Abstract:
To retain a separation cage of a mechanical roller bearing in an annular roller bearing space.SOLUTION: An output shaft 2 of a speed reducer is fitted rotatably on a lengthwise axis 22 inside a speed reducer casing with a mechanical roller bearing 6 supported by a bearing provided to the speed reducer casing between a tangent wheel 23 and a pinion 24. The mechanical roller bearing has a plurality of rolling bodies retained by a separation cage 65 mutually at a distance, the rolling bodies and separation cage are arranged in an annular roller bearing space 63 formed between an inner ring 61 and an outer ring 62 which are concentric, and the separation cage can be released in one release direction 654 from the annular roller bearing space. An assist module includes a block element 32 having stop surfaces 33 facing the annular roller bearing space, and one stop surface is positioned at such a distance that the separation cage is stopped from being released from the annular roller bearing space.SELECTED DRAWING: Figure 3
