Abstract

The invention discloses a self-reactive force coaxial washer. The self-reactive force coaxial washer has a washer body, wherein an outer contour of the washer body is a hexahedron, polyhedron or tooth-shaped surface structure; the cross section of an inner hole of the washer body is circular; the inner hole and a bolt are in clearance fit; and the upper surface of the washer body is a plane, and the lower surface is provided with an annular multi-convex or annular tooth-shaped structure. The self-reactive force coaxial washer has such advantages as increment of surface rotating friction force effect of a fastened object, reduction of nut rotating friction force, improvement of bolt pretightening force precision and prolonging of bolt life.

Description

The same shaft filler washer of a kind of self-reaction force

Technical field

The invention relates to technical field of fastening, and Specifically it is the same shaft filler washer of a kind of zero unbalance loading self-reaction force.

Background technique

Packing ring is a kind of conventional fastening piece, normal and bolt, nut screw connection use, now conventional packing ring has plain cushion, spring pad to be all standard piece, general packing ring is placed on below nut, when being for fastening nuts, reduce fastened thing skin friction, increase the mechanical strength of the thing that is locked, prevent from destroying fastened thing surface finishment, the effects such as anti-back.When reaching fastening pretightening force, spring pad becomes plain cushion does not have retaining effect, but causes bolt side direction unbalance loading excessive.Domesticly till now also do not solve bolt, nut, plain cushion, when fastening, produce the problem of bolt out of plumb and side direction unbalance loading in fastener.

Summary of the invention

The object of the invention is to provide and a kind ofly effectively prevents the same shaft filler washer of the self-reaction force of bolt out of plumb and side direction unbalance loading.Make in bolton process, this self-reaction force is with shaft filler washer and nut active force and reaction force coaxial rotating, eliminate common side direction unbalance loading, the bolt problem such as out of plumb in fastener caused due to rotary friction scrape along lateral force to occur, there is reduction rotating friction force, improve bolt pretightening precision, extend the advantages such as bolt life.

The object of the invention is achieved through the following technical solutions:

The same shaft filler washer of a kind of self-reaction force, there is washer body, the external frame of washer body is hexahedron, polyhedron or Profile of AT structure, the cross section of the endoporus of washer body is circular, described endoporus coordinates with bolt-clearance, the upper surface of washer body is plane, and lower surface is provided with annular many conveies or annular tooth-shape structure.

The same shaft filler washer of described self-reaction force, the annular tooth-shape structure of described lower surface is annular unidirectional tooth-shape structure or annular bidirectional tooth form structure.

The same shaft filler washer of described self-reaction force, the end periphery of the upper surface of described washer body is provided with downward-sloping slope type angle faces I.

The same shaft filler washer of described self-reaction force, the end periphery of the lower surface of described washer body is provided with acclivitous slope type angle faces II.

This brightthe beneficial effect created:

The advantages such as it is simple that the invention has structure, reliable lock, easy to use.In bolton process, self-reaction force is with shaft filler washer and nut active force and reaction force coaxial rotating, accomplish side direction unbalance loading be zero, eliminate common due to rotate, rub cause side direction unbalance loading, reduce nuts and washers junction plane frictional force, extend the life-span of bolt.When nut further rotates, bolt is by axial tension, now self-reaction force is provided with annular unidirectional tooth or annular multiple tooth-shape structure with shaft filler washer at packing ring lower surface, in use, self-reaction force relatively rotates with not had by the surface of tight thing with shaft filler washer, rotates the lower surface that only occurs in nut and with it between the upper surface of connecting part self-reaction force with shaft filler washer.

Embodiment

as Fig. 1-6the shown same shaft filler washer of a kind of self-reaction force, there is washer body 8, the external frame 1 of washer body 8 is hexahedron, polyhedron or Profile of AT structure, the cross section of the endoporus 3 of washer body is circular, described endoporus 3 and bolt 6 Spielpassung, packing ring endoporus can meet the condition of bolt direct-axis to single-way moving.The upper surface 4 of washer body is plane structure, and lower surface 2 is annular tooth-shape structure, and this annular tooth-shape structure can be annular unidirectional tooth-shape structure 5 as Fig. 5shown in or annular bidirectional tooth form structure as Fig. 6shown in. as Fig. 4the end periphery of the upper surface 4 of shown washer body 8 is provided with downward-sloping slope type angle faces I 4.1.The end periphery of the lower surface 2 of washer body is provided with acclivitous slope type angle faces II 2.1.The setting of this slope type angle faces solves in fastener cycle when snap close radial rotary half profile of tooth angle, under snap close locking state wrench can adopt below reversal of the natural order of things method install.Do not need to grasp wrench and people is hand steered, human users's Security significantly promotes.Preferably, as Fig. 7-9shown in this self-reaction force with shaft filler washer with the use of torque wrench and drive extender assembly 14 to have and overcoat, overcoat is fixedly connected with the housing of torque wrench is detachable, overcoat is set in this self-reaction force with on shaft filler washer, overcoat and self-reaction force are provided with latching device with shaft filler washer matching part, this latching device has annular snap close, this ring lock button bit 12 is between overcoat and self-reaction force are with shaft filler washer, the effect with shaft filler washer of the internal diameter of annular snap close 12 and self-reaction force is controlled by the lock catch shank 13 being placed in overcoat outside, thus this self-reaction force is fixed with shaft filler washer.

During use, first install lower nut 11 in the lower end of bolt 6, washer body 8 successively through the endoporus of fastened workpiece (lower flange 10 and upper flange plate 9), then is enclosed within bolt 6 by the upper end of bolt 6, then installs conventional hexagonal shape nut 7, state as Fig. 7shown in.

Rotating nut 7, as Fig. 7shown in, when nut 7 further rotates, due to nut 7 and packing ring 8 coaxial rotating, the active force therefore between nut 7 and packing ring 8 and reaction force payment are zero, and eliminate the side direction unbalance loading of bolt 6.While bolt 6 is by axial tension, the annular tooth-shape structure 5 of washer body 8 lower surface 2 and the upper surface of fastened workpiece surface and upper flange plate 9 define and do not rotate backing stop structure mutually.
