Imported bearing type choose several factors

Here we’d like to talk about Imported bearing type choose several factors.
1, bearing radial load
Mainly bear radial load bearing for centripetal bearing. This type of bearing the nominal contact Angle of a0 < = 0, 45. Size of the same roller bearing is larger than the ball bearing can bear radial load.
N and NU type cylindrical roller bearing can bear radial load, other types of centripetal all kind of size of Taper roller can bear radial load, can also carry axial load.
2, bearing axial load
Mainly bear axial load of bearing, generally for the thrust bearing, its nominal contact corner a0 > 450. Thrust bearing and thrust angular contact ball bearing according to the different structures can take one or two directions at the same time of axial force. When bear particularly high force optimization with thrust cylindrical roller bearings, thrust spherical roller bearings.
Thrust spherical roller bearings and one-way thrust angular contact ball bearings can carry axial load and radial load at the same time, other thrust bearing can only carry axial load.
3, the length of the bearing their own compensation
A shaft bearing and imported bearing usually adopt fixed bearing and floating bearing structure. The length of the winding shaft bearing compensation error and thermal expansion.
NU type and swimming N type cylindrical roller all kind of parameter of TIMKEN bearing are the ideal bearing, the bearing itself can compensate for length. Bearing inner and outer circle can use a tight fit.
The length of the sliding fit compensation
Integral bearing (such as deep groove ball bearing and spherical roller bearing) can also be swimming bearings. This kind of imported bearing with a use of the two ring, no axial fixed surface. Therefore, bearing a ring can be the supporting surface activity.
4, separable bearing (accuracy)
This is a kind of bearing ring can be installed in a separate, when both ring with tight fit its advantage is very outstanding.
Separable bearings include four-point contact ball bearing, two and a half circle of double row angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, thrust ball bearings, thrust cylindrical roller bearings, thrust spherical roller bearings.
Here also introduce the integral imported bearing type:), a integral bearing: deep groove ball bearings, single row angular contact ball bearings, self-aligning ball bearings, peng roller bearings and spherical roller bearings.
In most cases the application of the general size and rotating precision of the rolling bearing is enough. When demand higher, bearing need higher precision grade, (such as spindle bearing).
5, no neutral compensation
Not neutral in machining shaft neck surface or bearing with surface, especially with surface processing is not done in the middle of a pack card. Also can produce wrong, when using bearing seat (for example: flange bearing or vertical bearing). Due to work load bending deformation in the shaft, which can lead to bearing inner and outer circle, also can appear in the wrong.
Self-aligning bearing can undertake compensation right and inclination, for example:, peng roller bearings, self-aligning ball bearing radial and thrust spherical roller bearings. This kind of bearing has a concave spherical outer ring raceway, rolling body and inner ring can rotate inside. These compensation axis deflection Angle at the centre of the bearing capacity depends on their own type, size and load conditions.
Spherical bearing and outdide circle of thrust ball bearing has a spherical bearing surface: when installed in the hollow spherical seat can be adjusted to compensate deflection Angle.
Single bearing friction especially low, so can reach maximum speed. Such import bearing can bear radial load of deep groove ball bearing and angular contact ball bearings can withstand the combined load.
Improve the dimensional precision, rotating precision of the bearing and cooperate with the precision of the parts, the lubrication cooling way, using a special form of cage can improve bearing allows speed.
Low noise in a small motor operation, office equipment and household appliances and other general requirements to’s running noise.
6, conical hole
Imported bearing with conical hole can be installed directly to the cone shaft neck (for example: high precision structure of single row and double row cylindrical roller bearing). When installing this kind of bearings can adjust out of a given radial clearance.
Most with a conical bore self-aligning ball bearings, cylindrical roller bearings and spherical roller bearings are available through a set of installation set to the cylindrical shaft neck. This type of bearing special is easy to install and remove.
7, stiffness
Imported bearing stiffness is usually directed bearing the force needed to produce certain elastic deformation. Machine tool spindle and pinion shaft bearings are required to have high stiffness. As a result of the rolling element and raceway contact condition is different, the rigidity of the roller bearing is higher than the stiffness of ball bearing.
8, friction
Except by heating and cooling, the internal friction of bearing working temperature also plays a big decision. Low friction import bearings are: bear radial load of deep groove ball bearings, single row angular contact ball bearings and cylindrical roller bearings with cage. Contact sealed bearings, full of cylindrical roller bearings, thrust roller bearing can produce greater friction.

Object Oriented Application Development I: ITSD322 – 1304B – 01

“Create a class called “AnimalInfo” as the main class for the program.Create a class called “Animal” with a virtual method displayInfo().Create 3 classes inherited from Animal (one for each of your animals). Each of the inherited classes should override Animal.displayInfo() to display information about the animal. The information should just be a short description of the animal displayed to the screen.In the AnimalInfo.main() method, display a menu allowing the user to choose 1 of 3 animals or quit the program. The menu should accept input from the user and take the appropriate action and then repeat until the user selects the option to quit. Hint: Simple menus are easiest to implement if the user selects a letter or number for each menu item.When the user selects an animal, use the displayInfo() method of the appropriate class to display information about the selected animal.Use comments throughout your code demonstrating your understanding of each statement of code.Make sure the program runs correctly before submission.Create a zip that includes your project folder and Word document, and upload it to the course portal.
