| PURPOSE:To simultaneously cut and chamfer a pitch groove to a required depth in bottom and shoulder parts of a caliber, by rotating a rolling roll while turning a hob cutter, forming an edge point in a predetermined tilt angle, to be advanced. CONSTITUTION:A hob cutter 34, having an edge point in a predetermined tilt angle, is set to a head 36, and the cutter 34 is moved to the center of a caliber 9 in a rolling roll 11 by a parallelly moving bed 21. And a pitch groove cutter, while turning the hob cutter 34 to be advanced with the head 36 by a right angular moving bed 26, rotates the rolling roll 11 synchronously with the hob cutter. In this way, the hob cutter 34 cuts thread-shaped pitch grooves 33 placing their right ends to rise up in the caliber 9 of the rolling roll 11 to a predetermined depth of cut by rotating the rolling roll 11 in several turns. In this way, the thread-shaped pitch groove can be correctly further promptly cut. | ||||||
| 174 | Rough machining of variable rack | JP17566183 | 1983-09-22 | JPS6067023A | 1985-04-17 | FUKUSHIMA CHIAKI |
| PURPOSE:To minimize deformation in finish machining and eliminate cutting of flow of work material by dividing teeth formed on a rack into an appropriate number of sections every approximate torsional angle and by making rough machining according to each average torsional angle of every section. CONSTITUTION:A body 5 is secured to a base 4 slid by a guide 3 and a holder 7 having a clamp 6 is provided on the body 5. And a material to be machined 11 is retained in the clamp 6 and opposed to the edge 8 of a broaching machine. To obtain a roughly machined work 1 having a center portion A with a large torsional angle theta1 and both end portions B, C with small torsional angle theta2, the clamp 6 retaining the material to be machined 11 is inclined to theta1 and the A portion is machined with the broach 8a of a first broaching machine, and inclined to theta2 and B and C portions are machined with the broach 8b of a second broaching machine arranged in parallel. After this rough machining, finish machining is made with a finish die. Then machining deformation is less and flow of work is not cut. If the number of sections is increased, a tooth shape closer to the complete product can be naturally obtained. | ||||||

| PURPOSE:To enable high productive machining of variable racks which have the related angles of torsion in such a way that reciprocating movement in the axial directions of a cutting tool is brought to be combined with revolving movement which is generated by engagement with a master rack. CONSTITUTION:In the condition that a carrier 11 is moved to the farthest left, and a cutting tool 7 is engaged with the right end part of a master rack 13, a raw material W is fitted on the carrier 11. A ram 3 is reciprocated up and down, which is followed by reciprocation of the tool 7, at the same time, it is given rotary motion from the rack 13. Then, the rack 13 is brought into contact with the raw material W, cutting is initiated, and the identical teeth to those of the rack 13 are created on the material W. And, since the rotary angle of the tool 7 to the movement rate in the longitudinal direction of the rack 13 is different depending upon the machining position, the raw material W can be productively formed in the teeth which vary the gear ratio in the longitudinal direction, namely, racks which have the related angles of torsion. | ||||||

| PURPOSE:To produce variable rackes through grinding work with high productivity by combining the rotary movement generated by the engagement of a master rack and reciprocating movement of a cutting tool and the relative shift of the master rack and a worked material. CONSTITUTION:A part of a master rack 13 is protruded on the front surface of a shifting base 1, and the teeth having a fixed gear ratio is formed on the protruded part. The rack 13 and a cutting tool 17 are engaged, so the tool 7 is provided with rotary movement by the rack 13 during reciprocating movement. As the left end part of the cam surface of a cam plate 27 has the curvature convex upward, the relative shift speed of this rack 13 for the shift base 11 decreases gradually accompanied with the shift of the shift base 11, and the teeth having the equal pitch to the rack 13 is formed. As the working process proceeds, the teeth having the gradually varying pitch namely variable racks are manufactured in high productivity through a gear-ratio changing mechanism. | ||||||

| PURPOSE:To enable an adoption of steering gear ratio to a preferable portion in a wide range, and remarkably improve a straight drive stability and steering effort, by providing a variable rack tooth directly in the rack bar. CONSTITUTION:The rack.pinion steering gear is provided with a rack bar 1, and this rack bar 1 is supported within the housing rotatably and shiftably in the direction of axial line, and to the housing is rotatably supported a pinion 3 meshed to a rack tooth 2 on the bar 1. The rack tooth 2 is provided by directly gear cutting the bar 1, and for this tooth 2 on the X-axis corresponding to the axial line of the bar 1, O shows the meshing part when in a straight drive, and those in its right and left show the standard rack pitch points 1-14. A variable pitch line a is for changing an axially shifting amount of the bar 1 for rotation o the pinion 3. In this way, a steering gear ratio can be adopted to a preferable portion in a wide range. | ||||||

| PURPOSE:To obtain this rack bar with high accuracy, by facilitating the manufacture of a gear cutting tool by elastically indenting a central portion of a tooth row of a rack bar blank before cutting gears and by cutting gears by using an ordinary gear cutting tool with a uniform tooth row. CONSTITUTION:A work 9, a blank of a rack bar 4, is formed in a round bar-shape, and gears are cut up to a point B positioned at a distance of l on the right side from a point A near the center from the point A. Here, a plurality of supports 10-10'' are prepared, and the support 10' at the center is mounted at a location that sinks from the both sides 10, 10''. A location 9a where gears are cut is elastically deformed by applying tensile force to the work 9 by each installing pull tools 11, 11' among each support 10-10''. Gears are cut between said distance l by means of a gear cutting tool 12 with a uniform cutting tooth 12a row, and a row of teeth 13 that the tooth roots 13a of the central portion are shallow and tooth roots 13n successively become deep with advance to both sides from the central portion is made up to the work 9. | ||||||
