Background technology
Current bearing is one of most commonly seen mode of rotation connection in industrial equipment, is also the portion for being easiest to damage
Part, and most flimsy position be bearing groove in ball come off, the mode of conventional dismounting bearing is to be dismantled by drawing horse,
Or cut by gas welding, because the operating space for drawing horse dismounting needs enough could draw grasping for horse to be positioned over bearing inner race
Bearing, and many equipment does not have suitable operating space so that draw the horse cannot to use, and cut by gas welding or other are cut
Mode is cut, more inconvenience is often operated, and needs operative skill higher, otherwise easy damaged bearing fixed position, be bearing peace
Dress hides some dangers for.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of adjustment type bearing disassembling device, can be easily right
Dismantled with fluted bearing, it is possible to the size according to bearing carry out drag hook with changing the tune with whorl brace rod position
Section.
The utility model is achieved through the following technical solutions：
A kind of adjustment type bearing disassembling device, including threaded mandrel, also including the support bar being threadedly coupled with threaded mandrel,
Support bar positioned at threaded mandrel both sides is provided with groove, and the threaded mandrel end diameter is threaded portion less than threaded mandrel
The diameter for dividing, respectively tapered abutting end, foursquare force side, whorl brace rod is through groove by nut and support
Bar is fixedly connected, and the end that the whorl brace rod is located at the abutting side of threaded mandrel is connected with inverted " t " type drag hook.This reality
Be with new further improvement project, the T-shape drag hook, including horizontally set chock, vertically arranged connecting rod, the plug
Block widest part width is less than the most narrow space between bearing outer ring to be torn open and inner ring from most strong point length is less than and tears bearing outer ring groove open
Between inner ring groove longest distance, be less than spiral shell from, the connecting rod diameter more than the most narrow space torn open between bearing outer ring and inner ring
Line connects shank diameter, and the connecting rod diameter is identical with chock widest part width.The further improvement project of the utility model is, institute
Chock is stated for oval metal block, vertical welding is in interlinking lever end.
The further improvement project of the utility model is that the connecting rod is provided with external screw thread, the whorl brace rod and connecting rod
Connection end is provided with axial groove, and the internal thread matched with the external screw thread on connecting rod is provided with the groove.
The further improvement project of the utility model is that the end that the whorl brace rod is located at threaded mandrel force side sets
Have square.
The further improvement project of the utility model is that the groove is symmetricly set in support bar centered on threaded mandrel.
The utility model has the following advantages that,
First, structure is relatively simple, in that context it may be convenient to size adjustment whorl brace rod according to bearing on support bar
Fixed position, it is ensured that drag hook can be located at surface between bearing outer ring to be torn open and inner ring.
2nd, can adjust whorl brace rod and stretch out the length of support bar, so as to ensure according to the installation site of bearing to be torn open
Threaded mandrel pushes against end and can suitably push against Support Position.
3rd, whorl brace rod one end is set to square force side, is exerted a force when facilitating demounting bolt（Turned by spanner
Dynamic threaded mandrel）.
The 4th, whorl brace rod and connecting rod are set the threaded connection for cooperating, it is ensured that can be according to the big of bearing to be torn open
It is small to change suitable drag hook.
5th, chock is set to the oval rotation for facilitating chock, makes that chock is more convenient to be turned at the groove of bearing
It is dynamic.
6th, whorl brace rod is provided with square in the end of threaded mandrel force side, it is convenient by drag hook insertion axle
Rotated after holding, it is ensured that drag hook can catch on the groove between the inside and outside circle of bearing.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is structural representation at drag hook insertion bearing groove.
Specific embodiment
As shown in Figure 1 and 2, a kind of adjustment type bearing disassembling device, including threaded mandrel, also including with threaded mandrel screw thread
The support bar of connection, the support bar positioned at threaded mandrel both sides is provided with groove, and the threaded mandrel end diameter is less than screw thread
Push rod is threaded the diameter of part, and respectively tapered abutting end, foursquare force side, whorl brace rod pass through groove
It is fixedly connected with support bar by nut, the end that the whorl brace rod is located at the abutting side of threaded mandrel is connected with down
T-shape drag hook.The T-shape drag hook, including horizontally set chock, vertically arranged connecting rod, the chock widest part width
Less than the most narrow space between bearing outer ring to be torn open and inner ring from, most strong point length less than tear open bearing outer ring groove and inner ring groove it
Between longest distance, more than the most narrow space torn open between bearing outer ring and inner ring from, the connecting rod diameter less than threaded connection shank diameter,
The connecting rod diameter is identical with chock widest part width.The chock is oval metal block, and vertical welding is in interlinking lever end.Institute
State connecting rod and be provided with external screw thread, the whorl brace rod is provided with axial groove with the connection end of connecting rod, be provided with the groove with
The internal thread that external screw thread on connecting rod matches.The end that the whorl brace rod is located at threaded mandrel force side is provided with just
