Worm gears are commonly made of cast tin bronze and aluminum iron bronze; Low speed and unimportant transmissions can use cast iron materials. Cast iron bronze: good friction, good adhesion resistance, expensive price, slightly lower strength. Cast aluminum iron bronze: slightly inferior in friction reduction and adhesion resistance, but high in strength and affordable. Cast iron: gray; Ball ink. To undergo aging treatment and prevent deformation.
In practice, worm gears are usually used in conjunction with worm gears. Worm gear and worm gear mechanisms are commonly used to transmit motion and power between two staggered shafts. The worm gear and worm gear are equivalent to gears and racks in their middle plane, and the worm gear is similar in shape to a screw. Worm gears and worm mechanisms are often used in situations where two shafts are interlocked, the transmission ratio is high, the transmission power is not high, or intermittent work is required.
1. It can achieve a large transmission ratio and is more compact than the helical gear mechanism with staggered shafts
2. The meshing tooth surfaces of the two wheels are in line contact, and their load-bearing capacity is much higher than that of the helical gear mechanism with staggered shafts
3. Worm drive is equivalent to spiral drive, which is a multi tooth meshing transmission, so the transmission is smooth and the noise is very low
4. Has self-locking properties. When the lead angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking and can achieve reverse self-locking.
5. Low transmission efficiency and severe wear.
6. The axial force of the worm is relatively large.
