Embodiment Construction

[0024] The present invention will be described below through a specific embodiment in conjunction with the accompanying drawings.

[0025] refer to figure 1 , figure 2 , first place the entire device directly above the sliding bearing hole to be disassembled, rotate the nut sleeve 2 to move it downward, adjust the pull rod 4 to reduce the distance between the draw hook and the central shaft frame 1, and then extend the draw hook 5 into the inner hole of the slide bearing 12 . By adjusting the nut sleeve 2, driving the pull rod connecting sleeve 3, adjusting the pull rod 4, and the parallel connecting rod 6, the pull hook 5 is driven to adjust the opening degree, so that the pull hook 5 put into the hole fits the inner wall and the lower end surface of the sliding bearing 12. After the support plate 7, thrust self-aligning roller bearing 8, hexagonal flange surface nut 9, hydraulic wrench 10, hydraulic station 11, etc. are installed and fixed, start the hydraulic wrench. Th...

Abstract

The invention discloses a device for detaching and assembling a bearing, which is mainly used for detaching and assembling sliding bearings in hydraulic and pneumatic cylinders and guide sleeves of heavy equipment. The device mainly comprises a central shaft bracket, an adjusting nut, a pull rod connecting sleeve, adjusting pull rods, pull hooks, parallel connecting rods, a support press plate, a thrust aligning roller bearing, a nut, a wrench and the like, wherein three groups of adjusting pull rods, pull hooks and parallel connecting rods are uniformly distributed around the central shaft bracket in the circumferential direction; the central shaft bracket, the adjusting nut, the pull rod connecting sleeve, the adjusting pull rods, the pull hooks and the parallel connecting rods play adapting, axially supporting, connecting and carrying and other roles for sliding bearings with different bore diameters; and the support press plate, the thrust aligning roller bearing, the nut and the wrench are used for fixing the whole device and supplying power for axial extension of the central shaft bracket.

Description

technical field [0001] The invention relates to a device for dismounting and installing bearings in deep holes of heavy equipment, which is mainly suitable for dismounting and installing sliding bearings in hydraulic and pneumatic cylinders and guide sleeves of heavy equipment. Background technique [0002] Because of the interference fit between the sliding bearing and its mounting seat, it is very difficult to install and disassemble the sliding bearing. In the existing maintenance technology, there are two main ways to disassemble the sliding bearing in the upper cylinder of heavy equipment: ① remove the sliding bearing with the mounting seat or the bed, transport it to the machining site, and use boring or drilling ②If the sliding bearing mounting base or the bed is too large and heavy to be transported or machining and clamping is very difficult, the only way to remove the sliding bearing on site is to use flame cutting or other manual tools to destroy the sliding beari...
