Claims

[Claims for Utility Model Registration] (1) An annular driven wheel having endless external teeth on its outer peripheral end surface, and an annular driven wheel having a smaller diameter than the inner diameter of the annular driven wheel and located on the inner peripheral side of the annular driven wheel. However, there is a drive disk which integrally has a drive shaft in the center and a plurality of bushes that are equally spaced around the drive shaft and protrude in the side direction, and a drive disk which is centered on the side surface of the annular driven wheel. A large window is provided through which the drive shaft passes, and a bush window with an inner diameter larger than the diameter of the bush is provided at a position equidistant from the center and corresponding to each bush protruding from the drive disk, and a bush window is provided within the bush window. a side plate that is integrally attached to the annular driven wheel so as to loosely fit the drive disk onto the inner circumferential side of the annular driven wheel so that each bush of the drive disk faces, and to cover the side surface of the annular driven wheel; and the annular driven wheel. It consists of a toothed belt wound between power transmission pulleys, and each bush protruding in the side direction of the drive disk is overlaid with an elastic ring having a diameter somewhat larger than that of the bush. A belt-type power transmission device characterized by: (2) In the utility model registration claim described in claim 1, the plurality of bushings protruding in the lateral direction of the drive disc are provided on both left and right sides of the drive disc, and a side plate having a bushing window is provided. This is a belt-type power system in which each bush of the drive disc faces into each bush window to cover both left and right sides of the annular driven wheel with the drive disc sandwiched between them, and the drive disc is fitted loosely into the inner circumference of the driven wheel. transmission device. (3) In the utility model registration claims 1 to 2, the bush protruding from the side of the drive disk has a rotatable roller on its outer circumferential surface. Belt type power transmission device. (4) In the utility model registration claims 1 to 3, a side cover that can cover at least each bushing window of the outer side plate is provided on the outer side of the side plate that covers the side of the annular driven wheel. A belt-type power transmission device that is attached to a belt. (5) In the utility model registration claims 1 to 4, the annular driven wheel and the side plate covering the side surface thereof are integrally molded in advance and can be divided into two at the center of the annular driven wheel. Belt-type power transmission device configured.
