Hard toothed reducer refers to a reducer where the hardness of the internal gears is greater than 350HBS, and the large and small gears have undergone quenching or carburizing treatment. It is usually used in situations where the transmission size is restricted by structural conditions and in the transmission devices of transportation machinery. The bearing capacity of hard toothed gears is relatively high. It is processed by quenching or carburizing after the gears are finely cut to increase the hardness. However, during the heat treatment process, gears inevitably undergo deformation, so after the heat treatment, grinding, polishing or fine cutting must be carried out to eliminate the errors caused by the deformation and improve the accuracy of the gears. 

So what are its advantages?? Let's take a look at the introduction from the hard toothed reducer manufacturer.

Its advantages lie in the design of the gears, which takes into account both the pressure on the gear tooth surface and the strength of the tooth root. This significantly enhances the hardness and precision of the gears, which can greatly reduce the weight of the reducer, making it smaller in size. Additionally, the performance of the reducer has been greatly improved, with the transmission efficiency increasing by one level. On the other hand, it also significantly reduces the cost of maintenance and repair for users.
