High temperature industrial fan with its widespread use, in many industries it plays a very key role. With the improvement of technology, we can also appropriate the fan to improve the operation, through the improvement, improve performance, how to improve the fan?
- the improvement of the reduction gear, the reduction gear material from 45 steel to 40Cr, high-temperature fans after the mechanical properties and hardness, not only can effectively prevent plastic deformation of the gear teeth, and the gear has sufficient resistance to wear and pitting ability.
- the installation of improvements, in order to make high-temperature fans run smoothly, shall not have periodic impact noise, in the installation or replacement of reduction gear, must ensure that the two gear transmission contact spot along the tooth length of not less than 65%, along the tooth height of not less than 45%.
- manufacturing improvements, in order to make the tooth core material has sufficient toughness, in order to prevent local fracture phenomenon when the gear teeth are overloaded, we require an appropriate increase in the radius of the tooth root transition fillet during manufacturing, to eliminate the processing knife marks there, so as to reduce the stress concentration.
