Client expectation<\/h4>\n

Given the importance of the co-extruder in their manufacturing process, a French plasticisation company wished to entrust to us the overhaul of the only reducer they had in stock in order to guard against a possible mechanical breakdown.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n

DV GROUP Solution<\/h4>\n

In fact, a breakdown of the co-extruder would systematically lead to the stoppage of half of production and as the lead time for the supply of a new reducer would be extremely long, out client could not afford not to have a product in stock. In order to be totally worry-free regarding the condition of the only reducer they had in stock, it was imperative to overhaul it.<\/p>\n

Work carried out<\/h4>\n

DV GROUP technical solution:<\/p>\n

3D printing of the shafts\u2019 clamping matrix:<\/p>\n

    \n
  • Given the particularity of an extruder reducer with 2 indexed output shafts, we suggested to our client modelling and 3D-printing the shafts\u2019 clamping matrix in order to guarantee their correct positioning during refitting.<\/li>\n<\/ul>\n

    Removal\/refitting and overhauling of the reducer in the workshop:<\/p>\n

      \n
    • Visual monitoring of the product<\/li>\n
    • Measurement of the axial play in the gearing rows<\/li>\n
    • Benchmarking of the bearing references<\/li>\n
    • Visual appraisal of tooth spacing (search for the usual signs of deterioration of the teeth)<\/li>\n
    • Monitoring of the span of the teeth with an impression of the teeth on scotch tape<\/li>\n
    • Removal of the gearing rows<\/li>\n
    • Monitoring of the size and geometry of the shaft rows<\/li>\n
    • Magnetic particle inspection of the teeth<\/li>\n
    • Inspection of the key grooves and connector spokes by bleeding<\/li>\n
    • Inspection of the casing size<\/li>\n
    • Cleaning of the reducer and gearing rows<\/li>\n
    • Reassembly of all the bearings and joints<\/li>\n
    • Monitoring and adjustment of the span of the teeth and indexation<\/li>\n
    • Adjustment of the axial play in the gearing rows<\/li>\n
    • Reassembly of the cover, waterproofing and upper casing<\/li>\n<\/ul>\n <\/div>\n <\/div>\n<\/section>\n\n
