Description

Bearing extractor
Technical field
This utility model relates to a kind of bearing extractor, it is possible to achieve the dismounting that interference fit larger axis holds.
Background technology
Existing universal dismounting tool for bearings is when converting duty, it is common that rotated around self upper end bearing pin by chela , to adapt to the dismounting of the bearing of different-diameter, the rotation of chela makes itself and bearing be linear contact lay, is applying bigger pulling force Time easily cause stress and excessively concentrate destruction bearing, even cannot complete dismantlement work;In order to avoid this situation, in design During bearing extractor, for different design bearing chelas size, i.e. kit is just for the bearing of a certain diameter, Although dismantlement work can be realized, but the corresponding a set of removal tool special of a kind of bearing size so that bearing removal field stripping work Tool quantity is many, and manufacturing cost is big.
Summary of the invention
The purpose of this utility model is a kind of bearing extractor of design, can be in the unloading process ensureing bearing, protection Bearing is injury-free, reaches to dismantle smoothly, and realizes the purpose of low cost.
The technical solution of the utility model is, described bearing extractor includes jackscrew, adjusting nut, spacing ring, props up Plate, chela, swivel nut, connecting rod, the circumference of described support plate is provided with uniform radial opening, and the upper end of chela is provided with groove And in the opening of clamping bracket, the other end is provided with the claw extended radially outwards;The limit of radial opening it is fixed with on described support plate Position ring, spacing ring is provided with annular groove, adjusting nut is provided with annular protrusion and joins with the annular groove on spacing ring Closing, swivel nut is arranged on adjusting nut by external screw thread and extends to the bottom of support plate, and swivel nut is internally provided with female thread and installs Having jackscrew, the top of described jackscrew to be provided with rotary apparatus, bottom is stretched out from swivel nut, hinged between each chela and swivel nut There are two equivalently-sized connecting rods.Described chela is uniform three, and the top of jackscrew is provided with handle, on described support plate Being provided with anti-turn screw, the described anti-turn screw other end withstands on swivel nut;The jaw position of described chela is to contract.
This utility model in use, by rotating swivel nut, drives chela radial translation by connecting rod, adapts to axle to be removed After the diameter held, block bottom bearing, lock anti-turn screw, rotate jackscrew and drive kit translation, and then realize bearing Dismounting.Each chela of the present utility model is connected with swivel nut by two connecting rods, forms parallelogram, rotates regulation during work Nut can make chela produce radial translation to adapt to bearing demolition size, thereby ensure that chela does not rotates when adjusting, make card Pawl bearing keeps face contact, it is therefore prevented that the stress in unloading process concentrates the destruction produced.Therefore, this utility model is possible not only to Ensure not damage bearing during dismounting, and there is performance-adjustable, adapt to the dismounting of the bearing of different-diameter, be greatly saved into This.
