The bearing pressing-in device disclosed by the utility model has the beneficial effects that the pressure of an oil press is conveniently applied, and no damage to the bearing is caused; and the bearing pressing-in device has the advantages of simple structure, easiness in manufacturing, convenience in use, and the work efficiency can be effectively improved.
Description
Technical field
The utility model relates to a kind of bearing press-in device, relates to a kind of bearing press-in device that under the pressure of hydraulic press, uses in particular.
Background technology
In the installation process of component of machine, often running into will be with pack into the situation of axle of bearing, usually; Described axle has a cylindrical part and a tapering part that is arranged on the cylindrical part, and bearing then is an annulus, need it be set in the tapering part bottom of axle; Contact with cylindrical part, and, in the frock process, need very great dynamics because need combine closely between bearing and the axle; But, because bearing holder (housing, cover) is connected on the tapering part of axle, so; The pressure of hydraulic press is difficult to apply, if exert pressure from the side, then easily bearing is damaged.
The utility model content
Be to solve the deficiency of prior art, the purpose of the utility model is the bearing press-in device that provides a kind of pressure of being convenient to hydraulic press to apply and bearing is not damaged.
For achieving the above object, the utility model is to realize through following technical scheme:
A kind of bearing press-in device comprises guide part and exerts pressure portion that the described guide part and the portion of exerting pressure are the cylinder of hollow; Guide part is positioned at the bottom of the portion of exerting pressure; Be integral structure, the internal diameter of the described portion that exerts pressure cooperates with the maximum outside diameter of the tapering part of axle, and the internal diameter of described guide part cooperates with the external diameter of described bearing; And the internal diameter of described guide part is greater than the internal diameter of the portion of exerting pressure; Internal connection in the guide part and the portion that exerts pressure forms step surface, and in addition, the height of described guide part is less than or equal to the height of bearing.
In order after accomplishing the bearing frock, to make things convenient for bearing press-in device to take out, the top of the described portion that exerts pressure also is horizontally arranged with a pull bar.
Pressure for the ease of hydraulic press is applied to the device for exerting top, and described pull bar is embedded in the inside top of the said portion that exerts pressure.
The beneficial effect of the utility model is: the described a kind of bearing press-in device of the utility model; Through guide part and the step surface that forms between the portion of exerting pressure bearing is exerted pressure; Be convenient to the pressure pressing of hydraulic press and can not damage bearing; And, pull bar has been installed, make things convenient for bearing to be pressed into portion in the taking-up of accomplishing after bearing is pressed into work; The utility model is simple in structure, makes easily, and is easy to use, can effectively increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the profile of the utility model one embodiment;
View when Fig. 3 is the completion bearing frock of the utility model one embodiment.
The main mark implication is following in the accompanying drawing:
1, pull bar 2, the portion 3 that exerts pressure, guide part 4, axle.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Embodiment 1:Fig. 1 is the structural representation of the utility model one embodiment; Fig. 2 is the profile of the utility model one embodiment.
Like Fig. 1, shown in Figure 2: a kind of bearing press-in device, comprise guide part 3, exert pressure portion 2 and pull bar 1, said guide part 3 is one-body molded with the said portion 2 that exerts pressure.
Said guide part 3 is the cylinder of hollow, is positioned at the bottom of the portion of exerting pressure 2.The internal diameter of described guide part 3 cooperates with the external diameter of described bearing, and the internal diameter of described guide part 3 is greater than the internal diameter of the portion of exerting pressure 2, forms step surface in the internal connection of the guide part 3 and the portion 2 that exerts pressure, and said step surface is directly exerted pressure to bearing.In addition, the height of described guide part 3 is less than or equal to the height of bearing.In the present embodiment, the height of said guide part 3 equates with the height of bearing.Said guide part 3 sockets and the bearing outside, the direction of motion of pilot bearing and protection bearing are not damaged bearing under the pressure status.
The said portion 2 that exerts pressure is the cylinder of hollow, is positioned at the top of guide part 3, and the internal diameter of the described portion 2 that exerts pressure cooperates with the maximum outside diameter of the tapering part of axle 4.The said portion 2 that exerts pressure is free to move up and down at the tapering part of axle 4, does not receive resistance.
Said pull bar 1 is horizontally set at the top of the portion of exerting pressure 2, and is embedded in the inboard, top of the said portion 2 that exerts pressure, and after accomplishing the bearing frock, makes things convenient for bearing press-in device to take out.
During the work of the described bearing press-in device of present embodiment, earlier axle 4 is placed on the hydraulic press platform, bearing holder (housing, cover) is connected to the tapering part of axle 4, again the bearing portion of being pressed into is socketed on the tapering part of axle 4, its guide part 3 is socketed on the bearing.Start hydraulic press, bearing press-in device is exerted pressure, the step surface of the portion 2 that exerts pressure is pressed into axle 4 with bearing, and the view of accomplishing frock is as shown in Figure 3.After accomplishing frock, the turbine shutdown oil pressure machine is held pull bar 1 and is upwards mentioned, and takes out bearing press-in device.
Said bearing press-in device is exerted pressure to bearing through the guide part 3 and the step surface that forms between the portion 2 of exerting pressure, and the pressure of being convenient to hydraulic press applies and can not damage bearing.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
