摘要： A castor wheel assembly comprises a tubular casing of rectangular cross section extending in axial direction between a pair of opposed ends and a swivel member for connecting the casing to an object supported thereon for relative rotation about a vertical swivel axis. A shaft extends horizontally through the casing for connection to pivot arms at opposed ends thereof. A castor wheel is coupled between the pivot arms spaced radially outwardly from the shaft. A flange spans radially from the shaft a fully width of the casing along a length of the shaft. Elastomeric material supports the shaft and the flange along one wall of the casing such that the elastomeric material is arranged to be compressed between the flange and an opposing wall of the casing by rotation of the shaft resulting from upward deflection of the wheel relative to the casing.

摘要： Disclosed is a brake caster with stroke adjustment mechanism, including a retainer, a king pin, a catch spring, a catch/release button, a plunger block, and a brake pad. The upper part of the king pin is fitted with the spring coil; the catch/release button is fitted with the catch spring; and a threaded polygonal lock nut is placed over the catch/release button in the hollow space of the plunger block, which has the brake pad installed on the bottom end; the plunger block being coupled with the catch/release button is slipped onto the king pin lengthwise along the threads. By twisting the plunger block in and out around the neck of the plunger block, the stroke distance can be adjusted according to different levels of rubber on the wheel, so that the service life of the caster can be effectively prolonged without numerous replacements of the wheels.

摘要： A caster has two spaced apart wheels with an elastomeric torsional shock and vibration isolating suspension between them. The wheel axis is spaced longitudinally from a bearing axis to subject elastomeric disks positioned between the wheels to torsional shear stresses to help absorb shocks and vibrations. A snubber is provided for limiting the angular motion of the wheels about a bearing axis.

摘要： An undercarriage system apparatus is provided for supporting and transporting a fluidized patient support system above and across a floor. The apparpatus includes a base frame for carrying the fluidized patient support system, a plurality of heavy duty casters, and a pair of disk springs disposed between each caster and the base frame. Each caster includes a central shaft, a shoulder portion disposed about the central shaft for carrying the load, a wheel carriage rotatably mounted via needle bearings to swivel about the central shaft, and a pair of caster wheels mounted side-by-side to rotate about the wheel carriage. The disk springs of each pair are disposed to contact at their outermost edges. Each dish spring desirably has a maximum load capacity rated at least 50% above the nominal load which the disk spring must carry. The base frame defines a sleeve for receiving each central shaft of each caster. An elongated slot is defined through each sleeve. A threaded opening extends radially into the central shaft of each caster about 1 inch above the shoulder. A bolt screws into the threaded opening and rides within the confines of the slot of the sleeve as the disk springs are compressed and uncompressed during shock absorbing events.

摘要： A roller for a bearing used in a linear movement rolling guide apparatus is tumbled after superfinishing the outer peripheral surface so that the surface roughness of the roller in a circumferential direction is in a range from 0.05 to 0.10 micrometers in average roughness on the center line. The surface roughness in the circumferential direction of the outer peripheral surface of the roller is substantially equal to or slightly larger than the surface roughness in the axial direction of the outer peripheral surface to thereby prevent the occurrence of micro-slip.

摘要： A steering roller arrangement for a trackless floor vehicle in the form of a so-called three-wheeled vehicle is described. With this vehicle, in addition to two running wheels, a steering roller is provided which can be swiveled about a vertical axis by means of a ring mount for traveling in a curved line and to achieve a trailing effect. Relative to the rotatable part of the ring mount, the steering roller is movable between two opposite trailing positions such that, with a reversal of the direction of travel, the required alteration of the steering roller trailing effect is brought about by a corresponding adjustment of the steering roller. In this way uncontrolled veering of the vehicle is avoided which occur with conventional three-wheeled vehicles on account of the rotation of the steering roller by 180.degree. caused by the trailing effect of the steering roller. The steering roller is expediently displaceable in a straight line by a linear guide between the two trailing positions. The linear guide can serve at the same time as a self-aligning bearing, by mans of which the steering roller can be tilted about a horizontal axis to adapt to unevenness in the floor.
摘要翻译：描述了所谓三轮车形式的无轨地板车辆的转向辊装置。对于该车辆，除了两个行驶车轮之外，还设有转向辊，该转向辊可以通过环形支架绕垂直轴线旋转，以便以曲线行进并实现拖尾效果。相对于环形安装件的可旋转部分，转向辊可以在两个相对的后退位置之间移动，使得随着行进方向的反转，转向辊拖尾效应的所需改变是通过相应的转向辊。以这种方式避免了由于转向辊的拖尾效应引起的转向辊旋转180°而导致的传统三轮车辆发生的不受控制的车辆转向。转向辊通过两个拖尾位置之间的直线导轨在一条直线上方便地移动。直线导轨可以与自调心轴承同时工作，其中转向辊可以围绕水平轴线倾斜以适应地板的不平坦。

摘要： In accordance with this invention I provide a curb laying machine designed to extrude curbing of molten asphalt or concrete in a parking lot or the like. This machine utilizes a wheeled chassis, and a curb mold removably carried on a lower portion of the chassis, with the lower edges of the mold in contact with the ground during the laying of curbing. An engine driven auger is utilized for bringing about the extrusion of curbing through the curb mold as the machine moves slowly forward. My machine utilizes a chassis, steerable front wheels supporting a forward portion of the chassis, and first and second rear wheels mounted on a rearward portion of the chassis. The improvement in accordance with my invention comprises a rapidly operable height changing mechanism associated with the first rear wheel, latter wheel being located in the immediate vicinity of the curb mold. This first wheel is disposed upon a pivoted framework mounted on a lower portion of the chassis, and also provided is an extensible fluidic actuator under control of the operator of the machine. This extensible fluidic actuator is operatively connected to the pivoted framework, and serving, when caused by the machine operator to extend, to rapidly bring about a degree of lifting of the rear portion of the chassis, thus to remove the lower edges of the curb mold from ground contact, and thereby enabling the operator to turn or move the machine to a new operative position.
