主な原因となつていた。By the way, in such a vertical reciprocator, the connector 8 has the sprocket 5,
The main cause of damage to the sliding body 2 is that, when passing through 6, the sliding body 2 connected to the connector 8 is subjected to a change in acceleration in the vertical direction according to the chain velocity and the load is accordingly added. I was told.

る。This will be described in more detail with reference to FIGS. Now, assuming that the endless chain 7 is driven at a constant speed of 70 m / min (1.167 m / s), when the connector 8 passes around the sprockets 5 and 6 with the sprocket angle θ passing from 0 ° to 180 °. The peripheral velocity V 1 of V is constant as V 1 = 1.167 m / s as shown by the characteristic line a in FIG. 2, but the vertical component V 1a of the peripheral velocity V 1 is V 1a =
V 1 · cos θ changes as shown by the characteristic line b in FIG. 3.

一定であつて、Ｖ1′＝０であるから、結局は、α1a＝
−Ｖ1 2・sinθ／ｒとなる。The vertical acceleration component α 1a generated in the connector 8 by the orbital motion is obtained by differentiating V 1a , and letting the radius of the sprockets 5 and 6 be r, α 1a =-
V 1 2 · sin θ / r + V 1 ′ · cos θ, and now V 1 is constant and V 1 ′ = 0, so α 1a =

The total vertical acceleration component α 1 generated in the connector 8 in which the above is added is α 1 = 9.8 on the upper driven sprocket 6 side.

When the vertical acceleration component α 1 when the sprocket angle θ on the driven sprocket 6 side is 0 ° to 180 ° is calculated as 0.091 m, it changes as shown by the characteristic line c in FIG. 4 (A).

やすい。In particular, as in this example, the radius r of the sprocket is relatively small, and the vertical acceleration component α associated with the orbiting motion is α.
When the maximum value of 1a exceeds 1 g, as is clear from the characteristic line c, the direction of the vertical acceleration component α 1 generated in the connector 8 is inverted up and down at the sprocket angle θ of about 40 ° and 140 °. , The direction of the force applied to the slide body 2 connected to the connector 8 is reversed, and the slide body 2 is easily damaged.

うになる。The total vertical acceleration component α 1 generated in the connector 8 on the lower drive sprocket 5 side is opposite to that of the upper driven sprocket 6 side because the direction of the vertical acceleration component α 1a accompanying the orbiting motion is opposite. 1 = 9.8 + V 1 2 · sin

The occurrence of 1 causes a large force to act on the sliding body 2 and also causes the sliding body 2 to be damaged.
