Specific embodiment
Referring to shown in Fig. 1 to 5, according to an embodiment of the invention, providing a kind of roller, it is used in roller type compressor, packet
Roller ontology 1 is included, there is the installation groove 11 with 2 head Matching installation of slide plate in the outer perimeter wall of the roller ontology 1, it is described
The diameter of installation groove 11 is D, and the axial length of the roller ontology 1 is H, 1≤H/D≤8.It is understood that above-mentioned
Matching installation is articulated manner, in the technical solution, since H/D being optimized, to be conducive to using grinding process pair
Installation groove 11 is processed, and the difficulty of processing of installation groove 11 is greatly reduced, from grinding process to installation groove 11 into
Row grinding, can make the installation groove 11 and the matching on the head 21 of slide plate 2 more preferable, this is conducive to it in assembling and roller
It reduces after in formula compressor and has an adverse effect to clearance volume, even more advantageously reduce clearance volume, be conducive to mention
Rise the compression performance of compressor.By multiple authentication in kind, when H/D is more than 8, grinding is carried out to the installation groove 11
It can not achieve, when H/D is less than 1, then using drill bit to lead to the installation groove 11 when processing to the installation groove 11
Or even the deflection of roller ontology 1 is excessive, does not meet 11 morpheme parameter request of installation groove, and since aforementioned ratio is too small, plane
Cut technique also and can not achieve the processing to the installation groove 11.
Preferably, the roller ontology 1 has centre bore 12, and the centre bore 12 is passed through along the axial direction of the roller ontology 1
Lead to the both sides of the face of the roller ontology 1, the installation groove 11 has groove bottom wall, the groove bottom wall and the centre bore 12
Hole wall is L, L >=1mm in the minimum range radially of the roller ontology 1.As L < 1mm, the roller ontology 1 and cunning
2 junction of piece will be easy to be deformed the structural reliability for reducing roller because material thickness is too small, and in processing due to
Thickness too it is small cause to deform it is excessive.
Preferably, the installation groove 11 also has notch, and the notch has the first notched wall, the second notched wall, institute
