Abstract
A kind of anti-roller type crank pins of oil pumper, including crown nut, pin key and bearing block are the utility model is related to, is pin key between crown nut and bearing block, described pin key is square.Pin key on crank pins is improved to square by the utility model from ellipse, and abrasion is so greatly reduced during moving back and forth, the problem of effectively preventing crank pins bearing from easily deviating from, and reduces the generation of accident.
Description
Technical field
The utility model belongs to oilfield machinery field, is related to a kind of anti-roller type crank pins of oil pumper.
Background technology
Crank pins is needed to use on the connecting rod of oil pumper, facilitates connecting rod to move up and down.But the pin key one of crank pins
As be ellipse, worn in moving back and forth very serious, cause crank pins bearing easily to be deviate from, cause mechanical accident.Cause
This to existing crank pins, it is necessary to be improved to overcome above mentioned problem.
The content of the invention
The purpose of this utility model is to provide a kind of anti-roller type crank pins of oil pumper, solves current crank pins bearing
The problem of easily abjection causes mechanical accident.
The utility model is achieved through the following technical solutions：A kind of anti-roller type crank pins of oil pumper, including crown
Nut, pin key and bearing block, are pin key between crown nut and bearing block, and described pin key is square.
Further, the internal buckle of described crown nut, which is designed with, prevents pounding groove.
Using the good effect of above-mentioned technical proposal：Pin key on crank pins is improved to by the utility model from ellipse
Square, so greatly reduces abrasion during moving back and forth, and effectively prevents what crank pins bearing from easily deviating from
Problem, reduce the generation of accident；In addition, baffle plate screw internal buckle when the anti-design for pounding groove can prevent from adjusting ginseng, replacing pin
Smash.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the internal buckle schematic diagram of crown nut.
In figure, 1 crown nut, 2 pin keies, 3 bearing blocks, 4 prevent pounding groove.
Embodiment
The technical solution of the utility model is described further below in conjunction with the accompanying drawings, but should not be construed as to this practicality
New limitation：
Fig. 1 is structural representation of the present utility model, as illustrated, a kind of anti-roller type crank pins of oil pumper, including
Crown nut 1, pin key 2 and bearing block 3, are pin key 2 between crown nut 1 and bearing block 3, and described pin key 2 is square.Will
Pin key on crank pins is improved to square from ellipse, and abrasion is so greatly reduced during moving back and forth, is had
The problem of preventing crank pins bearing from easily deviating from of effect.
Fig. 2 is the internal buckle schematic diagram of crown nut, as illustrated, the internal buckle of described crown nut 1 be designed with it is anti-pound it is recessed
Groove 4.Prevent pounding in groove because internal buckle is located at, therefore internal buckle can be protected.
Pin key on crank pins is improved to square by the utility model from ellipse, so in the process moved back and forth
In greatly reduce abrasion, the problem of effectively preventing crank pins bearing from easily deviating from, reduce the generation of accident；It is in addition, anti-
Pounding the design of groove can prevent from smashing baffle plate screw internal buckle when adjusting ginseng, replacing pin.
