Abstract
The utility model provides a passenger train spiral oil groove leaf spring round pin, includes leaf spring round pin body, its characterized in that, the side of leaf spring round pin body is opened has along axial evenly distributed's spiral oil groove, and it has the oil-out to open on the spiral oil groove of the department of centre portion on the leaf spring round pin body, and the oil-out communicates with each other with the oiling mouth of this end of leaf spring round pin body. The utility model discloses a passenger train spiral oil groove leaf spring round pin is through adopting spiral oil groove for lubricating grease can be sufficient leaf spring book earmuff and leaf spring pin contact surface, and is lubricated abundant even, effectively avoids dry grinding and abnormal sound to produce, and the contact atress everywhere of leaf spring round pin is even simultaneously.
Description
Technical Field
The utility model relates to a passenger train spiral oil groove leaf spring round pin.
Background
The passenger train leaf spring is through the leaf spring eye cover of its tip on the leaf spring round pin, and rethread spacing bolt nut is fixed in the leaf spring seat. The structure has the defects that the leaf spring ear rolling sleeve and the leaf spring pin are not lubricated uniformly and fully, local dry abrasion and abnormal sound are easily caused, in addition, the annular oil groove of the transverse ring in the middle part enables the stress of the leaf spring pin to be non-uniform, and the middle part is easy to break.
Disclosure of Invention
The utility model aims at providing a atress is even, lubricated abundant, effectively avoids dry milling and abnormal sound's passenger train spiral oil groove leaf spring round pin.
The utility model discloses a passenger train spiral oil groove leaf spring round pin, including leaf spring round pin body, its characterized in that, open the side of leaf spring round pin body has along axial evenly distributed's spiral oil groove, and it has the oil-out to open on the spiral oil groove of positive department on the leaf spring round pin body, and the oil-out communicates with each other with the oiling mouth of this end of body of leaf spring round pin.
The utility model discloses a passenger train spiral oil groove leaf spring round pin is through adopting spiral oil groove for lubricating grease can be sufficient leaf spring book earmuff and leaf spring pin contact surface, and is lubricated abundant even, effectively avoids dry grinding and abnormal sound to produce, and the contact atress everywhere of leaf spring round pin is even simultaneously.
