Problems solved by technology

[0007] Here, the actual situation is that although the main bearing with an enlarged diameter is one of the parts that increase the cost, it is also a part that affects the allowable moment by its nature, so it is not shared, but is classified by size and individual design

Embodiment Construction

[0021] Hereinafter, a series of eccentric oscillating speed reducers according to an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] The reducer series consists of a first sub-series and a second sub-series, the first sub-series consists of a plurality of reducers with a hollow part with a larger hollow diameter, the second sub-series consists of a A series of hollow parts with a hollow diameter of the hollow part (specifically, the minimum diameter of the hollow part is zero, that is, there is no hollow part) consisting of a plurality of reduction gear units.

[0023] figure 1 It is a cross-sectional view showing an example of a reduction gear having a hollow portion with a large hollow diameter belonging to the first sub-series (hereinafter, appropriately referred to as the first reduction gear G1), figure 2 It is a cross-sectional view showing an example of a reduction gear without a hollow part (hollo...

Abstract

The present invention provides a series of eccentrically swinging reducer, which can realize common usage of a main bearing of the eccentrically swinging reducer, so as to reduce costs of the series. The series of the eccentrically swinging reducer is composed of a plurality of reducers of different sizes determined according to the size of the torque. The series is provided with a first sub-series composed of reducers with hollow parts, and a second sub-series composed of reducers with hollow parts whose hollow diameter is smaller than the hollow diameter of the hollow parts of the first series or without hollow parts under the same size, and main bearings (135, 136) for supporting wheel carrier bodies (124, 128) of the specific reducers of the size in the first sub series are used in common with the main bearings (235, 236) for supporting wheel carrier bodies (224, 228) of the specific reducers of the size in the second sub series.

Description

technical field [0001] The invention relates to a series of eccentric swing speed reducers. Background technique [0002] Patent Document 1 discloses an eccentric oscillating speed reducer. In this reduction mechanism, an external gear (planetary gear) supported by a carrier body meshes with an internal gear while swinging, and outputs relative rotation of the two gears generated during the meshing. Usually, the relative rotation of the internal gear and the external gear is output as the relative rotation of the housing and the carrier body. Therefore, the housing and the carrier body are set to be able to rotate relative to each other via the largest bearing called "main bearing". [0003] In order to meet various requirements of users, various types of this reducer are prepared. For example, in applications such as industrial robots, it is considered that a pipe or a rod needs to be penetrated through the center of the reducer, and a reducer having a hollow portion wit...
