Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is for existing dismounting inconvenience, connects not firmly, and the easy loosening and problem such as come off after long-term vibration, provides a kind of taper pin.
As shown in Figure 1, embodiment of the present utility model provides a kind of taper pin, and its left and right two ends are respectively left cone, right cone, and one-body molded by left cone, cylindrical body and right cone.
The left and right end of described taper pin 1 offers respectively left hand thread fastener hole 11, right-hand thread fastener hole 12.
Between described left hand thread fastener hole 11 and right-hand thread fastener hole 12, be connected with axial lubrication road 13, the middle part of described taper pin is provided with the radially oilhole 14 intersecting vertically with described axial lubrication road 13.
In the present embodiment, described radially oilhole 14 is through hole.Also can, according to actual conditions, described radially oilhole be processed as to blind hole, as shown in Figure 3.
As shown in Figure 2, described taper pin 1 is arranged in an ear 2, and this ear 2 is provided with left support hole and right support hole.
Between described left cone and left support hole, be provided with left tapered sleeve 3, these left tapered sleeve 3 internal surfaces and left outer surface of cone are cone match, and described left tapered sleeve 3 is fixedly connected with described taper pin 1 with the left clamping bolt 4 being spirally connected with described left hand thread fastener hole 11 by pressing plate 8.
