Embodiment Construction

[0021] Hereinafter, an example of an embodiment of the power transmission device according to the present invention will be described in detail with reference to the drawings.

[0022] Figure 1 ~ Figure 3 The reduction gear G1 (power transmission device) according to an example of the embodiment of the present invention is described in various directions or cross-sections.

[0023] in addition, image 3 (A) relative to figure 2 (A) is not a rear view viewed from the back while maintaining the vertical direction, but a rear view viewed from the rear while maintaining the left-right direction (inverted in the vertical direction).

[0024] The reduction gear G1 is used in connection with a motor (not shown) through a relay case 12 , starting from the outline.

[0025] The reduction gear G1 includes a gear reduction mechanism 14 and a housing 16 that accommodates the gear reduction mechanism 14 .

[0026] The gear reduction mechanism 14 includes an input shaft 18, a hypoid p...

Abstract

The present invention provides a power transmission device and a manufacturing method thereof, which can suppress a decrease in strength or rigidity as much as possible while using a lightweight and low-cost resin casing. The reduction gear (G1) of the present invention includes: a gear reduction mechanism (14) having an input shaft (18), a hypoid pinion (20) provided on the input shaft, a rotating shaft (22) other than the input shaft, and A gear (24) assembled on the rotating shaft; a casing (16) for accommodating the gear reduction mechanism, wherein the casing is made of resin, and has: a casing main body (30) having an assembly opening (26) for assembling the gear ); the cover (32), which closes the assembly opening, and the housing main body also has an input side opening (34) of a size that the hypoid pinion can be inserted through but the gear cannot be inserted through, and the rotating shaft is formed on the housing main body The first and second bearing support parts (36-39) support, and the bearing support part of the rotating shaft is not formed in the cover body.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2012-237320 filed on October 26, 2012. The entire content of this application is incorporated in this specification by reference. [0002] The invention relates to a power transmission device and a manufacturing method thereof. Background technique [0003] Patent Document 1 discloses a power transmission device including: a gear reduction mechanism having an input shaft, an input pinion provided on the input shaft, a rotating shaft other than the input shaft, and a gear assembled to the rotating shaft; and a housing , which houses the gear reduction mechanism. [0004] Such a power transmission device has conventionally used an aluminum or casting housing. Alternatively, for example, a power transmission device used in a food factory or the like may use a stainless steel case. [0005] Patent Document 1: Japanese Patent Laid-Open No. 2011-144904 [0006] However, in a power...
