And a jack seat is arranged in the center of the base for placing a jack. The hoop comprises an annular hoop with a hoop handle, the upper part and the lower part of the annular hoop are oppositely combined into a whole, and the hoop handle is combined and fixed through a clamping hole of the clamping head.
Preferably, the threaded pull rod is a pull rod bolt with high strength of more than 8.8 grades, and the nut is made of the same material.
Preferably, the bolt pitch is 1.5-2 mm.
Preferably, the clamping head is formed by processing a steel plate with the thickness of more than 20 mm.
Preferably, the chuck is welded firmly with the threaded pull rod with the length of more than 100 mm.
Preferably, the clamp is formed by machining a steel plate with the thickness of more than 20mm, and the surface of the semicircular clamp ring needs to be polished smoothly.
The technical scheme of the utility model has the following beneficial technical effects:
the whole quality of extracting tool is lighter, easily control and fixed, can keep direction and angle stable in the dismantlement process, prevents that the skew from leading to equipment to damage.
The jack is used for pulling, so that the working efficiency can be effectively improved.
The clamp can completely cover the cross section of the rolling bearing and the pair wheel, so that the stress of the contact part is uniform, the separation of the inner ring and the outer ring of the bearing due to uneven stress is prevented, and the damage to the bearing and the pair wheel and the occurrence of safety accidents are avoided.
The clamp with different sizes can enable one set of disassembling tool to be flexibly applied to bearings and paired wheels with different sizes, and manpower and material resources are saved.
