    A method and an apparatus for shaving, rolling or similar ones of the tooth flanks of gears in which a gearlike workpiece which is to be worked is supported stationarily, however, rotatingly and is in a two flank meshing engagement with a toothlike tool. The tool carries out a rectilinear back-and-forth feed movement in a plane, which is parallel with respect to the workpiece axis, a plunge movement perpendicularly with respect to the workpiece axis and a swivelling movement about an axis which is directed transversely with respect to the feed direction. To produce crowned tooth flanks, the plunge feed and the swivelling movement of the tool is changed independently from one another in dependency of the respective position of the tool along the feed path. A rocking device is provided on which is arranged the tool and which also takes part in the back-and-forth feed movement and which furthermore can be driven pivotally about an axis which extends transversely with respect to the feed direction. Feed, plunge and swivelling movements are controlled corresponding with the pregiven flank line of the workpiece. An adjusting device is connected to the rocking device through a coupling member which is capable of accommodating a swivelling movement. The adjusting device includes a motor which drives a spindle, wherein the spindle cooperates with a spindle nut, to which is hingedly connected a coupling member which, in turn, is connected to the rocking device.

    专利说明:

    The invention relates to mechanical engineering, in particular, to machines intended for the finishing of tooth profiles of spur gears, for example, the method of sheaving, honing, fine plastic deformation and the like.
    The purpose of the invention is the expansion of the technological capabilities of the machine by obtaining a predetermined profile barreling.
    FIG. 1 shows an gear cutting machine; in fig. 2 shows an embodiment of the connecting link of the devices for rotation of the cradle; in fig. 3 - the same, another option; in fig. 4 shows the position of the tool relative to the side surface of the gear to be machined.
    On the frame of the 1 gear-shaping machine, between the centers of the front 2 and rear 3 heads, the processed gear 4 can be pivoted. In the vertical guides of the rack 5 with the ability to move along the arrow Z, a support 6 with an engine 7 is installed, carrying a carriage 8 made of the upper 9 and the lower 10 parts. In the circular guide 11, the upper part 9 of the carriage 8 is installed with the possibility of rotation around the vertical axis N. The lower part 10 of the carriage is reciprocating (in the direction of arrow R) moves in the horizontal plane relative to the support 6 by means of the engine 12 and the screw pair 13. In the arcuate direction 14, made on the lower side of the bottom part 10 of the carriage, there is a cradle 15 on which an instrumental head 17 is placed in a circular guide 16 with the possibility of angular rotation around the vertical axis P. In the tool head 17 with the possibility of rotation from the engine 18 mounted disk tool 19 (shaver). The axes H and P are coaxial and lie in the mid-plane of rotation of the disk tool 19.
    By turning the tool head 17 around the axis P, the angle of crossing of the axes M of Shaver 19 and N of the gear wheel 4 being adjusted is adjusted. At the same time, the axes M and N lie in parallel planes. By turning the top of the 9 carriage around the axis And
    This is the tool feed direction 19 (for example, the R direction).
    Cradle 15 with instrumental hovka 17, carrying a shaver 19, can
    Turn in the arcuate guide 4 around the Q axis. To reproduce this rotary movement, a special adjustment device is provided in the machine.
    In order to ensure that the disk shaver 19 travels along a set trajectory, each point of the tooth line of the wheel to be machined must correspond to a certain center distance a and determine the angle of rotation (or incision) cf, tf. The movements of the disk tool 19 are set by determining the path described by a point located on the outer diameter of the tool and are set by the machine control system. The coordination of the rotation movements qi depending on R is carried out by means of digital control.
    Adjusting device (figure 2) for the implementation of the rotary movement
    q consists of a motor 20 mounted on the console 21 of the lower part 10 of the carriage, a lead screw 22, rotated by the motor 20 and rotating in bearings 23 and 24, housed in the console 21, and installed without clearance
    on the lead screw 22 of the uterine nut 25 The engine 20 can be filled in the form of a hydraulic motor, a three-phase motor or a DC servomotor “If necessary, it can
    be downshifted. The axis 26 of the lead screw 22, installed with the exception of the possibility of axial movement, passes tangentially to the arcuate guide 14. It can also be installed parallel to the tangent to the arcuate guide 14. A hinge 27 is located parallel to the uterine nut 25, adjustable without clearance
    using an i-shaped connecting link 28, and the axis L of the hinge 27 runs parallel to the axis of swing Q
    lulgdeki 15.
    In addition, the connecting link 28 by means of a hinge 29 that is moved without gaps, whose axis K, which is parallel to the swing axis Q, is hinged
    3
    mounted on the plug 30, placed on the cradle 15.
    When the lead screw 22 rotates, the mother nut 25 moves to the left or right depending on the direction of rotation. In this case, the cradle 15 and thus the shaver 19 rotate around the Q axis against or clockwise, since the rectilinear movement of the uterine nut 25 in the direction of the arrow R is converted by means of the connecting link 28 n of the simplified arc-shaped guide 14 into a rotational movement (f of the cradle 15 .
    Axis 26 can have not only a horizontal position, but also a gap of any other, including a tangential position. Instead of the U-shaped connecting link 28, a sleeve-shaped connecting link located around the uterine nut or two connecting rods parallel to each other located on two sides of the uterine nut can also be used.
    In another embodiment of the connecting link (Fig. 3), one connecting rod 31 is applied. It is pivotally attached to the uterine nut 2.5 and to the cradle 1 5 by means of ball joints moved without clearance.
    Ditch 32 and 33. In this case, the console 21 additionally installs a strap 34, which, without a gap, enters a groove 35, fitted in a uterine nut 25, securing it from turning.
    With the help of these mechanisms, an appropriate polo is provided.
    tool during the processing of a given barrel-shaped teeth, a given tooth shape can have not only a convex shape, but also straight and concave portions. In order for the tooth to be needed to exactly match the specified shape, the average plane of rotation of the tool must always be perpendicular to the corresponding part of the tooth line of the wheel to be machined. The machine is designed for finishing processing of cylindrical gears with a disk tool under two-profile grounding conditions, while the radial forces arising during processing are directly perceived by the arcuate guide cradle having a large bearing surface, and the design of the rotatable tool head perceives only axial effort
