JPS5917044A - Belt for stepless speed change gear - Google Patents

Abstract

PURPOSE:To enable a stepless speed change for the power transmission between two shafts crossing at a right angle or between two shafts not in parallel by protruding the center of the side face of a disk block inserted on an annular wire rope. CONSTITUTION:A disk block 12 is provided with a hole in which a wire rope 11 is inserted at the center, and one side or both sides are swelled in a convex shape. The disk blocks 12 are inserted and arranged with no gap on the wire rope 11. The power transmission between two shafts not in parallel can be freely accomplished by using a guide capable of being bent in any direction such as a wire rope 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuously variable transmission between two orthogonal axes or two axes at an angle.

Conventionally, there are many ways to transmit power between orthogonal axes or axes that are not parallel and are at a certain angle, such as using bevel gears, screw gears, worm gears, and flat belts, but these -Continuously variable speed is not possible between driven shafts.

Seven examples of continuously variable transmission mechanisms between non-parallel co-axes have conventionally existed as shown in FIGS. 1 and 1.

However, in these continuously variable transmissions, the distance between both shafts is close, and if there is a distance, the above mechanism cannot be used.

In view of the above circumstances, the present invention provides a belt for silently and steplessly changing the speed of power transmission between two orthogonal axes or between two axes that are not parallel.

explain.

The belt according to the present invention (aspect 4) is as shown in Fig. 3, in which disc blocks (/) are inserted and arranged without any gaps in an endless wire rope (//). A block (must have a hole (/J) in the center, a convex bulge on one or both sides, and is made of a material hard enough to withstand the propulsive force generated by the power to be transmitted. On the other hand, wire lobes (//) are made by twisting many thin wires, and are extremely durable against the bending that occurs when wrapped around a V-shaped pulley.

However, the above-mentioned wire rope (//) is not limited to metal, and rubber-based reinforcing wire or the like may also be used. These disc blocks (/J are simply inserted into wire ropes (//) and can move freely. Furthermore, they can be continuously variable between two shafts that are parallel to each other. If available, use the wire rope (//) mentioned above or rubber-based reinforced wire, etc.Even if it is not something that can be bent in all directions, it is a chain that can only be bent in one direction (for example, link play as shown in Figure S and Figure S). It may be a leaf chain (/7) consisting of a combination of C1, t') and a pin (/4), a roller chain, a bush chain, or the like.

By the way, to explain the function of the belt (1) according to the present invention, as shown in FIG.
→ It is hung on a rack via.

Main drive side boo! When J-(,2) rotates, the disk block (/) in contact with the pulley inclined surface (/υ) is moved by friction, and the forward disk block (/2) is propelled.

In other words, the propulsive force generated by the frictional force with the pulley inclined surface (//D) is transmitted to the disc block (/2) one after another using the wire rope (//) as a guide, and the driven pulley (3)
will be rotated. In this case, the wire rope (
//) has an initial tension to prevent the belt (1) from becoming loose, a disc block (/2) and a wire rope (//
) only the friction between them creates no tension for power transmission.

Leaf chain (/7) instead of wire rope (//)
) etc., power transmission between parallel shafts is possible by using the leaf chain (/) as a guide to propel the disc block (/J).

As described above, the present invention is a wire rope (//), sometimes a chain (t), and a disk block (/j) having a convex shape on both sides or one side, which are inserted and arranged without any gaps between each other, and each of the driving shaft and driven shaft. By hanging it on a V-shaped pulley, it is possible to smoothly and steplessly change speed transmission.In addition, by using a wire rope (/θ) guide that can be bent in all directions, it is possible to Power transmission is also free.
