Embodiment Construction

[0027] Such as figure 2 as well as image 3 , the present invention provides an 8-shaped bearing removal device, which includes two sets of threaded rod assemblies, an operating handle 12, a support frame 14 and a support base 15; each set of threaded rod assemblies includes a threaded rod 11, a force transmission nut, a compression Nut, guide sleeve 16, pressing plate 17, expansion ring 18 and briquetting block 19; There is a through groove on the support frame 14, and the support seat 15 runs through the through groove, so that the support frame 14 and the support seat 15 form the cross-overlapping of the upper and lower positions; There is a threaded through hole on the support frame 14, and the front part of the operating handle 12 is an externally threaded rod. The frame 14 and the support seat 15 move oppositely or backward in the axial direction; each threaded rod is sequentially equipped with a force transmission nut, a compression nut, a guide sleeve 16, a pressure ...

Abstract

The invention belongs to the field of mechanical product assembling and disassembling, and relates to an 8-shaped bearing disassembling device and disassembling method. The device comprises an operating handle, a supporting frame and two groups of threaded rod assemblies; a movable through groove is formed in the supporting frame in the axial direction of the supporting frame; the two groups of threaded rod assemblies are movably arranged in the movable through groove of the supporting frame in parallel; the two groups of threaded rod assemblies can move relatively; and the operating handle isarranged between the two groups of threaded rod assemblies and penetrates through the supporting frame. The invention provides an 8-shaped bearing disassembling device and disassembling method, the device and the method are convenient to nondestructively disassemble an 8-shaped bearing, convenient to use and high in reliability.

Description

technical field [0001] The invention belongs to the field of loading and unloading of mechanical products, and relates to a tool and method for pulling out sleeves of bearing parts, in particular to a dismounting device and method for an 8-shaped bearing. Background technique [0002] In the product design of the gear pump (or the integrated structure of the gear pump regulator) used in the new research aircraft engine control system, there is a new structure in the design of the assembly structure of a pair of bearings and the housing ( figure 1 ), consisting of: bearing assembly (including closed radial rubber ring groove), O-shaped rubber sealing ring, cylindrical pin (a pair of bearings connected as a whole by pins) and shell (deep inner hole, no disassembly process structural design and There are multiple fastening screw piles interfering with the cloth on the installation end surface), which makes it difficult to disassemble and disassemble. For the above-mentioned ho...
