Description

Technical Field

[0001] The utility model relates to the technical field of gear transmission, in particular to a chain latch device. Background Art

[0002] Gear transmission is a common mechanical transmission method, which uses the meshing relationship between gears to transmit power and motion. Gear transmission usually consists of two or more gears, which are installed on shafts respectively, and transmit torque and speed through the meshing between gears. The advantages of gear transmission are high efficiency, precision and reliability, and it often works with gears and toothed belts.

[0003] When the current gear belt is working, the motor usually drives the rotating shaft to start rotating, and then the rotating shaft drives the gear fixed to it to start rotating. The rotation of the gear drives the toothed belt to transmit, and then another gear starts to rotate, realizing the transmission effect. When it is necessary to stop working, the motor is turned off and the transmission work stops.

[0004] In the current existing technology, when it is necessary to temporarily stop working, it is done by turning off the motor. In order to facilitate the direct start of work later, the motor is usually not powered off. This method can normally stop the machine from working. However, since the motor is not powered off, only the motor is turned off. In this way, the motor is stopped by the motor brake. When the motor brake fails, the machine may not be able to stop working completely, resulting in the inability to ensure the safety of work.

[0005] Here we provide a chain latch device. Utility Model Content
