Problems solved by technology

[0006] However, as mentioned above, if the output shaft of the continuously variable transmission is connected to the rotating shaft of the driven part through the transmission belt, the transmission of the rotational speed will be affected due to the micro vibration generated on the transmission belt or the slippage of the transmission belt. Accuracy, in turn, may produce defects (woven segments) that affect fabric quality
[0007] In addition, in the past, the ou...

Abstract

The present invention provides a gearless drive mechanism, facilitating the connection between an output shaft of a continuously variable transmission and a rotating shaft of a driven body, and transmitting the rotating speed of the output shaft to the rotating shaft of the driven body with good accuracy. The gearless drive mechanism includes: an input shaft 4 rotating on receiving the driving force; an output shaft 5, one end of which is connected to the input shaft through a variable speed mechanism, the other end being projected from a casing; a first gear 42 disposed outside the casing 3 to be spline-coupled to the projecting part of the output shaft 5 and rotated in a body with the output shaft 5; and a second gear 44 rotatablely supported on the casing 3 through a support shaft 43 to mesh with the first gear 42.

Description

technical field [0001] The present invention relates to a continuously variable transmission that changes the rotational speed of a driving source, and in particular to a loom that is rotated by the driving force of a drive motor and that changes the rotational speed of a warp shaft around which warp yarns are wound according to the tension of warp yarns CVT. Background technique [0002] Conventionally, there is known a continuously variable transmission having a structure in which an input shaft and an output shaft are provided in a housing, and the driving force of the output shaft is transmitted to a driven member, and the input shaft is rotated by the driving force of the driving motor. , one end of the output shaft is connected to the above-mentioned input shaft through a transmission mechanism, and the other end protrudes from the above-mentioned housing. [0003] In addition, in the past, in the loom, the drive part that sends out warp yarn has following stepless tr...
