The utility model provides a bearing extracting tool is rational in infrastructure, utilizes its dismantlement bearing to save time and saves labour, can effectively improve work efficiency, has fine result of use to part around the injury in the time of preventing to dismantle the bearing.
Description
Technical field
The utility model relates to a kind of bearing extractor of corona roller, belongs to bearing extractor structure-design technique field.
Background technology
In polypropylene film production line, to need after longitudinal stretching and cross directional stretch from slab machine sheet film out and formed the polypropylene film of finished product by subsequent handling (sided corona treatment, entangle limit, cut, rolling and packaging etc.).Polypropylene film, when sided corona treatment, can produce electrostatic, and then can damage the ball on bearing, causes bearing damage, therefore needs regularly to change bearing.The bearing mounted configuration of corona roller as shown in Figure 1, on roller shaft 4, cover has locking axle sleeve 5 (having axial short slot), the outer surface of described locking axle sleeve 5 has certain taper, and be provided with external screw thread in thinner Ye Ji outer end, one end, bearing 6 to be set on described locking axle sleeve 5 and by locking with the locking nut 7 of described external screw thread threaded engagement, thus locking axle sleeve 5, bearing 6 is locked together with roller shaft 4.Existing bearing removal method is, locking nut 7 and corresponding pad 8 are pulled down rear tup and outwards knocks bearing 6, make bearing 6 slowly from slippage locking axle sleeve 5, bearing is time-consuming takes a lot of work to adopt above-mentioned existing method to dismantle, efficiency is very low, and careless slightlyly when beaing bearing also can injure side parts.
Utility model content
To this, the utility model aims to provide a kind of bearing extractor being convenient to the corona roller of bearing removal.
The technical scheme realizing the utility model object is:
A bearing extractor for corona roller, comprises keeper, external member and bolt assembly; Described keeper is connected with described external member by some bolt assemblies, described keeper is circular laminated structure, be suitable for being enclosed within roller shaft and also can offset with the outer face of locking axle sleeve, described external member is annulus laminated structure, is suitable for being enclosed within roller shaft also can moving towards keeper when tightening described bolt assembly and offseting with the side of bearing away from described keeper.
In technique scheme, described external member comprises two folded collars be located at together, and each collar is formed by the nest plate of two semi-ring sheets is involutory, and staggers in the involutory gap on two collars.
In technique scheme, the involutory gap on two collars is perpendicular.
In technique scheme, the quantity of described bolt assembly is four, circumferentially uniform setting.
The utility model has positive effect: (1) this bearing extractor in use, first the nut on locking axle sleeve and corresponding pad are removed, then described keeper is inserted in from roller shaft free end, described external member to be socketed on described roller shaft described bearing away from the side of described keeper, then clamp nut or the fastening bolt of bolt assembly is screwed, the outer face that described keeper can be against locking axle sleeve can be ordered about described external member and moved near described keeper direction, described external member can produce axially outside active force to bearing in the process of movement, thus make bearing from slippage locking axle sleeve, adopt this extracting tool dismantle bearing time comparatively convenient, time and labour saving, can effectively increase work efficiency, and injury peripheral parts when can prevent dismounting bearing.(2) in extracting tool of the present utility model, external member comprises two collars, and two collars are made up of two involutory semi-ring sheet nest plates, arrange structure like this to simplify, and external member can be facilitated to install, arrange two involutory gaps to stagger and can effectively ensure external member can effectively form closed Annular trepanning, guarantee functional reliability.

Detailed description of the invention
Do to illustrate to the concrete structure of the bearing extractor of corona roller in the utility model below in conjunction with Figure of description:
A bearing extractor for corona roller, as shown in Figure 2, it comprises keeper 1, external member 2 and bolt assembly 3; Described keeper 1 is connected with described external member 2 by some bolt assemblies 3, described keeper 1 is in being suitable for being enclosed within roller shaft 4 and the circular laminated structure that can offset with the outer face of locking axle sleeve 5, and described external member 2 is in being suitable for being enclosed within roller shaft 4 and the annulus laminated structure that can offset away from the side of described keeper 1 with bearing 6.The bearing extractor of the present embodiment in use, first the nut on locking axle sleeve 5 and corresponding pad are removed, then by described keeper 1 from roller shaft free end cover, described external member 2 to be socketed on described roller shaft 4 described bearing 6 away from the side (as shown in Figure 3) of described keeper 1, then clamp nut or the fastening bolt of bolt assembly 3 is screwed, the outer face that described keeper 1 can be against locking axle sleeve 5 can be ordered about described external member 2 and moved near described keeper 1 direction, described external member 2 can produce axially outside active force to bearing 6 in the process of movement, thus make bearing 6 from slippage locking axle sleeve 5, adopt this extracting tool dismantle bearing time comparatively convenient, time and labour saving, can effectively increase work efficiency, and injury peripheral parts when preventing dismounting bearing.
In the present embodiment, described external member 2 comprises two folded collars 21 be located at together, and each collar 21 is formed by the nest plate 22 of two semi-ring sheets is involutory, and staggers in the involutory gap on two collars 21, and structure as shown in Figure 4; In this extracting tool, external member 2 arranges rational in infrastructure, and external member 3 can be facilitated to install, and arranges two involutory gaps and staggers and can effectively ensure external member 2 can effectively form closed Annular trepanning, guarantee functional reliability.Further, the involutory gap on two collars 21 is perpendicular, and as the distressed structure of above-mentioned external member, in practical operation, described each collar 21 also can be formed by the nest plate 22 of three arc line shapeds is involutory.
The quantity of the described bolt assembly 3 in the present embodiment is four, circumferentially uniform setting, arranges like this and can ensure result of use, in practical operation under the prerequisite reducing bolt assembly 3 quantity, keeper 1 and external member 2 can arrange many and 4 bolt hole, in order to selecting.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
