Description

1 The invention relates to a construction, in particular, to devices for forming reinforced parts by casting. The purpose of the invention is to improve the quality of the resulting contribution and reduce the labor intensity of their manufacture. FIG. 1 shows a device, a general view, in FIG. 2 shows section A-A in FIG. one; in fig. 3 — node 1 in FIG. 2; in fig. 4 and 5 - section BB in FIG. 2. The device comprises a hollow technological mandrel 2 in the form of a shaft placed in the bearing housing 1, a guide element 3 in the form of a sleeve with longitudinal grooves 4, hollow elastic inserts 5, as well as pipelines 6 with fittings 7. In the sleeve along the grooves 4, slots 8 are made; Inserts 5 are placed in the corresponding slot 4 and slot x 8, as well as in between the mandrel 2 and the body 1 and connected by means of fittings to the corresponding pipelines 6, placed in the gap. connected to a pressure source 9. The piping 6 in the housing 1 is secured with latches 10. In the manufacture of complex shaped pockets, in hollow elastic inserts 5, grooves 11 are inserted into the spacers 12. The device operates as follows. The mandrel 2 and the sleeve 3 with pipes 6 attached to the hollow elastic inserts 5 are positioned and 32 centered with respect to the hole in the bearing housing 1. The pipes 6 are secured in the housing 1 by means of clamps 10, made of a liner material, and connected to a source. Before filling the gap with an antifriction matrix melt (bronze, babbitt, compounds, etc.) in the cavity of the inserts 5, a fluid is supplied under pressure, causing deformation of the inserts 5 and nozzles 7, sealing the latter with the pipelines 6. After hardening and cooling of the antifriction material ( liner formation) proceed to disassemble the device. First, turn off the source 9 and relieve pressure in the system. This eliminates the deformation of the inserts 5, resulting in a gap between the mating surfaces of the inserts 5 and the formed liner, which makes it easy to disassemble in the next sequence: the sleeve 3 is removed in the axial direction, while the inserts 5 are disconnected from the pipelines b, which remain in the formed liner and are used to supply the working fluid to the bearing; lastly, spacers 12 are removed from the liner. Thus, the bearing is made ivayut with fully formed insert and channels for supplying lubricant is provided in which high accuracy of form and mutual arrangement of the pockets.
