Abstract

A double-fed wind-driven generator bearing assembly and disassembly tool manly relates to the field of bearing disassembly. The tool comprises a nut, a disassembly baffle, a screw rod or a bolt, a connecting plate provided with lugs and an auxiliary tool; the auxiliary tool is connected with the screw rod via the disassembly baffle to form a scaffold structure; the auxiliary tool is provided with a cavity for installing the lugs of the connecting plate provided with the lugs. The tool disclosed by the utility model is mainly used to assemble and disassemble a wind-driven generator bearing, can effectively protect an insulating coating of the bearing, saves labor to assemble and disassemble the bearing, overcomes the defect that the bolt of the connecting screw rod behind the connecting plate will deform due to the too large force, can work even without a lifting jack, and has simple structure, low cost and high reliability.

Description

A kind of double-fed wind power generator bearing combination dismounting frock
Technical field
The utility model relates to wind-driven generator, is specifically related to a kind of double-fed wind power generator bearing combination dismounting frock.
Background technology
Because the double-fed wind power generator bearing adopts insulation bearing, costs an arm and a leg, so aspect bearing removal, will pay special attention to protect bearing; A kind of double-fed wind power generator bearing combination dismounting frock is arranged at present; It can effectively protect the bearing of generator, and is simple in structure, and it is made up of dismounting baffle plate, nut, screw rod or bolt that the connection baffle plate that is provided with ear (branch two halves), two ends are respectively arranged with screw; Tool structure is very simple; The ear that connects baffle plate partly is provided with and is parallel to two screws that connect baffle plate, and the annulus edge that connects baffle plate two ear symmetry axis is provided with perpendicular to two screws that connect baffle plate, with two bolts the screw of two semicircular connection baffle plates through its ear part is linked together; Be connected with the connection baffle plate of ear at the screw that will pass dismounting baffle plate two ends with two bolts; The bolt low side is fixed with nut, and the centre is provided with hydraulic means, utilizes the pressure dismounting bearing of hydraulic means; Perhaps change hydraulic means into steel column or other subs, turn the bolt on both sides on the dismounting baffle plate, utilize the pulling force dismounting bearing of bolt.Easy to use and simple in structure being easy to carry of this frock; But after use in a short time, find that this frock need need support when using and just can dismantle below connecting plate, and connecting plate ear bolt and the bolt on the connecting plate partly can use unsatisfactory because of the stressed excessive distortion that causes.
The utility model content
The drawback that the utility model exists to above-mentioned existing wind-driven generator bearing removal work; A kind of double-fed wind power generator bearing combination dismounting frock is provided, when solving existing dismantlement work and using need be provided with below the connecting plate support just can dismantle with connecting plate on bolt can be because of the stressed excessive shortcoming of being out of shape of causing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of double-fed wind power generator bearing combination dismounting frock; Comprise dismounting baffle plate (2), connecting plate (4), connecting plate (4) is that the butt joint of two semi-rings forms, and is enclosed within the workpiece rotating shaft of workpiece bearing (8) below; Joint is outward extended with ear; Dismounting baffle plate (2) both sides connect auxiliary mould (5) through bolt or screw rod (3), and two auxiliary moulds (5) inboard is provided with jack (6), and the ear of said connecting plate (4) inserts in the jack (6); Between workpiece rotating shaft and the dismounting baffle plate (2) hydraulic means (9) or support column are set.
Said a kind of double-fed wind power generator bearing combination dismounting frock, said bolt or screw rod (3) are threaded with auxiliary mould (5).
Said a kind of double-fed wind power generator bearing combination dismounting frock, the internal diameter of said connecting plate (4) annulus is less than the external diameter of workpiece bearing.
The utility model compared with prior art has following beneficial effect: the insulating coating that can effectively protect bearing; Bearing removal is laborsaving, the bolt on the connecting plate since stressed excessive and can not cause the distortion, under the situation of no jack, also can work; Cost simple in structure is low, and reliability is high.
Description of drawings:
Fig. 1 is a kind of wind-driven generator auxiliary mould structural representation;
Fig. 2 is the auxiliary mould profile;
Fig. 3 is the auxiliary mould front view;
Fig. 4 is the auxiliary mould rearview;
Fig. 5 is the auxiliary mould vertical view;
Its Reference numeral: 1, nut, 2, the dismounting baffle plate, 3, screw rod, 4, connecting plate, 5, auxiliary mould, 6, jack, 7, screw, 8, bearing, 9, hydraulic means.
The practical implementation row:
To combine accompanying drawing below, the specific embodiment is done further to describe to the utility model.
A kind of double-fed wind power generator bearing combination dismounting frock; Comprise dismounting baffle plate (2), connecting plate (4), connecting plate (4) is that the butt joint of two semi-rings forms, and is enclosed within the workpiece rotating shaft of workpiece bearing (8) below; Joint is outward extended with ear; Dismounting baffle plate (2) both sides connect auxiliary mould (5) through bolt or screw rod (3), and two auxiliary moulds (5) inboard is provided with jack (6), and the ear of connecting plate (4) inserts in the jack (6); Between workpiece rotating shaft and the dismounting baffle plate (2) hydraulic means (9) or support column are set.Said bolt or screw rod (3) are threaded with auxiliary mould (5).The internal diameter of connecting plate (4) annulus is less than the external diameter of workpiece bearing.The utility model can effectively be protected the insulating coating of bearing; Bearing removal is laborsaving, and the bolt that has overcome connecting screw rod behind the connecting plate can be because of stressed excessive distortion, under the situation of the no jack inoperable shortcoming of can not causing; Cost simple in structure is low, and reliability is high.
The specific operation process of the utility model is: at first the butt joint of two semi-rings is formed connecting plate (4) and be enclosed within the workpiece rotating shaft of workpiece bearing (8) below; Ear with connecting plate inserts in the jack (6) of auxiliary mould (5) then; At last bolt or the screw of screw rod (3) through dismounting baffle plate (2) both sides are connected auxiliary mould (5), hydraulic means (9) or support column are set in the middle of the frock.
Embodiment one
The utility model device is installed on the bearing (8), and scheme of installation is as shown in Figure 1, with the pressure dismounting bearing of hydraulic means.
Embodiment two
Under the situation of no hydraulic means; Scheme of installation is as shown in Figure 1; On the basis of Fig. 1, change hydraulic means into one section steel column or other subs, an end withstands on the dismounting baffle plate (2), and the other end withstands on the axle; Twist the nut (1) at two ends, utilize the pulling force of screw rod (3) that bearing removal is got off.
Embodiment three
Scheme of installation is as shown in Figure 1; On the basis of Fig. 1, change nut (1) and screw rod (3) into bolt; Hydraulic means changes firm post or other subs into, and the bolt at two ends utilizes the pulling force of bolt that bearing removal is got off; But the degree of depth that will guarantee the screw (7) on the auxiliary mould (5) at this moment is greater than and turns the distance that bolt advances, and the bolt forward travel distance will guarantee to dismantle bearing.
