The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Specific embodiment 1:
Fig. 1-Figure 10 forms specific embodiment of the utility model 1.The auxiliary mould of installing for railcar pantograph bearing that the present embodiment relates to, on maintenance platform, (not shown in FIG.) arranges fixed or portable auxiliary mould module (not shown in FIG.), two screw rod and three sizes and variform briquettings that length is different in described auxiliary mould module.
In the present embodiment:
Referring to figs. 1 through Fig. 4, one end of two screw rods respectively forms bolt head, the other end and is respectively with a nut, the size dimension of two screw rods and pantograph to carry guide rod identical, screw rod that two length is different is set with the railcar pantograph bearing of supporting different size; Two screw rods that length is different, comprise 22 of one of screw rod 1 and screw rod, and the length of one of screw rod 1 is short compared with 22 length of screw rod, and the front end of two screw rods is respectively provided with external screw thread, forms bolt head, and the front end of two screw rods is respectively provided with hex nut.
With reference to Fig. 5 to Figure 10, described three briquettings are cylinder block structure with the level, and the size dimension of boss and railcar pantograph bearing inner race match, with fitted bearing inner ring, by screw rod, exerted pressure bearing is pressed into bearing block in briquetting surface.The size and shape of three briquettings is different, and wherein, the projection width of the middle projection section 3-2 of one of briquetting 3 is equivalent to 80%, 90% or 95% of briquetting body 3-1; The projection width of 24 middle projection section 4-2 of briquetting is equivalent to 25%, 30% or 35% of briquetting body 4-1; The projection width of 35 middle projection section 5-2 of briquetting is equivalent to 70%, 75% or 80% of briquetting body 5-1, and in centre position, has through hole 5-3, with the railcar pantograph bearing of supporting different size.
In practical application, when subway vehicle pantograph bearing is installed, with 22 of one of screw rod 1 or screw rod, replace pantograph to carry guide rod near-end bearing is press-fited to operation; Rely on nut to screw in extruding briquetting far-end bearing is press-fited to operation, can complete subway vehicle pantograph bearing is installed.
The utility model, for auxiliary installation of the China's No. three line subways in certain city (GZML3) carbody pantograph bearing, relies on screw rod in Fig. 1 from a side, to stretch into bearing block through bearing, applies certain pressure bearing is pressed into bearing block.Opposite side is after on bearing holder (housing, cover), then is with briquetting 3, and nut screws in to exert pressure bearing is pressed into bearing block.All the other two press-fitting tools that briquetting is other pantograph bearing, only need briquetting boss to be engaged in bearing inner race, beat to complete to press-fit with rubber hammer.
