Abstract
The utility model relates to a cavate includes quick dismantlement of deep groove ball bearing and grabs, including wrenching bar, lead screw, connect the disc, grapple pole, the wrenching bar cartridge can freely be loaded onto or lift off in the round hole that the lead screw tip was equipped with, the lead screw is connected through the screw that screw thread and connect the disc center were equipped with, four tip are established screwed grapple pole and are passed respectively behind four through -holes that the connect the disc circumference evenly was equipped with with the nut fastening connection together. Compared with the prior art, the beneficial effects of the utility model are that: simple structure, low cost can alleviate workman's intensity of labour, shorten repair time, guarantee that bearing box, main shaft do not damage because of dismantle many times, practice thrift the spare parts cost, have improved the equipment operation precision.
Description
Technical field
The utility model relates to hardware & tools technical field, particularly relates to a kind of cavate and includes deep groove ball bearing quick-detachment and grab.
Background technology
Environmental protection air blast is the equipment of the biological dephenolize aeration tank oxygen supply of certain grouping of the world economy work division department's environmental protection operation area sewage disposal, totally 8.When overhauling in the past at every turn and changed its deep groove ball bearing, because this deep groove ball bearing casing is cylindrical integral formula, and deep groove ball bearing position in casing is very dark, so be difficult to deep groove ball bearing directly to take out from casing, deep groove ball bearing and casing must be unloaded from main shaft with knocking the method for getting off in the lump during dismounting, waste time and energy, and easily cause the damage of deep groove ball bearing casing end face or box deformation damage consequently can not use.
Summary of the invention
For overcoming prior art defect, the technical problem that the utility model solves is to provide a kind of cavate and includes deep groove ball bearing quick-detachment and grab, structure is simple, with low cost, the labour intensity of workman can be alleviated, shorten the repair time, guarantee bearing housing, main shaft do not damage because repeatedly dismantling, and save standby redundancy cost, improve equipment operation precision.
In order to achieve the above object, the utility model realizes by the following technical solutions:
Cavate includes deep groove ball bearing quick-detachment and grabs, and comprises wrenching bar, leading screw, clutch disk, grapple bar, it is characterized in that, described wrenching bar is inserted in the circular hole that leading screw end is provided with, and can freely load onto or unload; The screw that described leading screw is provided with by screw thread and clutch disk center is connected; Link together with fastening nuts after establish threaded grapple bar to be each passed through four through holes that clutch disk even circumferential is provided with of described four ends.
The other end of described grapple bar is provided with the gib head with deep groove ball bearing raceway form fit, and middle front part is provided with 90 ° of sign of rotations.
Compared with prior art, the beneficial effects of the utility model are:
1) improve labor productivity, original each upkeep operation needs pincers worker 8 people, frame work 2 people, operation 16 hours, and after using this device, service work only needs pincers worker 6 people, operation 4 hours;
2) improve equipment operation precision, overcome over and often dismantle deep groove ball bearing casing, during installation, contraposition is incorrect causes the undesirable elements such as body vibration;
3) save standby redundancy cost, past operation often causes deep groove ball bearing casing end face to damage or deep groove ball bearing damages, and now uses this device to operate, can accomplish that neither damaging deep groove ball bearing does not damage deep groove ball bearing casing yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model works state.
In figure: 1-wrenching bar 2-leading screw 3-clutch disk 4-grapple bar 5-axle 6-deep groove ball bearing
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1, the utility model relates to cavate and includes deep groove ball bearing quick-detachment and grab, and comprises wrenching bar 1, leading screw 2, clutch disk 3, grapple bar 4, and described wrenching bar 1 is inserted in the circular hole that leading screw 2 end is provided with, and can freely load onto or unload; The screw that described leading screw 2 is provided with by screw thread and clutch disk 3 center is connected; Link together with fastening nuts after establish threaded grapple bar 4 to be each passed through four through holes that clutch disk 3 even circumferential is provided with of described four ends.
The other end of described grapple bar 4 is provided with the gib head with deep groove ball bearing raceway form fit, and middle front part is provided with 90 ° of sign of rotations.
Operation principle:
1) four grapple bars 4 stretch in bearing housing, insert in the raceway of the inner-outer sleeve of deep groove ball bearing 6, clamp 90 ° of sign of rotation place half-twists, make the special gib head in grapple bar 4 end firmly be stuck in deep groove ball bearing 6 raceway with adjustable wrench;
2) with nut by fastening to hook pull bar 4 and clutch disk 3;
3) adjusting screw 2 makes its end withstand the end of axle 5;
4) insert rotational lead screw 2 in leading screw 2 with wrenching bar 1, spiral force is delivered to grapple bar 4 by clutch disk 3 and forms axial tension, then be delivered to deep groove ball bearing 6 by grapple bar 4 end gib head; Under this responsive to axial force, clutch disk 3, grapple bar 4 drive deep groove ball bearing 6 together outwards movement deep groove ball bearing 6 can be unloaded.
Claims (2)
