Abstract

The utility model belongs to dismounting tool for mechanical equipment, and particularly relates to a special tool for disassembling gears, shaft couplers, bearings, pins, shells and the like on the mainshaft of the large equipment. The pulling tool is mainly formed by connecting a disc, a separating disc, a pulling rod and a screw rod; pulling rod holes at the edge of the separating disc are superposed, pass through one end of the pulling rods and are positioned by nuts; the integral discs pass through one end of the pulling rod and are positioned by nuts; the dismounted parts are arranged between the separating disc and the disc; the screw rod is screwed in the central screw hole, and one end of the screw rod pushes against the shaft end of the dismounted part; and a force handle is arranged at the other end of the screw rod. The disc pulling tool has simple structure, is convenient for use and simple for maintenance, has wide practical scope, low manufacturing cost, can act uniform force on the parts on the shafts of large equipment, does not result in deformation or damage upon the parts on the shafts, and is easier to disassemble.

Description

Disk draws tool

Affiliated technical field

The utility model belongs to the plant equipment extracting tool, particularly the specific purpose tool that the gear on the main equipment main shaft, shaft coupling, bearing, pin, shell etc. are unloaded.

Background technology

Commercially available parts on shaft extracting tool is many hydraulic-driven at present, and it adopts several drag hooks to hold several points of part, by hydraulic drive part is unloaded.For the less part of stock size, this quasi-tradition extracting tool is relatively good usefulness, but the gear of many main equipments, shaft coupling, bearing, pin, shell etc. are when safeguarding or repair, use general dismounting to draw tool then can't finish mutual disengaging, because large-scale part is easy to generate the each point unbalance stress when dismantling with it, adopt more existing simple and easy or compulsory means to be easy to cause parts damages, distortion maybe can't break away from.

Summary of the invention

Generally draw tool can't finish the problem that breaks away from mutually of axle upper-part of main equipment in order to overcome use, the utility model provides a kind of tool that draws, and it is simple in structure, and is easy to use, easy to maintenance, the dismounting of the axle upper-part of suitable big machinery.

The technical solution of the utility model is: originally draw tool mainly to be connected to form by disk, separation disk, pull bar and screw rod, separating the overlapping and end that be through pull bar of the tie rod hole of disk border is located by nut, whole disk is through an end of pull bar and is located by nut, split inloading part places and separates between disk and the disk, screw-in screw rod and screw rod one end are pressed on the axle head head of split inloading part in the disc centre screw, screw rod other end dress effort handle.

Described separation disk is by overlapping forming more than two, and overlapping aperture, its center is greater than the axle head head diameter of split inloading part and less than the diameter of split inloading part.

The structure of described effort handle is, a sleeve member is contained in the screw rod end by key, and two are fixed on the sleeve member outer wall with upper handle.

The beneficial effects of the utility model are: the Ben La structure of signing an undertaking is simple, easy to use, easy to maintenance, and usage range is wide, and cost of manufacture is low, and the axle upper-part application of force equilibrium to main equipment can not cause deformed damaged to the axle upper-part, dismantles more or less freely.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a separation disc structure schematic diagram of the present utility model.

Among the figure: main shaft 1, axle head head 2, nut 3, tie rod hole 4, separation disk 5, bearing 6, pull bar 7, screw rod 8, screw 9, effort handle 10, key 11, disk 12.

The specific embodiment

Referring to Fig. 1,2, this disk draws tool mainly to be connected to form by disk 12, separation disk 5, pull bar 7 and the screw rod 9 of integral body, separate disk 5 by forming at imbricate more than two, separate axle head head 2 diameters of overlapping aperture, the center of disk 5, simultaneously again less than the diameter of bearing 6 greater than the bearing 6 that is disassembled.Separate the overlapping and end that is through pull bar 7 of the tie rod hole 4 at disk 5 edges by nut 3 location, whole disk 12 is through an end of pull bar 7 by nut 3 location, bearing 6 places and separates between disk 5 and the disk 12, the end face of bearing 6 with separate the contact of disk 5 symmetry, screw in screw rod 8 in the center screw of disk 12, one end of screw rod 8 is pressed on the axle head head 2, and screw rod 8 other ends are installed effort handle 10.The structure of this effort handle is, by key 11 sleeve member is contained in screw rod 8 ends, is being fixed on the sleeve member outer wall with upper handle by two.By rotation urging handle 10, screw rod 8 moves forward, and can gradually axle head head 2 be pushed out the inner ring of bearing 6.

Claims

1. a disk draws tool, it is characterized in that: mainly connect to form by disk, separation disk, pull bar and screw rod, separating the overlapping and end that be through pull bar of the tie rod hole of disk border is located by nut, whole disk is through an end of pull bar and is located by nut, split inloading part places and separates between disk and the disk, screw-in screw rod and screw rod one end are pressed on the axle head head of split inloading part in the disc centre screw, screw rod other end dress effort handle.

2. draw tool by the described disk of claim 1, it is characterized in that: separate disk by overlapping forming more than two, overlapping aperture, its center is greater than the axle head head diameter of split inloading part and less than the diameter of split inloading part.
