Background technique
Screw, screw rod or bolt are used for two or more component to tighten together.During these threaded link self-lockings, the frictional force that threaded support face produces prevents it from loosening.If when due to skidding, pretightening force is zero, can not mutually compress between screw thread, screw just may produce loosening when clashing into or shake.Therefore the anti-loosening of bolt is that bolt connects the major issue needing to solve always, and because of the vibrations of machinery, equipment, the time has been grown, and bolt will loosen voluntarily, even comes off; As a bolt looseness, come off, will machinery, device damage, even cause casualties accident, and economic loss is inestimable.
In prior art, the general stop pad that adopts prevents it from loosening, but the method cannot adapt to the bolt under complex working condition and under high pulling torque work, bolt now easily loosens, time serious, bolt also can drop out, therefore the normal use of equipment has been had a strong impact on, and some the anti-loosening assemblies not only complex structure occurred at present, and difficulty is installed.
Model utility content
The utility model is in order to solve the problems of the technologies described above, provide and a kind ofly install simple and the multi-position damper of bolt looseness can be prevented, avoid coming off of bolt, prevent the damage of equipment, ensure that personal security, thus use bolted component to remain on work in margin of safety.
The utility model is achieved through the following technical solutions:
A kind of multi-position damper, comprise idle wheel, damping block and be arranged on the damping arm of bolt periphery, damping arm is provided with at least two fastening arm with damping cavity, damping arm is fixed up through the damping cavity in damping arm by bolt, in the damping cavity of damping arm, intermeshing damping block and idle wheel are installed successively, idle wheel is provided with back-up ring.
Idle wheel installation cavity, damping block installation cavity and bolt through-hole is provided with in described fastening arm, damping arm is fixed up through the bolt through-hole in damping arm by bolt, in damping block installation cavity in damping arm, damping block is installed, in the idle wheel installation cavity in damping arm, the idle wheel engaged with damping block is installed.
Described idle wheel entirety is an outside is the cylindrical body of dentation, and cylindrical body inside center shape is hexagon in matching with bolt.
Described damping block outer wall is provided with the teeth be meshed with idle wheel.
Described fastening arm is also provided with the top wire hole passed for jackscrew, damping block outer wall is provided with the teeth be meshed with idle wheel, damping block is also provided with the aperture inserted for jackscrew, jackscrew is fixed on damping block through top wire hole and aperture.
Described fastening arm offers the draw-in groove snapped in for back-up ring, in draw-in groove, back-up ring is installed.
Compared with prior art, the utility model has following useful technique effect:
The multi-position damper that the utility model provides, by arranging the parts such as damping arm, damping block and idle wheel, adopts engagement or oblique wedge formula.When loading bolt, load manufactured damping arm simultaneously, after bolton, bolt will become to be integrated with damping arm, then idle wheel and damping block is loaded, reinstall back-up ring, being held out against by damping block with jackscrew makes it get involved damping arm side and idle wheel surface, formation carve and, stop bolt looseness, simultaneously, when bolt looseness, loosening force can pass to damping arm by parts such as idle wheels, damping arm will produce reaction force, thus constrain bolt looseness in damping arm, solve bolt looseness under various operating mode, working bolt state is met the requirements, and then make to remain in margin of safety with bolted component to work.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
See Fig. 1 to Figure 11, a kind of multi-position damper, comprise idle wheel 1, damping block 3 and be arranged on the damping arm 4 of bolt periphery, damping arm 4 is provided with at least two fastening arm with damping cavity, idle wheel installation cavity, damping block installation cavity and bolt through-hole is provided with in described fastening arm, damping arm is fixed up through the bolt through-hole in damping arm 4 by bolt, in damping block installation cavity in damping arm 4, damping block 3 is installed, the idle wheel 1 engaged with damping block 3 is installed in the idle wheel installation cavity in damping arm 4, idle wheel 1 is provided with back-up ring 2.Wherein, described idle wheel 1 entirety is an outside is the cylindrical body of dentation, and cylindrical body inside center shape is hexagon in matching with bolt.Described fastening arm offers the draw-in groove snapped in for back-up ring, in draw-in groove, back-up ring is installed.
Concrete, see Figure 11, described damping block 3 outer wall is provided with the teeth be meshed with idle wheel, and damping block 3 shape is crescent shape, and it directly engages with idle wheel and connects.
Or, see Fig. 6, described fastening arm is also provided with the top wire hole passed for jackscrew 5, damping block 3 outer wall is provided with the teeth be meshed with idle wheel, aperture damping block 3 being also provided with boss and inserting for jackscrew 5, jackscrew 5 is fixed on damping block 3 through top wire hole and aperture.
