Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings.
The utility model provides a split type cylindrical roller bearing outer lane handling assembly fixture of locomotive traction motor, includes fixed disk 1 and supporting disk 2.
As shown in fig. 2 and 3, the outer edge of the support plate 2 is provided with arc openings 5 (the number of the arc openings is the same as that of the cylindrical rollers) matched with the cylindrical rollers 14 in the outer ring 13 of the cylindrical roller bearing, and a support step 6 for supporting the cylindrical rollers 14 is arranged between the adjacent arc openings 5; the supporting disk 2 surface corresponds and is equipped with hexagon socket head cap screw hole 8, and hexagon socket head cap screw hole 8 is the blind hole.
As shown in fig. 4 and 5, the fixed plate 1 is centrally arranged on the extending column 3, and the end part of the extending column 3 is provided with a lifting bolt 4. Hexagonal bolt grooves 10 are evenly distributed on the edge of the fixed disk 1, and positioning protrusions 9 are arranged on the bottom surface of the fixed disk 1.
As shown in fig. 6 and 7, the surface of the support disc 2 is connected with the fixed disc 1. The fixed disc 1 is fixedly connected with the supporting disc 2 through six inner hexagon bolts 11, and the inner hexagon bolts 11 are installed through a flat gasket 12. And screwing and locking the hexagon socket head cap screw 11 after the corresponding hexagon socket head cap screw groove 10 and the hexagon socket head cap screw hole 8 correspond. The positioning projection 9 fits with clearance fit in the central aperture 7 of the support disc 2.
For preventing bearing damage in the assembling process, the supporting disk adopts brass H62 preparation, guarantees that cylindrical roller can not harm, and for lightening frock weight, nylon material is chooseed for use to handheld partial fixed disk simultaneously, convenient operation.
