Its traces can be seen in various mechanical transmission systems, and the hard tooth surface gear reducer has played a significant role in common household appliances, clocks, and so on in daily life The application of reducers can be seen from the transmission of large power to the transmission of small loads from various angles. Let's take a look at the basic structure of a hard tooth surface gear reducer together.

The casing of a hard tooth surface gear reducer consists of two parts: the box seat and the box cover, and its dividing surface passes through the transmission axis. The holes for installing bearings on the casing should be drilled very accurately to ensure the correct position of the gear axis. In order to facilitate the removal of the cover, two threaded holes are drilled on the flange of the box cover in some areas, so that the cover can be lifted when the cover screw is screwed in. In order to increase the rigidity and heat dissipation area of the gearbox, external ribs are added to the casing.

There is a sight hole on the box cover for checking the engagement and injecting oil into the box, and the sight hole is usually covered with a sight hole cover. When the hard tooth surface gear reducer is working, the temperature rises, which will cause the air inside the box to expand, and the oil will be released from the respective split surfaces. Therefore, a ventilation cap is installed on the box cover to allow air to escape freely. There is an oil drain hole on the upper part of the box seat, which is used for draining oil. It is usually sealed and tightened with an oil plug.
