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 comprising friction rollers comprising a sun roller 30, a planetary roller 34 and a ring roller 36, which are held on a planetary carrier and rotate with the outer circumference of the sun roller contact, the planetary rollers are in rotational contact with the inner circumference of the ring roller while restricting 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

Abstract

A friction transmission device including a simple planetary roller mechanism with sun rollers, planetary rollers and ring rollers, and a brake. The static friction torque Y and the experimental torque value Xd when slipping rotation is initially generated on any friction roller are set as 0.1Xd<Y<0.7Xd. The fastening force of the ring roller is set so that the critical experimental torque Xd is equal to 1.4-10.0 times the static friction torque Yd of the brake. Set the static friction torque Y and the critical friction torque Xd to Y<0.7Xd, set the dynamic friction torque Ys at the rated speed and the limit transmission torque Xs of the simple planetary roller mechanism when the sun roller rotates at the rated speed to 0.65 Ys<Xs<3.4Ys.

Description

technical field [0001] The invention relates to a friction transmission and a method for manufacturing the friction transmission. 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 drive 1 has a simple planetary roller mechanism 10 (not shown in its entirety) arranged in a housing 9 . This simple planetary roller mechanism 10 is equipped with friction rollers including a sun roller 2, a planetary roller 6 which is in rotational contact with the outer periphery of the sun roller 2, and a ring roller 8 which rotates on the inner periphery of the sun roller In contact, the ring roller 8 limits itself to rotation. In addition, the planetary carrier 4 and the simple planetary roller mechanism 10 are connected together by inserting support pins into the planetary rollers 6 . ...
