What Is a Radial Drill?

Radial (English radial direction) refers to the direction of passing through the axis line in the radial plane. In bearing terms, there is usually radial clearance, radial plane, etc. A straight direction along the diameter or radius, or a straight direction perpendicular to the axis.

Radial (jìng xiàng) refers to the direction along the radius. Vertically I-shaped (straight). A straight direction along the diameter or radius, or a straight direction perpendicular to the axis. On the ground surface, it usually refers to the direction of a straight line passing through a point on a tangent plane with a point as the center point. In radio navigation or radio measurement, it refers to the direction of magnetic field lines extending through a center point (line). Literally, "radial" means "always." It means the direction of passing the axis line in the radial plane. In bearing terms, there is usually radial clearance, radial plane, etc. ^[1]

The radial direction is relative. For example, an axis must have an axis center. If there is an axis center, there is the center line of the axis center. Any direction perpendicular to the center line of the axis can be called radial direction. On the ground surface, it usually refers to the direction of a straight line passing through a point on a tangent plane with a point as the center point. In radio navigation or radio measurement, it refers to the direction of magnetic field lines extending through a center point (line).

Radial difference between radial and axial

1. Radial is the straight direction along the diameter or radius, or the straight direction perpendicular to the axis. On the ground surface, it usually refers to the direction of a straight line passing through a point on a tangent plane with a point as the center point. In radio navigation or radio measurement, it refers to the direction of magnetic field lines extending through a center point (line).

2. The axial direction is usually for cylindrical objects, that is, the direction of the central axis of rotation of the cylinder, that is, the common direction with the central axis. The "radial" is perpendicular to the "axial", that is, the radius or diameter direction of the end face circle of the cylinder. Radial and axial space are perpendicular. This concept is also used in physics to analyze the force or motion of an object. ^[2]

Radial radial stiffness

Radial stiffness is the force required to produce a unit deformation in the radial direction of a rigid component such as a main shaft, a bearing, or a screw. Stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to a force. It is a characterization of the difficulty of elastic deformation of materials or structures. The stiffness of a material is usually measured by the modulus of elasticity E. In the macro-elastic range, stiffness is a proportionality factor that is proportional to the part load and displacement, that is, the force required to cause a unit displacement. Its reciprocal is called flexibility, which is the displacement caused by a unit force. Stiffness can be divided into static stiffness and dynamic stiffness.

Radial radial load

The direction parallel to the axis is called the axial direction; the direction perpendicular to the axis (the same direction as the diameter) is called the radial direction. The pulley of the motor pulls the belt, and the motor is subjected to radial load. When the lathe drills a large hole sandwiching the workpiece, the lathe spindle is subjected to the axial load.

Radial radial dimension

The radial dimension refers to the diameter or the length in the radial direction, but not only the arc line can also have the radial dimension.

Radial radial clearance

Bearing clearance is also called bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not mounted on the shaft or the bearing box, one of its inner or outer ring is fixed, and then the unfixed one of the bearing is moved radially or axially. . According to the moving direction, it can be divided into radial clearance and axial clearance. The maximum amount of movement in the radial direction is called radial clearance, and the maximum amount of movement in the axial direction is called axial clearance. Generally, the larger the radial clearance, the larger the axial clearance, and vice versa.
