Embodiment Construction

[0036] The invention relates to a method of repairing the teeth of a ring gear 3 by means of a removable machining device 1 .

[0037] The device comprises a frame 11 and a movable member 13 supporting a cutting member 15 movable along several axes relative to the frame 11, possibly orientable. The tooth shape to be reproduced may be a planetary tooth shape including planetary sections.

[0038] Advantageously, the method according to the invention can be carried out in situ, that is to say without removing the ring gear from its seat, in particular without removing the ring gear from the collar of the rotating machine, which The machinery can be a rotary oven, dryer, sugar diffusion system, pebble mill or ball mill.

[0039] Said method comprises the following steps of performing a machining operation on the tooth 4:

[0040] - the attachment of said processing device 1 to the ring gear 3 by the action of fasteners 12, 12', rigidly attached to the frame of the processing de...

Abstract

Method and processing device (1) for repairing the teeth of a ring gear (3), the processing device comprising a frame (11) and a movable part (13) supporting a cutting part (15) capable of moving along multiple a shaft moves relative to said frame (11), said method is carried out in situ without removing said ring gear from its support (2), said method comprises the following steps of machining the teeth (4) :- Attaching the processing device (1) to the ring gear (3) by the action of fasteners (12, 12') rigidly attached to the frame, meshing with the flanks of said ring gear (3), - determining the position of said machining device (1) relative to the tooth (4) to be machined, by approaching the flank (42; 42') of the reference tooth, so Said flanks (42, 42') are positioned relative to the crests (43; 43') of the reference tooth, in the opposite direction to the flank (41) of the tooth (4) to be machined, the reference tooth being the tooth to be machined ( 4) or the immediately preceding tooth (4'), - machining the flank (41) of the tooth (4) to be machined in an automatic manner by controlling said cutting element (15) according to a predetermined machining operation, The machining operations are digitally recorded in memory.

Description

technical field [0001] The invention relates to a method of repairing the teeth of a ring gear by means of a machining device, and to a machining device suitable for carrying out said method. Background technique [0002] The field of the invention is that of large rotating machines, usually with substantially horizontal shafts, such as those used in the chemical, mining or sugar industries, equipped with large ring gears that drive A rotating machine that is turned by a pinion and motor assembly. This type of rotating machinery includes rotary furnaces, ball mills, horizontal ball mills, and sugar diffusion systems, among others. [0003] For this type of machinery, repeated contact between the teeth of the pinion and the teeth of the ring gear is a source of wear, which can exhibit various characteristics resulting from the relative relationship between the drive system including the pinion and the driven machine Positional configurations and all kinds of motion of machi...
