Technical Field
[0001] The utility model relates to the technical field of rotary drive, in particular to a rotary drive inlaid with cast iron gear ring. Background Art
[0002] The rotary drive uses a worm gear transmission to achieve a reduction drive. The worm gear transmission has a self-locking function. The worm wheel is generally manufactured as an integral part. For example, a rotary drive transmission device disclosed in Chinese patent literature (patent number: CN201920251268.0) has a worm wheel that is manufactured as a whole. In general, steel gears are used in the manufacture of worm wheels. After the worm wheel is worn out after long-term use of the rotary drive, the entire rotary drive needs to be replaced. The early rotary drive has a high cost and low economic benefits. Replacing the entire rotary drive will also cause material waste. To solve the above problems, we use the teeth on the surface of the outer gear ring for inlaying.
