and a crankshaft (2), a first bearing (3) and a fourth bearing (4) are arranged on two sides of a casing of the base (1), two ends of the crankshaft (2) are respectively connected with the first bearing (3) and the fourth bearing (4), a second bearing (5) and a third bearing (6) which are used for supporting the crankshaft (2) are arranged in the casing of the base (1), the crankshaft (2) is connected with a first connecting rod (7), a second connecting rod (8), a third connecting rod (9), a fourth connecting rod (10) and a fifth connecting rod (11), and the five connecting rods are arranged on the crankshaft at the same internal. On the premise of the same transmission power and the same flow pressure, the reciprocating pump using the five-crank four-support structure has the advantages of simple structure, uniform and harmonious stress on different components, capability of realizing high-speed operation, small overall size, light weight, reliable structure, convenience in maintenance and reduction of manufacturing cost and use cost.
Description
Technical field
The utility model belongs to the pump technical field, relates to a kind of five connecting levers, four supporting structures that are used for reciprocating pump concretely.
Background technique
The existing crankshaft support structure that is used for reciprocating pump will have dual mode: the full supporting structure of the crank of bent axle and 2 supporting structures.
1, the full supporting structure of the crank of bent axle, as shown in Figure 2: bent axle 12 is fixed on the sliding bearing 13, sliding bearing 13 is on support 14, connecting rod 15 is on the crank pin of bent axle 12, the corresponding sliding bearing of each crank, this complex structure, it is big that difficulty is adjusted in installation, the requirement on machining accuracy height, stability is bad.Also need to add thrust-bearing 16 and bear axial force.
2,2 supporting structures, as shown in Figure 3: bent axle 17 is fixed between the two bearings 18, bearing 18 is on support 19, connecting rod 20 is on the crank pin of bent axle 17, and this is simple in structure, but is subjected to big under the equal operating mode of single bearing, make the bent axle size big, the corresponding increase of bearing size, each size is unfavorable for the pump high speed rotating after increasing, the rotating speed that pump can move reduces.Each accessory size is big, the dismounting inconvenience.Part is fragile.
The model utility content
The purpose of this utility model has provided a kind of simple in structure, easy for installation, and stressed effect is good, efficient is high, can improve associated components working life, especially satisfies five connecting levers, four supporting structures that are used for reciprocating pump of high-pressure water pump requirement.
The technical solution of the utility model is as follows:
Be provided with clutch shaft bearing, the 4th bearing in the housing both sides of described support, described crankshaft two end is connected with described clutch shaft bearing, the 4th bearing respectively, in described frame shell, also be provided with second bearing and the 3rd bearing that are used to support described bent axle, be connected with first connecting rod, second connecting rod, third connecting rod, the 4th connecting rod and the 5th connecting rod on the described bent axle, five-bar mechanism is equidistantly arranged on described bent axle, described second bearing is between described first connecting rod and second connecting rod, and the 3rd bearing is between described third connecting rod and the 4th connecting rod.
Adopt said structure in reciprocating pump, to adopt the structural type of 4 bearings, 5 connecting rods, that is: five connecting levers, four supporting structures, these structure 4 bearing reasonable Arrangement can reach good support strength, 5 connecting rod pistons can provide enough pressure again, that just the size of bent axle can be done under the enough situation of support strength is less, being connected bearing shell and can diminishing accordingly of connecting rod and bent axle, thus make the friction pair area reduce to help high speed operation.Be same transmission power, during the reciprocating pump of equal flow pressure, simple in structure, each parts is stressed evenly, coordinates, and can reach high speed operation, and overall dimension is little, light weight, and reliable in structure, maintenance is convenient.Reduce manufacture cost and user cost.
Described frame shell both sides are provided with installation cavity, and described clutch shaft bearing and the 4th bearing are arranged in the described installation cavity, and this installation cavity outside also is provided with end cap.
This structure easy installation and removal, end cap can play the dust-tight effect.
Beneficial effect: the utility model is in same transmission power, and is simple in structure during the reciprocating pump of equal flow pressure, and each parts is stressed evenly, coordinates, and can reach high speed operation, and overall dimension is little, light weight, and reliable in structure, maintenance is convenient.Reduce manufacture cost and user cost.
