What is the axis refers to the truck? Single bridge, double bridge, four after four, eight after the first four, semi-trailer, two up three, three up three: what do you mean?
A revolving part of a machine is mounted on a shaft. Depending on the shape of the shaft, the shaft can be divided into two types: crankshaft and straight shaft. According to the bearing of the axle, it can be divided into: (1) rotating shaft, when it is working, it takes both the bending moment and the torque. It is the most common shaft in the machine, such as shafts in various reducers. The spindle is used to support the rotating parts, only to bear the bending moment, but not to transfer the torque. Some spindles rotate, such as the axle of the railway vehicle, etc. Some spindles do not rotate, such as the shafts of the supporting pulleys. The drive shaft is mainly used to transfer torque and bearing moment, such as the long axis, the automobile crane moving mechanism in the drive shaft. The shaft material is mainly made of carbon or alloy steel, or ductile iron or alloy cast iron. The working capacity of the shaft generally depends on the strength and stiffness, and the high speed also depends on the stability of the vibration.
Mathematics is a straight line, around which the point revolves around it, or uses it as a criterion for determining the position of each point: the axis of rotation and the axis of coordinates.A term of tolerance and coordination, usually of cylindrical outer surface of a workpiece, including a non cylindrical outer surface (an enclosed surface formed by two parallel planes or planes).
A mechanical part that rotates and rotates with it to convey motion, torque, or bending. Generally round metal rods, each segment may have different diameters.
