Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance, specifically to an auxiliary device for installing shaft end skeleton oil seals. Background Technology

[0002] The skeleton oil seal is a typical example of an oil seal. The function of an oil seal is to isolate the lubricating medium of rotating equipment from the rotating rod components, preventing lubricating oil leakage that could lead to low oil levels, resulting in poor bearing lubrication and damage to the rotating equipment.

[0003] In existing technologies, the installation of skeleton oil seals mainly relies on hand hammering, rubber mallet pressing, or pressure mechanisms. For example, hand hammering requires repeated tapping, which is not only time-consuming and laborious, but also prone to uneven force, leading to deformation of the oil seal lip, spring detachment, or seal failure. While rubber mallet installation can reduce impact force, it still presents problems such as high operational difficulty and insufficient installation accuracy. Currently, there are no effective auxiliary tools on the market for installing skeleton oil seals, which cannot meet the daily maintenance and troubleshooting work of the conventional islands and auxiliary equipment of units 1-4. Since the skeleton oil seals are installed in the end holes and are made of rubber, they cannot be positioned for installation. There is an urgent need for a special tool to improve equipment maintenance efficiency and reduce the damage rate of skeleton oil seals.

[0004] In summary, there is an urgent need to develop a versatile and easy-to-operate auxiliary device for installing skeleton oil seals, applicable to a certain range of skeleton oil seal sizes. Utility Model Content

[0005] This application provides an auxiliary device for installing a shaft end skeleton oil seal, which solves the above-mentioned problems. By adjusting the radial direction of the main support claw, the auxiliary device for installing skeleton oil seals can be applied to the auxiliary installation of skeleton oil seals of different sizes.

[0006] The specific technical solution of this application is as follows:

[0007] An auxiliary device for installing a shaft end skeleton oil seal includes:

[0008] Adjustment plate,

[0009] At least two main support claws are used to support the skeleton oil seal. The main support claws are movably installed along the radial direction of the adjustment plate and are movably installed on the adjustment plate.

[0010] In some implementations, the adjustment disc is equipped with a handle for ease of operation.

[0011] In some implementations, to facilitate the installation of preset-sized skeleton oil seals, the handle is provided with an adjustment pad for installing preset-sized skeleton oil seals. The preset size refers to a commonly used fixed size with a cut diameter of less than 50mm.

[0012] In some implementations, a universal level is fixedly installed on the upper end face of the adjustment disc to facilitate confirmation of whether the oil seal is level during installation.

[0013] In some implementations, to facilitate the installation of oil seal skeletons of different sizes, the bottom end face of the adjustment disc is provided with a sliding groove for installing the main support claw, and the main support claw moves radially along the sliding groove.

[0014] In some implementation schemes, to facilitate the installation of oil seal skeletons of different sizes, when installing a larger size oil seal skeleton, first loosen the first bolt, then adjust the main support claw radially outward to the appropriate size of the oil seal skeleton, then tighten the first bolt, and so on, adjusting the remaining bolts. Conversely, when installing a smaller size oil seal skeleton, first loosen the first bolt, adjust the main support claw radially inward to the appropriate size of the oil seal skeleton, then tighten the first bolt, and so on, adjusting the remaining bolts. This process is repeated to complete the installation of oil seal skeletons of different sizes.

[0015] In some implementations, the clamping claw is movably positioned on the outside of the main support claw. The thicker the skeleton oil seal, the further the clamping claw moves downward until it reaches the appropriate size, and then it is fixed by a third bolt. This is to prevent the skeleton oil seal from shaking during the hammering process and to avoid additional manual support, thereby completing the installation of the skeleton oil seal in a deeper location.

[0016] In some implementations, to prevent the oil seal skeleton from falling off when installing it without using the main support claw and clamping claw, a strong magnetic strip is fixedly installed on the bottom end face of the adjustment plate. When installing the oil seal skeleton skeleton using only the handle and adjustment plate, it can be attracted and fixed. This method uses a flat surface facing outward for direct embedding installation.

[0017] In some implementation schemes, at least two measuring point clips are fixedly installed on the outer wall of the adjustment disc. A ruler is installed inside the measuring point clip. By adjusting several sets of rulers to the same scale, it is determined that the oil seal skeleton is in a horizontal state when it is installed, thereby achieving the purpose of data-driven detection of installation.

[0018] Compared with existing technologies, the advantages and positive effects of this utility model are:

[0019] When installing a larger size oil seal skeleton, the main support claw should be adjusted radially outwards; when installing a smaller size oil seal skeleton, the main support claw should be adjusted radially inwards; when the oil seal skeleton needs to be installed deep within the seal, first loosen the bolts between the main support claw and the clamping claw, then adjust the clamping claw downwards to the appropriate size, and finally tighten the bolts to secure it. This prevents the oil seal skeleton from moving during hammering and avoids the need for additional manual support. By adjusting the main support claw and clamping claw as described above, the oil seal skeleton installation auxiliary device can be adapted to assist in the installation of oil seal skeletons of different sizes.
