Description
Technical field
The present invention relates to and dial cover device, particularly relating to group cover device for dismantling rolling bearing dust cover.
Background technology
Rolling bearing is the widely used universal or special parts of a lot of enterprise, is arranged on the rolling bearing in transmission case bearing block for some, after some time of use, must regularly overhaul it, clean or refuel.It normally works to enter rolling bearing internal influence for preventing extraneous dust or foreign material, comparatively large, that price the is more expensive rolling bearing of some appearance and sizes all installs metal dust cover, this part is generally metal crimp shaped piece, be arranged on the interior backstop position of housing washer in an interference fit, therefore, before rolling bearing being overhauled, clean or refuels, first dust cover must be moved back and unload down, then the inside and outside circle, roller, retainer etc. of rolling bearing could be decomposed one by one.And decomposed each is cleaned, overhauls, change and add the work such as lubricating grease.And the practice of present enterprise normally decomposes dust cover with crowbar, this method is required great effort and is easy to damage dust cover very much, even can cause the damage of other parts of rolling bearing thus cause scrapping of whole rolling bearing, causing larger economic loss also to have impact on the overall service work progress of equipment.
Summary of the invention
The technical problem to be solved in the present invention is group cover device not being specifically designed to dismounting rolling bearing dust cover, usually use crowbar to decompose dust cover when dismantling the dust cover of rolling bearing, efficiency is low and easily damage rolling bearing and dust cover, provides a kind of easy to use and do not have prejudicial group of cover device to rolling bearing and dust cover for this reason.
Technical scheme of the present invention is: a kind ofly dial cover device for what dismantle rolling bearing dust cover, and it comprises lower end has the round table-like hollow cover for seat of annular stopper, center is pressed with T-nut gland, pusher dog, fairlead, bearing block, taper roll bearing, T-shaped screw rod and rotates handwheel; In described cover for seat, end face center has central through hole, bearing block adaptation wherein, in cover for seat, end face is also evenly equipped with 3 secondary through holes, described secondary through hole is pressed with fairlead, in cover for seat, adaptation has gland, and in the T-nut at described gland center and cover for seat, the central through hole of end face is suitable, and the top disc of gland is provided with 3 through holes suitable with the fairlead of end face in cover for seat, described pusher dog is stretched in cover for seat by gland through hole and fairlead, and is fixed on gland; In described bearing block, adaptation has taper roll bearing, and described T-shaped screw rod fits in T-nut and side, bottom fits on taper roll bearing, is connected with and makes T-shaped screw rod and tight baffle ring below described taper roll bearing.T-shaped screw rod upper end is connected with rotation handwheel.
Pusher dog described in such scheme comprises pusher dog spanner from top to bottom, divide with gland through hole and the suitable cylindrical pilot of fairlead internal diameter and L-type claw hook for hooking rolling bearing dust cover, and the cylindrical pilot of described pusher dog divides the part be exposed at outside gland to be fixed on gland by nuts and washers.
Taper roll bearing described in such scheme is fitted in bearing block by axle sleeve and circlip for hole.
The invention has the beneficial effects as follows the anchor ring being blocked the dust cover of workpiece by adjustment pusher dog, the annular stopper of cover for seat is enclosed within the outer ring of workpiece, when rotating handwheel, pusher dog drives the anchor ring of dust cover to move upward, the annular stopper of cover for seat drives workpiece to move downward the separation realizing dust cover, structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is that the present invention uses schematic diagram;
In Fig. 2,1 is cover for seat, and 2 is pusher dogs, and 3 is fairleads, and 4 is nuts, and 5 is packing rings, 6 is rotate handwheel, and 7 is glands, and 8 is T-nut, and 9 is T-shaped screw rods, and 11 is circlip for holes, 12 is taper roll bearings, and 13 is axle sleeves, and 14 is baffle rings, and 15 is pusher dog spanners, and 16 is bearing blocks.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention includes that lower end has the round table-like hollow cover for seat 1 of annular stopper, bearing block 16, fairlead 3, center are pressed with gland 7, pusher dog 2, taper roll bearing 12, the T-shaped screw rod 9 of T-nut 8 and rotate handwheel 6; In described cover for seat 1, end face center has central through hole, bearing block 16 adaptation wherein, in cover for seat 1, end face is also evenly equipped with 3 secondary through holes, described secondary through hole is pressed with fairlead 3, in cover for seat 1, adaptation has gland 7, and the T-nut at described gland 7 center 8 is suitable with the central through hole of end face in cover for seat, and the top disc of gland 7 is provided with 3 through holes suitable with the fairlead 3 of end face in cover for seat 1, described pusher dog 2 is stretched in cover for seat 1 by gland through hole and fairlead 3, and is fixed on gland 7; In described bearing block 16, adaptation has taper roll bearing 12, and described T-shaped screw rod 9 fits in T-nut 8 and side, bottom fits on taper roll bearing 12, is connected with and makes T-shaped screw rod 9 and tight baffle ring 14 below described taper roll bearing 12.T-shaped screw rod 9 upper end is connected with rotates handwheel 6.
The preferred pusher dog of the present invention 2 comprises pusher dog spanner 15 from top to bottom, divide with gland through hole and the suitable cylindrical pilot of fairlead 3 internal diameter and L-type claw hook for hooking rolling bearing dust cover, and the cylindrical pilot of described pusher dog 2 divides the part be exposed at outside gland 7 to be fixed on gland by nut 4 and packing ring 5.Described taper roll bearing 12 is fitted in bearing block 16 by axle sleeve 13 and circlip for hole 11.
