| 摘要 |
The present invention relates to a new structure of a decelerator which allows an operator to quickly confirm the rotating speed of an output shaft and to precisely control the rotating speed of the output shaft. The decelerator according to the present invention includes a rotation speed detection sensor (60) which is coupled to the output shaft (30) and measures the rotating speed of the output shaft (30), and a display device (70) which is installed on one side of a housing (10), receives signals from the rotation speed detection sensor (60), and displays the rotating speed of the output shaft (30) measured by the rotation speed detection sensor (60), thereby allowing the operator to quickly and precisely confirm the rotating speed of the output shaft (30). |
