Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reducers, in particular to a reducer with a high-precision anti-reversal structure. Background Art
[0002] A reducer is a mechanical transmission device that reduces the speed of the input shaft through the rotation of gears or other transmission elements, while increasing the torque to meet the different power transmission requirements of various mechanical equipment. In modern industrial production, reducers are widely used. Whether it is automated equipment on production lines or large machinery on construction sites, reducers are indispensable. The design and manufacture of reducers involve multiple technical fields, including mechanical design, materials science, thermodynamics and electronic control. Technological innovations and patent protection in these fields are also important driving forces for the development of the reducer industry.
[0003] After the existing reducer is completed, it may reverse unexpectedly. The reversal will cause the working direction of the reducer to be inconsistent with the expectation, affecting the normal operation of the equipment, reducing the working efficiency and output effect. The reversal may also cause the gears and other transmission components in the reducer to bear uneven loads, accelerate the wear and damage of parts, and shorten the service life of the equipment. In addition, the reversal also means that the reducer needs additional energy to overcome the reverse torque, which will lead to energy waste and increase operating costs. Utility Model Content

Under the limiting effect of the locking rod 409, the reducer rotating rod 2 will not rotate, ensuring that the reducer rotating rod 2 will not reverse, thereby ensuring the stability and safety of the reducer; in summary, the mechanical locking mechanism 4 uses a mechanical snap-in method to fix and limit the rotating rod in the reducer, thereby avoiding reversal of the reducer rotating rod and the inner teeth. The electric drive method of the mechanical locking mechanism 4 ensures that the snap-in operation is stable, guarantees the stability and reliability of the snap-in, and avoids reversal of the rotating rod.
