Abstract

The invention relates to machine tools, in particular to gear shaping machines operating under rolling conditions. The purpose of the invention is to improve accuracy by adjusting the operation of the rocker mechanism according to a sinusoidal law. In the machine caliper, a ram 1 with a rocker mechanism 2 and a dolly 3 is placed. On the ram 1 there is a serrated rail 4, which is in engagement with gear 5, which is kinematically connected with a gear train consisting of a pair of wheels. 6 and 7 are not round. One of the wheels of this pair through the setting body 8 and the summing mechanism 10 is kinematically connected with the dividers gear 12 1, and through the settings body 9 and the summing gear - with the dividers gear 13 of the separating table 14. The gear gear is set to work in antiphase with - The linch mechanism 2. Both mechanisms reproduce sinusoidal motion with the same parameters. The machine is driven by an electric motor 15, kinematically connected with the drive shaft 16. 2 Il. with S (Oh with

The invention relates to machine tool construction, in particular, to gear-shaving machines operating under conditions of | bkata, and is improved by Yiy ustroystza according to the author. Saint 1085714 The purpose of the invention is to improve accuracy by adjusting the work of the rocker mechanism according to a sinusoidal law.

FIG. 1 shows the kinematic diagram of the machine; in fig. 2 - fragment of Ychema wheel of non-circular shape. The gear shaping machine contains 1 tossel 1 with a rocker mechanism 2 4 dolby 3. On the ram 1 fixed i | a gear rack 4 j, which is in engagement with gear 5, on the total 4 wheel with which the wheel 6 is installed The gears of Lenia with the wheel 7, non-circular forg-1Y, are: gears 6 and 7 are set up in antiphase operation with rocker mechanism 1 2. Moreover, both mechanisms reproduce a sinusoid of the same size and shape

 Wheel 7 of non-circular shape by means of kinematic chains containing tuning bodies 8 and 9, and cyr-nsiH-mechanics 1 and 10 and 11, are connected to the division gears 12 and 13, respectively, of 1 slot and casting table 14, on which the workpieces are installed.

The motor 15 is kinematically coupled to the drive shaft 15.

The machine works as follows

When the motor 15 is turned on, the rotational motion of the drive shaft 16 is received, each turn of which is converted into one double stroke of Stossel-1 (movement II) sinusoidally.

Reciprocating movement of the sttoss; t by means of a gear-pinion gear 4-5 converts 13 reciprocating rotational movement of the pinion wheel 5. This movement, also carried out along a sinusoidal

Law5 by means of a gear train consisting of a pair of wheels 6 and 7 of a nekrula, working in antiphase with the rocker mechanism 2, is converted into a reciprocating rotational movement, characterized by a linear law. This movement through the setting body 8 and the DIM SECONDY mechanism 10 is communicated by the dividing gear 12 at 1 slot 3 (movement B), and through the tuning body 9 and the summing mechanism 11 to the dividing gear 13 of the dividing table 14 (movement B,). As a result, the hollow to 3 and the dividing table 14 with the workpiece, along with the rolling movement from the corresponding chain, also perform relative screw movement, reproducing the helical gears received from its Jl line of the tooth. At the same time, the bandage (the sonic movement is made up of the reciprocating movement of P | shtosel 1 and the reciprocating rotational movements coordinated with it B of the helical gear 3 and B ,, of the dividing table 14 into the opposite sides. The split table is rotated by half of the total angle required to provide the required angle of inclination of the teeth of the helical gear.
