Abstract

PURPOSE:To minimize the side shifting quantity of a metal belt and reduce the width of the belt and the width of each pulley by making the difference between the crown R quantity of an idle pulley and the crown R quantity of a drive pulley at least 20mm or more. CONSTITUTION:A metal belt 3 is stretched between a drive pulley 1 and an idle pulley 2 and the idle pulley 2 is driven by the drive of the drive pulley 1. At this time, the difference between the crown R quantity of the drive pulley 1 and the crown R quantity of the idle pulley 2 is set to be 20mm or more as, e.g., R 180mm, 90mm from an experimental result. Thereby, the side shifting quantity of the metal belt 3 is suddenly reduced to minimize the width of the metal belt 3 and the width of each pulley 1, 2, enabling equipment to be miniaturized.

2. Description of the Related Art Conventionally, a belt drive system has been commonly used in which a belt is stretched between a drive pulley and an idle pulley, and the idle pulley is driven via the belt when the drive pulley is activated.

Since the belt in such a drive system is made of an elastic material (1) and usually a high-strength rubber body, there are drive errors (1), such as disturbances in the drive speed due to elongation or aging of the rubber body, and rotation errors, which cannot be resolved. For this reason, metal plate belts have recently been used.

However, although the above-mentioned metal belt is stable against elongation and aging, it is prone to lateral slippage due to the occurrence of alignment angles while sliding between pulleys.
The situation was such that it was necessary to use a boob that was much wider than the belt width.

The widening of the belt width as described above is uneconomical due to the ``sA'' structure, and also requires space in the assembly structure-L, which goes against the trend of miniaturization.

For this reason, countermeasures have been taken by reducing the width of the boob and attaching a crown R to one of the boobs, or by attaching the same crown R to both boobs.

即ち、金属ベルトの横ずれを防止するために。In other words, to prevent the metal belt from shifting laterally.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a metal belt stretched between a drive pulley and an idle pulley, and when the drive pulley is started, the metal belt is connected to the idle pulley via the metal belt. In the metal belt drive system, both crowns are formed so that the difference between the crown R-1"t of the idle pulley and the crown [< amount of the drive pulley is at least 20 mm or more. It is characterized by this.

However, if the crown amount of one of the two types of pulleys (drive pulley 1 and idle pulley 2) is Ro and the crown h1 of the other is [<1, then under the condition of Ro>R1, the amount of M = Ro − Ill >M within the range of O
It can be seen that as rt-2 increases, the amount of lateral deviation decreases rapidly, and this tendency is particularly severe at M m of 220 mm.
