Abstract
The utility model particularly relates to an opposed link driving device for a split opposed reciprocating pump, which comprises a crankshaft. The opposed link driving device is characterized in that the crankshaft is provided with a plurality of opposed link driving mechanisms, wherein each opposed link driving mechanism comprises a dual-hole type link and a forked link; the two links are symmetrically distributed at two sides of the crankshaft; the forked link is provided with two large head holes; the connecting part comprises a straight line part and a forked part; the straight line part is connected with a small head hole part; two forks of the forked part are respectively connected with two large head hole parts; the two large head hole parts of the forked link are connected with the crankshaft; the large head hole parts of the dual-hole type link, which correspond to the large head hole parts of the forked link, are arranged on the crankshaft between the two large head hole parts of the forked link; and the connected part of the dual-hole type link is coaxial with the connected part of the forked link. The opposed link driving device overcomes the defect in the prior art that the link cannot meet the technical requirement for the opposed reciprocating pump and has the advantages of low cost and stability and reliability of work.
Description
Technical field
The utility model is specifically related to open the opposed link gearing that the opposed type reciprocating pump is used in a kind of.
Background technique
The bent axle of traditional reciprocating pump has only a side installing connecting rods, in drive the opposed type reciprocating pump the bent axle both sides all need installing connecting rods, and two connecting rods require to be symmetrically distributed in the both sides of camshaft, traditional connecting rod (double hole type connecting rod) comprises a big end hole portion and a microcephaly hole portion, be provided with the linear type joint between big end hole portion and the microcephaly hole portion, adopt traditional connecting rod to be installed in the both sides of camshaft, must adopt the mode that staggers, all the time can't realize being symmetrically distributed the technical requirements of driving the opposed type reciprocating pump in can not satisfying.
The model utility content
The purpose of this utility model is to solve the defective that the prior art connecting rod is opened opposed type reciprocating pump Technology Need in can't adapting to, and a kind of structure order, easy to use, the opposed link gearing of opening opposed type reciprocating pump Technology Need in adapting to are provided.
The utility model is achieved by the following technical solution:
It is a kind of opposed link gearing, comprise bent axle, it is characterized in that being equipped with on the bent axle a plurality of opposed jointed gear units, opposed jointed gear unit comprises a double hole type connecting rod and a forked link, above-mentioned two connecting rods are symmetrically distributed in the both sides of bent axle, the big end hole portion of described forked link is two, the attachment portion is line part and fork-shaped portion, line part is connected with microcephaly hole portion, the outer end of fork-shaped portion is connected with two big end hole portions respectively, two big end hole portions of forked link are connected with bent axle, the big end hole portion of Dui Ying double hole type connecting rod is installed on the bent axle between two big end hole portions of forked link with it, and the joint of described double hole type connecting rod is coaxial with the joint of forked link.
Principle of the present utility model is as follows:
Plain connecting rod and forked link flat opposed are installed on the bent axle, and crankshaft rotating one all two connecting rods are worked simultaneously and changed linear reciprocating motion with rotatablely moving into.
The utility model is installed in forked link and common double hole type connecting rod assembly on the bent axle, realized forked link and double hole type connecting rod in open the opposed both sides that are distributed in bent axle, open the Technology Need of opposed type reciprocating pump during perfection has adapted to.
The utlity model has that cost is low, the stable and reliable operation advantage.Use the utility model, only need production and processing forked link, bent axle and traditional double hole type connecting rod still can continue to use, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model forked link.
As shown in FIG.: 1 double hole type connecting rod; 2 bent axles; 3 forked links; 3-1 big end hole portion; 3-2 fork-shaped portion; The 3-3 line part; 3-4 microcephaly hole portion.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1: bent axle is provided with two groups of opposed jointed gear units, and opposed jointed gear unit comprises a double hole type connecting rod 1 and a forked link 3, and above-mentioned two connecting rods are symmetrically distributed in the both sides of bent axle.
As shown in Figure 2: the 3-1 of big end hole portion of described forked link 3 is two, and the attachment portion is line part 3-3 and the 3-2 of fork-shaped portion, and line part 3-3 is connected with the microcephaly hole 3-4 of portion, and the outer end of the 3-2 of fork-shaped portion is connected with two 3-1 of big end hole portion respectively.
When the utility model is installed, two 3-1 of big end hole portion of forked link 3 are connected with bent axle 2, the big end hole portion of Dui Ying double hole type connecting rod 1 is installed on the bent axle 2 between two 3-1 of big end hole portion of forked link 3 with it, and the joint of described double hole type connecting rod is coaxial with the joint of forked link 3.
