专利摘要:
When grinding spiral bevel gears (1, 2) by the indexing method, in each case two tooth flanks at one of the bevel gears (2) can be machined on both sides of a tooth gap in one operation with a cup grinding wheel (5), the grinding flanks (51, 52) of which form an outer bevel ring. To achieve the object of grinding a satisfactorily meshing mating gear (1) in one operation, it is proposed to use a cup grinding wheel (7) to grind the mating gear (1), the grinding flanks (71, 72) of which cup grinding wheel (7) face one another and form an inner bevel ring. To generate width crowning, a cyclic additional movement of slight eccentricity can be imparted to the grinding wheels (5, 7). <IMAGE>

The invention relates to metalworking and can be applied when grinding mating pairs of conical wheels with circular teeth.
There is a known method of grinding a mating pair of conical wheels with circular teeth under running conditions with periodic dividing by two tools, one of which, made with one working surface relatively to the other, is machined on surfaces located on both sides of the depression of the wheel and the other made with one side facing the other side of the working surface, the side surfaces located on both sides of the gear tooth are processed, l,
A well-known method is used to grind pairs of wheels that do not have the ability to displace one another and must be mounted with extreme precision.
A known tool for grinding one of the pairs of mating gear wheels (gears) with circular teeth, the working surfaces of which are facing one another.
;. The prior art tool is not used to grind one of the gear pair wheels.
The purpose of the invention is the increase in accuracy in profile grinding.
The goal is achieved in that according to the grinding method, a pair of conical wheels with circular teeth under rolling conditions with periodic dividing by two tools, one of which is made with 1 and one relative to the other working surfaces, is machined on surfaces both sides of the trough of the wheel, and the other, made with working surfaces facing one another, are machined on side surfaces located on both
the sides of the gear tooth, the instruments are reported reciprocating along the non-coincident trajectories of m.
A path represents an OR circle or two arcuate portions with different curvatures, or two arcuate portions, connected to each other by rectilinear portions perpendicular to the lateral surface of the tooth or two arcuate portions with different centers,
The method is carried out with the aid of a tool for grinding the gear of a mating pair of conical wheels with circular teeth, the working surfaces of which face one another and constitute a conical inner ring.
Fig. 1 shows a schematic of the engagement of a mating pair of bevel gears with a two wheel engagement scheme in Fig. 2 — a grinding wheel with a grinding wheel; FIG. Fig. 4 shows the trajectory of the additional movement of the circle in the form of a circle; in Fig. 5 the same, in the form of two arcuate sections with different curvature; aa fig.b is the same, in the form of two arcuate portions, interconnected by straight lines portions directed perpendicular to the side surface of the tooth, in Fig.7 - two arcuate portions with different centers. .
The grinding of a mating pair of bevel gears with circular teeth. Gears 1 and wheel 2 are produced under conditions of general conditional polishing.
The corners of the top three of the pitch cone of the wheel and gear are denoted by §1 and $ 2. The height of the teeth depends on the tapered distance R. The grinding of the pair is carried out with two tools in the form of grinding wheels. A tool in the form of a grinding wheel 3. Produces machining of surfaces located on both sides of the depression 4 of wheel 2. With a tool in the form of a grinding wheel 5, the side surfaces located on both sides of the gear b gear 1 are machined. The tool in the form of grinding wheel 3 has grinding side surfaces A and &amp; , turned one relative to another, forming a conical outer ring. In the process of processing the wheel 2, the tool in the form of a grinding wheel 3 with the side surface profile A, B in the form of a conical outer ring is reported to rotate in the direction of arrow B. This movement is a cutting movement. In this case, the wheel 2 is reported with oscillating rotational movement — the running-in movement — in the direction of arrow F. The grinding wheel tool 3, along with the cutting movement, is driven by the rolling arrow coordinated with the movement along arrow F of wheel 2 and arrow. 3 will be in a cyclic motion around the intersection point P of the axis 00 of the wheel 2 with the tooth aa line of the height of the tooth. The side surfaces of the depression 4 of the wheel 2 are ground, the lower side surface is treated with an external polishing side surface A, and the upper side surface is machined with an internal and basic side surface B. In this case, processing one side surface I or K is done from the outside to the inside, processing the other side surface is made from the inside out, i.e. when the collar is run-in. Sa in one or another direction of movement along arrow F. Therefore, during the movement of cutting along arrow 6, circle 3 has a cyclic additional movement along arrow li with a small eccentricity. Non-coincident trajectories can have the form of a circular trajectory in the form of a circle of radius R |, a cyclic trajectory in the form of two arcuate portions with different curvature R R- with center 0, a trajectory in the form of two arcuate portions interconnected by straight lines in - t , P - h, directed perpendicular to the side surface of the tooth, the trajectory of the two arcuate sections with different centers 0 and O. The gear 1 is produced and the grinding wheel 5 in the form of a grinding wheel, which grinds the lateral surfaces located on both sides of the tooth, the ba 6 gears 1 and the wheels 4 connected to the void 6. Circle 5 is reported to move in the direction of the axis along the arrow M. When machining gear 1 around 5, relative movements are identical to those of wheel 2 and circle 3 when machining wheel 2. The tool in the form of a grinding wheel 5 has thin side surfaces D and C that face each other and form a conical inner ring. The method is carried out as follows. . In the flat wheel 7 Q, the intersection lines of the cavity between the teeth C-C and L-b of the teeth and the lateral surfaces between the teeth are created by a grinding wheel with an outer radius g; and an inner radius r that rotates around an axis. This rotational movement in turn is a cutting movement. Then the grinding wheel makes a cyclical movement around its axis (circular motion). Both movements are carried out in the direction of the arrow. N. The radius of curvature of the concave side surface is obtained from the sum of the radius r, the grinding wheel and the radius of the additional movement. The line of intersection of this concave shape is also ё.ts with a circular arc. The concave side surface of the tooth in this plane still has an approximate shape of a circular arc, since both movements are along radius r; and the complementary movement radius is layered on top of one another. The curvature of the side surface of the tooth approximately corresponds to the inverse of the radius g; and some more of it. If the wheel and gear are made using tools in the form of grinding wheels 3 and 5, and an additional movement is layered on both or just one tool, a tooth bulge along the length will be beneficial, which leads to a limited bearing width and thus to an advantageous ability to move the wheel. The wheel and gear can be made in one working operation. The contact between the grinding wheel and the product (wheel or gear) is no longer carried out. line of contact. With additional movement, the contact area moves on the concave side surface from the outer to the inner ends of the tooth and on the convex side surface from the inner to the outer ends of the tooth. In this way, it is possible to vary the contact pattern of the wheel and gear. The proposed method makes it possible to increase the accuracy of production of the conjugated pair and to create the possibility of varying the spot of contact.
