How do you remove the bearing sleeve on the rotor?

With two large slotted cones at the same time, you can take it down.

Bearing: Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger, and the highest is also higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. It mainly has an outer ring, an inner ring, and a rolling element, which can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

Two methods:1Heating the inner sleeve, it is best not to use gas welding to heat, the damage to the shaft is relatively large, the specific method depends on what you have on site. Master the following principles; 1.Don't brute-force the shaft; 2.Do not overheat and cause changes in the metallographic structure of the shaft.

2.Freeze the shaft: Freeze the shaft with dry ice and remove the inner ring.

If the interference of the inner ring and the shaft is not large, and the inner ring is not removed, then directly weld two screws on the inner ring, and then use tools to force on the screws to remove the inner ring. Look at your shaft is not too thick, the interference should not be too large, this method is feasible, hehe!

I've had this kind of problem, and here's how I deal with it: use a hand grinder to cut the inner sleeve loose without damaging the rotor, and then shave it back and forth with the cub.

1；There is a hand grinding wheel to grind off.

2；Spray the loosening agent, clamp the rotor with a vise, and unscrew it with a pipe wrench.

The methods of removing the inner ring of the bearing include the half-shaft method, the horizontal and vertical method of the iron plate, the oblique hitting method of the iron rod, the flat screwdriver method, and the heating method.

1. Half-axis method.

The two steel balls that damage the rolling element of the bearing together with the inner ring on the half shaft are symmetrically and evenly distributed in the outer ring of the bearing, and at the other end of the half-hungry shaft casing, a slightly thicker hard wood block is padd, and the wooden block at the spline end of the half shaft can be hit. (as shown in the image below).

2. Iron plate horizontal and vertical method.

The iron plate with a length of 50 cm, a width of 3 cm and a thickness of about 1 cm is placed in the outer ring of the bearing, and one person pries the outer ring of the bearing, and one person uses an iron rod against the iron plate to hit, and the corresponding direction of the iron plate is changed at any time. (as shown in the image below).

3. Iron rod oblique striking method.

From the other end, the iron rod is obliquely into the groove of the outer ring of the bearing, and the groove of the outer ring of the bearing is changed from time to time by hitting it with a hammer. (as shown in the image below).

4. Flat screwdriver method.

When the outer ring of the bearing and the half-shaft sleeve are matched due to wear, the outer ring of the bearing can be disassembled by prying on the left and right sides of the flat mouth screwdriver. (as shown in the image below).

5. Heating method.

The part around the half-shaft sleeve of the outer ring of the bearing is heated to expand when heated, and the outer ring of the bearing can fall off. (as shown in the image below).

Summary. Hello dear, happy to answer your <>

What to do if the inner sleeve of the bearing cannot be removed on the shaft: the solution is as follows: 1

The bearing can be removed from the housing along with the shaft and then removed from the shaft with a press or other dismounting tool. 2.The inner sleeve of the bearing is pressed up.

If you don't need this sleeve, weld a little on it and let it cool

What should I do if the inner sleeve of the bearing cannot be removed from the shaft.

Hello dear, I'm glad to answer for you [too happy to change the spring spike] <> bearing Nathan socks can't be removed on the shaft: the solution is as follows: 1

Hello <>

Give the bucket wheel your expansion as follows<>

1.The bearing is a part that supports the shaft, it can guide the bearing knowledge of the shaft to rotate, and it can also withstand the parts of the shaft overhead bridge bad rotation, 2Bearings can be divided into:

Rolling bearings and plain bearings, bearings refer to rolling bearings. 3.A bearing is a component that supports a shaft and is used to guide the rotational motion of the shaft

Summary. Hello dear, happy to answer for you About if the bearing inner sleeve is stuck on the shaft and cannot be removed, you can try the following methods:1

Lubricating oil can be sprayed between the bearing sleeve and the shaft, and then gently shaken to loosen the bearing sleeve. Do not use too much force to avoid damaging the shaft or bearing sleeve. 2.

If the bearing inner sleeve is very tight, some professional tools, bearing removers or slide hammers can be used to assist with removal. Extreme care is required to avoid injury or damage. 3.

You can also try to soak the contact surface between the bearing sleeve and the shaft with a rust inhibitor or detergent, and then disassemble it after it has fully penetrated, which can reduce friction and make disassembly easier.

4.In addition, you can use a heater: use a stove, spray gun and other tools to heat the inner sleeve of the bearing, and wait until its thermal expansion and contraction before disassembly, which can reduce the friction of the large fiber and make it easier to disassemble.

5.Soak in ice water: This allows the parts containing the bearing liner to be soaked in ice water to cool the bearing liner and shaft and allow it to shrink.

Then take it out and drain it, gently push the bearing sleeve, and it will usually be able to be removed smoothly.

1. Steel ball method: 3 steel balls or 4 steel balls and the inner ring in the damaged bearing rolling body are re-evenly distributed in the bend of the outer ring of the bearing, and from the other end of the half-shaft casing, use an iron rod slightly larger than the inner diameter of the bearing to tighten the inner diameter of the bearing, and hit it with a hammer. 2. Tire Law:

Restore the prototype of the bearing according to the steel ball method, and after installing the tires, tighten the half-shaft nut, but do not overtighten it. Shake the tire with both sides of the sledgehammer, or hold the tire with open arms and pump it back and forth vigorously. 3. Half-axis method:

The two steel balls that damage or destroy the rolling element of the bearing together with the inner ring on the half shaft are symmetrically and evenly distributed in the outer ring of the bearing, and at the other end of the half shaft casing, a slightly thicker hard wood block is padd, and the wooden block at the end of the half shaft spline can be hit. Hope it helps.

Now ordinary bearings, with cages (that is, fixed bearing rings) usually before putting in enough bearing balls, the cage is not yet, then after the ball is installed, the cage can be installed, because when there is no cage, the ball can be rolled to one side, so that the inner ring can be taken out.

As for the deep groove full of balls without cage bearings, usually in the inner ring, there is a small groove, the ball is loaded from here, after being installed, most of the bearings are glued with a metal sheet that is completely consistent with the groove, of course, there are also non-bonded, in fact, the ball has no way to come out, unless there is an external force, and if a metal sheet is bonded there, the ball is even more unlikely to come out.

At the same time, you can buy one yourself and take a look, you can still see the imprint of this glued place, and even some are not glued, just like that. As for the needle rollers. Angular contact with these bearings, basically, can be taken out casually.

There are no installation issues. The installation is mainly for the Type 2 bearings mentioned above.

With puller, the inner ring of the bearing is evenly stressed, which will not damage the bearing and affect the accuracy of the shaft.

Or use two half-rings to buckle the inner ring of the bearing, and press the bearing out with pressure, so that the bearing and shaft are not affected.

For the installation of bearings, the temperature should not exceed 100 degrees, and after half an hour after 100 degrees, the main hands should wear heat-insulating gloves to prevent burns. If there is no oven, you need to make a copper sleeve, the outer diameter of the copper sleeve is the same as the outer diameter of the inner ring of the bearing, the inner diameter is slightly larger than the shaft, and the outer end is closed to facilitate the bearing to be pressed into the latter hammer with the latter. There is no damage to the tolerance shaft before installation, and the burr is trimmed for easy installation.

First, confirm the bearing type and workpiece condition, and then select the corresponding disassembly tool; The same is true for installations, and the tools selected may sometimes vary depending on the bearing type. This information or solution is available on SKF**, there is no specific bearing model, I can only say so much.

The fit between the inner ring of the rolling bearing and the journal is an interference fit, and you can use a punch or hammer to push down the edge of the inner ring. Don't just knock a little when you knock.

The new bearing can be installed by heating it up a little before installation, and it is easier to install.

Pull out with a triangular target, when installing, you should pay attention to the thick plank when smashing, and when the plank can not be mated, use a hammer to smash the inner circle, and do not only smash one side of the force evenly.
