Research on Steel Worm Gear Transmission
Yao Yuquan
In copper worm gear transmission,lower bearing capacity and shorter service life are pointed out,and one of the effective ways to solve the problems is to use steel worm gear instead of copper worm gear and with suitable lubricants and additives.The experiments proved that the efficiency of the proposed transmission had reached to 85% and the bearing capacity to 214% rated torque of copper gears.The specific wearability is too slow to be measured.Thus,the outline size of copper reduction gears can be reduced largely.
