Oil-seal fool-proofing mounting tool

Abstract

The invention discloses an oil-seal fool-proofing mounting tool which comprises an annular plane for loading an oil seal bottom surface, a cylindrical protrusion arranged at the middle of the annular plane and a raised pin arranged on the annular plane, wherein the height of the pin is less than the depth of an oil seal groove, and the pin is positioned inside the oil seal groove in case of oil seal normal mounting state. The oil-seal fool-proofing mounting tool provided by the invention has a simple structure, is convenient to use, can effectively prevent the reverse mounting of the oil seal from to enable the oil seal to act correctly.

Description

technical field [0001] The invention relates to a structure for installing an oil seal, in particular to a fool-proof installation tool for the oil seal. Background technique [0002] A seal whose function is to isolate the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. When installing the oil seal, it is especially necessary to pay attention to the correct installation direction, otherwise it will be difficult to play the role of sealing . The structure of the oil seal is as figure 1 As shown, it is a ring, with grooves on the bottom surface and a flat top surface; the installation of the oil seal is generally realized by the tooling for installing the oil seal. The existing tooling structure for installing the oil seal is as follows figure 2 As shown, it includes the annular plane supporting the bottom surface of the oil seal. The middle of the annular plane is a cylindrical protrusion, which ...

The structure of the oil seal is as figure 1 As shown, it is a ring, with grooves on the bottom surface and a flat top surface; the installation of the oil seal is generally realized by the tooling for installing the oil seal. The existing tooling structure for installing the oil seal is as follows figure 2 As shown, it includes the annular plane supporting the bottom surface of the oil seal. The middle of the annular plane is a cylindrical protrusion, which is used to penetrate into the through hole in the middle of the oil seal and play a role in limiting the oil seal. When installing, first install the oil seal on the Install the tooling of the oil seal (put the oil seal on the cylindrical protrusion, and the bottom surface of the oil seal is in contact with the annular plane), and then use the hydraulic press to press the bottom of the tooling to press the oil seal into the product; although the entire installation process is extremely simple, it will When the oil seal is set on the cylindrical protrusion, there is no device to detect the orientation of the bottom of the oil seal. If the orientation of the oil seal is reversed, it can still be installed normally, but the oil seal loses its original role.
