Rotary engine rotor

摘要

A rotary engine rotor (10) comprises a body (12) comprising an outer surface (18), an inner surface (22), an insert (14) and a fixing member (16). The outer surface (18) comprises three rotor sides (20) arranged in an equilateral triangle shape. The inner surface (22) comprises a location portion (24) at the midpoint of each rotor side (20), the location portions (24) together defining a location aperture (26). One location portion (24) is provided with a first fixing socket (28) extending radially from the inner surface (22) of the body (12), towards the outer surface (18) of the body (12). Cooling channels (30) are provided axially through the body (12) in the region of each apex (31). The insert (14) is provided in the location aperture (26) and comprises a bearing part (38) with a second fixing socket (40) extending radially through the insert (14) and in alignment with the first fixing socket (28). The fixing member (16) is provided through the second fixing socket (40) and received in the first fixing socket (28) to couple the insert (14) to the body (12).

1. A rotary engine rotor comprising:
a body comprising:
an outer surface comprising three radially spaced rotor sides that meet at three radially spaced apexes, so that the radially spaced rotor sides are arranged in a generally equilateral triangle shape; andan inner surface comprising:
a respective location portion provided generally at the midpoint of each rotor side, the location portions together defining at least in part a location aperture and one location portion being provided with a first fixing socket extending generally radially from the inner surface of the body, away from any of the apexes, and only part way towards the outer surface of the body in such a way that the first fixing socket does not impinge on the outer surface; and a cooling channel provided axially through the body in the region of each apex;an insert provided in the location aperture and comprising a bearing part and an indexing gear, the bearing part being provided with a second fixing socket extending generally radially through the insert and provided in alignment with the first fixing socket; anda rigid elongate fixing member provided through the second fixing socket and at least partially received in the first fixing socket to thereby couple the insert to the body.
