摘要： A rock cutting tool with a plurality of independently rotatable cutter units and with a shaft, a sleeve located around the shaft, and at least two rotatable hubs located around the sleeve. At least one cutter unit is located on each of the two rotatable hubs for rotation about an axis of rotation with respect to a rock-face. Bearings between the sleeve and each of the hubs rotatably support the hubs. The bearings comprise at least one cylindrical roller bearing set and at least one ball bearing set for each hub. Each roller bearing set is located substantially entirely under the cutter unit of its associated hub to absorb radial loads, and each ball bearing set is located remotely from the cutter unit of its associated hub to be isolated from radial loads. The shaft has first and second key receiving openings. The key is located on the interior surface of the sleeve. The key is mateable with the first and second key receiving openings in the shaft whereby the sleeve is rotatable with respect to the shaft from a first position to a second position to disengage the key from the first key receiving opening and engage the key in a second key receiving opening to extend the bearing life.
摘要翻译：一种具有多个可独立旋转的切割器单元并且具有轴，位于轴周围的套筒以及位于套筒周围的至少两个可旋转毂的岩石切割工具。至少一个切割器单元位于两个可旋转轮毂中的每一个上，用于围绕相对于摇滚面的旋转轴线旋转。套筒和每个轮毂之间的轴承可旋转地支撑轮毂。轴承包括至少一个圆柱滚子轴承组和至少一个用于每个毂的球轴承组。每个滚子轴承组件基本上完全位于其相关联的毂的切割器单元下方以吸收径向载荷，并且每个滚珠轴承组远离其相关联的轮毂的切割器单元定位成与径向载荷隔离。轴具有第一和第二键接收开口。钥匙位于套筒的内表面上。所述钥匙可与所述轴中的所述第一和第二钥匙接收开口相配合，由此所述套筒可相对于所述轴从第一位置转动到第二位置，以使所述钥匙与所述第一钥匙接收开口脱离接合，钥匙接收开口延长轴承寿命。

摘要： Drive head apparatus for driving the drill string of a rock boring machine, such apparatus comprising one or two drill string connectors (28) (30) having resilient means such as a coil spring (66) acting therebetween, with respective floating bearings (62) (64) separably secured thereto and with each bearing arrangement comprising respective cooperating, axially fixed bearing seating surfaces (68) (86). Each floating bearing (62) (64) is in the form of a softer metal insert replaceable on the associated connector (28) (30) without replacement of the drill string connector (28) (30). A splined cylindrical drive insert (88) rotatably drives the drill string connector and is separable from the drive body (58) in which it is seated and is axially reversible to swap wear ends or is readily replaceable without need for replacement of the entire drive body (58).

摘要： A two-piece planetary hub and output shaft for use in a planetary reduction gear drive assembly for a raise drill having a drive motor and a drive train path including first, second and third reduction gearing driving the planetary hub and output shaft. The hub and shaft are formed as two major pieces, an upper hub and a lower output shaft which are rigidly interconnected by three planet gear shafts each engaging a hole in said hub and a recess in said lower output shaft. Such interconnection is suitably by taper lock bushing assemblies locking the shafts to both said hub and said shaft. Transfer of torque occurs essentially through the planet shafts and the hub, and transfer of load occurs essentially through the output shaft.

摘要： A drill pipe has a central axis and comprises a first end and a second end with a portion of the second end being substantially triangular in the lateral cross-section and having three faces. At least one concave wrench recess is located in each of the three faces of the substantially triangular portion of the second end. Each of the recesses has a surface with an axially extending center line. The center line is located a predetermined distance from the central axis, with this predetermined distance being less than the distance from the central axis of all other axial lines on the surface of the recess.Each of the recesses may be comprised of two adjoining planes having exterior surfaces, the cross-section of the two adjoining planes forming an angle of less than 180 degrees as measured between the exterior surfaces of the two adjoining planes. Alternatively, the recesses can be comprised of three adjoining planes. Finally, the recesses may be comprised of an arcuate segment.

摘要： An inflatable gripper assembly for a rock boring or cutting machine is disclosed. The inflatable gripper assembly comprises a base member and an elastomeric sheet secured in a fluid-tight and reaction force secure manner to the base member. The elastomeric sheet expands when fluid is supplied between the base member and the elastomeric sheet to brace a rock boring or cutting machine in a tunnel. The elastomeric sheet contracts when fluid is removed from between the base member and the elastomeric sheet to allow the rock boring or cutting machine to move within the tunnel.

摘要： A down reaming apparatus has an upper stabilizer which supports the down reaming apparatus in the bored hole. A plurality of shoe assemblies are radially attached to the hub of the upper stabilizer. The shoe assemblies are biased against a bored shaft wall by pressurized cylinders which allow limited return movement with resistance of the shoe assemblies. A weight assembly comprising a plurality of stacked plates is secured to the frame of the down reaming apparatus and has manways therethrough which allow passage of workers. A lower stabilizer provides additional support for the down reaming apparatus. The lower stabilizer also includes shoe assemblies that are biased against the bored shaft wall by a pressurized cylinder.
