Abstract: A phase adjustment unit (100) for effecting phase adjustment between rolls of a multi-color printing press comprises a phase adjustment gear device (10) and a phase adjustment motor (6) fitted to the rear end of the gear device (10). The phase adjustment gear device (10) includes a hollow input shaft (12) inside a hollow casing (11) and an output shaft (14) inside the input shaft (12), and spline shafts (121, 141) for fitting are disposed at the distal ends of these shafts (12, 14). Cup type first and second wave motion gear devices (16, 25) are coaxially disposed at the rear end of the spline shafts, and input rotation returns to the first wave motion gear device (16) from an inner gear (161) of the first wave motion gear device through a gear train (30) and the second wave motion gear device (25), and is transmitted to the output shaft (14). While the motor (6) is locked, each constituent element of the first wave motion gear device rotates integrally, and the input and output shafts rotate in the same way. At the time of phase adjustment, the rotation speed of the motor (6) is drastically reduced and outputted through the gear devices (25, 16). Since the input and output shafts protrude from one of the sides, fitting and removal of the unit can be conducted easily.

Abstract: Disclosed is a variable compression ration mechanism (5) in which a control shaft (10) is rotated and driven by an electric motor (21) through a wave gear reducer (22). The wave gear reducer (22) includes: a first internal gear member (31); an external gear member (32) arranged concentrically inside the internal gear member (31); a wave generator (33) arranged inside the external gear member (32); and a second internal gear member (34), wherein a ratio of the number of teeth of a fixed gear portion (35) of the first internal gear member (31) to the number of teeth of a first gear portion (37) of the external gear member (32) is set lower than a ratio of the number of teeth of an output-side gear portion (42) of the second internal gear member (34) to the number of teeth of a second gear portion (38) of the external gear member (32). Thus, the tooth depth of the output-side gear portion (42) of the second internal gear member (34) is made relatively large so as to attain a higher ratcheting torque and prevent ratcheting.

Abstract: In a unit-type strain wave gearing (1), a rotating-side member (B), which is constituted by a second internally toothed gear (4) and an output shaft (5), is supported, via a first sliding bearing (8) and a second sliding bearing (9), on a fixed-side member (A) so as to be capable of relative rotation, the fixed-side member being constituted by a unit housing (2) and a first internally toothed gear (3). Sliding bearing surfaces (8b, 8c) of the first sliding bearing (8) and sliding bearing surfaces (9b, 9c) of the second sliding bearing (9) are defined by a conic surface having a central axis line (1a) as a center line. It is possible to realize a unit-type strain wave gearing which is advantageous in making smaller and more compact than when a roller bearing is used. It is also easier to adjust the gap between the sliding bearing surfaces because a radial sliding bearing having no function to adjust the radial gap is obviated.

The first and second external teeth (7, 8) are flexed by a wave generator by the same flexing amount, into an ellipsoidal shape.

Abstract: An externally toothed gear (4) of a dual-type strain wave gearing (1) is provided with first and second external teeth (7, 8) having different tooth numbers, and is flexed into an ellipsoidal shape by a wave generator. When the theoretical values (d 1 , d 2 ) of the radial flexing amounts at major-axis positions of the first and second external teeth (7, 8) flexed into the ellipsoidal shape are expressed by d 1 =m 1 n 1 and d 2 =m 2 n 2 (m 1 and m 2 represent the modules of the first and second external teeth, and n 1 and n 2 represent positive integers), the radial flexing amount (d) of the first and second external teeth (7, 8) flexed by the wave generator (5) satisfies d=(d1+d2)/ω (1.4 ≦ω≦ 2.6). Accordingly, a dual-type strain wave gearing can be achieved with which the first and second external teeth having different numbers can be suitably flexed to form excellent mating states with respective internally toothed gears.

Abstract: An externally toothed gear (4) of a dual-type strain wave gearing (1) is provided with first and second external teeth (7, 8) having different teeth numbers, and a gap (9) formed between these teeth as a cutter clearance area for tooth cutters. The maximum width L1 of the gap (9) is 0.1 to 0.3 times the width L of the externally toothed gear. The depth from the tooth top land of the first external teeth (7) to the deepest part (9a) of the gap (9) is 0.9 to 1.3 times the depth of the first external teeth, and the depth from the tooth top land of the second external teeth (8) to the deepest part (9a) of the gap (9) is 0.9 to 1.3 times the depth of the second external teeth. The tooth bottom fatigue strength of the externally toothed gear provided with differing numbers of first and second external teeth is increased, making it possible to achieve a strain wave gearing with high load capacity and small speed ratio.

Abstract: An externally toothed gear of a dual-type strain wave gearing is provided with first and second external teeth (7, 8) having different teeth numbers. The first and second external teeth (7, 8) are flexed by a wave generator by the same flexing amount, into an ellipsoidal shape. The average pressure angle (α1) of main-tooth-surface sections of tooth profiles (70) of the first external teeth (7) having a low teeth number is less acute than the average pressure angle (α2) of main-tooth-surface sections of tooth profiles (80) of the second external teeth (8) having a high teeth number.
