The installation for 22340 CA/ W33C3 Crusher machine Bearing

The Spherical roller bearing is arranged between the inner ring of two raceway and the outer ring of the ball, and the bearing with drum roller is assembled. The curvature center of the raceway surface is consistent with the bearing center, so it has the same tuning function as the Spherical ball bearing.

When bending the shaft and the shell, the axial load can be adjusted automatically and in two directions. Radial load capacity is large, suitable for heavy load and impact load. The inner diameter of the inner ring is the bearing of the taper hole, which can be installed directly. Or use a compact sleeve and remove cylinder on the cylinder shaft. Maintain frame with sheet metal stamping, polyamide forming cage and copper alloy car.

 

 

For the self-Spherical bearing, when bearing the bearing of the bearing shaft into the box shaft hole, the middle mounting ring can be used to prevent the outer ring from tilting and rotating. It should be remembered that some of the ball bearings with self-Spherical ball bearings protrude from the side of the bearing, so the central mounting ring should be concave to prevent damage. A large number of bearings are usually installed by mechanical or hydraulic pressure.It is better to use the core shaft to install the outer ring roller bearing.

For separable bearings, the inner and outer rings can be separately mounted so that the installation process is simplified, especially when the inner and outer rings need to be combined. When the inner ring has been installed into the bearing box containing outer ring, it is necessary to check whether the inner and outer rings are correct to avoid the bearing raceway and rolling parts. It is recommended to use the mounting sleeve if the cylinder and needle bearings have inner rings with flange edges without flange. The outer diameter of the sleeve should be equal to the inner ring diameter F, and the tolerance standard for machining should be d10.

The Spherical roller bearing is arranged between the inner ring of two raceway and the outer ring of the ball, and the bearing with drum roller is assembled. The curvature center of the raceway surface is consistent with the bearing center, so it has the same tuning function as the Spherical ball bearing.

When bending the shaft and the shell, the axial load can be adjusted automatically and in two directions. Radial load capacity is large, suitable for heavy load and impact load. The inner diameter of the inner ring is the bearing of the taper hole, which can be installed directly. Or use a compact sleeve and remove cylinder on the cylinder shaft. Maintain frame with sheet metal stamping, polyamide forming cage and copper alloy car.

For the self-Spherical bearing, when bearing the bearing of the bearing shaft into the box shaft hole, the middle mounting ring can be used to prevent the outer ring from tilting and rotating. It should be remembered that some of the ball bearings with self-Spherical ball bearings protrude from the side of the bearing, so the central mounting ring should be concave to prevent damage. A large number of bearings are usually installed by mechanical or hydraulic pressure.

For separable bearings, the inner and outer rings can be separately mounted so that the installation process is simplified, especially when the inner and outer rings need to be combined. When the inner ring has been installed into the bearing box containing outer ring, it is necessary to check whether the inner and outer rings are correct to avoid the bearing raceway and rolling parts. It is recommended to use the mounting sleeve if the cylinder and needle bearings have inner rings with flange edges without flange. The outer diameter of the sleeve should be equal to the inner ring diameter F, and the tolerance standard for machining should be d10.

It is better to use the core shaft to install the outer ring roller bearing.

 

Clearance 22320CA/W33 Crusher machine Bearing

For the mounting axial clearance of the aligning roller bearing, adjust the screw on the shaft neck, adjust the thread of the gasket and bearing hole, or use the extension spring method. The size of the axial clearance is related to the arrangement of the bearing installation, the distance between the bearings and the material of the bearing seat, which can be determined according to working conditions. For high load high speed of spherical roller bearing, adjust clearance, must consider the effect of temperature on the axial clearance, clearance reduction is estimated, will cause the temperature rise, that is to say, the axial clearance to properly adjust a bit bigger. For bearings with low rotating speed and bearing vibration, there should be no gap mounting or preload mounting. The purpose is to make the roller and raceway of the aligning roller bearing good contact, the load evenly distributed, to prevent the roller and raceway from being damaged by the vibration shock. After adjustment, the axial clearance size is tested with a micrometer. The method is to fix the micrometer on the fuselage or the bearing pedestal, so that the micrometer can touch the surface of the polished surface of the shaft and push the axis along the axis, and the maximum pendulum momentum of the dial is the axial clearance value.

Pay attention to the problem

Self-aligning roller bearing pre-tightening force is carried out at room temperature, but is in working status, system micro tensile temperature rise of the drive shaft, bearing preloaded force change, therefore, set the pre-tightening force, this factor should be considered.

It requires the ability of the size, speed, and other conditions to set reasonable use of the aligning roller bearing preload to ensure the transmission of life. If pretension is too large, power consumption, even lead to overheating. If the pre-tightening force is too small, body load, axial rolling, outer ring, under the action of the gap between the beating, run, transmission precision, in order to reduce the noise increased, affect the gear mesh, serious damage, the teeth and bearings.

According to different aligning roller bearing assembly, for example, the bearing pre-tightening nut is rotated directly from the axial compression inner bearing inner ring, and the inner and outer rings are used to eliminate the gap and realize the purpose of bearing prestressing force. Realize common use: first, far more than the preloaded bearing, the nut finally, and then back 1/4 turn. Assembly method, the advantage of this method is less investment, simple, practical, consistent good quality of the premise of tapered roller bearings, it can be used.

1. Electric heating method Place the bearing on the electric hot plate temperature of 100 ℃ for a few minutes, this method is most convenient, such as reverse it a few times can make the bearing heated evenly, and the efficiency is high, resize roller bearing can use this method.

2. The heating method of electric furnace is used to heat the bearing in the closed automatic temperature control furnace. The heating is even, the temperature control is accurate, the heating is fast, and it is suitable for a batch of heated bearings.

3. The induction heating method using induction heater can be fast, reliable and clean will be heated to the required temperature spherical roller bearing, which are particularly suitable for the inner ring of the tight fit, just because of the heated inner ring, and the outer heat is small, so can be a drag on the shaft, also easily into a hole.

4. Light bulb heating heating method using 50 w bulb spherical roller bearings, can guarantee the heating temperature about 100 ℃, the smaller the bearing can be directly on the bulb, larger bearing cone enclosure may be placed on a light bulb, conical cover can prevent heat losses, light bulbs and uniform heating cone cover can be adjusted up and down, in a certain heating range that can adapt to different size of bearing using infrared light bulb, pay attention to the direction of light bulbs should be down, in order to avoid this kind of bulb of infrared radiation is bad for the eyes can be energy-saving bulb heating method is suitable for small and often do not need; In the case of bearing heating, the light bulb can be used for illumination, and no other equipment is required.

5. Oil tank heating method This is a widely used traditional heating method, the bottom of the tank from 50 to 70 mm in the metal mesh, bearing on the Internet, large bearing to hoist hooks in the bearing should not be placed directly on the bottom of the channel, in case of contact with the bottom of the channel bearing parts of the local heat is too high, or the bottom of the channel deposition of dirt into the bearing oil tank heating method of key points are as follows, should use no corrosive thermal stability good mineral oil, transformer oil, it is best to oil and the capacity of the container should be kept clean oil tank should be heated and spherical roller bearing and the size of the oil, if the container is too small, in continuous operation, one into the bearing oil temperature will drop quickly, the effect is bad
