Embodiment Construction

[0014] Referring to FIG. 1, there is shown a side cross-sectional view of an impact machine 10 including a cage member 100 in accordance with a preferred embodiment of the present invention. The impact machine includes a motor 12 having an output shaft 14 with a splined end 16 configured to engage a cage member 100 to rotate the cage member 100 .

[0015] Cage member 100 is generally formed in the shape of a hollow bracket having an anvil end plate 102 and a splined end plate 104 joined by a pair of diametrically opposed supports 106 and 108 . The splined end plate 104 adjacent to the motor 12 includes a corresponding splined connection 110 for engagement with the splined end 16 of the output shaft 14 of the motor 12 .

[0016] The cage member 100 journals the PTO shaft or anvil 20 in a cage member bore 112 made in the spline slot end plate 104 adjacent the spline slot connection 110 . The cage member 100 itself is journalled on the anvil 20 at a location 22 . Also, inside t...

Abstract

An impact mechanism having a rotating cage member that supports at least one hammer for imparting impacts upon an anvil. More particularly the present invention relates to a cage member of an impact mechanism wherein each hammer pin is supported in a partial bore hole in the end of the cage member closest to the motor of the impact mechanism.

Description

technical field [0001] The present invention relates generally to impact machines and, more particularly, to pneumatic impact machines having improved cage member strength characteristics. Background technique [0002] Impact machines such as pneumatic impact heads and the like are well known in the prior art. One such device is disclosed in US Patent No. 3,661,217 to Maurer, which is incorporated herein by reference. Such prior art impact machines typically include a motor having an output shaft that rotates the cage member. The cage member journals the power take-off shaft or anvil within the bore of the cage member. The anvil includes single or double cams, depending on the number of hammers or stops. Each hammer is pivotally connected to the cage member by an axial hammer pin such that the hammer can swing relative to the cage member and rotate with the cage member. As the cage member rotates, the hollow inner side of the hammer engages the cam to engage the anvil an...
