摘要： A gear grinding machine uses a grindstone tool, having an outer circumference that includes a thread, to grind a tooth surface of a gear workpiece. In this case, coolant is supplied toward the tooth surface from a trailing side in a rotation direction of the gear workpiece through a space between the grindstone tool and the gear workpiece. The coolant is drawn into the meshing portion between the grindstone tool and the gear workpiece by the rotation of the gear workpiece and the movement of the thread of the grinding tool.

摘要： A grinding device for raised joints of rivets on sheet metal is provided, including a lateral plate, legs, a moving plate, first springs, a first bearing seat, a sleeve, a grinding wheel, a moving bar, a 7-shaped plate, a vertical bar, a second spring, an oscillating plate, etc. The legs are fixedly connected, in a symmetric manner, to left and right sides of the bottom of the lateral plate. A through hole, which has a function of guiding, is formed on a left side of the lateral plate. The moving bar is located in the through hole. In the present disclosure, a driving motor is started to rotate the grinding wheel, the grinding device is moved to enable the grinding wheel to be located above a raised joint, and then the oscillating plate is pulled so that the grinding wheel can move downward to grind the raised joint.

摘要： A method of repairing a defect in a damaged rail of a railroad track comprises positioning a rail profiling device on the rails of the railroad track proximate a defect; securing the rail profiling device to the railroad; adjusting its grinder according to a selected value of wheel cone angle to create a profiled running surface over a portion of the damaged rail; creating a median zone using the grinder to remove material from the damaged rail adjacent the defect at a depth corresponding to at least a maximum depth of the defect; creating an incline from the top of the rail and leading to the median zone and one incline leaving the median zone to the top of the rail by using the grinder to grinding material off the damaged rail.

摘要： A system and a method for sawing control joints in concrete barriers is provided. The system includes a barrier mounting frame slidably mountable about the barrier, on the top, first and second lateral faces of the barrier. The system also includes a saw attachment having a circular saw attached thereto, the circular saw being manually operable. A linkage assembly connects the frame mounting barrier to the saw attachment, and allows to manually move the circular saw up or down, and towards or away from the barrier, when in use, to create the control joint transversally along the top, first and second lateral faces of the barrier.

摘要： A method of making a longitudinal reinforcing structure for a wind turbine blade. The method comprises a) providing an elongate master strip (62) of reinforcing material having substantially flat first and second surfaces, the distance between the first and second surfaces defining the thickness of the master strip; and b) dividing the master strip transversely to form a first strip and a shorter master strip, the respective strips being arranged end to end such that a trailing end of the first strip is located adjacent a new leading end of the master strip. The step of dividing the master strip comprises removing material from a dividing region extending through the entire thickness of the master strip, wherein the dividing region is shaped such that a chamfer (19c) at the trailing end (19b) of the first strip is created and a chamfer (63a) at the new leading end (63) of the master strip is created when the master strip is divided.

摘要： A single station shaper sander that uses a quick change retractable shaper and a quick change retractable profile sander is described. The shaper generates a profile in a substrate, and then the sander sands the profile in the substrate without intermediate removal of the substrate. Both the shaper and sander are retractable, moving away from the substrate when retracted, and are moved into contact with the substrate when engaged. Either an operator or automatic controls may be used to engage and retract the shaper or sander, so as to minimize operator access to dangerous moving surfaces on either. Further, each sander or shaper may have removable tools that are temporarily affixed to a spindle, affording tool changes of 15 seconds or less.
