[0002] With the progress of the times, science and technology are constantly developing. As an important part of the mechanical transmission system, the gear reducer can meet the needs of various industrial applications by changing the speed and torque. However, the gear reducer itself does not generate power, but is used to transmit power between the prime mover and the working machine. Therefore, the emergence of a gear reducer with air cooling and buffer structure is particularly important.

[0003] To this end, the patent with publication number CN215293534U discloses a gear reducer, wherein a heat dissipation fan is fixedly installed on the top of the gear reducer housing, an output shaft is penetrated through the rear end of the gear reducer housing, a heat dissipation fin is fixedly installed on the right side of the gear reducer housing, and an observation window is fixedly installed on the left side of the gear reducer housing. This gear reducer is protected by the gear reducer housing and the motor housing, and the heat dissipation fan, heat dissipation fins and circular holes arranged on the surface can dissipate heat well, thereby ensuring the normal operation of the gear reducer. The vibration generated by the gear reducer can be effectively buffered by multiple buffer springs to ensure its stability. According to the on-site conditions, the whole can be raised and lowered by an electric telescopic rod to adapt to different on-site conditions. The sound insulation board and sound-absorbing cotton inside the housing can effectively reduce noise, improve the working environment, and avoid noise pollution.

In addition, sound insulation is done inside the setting, which has good sound insulation effect and is very environmentally friendly. However, due to its insufficient dust prevention, the motor is easily dusty and inconvenient to clean, making the convenience of the gear reducer low. Utility Model Content
