Description
Technical field
The present invention relates to dust cover pressing device, relate in particular to the dust cover pressing device for rolling bearing.
Background technology
Rolling bearing is the widely used universal or special parts of a lot of enterprises, is arranged on the rolling bearing in transmission case bearing block for some, after use after a while, must regularly it be overhauled, be cleaned or refuel.In order to prevent extraneous dust or foreign material from entering rolling bearing internal influence, it is normally worked, some appearance and sizes rolling bearing large, that price is more expensive is all installed metal dust cover, this part is generally metal die part, be arranged on the interior backstop position of housing washer in the mode of interference fit, therefore, before rolling bearing being overhauled, is cleaned or refuel, first dust cover must be moved back and unloads down, then the inside and outside circle of rolling bearing, roller, retainer etc. could be decomposed one by one.And clean, overhaul, change and add the work such as lubricating grease to decomposed each.In the decomposition completing each of rolling bearing, maintenance, after grease-added, need assemble it, and dust cover normally in the end one assembling procedure complete assembling, at present, enterprise with good conditionsi adopts special rolling bearing dust cover pressing machine to complete the assembling of dust cover at workshop conventionally, but for the Large-Scale Equipment rolling bearing of some field works, when breaking down, rolling bearing just cannot complete at the scene the work that press-fits of dust cover need rush to repair it time with corresponding special press-loading device, in addition, some do not have the enterprise of special rolling bearing dust cover pressing machine normally to utilize and draw horse and corresponding aid to complete this installment work by experienced erector, waste time and energy and fragile dust cover, thereby the damage that even can cause other parts of rolling bearing causes scrapping of whole rolling bearing, cause larger economic loss also to affect and equip overall service work progress.
Summary of the invention
The technical problem to be solved in the present invention is that the apparatus for assembling position of existing rolling bearing dust cover is fixed, is inconvenient to transport and carries, and a kind of dust cover apparatus for assembling for rolling bearing that is not subject to place restriction is provided for this reason.
Technical scheme of the present invention is: a kind of rolling bearing dust cover pressing device, it comprises base, locking nut, double threaded screw, screw rod mount pad, T-shaped screw rod, positioning and guiding cover, annular gland, three-jaw pressure head and press-fit handwheel, described base upper end is provided with the seam that can carry rolling bearing excircle part, its inside is provided with stepped round platform, round platform center is provided with the through hole that can stretch into for double threaded screw, the lower end of described double threaded screw is fixed on base by locking nut, the upper end of double threaded screw and screw rod mount pad are suitable, the upper end of described screw rod mount pad is connected with three-jaw pressure head by T-shaped screw rod, described three-jaw pressure head upper end is connected with and press-fits handwheel, three-jaw pressure head bottom is provided with the round platform with equally distributed 3 paws, the round platform outer surface adaptation of described three-jaw pressure head has annular gland, described annular gland is outward extended with seam, under the seam of annular gland, outside adaptation has positioning and guiding cover, described positioning and guiding cover lower end is provided with the annular stopper suitable with housing washer.
The improvement of such scheme is that described positioning and guiding puts end face bottom and is provided with annular groove.
The invention has the beneficial effects as follows simple in structure convenient mobile, when use, only need rotate and press-fit handwheel and push down three-jaw pressure head annular gland is moved down along positioning and guiding cover, when cylindrical seam and the positioning and guiding of annular gland put after end contact, dust cover is fitted in the appointed part of housing washer endoporus, easy to operate.
