Embodiment Construction

[0079] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0080] figure 1 It is a partial cross-sectional view showing a friction transmission device 20 according to an embodiment of the present invention. The friction transmission is equipped with a simple planetary roller mechanism 28 as friction rollers with a sun roller 30, a planetary roller 34 and a ring roller 36, which are held on the transmission gear and are in rotational contact with the outer circumference of said sun roller, which the planetary rollers are in rotational contact with the inner circumference of the ring roller while limiting the ring roller's own rotation; and

[0081] The brake 22 is connected with the sun roller 30 and brakes the rotation of the sun roller 30 .

[0082] The static friction torque Y obtained from the brake is set to 0.1Xd

Description

technical field [0001] The invention relates to a friction transmission rotary drive. Background technique [0002] Friction drives with simple planetary roller mechanisms have long been known. [0003] exist Figure 8 An example of such a conventional friction transmission is schematically drawn in . The friction transmission device 1 is equipped with a sun roller 2, a planetary roller 6 in rotational contact with the outer circumference of the sun roller 2, and a planetary roller 6 on its inner circumference in the housing 9 (not entirely drawn) of the simple planetary roller mechanism 10 The ring roller 8 which is in contact with the upper rotation and at the same time limits its own rotation. In addition, the gear 4 is connected to the simple planetary roller mechanism 10 by inserting support pins into the planetary rollers 6 . [0004] The friction conventional device 1 has a sun roller 2 or a gear 4 as a power input / output element and a ring r...
