Problems solved by technology

[0006] However, in conventional gear motor connectors including the connector disclosed in Patent Document 1, the locking surface on the carrier side and the locking surface on the motor side are each formed as a stepped portion formed on a surface opposite to the axial direction. , so machining must be done separately from the respective side (machining of the re-clamped material)
Therefore, it is difficult to accurately match the axes of the locking surface on the carrier side and the locking surface on the motor side. As a result, the rotation axis of the motor shaft of the motor tends to deviate from the rotation axis of the carrier of the planetary gear device. question

Embodiment Construction

[0019] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0020] figure 1 It is an overall cross-sectional view showing the gear motor 10 for a machine tool according to the present invention.

[0021] The gear motor 10 is connected to a planetary gear reducer (planetary gear unit) 12 and a motor 14 via a connector 16 .

[0022] The description will be made from the planetary gear reducer (planetary gear unit) 12 .

[0023] The planetary gear reducer 12 is a so-called oscillating internal mesh type reducer, and is provided with three eccentric bodies 21 to 23 integrally with the input shaft 18 . The eccentric directions of the eccentric bodies 21-23 deviate by 120 degrees respectively, and are only eccentric relative to the axis O1 of the input shaft 18 by δe (for convenience, figure 1 In , a state where the left eccentric body 21 is eccentric to the lowermost side and a state where the right eccen...

Abstract

The gear motor (10) has support portion (43) whose convex portion (50) is extended axially to side of adapter (16). A first mating surface (X1) is formed on outer periphery of support portion. A second matting surface (X2) is provided at convex portion (64) of motor (14). A first mating fitting surface (Y1) is provided on an inner periphery (16A1) at one end side of through-hole (16A) corresponding to first mating surface.A secont mating fitting surface (Y2) is formed on inner periphery (16A2) at other end side of through hole corresponding to second mating surface.

Description

technical field [0001] The invention relates to a gear motor and a connector for the gear motor. Background technique [0002] Patent Document 1 discloses a so-called frame rotation type planetary gear device in which a carrier of the planetary gear device is fixed and a housing integrated with an internal gear is rotated. In this planetary wheel device, a motor as a driving source is fixed to the wheel carrier. [0003] The connector is interposed between the motor and the wheel frame, mediating the connection between the motor and the wheel frame. A side surface of the connector on one side in the axial direction forms a stepped portion as a locking surface opposite to the wheel frame, and a stepped portion is formed on the other side in the axial direction as a locking surface opposite to the motor. [0004] That is, in this gear motor connector, the axis center of the motor shaft of the motor coincides with the axis center of the carrier of the planetary gear device du...
