What are the components of a conventional mechanical system

Mechanical transmission systems include clutches, transmissions, universal drives, drive axles, and splitters.

Mechanical transmission system: is an important part of the composition of the machine tool, mainly by the ball screw for transmission, ball screw

in the transmission process of the screw and the movement of the axis is one, in Japan MAZAK also

machine tools are used as a drive motor.

The role of mechanical transmission: the role of mechanical transmission is to transfer motion and force, commonly used types of mechanical transmission systems are gear transmission, worm gear transmission, belt drive, chain drive, wheel system.

Gear transmission: gear transmission is relying on the active gear to dial the slave gear to realize, one of the basic requirements is its instantaneous angular velocity ratio must remain constant. Classification of gear transmission: gear transmission type is more, according to the two gear transmission relative motion for plane motion or space motion, can be divided into plane gear transmission and space gear transmission two categories. The initial contact of the teeth of straight-toothed cylindrical gears is a line that extends across the entire tooth surface. The initial contact of helical gear teeth is a point which becomes a line as the teeth move into more mesh. In straight toothed cylindrical gears, the contact is parallel to the axis of rotation. In helical gears, the line is diagonal across the face of the teeth. It is the gradual meshing of the gears and the smooth transfer of motion from one tooth to another that gives helical gears the ability to transfer motion smoothly at high speeds and heavy loads. Helical gears allow the bearings of the shaft to withstand radial and axial forces. When the axial force becomes large or has some effect due to other reasons, then the herringbone gear can be made. Double helical gears (herringbone gears) are equivalent to two helical gears mounted side by side on the same shaft in the opposite direction. They produce opposite axial thrust effects, thus eliminating axial thrust. When two or more unidirectional helical gears are on the same shaft, the tooth orientation of the gears should be selected so that axial thrust is minimized.

Worm gear transmission: worm gear transmission is used to transmit the space perpendicular to each other without intersecting the two shafts between the motion and power. The turbine is similar to a staggered shaft helical gear. Pinions, or worm gears, have a smaller number of teeth, usually one to four, and because they are completely wrapped around the pitch cylinder, they are called threaded teeth. The gears that mate with them are called turbines, which are not true gears. Worms and turbines are typically used to provide large angular velocity reduction ratios to drives between vertically intersecting shafts. Turbines are not helical gears, so the top surfaces of their teeth are concave to match the curvature of the worm gears, in order to form a first contact rather than a point contact. However, there is a disadvantage in worm-turbine drive mechanisms of having a large slip rate between teeth, just as there is in staggered-axis helical gears.

BELT DRIVE: Belt drive transmits motion and power through an intermediate flexure (belt). Belt drive is mainly used for two parallel shafts and the same direction of rotation, this drive is called open drive.

Chain drive: chain drive is mounted on the parallel shaft of the master and slave sprocket and the ring chain around the sprocket is composed of the chain as the intermediate flexure, rely on the chain and sprocket gear teeth of the meshing to transfer motion and power. Compared with belt transmission, chain transmission has the following main features: no elastic sliding and slipping, accurate transmission ratio can be maintained; less tension force is needed, and the pressure acting on the shaft is also smaller; compact structure; and it can work in the poor environmental conditions, such as high temperature and oil contamination. Chain drive and gear transmission, compared with its main features: lower manufacturing and installation accuracy requirements; center distance is larger, its transmission structure is simple; instantaneous chain speed and instantaneous transmission ratio is not a constant, transmission smoothness is poor.
