Mechanical transmission is widely used in mechanical engineering, mainly refers to the transmission of power and movement by mechanical means.
Divided into two categories: one is the transmission of power and friction transmission by friction between the parts, including belt transmission, rope transmission and friction wheel transmission.Friction transmission is easy to achieve stepless speed change, and can be adapted to transmission occasions with large shaft spacing. Overload and slippage can also play a role in buffering and protecting the transmission device, but this type of transmission generally cannot be used in high-power applications and cannot guarantee accuracy. The transmission ratio.
The second is the meshing transmission that relies on the meshing of the driving part and the driven part or the transmission of power or movement with the help of intermediate parts, including gear transmission, chain transmission, spiral transmission and harmonic transmission.The meshing transmission can be used in high-power applications, and the transmission ratio is accurate, but generally requires higher manufacturing accuracy and installation accuracy.
The mechanical transmission mechanism can change the mode, direction or speed of the movement provided by the power, and it can be used purposefully by people.There are many types of transmission mechanisms in ancient China, and they are widely used. In addition to the above introduction, seismometers, blowers, etc., are all products of mechanical transmission mechanisms.Transmission mechanisms in ancient China mainly include gear transmission, rope-belt transmission and chain transmission.
