<P>PROBLEM TO BE SOLVED: To provide a structure on an inner surface of a tube which considerably improves heat transfer when a medium flowing on the inner surface of the tube is evaporated while preventing an excessive increase in a pressure drop; further, to meet a condition that the structure should be securely manufactured at low cost. <P>SOLUTION: A measured twist angle of an inner fin is smaller than or equal to 45 degrees relatively to a tube axial line. Regions of the inner fins separated from a tube wall are formed to be asymmetrical substantially in the tube circumferential direction at regular intervals on one side. Molded material of the inner fins forms projection parts at upper parts of grooves. The projection parts are respectively extending over limited molding zones along one inner fin, and a degree of molding continuously changes inside the molding zones. Molding parts are cut out more strongly at center parts of the molding zones than at the edges. The heat transfer tube includes hollow spaces for making formation of bubbles desirable among groove bottoms, side parts of the inner fins, and the formed projection parts. <P>COPYRIGHT: (C)2010,JPO&INPIT
48 Nut JP23557595 1995-09-13 JPH0893742A 1996-04-09 EBUARUTO BEHIRE
PROBLEM TO BE SOLVED: To prevent a nut from being spontaneously loosened even if a preload is eliminated due to excessive times of use by reducing a wall thickness of a clamp tongue piece as it departs from a drive part in an axial clamp area of a nut. SOLUTION: A drive part 2 forming a polygonal shape of a nut extends to a contact surface 4 on an axial lower side of the nut. A clamp area 3 is formed of a slot 8 and a clamp tongue piece 15. The wall thickness of the clamp tongue piece 15 is formed thinner than a portion in proximity to the drive part in its free end part. Namely, an outer peripheral surface 7 is not extended in parallel with an inner peripheral surface having female threads 12, but an angle is formed between the outer peripheral surface 7 and the inner peripheral surface, and the tip of a cone having this angle is faced in the direction apart from a tongue side surface 4. Thus, inside the clamp tongue piece 15, an expansion distribution is improved and a balanced surface pressure between nuts and the bolts acting in association with the nuts can be obtained over the entire length of the threads, and seizure between the threads can be avoided.
49 Nut, in particular wheel nut JP8983993 1993-04-16 JPH0610936A 1994-01-21 EEBUARUTO BEHIRE
PURPOSE: To improve a contact condition between a member, to which a nut is tightened, and a pressure washer, thereby to provide a uniform distribution of a contact pressure by manufacturing the pressure washer through the massive forming method so as to give a concave contact zone. CONSTITUTION: This nut is an integrally formed pressure washer having a concave contact surface 4a. In this case, the pressure washer is manufactured by the massive forming method. When the nut is tightened, it is necessary to reduce the axial clearance between the pressure washer and the corresponding surface from the start of the contact of the outside diameter of the pressure washer until the complete contact of the pressure washer. Therefore, uneven tightening force is compensated by elastic deformation of the pressure washer caused by further tightening of the pressure washer.

The internal thread-rolling tool employs evenly spaced rim rollers which turn round their axes relative to the revolving body through an angle equal to the thread lead angle. The body also contains grooving rollers (6,7,8) cutting at the same angle as the thread rollers (3,4,5) and with the same spatial relation to the axis round which the body rotates (1), but turned at an angle to the thread rollers. - The thread vertices of the grooving roller are axially offset from those of the directly preceding thread forming roller as projected onto a plane normal to the body axis by an amount P/2-P.Beta/360 deg., where P is the thread pitch being generated and BETA is the angle between the rotation axes of the grooving and preceding thread forming roller projected onto the plane specified. Thus the grooving rollers enter the blank first and act as cams guiding the vertices of the thread forming rollers following on behind.(1,2)

53 Inside diameter thread rolling device JP7772881 1981-05-22 JPS57193256A 1982-11-27 AIHARA HIDEO
PURPOSE:To cut a thread by one go and return motion without performing a cutting work, to shorten the working time, and to elevate strength of the thread, by cutting the thread by rotation of a main shaft, and forming the thread again by its returning. CONSTITUTION:This device is used by installing it to a machine which is capable of feeding one pitch portion of a thread of a thread-cut working product 10 when a planet roller receiving bushing 3 has made one rotation, by rotating a main shaft 5 and fixing the working product 10, or fixing the main shaft 5 and rotating the working product. The ratio of the diameter of a main roller 1 and a planet roller 2 is set to 2:1. As for the diameter, the main roller 1 and the planet roller 2 are set to the diameter by which a crest circumscribed circle of 4 planet rollers 2 adheres tightly to the thread crest inside diameter of the working product whose thread has been cut, from the center of the main roller 1 whose crest is engaged, is made to adhere and is rotated.

A method for the production of threads, especially internal threads, by means of a rotationally driven thread former, with which the thread pitches are driven in and out of the surface of the workpiece in a chipless fashion by pressure forming, in particular in and out of the inner surface of a workpiece bore. In order to be able to produce threads of different nominal diameter especially economically and with improved joining quality in the area of the thread, the thread is formed such that a shank tool in the fashion of a thread miller, equipped with at least one profile projection, preferably two profile projections located at a constant distance from one another, where the profile projections at its forming head are constructed as continuous over the circumference and with radial extension varying over the circumference, is driven into the workpiece initially at a circumferential point of the workpiece bore, preferably is brought to the total thread pressing depth, and while substantially retaining the eccentricity set with respect to the axis of the workpiece bore, executes a relative circular movement running through 360° (circular movement) relative to the axis of the tool bore, while the forming head simultaneously executes a constant axial relative feed movement by the extent of the thread pitch to be produced.
59 Method for the production of a spindle nut of a spherical thread drive mechanism US11053578 2005-02-08 US20050204562A1 2005-09-22 Jurgen Osterlanger; Manfred Kraus; Torsten Keller; Thomas Motz
Method for the production of a spindle nut (3) of a spherical thread drive mechanism, whereby the spindle nut (3) has at least one screw-shaped track (4) formed as a single piece on its inner circumference, whose threads (38) are limited by shoulders (6). The shoulder (6) is interrupted by a deflecting recess (23) at at least one deflecting position, in order to deflect balls (13) out of one thread into an adjacent thread (38). The method includes locating a tool arbor (56) in a hollow blank (57), whereby the tool arbor (56) has on its outer circumference a counter profile of the screw-shaped track (4) and a projecting part (59) for each deflecting recess. A tool operates on and reshapes the blank (57) from the exterior by exercising radial forces (F), whereby during the reshaping process the inner circumferential surface of the blank (57) is shaped according to the counter profile and to the projecting part (59) of the tool arbor (56) such that the screw-shaped track (4) and the deflecting recess (23) are formed.
60 Method of manufacturing ball joint US09979803 2001-11-27 US06591657B1 2003-07-15 Hiroshi Kato
An intermediate molding (41) is formed so that a cylindrical arm-to-be portion (42) projects from the cylindrical outer surface of a body portion (13) of the arm-to-be portion (42). The arm-to-be portion (42) has a given thickness and a hole (42a) with a diameter greater than the inner diameter of a projecting connector portion (20) of an arm portion (15). A pair of flat face portions (42b) extending parallel to the axis of the body portion (13) are formed on the cylindrical outer surface of the arm-to-be portion (42). A tap (44) that has an external thread (43) formed along its cylindrical outer surface is inserted into the hole (42a) of the arm-to-be portion (42). Concave faces (49),(49) are concaves respectively formed on the opposing surfaces of an upper die (47) and a lower die (48) so as to have a shape like a half cylinder with a curvature corresponding to that of the cylindrical outer surface of the projecting connector portion (20). The concave faces (49),(49) sandwich and apply pressure to the arm-to-be portion (42), thereby narrowing the arm-to-be portion (42) and forming an internal thread (19) in the cylindrical outer surface of the hole (42a) of the arm-to-be portion (42). With the tap (44) being removed while being rotated, formation of the arm portion (15) is completed. Compared with a method that calls for forming an internal thread (19) by threading with an external thread (43) of the tap (44), the method of the invention enables the easier and quicker formation. The invention also prevents wear of the tap (44) and enables the easy formation of the projecting connector portion (20) of the arm portion (15) having stable characteristics and a desired internal thread (19).
