| The invention relates to the production of screw pump rotors comprising a pitch and/or depth of teeth which can be modified along the axis of the rotor. By means of a simple profiled machine tool (7), a first part of the profiled flank contour is clearly defined along the rotor axis (8) by means of its specific tool guide mechanism, and is then produced in a definitive manner. The remaining second part of the profiled flank contour is then determined according to the rolling movement of the pair of rotors according to the first part of the profiled flank contour carried out by the tool, by means of an approximation which is as precise as possible. It is thus possible to obtain transversally different profiled contours according to the pitch and/or depth of teeth which can be modified along the axis of the rotor. A disk milling cutter is selected to be used as a profiled machine tool. | ||||||

| PURPOSE: To machine a scroll component at high speed and that in a highly accurate manner, by keeping moving paths of a tool constant in rectilinear form when the scroll component being used for a compressor of a refrigerator or the like is machined, and synchronizing the tool movement with rotation of the component mechanically. CONSTITUTION: When the outside of a wall 2 of a scroll component 1 is machined, an outer wall surface 14 is of an involute curve, and a tool 3 in use is, for example, an end mill. And, a turning center of this tool 3 is designed to be shiftable on a tangent (d) line offsetting a radius portion of a base circle of the involute curve. In addition, the scroll component 1 is set up to be rotatable with a center (a) point of the base circle as the center. These movements are carried out by a numerically controlled machine tool. Rectilinear motion in an arrow direction of the tool 3 and rotational motion of the component 1 come to simple proportion, and it is offset as far as the radius portion of the tool 3 in the arrow direction from the involute curve of the outer wall surface 14, whereby if movement of the tool 3 and rotation of the component 1 are carried out, the outer wall surface 14 is machinable. In this connection, an inner wall surface 16 is also machinable. COPYRIGHT: (C)1987,JPO&Japio | ||||||

| PURPOSE:To lower the friction coefficient of a contact surface and reduce power loss, by forming mesh-like recesses and projections on the contact surface of the tooth form of a trochoid type hydraulic motor or pump, and covering this contact surface with a chemically processed coating of which thickness is lower than the height of the recesses and the projections. CONSTITUTION:A peak A and a valley B (recesses and projections) are formed, as shown in D and E, in the axial direction and the circumferential direction of an outer tooth by grinding. The tip of the peak A is rounded by barrel finishing and shot peening, and it is covered with a phosphate coating thereafter. In this case, the thickness of the coating C is made smaller than the height of the peak A and the valley B. Here, the height of the peak A and the valley B is made preferably 1-10mu, and the thickness of the coating C is made preferably up to about 3mu a little lower than the height of the peak A and the valley B. Thus, in an abrasion condition after sliding and engaging, the tooth form remains, as shown in F and G, mesh-like in the axial direction and the circumferential direction of the outer tooth, lubricating oil working also as operational oil is sufficiently retained in every position of the contact surface, so that the friction coefficient of the contact surface can be reduced. | ||||||

| PURPOSE: To simplify a controlling method while improve machining accuracy by making the feeding direction of a moving table agree with the tangential direction of the base circle of an involute, while making a feed speed proportionate to the rotating speed of a rotary table. CONSTITUTION: An X-axis table 10 is straightly advanced in such a way that the center Q of an end mill 7 is moved in the inner direction on a tangent line 21, while rotating a rotary table 12 with its rotation angle being interlocked with the feed of the table 10 in a certain proportional relation, to machine the outer wall of an involute curve 5a. After machining is over, the table 12 is reversed, a male scroll 1 is also reversed and the phase of the rotation angle is shifted by a certain amount, and the end mill 7 is positioned in the start position of an involute curve 5b. And, synchronized with the reverse rotation of the table 12, the table 10 is straightly advanced in the returning direction so as to move the center Q of the end mill 7 in the outer direction on the tangential line 21, to machine the inner wall of the involute curve 5b. Accordingly, any correction of error by means of the angle of deviation θ" is not necessary also for the inner wall of the curve 5b. COPYRIGHT: (C)1987,JPO&Japio | ||||||

| PURPOSE:To permit to work the internal wall surface of the scroll into a predetermined dimension and improve the sealing property upon meshing as well as the performance of the scroll by a method wherein the outer peripheral end of the scroll body is worked under a condition that the outer peripheral end is extended to an extent longer than the same end upon finishing and the extended section is cut off after finishing the working of internal wall surface. CONSTITUTION:The outer peripheral end 80 of the scroll body 282, 302 is extended than the same end 41 upon finishing the working thereof. Under this condition, the internal wall surface 50 is cut sequentially from the internal wall surface 50 of the outer peripheral end 41 toward the center of the scroll by a cutting tool such as a mill cutter or the like, thereafter, the outer wall surface 60 is cut. Then, unnecessary section of the extended section 80 is cut off by an end mill cutter or the like to obtain a predetermined finishing dimension. Thus, the internal wall surface 50 is worked under a condition that the rigidity of the outer peripheral end 41 upon finishing is reinforced, therefore, the tilting of the upper part of outer peripheral end 41 may be reduced and the upper part of internal wall surface 50 of the same peripheral end 41 may be worked into the predetermined finishing dimension. Accordingly, the sealing property upon meshing of the scroll members 28, 30 may be improved and the performance of the hydraulic machine may be improved. | ||||||

| PURPOSE: To obtain a scroll member made by combining a volute body and a side plate in a body inexpensively and simply by rolling a preparatory volute body of a scrool member for a scroll type fluid machine between two specified rotary volute bodies for working. CONSTITUTION: A working apparatus 30 consists of the first volute body for working 312, a side plate member 31 having through-holes 313, the second volute body for working 32 of the same volute direction provided with driving pins 321 and a rotary driving plate 33 having fitting holes 331. A preparatory scroll member A formed as accurately as cost permits is fixed on a working stand 34 and the volute body is inserted into a clearance between inner and outer walls of volute bodies 312, 32. When a plate 33 is rotated in the direction B, the volute body 32 is rotated through-pins 321 fitted to the holes 331. When the member 31 is rotated in the direction C, which is reverse to B, the volute body 312 is rotated. At this time, movement of pins 321 is restricted by holes 313 inner sides of which are made to concentric arcs around the center of the volute body 321. The clearance of above-mentioned walls is narrowed and the volute body of the member A is finished at uniform accuracy. COPYRIGHT: (C)1982,JPO&Japio | ||||||
