Embodiment Construction
[0025] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0026] Such as figure 1 Shown is a schematic structural view of the present invention, the present invention is a bearing removal sleeve, including a support sleeve 1 , an outer ring sleeve 2 , a retainer sleeve 3 , an inner ring sleeve 4 and a threaded pressure rod 5 .
[0027] According to the order of disassembly, the bearings pass through as follows: support sleeve 1, outer ring sleeve 2, retainer sleeve 3 and inner ring sleeve 4; support sleeve 1 and outer ring sleeve 2 are equal in diameter; and the outer ring The diameters of the sleeve 2 , the retainer sleeve 3 and the inner ring sleeve 4 decrease successively.
[0028] The support sleeve 1 is in the sha...

Provided is a bearing removal sleeve. The bearing removal sleeve comprises a supporting sleeve body, an outer ring sleeve body, a retainer sleeve body, an inner ring sleeve body and a threaded compression bar, wherein the supporting sleeve body is in the shape of T, a pull lug clamp is arranged close to one end of the outer ring sleeve body, a groove is formed in the outer circumferential surface, connected with the supporting sleeve body, of the outer ring sleeve body, the pull lug clamp is matched with the groove, the retainer sleeve body is in sliding connection with the outer ring sleeve body, and extends into the outer ring sleeve body to form a removal platform surface, the inner ring sleeve body is in sliding connection with the retainer sleeve body, and extends into the retainer sleeve body to form a removal platform surface, the threaded compression bar is connected with the center of the supporting sleeve body through threads, and the portion, on the supporting sleeve body, of the threaded compression bar is provided with a limiting nut and an adjusting nut. According to the bearing removal sleeve, the outer ring, the retainer and the inner ring of a bearing can be separated without changing tools, the threaded compression bar is used for pushing the bearing to advance, and the bearing removal sleeve is easy, convenient and fast to operate; in addition, the outer ring sleeve body, the retainer sleeve body and the inner ring sleeve body can contract into the supporting sleeve body, and therefore occupied space is reduced.
Description
technical field [0001] The invention belongs to the field of bearing processing equipment, and in particular relates to a tool for disassembling a bearing by using a sleeve. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during power transmission and keep the center of the shaft fixed. [0003] During the installation process of the bearing, it is required to have high precision between the shafts that it cooperates with, and it is generally an interference fit, so as to avoid any vibration during the working process, which will affect the reliability of the operation. In order to meet the requirements of use, during installation, the method of heating the inner ring of the shaft is generally used to enlarge the inner diameter, and then the bearing is assembled to the shaft b...
