Embodiment Construction

[0014] figure 1 It is a schematic sectional view of the reduction gear transmission 100 according to one embodiment of the present invention. The deceleration device 100 is mainly a deceleration device for an extruder used to extrude a molten material.

[0015] The speed reduction device 100 includes a speed reduction mechanism 90 composed of a parallel shaft type four-stage speed reduction mechanism using a helical gear. The reduction mechanism 90 has an input shaft 52 , a first intermediate shaft 62 , a second intermediate shaft 72 , a third intermediate shaft 82 , and an output shaft 14 . The input shaft 52 and the three intermediate shafts 62 , 72 , and 82 in the reduction mechanism 90 are accommodated in the reduction gear case 20 . The output shaft 14 is housed in both the reduction gear housing 20 and the bearing housing 12 attached to one side of the reduction gear housing 20 . The internal space divided by the reducer housing 20 and the bearing housing 12 is filled...

Abstract

The present invention provides a speed reduction device, wherein the eccentricity between the speed reduction device and a driven machine is inhibited. The speed reduction device comprises a housing (12); an output shaft (14); a first bearing (16) used for supporting the output shaft on the load side, a second bearing (22) used for supporting the output shaft on the load-opposite side; and a force application part (24) used for driving the output shaft (14) to apply a force towards the thrust direction.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2015-034265 filed on February 24, 2015. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to a reduction gear. Background technique [0003] Conventionally, there is known a speed reduction device provided between a motor and a driven machine. For example, Patent Document 1 discloses a reduction gear transmission that includes: a housing for accommodating a reduction mechanism; an output shaft connected to an input shaft of a driven machine; a first bearing for supporting the output shaft on the load side; and a second bearing for The output shaft is supported on the opposite side to the load. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2014-169760 [0005] In the reduction gear transmission described above, for example, when a self-aligning bearing is used as the second bearing, the self-alignin...
