Analysis and Solutions to Common Malfunctions in Gearboxes
There are many types of reducers, which can be divided into gear reducers, worm reducers, planetary reducers, and their combined reducers according to the transmission type; According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers; According to the shape of the gears, they can be divided into cylindrical gear reducers, bevel gear reducers, and cone cylindrical gear reducers; According to the arrangement of the transmission, it can be divided into expansion type, diversion type, and coaxial type reducers.

Classification and working principle of reducers
Gearboxes are generally used for low-speed and high torque transmission equipment. They reduce the speed of electric motors, internal combustion engines, or other high-speed power by meshing the small gears on the input shaft of the gearbox with the large gears on the output shaft. Ordinary gearboxes also have several pairs of gears with the same principle to achieve the desired reduction effect. The ratio of the number of teeth between the large and small gears is the transmission ratio.

Key points and inspection precautions for gear installation of reducer
Tooth flank clearance: Reasonable tooth flank clearance is crucial for the normal operation of gears. The tooth flank clearance can be measured by pressing a lead wire, a feeler gauge, or a dial gauge. The clearance is too small, and the gears are prone to overheating and jamming during operation; If the gap is too large, it can cause impact and vibration.

The demand for driving humanoid robots is exploding, and domestic substitution is accelerating
Harmonic reducer is the core component of rotary actuator, consisting of flexible wheel, rigid wheel and wave generator. The transmission principle is the staggered motion between flexible wheel and rigid wheel. The core is the elastic deformation of flexible wheel and the staggered motion of gear meshing. The wave generator deforms the flexible wheel, and the external teeth of the flexible wheel mesh with the internal teeth of the rigid wheel to achieve deceleration. Its main function is to reduce the speed and increase the torque.

Daily operation and maintenance of gearbox
During the daily operation and maintenance of the gearbox, a comprehensive inspection plan should be developed based on the actual working condition of the machine, which is beneficial for the normal and stable operation of the equipment. In daily work, staff need to pay full attention to the daily operation of the reducer, and develop a comprehensive maintenance plan based on specific situations, which is conducive to fully realizing the application value of the reducer itself.
