The invention discloses a grating-free non-contact explosion-proof rotating signal transmission device, and relates to an explosion-proof rotating signal transmission device. The device solves the problem that an anti-explosion rotating signal transmission device of an existing anti-explosion product is high in cost due to the fact that the requirements for performance of integrated circuits, semiconductor components and the like in the rotating signal transmission device are extremely high. A motor shaft is arranged on a flange shell in a penetrating manner. A magnetic ring is sleeved on themotor shaft on the inner side of the flange shell. An integrated receiver is arranged on the inner side wall of the flange shell right above the motor shaft. An outer cover of the rotary signal transmission device is mounted on the flange shell through an outer cover mounting bolt and an O-shaped sealing ring. The joint of the rotating signal transmission device outer cover and the flange shell isan explosion-proof joint face, the explosion-proof lead sleeve is installed on the flange shell and the rotating signal transmission device outer cover through explosion-proof threads, and the sealing gasket is installed on the outer side face of the flange shell. The device is used for flame-proof rotation signal transmission.
Description
technical field [0001] The invention relates to a flameproof rotary signal transmission device, in particular to a grating-free non-contact flameproof rotary signal transmission device. Background technique [0002] The rotary signal transmission device is a device that compiles and converts signals or data into signal forms that can be used for communication transmission and storage. Applied to the motor, it can be used to detect whether the motor is running according to the direction and speed designed by the system, and it plays a role of monitoring and protection. The working principle of the traditional rotary signal transmission device: it consists of a photoelectric code disc with a shaft in the center. figure 1 . [0003] At present, the rotary signal transmission devices on the market are roughly divided into two types in terms of installation methods, one is the small shaft type, and the other is the shaft sleeve type. No matter what kind of rotary signal transm...
