Abstract

An impeller for a centrifugal blast wheel machine includes a hub provided at one end of the impeller, with the hub being configured to be coupled to the motor. The impeller further includes a tapered section provided at an opposite end of the hub, with the tapered section defining a media inlet to receive blast media. The impeller further includes a plurality of drop-shaped vanes positioned between the hub and the tapered section. The plurality of drop-shaped vanes is spaced from one another on peripheries of the hub and the tapered section. The plurality of drop-shaped vanes defines a plurality of impeller media outlets constructed and arranged to allow egress of blast media upon rotation of the impeller. Each vane is drop-shaped having a leading side directed toward a direction of rotation of the impeller and a trailing side opposite the leading side.

Abstract

A centrifugal blast wheel machine comprises a housing and a wheel assembly coupled to the housing. The wheel assembly has a plurality of blades configured to throw blast media introduced into the wheel assembly against a work piece. According to one embodiment, each blade of the plurality of blades includes a curved portion positioned adjacent a central hub of the wheel assembly, and a straight portion integrally formed with the curved portion extending radially outwardly from the wheel assembly. According to another embodiment, each blade includes a first side rail extending along the blade, the first side rail having a first recess, and a first grommet positioned in the first recess.

Abstract

A spring assembly (80) positions a liner (56) with respect to a housing (12) of a centrifugal blast wheel machine (10). The spring assembly (80) is mounted on a front wall (50) of the housing (12) and configured to exert a spring force against the liner (56) to push the end liner (56) against side wall liners (58, 62). The spring assembly (80) includes a spring base plate (82) attached to the front wall (50) of the housing (12), at least one spring (92) configured to engage the spring base plate (82), a spring bracket (104) configured to secure the spring (92) in place with respect to the spring base plate (82), and at least one fastener (84) to secure the spring bracket (104) to the spring base plate (82). The spring (92) is disposed between the spring base plate (82) and the spring bracket (104).

Abstract

A centrifugal blast wheel machine includes a wheel assembly having blades configured to throw blast media introduced into the wheel assembly against a work piece. An impeller driven by a motor is positioned about an axis of the wheel assembly. The impeller has a media inlet at one end adapted to receive blast media and a plurality of impeller media outlets constructed and arranged to allow egress of blast media upon rotation of the impeller. A control cage surrounds the impeller and is secured to the wheel assembly. The control cage includes a cylindrical body defining an interior chamber. The cylindrical body has an opening formed therein to allow the egress of blast media from the interior chamber. A timing of the impeller is advanced in relation to a corresponding blade to achieve a considerable effect on both the distribution and intensity of a blast wheel blast pattern.
