WPWDKT Series Universal Speed Worm Gearboxes
The main components of the worm reducer(WPWDKT Series Worm Gearboxes) are worm gear, worm, bearing, casing, etc., and others include oil seals, caps, bolts, etc. The worm gear is generally made of tin bronze, and the paired worm material is hardened to HRC4555 with 45 steel or 40Cr hardened to HRC5055 and then ground to a roughness of Ra0.8μm by a worm grinder. Worm reducers are widely used in the chemical industry, printing, packaging, lifting, food, and other fields.

Specifications Parameter
Structural Features of Worm Gear Reducer:
A large transmission ratio can be obtained, which is more compact than the staggered-axis helical gear mechanism.
The meshing tooth surfaces of the two wheels are in line contact. And their bearing capacity is much higher than that of the staggered shaft helical gear mechanism.
The worm drive is equivalent to a screw drive, a multi-tooth meshing drive, so the industry is stable, the noise is slight, and it is self-locking.
When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking; that is, only the worm can drive the worm, but not the worm. Such as the self-locking worm mechanism used in its heavy machine, its reverse self-locking can play a role in safety protection.
The transmission efficiency is low, and the wear is severe. When the worm gear is engaged in the transmission, the relative sliding speed between the meshing gear teeth is significant, so the friction loss is substantial, and the efficiency is low. On the other hand, the relative sliding speed causes severe wear and heat generation on the tooth surface. More expensive materials with good anti-friction and anti-wear properties and suitable lubricating devices are often used to dissipate heat and reduce wear, so the cost is high. , the axial force of the worm is large.
