Abstract
The utility model relates to a bearing dismounting device which is characterized by being composed of a lead screw, a manual wrench arranged on the upper portion of the lead screw, a nut meshed with the lead screw, connecting rods arranged at two ends of the nut and a group of grab hooks in sleeved connection with the connecting rods. The upper portions of the group of grab hooks are respectively provided with a lantern ring, and the lantern rings are in sleeved connection with the connecting rods. The bearing dismounting device has the advantages of being simple in structure and convenient to use, hardly damaging a bearing in the dismounting process, reducing labor intensity of overhaul workers, improving working efficiency, being safe and reliable and reducing on-site accidents.
Description
Technical field
The utility model relates to the bearing extractor technical field, particularly a kind of bearing disassembling device.
Background technology
In the plant equipment maintenance process, often need the bearing removal of rotatable connecting portion be fallen.Tradition dismounting bearing is earlier bearing to be heated, and adopts iron hammer to impact bearing then, separates with axle until bearing, and its drawback is to impact bearing with iron hammer very easily to cause damage of bearings, causes waste.A kind of in addition mode of dismantling bearing is to adopt hydraulic jack to drive grapple directly to grab bearing, but this extracting tool is heavy, complex operation, and cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of bearing disassembling device, and this apparatus structure is simple, and is easy to use, practical, and with low cost.
The purpose of the utility model realizes through following technical proposals:
The bearing disassembling device of the utility model; By leading screw, be located at the manual wrench on this leading screw top, therewith the nut of leading screw engagement; Be located at the connecting rod at said nut two ends; One of the connecting rod socket group of grapple is formed therewith, and this group of grapple top is respectively equipped with the collar, the described collar and connecting rod socket.
The beneficial effect of the bearing disassembling device of the utility model is:
Engagement through leading screw and nut has realized moving up and down of nut, has driven grapple and has moved up and down, and has realized the dismounting of bearing; Simple in structure, easy to use; In unloading process, be difficult for damage of bearings has been alleviated maintenance worker's labour intensity, improved operating efficiency; And this device is safe and reliable, has reduced the generation of field accident.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model sketch map in use.
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2, the utility model bearing disassembling device is characterized in that by leading screw 1; Be located at the manual wrench 5 on this leading screw 1 top; With the nut 2 of said leading screw 1 engagement, be located at the connecting rod 3 at these nut 2 two ends, one group of grapple 4 of connecting rod 3 sockets is therewith formed; These group of grapple 4 top is respectively equipped with the collar, the described collar and connecting rod 3 sockets.
The method for using of this device is: at first make grapple 4 be hooked in bearing to be removed 7 bottoms; Bottom with leading screw 1 withstands on the axle 6 that cooperates with bearing 7 to be removed again; The rotation manual spanner 5 then, make leading screw 1 bottom firmly withstand axle 6 ends downwards, simultaneously; Grapple 4 is upwards carried bearing 7, until bearing 7 is unloaded.
