Abstract
The utility model discloses a detacher for an outer housing of a needle roller bearing, which belongs to the fast detaching tool technique field of the needle roller bearing outer housing. The utility model consists of a drawing body and a drawing head, one end of the drawing body is connected with the drawing head, the middle part is a column shape body, and a sleeve is arranged on the middle column shape body of the drawing body. One side of the drawing head is an inclined plane, and the outside diameter of the drawing head is longer than the inside diameter of a lug boss on the bearing outer housing and is shorter than the inside diameter of a raceway of the needle roller. The utility model adopts a set of needle roller bearing outer housing fast detaching device combined by the drawing body and the drawing head, and has advantages of simple structure, convenient operation, fast detaching of the needle roller bearing outer housing without demounting of the bearing pedestal and improved changing efficiency of the needle roller bearing by multiple times.
Description
Technical field
The utility model relates to the quick extracting tool of a kind of needle bearing shell, specifically a kind of needle bearing shell quick-release arrangement.
Background technology
We know, in the machine maintenance process, often run into the work of changing needle bearing, needle bearing is owing to be that the inside and outside shell separated structures is that inner casing can detach from shell with axle, thus when this damage of bearings often the rolling element of bearing (needle roller) scatter, inside and outside shell is damage not.Inner casing is embedded on the axle, is very easy to change.And shell is embedded in the hole of bearing block, if bearing block is removed easily, changes bearing shell ratio so and is easier to.Under considerable situation, bearing block also is not easy dismounting, for example bearing block weight more greatly or on every side the more situation step of parts just be not easy dismounting.Moreover, even dismounting easily also can take the regular hour.So, except bearing block is removed from the opposite direction of assembling the bearing shell pound out come, can also adopt and utilize electric tool that the method that shell rubs is taken out shell.But be to use in this method, both required the cutting tip of electric tool can stretch in the bearing shell, but also be not ground to the endoporus of bearing block when will guarantee to rub shell.So when work, should prepare each type electric tool and cable hank, careful when cutting again, be not optimal method.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate, the stripping attachment that is used for the needle bearing shell that can increase work efficiency.
The utility model is achieved through the following technical solutions:
The utility model is made up of drawing body and drawing head, is column in the middle of the described drawing body, and the one end is connected with the drawing head, and the other end is provided with boss, and the middle column body of drawing body is provided with sleeve.
The first side of described drawing is the inclined-plane, and the external diameter of drawing head is greater than the internal diameter of bearing shell convex platform and less than the internal diameter of needle roller raceway.Described sleeve two ends are provided with projection.
The utility model adopts by drawing body and drawing head and is combined into a cover needle bearing shell quick-release arrangement, principle according to pin removal drawing cylinder alignment pin, make special drawing device, the boss for the needle roller location that utilizes the needle bearing shell itself to have is the both sides projection of needle roller raceway, is drawing body location.The drawing head outside is the inclined-plane and is convenient to fill in the bearing shell, drawing head plane structure then is in order to contact with the boss of bearing shell when the drawing, need not dismantle bearing block like this, only needle roller in the bearing shell and retainer need be cleaned out, then drawing device is put into the bearing shell, utilize the boss in the bearing shell to block the drawing head, just can take out the bearing shell as the drawing alignment pin then.The utlity model has simple in structurely, easy to operate, can under the situation of not dismantling bearing block, finish the dismantlement work of needle bearing shell rapidly, significantly improve the advantage of changing needle bearing efficient.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1, the drawing body, 2, the drawing head, 3, sleeve.
The specific embodiment
Embodiment: as shown in the figure, the utility model is made up of drawing body 1 and drawing 2, is column in the middle of the drawing body 1, and one end and drawing 2 is connected, and the other end is a handle, and the middle column body of drawing body 1 is provided with sleeve 3.Drawing 2 outside are the inclined-plane, and drawing 2 one side that contact with sleeve 3 are the plane, and the external diameter of drawing head is greater than the internal diameter of bearing shell convex platform and less than the internal diameter of needle roller raceway.Described sleeve 3 two ends are provided with projection.
When the utility model uses, need not dismantle bearing block, only needle roller in the bearing shell and retainer need be cleaned out, then drawing device is put into the bearing shell, utilize the boss in the bearing shell to block the drawing head, when the sleeve on the pulling drawing body clashes into drawing once, because the drawing head has blocked the boss on the bearing shell, thereby pull out the bearing shell is piecemeal, just as the drawing alignment pin just can take out the bearing shell.
Claims (3)
1. being used for the stripping attachment of needle bearing shell, it is characterized in that, be made up of drawing body and drawing head, is column in the middle of the described drawing body, and the one end is connected with the drawing head, and the other end is a handle, and the middle column body of drawing body is provided with sleeve.
2. the stripping attachment that is used for the needle bearing shell according to claim 1 is characterized in that, the first side of described drawing is the inclined-plane, and the external diameter of drawing head is greater than the internal diameter of bearing shell convex platform and less than the internal diameter of needle roller raceway.
