Description

one

The invention relates to mechanical engineering, in particular to pneumatic machines with a rotary engine.

Pneumatic hand-held machines containing a pneumatic motor located in the housing and secured therein with a threaded nut, an actuator, the housing of which has an iniary base surface coupled to the base surface of the engine housing, and fastening screws connecting both housings fll.

The lack of such machines is the difficulty of making a threaded pair of fastening the power adapter, the absence of connecting channels between the Kopiyca chambers of the engine exhaust air through the body of the actuator, the lack of reliability of the threaded holes in the motor housing under the clamp screws.

Pneumatic hand-held machines are also known, which contain an air motor installed in a housing, the base surface of which is associated with the cylindrical base surface and the operating mechanism, and fastening screws, both of which are

corps, as well as channels, soyiin yuishe ko}. engine and executive engine gear;) ma 2 ..

In this mask, the air motor housing is not reliably connected to the housing of the test mechanism.

In order to improve the reliability of soezhniki housings and simplos technology of sabozh, in the proposed method, a ring was installed between the two housings, which had located around the circumference of the casing with the threaded holes, the fastening screws, and between the ring and the pneumatic engine, the retaining elements were set with fixing screws. the air motor bodies are made with an angular tag, a multiple of the ring hole pitch, BI.IO are blunt with the holes for the fastening screws.

The locking elements can be made in the type of screws installed in the threaded holes of the ring or elastic oetals.
