Features of helical gear transmission

 The meshing condition of the helical gear is that the normal modulus is equal to the normal pressure angle. In the transmission process, the transmission efficiency is low and the wear is fast, so it is often used in instruments and small auxiliary transmissions.

The gear transmission between the staggered shafts composed of two paired helical gears is also called the staggered shaft helical gear transmission.

In the principle of helical gear transmission, the tangent point of the two indexing circles is the common tangent plane of the two indexing cylinders, and the included angle projected by the two wheel shafts on the plane is called the shaft angle [33] When the direction of the helix angle 1.2 of the two wheels is the same, |[33]|=|1|+|2|; when the directions of the two helix angles are opposite, |[33]|=|1|-|2|. The normal moduli of the paired helical gear drives must be equal; if the helix angles are not equal, the end moduli are not equal. As with a spur gear transmission between parallel shafts, the transmission ratio is equal to the inverse ratio of the number of teeth on the two wheels. Due to the high sliding speed between the teeth, the transmission efficiency is low, the wear is fast, the contact stress is large, the bearing capacity is poor, and the service life is short. Therefore, helical gear transmission is only used to transmit motion or small power.

The helical gear transmission is the gear transmission between the crossed shafts composed of two paired helical gears, also known as the crossed shaft helical gear transmission. The meshing condition of the helical gear is that the normal modulus and the normal pressure angle are equal. In the transmission process, the transmission efficiency is low and the wear is fast, so it is often used in instruments and small auxiliary transmissions.
