Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical components and relates to a pulley, in particular to a high heat dissipation pulley. Background Art

[0002] A pulley is a mechanical device that transmits power through a belt. It is widely used in various industrial equipment and mechanical transmission systems. The design of the inner ring of the pulley has an important influence on the transmission efficiency and performance of the pulley.

[0003] The inner ring of the pulley is usually composed of a series of grooves or teeth, which are used to accommodate and fix the belt. The design of the inner ring needs to ensure that the belt can be firmly attached to it and provide stable power transmission during operation. The pulley is prone to heat up due to long-term friction between the pulley and the belt. Long-term contact between the belt and the heated pulley can easily lead to unexpected situations such as thermal fatigue and breakage of the belt. Summary of the invention

[0004] The utility model aims to solve the above problems existing in the prior art and provides a high heat dissipation pulley which can prevent foreign matter from entering and automatically adjust the heat dissipation.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a high heat dissipation pulley, characterized in that it includes an integrally formed inner ring body, a heat dissipation end is provided on one side of the inner ring body, a plurality of annular heat dissipation grooves are opened on the heat dissipation end, a plurality of heat dissipation grooves are provided on each of the plurality of heat dissipation grooves, and a rotatable groove cover is provided on the mounting seat, a limiting boss is provided on the top of the mounting seat, and a reset torsion spring is provided between the limiting boss and the groove cover.

[0006] In the above-mentioned high heat dissipation pulley, a transfer ring coaxially arranged with the mounting seat is provided on the through-slot cover plate, and a positioning column is provided on the transfer ring.

[0007] In the above-mentioned high heat dissipation pulley, the top of the through-slot cover plate is provided with an inclined drainage chamfer, and the side walls of the through-slot cover plate are provided with anti-collision fillets.

[0008] In the above-mentioned high heat dissipation pulley, one side of the inner ring body is a positioning end, and the positioning end is provided with a plurality of positioning holes.

[0009] Compared with the prior art, the high heat dissipation pulley of the present invention closes the heat dissipation slot through the slot cover to reduce the entry of foreign matter, and has a torsion spring to control the opening range of the slot cover to adjust the heat dissipation effect. The drainage chamfer on the top of the slot cover disrupts the air to make the air flow further increase the heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , 2 As shown in Figures 3, 4 and 5, the high heat dissipation pulley comprises an integrally formed inner ring body 4, a heat dissipation end 12 is provided on one side of the inner ring body 4, a plurality of annular heat dissipation grooves 3 are formed on the heat dissipation end 12, a plurality of heat dissipation grooves 3 are uniformly distributed, a mounting seat 10 is provided on each of the plurality of heat dissipation grooves 3, and a rotatable groove cover plate 2 is provided on the mounting seat 10, a limiting boss 11 is provided on the top of the mounting seat 10, and a reset torsion spring 1 is provided between the limiting boss 11 and the groove cover plate 2. When the inner ring body 4 rotates, the groove cover plate 2 rotates toward the outer ring due to the centrifugal force and opens the heat dissipation grooves 3. The speed adjustment changes the opening amplitude of the heat dissipation grooves 3 to increase the heat dissipation efficiency.

[0018] Preferably, a rotation ring 9 coaxially arranged with the mounting seat 10 is provided on the through slot cover plate 2, and a positioning column 6 is provided on the rotation ring 9. The reset torsion spring 1 closes the through slot when the inner ring body 4 is stationary to reduce the entry of foreign matter, and the channel positioning column 6 limits the heat dissipation through slot 3 to prevent the reverse opening.

[0019] Preferably, an inclined drainage chamfer 7 is provided on the top of the through-groove cover plate 2, and anti-collision fillets 8 are provided on the side walls of the through-groove cover plate 2. The angle formed by the drainage chamfer 7 disturbs the air when the inner ring body 4 rotates, thereby increasing the heat dissipation efficiency.

[0020] Preferably, one side of the inner ring body 4 is a positioning end 13 , and the positioning end 13 is provided with a plurality of positioning holes 5 .

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although this article uses more terms such as torsion spring 1, slot cover plate 2, heat dissipation slot 3, inner ring body 4, positioning hole 5, positioning column 6, drainage chamfer 7, anti-collision fillet 8, transfer ring 9, mounting seat 10, limiting boss 11, heat dissipation end 12, positioning end 13, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
