Technical field
The utility model relates to the dust cover pressing device, relates 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 installed in rolling bearing in the transmission case bearing block for some, after use after a while, must regularly overhaul, clean or refuel it.For preventing that extraneous dust or foreign material from entering its normal operation of rolling bearing internal influence, some appearance and sizes rolling bearing large, that price is more expensive is all installed the metal dust cover, this part is generally metal die spare, be installed in the interior backstop position of housing washer in the mode of interference fit, therefore, before rolling bearing being overhauled, cleans or refuel, at first dust cover must be moved back and unload down, then the inside and outside circle of rolling bearing, roller, retainer etc. could be decomposed one by one.And each part that decomposes cleaned, overhauls, changes and add the work such as lubricating grease.In the decomposition of finishing each part of rolling bearing, maintenance, after grease-added, need it is assembled, and dust cover normally in the end one assembling procedure finish assembling, at present, enterprise with good conditionsi adopts special-purpose rolling bearing dust cover pressing machine to finish the assembling of dust cover at workshop usually, but the Large-Scale Equipment rolling bearing for some field works, when breaking down, rolling bearing just can't finish at the scene the work that press-fits of dust cover in the time of need rushing to repair it with corresponding special-purpose press-loading device, in addition, some do not have the enterprise of special-purpose rolling bearing dust cover pressing machine normally to draw horse and corresponding aid to finish this installment work by experienced erector's utilization, namely waste time and energy and fragile dust cover, even thereby the damage that can cause other parts of rolling bearing causes scrapping of whole rolling bearing, causes larger economic loss also to affect the whole service work progress of equipment.
The utility model content
The technical problems to be solved in the utility model 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 that is used for rolling bearing that is not subjected to the place restriction is provided for this reason.
The technical solution of the utility model is: a kind of rolling bearing dust cover pressing device, it comprises base, locking nut, double threaded screw, the screw rod mount pad, T-shaped screw rod, the positioning and guiding cover, the annular gland, three-jaw pressure head and press-fit handwheel, described base upper end is provided with the seam that can carry the rolling bearing excircle part, its inside is provided with stepped round platform, the round platform center is provided with the through hole that can supply double threaded screw to stretch into, the lower end of described double threaded screw is fixed on the 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 the 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 of described three-jaw pressure head is adaptive annular gland, described annular gland is outward extended with seam, the outside adaptive positioning and guiding cover that has under the seam of annular gland, 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 beneficial effects of the utility model are simple in structure convenient mobile, only need rotate during use and press-fit handwheel and push down the three-jaw pressure head annular gland is moved down along the positioning and guiding cover, after the cylindrical seam of annular gland and positioning and guiding put end contact, dust cover is fitted in the appointed part of housing washer endoporus, and is easy to operate.
