Abstract
The utility model discloses a kind of chemical pump rolling bearing dismounting frock, comprise dismounting dish and dismounting disk, be connected by long bolt between described dismounting dish with dismounting disk, described dismounting disk offers and ejects hole, in the disc face of described dismounting disk protrude be provided with threaded post, described threaded post be internal thread arrange, described dismounting dish offers wear for long bolt wear mouth, one end of described long bolt is fixed in threaded post, and the other end is arranged in wearing in mouth of dismounting dish.The utility model gives prominence to effect: can carry out easily and fast to the dismounting of chemical pump rolling bearing, and can well protect bearing injury-free.
Description
Technical field
The utility model relates to a kind of disassembling fixture, particularly relates to a kind of chemical pump rolling bearing dismounting frock.
Background technology
Due to mechanical requirements between the bearing of chemical pump and axle, be generally interference fit, so bearings mounted time, the general mode adopting heating bearing, is arranged on bearing on axle.But it is cumbersome when dismantling that this interference fit causes bearing, meanwhile, the damage that improper meeting causes the rear pump bearing of dismounting if dismantle, thus increase maintain and replace cost.
Existing rolling bearing disassembling fixture is by three-pawl type drawbench.Primarily of three pulling claws and mechanical screws (or hydraulic pressure) mechanism composition.Be fixed on the outer shroud place of bearing by three pulling claws, then screw rod (or hydraulic pressure) mechanism withstood on spindle nose end in advance, screw screw rod (or pressurization) and bearing is pulled up from axle pull-up.But due to pulling claw with can only be fixed on the outer shroud of bearing.Due to the structure of bearing, this Hubbing method is easy to brokenly the retainer of collar bearing body or bearing, causes bearing to scrap, and can not use.Thus cause the waste in company cost and the consumption in man-hour.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of chemical pump rolling bearing dismounting frock.
The purpose of this utility model, will be achieved by the following technical programs:
Chemical pump rolling bearing dismounting frock, comprise dismounting dish and dismounting disk, be connected by long bolt between described dismounting dish with dismounting disk, described dismounting disk offers and ejects hole, in the disc face of described dismounting disk protrude be provided with threaded post, described threaded post be internal thread arrange, described dismounting dish offers wear for long bolt wear mouth, one end of described long bolt is fixed in threaded post, and the other end is arranged in wearing in mouth of dismounting dish.
Preferably, described dismounting disk cross section is the shape of a hoof, and during dismounting, the disc face of described dismounting disk abuts with bearing internal external ring, and described dismounting dish cross section is rhombus.
Preferably, described threaded post is arranged at the two ends of disc face respectively, described in wear the two ends that mouth is arranged at dismounting dish respectively, described in wear mouth cross section be strip.
The utility model gives prominence to effect: can carry out easily and fast to the dismounting of chemical pump rolling bearing, and can well protect bearing injury-free.Laborsavingly to save time, indirectly save dismounting and change cost.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As Fig. 1, the utility model discloses a kind of auxiliary mould for the dismounting of chemical pump rolling bearing, comprises dismounting dish 2 and dismounting disk 1.Highly preferred embodiment, considers from volume and weight, and described dismounting disk 1 cross section is the shape of a hoof, and it is rhombus that 1 cross section is coiled in described dismounting.Certainly, adopting other structure, is square if dismounting disk cross section is annulus or dismounting dish.
Be connected by long bolt 3 between described dismounting dish 2 with dismounting disk 1.Concrete, described dismounting disk 1 offers and ejects hole 12.The two ends of the disc face of described dismounting disk 1 are protruded and is provided with threaded post 11, described threaded post 11 is internal thread setting.Accordingly, described dismounting dish 2 offers the cross section worn for long bolt 3 be strip wear mouth 21, one end of described long bolt 3 is fixed in threaded post 11, and the other end is arranged in wearing in mouth 21 of dismounting dish 1.During dismounting, the disc face of described dismounting disk 1 abuts with bearing internal external ring.
The below lower dismounting principle of the present utility model of summary:
By frock of the present utility model, rolling bearing to be removed is fixed, make the inner and outer ring of the disc face laminating bearing dismantling disk, avoid contact bearing body and retainer, simultaneously, one end of rolling bearing props up liftout attachment, one end of described liftout attachment abuts with dismounting dish, and described liftout attachment is hydraulic jack.Regulate the distance between dismounting disk and dismounting dish by long bolt, axle is got off from drawing in bearing by the hole 12 that ejects of dismounting disk by jack.Need to set forth, in actual applications, dismounting dish is oppositely arranged with dismounting disk transverse direction, and dismounting dish lifts by hanging apparatus, and this is not as the structure of this frock.
Can be dismantled very easily by this frock dismounting rolling bearing, and unnecessary damage can not be caused to bearing, practical.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
