Abstract
Disclosed herein is a rotation transmitting device which permits the transmission of rotation with a reduced play and which permits the constituents to be aligned easily. The rotation transmitting device has a transmitting member (30) which surrounds a rotating part (12) of a drive shaft (11) and a rotating part (22) of a driven shaft (21). At least either the rotating part (12) of the drive shaft (11) or the rotating part (22) of the driven shaft (21) has an external surface that comes into contact with the internal surface of the transmitting member (30) so that friction arising between the internal surface and the external surface achieves torque transmission and reception to and from the transmitting member (30).
Claims8
A rotation transmitting device comprising:
- a first rotating shaft having a first rotating part having a first external surface;
- a second rotating shaft having a second rotating part having a second external surface, and the second rotating shaft being arranged in a direction intersecting with said first rotating shaft;
- a transmitting member having an internal cylindrical surface surrounding and engaging both said first external surface of the first rotating part and said second external surface of the second rotating part;
- an intermediate transmitting member having a cylindrically-shaped external surface, and being arranged such that the cylindrically-shaped external surface is in rotatable communication with both the first external surface of the first rotating part and the second external surface of the second rotating part, wherein
- said first rotating part transmits rotation to said transmitting member and to said intermediate transmitting member,
- said second rotating part receives rotation from said transmitting member and from said intermediate transmitting member, and
- the rotation is transmitted between said first rotating part and said second rotating part by way of:
- friction between the internal cylindrical surface of the transmitting member and the first external surface of the first rotating part and the second external surface of the second rotating part, and
- friction between the cylindrically-shaped external surface of the intermediate transmitting member and the first external surface of the first rotating part and the second external surface of the second rotating part.
