Abstract

See full text

A pneumatic tool motor includes a cylinder, a rotor set, an output shaft and an internal hammering device received in a roller cylinder of the rotor set. A front cover and a rear cover respectively mounted on two opposite ends of the roller cylinder, wherein a front bearing and a rear bearing are respectively disposed in the front cover and the rear cover. The roller cylinder has two opposite ends respectively connected to the first bearing and the second bearing and the two opposite ends of the roller cylinder respectively abut against the front cover and the rear cover. Consequently, the roller cylinder does not needs to form any terminal structures on its two opposite ends for simplifying structure, reducing manufacturing cost and narrowing volume.
