ギヤドモータ及びギヤドモータシリーズ
Document Type and Number:
Japanese Patent JP4368013
Kind Code:
B2
Abstract:
A geared motor (30, 72, 84, 104, 116) in which user needs for change gear ratios are met with flexibility and reliability, and an increase in noise is suppressed. The geared motor (30, 72, 84, 104, 116) comprises a motor unit (2) and a change gear unit (4, 80, 88, 108, 120) for transmitting rotational power from this motor unit (2) in combination. A simple planetary roller unit (36, 70) including a simple planetary roller mechanism (32) and a casing (34) for accommodating this simple planetary roller mechanism (32) is interposed between the change gear unit (4, 80, 88, 108, 120) and the motor unit (2). The simple planetary roller mechanism (32) has a sun roller (38), planetary rollers (50), and a ring roller (52). Flange portions (62A, 62B) spreading outward in the radial directions of the sun roller (38) are formed on both axial ends of the casing (34). One of the flange portions is coupled to the motor unit (2), and the other is to the change gear unit (4, 80, 88, 108, 120). Moreover, the geared motor (30, 72, 84, 104, 116) is configured so that rotational power from the motor unit (2) is transmitted to the change gear unit (4, 80, 88, 108, 120) through the simple planetary roller unit (36, 70).
