Technical Field
The utility model relates to a carry the accessory, especially relate to a hold-in range wheel heat radiation structure.
Background
The synchronous belt pulley is a key component for driving the synchronous belt to run, the synchronous belt pulley is mainly connected to a shaft through interference fit of the synchronous belt pulley and a flat key, the flat key needs to bear a large load in the process that the shaft drives the synchronous belt pulley to rotate, the calorific value is large, meanwhile, the synchronous belt pulley needs to continuously rub the synchronous belt in the process of driving the synchronous belt to run, the heat generated by the synchronous belt pulley is also large, and the two parts of heat are easily subjected to thermal deformation if being excessively concentrated, so that the phenomena of loose connection, deviation of the synchronous belt and the like can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the synchronous pulley heat radiation structure with the good heat radiation effect is provided.
In order to solve the technical problem, the utility model discloses a technical scheme is: a synchronous pulley heat dissipation structure comprising: a synchronous belt wheel, a rotating shaft and a frame, wherein a flat key groove is arranged in the synchronous belt wheel, a flat key matched with the flat key groove is arranged on the rotating shaft, the synchronous belt pulley is sleeved on the rotating shaft through interference fit, the flat key is embedded in the flat key groove through interference fit, the end part of the rotating shaft is rotatably arranged on the frame through a bearing seat, a limiting disc is arranged at one end of the synchronous belt wheel far away from the bearing seat, a heat radiating blade is arranged on a rotating shaft between the synchronous belt wheel and the bearing seat, the outer side of the radiating blade is provided with a sleeve which is fixedly arranged on the rotating shaft through a supporting frame, a conical flow guide sleeve is arranged at one end of the sleeve close to the bearing seat, a first heat dissipation hole is arranged in the flat key in a penetrating way, and a second heat dissipation hole communicated with the first heat dissipation hole is formed in the limiting disc in a penetrating mode, and a plurality of third heat dissipation holes are uniformly formed in the synchronous belt wheel in a penetrating mode along the radial direction.
In order to better solve the technical problem, the utility model discloses a further technical scheme is: a filter screen is arranged between one end of the sleeve close to the conical flow guide sleeve and the rotating shaft.
The utility model has the advantages that: above-mentioned hold-in range wheel heat radiation structure, it rotates to utilize the pivot to drive the impeller, the impeller forms the heat dissipation air current with the outside air and carries out the forced air cooling heat dissipation to parallel key and synchronous pulley, the louvre that the air current can continuously pass on parallel key and the synchronous pulley constantly takes away the heat, the radiating effect is good, simultaneously, adopt toper water conservancy diversion cover and sleeve can carry out the water conservancy diversion to the outside air current, can form stronger heat dissipation air current, in addition, utilize the sleeve to protect radiating vane, prevent to expose the emergence incident.
