This invention relates to repairs and may be applied when reconstructing gear wheels.

The aim of the invention is the expansion of technological capabilities by surfacing gears of various sizes and increasing productivity.

The drawing shows the proposed device, obsh, i view.

Device for surfacing the ends of the teeth

sh.e command to stop vrash, fused gear and work welding head. The mouthpiece 16 rises up the arrow "d. The body of the mandrel is rotated in the direction of the arrow and the flux is poured out from the bowl 11. Then remove the weld gear 10 and rotate the housing 1 to its original position.

The cladding is performed with the elevation of the deposited material above the plane. The tailshester consists of body 1, in which the tip is 2-3 mm.

bearings installed sleeve 2, bring-To create an allowance for mechanical rotation in the direction of the arrow in the worm

wheel 3 from the leading shaft 4 connected to an electric motor. In sleeve 2, stiff processing along the thickness of the teeth the gear rim of the weld gear is heated in an inductor of mid-frequency setting 25

Coy 5 fixed two parts 6 and 7 of the mandrel. . Ki and opressovyvayut in the stamp. At the free end of the mandrel part 7 of the set-after punching, annealing is performed, the replaceable gear 8 is punched, the sewing and mechanical treatment is reversed in contact with the pinion gear. Then it is made by the mechanic 9. At the free end of the part 6, a fixed treatment of the teeth, including the precision of the weld gear 10, which is gear milling, gear rounding and

enclosed in bowl 11. On disk 12, co-shaving. The machined gears are attached rigidly with the sleeve 2, they are positioned to undergo carburization, hardening and release an adjustable stop 13, which interacts with the contact device 14.

The contact device 9 is electrically connected with the electric motors for driving the rotation of the shaft 4 and feeding the welding wire 15 passing into the mouthpiece 16 of the welding head. The contact device 14 is electrically connected with the electric motors for driving the rotation of the shaft 4 and the welding head. Case 1 has the ability to be moved in an easily accessible place. An increase in tuning in the adjusting mode according to boom-performance is achieved by means of an avca-a, for which the device is equipped with an electric-driven body turning.

The device works as follows.

At the free end of the mandrel part 7, a gear-copier 8 is installed, similar to the 5th gear, and interacting with the gear-copier is adjusted.

contact device 9. On the free endDevice for surfacing the ends of the teeth

parts 6 of the mandrel install e-gears overlay, comprising a housing, a mandrel for

my gear 10. Turn the fasteners of the weld gear, swivels 1 weld surface with a gear head with a feed mechanism proximately to the end of the welding rod 15. equipped with an electric drive, the gears 13 put the stop 13 on the preset weld copier, A fixed number of teeth fixed at the end and poured into the tees, and a mechanism for turning the mandrel, distinguish 11 fluxes. Turn on the device. It is based on the fact that, in order to expand, techno-smelting is performed on each end of the tooth. logical capabilities due to the deposition of „17 .. gears of various sizes and increase

ku Resource recovered gears not lower resource newly manufactured.

The device allows you to expand technological capabilities, improve the performance of surfacing, apply a multi-maintenance.

The changeover of the device for restoring different sizes of gears consists in replacing the gear-copier, setting up an automatic shutdown of the device after surfacing a predetermined number of teeth and mechanizing the impact of the flux from the welding bowl.

Claims (1)

Invention Formula separately. Commands to turn on and turn off the motor of rotation of the shaft 4 and feed the welding wire 15 are given by the contact device 9, the roller of which moves in the direction of the arrow. In the moment performance, the mandrel turning mechanism is equipped with an independent electric drive of its rotation and two contact devices, electrically stopping the rotation of the weld-up gear-JQ associated with the drives of the mandrel turning 10 does not include the wire feed motor; the mandrel is equipped with an adjustable stop interacting with the first contact device , and the scraper copier is placed at the end of the mandrel, opposite to the end to set the weld quantity of teeth, the stop 13 of the impact gear, with the opportunity interacts with the contact device 14, I submit with the second contact device. welding wire 15. The duration of stopping the rotation of the weld gear and the supply of welding wire counts the time relay. After surfacing, we sew a command to stop the vrash, as well as the weld gear and the welding head. The mouthpiece 16 rises up the arrow "d. The body of the mandrel is rotated in the direction of the arrow and the flux is poured out from the bowl 11. Then remove the weld gear 10 and rotate the housing 1 to its original position. Surfacing is performed with elevation of the deposited material above the plane of the ends of 2-3 mm. For each treatment over the thickness of the teeth, the gear rim of the weld gear is heated in an inductor of a mid-frequency unit and molded into the die. After stamping, annealing is performed, shaving. The machined gears are subjected to carbonitriding, quenching and letting go in an easily accessible place. Increased productivity is achieved through avku. Resource recovered gears not lower resource newly manufactured. The device allows you to expand technological capabilities, improve the performance of surfacing, apply a multi-maintenance. The changeover to a device for restoring various gear sizes involves replacing a gear-copier installed in an easily accessible place. Increased productivity is achieved by automatically stopping the operation of the device after surfacing a given number of teeth and mechanizing the impact of the flux from the welding bowl.
