Embodiment Construction

[0007] A bearing hinge. On the basis of the original structure, two pairs of plane thrust bearings are installed at the matching gaps on both sides of the two-tooth leaf and the three-tooth leaf. When the hinge rotates under force in the axial direction, the two-tooth leaf The contact surface between the blade and the three-tooth blade is no longer a sliding friction, but a rolling friction in the bearing, and there is no friction between the blades, so as to achieve the purpose of flexibility and increase the bearing capacity.

Abstract

The invention relates to a bearing hinge. On the basis of an original structure, two pairs of plane thrust bearings are additionally installed at fit clearance points on both sides of a two-tooth hinge leaf and both sides of a three-tooth hinge leaf; when the hinge rotates under axial stress, the friction between the contact surfaces of the two-tooth hinge leaf and the three-tooth hinge leaf is rolling friction in the bearing, instead of sliding friction, and no friction exists between the hinge leaf surfaces, thereby achieving the purposes of agility and bearing capacity enhancement.

Description

technical field [0001] The invention relates to a connecting piece between a door, a window and a frame, in particular to a hinge with a bearing. Background technique [0002] At present, the hinges on the market are mostly assembled by two-tooth leaf, three-tooth leaf, mandrel, and end cover. After assembling the two-tooth leaf and the three-tooth leaf, string the mandrel into the common pipe. , the end cover is embedded on both sides of the pipe through interference fit. This kind of hinge is poorly lubricated when used in doors and windows, and it is difficult to open and close doors and windows. , need to be replaced. Contents of the invention [0003] Aiming at the defects of the existing hinge design, the present invention invents a new type of bearing hinge. The structure of the hinge is simple and can be interchanged with the existing hinge. wear and tear, enhancing the reliability of use. [0004] The technical scheme adopted in the present invention is: on the...
