Product Details
Structure of Worm Gear and Worm drive
The structural forms of worm gears are divided into three types: one is an integral structure, such as cast iron or bronze worm gears with small diameters.
The second scenario is the gear ring press fit type, with the wheel hub made of cast iron or cast steel and the rim made of bronze.
The three types of wheel rims and wheels are connected with twisted holes and bolts, which is convenient for disassembly and assembly.
Features of Worm drive: 1. Compact structure and large transmission ratio. We usually use Z1 to represent the number of heads of a worm, and the typical number of heads is 1-4. We usually use Z2 to represent the number of worm teeth. The reduction ratio in Worm drive is: I=Z2/Z1. When the worm Z1=1, it is a single head. When the worm rotates one circle, the worm wheel rotates one tooth, so a large transmission ratio can be obtained. Generally, in power transmission, the transmission ratio is I=10-80. In indexing mechanism, I can reach 1000. For such a large transmission, such as gear transmission, multi-stage transmission should be adopted, so Worm drive is compact, small in size, and light in weight.
