Abstract
A pin shaft comprises a pin shaft body, wherein one end surface of the pin shaft body is provided with an axial oil conveying channel, a radial oil conveying channel is arranged on the external circular surface of the pin shaft body, the axial oil conveying channel is communicated with the radial oil conveying channel, a drainage groove is arranged in the external circular surface of the pin shaft body, and the drainage groove is communicated with the radial oil conveying channel. The pin shaft has the advantage that the external circular surface of the pin shaft body is better lubricated.
Description
Technical field:
The utility model relates to a kind of link, specifically is a kind of bearing pin.
Background technique:
Connect two or more when having in relative rotation component, usually need to use bearing pin to connect, since at component in the process that bearing pin rotates, can produce larger frictional force, therefore need to use oil lubrication, for convenient periphery at bearing pin adds lubricant oil, usually an end face at bearing pin is provided with axial oil transportation channel, and be provided with radially oil transportation channel at the periphery of bearing pin, axially oil transportation channel communicates with oil transportation channel radially, lubricant oil by axial oil transportation channel and radially oil transportation channel enter on the bearing pin periphery, and then be diffused into the periphery of whole bearing pin, because the working environment of bearing pin is relatively poor, the dust that the external world enters easily hinders the diffusion of lubricant oil, therefore, can not lubricate preferably away from the periphery in oil transportation channel outlet port radially on the bearing pin, make the too early wearing and tearing of component and bearing pin.
The model utility content:
The technical problems to be solved in the utility model is that a kind of bearing pin that its periphery is better lubricated is provided.
Technical solution of the present utility model is, provide a kind of bearing pin with following structure: comprise the bearing pin body, an end face of bearing pin body is provided with axial oil transportation channel, and the periphery of bearing pin body is provided with radially oil transportation channel, axially oil transportation channel communicates with oil transportation channel radially, wherein, the periphery of bearing pin body is provided with drainage trough, and drainage trough communicates with oil transportation channel radially.
After adopting above structure, compared with prior art, the utility model bearing pin has the following advantages: because the periphery of bearing pin body is provided with drainage trough, drainage trough communicates with oil transportation channel radially, therefore, lubricant oil is by axial oil transportation channel with after radially oil transportation channel flows out, and can flow to preferably on the periphery of the bearing pin body away from radially oil transportation channel exports by drainage trough, thereby the periphery of bearing pin body can be lubricated preferably again.
Description of drawings:
Fig. 1 is the perspective view of the utility model bearing pin;
Fig. 2 is that the master of the utility model bearing pin looks the sectional structure schematic diagram.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model bearing pin is described further:
As depicted in figs. 1 and 2, in this embodiment, the utility model bearing pin comprises the bearing pin body, the right side of bearing pin body is provided with axial oil transportation channel, and the periphery of bearing pin body is provided with radially oil transportation channel, axially oil transportation channel communicates with oil transportation channel radially, and the periphery of bearing pin body is provided with drainage trough, and drainage trough communicates with oil transportation channel radially.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
