Abstract
Increase slow formula orientation damper, including gear, impeller, cover plate, base and sealing ring, the impeller includes some blades and central shaft, and impeller is positioned in the cavity of base upward by central shaft, is cased with sealing ring, cover plate and gear on the central shaft successively from top to bottom；Damping oil is also filled with the cavity.The utility model employs the aufbauprinciple of half arc impeller, the blade of half meniscus shaped is wide outside and narrow inside, outer ring orphan's line length to push all damping oils to outer ring when rotating forward, damping area is set to diffuse into maximization, so as to just reach the purpose for increasing resistance, the lonely line of inner ring is short to mitigate resistance, by damping oil to contract during reversing, so as to reach the purpose for the more turning the more light, performance is superior with acting on, low cost, it is widely used, available for self-locking lock body, various high-grade bins and renovate, ejection has resistance when being used as power using spring, but the elastic force of spring is not in itself subtracted, mitigate damping force during retraction so that easily returning.
Description
Technical field
Damper device technical field is the utility model is related to, more particularly to increases slow formula orientation damper.
Background technology
Make the various frictions and other inhibitions that free vibration decays, we term it damping.And it is placed in structure system
" special " component on system can provide the resistance of motion, and the device of depletion kinergety, we are referred to as damper, and it extensively should
For in all trades and professions.But existing damper structure is complicated, installation trouble, aufbauprinciple science not enough, can not rise
To good performance and effect, purposes scope is small, and cost is also high.
Utility model content
The utility model will solve problem of the prior art, there is provided increase slow formula orientation damper, structure is simple with installation, property
Can be with acting on superior, low cost.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
Increase slow formula orientation damper, including gear, impeller, cover plate, base and sealing ring, the impeller include some blades
It is cased with successively from top to bottom and central shaft, impeller are positioned in the cavity of base upward by central shaft, on the central shaft close
Seal, cover plate and gear；Damping oil is also filled with the cavity.Cover plate and sealing ring seal the cavity of base, avoid hindering
The spilling of Buddhist nun's oil.
Preferably, the central shaft bottom is cylinder, and top is oval post, is offered on cover plate in matching with cylinder
Heart circular hole, the center waist round hole to match with oval post is offered on gear.Sealing ring and cover plate set and central shaft after assembling
The oval shell of column part of cylindrical section part, geared sleeve and central shaft.
Preferably, the seal groove for accommodating sealing ring is offered on the impeller.Play better seal effect, and energy
Avoid the deformation for causing sealing ring because of wheel rotation.
Preferably, counterbore is provided with the base openings, is fixed in cover plate press-in counterbore.Fixed form is to pass through ultrasonic wave
Welder, cover plate is set to weld together with base counterbore, Stability Analysis of Structures, good sealing effect.
Preferably, the base both sides are provided with lug, the fixed installation for damper.
Preferably, the blade is in shape wide outside and narrow inside, and its curve is in half arc or half meniscus shaped.
Preferably, annular boss is provided with around the center hole of the cover plate upper surface so that assembling backgear and cover plate
Upper surface has certain gap, gear and the friction of cover plate upper surface when reducing damper work.
The beneficial effects of the utility model are：The aufbauprinciple of half arc impeller is employed, outside the blade of half meniscus shaped
Narrow in width, outer ring orphan's line length to push all damping oils to outer ring when rotating forward, and damping area is diffused into maximization, so as to just reach
To the purpose for increasing resistance, the lonely line of inner ring is short to mitigate resistance, by damping oil to contract during reversing, so as to reach the more turn the more light it
Purpose, structure is simple with installation, and performance is widely used with acting on superior, low cost, various available for self-locking lock body
High-grade bin and renovate, ejection has resistance when being used as power using spring, but does not subtract the elastic force of spring in itself, subtracts during retraction
Light damping force is so that easily return.
