この発明は、動力伝達用Vベルト、特に可変直径Vプー

。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a V-belt for power transmission, particularly to a V-belt for power transmission used in a variable diameter V-pulley.
例えば、重両用のVベルト式無段変速機等の可変直径V
プーリに使用されるこの種の動力伝達用Vベルトとして

いる。For example, the variable diameter V of a V-belt type continuously variable transmission for heavy duty use, etc.
Examples of the configuration of this type of V-belt for power transmission used in pulleys have been disclosed, for example, in Japanese Patent Publication No. 55-6783 and Japanese Patent Application Laid-Open No. 58-81252.

のである。The structure of these V-belts is that a metal band consisting of a stack of a plurality of endless metal bands is connected to a plurality of adjacent V-belts.
It is assembled so as to be supported by shaped metal members (blocks).

あるため、l滑油が供給が困難であるという問題点があ
った。A detailed explanation of the V-belt configuration in the conventional proposed example as described above will be omitted to avoid duplication with the cited document, but when these V-belts are wound around a variable diameter V-pulley and rotated, the belt The swinging fulcrums between the adjacent V-shaped metal members due to curvature are both below the lower surface (inner surface) of the band (in the direction of the center of the pulley), and therefore support the band of each V-shaped metal member. The contact support surfaces for the band have the drawback that the rocking movement causes relative slippage, and also slippage between the individual layers of the band. Furthermore, since the swing fulcrum is located in the F direction from the bunt contact surface, there is a problem in that it is difficult to supply lubricating oil.
以上の欠点を改良する案として、例えば実開昭58−2
0751号公報に一改ぷ提案例が開示されている。As a plan to improve the above-mentioned drawbacks, for example,
An example of a proposed revision is disclosed in Publication No. 0751.

ぼ一致するようにしたため、前記従来例欠点は解消され
る方向にあるが、反面つぎのような大きな欠点があった
。The detailed explanation of the configuration according to this proposed example is also omitted in favor of the above cited document, but this method is based on each adjacent V-shaped metal member (
Since the position of the swinging fulcrum between the blocks (blocks) is made to almost match the height of the belt abutting surface, the drawbacks of the prior art example described above are likely to be overcome, but on the other hand, there are the following major drawbacks.
すなわち、

に高く弯曲している(前記引用公報第6図21d)ため

ンドの寿命に悪影響を及ぼす欠点がある。That is, (1) In this proposal, since the structure is such that there is a space (gap) between each adjacent V-shaped metal member,
In the pulley rotation state where each member is in contact with the V groove surface of the V pulley, the band takes on a polygonal shape due to the space, and the center part of the belt support contact surface of each V-shaped metal member is highly curved in an arc shape. (see Figure 21d of the cited publication), there is a part that generates high stress in the abutting band, which has the disadvantage of having a negative effect on the life of the band.

When the bunt is assembled to these, the recess is located at approximately the same height and on the same pulley radius as the contact support surface on the lower surface of the band,
In addition, since both upper (outside) sides of the protrusions of each V-shaped metal member are parallel to each other, there is no flexibility in belt curvature, and the V-shaped belt after ItL is not assembled correctly. The drawback is that metal members are difficult to assemble.
(3)また上記のように、各V形金属部材のバンド組付

。(3) Also, as mentioned above, since both upper (outer) side surfaces of the band assembly part of each V-shaped metal member are in contact with each other in parallel planes, the vertical direction when the V-belt runs in a straight line is Since the V-belt only curves in one direction in response to vibrations, it has the disadvantage that a strong tension is applied to the band against the inward warping of the V-belt.

Vベルトの提供を[1的としている。This invention was made in view of the problems in the conventional proposals as described above, and it substantially eliminates the gaps between adjacent V-shaped metal members, without causing high local stress on the band. [1] It is an object of the present invention to provide this type of V-belt, which is advantageous in terms of belt wear and service life, and also has good V-belt assemblability.

mutual contact between each adjacent V-shaped metal member of the belt;
The arcuate convex portion of the longitudinal side end E of the band, which is substantially centered on the lower contact surface of the band and is above the center line, is brought into contact with the flat portion of the adjacent V-shaped metal member, and The above object is achieved by configuring the lower part of the belt contact support surface to be brought into contact with a semi-cylindrical recess and a protrusion each having an axis in the band width direction.

なく、ベルトの摩耗や寿命上効果的である。That is, (1) Regarding the influence of polygonalization of the band in the conventional example due to the existence of gaps (spaces) between outer adjacent V-shaped metal members, between each first V-shaped metal member 2, the arcuate convex portion 2a and the mating vertical plane part 2d are in contact with each other and there is no gap between the adjacent members, so the band 1 does not become polygonal, and high stress is not generated on the inner surface of the band 1, and the belt Effective in terms of wear and service life.

the inner (lower) side of the first V-shaped metal member 2 above/below the band 1 attachment part forms an inclined surface 2e;
Since the outer (upper) side 2f is retracted from the arcuate convex portion 2a, it is visible in both upward and downward directions, and the belt can be tilted to both sides. At the mounting location, since the radius of the roller member 3 is larger than the depth of the recesses 2Aa and 2Ac, a slight gap can be formed above and below (inside and outside) the adjacent second V-shaped metal member 2A. Even if the mutual inclination toward the outside of the band 1 at one location between adjacent members is minute, by modifying several parts of it, great flexibility can be obtained, and the V-shaped metal member to be assembled at the end can be easily assembled. Can be assembled.

止しj:lる。Furthermore, as another general feature, the shape of the V-shaped metal member can also be manufactured using a sintered alloy. For example, a small part with a complex shape like the one shown in the example can be manufactured at low cost using an iron-based sintered alloy. In addition, by utilizing the porous properties of the sintered alloy as a so-called oil-impregnated metal, it has a lubricating function against high surface pressure and contact sliding, and prevents seizure and the like.

We were able to provide a V-belt for power transmission.
