Abstract

The invention relates to an assembling tool and assembling method for a single-slit self-lubricating joint bearing, and belong to the field of sliding bearing assembling. The tool and method involve the assembling tool and a support, the upper portion of the assembling tool is conical, the taper angle is 20-30 degrees, the size of the minimum position of the taper angle is smaller than that of theminimum position of the inner diameter of the end surface of the bearing, and the size of the maximum position is 5-8 mm larger than a spherical diameter of the joint bearing; a long-strip-shaped through groove is machined in the radial direction of the taper of the assembling tool, the assembling tool is made of 45 # or 42CrMo, and the hardness of a surface hardening layer of the assembling toolexceeds the hardness of a bearing outer ring and reaches HRC 60 or above; and the assembling tool needs to be used in cooperation with the cuboid support, and the cuboid support is placed right abovethe outer ring in the assembling process. According to the assembling tool, die machining is is simple, in the assembling process, the operation is flexible and convenient, hours of work are saved, no damage exists during joint bearing assembling, the product quality is greatly improved, and the using reliability of the bearing is guaranteed.

Description

technical field [0001] The invention relates to the field of sliding bearing assembly, in particular to an assembly tool and an assembly method for a single-slit self-lubricating joint bearing. Background technique [0002] With the continuous improvement of my country's industrial technology level, the manufacturing level of self-lubricating sliding bearings is becoming more and more mature, especially self-lubricating joint bearings, which have been widely used in various fields. Among them, the demand for single-slot self-lubricating bearings is gradually increasing due to its simple structure and high matching precision, and its structural form is relatively special, that is, a slot is processed without damage in the radial direction of the outer ring of the bearing. The gap method is used to put the inner ball, and then form a whole self-lubricating joint bearing. In view of this, the bearing assembly method and tools are particularly important. [0003] For example, t...
