Bronze Alloy Worm Gear Wheel Set Transmission Spare Parts
1) Structural Features
1. Worm Part
The worm resembles a screw in shape and is a helical - shaped shaft. Its lead angle (the angle between the helical line and the axis of the worm)
is a key factor affecting the transmission efficiency and self - locking performance. Generally, the smaller the lead angle,
the lower the transmission efficiency, but the better the self - locking performance.
2. Worm Gear Part
The worm gear is a cylindrical gear with a curved tooth surface. It meshes with the worm, and the worm gear usually has a relatively large number of teeth.
The material of the worm gear is generally bronze and other materials. This is because bronze has good wear - resistance and anti - friction properties.
During the transmission process of the worm - worm gear, there is relative sliding between the worm and the worm gear. The bronze material can reduce
the wear caused by this sliding friction. For example, in some transmission systems with high precision requirements, such as the indexing mechanism of
machine tools, the bronze worm gear can ensure the smoothness and accuracy of transmission.
2) Working Principle
1. Direction of Power Transmission
Usually, the worm is the driving part, and the worm gear is the driven part. When the worm rotates, the helical teeth of the worm
will push the teeth of the worm gear, causing the worm gear to rotate. This transmission method can achieve high - ratio speed reduction.
2. Meshing Process
The meshing of the worm and the worm gear is a combination of sliding and rolling motions. The helical teeth of the worm slide on the tooth surface of
the worm gear, and there is also a component of rolling. This meshing method causes the worm - worm gear transmission to generate a certain amount of
heat while transmitting power. Especially in the case of high - load and high -speed transmission, heat dissipation measures need to be considered.
3) Advantages
a) Large Transmission Ratio: Worm - gear transmission can easily achieve a large transmission ratio.
b) Compact Structure: Compared with some other transmission methods, worm - gear transmission devices can achieve complex power transmission
in a relatively small space.
c) Self - locking Property (in certain cases): When the lead angle of the worm is smaller than the equivalent friction angle of the material,
the worm - gear transmission has a self - locking property.
