Abstract
The utility model discloses a roll bearing mounting tool, which belongs to the field of steel rolling equipment. The tool comprises a hanging ring (1), an upper cover plate (2), a connection rod (3), a bolt (4), a wrench (5), a slider (6) and a bottom plate (7), wherein a nut is added between the hanging ring (1) and the upper cover plate (2) so as to be connected with the connection rod (3); the upper cover plate (2) is mounted on the connection rod (3) through a screwed hole; and the bottom plate (7) is connected with the connection rod (3) through adding the nut in the screw thread of the middle of the bottom plate (7). The utility model has the advantages that: the problem that a roll bearing needs to be split into blocks and then assembled block by block in the primary installation or in the assembly process for overhauling and replacement is solved; the roll bearing can be quickly and easily installed and replaced under the condition of ensuring the equipment safety and completion; the cost performance is high; and the manufacturing is easy.
Description
Technical field
The utility model belongs to steel rolling equipment specific purpose tool technical field, and a kind of roll bearing erecting tools particularly is provided, and is applicable to similar quick, safe, easy installing of equipment such as steel rolling equipment workroll bearings.
Background technology
Move two hot rolling line milling trains of hot rolling homework department of steel company and be respectively the deisgn product that western mark company and weighs designing institute, operation roll of mill all adopts the mounting means that four row bearing matches with two row thrust bearings in the design, the four row bearing of two production lines is respectively style of opening and sealed structure, all is not equipped with special-purpose erecting tools in the design.Find in the use that because of no specific purpose tool, must at first four row bearing be disassembled during installation, and then respectively inner ring, outer ring, retainer etc. be contrasted in the bearing block of packing into according to sign, installation process wastes time and energy; For the bearing of closed type, the outer ring falls into undesired extruding intermediate seal during assembling simultaneously, and the result causes sealing quick inefficacy, and maintenance repair simultaneously is difficult for changing, and the equipment operation exists hidden danger, the service life of bearing to can not get good guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of roll bearing erecting tools, has solved the roll bearing piecemeal that need disintegrate again and return the problem of dress in installation process, is used in the installment work of relevant similar devices.
The utility model comprises suspension ring, upper cover plate, connecting rod, bolt, spanner, slide block, base plate.Add nut in the middle of suspension ring and the upper cover plate, be connected with connecting rod, upper cover plate is mounted on the connecting rod by screwed hole, processes according to the size of bearing, has guaranteed the general of different size bearing.
The base plate neutral threaded hole adds nut with connecting rod and is connected, and two square grooves of processing allow slide block to be free to slide on it, and process corresponding baffle plate, and when slide block slided into the position that needs, the bolt that is installed on the baffle plate screwed, and can use.
Slide block is formed by two, uses steel to manufacture, and the necessary strict guarantee of scalable direction prevents interference.
Connecting rod is the double thread straight-bar, upper cover plate central punch and machining screw, and upper cover plate is mounted on the connecting rod by screwed hole, adds nut in the middle of suspension ring and the upper cover plate, is connected with connecting rod again; During use, upper cover plate rotates to an angle, the space that provides the operation slide block and use spanner;
Operation roll of mill belongs to the core component of milling train, therefore require bearing operate steadily, at a high speed, high capacity.For guaranteeing the intact assembling of roll bearing, increase newly and designed simple and practical special bearing globality erecting tools, designed and be used for the suspension ring that overhead traveling crane is hung up, upper cover plate is used for pushing down the surface that bearing makes progress, base plate exceeded bearing surface bottom slightly after instrument was put into bearing inside, designed slideable slide block especially, slide block stretches out and can hold up the bearing bottom, slide block is regained withdrawing from fast of implementation tool, simultaneously can scratch bearing body assembly and bearing block inwall, use is simple, has realized the installation fast and safely of roll bearing.After using this novel erecting tools, the replacing of roll bearing is time saving and energy saving, does not have to occur because of assembling the improper stopping accident that causes again.
The utility model lay particular emphasis on solve roll bearing first install or assembling process that maintenance is changed in need piecemeal to disintegrate after again block-by-block return the problem of dress, can be good at alleviating shortage of manpower, pressure it is pressed for time in the bearing installation, can guarantee under device security and the complete situation, fast, the installation and the replacing of roll bearing carried out in the labour-saving, the cost performance height is made simple and easy.
Description of drawings
Fig. 1 is a roll bearing erecting tools schematic diagram.Wherein, suspension ring 1, upper cover plate 2, connecting rod 3, bolt 4, spanner 5, slide block 6, base plate 7.
The specific embodiment
The utility model comprises suspension ring 1, upper cover plate 2, connecting rod 3, bolt 4, spanner 5, slide block 6, base plate 7; Suspension ring 1 add nut with upper cover plate 2 centres and are connected with connecting rod 3; Upper cover plate 2 is mounted on the connecting rod 3 by screwed hole, and base plate 7 neutral threaded hole add nut with connecting rod 3 and are connected.
With bearing to be installed clean lubricated after, be placed on two parallel bases, hang by suspension ring 1 with overhead traveling crane or half arm this instrument is sling, vertically put into bearing inside, when treating that upper cover plate 2 is stuck in the bearing upper surface, unclamp bolt 4, slide block 6 is extend out to the bearing lower surface, screw bolt 4 chucking bearing bottoms, the whole bearing of slinging is put into off-the-shelf bearing block, realizes the Fast Installation of bearing.
Claims (4)
1. a roll bearing erecting tools is characterized in that, comprises suspension ring (1), upper cover plate (2), connecting rod (3), bolt (4), spanner (5), slide block (6), base plate (7); Suspension ring (1) add nut with upper cover plate (2) centre and are connected with connecting rod (3); Upper cover plate (2) is mounted on the connecting rod (3) by screwed hole, and base plate (7) neutral threaded hole adds nut with connecting rod (3) and is connected.
