Abstract
The utility model discloses a speed self-balancing device comprising a machine shell, a shaft and a disc assembly. The disc assembly is composed of a disc, vanes, springs, blocks and connection ropes. The shaft is installed on the machine shell. The disc assembly and the shaft are coaxially installed on the machine shell, the vanes are installed in chutes of the disc, one end of each spring is installed on the disc, the other end of each spring is installed at the bottom of the corresponding vane, and the blocks are connected with the bottoms of the vanes through the connection ropes. The speed self-balancing device can effectively solve the problem of speed fluctuation, and is simple in structure, low in cost and high in practicability.
Description
Technical field
The utility model relates to a kind of speed self balancing device, belongs to velocity balance device research field.
Background technique
At present, some equipments need speed to change as requested, some time require again speed to keep certain.Velocity variations is divided into again two kinds of modes: first step change, mainly take casing speed changer as main; It two is stepless speed variators, and representative is hydraulic transformer.
When needs equipment speed keeps certain value, only need step change transmission according to a kind of fixed drive ratio work, at this moment just can simply realize operation or the work of single rotating speed.But while utilizing the work of the certain speed changer of this register ratio, vibration is large, it is excessive etc. to impact.In addition, hydraulic transmission requires highly to device, and demand precision is high, will cause like this cost significantly to rise.
Above-mentioned said velocity balance mode has following deficiency and shortcoming: impact excessively, vibrate greatlyr, cost is higher, and therefore a kind of device of constant airspeed that can keep seems extremely necessary.
Summary of the invention
In order to overcome the deficiencies in the prior art and defect, the purpose of this utility model is to provide a kind of speed self balancing device.It not only can meet above-mentioned requirement, and simple in structure, expense is cheap, application is strong.
It is a kind of speed self balancing device that the utility model solves the technological scheme that its technical problem adopts, comprise casing (1), axle (2), disc assembly (3), it is upper that described axle (2) is installed to casing (1), and described disc assembly (3) and axle (2) are coaxially installed on casing (1);
Disc assembly (3) is comprised of disk (4), blade (5), spring (6), thing piece (7), bridle line (8), it is characterized in that: described blade (5) is arranged in the skewed slot of disk (4), described spring (6) one end is arranged on disk (4), one end is arranged on the bottom of blade (5), and described thing piece (7) is connected with blade (5) bottom by bridle line (8).
The working principle of a kind of speed self balancing device of the utility model is:
First, this self balancing device is fixed to some places, now, blade is the ragged edge in disk under the force action of spring thrust and thing piece power; Meanwhile, due to the inextensibility of bridle line, thing piece is pulled to the position nearest apart from circle disk center under the effect of bridle line.Then, allow breeze animated blade that disc assembly is rotated around axle, now, under the effect of circumference centrifugal force, because the mass force of thing piece is greater than mass force and the pre-thrust sum of spring of blade, therefore, thing piece starts away from disc centre along track, now, under the effect that blade is made a concerted effort at thing piece mass force and spring force, start to move toward disc centre, wind speed is larger, the centrifugal force of thing piece is also larger, the area that makes like this blade be exposed at disk outside dwindles along with the increase of disk speed, blade area is dwindled the suffered wind-force of blade is reduced, now the rotating speed of blade declines thereupon, so that it maintains a substantially invariable numerical value.When wind speed reduces, because thing piece centrifugal force reduces, therefore, at spring thrust and thing piece centrifugal action lower blade along disk diameter to moving outward, now, the exposed enlarged areas in disk outside of blade, also makes the suffered wind-force of blade increase simultaneously, the rotating speed of disk can be adjusted up at once thereupon, to maintain a metastable numerical value.
The beneficial effects of the utility model are that this speed self balancing device can be adjusted rotating speed automatically according to the size of wind-force, makes it remain on a metastable rotating speed, to guarantee that the convenient of other devices used.
