摘要
To increase the torque transmission capacity of a gear wheel, it is necessary to control the contact pressure on the tooth face. By increasing the elasticity of the gear tooth, it deforms more easily when a load is applied. This increases the contact area between the teeth, thus reducing the specific contact pressure. By producing a gear tooth with a hollow core (3) along the tooth axis, its deformability is increased. Lubrication oil, pumped via a central shaft hole and a cross hole reaches the core hole from where it is forced to the tooth contact surface through a hole normal to the pressure face.
