Technical Field

[0001] The utility model relates to the technical field of non-standard automation, in particular to an outer shell airtight leakage detection device. Background Art

[0002] The transmission, also known as the gearbox, is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or divided manner. The transmission consists of a speed transmission mechanism and an operating mechanism. Some cars also have a power output mechanism. Most transmission mechanisms use ordinary gear transmissions, and some use planetary gear transmissions. Ordinary gear transmission speed change mechanisms generally use sliding gears and synchronizers.
