the solid lubricant is adaptively arranged in the through hole, and the outer wall of the solid lubricant is attached to the inner wall of the through hole.
Still be equipped with flexible groove on the body, flexible groove is located between an adjacent pair of through-hole, flexible groove includes the cross slot and erects the groove, the cross slot is located this internal, and communicates adjacent through-hole, the one end intercommunication cross slot, the other end of erecting the groove extend to on the outer wall of body.
A chamfer is arranged on one side of the supporting plate facing the inner cavity of the body.
Compared with the prior art, the utility model discloses a solid lubricant protrusion through-hole can form a solid transfer membrane that lubricated good, firmly adhere to and evenly cover between the outer wall of body and the inner wall of outer lane, has reduced the friction loss by a wide margin, moreover under the effect of spring, keeps solid lubricant closely laminating with the inner wall of outer lane all the time, has effectively improved solid lubricant's utilization ratio.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a body; 2. a through hole; 3. an inner cavity; 4. a solid lubricant; 5. a spring; 6. a supporting plate; 7. A transverse groove; 8. a vertical slot.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the low temperature resistant self-lubricating embedded copper bush comprises a body 1, wherein a plurality of through holes 2 are formed in the outer wall of the body 1, one ends of the through holes 2 are located on the outer wall of the body 1, the other ends of the through holes are communicated with an inner cavity 3 of the body 1, a solid lubricant 4, a spring 5 and a supporting plate 6 which are sequentially connected are arranged in the through holes 2, one end of the solid lubricant 4 protrudes out of the through holes 2, the other end of the solid lubricant is located in the through holes 2 and is fixedly connected with the spring 5, one end of the supporting plate 6 protrudes into the inner cavity 3 of the body 1, and the;
solid lubricant 4 is arranged in through-hole 2 with the adaptation, just the outer wall laminating of solid lubricant 4 the inner wall of through-hole 2. The supporting plate 6 is pushed to move towards the through hole 2 in the process that the connecting shaft is inserted into the inner cavity 3 of the body 1, the spring 5 is in a compression energy storage state, the outer ring is sleeved outside the body 1, one end of the solid lubricant 4 props against the outer ring, and the solid lubricant 4 which is protruded and contacted with the outer ring is consumed through friction during rotation, so that a solid transfer film which is good in lubrication, firmly attached and uniformly covered is formed, and friction loss is greatly reduced; the solid lubricant 4 is continuously consumed, the total length is shortened, and the spring 5 is always in a compressed energy storage state, so that a continuous driving force is provided for the solid lubricant 4, one end of the solid lubricant 4 is ensured to be always in contact with the outer ring, and the utilization rate of the solid lubricant 4 is effectively improved; the solid lubricant 4 can be a graphite rod and is tightly attached to the inner wall of the through hole 2, so that a solid transfer film formed by the solid lubricant 4 on the outer ring always exists, and the good lubrication of the body 1 and the outer ring during operation is kept.
Still be equipped with flexible groove on the body 1, flexible groove is located between adjacent a pair of through-hole 2, flexible groove includes cross slot 7 and erects groove 8, cross slot 7 is located in the body 1, and communicates adjacent through-hole 2, the one end intercommunication cross slot 7, the other end of erecting groove 8 extend to on the outer wall of body 1. That is, the transverse groove 7 is arranged inside the body 1 and is not in direct contact with the outside, and the transverse groove 7 is communicated with the plurality of through holes 2, so that when the body 1 contracts in a cooling mode, the transverse groove 7 can reliably reduce the stress in the body 1, and the body 1 is effectively prevented from being broken in the radial direction; the vertical groove 8 is communicated with the transverse groove 7 and the outer part of the body 1, so that when the body 1 is cooled, the temperature difference between the inside and the outside of the body 1 can be reduced, and the body 1 is effectively prevented from being broken in the axial direction; through horizontal groove 7 and perpendicular groove 8, the cooperation in flexible groove promptly, for the expend with heat and contract with cold of body 1, the stress relief, provide the surplus, improve body 1's life.
The side of the supporting plate 6 facing the inner cavity 3 of the body 1 is provided with a chamfer. Set up the chamfer, it is also smooth that the terminal surface of fagging 6 and the linking department between the vertical plane, and a part of chamfer is located through-hole 2, another part is located through-hole 2 outside (the inner chamber 3 of body 1), when the connecting axle inserts into the inner chamber 3 of body 1, the terminal surface of connecting axle touches the chamfer earlier, ensures that the connecting axle can reliably insert inner chamber 3, simultaneously, ensures that fagging 6 can be propped in through-hole 2, avoids connecting axle and fagging 6 to meet the back card die.
