Oil seal dismounting tool

Abstract

An oil seal dismounting tool comprises an ejector rod bolt, a rotating handle and a cylinder, an opening is formed in the top end of the cylinder, and the ejector rod bolt is vertically screwed into the opening to be in threaded connection with the cylinder; the rotary handle penetrates through the side surface of the cylinder and is vertically connected with the cylinder; a section of meter taper thread is arranged at the bottom of the cylinder and used for being screwed into an inner ring of the oil seal and firmly clamping the oil seal. Compared with the prior art, the oil seal taking-out device is simple in structure, saves labor and is convenient to use, the oil seal can be taken out rapidly and completely, damage to the oil seal is avoided, and resources are saved; and fragments cannot be generated, so that an ideal sealing effect can be achieved after a new oil seal is mounted.

Description

technical field [0001] The invention belongs to the field of dismantling tools for components in construction machinery, and in particular relates to a dismantling tool for oil seals. Background technique [0002] In the field of construction machinery, the oil seal is a mechanical component used to seal oil. It isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. Its working conditions are generally harsh, and the ambient temperature difference is large. There is a lot of dust and frequent vibration of the machine tool, which makes the stress status of the machine part constantly changing, so frequent inspection, maintenance, maintenance and replacement are required, but there is no special oil seal removal tool in the prior art; now factories or maintenance points are generally used to remove oil seals. A flat screwdriver or hook first disassembles the oil seal into pieces, and then takes ...

[0002] In the field of construction machinery, the oil seal is a mechanical component used to seal oil. It isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. Its working conditions are generally harsh, and the ambient temperature difference is large. There is a lot of dust and frequent vibration of the machine tool, which makes the stress status of the machine part constantly changing, so frequent inspection, maintenance, maintenance and replacement are required, but there is no special oil seal removal tool in the prior art; now factories or maintenance points are generally used to remove oil seals. A flat screwdriver or hook first disassembles the oil seal into pieces, and then takes out the pieces one by one. This method not only causes irreversible damage to the oil seal and wastes resources, but also is cumbersome to operate and requires a lot of effort to destroy the oil seal. If the cleaning is not thorough, the residual debris will adhere to the inner wall of the oil seal installation hole, which will make the newly installed oil seal fail to achieve the sealing effect, causing unnecessary trouble and loss
