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 for repairing the teeth of a ring gear (3) and machining device means (1) comprising a frame (11) and a moving part (13) bearing a cutting member (15) that can be moved along a plurality of axes with respect to the frame (11), said method being implemented in-situ without dismounting the ring gear from the support (2) thereof, said method comprising the following steps for implementing the machining of a tooth (4): - attaching said machining device (1) to the ring gear (3) by the action of tightening parts rigidly attached to the frame of the machining device, engaging with the flanks of the ring gear (3), - defining the position of said machining device (1) with respect to the tooth to be machined (4) by abutting on the flank (42; 42') of a reference tooth, the flank (42, 42') being situated, with respect to the summit (43; 43') of the reference tooth, in the direction opposite the flank (41) of the tooth to be machined (4), the reference tooth being the tooth to be machined (4) or an immediately preceding tooth (4'), - performing the machining of the flank (41) of the tooth to be machined (4) in an automated manner by control of the cutting member (15) according to predetermined machining operations recorded, in digital form, in a 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...
