Description

Gearbox for stereo garage

Technical Field

The invention relates to the technical field of gearboxes, in particular to a gearbox for a stereo garage.

Background

The speed changer consists of a speed change transmission mechanism and an operating mechanism, and a power output device can be additionally arranged when required. There are two ways in classification: the gear ratio variation mode and the operation mode are divided into different modes.

However, the existing gearbox still has the following defects in practical use:

firstly, the reliability is poor, the temperature fluctuation in the gearbox is large, and the high or low temperature is not beneficial to the normal operation of the gearbox;

secondly, the safety is poor, because the friction between the transmission shafts inside the transmission case can generate metal debris in the working process of the transmission case, the metal debris in oil in the transmission case can be adsorbed by arranging a magnet inside a lower end cover in the traditional mode, but the magnetism of the traditional magnet disappears faster, and meanwhile, the metal debris adsorbed on a bottom plate is dispersed, so that the metal debris is easily brought back to the oil to move under the movement of the oil, and the abrasion of the transmission shafts is increased;

thirdly, the sealing performance is poor because it prevents oil leakage only by providing a gasket, but this is poor and the user cannot know immediately when oil leakage occurs in the transmission.

The working principle is as follows:

the working principle of the temperature control assembly is as follows:

firstly, the processing module 21 monitors the temperature inside the box body 2 in real time through the temperature sensor 13;

secondly, when the processing module 21 detects that the temperature inside the box body 2 is too high, the processing module 21 instructs the semiconductor refrigerating device 12 to work, and instructs the second electromagnet 36 at the cold end of the semiconductor refrigerating device 12 to be electrified (at the moment, the second electromagnet 36 at the hot end of the semiconductor refrigerating device 12 is not electrified), so that the heat conducting rod 33 is in contact with the semiconductor refrigerating device, the cold energy is conducted to the heat conducting plate 14, and finally the heat conducting plate 14 cools the box body 2 until the temperature inside the box body 2 returns to normal;
