International Classification:

E01C 19/38

US Classification:

404117, 404122, 74 61

Abstract:

Apparatus for transferring a linear load through a high-speed rotating member includes a linear actuator containing an axially translatable cylinder rod. A mounting adapter fixed against axial and rotary movement is rigidly affixed to an actuator cylinder containing the cylinder rod. An elongate guide sleeve, fixed to the mounting adapter, extends axially from the adapter to accommodate an axially translatable thrust bearing affixed to one end of the cylinder rod. The guide sleeve contains a linear slot for accommodating a guide pin affixed to the thrust bearing housing, and transversely movable within the linear slot to prevent rotation of both bearing housing and cylinder rod components.

International Classification:

E01C 19/28
E01C 19/26
E02D 3/074

Abstract:

A construction vehicle includes a frame, at least one drum, and a vibratory system. The vibratory system includes a first eccentric weight, a second eccentric weight, and a shift assembly adapted to vary an amplitude of the vibratory system. The shift assembly includes a shaft member adapted to move along a first axis for changing a position of the first eccentric weight relative to the second eccentric weight. The shift assembly also includes an actuator and a fork assembly adapted to move the shaft member along the first axis. The fork assembly includes a fork fixedly coupled to the actuator. The fork assembly also includes a housing member concentrically disposed around the shaft member, wherein the fork is pivotally coupled to the housing member at a pair of pivot points defined proximate to the second end of the fork. The fork assembly further includes a bearing member.

Abstract:

A vibratory system for a compactor machine, the vibratory system optionally including a key shaft, an input shaft, a first output shaft and a second output shaft. The key shaft can have a first internal helically splined portion and a second internal helically splined portion. The first internal helically splined portion can be oppositely splined with respect to the second internal helically splined portion and arranged axially of the second internal helically splined portion. The input shaft can be configured with an external helically splined portion configured to be complimentary to the first internal helically splined portion of the key shaft. The first output shaft can be configured couple to the input shaft for rotation therewith. The second output shaft can have an external helically splined portion configured to be complimentary to the second internal helically splined portion of the key shaft.
