Connection.
Used as preferred scheme of the present utility model, the other end of the gonnecting rod body is embedded in the crosshead pin and is fixed
Connect, and the bolt two is fixedly connected through the gonnecting rod body into the crosshead pin.
Used as preferred scheme of the present utility model, the two ends of the alignment pin two are fastened on the gonnecting rod body and cross respectively
In head pin, the quantity of the alignment pin two is the positive integer more than or equal to 2.
As preferred scheme of the present utility model, determined by alignment pin three between the big end and gonnecting rod body
Position, the quantity of the alignment pin three is the positive integer more than or equal to 2.
Assembling process of the present utility model is as follows：
The crosshead pin and crosshead are assembled first, then by bolt two by the crosshead pin and the company
The body of rod is fixedly connected, to ensure the relative positional accuracy of the gonnecting rod body and the crosshead pin, in the gonnecting rod body and cross
The alignment pin two is provided between head pin, then the connecting rod bearing shell is fastened between the big end and gonnecting rod body, and
The connecting rod bearing shell and big end are positioned by the alignment pin one, it is finally by alignment pin three that the connecting rod is big
Be fixedly connected for the big end and gonnecting rod body by the bolt one again after being positioned by head and gonnecting rod body, is dismantled
When, using opposite assembling process.
Compared with prior art, the beneficial effects of the utility model：
1st, the convenient disassembly of pressure break pump rod is realized；
2nd, due to increasing the contact area of connecting rod small-end bearing and crosshead pin, so as to increase the bearing capacity of connecting rod, prolong
The service life of connecting rod small-end bearing and crosshead pin is grown；
3rd, gonnecting rod body and crosshead pin are processed respectively, and processing economy is more preferable.
