Abstract
The utility model discloses a novel double outer ring conical surface locking plate, which comprises an outer ring and an inner ring, wherein the outer ring adopts the double outer rings which are sleeved in an inserting way and matched, and the corresponding matching surface between the outer ring I and the outer ring II of the double outer ring is an interference fit conical surface with a rakeangle. The utility model adopts the scheme that because conical surface pre-tension match is arranged between the two outer rings, the pre-tension force can be adjusted through the rake angle Beta andthe compression travel H, the locking force of the locking plate can be enhanced, and the security and reliability are high.
Description
Technical field
The utility model relates to mechanical hitch bar technical field, especially a kind of novel two outer annular conical surface locking plates.
Background technique
Usually locking plate is made up of outer shroud, interior ring and bolt, and the outer shroud endoporus is made two step conical surfaces, and the outer fenestra of interior ring is made two step conical surfaces, two conical surfaces of interior ring and two conical surface contact matching of outer shroud, and be coated with lubricating grease between the conical surface.Outer shroud step place is shaped on a plurality of screw holes along circumference, and the opposite position of interior ring also is shaped on the filament hole of equal amount.Locking plate installs to the transmission connection piece that is locked---on axle and the axle sleeve, ring forms the wedging relation in the locking plate between axle sleeve and outer shroud, after tighting a bolt one by one by the moment of setting, in axle sleeve, produce a positive pressure between the cylindrical of circle and axle, because the existence of positive pressure when axle rotates, can produce stiction between axle and axle sleeve, when moment of torsion that driving torque can provide smaller or equal to stiction, promptly realized effective moment of torsion transmission.And the size of stiction depends primarily on the size of positive pressure after the material of axle and axle sleeve is determined, positive pressure is big more, and stiction is big more, and the moment of torsion that system can transmit is also big more.Therefore, increase positive pressure, must increase the coupling mechanism force of locking plate, and the size of coupling mechanism force depends primarily on the hoop tensile stress that the locking plate outer shroud can bear.The structure of existing locking plate since the restriction of outer ring material and structure make and increase coupling mechanism force again and be restricted, if do not change the suffered stress distribution of outer ring structure and outer shroud, can cause the suffered stress of outer shroud to exceed the stress that outer ring material can bear and continue to increase coupling mechanism force, make the outer ring material of locking plate that surrender and cracking take place, cause locking to lose efficacy, produce between axle and the axle sleeve and skid, make transmission failure, severe patient generation security incident.
The model utility content
The purpose of this utility model provides a kind of novel two outer annular conical surface locking plates, can improve coupling mechanism force, Security and the reliability height of locking plate.
The technical solution of the utility model is: a kind of novel two outer annular conical surface locking plates, comprise outer shroud, interior ring, and described outer shroud is two outer shrouds that sleeve cooperates, the outer shroud I of described pair of outer shroud and outer shroud II corresponding matching face are the interference fit conical surface that has draft angle.
Described outer shroud I and outer shroud II be not subjected to force compresses form overall structure before and sleeve when being bonded to the bosom leaves compression stroke between the same side end face of two outer shrouds vertically.
The utility model is divided into two bodies with outer shroud, and form self-locking by conical surface pretension, locking plate outer shroud and internal surface thereof are pre-formed the hoop compressive stress state, it is hoop tensile stress negative value, make the suffered tensile stress of outer shroud balanced out a part, improved the stress distribution of outer shroud greatly, significantly reduced the hoop tensile stress peak value of outer ring inner surface by the stress negative value, improved the Security and the reliability of locking plate self greatly, the bulk strength of outer shroud also is significantly improved.Under the ring diameter same case, compare with existing locking plate outside, the utility model can provide bigger moment of torsion.
The utility model is owing to be made as the pre-drive fit of the conical surface with two outer shrouds, and it is easy to have technology, good to neutrality, workable, and pretightening force can adjust by draft angle β and compression stroke H, so, carry out the accurate Calculation and the design of pretightening force for the artificer and provide convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the view before outer shroud II of the present utility model is pressed into outer shroud I;
Fig. 3 is the view after outer shroud II of the present utility model is pressed into outer shroud I self-locking close-fitting.
Embodiment
As Fig. 1,2, shown in 3, the utility model is mainly by outer shroud I1, outer shroud II2, compositions such as interior ring 3 and bolt 4, outer shroud I1 is by cooperating the conical surface 5 pretension interference fit joint on outer shroud II2, self-locking is an one, form and be with interior ring 3 in the whole outer shroud, in ring 3 be connected on the step surface of outer shroud II2 by several high-strength bolts 4 by boss, the cylindrical of interior ring 3 is the cone that has gradient, the outer fenestra of the boss of interior ring 3 has gradient in the same way, form whole outer shroud endoporus for interior ring 3 taper hole of gradient in the same way to be arranged, the step place endoporus of whole outer shroud also has gradient in the same way.Because outer shroud I1 and outer shroud II2 cooperate the conical surface 5 to form the pretension self-locking structure, the endoporus that is outer shroud I1 is made as gradient taper hole, the cylindrical of outer shroud II2 is made as the cone of gradient in the same way with outer shroud I1, so draft angle β must less than outer ring material from the locking angle, be β＜arctg μ, μ is the friction factor between outer shroud I1 and the outer shroud II2, and this friction factor can be found by relevant handbook, or data obtain by experiment; Outer shroud I and outer shroud II should leave compression stroke H between the end face that forms two outer shrouds before the overall structure, compression stroke H can calculate according to the value of draft angle β and the pretightening force of setting.
The utility model should be pressed into outer shroud I1 with outer shroud II2 earlier, becomes the one of interference fit by conical surface pretension, and forms self-locking structure, then is finish-machined to be whole outer shroud again; In dress, encircle at 3 o'clock, between two conical surfaces of two conical surfaces of this integral body outer shroud and interior ring 3, coat lubricating grease.During use, earlier the utility model is contained on the axle sleeve 6, again with the correct position in the axle 7 insertion axle sleeves 6, order is tightened each high-strength bolt 4 gradually in accordance with regulations then, makes to produce between whole outer shroud and the interior ring 3 to endwisely slip, because the wedging structure of whole outer shroud and interior ring 3, make locking plate form radially positive pressure to axle sleeve 6, the moment of torsion of guaranteeing to produce between axle 7 and the axle sleeve 6 that stiction provided is fastened on the axle 7, to reach the purpose of transmitting torque axle sleeve 6 greater than transmitting torque.
