Abstract
The utility model relates to a bearing extractor. The bearing extractor is characterized in that a cross beam is included, support screws are arranged at two ends of the cross beam, two adjusting nuts are assembled on the support screws and on the upper and lower end faces of the cross beam, a T-shaped stud is penetrated in the middle of the cross beam, an adjusting nut is assembled on the T-shaped stud, pipe threads are arranged at two ends of the T-shaped stud, ejector rods are arranged at the two ends of the T-shaped stud in a threaded mode, and the ends of the ejector rods are in ball structures. The bearing extractor is simple in structure, convenient to use, easy to produce, low in cost and the like; and additionally, the working efficiency is greatly improved, the labor intensity is reduced, and secondary destroy is not generally caused during extraction.
Description
Technical field
The utility model belongs to the equipment Repairing Technology field, particularly relates to a kind of shaft bearing replacer.
Background technology
In machining industry, a lot of places all need bearing, and bearing belongs to wear-out part, therefore regularly need to overhaul and change, when maintenance and replacing, the dismounting bearing is absolutely necessary, and comes institute for the maintenance personal, the general employing beaten, and the modes such as recoil are pulled down bearing, time-consuming so again effort.When sometimes needing to overhaul, detaching equipment, bearing do not damage originally, after dismantling through this mode, have become waste product yet.In addition, sometimes in order to dismantle a bearing, equipment significantly need to be dismantled, so not only labour intensity is large, but also affects maintenance efficiency.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, shaft bearing replacer of improving maintenance efficiency for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of shaft bearing replacer, it is characterized in that: described this stripping attachment comprises crossbeam, two ends at crossbeam are separately installed with studdle, be fitted with respectively two adjusting nuts on the described studdle, two adjusting nuts are positioned at the up and down both ends of the surface of crossbeam, and described crossbeam centre position is coated with T font double-screw bolt, be fitted with adjusting nut on the T font double-screw bolt, the T prefix two ends of described T font double-screw bolt are respectively equipped with gas thread, and the two ends of described T prefix are screwed with push rod, and the end of described push rod is ball head structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, when reality maintenance and dismounting bearing, greatly increase work efficiency, reduced labour intensity, and when dismounting, substantially can not cause secondary to destroy, in addition, the utility model also have simple in structure, easy to use, be easy to make, the advantage such as with low cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is that the utility model uses state diagram.
Among the figure: 1, crossbeam; 2, studdle; 3, adjusting nut; 4, T font double-screw bolt; 5, adjusting nut; 6, push rod; 7, bearing outer ring.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 to Fig. 3, a kind of shaft bearing replacer, described this stripping attachment comprises crossbeam 1, be separately installed with studdle 2 at the two ends of crossbeam 1, be fitted with respectively two adjusting nuts 3 on the described studdle 2, two adjusting nuts are positioned at the up and down both ends of the surface of crossbeam 1, described crossbeam 1 centre position is coated with T font double-screw bolt 4, be fitted with adjusting nut 5 on the T font double-screw bolt, the T prefix two ends of described T font double-screw bolt are respectively equipped with gas thread, the two ends of described T prefix are screwed with push rod 6, and the end of described push rod is ball head structure.
At first the inner ring with bad bearing takes off, and workpiece and bad bearing outer ring 7 are placed on the workbench together.Regulate adjusting nut 3, make integral body reach suitable height.Regulate adjusting nut 5 and push rod 6, make push rod 6 tops can put into bad bearing outer ring, and then regulate push rod 6 tops, two tops are all fixed in the outer ring draw-in groove of bad bearing.Turn at last part adjusting nut 5, adjusting nut 5 is moved down at T font screw rod, shift out from workpiece thereby drive push rod 6 tops stick bad bearing outer ring, finish the dismantlement work of bad bearing.
The advantages such as the utility model is increased work efficiency greatly in sum, has reduced labour intensity, and substantially can not cause secondary to destroy in when dismounting, and in addition, that the utility model also has is simple in structure, easy to use, be easy to make, with low cost.
