Embodiment 1～3、 comparative example 1

[0146] The same rubber composition was used in each of the Examples and Comparative Examples to produce a V-ribbed belt having a belt width of 10 mm, a rib number of 3, and a rib height of 2.5 mm.

[0147] A laser processing machine is used on the entire surface of the rib-forming surface in this V-ribbed belt to Figure 10 (Embodiment 1), Figure 11 (Embodiment 2), Figure 12 (Embodiment 3) to form the groove.

[0148] in addition, Figure 10-13 It is a micrograph of surface observation using a microscope.

[0149] In Example 1, grooves having a width of approximately 80 μm (sections with grooves: approximately 1100 μm; sections without grooves: approximately 900 μm) were formed at a pitch of 250 μm. In Example 2, grooves with a width of approximately 80 μm were formed at a pitch of 250 μm. 150 μm linear groove.

[0150] Furthermore, in Example 3, linear grooves having a width of approximately 80 μm were formed in a grid pattern at a pitch of 250 μm in the vertical and h...

Abstract

A V-ribbed belt has less slip and noise when it is overwashed. The V-ribbed belt has a rib forming surface where ribs extend in the longitudinal direction of the belt and is used with the rib forming surface made to be in contact with a pulley. The V-ribbed belt has a non-contact region not coming into contact with the pulley when the belt is driven. A depression is formed in the rib forming surface so as to allow water to flow into the non-contact region when the belt is overwashed.

Description

technical field [0001] The present invention relates to a multi-V belt having a wedge-forming surface formed with a plurality of ribs extending in the longitudinal direction of the belt. Background technique [0002] The V-ribbed belt is usually used between multiple pulleys. [0003] In addition, a V-ribbed belt usually has a rib forming surface formed with a plurality of ribs extending in the belt longitudinal direction, and when the belt is driven, the rib forming surface is brought into contact with a pulley to perform friction transmission. [0004] It is well known that, in a friction transmission using the V-ribbed belt, for example, when the V-ribbed belt and / or the pulley are wet, slippage occurs at the contact interface between the V-ribbed surface and the pulley, and abnormality occurs due to the slippage sound (noise). [0005] As a countermeasure against slipping when this water gets wet, the following methods have been studied (see Patent Document 1): forming...
