Embodiment Construction
[0026] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0027] Such as figure 1 Shown: In order to be able to effectively control the slipping phenomenon of the pneumatic clutch, that is, to protect the pneumatic clutch when there is a speed difference between the driving wheel and the driven wheel of the pneumatic clutch, or when the air source pressure is under pressure, to avoid the pneumatic clutch damage, the present invention includes a master speed sensor for detecting the speed of the clutch driving wheel, a slave speed sensor for detecting the speed of the clutch driven wheel, and an air pressure sensor for detecting the corresponding pressure value of the air source pressure; the master speed sensor passes through the first A signal conditioning circuit is connected to the first counter circuit, the speed sensor is connected to the second counter circuit through the second signal conditioning circuit, and ...

The invention relates to a pneumatic clutch anti-slip protective system. The pneumatic clutch anti-slip protective system comprises a main rotating speed sensor, an auxiliary driven rotating speed sensor used for detecting the rotating speed of a driven wheel of a clutch, and a pressure sensor used for detecting pressure values corresponding to air source pressure. The main rotating speed sensor is connected with a first counter circuit through a first signal processing circuit, the auxiliary rotating speed sensor is connected with a second counter circuit through a second signal processing circuit, and the pressure sensor is connected with a logical or control circuit through a third signal processing circuit. An output end of the first counter circuit is connected with the second counter circuit and a logic comparison circuit, the second counter circuit is connected with the logic comparison circuit through a rotating difference gear selecting circuit, an output end of the logic comparison circuit is connected with the logical or control circuit, and the logic or control circuit is connected with a switch circuit. The pneumatic clutch anti-slip protective system is compact in structure, can effectively protect a pneumatic clutch, prolongs service life of the pneumatic clutch, and is safe and reliable.
Description
technical field [0001] The invention relates to a control system, in particular to a pneumatic clutch anti-slip protection system, which belongs to the technical field of clutch control. Background technique [0002] Clutch is a common mechanism in machinery. Its function is mainly to control the output of mechanical power through the clutching and closing of the friction plate. Usually, it can be divided into manual lever type and hydraulic type according to the form of axial force acting on the friction plate. with pneumatic. The pneumatic clutch is to use the fluid to pass through the steam and use the compressed air as the power to realize the axial engagement and separation of the friction plates. [0003] When the pneumatic clutch is used under overload, it will slip. At this time, the friction part of the clutch will be heated and damaged, resulting in the paralysis of the entire transmission system. Contents of the invention [0004] The purpose of the present in...
