Abstract
The utility model discloses a copper-based alloy embedded plastic solid lubricating bearing and aims at providing a copper-based alloy embedded plastic solid lubricating bearing which has simple structure, good processability and excellent lubrication performance and can be used in liquid. The lubricating bearing comprises a tubular shaft sleeve which is made of copper alloy; holes which are uniformly distributed and communicated with the inner wall and the outer wall of the shaft sleeve are arranged on the periphery of the shaft sleeve; and solid lubricating agents are embedded in the holes. The utility model is characterized in that the solid lubricating agent is PTFE or is mainly PTFE. The solid lubricating agent used by the utility model is not made of traditional powdery graphite and molybdenium disulfide but the PTFE; PTFE, namely polyfluortetraethylene, is an engineering plastic with good antifriction property and good corrosion property and is used as the solid lubricating agent; when in use, the PTFE can be firmly bonded on the surface of a sliding body; and even being used in liquid, the PTFE can also be taken. The solid lubricating bearing can be widely used in various water environments.
Description
Technical field
The utility model relates to a kind of sliding bearing, relates in particular to a kind of copper base alloy and inlays the plastic solidification lubricating bearings.
Background technique
A kind of title solid embedded bearing is arranged in market, it is the axle sleeve made from Cuprum alloy, is shaped on the hole that the axle sleeve inside and outside wall connects on the circumferential surface of axle sleeve, is inlaid with solid lubricant in the hole, the solid lubricant that is adopted is generally the solid of graphite and/or molybdenum disulfide, and soaks in lubricant oil.In use, make solid lubricant be coated in friction surface, form the anti-attrition layer of oil, solid lubricant, make the not directly contact of mill material by frictional heat.If but be used in for such sliding shaft sleeve under the operating mode of liquid, as will be in water with oil, solid lubricant take away, and do not reach the effect of anti-attrition.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, good manufacturability, greasy property good, and the copper base alloy that can use in liquid is inlayed the plastic solidification lubricating bearings.
In order to reach above-mentioned requirements, the technological scheme that is adopted: comprise tubular axle sleeve, described axle sleeve is made with Cuprum alloy, on the circumferential surface of axle sleeve, be shaped on hole equally distributed and that connect with the axle sleeve inside and outside wall, be inlaid with solid lubricant in the hole, it is characterized in that described solid lubricant is PTFE or mainly is PTFE.
Inlay the plastic solidification lubricating bearings according to the copper base alloy that such scheme is made, used solid lubricant is not that graphite, the molybdenum disulfide with conventional powdered is made, but use PTFE, PTFE is a teflon, it is a kind of engineering plastics with fine anti-attrition and decay resistance, with it as solid lubricant, in use, it can be firm be bonded in the slide mass surface, can even in liquid, use by the liquid band yet.Can in various water environments, be extensive use of.
Description of drawings
Fig. 1 is the structural drawing that copper base alloy is inlayed the plastic solidification lubricating bearings;
Fig. 2 is the structural drawing that copper base alloy that the end at axle sleeve is shaped on flange edge is inlayed the plastic solidification lubricating bearings.
Wherein: 1, axle sleeve; 2, hole; 3, solid lubricant; 4, internal surface; 5, flange edge.
Embodiment
Below in conjunction with accompanying drawing the utility model content is further described.
Fig. 1 is the structural drawing that copper base alloy is inlayed the plastic solidification lubricating bearings.It comprises tubular axle sleeve 1, and described axle sleeve 1 usefulness Cuprum alloy is made, on the circumferential surface of axle sleeve 1, be shaped on equally distributed and with the hole 2 that axle sleeve 1 inside and outside wall connects, be inlaid with PTFE in the hole 2 or mainly be PTFE, as solid lubricant 3.
Described Cuprum alloy is bronze or brass.Its medium bronze can be tin bronze or aluminum bronze or phosphor bronze or lead bronze.Brass is aluminium brass.The gross area in above-mentioned hole 2 account for axle sleeve 1 internal surface 4 gross areas 20% to 35% between.In PTFE, can add some additives according to the requirement of using.
Can also be shaped on flange edge 5 at an end of axle sleeve 1 according to usage requirement, the axially locating that is used for axle sleeve 1 as shown in Figure 2.
