Title:
ROLLER BEARING TYPE MULTISTAGE TRANSMISSION
Document Type and Number:
Japanese Patent JPS5846252
Kind Code:
A
Abstract:
PURPOSE:To obtain a high speed change ratio by providing in multistage transmission mechanisms each of which uses an inner race as an input shaft and an retainer provided with a strength suitable for a required power transmission as an output shaft. CONSTITUTION:When a driving shaft 1 is rotated by a motor or the like, an inner race 9 of a first angular ball bearing rotates to rotate a ball 11 clamped between the inner race 9 and an outer race 10 by a set pressure of a spring 29 to revolve a first output shaft 12 retaining the ball 11. The first output shaft rotates an inner race 20 of a second angular contact ball bearing, and a second output shaft 23 is revolved due to the rotation of a ball 22. That is, the rotational speed of a transmission shaft 27 integral with the second output shaft is a rotational speed having speed ratio in which the product of a first stage speed down ratio and a second stage speed down ratio is made a speed down ratio. By providing in multistage the speed reduction shafts, that is, speed change mechanisms, a high reduction ratio can be obtained.
