Miniature Bearing Wedge Squeeze Hook Puller

Abstract

The invention discloses a miniature bearing wedge squeezing hook extractor. The miniature bearing wedge squeezing hook extractor comprises two floating plywoods which are capable of wrapping tightly an airplane electric part, a wavy spring sheet is connected to the outer wall of a butt-joint end port of the two floating plywoods, a cap-shaped buckle cover is upwards installed in a clamping opening of the two floating plywoods by using an up-down clamping platform, a hook cover is installed downwards from the top center hole inside the buckle cover, a nut is installed in the position, higher than the buckle cover, of the hook cover, a gasket is installed between the nut and the buckle cover, a wedge with a big bottom and a small end is internally arranged in a via-hole of the hook cover and an inner cross plate of the buckle cover, a bolt which faces the top face of the wedge is installed in the top hole of the hook cover, a small spring is connected between the hook cover and the wedge, and a transparent observation window is arranged on the outer wall of the buckle cover. The miniature bearing wedge squeezing hook extractor has the advantages of being simple in structure, convenient to operate, reliable in clamping, and is capable of effectively improving the extraction efficiency of a miniature bearing and protecting parts at the same time.

Description

technical field [0001] The invention relates to a miniature bearing wedge-squeezing hook puller suitable for taking out miniature bearings in the field of high-precision machinery. Background technique [0002] In some precision gear components on the aircraft, miniature bearings are installed in the blind holes on some parts, and the bearings need to be replaced after a long working time. Due to the extremely small inner diameter of the miniature bearings, the bearing extractors currently on the market cannot work. These parts equipped with miniature bearings, such as precision planetary gear assemblies, are very expensive, so it is required that there should be no slight damage to the parts when extracting the bearings. Use the hook to dig out the inner ring, ball and outer ring of the bearing in sequence, and then repair the remaining outer ring of the bearing in the gear with a carbide drill bit. Such disassembly not only requires extremely high technical requirements fo...

[0002] In some precision gear components on the aircraft, miniature bearings are installed in the blind holes on some parts, and the bearings need to be replaced after a long working time. Due to the extremely small inner diameter of the miniature bearings, the bearing extractors currently on the market cannot work

These parts equipped with miniature bearings, such as precision planetary gear assemblies, are very expensive, so it is required that there should be no slight damage to the parts when extracting the bearings. Use the hook to dig out the bearing inner ring, balls and outer ring in sequence, and then use a carbide drill to repair the residual bearing outer ring in the gear. Such disassembly not only requires extremely high technical requirements for the operator, but may also damage the parts , the risk is great
