Planetary Double Enveloping 90 Degree Worm Gearbox

Product Description

In a Planar double enveloping 90 degree gearbox,three to eleven gear teeth are typically in contact with the worm, depending upon the ratio. The increased number of driven gear teeth that are in contact with the worm significantly increases torque capacity, also raises shock load resistance. In addition to increasing the number of driven gear teeth in contact with the worm, Planar double enveloping 90 degree gearboxalso increases the contact area on each gear tooth. The actual areas of instantaneous contact between the worm threads and the driven gear tooth are lines. These lines of contact move across the face of the gear tooth as it progresses through its total time of mesh with the worm. The lines of contact in double-enveloping worm gearing are configured to increase the power transmission capability and reduce the stress on each gear tooth.

Working conditions:

Twoshafts for 90 ° Intersect, input speed must not be more than 1500 rpm.The working environment temperatureshould ranges from 0 ~ 40 ° C, when the environment temperature below 0 ° C or above 40 ° C.Before starting the lubricating oil to corresponding heating and cooling, The worm shafts, reverse operation can be positive.


The advantageof Planar double enveloping 90 degree gearboxdesign are dramatic. First, the total load is divided among more individual gear teeth, and the load is further divided where teeth support two lines of contact. This superior load distribution greatly increases load carrying capacity. Second, the improved torque throughput allows a smaller reducer to produce the same amount of torque, resulting in size and weight savings.
Double-enveloping worm gearing can carry loads that would require much larger and heavier cylindrical worm gearing.
