Bearing disassembling tool with hammering function

Abstract

The invention discloses a bearing disassembling tool with a hammering function, and relates to tools for disassembling bearings. The bearing disassembling tool is characterized in that the middle of across beam (6) is connected to the two sides of the upper end of an internal ribbed tube (24), upright rods (11) are arranged at the positions close to the two ends of the cross beam respectively, the upper ends of two vertical arms (10) are hinged to the two sides of the lower part of the internal ribbed tube respectively, the inner ends of two pushing rods (15) are hinged to the lower ends of the two vertical arms respectively, the middle parts of the two pushing rods are located in long round holes (16) formed in the lower parts of the two upright rods respectively, springs (12) sleeve theparts, located between the vertical arms and the upright rods, of the two pushing rods respectively, hook pieces (18) are arranged on the opposite sides of the lower ends of the two vertical arms, and the middle part of a screw rod (2) is located in inner threads (7) of the internal ribbed tube. According to the bearing disassembling tool, the two vertical arms are used for clamping a bearing, asmall hammer is used for auxiliarily hammering two hammering heads, and meanwhile, handles is used for controlling the internal ribbed tube and the screw rod to rapidly take down the bearing.

Description

technical field [0001] The invention relates to a tool for dismantling a bearing, in particular to a bearing dismantling tool with a hammering function. Background technique [0002] It is known that a bearing is a key component in mechanical equipment. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its motion and ensure its rotation accuracy. Among them, rolling bearings are the most common. Since the service life of bearings is usually short, the main reason is that the wear and damage during use are usually not caused by fatigue, but are caused by wear, corrosion, seal damage, etc. Damaged bearings need However, for stable installation during use, it is usually necessary to firmly connect the inner ring of the bearing to the shaft "the shaft and the inner ring of the bearing are usually an interference fit", but when replacing the bearing, it is difficult to remove the bearing installed on the shaft Nex...

Among them, rolling bearings are the most common. Since the service life of bearings is usually short, the main reason is that the wear and damage during use are usually not caused by fatigue, but are caused by wear, corrosion, seal damage, etc. Damaged bearings need However, for stable installation during use, it is usually necessary to firmly connect the inner ring of the bearing to the shaft "the shaft and the inner ring of the bearing are usually an interference fit", but when replacing the bearing, it is difficult to remove the bearing installed on the shaft Next, the commonly used method of hammering the outer ring of the bearing to remove the bearing is also difficult to work
