Description
본 발명은 동력 전달 기능을 향상시킨 V-벨트에 관한 것이다.The present invention relates to a V-belt with improved power transfer function.
자동차용 V-벨트는 사용 속도가 높고 부하가 크며 풀리 직경이 작을 뿐 아니라 만곡율도 높은 상태에서 사용되므로 동력전달 효율과 내구성을 높이기 위하여 두께를 얇게 만들어 V홈을 파놓은 V리브드 벨트가 많이 사용되고 있다.V-belts for automobiles are used in high speed, high load, low pulley diameter, and high curvature, so V-ribbed belts with V-grooves are used in order to increase power transmission efficiency and durability. have.
그러나 도 2에 도시하는 것과 같이 V-벨트(10)는 풀리(11) 그루우브 옆면과의 쐐기작용에 의한 마찰력에 의해 동력을 전달하게 되므로 1개의 V-벨트가 전달가능한 동력의 양은 마찰계수(접촉면압)에 의해 제한되므로 큰 동력 전달시에는 미끌림(slip)이 발생되며 많은 벨트를 사용할 수 밖에 없기 때문에 배치설계(Lay out)에 불리한 문제점이 있게 된다.However, as shown in FIG. 2, since the V-belt 10 transmits the power by the frictional force due to the wedge action with the side surface of the pulley 11, the amount of power that can be transmitted by one V- The slip is generated at the time of large power transmission, and a large number of belts can not be used, which is disadvantageous in lay out.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 풀리와의 접촉면압을 증대시켜 동력전달 성능을 향상시킨 V-벨트를 제공하는 데 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a V-belt having improved power transmission performance by increasing a contact surface pressure with a pulley.
상기한 목적을 달성하기 위한 본 발명은According to an aspect of the present invention,
풀리의 그루우브 옆면과의 마찰력에 의해 동력을 전달하는 V-벨트에 있어서,A V-belt for transmitting power by a frictional force with a side surface of a groove of a pulley,
상기 V-벨트 몸체내에는 양측의 마찰 접촉면에 힘을 가해 풀리와의 접촉면압을 높이도록 탄발하는 압축스프링이 내장되어 있는 것임을 특징으로 한다.The V-belt body is provided with a compression spring that elastically biases the friction contact surfaces of both sides to increase the contact surface pressure with the pulley.

이하 본 발명의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 V-벨트의 단면으로서 도면중 부호 1은 V-벨트이며 V-벨트(1)는 풀리(2)의 그루우브(3)내에 끼워져 쐐기 작용에 의한 마찰력으로 동력을 전달한다.1 is a cross-sectional view of a V-belt according to the present invention. In FIG. 1, reference numeral 1 denotes a V-belt, and the V-belt 1 is fitted in a groove 3 of a pulley 2 to transmit power by a wedge- do.
V-벨트(1)의 양측 마찰접촉면(4)(5)은 대략 38°∼40°를 유지하며 V- 벨트(1)의 몸체 내부에는 공간부(6)가 형성되어 있으며 공간부(6)내에는 마찰접촉면(4)(5)이 풀리(2)측에 접촉하도록 힘을 가하는 압축스프링(7)이 내장되어 있다.The frictionally abutting surfaces 4 and 5 on both sides of the V-belt 1 are maintained at approximately 38 ° to 40 ° and the space 6 is formed in the body of the V- A compression spring 7 is provided to apply a force such that the friction contact surfaces 4 and 5 come into contact with the pulley 2 side.
도면중 부호 8은 V-벨트의 고무몸체와 압축스프링(7)사이에 개재된 지지부재로서 마찰접촉면(4)(5)에 스프링(7)의 힘을 고르게 분산하는 역할을 한다.In the figure, reference numeral 8 denotes a support member interposed between the rubber body of the V-belt and the compression spring 7 and serves to evenly distribute the force of the spring 7 to the friction contact surfaces 4 and 5.
이와같은 구성에 의하면 압축스프링(7)의 탄발력으로 마찰접촉면(4)(5)이 바깥측으로 팽출하게 되어 풀리(2)와의 접촉면압을 크게 증대시키게 된다.According to this configuration, the friction contact surfaces 4 and 5 are bulged outward due to the resilient force of the compression spring 7, so that the pressure on the contact surface with the pulley 2 is greatly increased.
이상과 같은 본 발명의 V-벨트에 의하면 몸체 내부에 내장된 압축스프링이 마찰접촉면을 바깥측으로 팽출시켜 풀리와의 접촉면압을 증대시키게 되므로써 동력 전달 성능이 향상되어 큰 동력 전달의 요구시에도 적은 개수의 V-벨트 사용이 가능하여 레이아웃을 향상시키게 되는 효과가 있다.According to the V-belt of the present invention as described above, the compression spring built in the inside of the body bulges outward to increase the pressure of the contact surface with the pulley, thereby improving the power transmission performance, It is possible to use the V-belt of the present invention, thereby improving the layout.
