Problems solved by technology

For this reason, the diameter of the main bearing must be reduced, so the capacity of the main bearing becomes smaller, and the output torque or moment rigidity also becomes smaller.
In addition, when the diameter of the main bearing is increased, the planetary reducer itself will be enlarged

Embodiment Construction

[0018] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0019] figure 1 It is a sectional view showing a main part of a planetary speed reducer according to an example of the first embodiment of the present invention.

[0020] The planetary speed reducer 100 is a simple planetary gear mechanism, and includes a sun gear (not shown), a planetary gear 114 , a carrier body 120 , and an internal gear 134 in a case 136 . In addition, the housing 136 is divided into an output-side housing 138 as a housing connected to the target machine side of the planetary reducer 100 , and an input-side housing 137 as a housing on the opposite side of the target machine.

[0021] For example, a helical gear (may also be a spur gear) is provided on the sun gear, which meshes with the planetary gear 114 . The sun gear is connected to a motor shaft of an unillustrated motor via, for example, an unillustrated cylindrical ...

Abstract

The reducer has a skidding component / carrier body (120) synchronizing with a rotation component of a planetary gear, and an internal saw tooth gear (134) formed at an opposite side of a relativity machine (150). A casing unit (136) is provided in the relativity machine, and a main bearing i.e. taper roller bearing (128), supports a carrier. The planetary gear is supported by an oily pin, and a sub bearing i.e. taper roller bearing, supports the carrier. The main bearing is arranged in radius direction outer side of the carrier than the oily pin.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2009-203606 filed on September 3, 2009. The entire content of this application is used by reference in this specification. [0002] The invention relates to a planetary reducer. Background technique [0003] In the planetary speed reducer disclosed in Patent Document 1, the internal gear and the housing have a separate structure. Therefore, it is conceivable that in the planetary speed reducer shown in Patent Document 1, even if the housing has an inner diameter smaller than the outer diameter of the outer ring of the main bearing that rotatably supports the carrier body, between the main bearing and the target machine In some cases, it is also possible to increase the capacity of the planetary reducer without changing the connection form with the target machine. Here, in Patent Document 1, the ejector pin is press-fitted in the axial direction to fix the internal gear to the ...
