A GAS DRIVEN ROTATION MOTOR, A TOOL PROVIDED WITH A GAS DRIVEN ROTATION MOTOR AND A METHOD FOR REGULATING THE ROTATION SPEED OF A GAS DRIVEN ROTATION MOTOR |
摘要 |
<p>A gas driven motor includes a housing, a gas driven rotating member including a rotor and a rotor shaft carrying the rotor and journalled in a first bearing and a second bearing supported in the housing, and a speed governor for controlling a pressure gas inlet flow in response to the rotation speed of the rotating member. The first bearing includes a set of rolling elements, an outer race arranged in the housing and an inner race arranged on a shaft portion of the rotating member, the set of rolling elements being in contact with the races on which the rolling elements roll. The motor further includes a coupling device arranged to couple the speed governor to the rolling elements of the first bearing, thereby transferring the rotary motion from the rolling elements to the speed governor.</p> |
