Abstract
The utility model relates to a wrench for disassembling an oil-film bearing locking device, which solves the weaknesses of the prior art that when disassembling the oil-film bearing locking nut, the required labor intensity is large, the disassembling time is long and the like. The utility model adopts a technical scheme that: the wrench for disassembling the oil-film bearing locking device consists of locking ring 1, a locking hole 2 on the locking ring, a moment arm rod 3 which is connected with the locking ring 1, an arm hole 4 on the moment arm rod 3, and a connection hoisting hole 5 and a connection hole 6 on the locking ring. With the wrench, the working efficiency for disassembling the nut of the bearing locking device is greatly improved, the labor intensity and the operation safety coefficient are obviously reduced, and the service cycle of the oil-film bearing locking nut is also prolonged.
Description
Technical field
The utility model relates to mounting and dismounting tool, specifically belongs to the spanner of dismounting filmatic bearing locking device.
Background technology
Present domestic relevant industries great majority adopt the method for hydraulic locking apparatus dismounting, hang with cantilever to be used, and reach the purpose of dismounting bearing.But because the moment that this device can provide is limited, when dismounting filmatic bearing locking nut, often need pay very big strength, just can be with its bearing lock nut dismounting, the labour intensity that needs is big, promptly because the hydraulic locking apparatus operational forces is less, the locking hydraulic means can only provide the moment of 10N.m, dismantle normal locking nut and generally need 40～50 minutes, the nut of dismounting distortion then needs 2～4 hours, if and, then can't dismantle for the bearing lock nut that has been out of shape.Thereby influence normal maintenance time limit progress and equipment operation, and it is big to implement difficulty.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of lever principle of utilizing is provided, and increases moment, and little, the easy dismounting of labour intensity, raising are disassembled into the spanner that purpose is exclusively used in the dismounting of filmatic bearing locking nut.
Realize the technical measures of above-mentioned purpose:
A kind of spanner of dismantling the filmatic bearing locking nut, it is: its by the locking hole on retaining ring, the retaining ring, be connected in and connect lifting eye on the arm bar of retaining ring, the arm hole, retaining ring on the arm bar and connecting hole is formed.
It is: the length of arm bar is 1.1～1.7 times of retaining ring diameter.
It is: connecting hole connects two at least on retaining ring, and its pore size matches with the aperture that is connected on the bearing lock nut.
It is: the size of the locking hole on the retaining ring matches with the bearing lock nut external diameter.
The utility model compared with prior art, its characteristics: time spent of nut of a filmatic bearing locking device of dismounting shortened to 20 minutes by original 40 minutes, one of the dismounting of slight deformation locking nut shortened to 30 minutes by original 2 hours.The nut operating efficiency of promptly dismantling bearing locking device greatly improves, and has obviously reduced labour intensity and job safety coefficient, the life cycle that also prolongs the filmatic bearing locking nut simultaneously.
Description of drawings
Fig. 1 is the structural representation of the spanner of dismounting filmatic bearing locking nut
The specific embodiment
Be described in detail below in conjunction with accompanying drawing:
A kind of spanner of dismantling the filmatic bearing locking nut: processing retaining ring 1, locking hole 2 on the retaining ring 1 of processing matches with the external diameter of the bearing lock nut that will dismantle, 7 connecting holes 6 that on processing on the retaining ring 1, distribute with locking nut, match with the aperture that is connected on the bearing lock nut in the aperture of this connecting hole 6; According to the length of arm bar 3 be retaining ring 1 diameter 1.1/1.5/1.7 doubly, arm bar 3 is processed into taper, and in the small end process arm hole 4 of arm bar 3, adopt welding manner to be connected in retaining ring 1 at the big end of arm bar 3; Welding lifting eye 5 on retaining ring 1.
Use principle
During use, retaining ring 1 is enclosed within on the locking nut; Rotating to an angle to make has 2 and above connecting hole 6 screws to align with the screw of locking nut in the wrench retaining ring 1, insert two bolts.Steel cable is passed in the arm hole 4 of arm bar 3, the other end hangs up on the suspension hook of crane; The control overhead traveling crane rises, and steel cable motive force armed lever 3 produces moment, applies reverse rotation moment by 2 bolts to nut, makes locking nut loosening.Rotated 45 when spending when crane draws high locking nut, sling with lifting hole(eyelet) 5 then, this spanner unmount staff has just been spiraled locking nut with some other instrument dismantle.
