Abstract
The utility model discloses a sloping cam plate provided with a wear-resistant coating and oil holes or oil grooves. The sloping cam plate comprises a disk-shaped sloping cam plate base body; ring-shaped woring planes on two side surfaces of the sloping cam plate base body are coated with self-lubricating wear-resistant coatings; the sloping cam plate is characterized in that concave oil holes or oil grooves are formed in the ring-shaped working planes; the self-lubricating wear-resistant coatings cover the whole ring-shaped working planes and the concave oil holes or oil grooves; and the self-lubricating wear-resistant coatings on the same side surface are connected into a whole. According to the utility model, the wear-resistant coatings which are continuously formed in the oil holes or oil grooves and on the working planes of the sloping cam plate are adopted, so that the phenomena that wear-resistant coatings are not continuous due to excavation of the oil holes or oil grooves and the coatings peel off easily during working can be avoided.
Description
Technical field
The utility model relates to car air conditioning compressor slanting plate, and wherein swash plate is comprised of metallic matrix and sliding contact layer, and particularly layer two surface of contact are with the wear-resistant coating swash plate of oily cave or oil groove.
Background technique
Swash plate is the critical component of compressor of automobile air-conditioning system, and this swash plate is arranged on the interior live axle of compressor axocoel, and common swash plate is comprised of matrix and sliding contact layer.Along with the development of automotive engineering and energy crisis show enhancing with people's environmental consciousness especially, to swash plate lightweight, speed is high, fretting wear is little and environmental protection aspect have higher requirement.Japan electric coating company has taken the lead in releasing the rotating sloping disk type compressor with variable displacement that satisfies above-mentioned requirements, the type compressor is with rotating speed high (maximum transient speed can reach 9200rpm), reliability, controllability is good and accepted by the medium and high classes automobile market rapidly, becomes one of factor of most critical and break through its core low friction pair part-swash plate.Constantly the sliding contact layer is being conducted a research in the industry for many years, emphasis energy is placed on constantly to be sought and tests with a kind of high-performance self-lubricating coating of being mixed with of multiple macromolecular material, spray to by rational preparation process again and make swash plate on matrix, satisfy the demand, the research of this direction has larger progress.Along with going deep into of research and development, how to continue to extend again the working life of wear-resistant coating swash plate on the original basis, become the fresh target of research and development.Analyze from the automobile air conditioner compressor working principle, can the harshest operating mode be resist high friction of moment and the ability that has temperature rise when the swash plate initial start.
The model utility content
Main purpose of the present utility model is to provide that a kind of frictional behaviour is good, the band oil cave of little, the long service life of wearing and tearing or the wear-resistant coating swash plate of oil groove.
In order to reach the above-mentioned requirements the technical solution of the utility model be: it includes the swash plate matrix of dish type, be coated with self-lubricating wear-resistant coating on the annular working plane of swash plate matrix bi-side, it is characterized in that being shaped with recessed oily cave or oil groove on this annular working plane.
Described self-lubricating wear-resistant coating is covered with whole annular working plane and recessed oily cave or oil groove, and the self-lubricating wear-resistant coating of same side is connected.
Make wear-resistant coating swash plate with oily cave or oil groove according to such scheme, it has adopted and be shaped with oily cave or oil groove on working plane, makes working plane when high-speed friction, is stored in the oil lubrication working plane in oily cave or oil groove, form oil film, improve the frictional behaviour of swash plate.If the wear resistant coating that is coated with is successional with the working plane of swash plate in oily cave or oil groove, with regard to avoided because of excavate oily cave, oil groove makes wear resistant coating discontinuous, easily produces the phenomenon of disbonding during work.
Description of drawings
Fig. 1 is shaped with recessed oily cave or the sectional drawing of oil groove swash plate on the annular working plane;
Fig. 2 is that Fig. 1 is at the partial enlarged drawing at A place;
Fig. 3 is the sectional drawing that self-lubricating wear-resistant coating covers whole annular working plane and oily cave or oil groove swash plate;
Fig. 4 is that Fig. 3 is at the partial enlarged drawing at B place.
In figure: 1. swash plate matrix; 2. self-lubricating wear-resistant coating; 3. oily cave or oil groove.
Embodiment
The utility model will be further described below by the drawings and specific embodiments.
Fig. 1, Fig. 2 are the structural representations with the wear-resistant coating swash plate of oily cave or oil groove.As seen from the figure, it includes the swash plate matrix 1 of dish type, is coated with self-lubricating wear-resistant coating 2 on the annular working plane of swash plate matrix 1 bi-side, and is shaped with recessed oily cave or oil groove 3 on this annular working plane.Can also make described self-lubricating wear-resistant coating 2 be covered with whole annular working plane and recessed oily cave or oil groove 3, and the self-lubricating wear-resistant coating 2 of same side is connected, as shown in Figure 3, Figure 4.
Claims (2)
1. with the wear-resistant coating swash plate of oily cave or oil groove, it includes the swash plate matrix of dish type, is coated with self-lubricating wear-resistant coating on the annular working plane of swash plate matrix bi-side, it is characterized in that being shaped with recessed oily cave or oil groove on this annular working plane.
2. the wear-resistant coating swash plate of the oily cave of band according to claim 1 or oil groove, it is characterized in that described self-lubricating wear-resistant coating is covered with whole annular working plane and recessed oily cave or oil groove, and the self-lubricating wear-resistant coating of same side is connected.
