What is a rotary body in machinery, and what does a rotary body mean?

In mechanical drawing, the common rotary bodies are: cylinder, cone, and sphere. The elongation objects of the rotary body include three-dimensional objects such as conical tables and cylinders that are cut, grooved, and dug holes.

There are many concepts involved in the definition of a rotary body:1Rotary body definition:

A three-dimensional body composed only of a rotating surface or a rotating surface and a plane is called a rotating body. 2.Rotary Surface Definition:

A face formed by a line rotating around another line that is coplanar to it. 3.Axis:

The line that is rotated around is called an axis.

Other Extended Concepts:1Busbar:

A line that can be rotated around an axis. 2.Plain line:

A busbar at any position on the rotating surface. 3.Latitude circle:

The trajectory of any point on the bus is a circle, and this circle is called a weft circle. The plane in which the circle is located is perpendicular to the axis. 4.

Radius of the circle: The distance from any point on the bus to the axis.

These concepts help to understand the formation of a rotary body, assuming two points at both ends of an object, and the two points are connected in a line through the object, the object takes this line as the center of rotation, and each part of it rotates to a fixed position when it rotates to the same shape, this is a standard rotary body, which is characterized by symmetry on both sides of the center line, so the rotary body is basically symmetrical.

In the mechanical industry, the processing of rotary bodies is generally done by lathes.

For example, the earth is a rotating body, although it is not very standard.

Another example is the bullet, which is a standard rotary body.

Rotary body is a word to describe shape, not a dynamic word, that is, it does not have to be rotated to be called a rotary body.

A rotary body is a part that can be rotated with a flat element on a rotary axis. For example, cylinders, rings, and other parts with axes.

The rotary body is the part that can be machined by all lathes.

It is an object formed by rotating around a certain midline.

Shaft parts and wheel parts.

Rotary body, two points are assumed at both ends of an object, and the two points are connected in a line through the object, the object takes this line as the center of rotation, and each part of it rotates to a fixed position when it rotates to the same shape, which is a standard rotary body.

It is characterized by symmetry on both sides of the center line, so the rotary body is basically symmetrical. In the mechanical industry, the processing of rotary bodies is generally done by lathes. For example, the earth is a rotating body, although it is not very standard.

Rotary body is a professional term, that is, there is an object as the center of the fixed point, and then through a line in the center of the object, as the axis for a rotation, in the process of rotation each part rotates to a fixed position to form the shape is the same, the final shape of this is called a rotating body.

Common gyrators.

The above concept is more abstract, simply put, the gyroscope is a more evenly stacked three-dimensional shape of the object bending and rushing body, for example, our common cylinder, cone, sphere, etc., are oh, in life the gyroscope is also more common, but the shape requirements are more strict, such as bullet burial, shot put and other objects, so it is still easier to identify.

Bullet.

It consists of an axis and a radius of the circle of latitude.

1.Definition of rotary body: A three-dimensional body composed only of a rotating surface or a rotating surface and a plane is called a rotating body.

2.Gyratory surface definition: A polygon formed by a line rotating around another line that is coplanar to it.

3.Shaft: The line that rotates around the baffle is called an axis.

Other Divine Extension Concepts:1Busbar:

A line that can be rotated around an axis. 2.Blind round line:

A busbar at any position on the rotating surface. 3.Latitude circle:

The trajectory of any point on the bus is a circle, and this circle is called a weft circle. The plane in which the circle is located is perpendicular to the axis.

4.Radius of the circle: The distance from any point on the bus to the axis.

A rotary body is composed of a rotating surface or a rotating surface and a plane.

The rotary surface is a smooth surface formed by the fixed axis rotation motion of a certain line segment (called the bus bar of the rotary surface) around the linear line of space, and the line at any position of the bus bar on the rotating surface is called the plain line.

The rotary body is a three-dimensional enclosed by a rotating surface or a rotating surface and a plane, and the common rotating bodies are: cylinder, cone, sphere, etc.

It refers to a section that can be formed around an axis, called a rotary body, such as disc parts, automobile tires, etc.

The rotary body referred to in the project is a regular surface three-dimensional formed by the rotation of the bus around the axis of rotation The rotary body commonly used in the project is: cylinder, cone, ball and ring

I'm a mapping teacher. My answer is the standard answer.

Around a central axis, it can be rotated. Such as flanges, cylinders, etc.

You're talking about ** or geography.

Suppose two points at two ends of an object, and the two points are connected to form a line through the object, the object is the center of rotation with this line as the center of rotation, and each part of it rotates to a fixed position when it rotates to the same shape, which is a standard rotary body.

The hydraulic slewing joint has two layers: an inner cylinder and an outer housing.

The hydraulic oil is connected from the main control valve to the internal column, and the oil circuit of the travel motor is connected to the housing. The internal cylinder is cast with a circular groove (i.e., oil channel) from top to bottom; The outer housing is also equipped with a small groove corresponding to the groove (for mounting the swivel sealing ring).

When the machine is in rotational motion, the shell is fixed, and there is a relative motion between the internal cylinder and the shell (the cylinder rotates in the shell). Because the oil duct is circumferential, the machine can rotate arbitrarily within the circumference.

How do you ensure a seal? Of course, the sealing rubber ring on the housing is tightly connected to the cylinder, and they can be kept in relative rotation while contacting.

I guess it's hard for you to see the actual situation of the removal, the rotary joint oil seal is rarely replaced, and you have very few opportunities to go to the construction site.

It would be nice to know the principle.
