21 Inch Enclosed Worm Gear Slew Drive , Small Slew Drive For Automation Robotics

Description

Worm gear mechanism characteristics

1. Can get a large transmission ratio, more compact than staggered axle oblique gear mechanism

2. Two wheel meshing tooth surface for line contact, its bearing capacity is much higher than the staggered axle oblique gear mechanism

3. Worm drive is equivalent to spiral transmission; it is multi-tooth meshing transmission, so the transmission is smooth, low noise

4. Self-locking. When the guide angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has feature of self-locking; it can realize the reverse self-locking, that is to say, only the worm to drive the worm wheel. With this feature, the worm mechanism used in heavy machinery can play a safety protection role.

5. Low transmission efficiency, serious wear. When the worm gear is engaged in transmission, the relative sliding speed between the meshing teeth is large, so the friction loss is large and the efficiency is low. On the other hand, relative sliding speed ambassador tooth surface wear is serious and over heat, in order to dissipate heat and reduce wear, often the use of more expensive anti-friction and abrasion resistance of better materials and good lubrication device, so the cost is higher

6. Large worm axial force
