Description

one

The invention is fireproof in the field of megatre processing and will find use in the manufacture of gears.

There are known devices for gear-jacking machines, which allow the removal of the chisel by means of a controlled mechanism, kinematically connected with the pusher.

The chain of the invention is to provide compensation for gaps formed during the wear process of the landing surface.

For this, the slide is fixed in place in the tractor mounted in the sunporg on two spherical supports, one of which is a toothed coupling half and the other is a spherical guide sleeve.

FIG. 1 is a schematic diagram of the device, FIG. 2 is a section through A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The dp retraction device consists of a worm gear - a 1W screw of a worm gear 2, placed in a support 3 housing,

Wheel 2 is provided with cylindrical and saddle pads, cut into inner

teeth that are in contact with the teeth of the half-coupling 4. A ring 5i is worn inside the chervite wheel, inside which the teeth are made, and the sap is similar to those made by niopesa2.

The half coupling 4 is provided with a spherical surface with a radius resting on the spherical surface of the sleeve 6, which is pressed into the housing of the Konecia worm gear divider.

The toothed half coupling has a barrel shape.

A cylindrical fit for wedge is located between the upper row of teeth of the ring 5 and the lower row of internal teeth, cut into the housing of the worm gear 2.

In the coupling half 4 there are guide slots in contact with the slotted nozzle 7, fixedly mounted on the tail end of the rod 8.

A guide bushing 9 is fastened to the gear half coupling 4 with slits along which the spline nozzle 7 slides.

The gap in the spline and gear connection is sampled by rotating the ring b and the guide tube 9 by means of; Points 1O and 11.

The spherical highlander of Pawaufgy 4 is constantly pressed against Bgupka 6 by spring 12, washer 13 and bolt 14,

In the middle part of the center, 8 is installed popzushka 15, with the help of which through spherical washers 16 and 17 and two are stubborn; the ball bearing 18 of the gear 8 communicates from the crank-and-rocker mechanism 19 in a progressive movement.

The lower part of the shtospep is located in the direction of the spherical bush 20 with a radius of g, on which are put two spherical liners 21 and 22. The design of the spherical insert 2O and the spherical inserts 21 22 provides adjustment of the optimum clearance between the scissor 8 and sleeve 2O,

With the aid of the withdrawal mechanism, operating from the main drive 23, a go-kagel 24 was brought in and out, reporting a reciprocating movement to the ram and carried out another withdrawal in addition.

The device operates with a single-piece image. Using the crank-and-crank mechanism 19 from the shaft of the main drive 23, the slider 15 moves from the top to the bottom. The force from the i-slide 15 is transmitted through self-aligning spherical washers 16 and 17 and the bearing 18 is transmitted very well 8. When moving the pistol 8 down, the shear guide nozzle 7 slides along the splined guide 5 located in the sleeve 9 and gears: that half coupling 4.

After lowering the shtodel to the lowest position, the rope of the pusher 24 rolls along the bevel of the mechanism 25, under the action of the compression spring the pusher 24 will move to the left.

At the same time, the axis of the shtosel 8 will turn relative to the angle R by a small angle, the gear half coupling 4 will turn together with the ram 8 by a small angle. The spherical washers 16 and 17 and the bearing 18 provide for a smooth rotation of the spindle at a certain small angle, while the spherical bushing 2O ensures the rotation of the spindle by turning the spherical liners 21, 22.

Dolby to departs on. a value of 0.5-O, 7 mm from the work piece and has the ability to rise freely,

The crank mechanism 19 lifts the ram 8 with a dol. At the expense of the bevel on the wedge of the mechanism for supplying 25, the ram 8 returns to its original vertical position.

The cycle of operation of the device is repeated.

During operation of the device, the compression spring 12 ensures a constant contact of the toothed coupling and the coupling 4 with the spherical sleeve 6.

In the process of adjustment and compensation of Yaznos - rubbing surfaces of the spline guides and the gear joint, screws 1O and 11 are used.
