Description
Technical field
The invention belongs to damper technique fields, and in particular to one kind has balance falling objects rate damper.
Background technique
During object fall, due to the effect of gravity, the speed of these objects can be getting faster.Object adds in gravity
Under the action of speed, can have very big speed and momentum in a short time, therefore, by the way that damper can be arranged to reduce object
The speed and momentum of body.In the manufacturing field of building, it will usually the conveying of material is carried out, if under the material with freely falling body
Drop, terminal velocity and momentum when reaching ground can be very huge, therefore, damper need to be arranged, to reduce speed, buffering punching
Amount.For existing damper during whereabouts is regulated the speed, smoothness is inadequate, it is necessary to given using suitable method it is perfect, so as to
Better damping is obtained, object fall is balanced, obtains more stable speed.
Summary of the invention
The purpose of the present invention is to provide one kind to have balance falling objects rate damper, falls convenient for being better balanced
The speed of object obtains more stable whereabouts effect, facilitates and falls behind under object eminence, steady to decline.
To achieve the goals above, technical scheme is as follows.
A kind of damper with balance falling objects speed, including outer housing are fixedly installed with damping structure in outer housing
Part and gear ring；Gear ring is arranged in damping member upper position；It is set in gear ring there are three planetary gear, is equipped with planetary gear in planetary gear
Axis, planet wheel spindle top are connected using planet wheel spindle fixed frame；Center sun gear is equipped among planetary gear；Center sun gear difference
It is engaged with planetary gear；Sun gear shaft is fixedly installed on the sun gear of center；Sun gear shaft passes through the installation of center sun gear and sets
It sets, center sun gear lower part is connected with using the fixed installation of sun gear shaft and gets rid of block mounting rack, is got rid of there are three the settings of block mounting rack
Uniformly on connection sun gear shaft side wall；Getting rid of is hollow cavity on the outside of block mounting rack, is caught in hollow cavity and is equipped with sliding and gets rid of block.
Further, planet wheel side is equipped with gear and engages with the gear on the inside of gear ring, the gear of center sun gear surrounding
It is intermeshed with planet wheel side equipped with gear.
Further, planet wheel spindle fixed frame is triangle frame, three of them angle point and the planetary gear being mounted on planetary gear
Axis is fixedly connected.
It further, is cavity inside damping member, inner cavity surface uses parabolic curve design, is linked by four convex-concave curves
It is formed, sliding is got rid of block and is fitted in damping member inner cavity surface.
Invention has the beneficial effects that: the sliding that the invention device can effectively utilize in damping member is got rid of block and is thrown away
Afterwards, the fricting movement in damping member inner cavity, so that planetary gear movement velocity during decline is controlled, so that under damper
During drop, the solar energy shaft of output speed obtains balancing speed effect on the sun gear of center, and falls with even pace, makes
With conveniently, product structure is simple, easy to install and use.

Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawings and examples, to better understand this hair
It is bright.
Embodiment
There is the damper of balance falling objects speed, including outer housing 1, outer housing 1 as shown in Figure 1, Figure 2 and described in Fig. 3
In be fixedly installed with damping member 2 and gear ring 4；Gear ring 4 is arranged in 2 upper position of damping member；Planet there are three being set in gear ring 4
5 are taken turns, planet wheel spindle 6 is equipped in planetary gear 5,6 top of planet wheel spindle is connected using planet wheel spindle fixed frame 8；Among planetary gear 5
Equipped with center sun gear 7；Center sun gear 7 is engaged with planetary gear 5 respectively；Sun rotation is fixedly installed on center sun gear 7
Axis 9；Sun gear shaft 9 passes through 7 installation settings of center sun gear, and sun gear 7 lower part in center is fixedly mounted using sun gear shaft 9
It is connected with and gets rid of block mounting rack 10, getting rid of the setting of block mounting rack 10, there are three on uniformly connection 9 side wall of sun gear shaft；Get rid of block mounting rack
10 outsides are hollow cavity, are caught in hollow cavity and are equipped with sliding and get rid of block 3.5 side of planetary gear is equipped with the tooth of 4 inside of gear and gear ring
Wheel engagement, the gear of 7 surrounding of center sun gear and 5 side of planetary gear are intermeshed equipped with gear；As shown in Figure 2.Planet wheel spindle
Fixed frame 8 is triangle frame, three of them angle point is fixedly connected with the planet wheel spindle 6 being mounted on planetary gear 5, as shown in Figure 2.Resistance
It is cavity inside Buddhist nun's component 2, inner cavity surface uses parabolic curve design, linked by four convex-concave curves and formed, as shown in figure 3, sliding
It is dynamic to get rid of block 3 and be fitted in 2 inner cavity surface of damping member.
It is cavity inside damping member 2 in the invention, inner cavity surface uses parabolic curve design, and sliding gets rid of block 3 and is fitted in resistance
In 2 inner cavity surface of Buddhist nun's component.As in the invention dropping process, sliding is got rid of block 3 and is moved in the cavity inside damping member 2, with
Damper fall, in getting rid of 10 rotation process of block mounting rack, sliding gets rid of block 3 as the cavity that gets rid of in block mounting rack 10 acts on,
It is fitted in 2 inner cavity surface of damping member.When block 3 is got rid of in sliding is in the convex surface of 2 inner cavity surface of damping member, sliding is got rid of block 3 and is squeezed
It is pressed onto the cavity inside damping member 2；When sliding gets rid of block 3 and be in the concave surface of 2 inner cavity surface of damping member, slide get rid of block 3 from
It is stretched out in cavity inside damping member 2, is fitted in sliding and gets rid of in 3 inner cavity surface of block.In this process, block mounting rack 10 is got rid of
Held stationary speed is rotated, center sun gear 7 is driven to drive, to drive three planetary gears 5 to drive, so that entire damper is protected
Steady fall is held, realizes equilibrium function.
As shown in figure 3, deriving formula centrifugal force F=sliding block quality * movement velocity * movement velocity/radius according to centrifugal force, i.e.,
F=mV2/ R, therefore, damping force and sliding block weight and speed direct ratio are inversely proportional with the radius of variation, as shown in figure 3, R2 is too
Sun wheel 9 outer surface of shaft and 2 inner surface farthest of damping member, R1 are 9 outer surface of sun gear shaft and 2 inner surface of damping member
Most nearby, sliding gets rid of block 3 with 2 inner surface frictionless contact of damping member, runs in the effect of centrifugation along curvilinear path.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
