Abstract
A reciprocating mechanism for opposed reciprocating pumps, which is disclosed by the utility model, relates to the technical field of reciprocating pumps and comprises a crankshaft, a bearing bush, cranks, crank-connecting rods and crossheads, the crankshaft is connected with the symmetric cranks through the embedded bearing bush, the cranks are articulated with the two symmetric crank-connecting rods, and the other ends of the crank-connecting rods are articulated with the crossheads. The reciprocating mechanism for opposed reciprocating pumps ensures that the parts on both ends of the crankshaft of the power end of an opposed reciprocating pump are the same and are uniformly stressed, meanwhile, through oil holes in both ends also can conveniently carry out forced lubrication, consequently, the bearing capability of the transmission part is enhanced, the demand of high-power high-pressure high-flow reciprocating pumps is satisfied, the bearing capability of the parts is enhanced, and the service lives of the parts are prolonged.
Description
Technical field
The utility model relates to reciprocating pump technical field, relates in particular to a kind of reciprocator of opposed type reciprocating pump.
Background technique
For adapting to the needs of large flow reciprocating pump, opposed type reciprocating pump arises at the historic moment, but how to make opposed type reciprocating pump crankshaft two ends part identical stressed and have enough bearing capacitys, is restricting the development of opposed type reciprocating pump always.Chinese patent 201020682658.2 Opposed link driving devices, disclose and adopted one end that conventional CONCENTRIC REDUCER connecting rod is installed, one end adopts the forked type connecting rod of patented technology 201020682660.x, because the major part of forked type connecting rod is diplopore, and the conventional connnecting rod big end of the other end is single hole, be difficult to guarantee that two kinds of big end bearing shells are stressed just the same, cause crankshaft wear degree different.Moreover the forked type position force structure of forked type connecting rod is bad, be difficult to meet the force request of high-power high voltage reciprocating pump.The oilhole that simultaneously forked type bar linkage structure is difficult to perforation is used for pressure lubrication connecting rod bearing shell, crosshead bearing shell etc., also greatly reduces its bearing capacity.
Model utility content
The utility model is intended to for the deficiency existing in background technique, and a kind of reciprocator of opposed type reciprocating pump is provided.
The reciprocator of opposed type reciprocating pump of the present utility model, by bent axle, bearing shell, crank, crank connecting rod and crosshead form, bent axle is connected with symmetrical crank by Embedded bearing shell, crank upper hinge has connected two symmetrical crank connecting rods, crosshead that the other end of crank connecting rod is hinged.
As further improvement of the utility model, the inside of described bearing shell, crank, crank connecting rod and crosshead is equipped with oilhole.
As further improvement of the utility model, the oilhole of described bearing shell, crank, crank connecting rod and crosshead inside all communicates.
The reciprocator of opposed type reciprocating pump of the present utility model makes opposed type Reciprocatin pump power end crankshaft two end part identical, stressed identical, two ends divide other perforation oilhole also to realize very easily pressure lubrication simultaneously, improve the bearing capacity of driving component, meet the needs of the large flow reciprocating pump of high-power high voltage, improved bearing capacity and the working life of part.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reciprocator of opposed type reciprocating pump of the present utility model.
Embodiment
Reciprocator below in conjunction with Fig. 1 to a kind of opposed type reciprocating pump of the present utility model, is described further.
The reciprocator of opposed type reciprocating pump of the present utility model, by bent axle 1, bearing shell 2, crank 3, crank connecting rod 4 and crosshead 5 form, bent axle 1 is connected with symmetrical crank 3 by Embedded bearing shell 2, on each crank 3 all chain connection crank connecting rod 4, and 4 one-tenth symmetry arrangement of crank connecting rod, the other end of crank connecting rod 4 hinged crosshead 5.
The inside of described bearing shell 2, crank 3, crank connecting rod 4 and crosshead 5 is equipped with oilhole 6, and the oilhole 6 of bearing shell 2, crank 3, crank connecting rod 4 and crosshead 5 inside all communicates.
Working procedure of the present utility model is as follows:
Bent axle rotates under the driving of prime mover, driving in crank has bearing shell to swing in crankshaft eccentric circle circumferencial direction certain limit, order about the left and right crank connecting rod that is hinged on crank and move right left or simultaneously respectively simultaneously, also drive simultaneously with left and right crank connecting rod respectively hinged left and right crosshead move reciprocatingly to the left or to the right.
Its working principle is as the quadratic crank mechanism in Der Grundsatz der Maschinen.By the oilhole through crank, bearing shell, crank connecting rod, crosshead, lubricant oil can be forced to inject each friction pair.
The part of the utility model crankshaft two end is identical, two ends part stressed identical, and the dynamic balancing while being easy to accomplish two ends component motion, has solved the unbalance vibration problem of opposed pump.Two ends divide other perforation oilhole also to realize very easily pressure lubrication, have improved bearing capacity and the working life of part.
In concrete enforcement of the present utility model, left and right crank connecting rod is hinged with crank, left and right crosshead respectively, can be globular hinge, can be also that pin is hinged, can be also spherical hinged with mixing of pin, can need to determine according to practical structures.
In concrete enforcement of the present utility model, bearing shell can be also rolling bearing.
