A metal/plastic slide bearing composite material (2) has a metallic support layer (4), especially of steel, and a porous carrier layer (6), especially a carrier layer (6) applied by sintering from metallic particles (7). A polymer-based slide layer material (8) completely fills the pores of the carrier layer (6) and has fillers that improve the tribological properties. The polymer basis is PTFE. The sliding layer material (8) has 0.1-5% by mass of carbon nanotubes with an external tube diameter of

A thrust bearing is equipped with a resin coating applied to the surface of a base material. Lattice-shaped discharge grooves are formed in the surface of the thrust bearing, and planer protrusions having a square shape or the like are formed at the adjacent positions thereof. Each corner part of each planer protrusion form a sliding surface that slides with respect to a counterpart member. Contaminants such as wear particles that have infiltrated between the counterpart member and the sliding surface fail into the discharge grooves and then are discharged outside of the sliding surface. The chamfering of each corner part to a rounded shape prevents the contaminants from accumulating in the discharge grooves, thus preventing the contaminants from biting into the planer protrusions.

In this sliding bearing, which is provided with a resin coating layer at the surface of a bearing alloy layer layered at a back metal layer, a PAI that degrades with difficulty at high temperatures is used as the main component as the resin binder of the resin coating layer, adjustment particles are included in the resin binder, and as a result, the compressive strength of the resin coating layer is increased, and indentations of the resin coating layer resulting from a shaft are prevented. Meanwhile, a plate solid lubricant is included in the resin binder, and thus sliding characteristics are improved. Also, delamination due to cracks is prevented by the effect of adjusting the orientation of the solid lubricant and the damming effect of the adjustment particles, and thus superior anti-seizure property is provided even in an engine that frequently repeats starting and stopping.

Disclosed is a resin sliding member, including: 0.5 to 25 vol % of calcium fluoride dispersed as particles; and a polyether ether ketone resin as a remainder. The calcium fluoride is crystalline, and a peak intensity of a (111) plane of the calcium fluoride exposed on a sliding surface is larger than a peak intensity of a (220) plane.

Provided is a bearing device for a beauty/health roller which presents no risk of bathwater or bathtub contamination, is hygienic, is less heavy than conventional ball bearings, is devoid of roller rattle, and exhibits a small rotational resistance of the rollers, and to provide the beauty/health roller having this bearing device. A bearing device 4 for a beauty/health roller is used in a beauty/health roller having a grippable body and a roller 3 arranged at the end portion of the body, and rotatably supports the roller 3 on a supporting shaft 2a provided to the end portion of the body. The bearing device comprises a radial bearing 5 into which the supporting shaft 2a is fitted and which rotatably supports the roller 3 on the supporting shaft 2a; a thrust bearing 6 arranged toward one end face of the radial bearing 5; and a preload-applying member 7 interposed between the radial bearing 5 and the thrust bearing 6. The radial bearing 5 and the thrust bearing 6 are slider bearings obtained by being molded from different resin compositions.

A bushing includes a bronze backing layer having a first axial end, a second axial end, and a central opening, the bushing having a cylindrical shape and a porous bronze layer. PTFE or other suitable low friction material is impregnated into the porous bronze layer at one of a radially inner or outer surface of the bushing. A PTFE or other suitable low friction material topical layer is disposed adjacent the impregnated layer. The bushing may optionally comprise a flange which also includes the bronze backing layer, the porous bronze and impregnated layer, and the topical layer on an axially inner or outer surface.

The invention relates to a gear train (1), in particular a planetary gear train, for a wind turbine comprising a plurality of gears, in particular planet gears (4), which are each supported on a shaft (8) by means of a bearing element, wherein the bearing element is a multi-layer plain bearing (7).
摘要:
The present invention provides a plain bearing having improved bearing properties, especially anti-seizure property, initial conformability and cavitation resistance. According to the present invention, a sliding layer is provided on a surface of a bearing alloy layer comprising of a copper-based or aluminum-based alloy, thereby the sliding layer is so structured that, to a polyamide-imide resin of a main constituent, a polyamide resin is added and mixed under a high shear force to form a polymer-alloyed resin binder, in which 1 to 75% by mass of a solid lubricant is dispersed. The sliding layer can have high toughness and strength, as well as improved anti-seizure property, initial conformability and cavitation resistance.
