Abstract

A powered rotary knife includes a handle, a blade housing, an annular blade, and a blade bushing for rotatably mounting the blade within the housing. The blade housing includes an inner groove that is operable to receive the blade bushing therein. The blade housing and blade bushing are split in order to expand and receive the blade. The blade includes an outer groove that is also operable to receive the blade bushing. Thus, the blade bushing is spaced between the blade housing and blade and rotatably secures the blade within the blade housing.

Description

technical field

[0001] The present invention relates primarily to powered knives, such as those commonly used in meat processing in slaughterhouses. More particularly, the present invention relates to a rotary cutter with a rotating annular blade and an annular bush supporting the blade. Background technique

[0002] In the meat processing industry, the use of powered knives for the handling of animal carcasses is well known in the art. The process of carcasses usually involves removing the meat and fat from the various bones and cutting the various bones. Powered tools allow workers to complete the process more efficiently than traditional non-powered tools. In the prior art powered tools are rotary tools with rotating annular blades. Many rotary knives are electrically driven and can rotate the annular blade at very high angular velocities.

[0003] Rotary knives are problematic and have limitations. For example, the high speed rotational motion of the ring blades, id...
