Abstract
The utility model discloses an electromagnetic force obtaining clutch structure. According to the electromagnetic force obtaining clutch structure, due to the fact that axial force borne by working parts can be shared and reduced, the working parts can not be damaged easily. The electromagnetic force obtaining clutch structure overcomes the defect that according to an existing electromagnetic clutch, due to the fact that the axial force generated by the electromagnetic clutch is mainly borne by working parts, the working parts can be damaged easily. The electromagnetic force obtaining clutch structure comprises a clutch base and a magnetic ring, wherein a belt pulley which is connected with the magnetic ring in a rotating mode is arranged on the magnetic ring, a clutch sucker is arranged on one side of the belt pulley and is connected with a force obtaining shaft which is used for driving a gear pump, the force obtaining shaft penetrates through the clutch base, a boss protruding towards the force obtaining shaft is arranged on the clutch base, and two angular contact bearings are arranged on the force obtaining shaft. The electromagnetic force obtaining clutch structure can be applied to occasions where the existing electromagnetic clutch is used and has the advantages that the axial force and radial force can be well borne, the friction of a belt is strong, and working stability of the belt pulley is high.

China Patent Publication No. CN201306399Y, open day on September 9th, 2009, the name of model utility is called magnetic clutch, this application case discloses a kind of magnetic clutch, its electromagnetic coil is fixed on adjacent casing by coil brace, and electromagnetic coil and transmission shaft radially be provided with gap, avoided iron filings, slag particles to assemble the electromagnetic coil that may cause between electromagnetic coil and transmission shaft servo-actuated.This model utility deficiency is, when producing axial force, almost completely by workpieces such as output shafts, is born, and easily causes the damage of magnetic clutch workpiece.
The model utility content
The utility model is mainly born by workpiece while having overcome existing magnetic clutch generation axial force, cause the flimsy deficiency of workpiece, provide a kind of and can share and subdue therefore non-damageable electromagnetism force aid clutch structure of the axial force of bearing on workpiece.
The utility model is achieved through the following technical solutions:
A kind of electromagnetism force aid clutch structure, comprise clutch base, the magnetic circle, described magnetic circle is provided with the belt pulley be rotationally connected with the magnetic circle, described belt pulley one side is provided with the clutch sucker, described clutch sucker connects the power taking axle for the driven gear pump, described power taking axle is through clutch base, described clutch base is provided with the boss risen towards the power taking crown of roll, described power taking axle is provided with two angular contact bearings, angular contact bearing near clutch sucker one side is between clutch sucker and boss, angular contact bearing away from clutch sucker one side is between the output terminal and boss of power taking axle.Belt pulley is by the belt driven rotary, and when work, clutch sucker and belt pulley adhesive are integral running, and reverse the driven gear pump work by the power taking axle, when sucker, not during adhesive, angular contact bearing is mainly in order to support clutch base, power taking axle, bearing radial force; After the adhesive of clutch sucker, angular contact bearing is auxiliary bears axial force, plays the effect of protection power taking axle, clutch sucker, prevents that the workpiece such as power taking axle is stressed excessive at single place, guarantees the working life of magnetic clutch.
As preferably, be provided with spacer between described angular contact bearing, described spacer is looped around on the power taking axle.Utilize spacer rationally to control two distances between angular contact bearing, maintain stable working state.
As preferably, described power taking axle is provided with keyway, in described keyway, is provided with for connecting the flat key of power taking axle and clutch sucker.Utilize the connection between keyway and flat key strengthening power taking axle and clutch sucker, improve integrally-built stability.
As preferably, described clutch base is provided with circlip for shaft, described circlip for shaft at the clutch sucker during in attracting state and the magnetic circle be affixed.When the adhesive of clutch sucker, circlip for shaft can prevent that the miscellaneous part on magnetic circle and clutch base from directly bumping against, and plays a protective role.
As preferably, described belt pulley is provided with the belt corresponding with belt pulley, and described belt is the 4PK belt.The 4PK belt is exactly four groove belts, with ordinary straps and vee-belt, compares, and its frictional force is stronger, has better performance, can more stably be with movable strap disc to rotate.
Therefore, the beneficial effects of the utility model are: (1) angular contact bearing is auxiliary bears axial force and radial force, and workpiece is not fragile; (2) use the 4PK belt, frictional force is strong, and during the work of band movable strap disc, stability is high.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: clutch base 1, magnetic circle 2, belt pulley 3, clutch sucker 4, power taking axle 5, boss 6, angular contact bearing 7, spacer 8, flat key 9, circlip for shaft 10.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of electromagnetism force aid clutch structure as shown in Figure 1, comprise clutch base 1, magnetic circle 2, described magnetic circle 2 is provided with the belt pulley 3 be rotationally connected with magnetic circle 2, described belt pulley 3 one sides are provided with clutch sucker 4, the power taking axle 5 that described clutch sucker 4 connects for the driven gear pump, described power taking axle 5 is through clutch base 1, described clutch base 1 is provided with towards the boss 6 of power taking axle 5 projections, described power taking axle 5 is provided with two angular contact bearings 7, angular contact bearing 7 near clutch sucker 4 one sides is between clutch sucker 4 and boss 6, angular contact bearing 7 away from clutch sucker 4 one sides is between the output terminal and boss 6 of power taking axle 5.Be provided with spacer 8 between described angular contact bearing 7, described spacer 8 is looped around on power taking axle 5.Utilize spacer 8 rationally to control two distances between angular contact bearing 7, maintain stable working state.Described power taking axle 5 is provided with keyway, in described keyway, is provided with for connecting the flat key 9 of power taking axle 5 and clutch sucker 4.Utilize the connection between keyway and flat key 9 strengthening power taking axles 5 and clutch sucker 4, improve integrally-built stability.Described clutch base 1 is provided with circlip for shaft 10, described circlip for shaft 10 at clutch sucker 4 during in attracting state and magnetic circle 2 be affixed.When 4 adhesive of clutch sucker, circlip for shaft 10 can prevent that magnetic circle 2 and the miscellaneous part on clutch base 1 from directly bumping against, and plays a protective role.Described belt pulley 3 is provided with the belt corresponding with belt pulley 3, and described belt is the 4PK belt.The 4PK belt is exactly four groove belts, with ordinary straps and vee-belt, compares, and its frictional force is stronger, has better performance, can more stably be with movable strap disc 3 to rotate.In addition, boss 6 is provided with three dismounting grooves, is convenient to the dismounting of angular contact bearing 7.
