Disclosure of Invention
The purpose of the invention is as follows: the utility model discloses an solve present belt pulley and only can play driven effect, driven in-process equipment and transmission position can produce a large amount of heats, influence the life-span at transmission position, furtherly, also influences the problem in the life-span of equipment.
The technical scheme is as follows: the utility model provides a following technical scheme:
the utility model provides a can form belt pulley of directional air current, includes the belt pulley body, has the air current dish in the arbitrary one side of belt pulley body, the air current dish is circular disc, and the outer diameter of inner ring and belt pulley is the same to set up in the outside of belt pulley, be equipped with a plurality of evenly distributed's air current groove on the circumference quotation of air current dish around the belt pulley, the air current groove runs through the quotation of air current dish.
This is the first embodiment, do not adjust the direction of fan leaf between the air current groove, the air current groove disc face really can not be called the fan leaf in fact this moment yet, because the quotation does not have the function of air supply yet, it is one reason that the inbound passenger of concrete realization principle and high-speed railway can not stand in the edge, after the belt pulley is driven, the air current groove of belt pulley drives the air current and forms high-speed air current in air current dish department, make the air on every side can automatic replenishment go into here, and it is corresponding, also have partial high-speed air current in belt pulley department, so the direction of air current can form, the air current dish is outer to the air current dish, the outer flow direction to the belt pulley of air current dish, make the air current can form the measure of cooling to air current dish and equipment.
Furthermore, the positions of the plate surfaces of the airflow plates uniformly distributed with the airflow grooves correspond to the radiating surfaces of the equipment provided with the belt pulley body.
Furthermore, a plurality of fan blades are formed among the airflow grooves, and the fan blades have an inclination angle towards the belt pulley body.
Owing to there has the angle of inclination, the quotation between the air current groove can become the fan leaf, has the function of fanning, after the air current dish rotates fast, can form the cooling measure of the air supply of orientation equipment or the follow equipment department convulsions, no matter what kind of incline direction of adoption, is the air supply when equipment department, and that sets up the quotation in the one side that the equipment was kept away from to the belt pulley, and the belt pulley also can be cooled by the air supply, sets up in the one side that the equipment is close to the belt pulley when the quotation, and the belt pulley just.
Further, the center of gravity of belt pulley has the shaft hole, and the shaft hole has a draw-in groove for it can rotate under the drive of belt pulley with the shaft hole cooperation back to have bellied pivot.
Further, the airflow plate and the belt pulley are integrally molded.
Has the advantages that: compared with the prior art:
adopt the design scheme of the utility model, under the condition that does not increase new drive apparatus, improved the utilization ratio to the energy, can cool down belt pulley and equipment simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;
fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
Detailed Description
The present invention is further illustrated by the following figures and specific examples, which are to be understood as illustrative only and not as limiting the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalent modifications thereof which may occur to those skilled in the art upon reading the present specification.
Example 1
The utility model provides a can form belt pulley of directional air current, includes belt pulley body 1, has airflow disk 2 in the arbitrary one side of belt pulley body 1, airflow disk 2 is circular disc, and the inner ring is the same with the external diameter of belt pulley 1 to set up in the outside of belt pulley, be equipped with a plurality of evenly distributed's air current groove 3 on airflow disk 2 around the circumference quotation of belt pulley, air current groove 3 runs through airflow disk 2's quotation.
This is the first embodiment, and does not adjust the direction of the fan blade between the air current groove, and at this moment, the disc surface between the air current grooves can not be called as the fan blade in fact either, because the disc surface does not have the function of supplying air yet, the concrete realization principle and the reason that the high-speed rail enters the passenger and can not stand on one side are not realized.
When the belt pulley 1 is driven, the airflow groove 3 of the belt pulley 1 drives the airflow to form high-speed airflow at the airflow disc 2, so that the surrounding air can be automatically supplemented into the airflow groove, and correspondingly, a part of high-speed airflow also exists at the belt pulley 1, so that the direction of the airflow can be formed, the airflow disc 2 extends to the airflow disc 2, and the airflow disc 2 extends to the flow direction of the belt pulley 1, so that the airflow can form a cooling measure for the airflow disc 2 and equipment.
The positions of the plate surfaces of the airflow plates 2, on which the airflow grooves 3 are uniformly distributed, correspond to the heat radiating surface of the equipment provided with the belt pulley 1 body.
The centre of gravity of belt pulley 1 has shaft hole 4, and shaft hole 4 has a draw-in groove 5 for it can rotate under belt pulley 1's drive with shaft hole 4 cooperation back to have bellied pivot.
