And good sealing and reliability can be kept in a long time.
The self-lubricating pad 7 that the utility model uses can be formed as a variety of appropriate configurations, material and size, below will be right
This is described in detail.Wherein, because bent axle 1 generally has the short axle portion 13 extended in lower bearing 6, therefore self-lubricating pad
7 could be formed with centre bore 71, and the counterbore 61 on lower bearing 6 is annular counterbore, and the short axle portion 13 of bent axle 1 prolongs through centre bore 71
Extend the part under the end face of flange of lower bearing 6.As shown in figure 5, accurately it is installed in place for ease of bent axle 1, self-lubricating pad 7
Centre bore 71 can have the taper type shape of flaring from bottom to up.
Self-lubricating pad 7 should can provide good lubrication, to reduce the mill between the thrust boss face 14 of bent axle 1
Damage.Also, the weight that is typically installed as bearing bent axle 1 due to it is simultaneously impregnated with lubricating oil etc. for a long time, thus require certain strong
Spend performance and corrosion resistance.Therefore, self-lubricating pad 7 can be preferably Graphite pad, teflon gasket (also known as Teflon
Imperial pad) or polyether-ether-ketone pad.Exemplified by using self-lubricating pad 7 made of polyether-ether-ketone (PEEK), because it has
Excellent heat-resisting quantity, mechanical property, corrosion resistance and self lubricity, thrust boss face that can long-term effectively with bent axle 1
14 frictions, and good lubrication is provided.
In addition, self-lubricating pad 7 can also be selected as Metal Substrate pad, wherein added with graphite, graphene, curing
At least one of molybdenum, tungsten disulfide, polytetrafluoroethylene (PTFE), and sintered or extrusion process is made.
For ease of installing and avoiding such as binding agent to be dissolved in refrigerant, self-lubricating pad 7 can be with sinking on lower bearing 6
The gap of hole 61 coordinates or interference fit, its size can suitably select according to the size of design structure.Preferably, the two is relative
Size relationship satisfaction -0.01mm≤D-D1≤0.5mm, wherein, D is the diameter of counterbore 61, and D1 is the external diameter of self-lubricating pad 7.
, can be in self-lubricating pad in the utility model one kind more preferred embodiment shown in reference picture 6 and Fig. 7
