Description

The provision for disengagement of taper roll bearing outer ring

Technical field

The utility model relates to bearing extractor, more particularly, relates to the outer ring provision for disengagement of a kind of taper roll bearing.

Background technology

Taper roll bearing mainly is to bear based on footpath radially, axial connected load, and it extensively is applied to industries such as automobile, milling train, mine, metallurgy, plastics machinery.See also shown in Figure 1, the deflector roll 1 that shown in Figure 1 is on the rolling mill guiding device, these deflector roll 1 two ends all are equipped with taper roll bearing 2.Because in the operation of rolling, deflector roll 1 directly contacts with rolled piece, therefore wearing and tearing are inevitable.When the uniform wear amount reaches certain value, generally deflector roll 1 is done to scrap processing together with bearing 2.But, in rolling process, also often occurring because the problem of operation control or centering causes deflector roll 1 surface inordinate wear to occur, this moment, deflector roll 1 did not generally do to scrap processing, but carried out repairing and reusing.In repair process, impaired for fear of bearing outer ring 3, need when repairing, bearing outer ring 3 be taken out deflector roll.But, because this type of taper roll bearing outer ring 3 is less, outer ring 3 is pressed into the width a at step place in the deflector roll about 1.5mm, depth of groove b is about 3mm, the magnitude of interference is about 0.04mm, and therefore, dismounting is difficulty very, at present more existing common extracting tools all can't be realized conveniently dismantling, to the deflector roll reparation and again utilization bring difficulty.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides the outer ring provision for disengagement of a kind of taper roll bearing, and the taper roll bearing outer ring can be conveniently dismantled in this provision for disengagement.

For achieving the above object, the utility model adopts following technical scheme:

This taper roll bearing outer ring provision for disengagement comprises supporting plate, a pair of pusher dog and pair of bolts, has mounting hole in the middle of the supporting plate, and both sides have screw; Pusher dog is located in the mounting hole respectively; Pair of bolts is by passing the both sides that screw is divided into mounting hole.

Also be connected with an elastomeric element between the described a pair of pusher dog, this elastomeric element comprises spring base and the spring of being located on the spring base, and spring base is located on the pusher dog, and the spring other end and another pusher dog are fixed.

The bottom of described pusher dog is the drawing head that is inverted T-shaped, a drawing thickness of two sides difference.

Described bolt is a hexagon socket head cap screw.

This provision for disengagement also comprises a spanner in order to the rotation hexagon socket head cap screw, and spanner is connected at the upper end of hexagon socket head cap screw.

In technique scheme, taper roll bearing of the present utility model outer ring provision for disengagement comprises supporting plate, a pair of pusher dog and pair of bolts, has mounting hole in the middle of the supporting plate, and both sides have screw; Pusher dog is located in the mounting hole respectively; Pair of bolts is by passing the both sides that screw is divided into mounting hole.Adopt this provision for disengagement, simple in structure, easy to use, go deep in the deflector roll step place and block mutually by pusher dog with the bearing outer ring bottom, make by swivel bolt to produce a reverse top power between bolt and the deflector roll, the bearing outer ring drawing goes out deflector roll the most at last.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 2～shown in Figure 3, taper roll bearing of the present utility model outer ring provision for disengagement 10 comprises a supporting plate 11, a pair of pusher dog 12 and pair of bolts 13, have mounting hole 111 in the middle of this supporting plate 11, both sides have screw 112, screw 112 among Fig. 3 has two pairs, can be respectively applied for the bearing outer ring 3 of different-diameter, 13 of pair of bolts are by passing the both sides that screw 112 is divided into mounting hole 111.Above-mentioned pusher dog 12 is located at respectively in the mounting hole 111, and offsets by nut and mounting hole 111, and the bottom of each pusher dog 12 is the drawing 121 that is inverted T-shaped, and drawing 121 a thickness of two sides difference, is applicable to the degree of depth of steps in the different deflector rolls 1.Between this is to pusher dog 12, also be connected with an elastomeric element, this elastomeric element comprises spring base 14 and the spring of being located on the spring base 14 15, and spring base 14 is located on the pusher dog 12, and spring 15 other ends and another pusher dog 12 are fixing.Above-mentioned bolt 13 is a hexagon socket head cap screw, and this provision for disengagement 10 comprises a spanner 16 in order to rotation hexagon socket head cap screw 13, and spanner 16 is connected at the upper end of hexagon socket head cap screw 13.

Please in conjunction with shown in Figure 4, the former road of the work of this provision for disengagement 10 is as follows:

Earlier this is closed up along mounting hole 111 pusher dog 12, and in bearing outer ring 3, be inserted into step in the deflector roll 1; Decontrol pusher dog 12 then, pusher dog 12 is subjected to the elastic force of spring 15 to two side shiftings, thereby makes the drawing 121 of two pusher dogs 12 stretch into bearing outer ring 3 bottoms respectively, and blocks mutually with bearing outer ring 3 bottoms; Turn bolt 13 by spanner 16 again, make bolt 13 prop up deflector roll 1 end face, and produce a reverse top lift, rise, and go out deflector roll 1 by driving pusher dog 12 bearing outer ring 3 drawings the most at last of rising thereby drive supporting plate 11.

Adopt taper roll bearing of the present utility model outer ring provision for disengagement 10 can dismantle bearing outer ring 3 easily and fast, avoid bearing outer ring 3 impaired in deflector roll 1 is repaired, saved cost, brought economic benefit to enterprise.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
