no. 1 Embodiment approach
[0017] The gap between the swing gear and the carrier is a portion through which debris detached from the crankshaft assembly easily passes. In the first embodiment, an exemplary stopper structure for preventing debris from passing through the gap between the swing gear and the carrier will be described.
[0018] figure 1 and figure 2 The speed reducer 100 exemplified as the gear device of the first embodiment is shown. figure 1 is a schematic cross-sectional view of the speed reducer 100 . figure 2 is the reducer 100 along the figure 1 A schematic cross-sectional view along line A-A is shown. refer to figure 1 and figure 2 The speed reducer 100 will be described.
[0019] The speed reducer 100 includes an outer cylinder 200, a gear carrier 300, a gear unit 400, and three crankshaft assemblies 500 ( figure 1 One of three crankshaft assemblies 500 ) and two main bearings 610 , 620 are shown. Driving forces generated by a motor (not shown) and other driving sources (...
no. 2 Embodiment approach
[0051] As described in connection with the first embodiment, through-holes are formed in the carrier and the swing gear along the output axis. The central space formed by the through-holes of the carrier and the swing gear may also be used for connection between the crankshaft assembly and the motor and for electrical wiring. Floating objects which could damage the gear reducer and / or which could lead to sudden locking of the gear reducer sometimes also enter the gear reducer via the central space. Alternatively, fragments generated inside the reducer sometimes fly out of the reducer from the central space. In this case, the debris may damage other devices arranged around the speed reducer. Thus, it is preferred that the blocking formation separates the central space from the other spaces. In the second embodiment, a blocking structure for partitioning the central space from other spaces will be described.
[0052] Such as figure 1As shown, the central through hole 411 for...
no. 3 Embodiment approach
[0058] The design principles described in connection with the first and second embodiments contribute to preventing movement of debris between movable parts within the speed reducer (ie, the carrier and the oscillating gear). Fragments detached from the crankshaft assembly may fly out of the speed reducer from the end of the storage space in which the crankshaft assembly is accommodated. Fragments flying out of the reducer may damage other devices arranged around the reducer. In 3rd Embodiment, the stopper structure which closes the edge part of a storage space is demonstrated.
[0059] Such as figure 1 As shown, the speed reducer 100 further includes a closing cover 710 that closes the holding through hole 316 formed in the base plate portion 311 . The closure cover 710 includes a bottom wall 711 and a peripheral wall 712 . The bottom wall 711 is substantially disc-shaped. The peripheral wall 712 is a substantially cylindrical portion protruding from the outer edge of the...
