Differential type bearing dismounting device

Abstract

The invention relates to a bearing dismounting device, in particular to a differential type bearing dismounting device. The differential type bearing dismounting device comprises a power shaft, a pre-tightening sleeve, an upper differential sleeve, a movable joint, a lower differential sleeve, a connecting plate, an arc-shaped clamping plate and pins, wherein the power shaft is in threaded connection with the pre-tightening sleeve, the upper differential sleeve and the lower differential sleeve respectively in threaded connection with the pre-tightening sleeve, the upper end of the connecting plate is connected with the upper differential sleeve through the pin, the middle is connected with the movable joint through the pin, and the lower end of the connecting plate is connected with the arc-shaped clamping plate through the pin. The differential type bearing dismounting device has the advantages that the device is simple in structure and convenient to use, the upper differential sleeve and the lower differential sleeve form differential, the stroke length of the device on the pre-tightening sleeve is decreased, and the size of a bearing dismounting tool is decreased; a thread is machined on the inner arc surface of the arc-shaped clamping plate, the friction force between the inner arc surface and the cylindrical surface of a bearing is increased, and the device facilitates dismounting; the defects of large size, complicated structure and inconvenient carrying of a common bearing dismounting tool are overcome, and the device has a certain practical value.

Description

[0001] This application is a divisional application of the Chinese invention patent application 201510237300.6 filed on May 12, 2015 with the title of "a differential bearing removal device". technical field [0002] The invention relates to a bearing dismounting device, in particular to a differential bearing dismounting device. Background technique [0003] With the rapid development of the bearing industry, bearings are now widely used in various industries. In general machinery, deep groove ball bearings are the most common application. Deep groove ball bearings are installed on the journal near the shaft end when they are in use. The interference fit of the journal increases the difficulty of dismounting the bearing due to its large interference. At present, there are few special dismounting tools for bearings on the market. The working principle is mostly to clamp the lower end surface of the bearing with claws, and then turn the central threaded shaft to make the shaf...

AI Technical Summary

Problems solved by technology

At present, there are few special dismounting tools for bearings on the market. The working principle is mostly to clamp the lower end surface of the bearing with claws, and then turn the central threaded shaft to make the shaft on which the bearing is installed move down, so that the bearing is disassembled. During the disassembly process The larger travel of the central threaded shaft makes the bearing removal tool larger and bulkier for portability
