The correct meshing conditions for helical gears are that the normal modulus of two helical gears is equal, the normal pressure angle of two helical gears is equal, and the helix angle of two helical gears is equal in size and opposite in direction. These conditions are the foundation for the normal operation of helical gears.As a special type of...

What are the lubrication methods for gear reducersGear reducer is a mechanical device that uses various levels of gear transmission to achieve the purpose of speed reduction. If the friction and wear of the gears in the gear reducer are not lubricated, it is easy to cause damage to the mechanical equipment. Therefore, lubrication of the reducer is ...

The calculation of gear transmission ratio is based on the tooth ratio of the gear. The transmission ratio (i) is defined as the ratio of the number of teeth (z1) of the driving gear (usually connected to the motor) to the number of teeth (z2) of the driven gear (usually connected to the load), expressed by the formula:\[i=\ frac {z1z2} \]This me...
