A temperature-controlled electromagnetic clutch

Abstract

The invention provides a temperature-control electromagnetic clutch and belongs to the technical field of electromagnetic clutches. The temperature-control electromagnetic clutch comprises a driving part, a driven part, a temperature-control mechanism connected with the driving part, and a cooling mechanism connected with the driven part, wherein the driving part comprises a belt pulley and an electromagnet arranged in the belt pulley; the driven part comprises an armature and a driving shaft arranged at the middle of the armature; the electromagnet comprises an inner coil and an outer coil; the temperature-control mechanism comprises a first temperature-control switch and a second temperature-control switch; the first temperature-control switch is connected with the outer coil; the second temperature-control switch is connected with the inner coil; the cooling mechanism comprises an air cooling device and a cooling pipe; the air cooling device is connected with the driving shaft; the cooling pipe is arranged in the driving shaft and communicates with the air cooling device; the air cooling device comprises a supporting frame, a fan and a cooling disc; the cooling disc is arranged at the end, close to the fan, of the supporting frame; a cooling cavity is formed in the cooling disc; and a plurality of cooling holes which are penetrating from top to bottom are formed in the cooling disc. The temperature-control electromagnetic clutch provided by the invention has the advantages that the temperature-control range is wide, the working temperature stability can be effectively guaranteed, and the service life can be ensured.

Description

technical field [0001] The invention relates to the technical field of electromagnetic clutches, in particular to a temperature-controlled electromagnetic clutch. Background technique [0002] Because some existing equipment will generate heat during work, a cooling device is often provided to control the temperature, so as to ensure the normal operation and service life of the equipment. However, many existing cooling devices are generally started and shut down at the same time as the equipment they serve, and this type of equipment does not need to be in a cooling state all the time, it only needs to avoid its temperature being too high. Solid, this kind of cooling device has the problem of energy waste, in order to solve this problem, some existing cooling devices use electromagnetic clutches and temperature control switches to control the cooling time, such as the Chinese patent No. ZL201420021271.0 discloses a The electromagnetic clutch fan cooling device for engineeri...

Problems solved by technology

Solid, this kind of cooling device has the problem of energy waste, in order to solve this problem, some existing cooling devices use electromagnetic clutches and temperature control switches to control the cooling time, such as the Chinese patent No. ZL201420021271.0 discloses a The electromagnetic clutch fan cooling device for engineering machinery engines, which is connected to the inner and outer coils of the electromagnet through two temperature control switches to achieve timely cooling and cooling intensity

However, this device only achieves cooling by changing the rotating speed of the fan, and its cooling range is limited, which cannot meet the cooling needs of working for a long time in a hot climate
