Problems solved by technology

[0008] (2) In the field of fine processing that requires prohibition of particles, such as semiconductor wafer or LCD (liquid crystal display) glass substrate processing, the conveyed material must not be conveyed (cannot be held) by clamping (holding the conveyed material)
However, in the DD system drive unit, since the output density (torque / volume, torque / motor power) is small, there is a problem that the drive unit is large and the power supply power is also large
Therefore, there is a problem that the load capacity cannot be increased

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 is a first embodiment of a conveying device 60 using a traction drive speed reducer according to the present invention, Figure 1A is a typical cross-sectional view for showing the structure of this embodiment, Figure 1B is along Figure 1A Cross-sectional view of line A-A in. At this point, although the circumscribed shaft, the intermediate shaft and the inscribed roller are actually in contact with each other, at Figure 1A A small gap is shown between them for clarity. In addition, in Figure 1B , the view of the bracket is omitted.

[0043] In this example, if Figure 1A As shown, the bracket 10 of the present invention is formed into a box shape by upper and lower plates 11 and 12, and a support portion 13 is connected between the two plates. An output shaft 21 is provided at the center of an output circumscribed shaft 20 in a protruding manner, and the o...

Abstract

A traction drive speed reducer includes a circumscribed shaft (20A, 20B), a plurality of intermediate shafts (30A, 30B) arranged in contact around the outer circumference of the circumscribed shaft, and an inscribed roller (40A, 40B) connected to the outer circumference of the intermediate shaft ), wherein the supporting member (10) rotatably supporting the intermediate shaft is fixed, a drive motor is connected to at least one of a plurality of intermediate shafts, and the output is taken from a circumscribed shaft whose diameter is greater than the outer diameter of the intermediate shaft.

Description

technical field [0001] The invention relates to a traction drive reducer, which comprises an external shaft, a plurality of intermediate shafts arranged in contact around the outer circumference of the outer shaft, and an inner drum innerly connected to the outer circumference of the intermediate shaft. [0002] The present invention also relates to a conveying device, which uses a traction drive reducer as a driving device, and the reducer includes a circumscribed shaft, a plurality of intermediate shafts arranged in contact around the outer circumference of the circumscribed shaft, and an internally connected intermediate shaft Inscribed rollers on the outer circumference. [0003] The invention also relates to a dual-axis encoder structure used in a conveying device. Background technique [0004] (1) In a traction drive reducer including a circumscribed shaft, a plurality of intermediate shafts arranged in contact around the outer circumference of the circumscribed shaft...
