Specifically, performer 1 is fixed on its base 12, and casing 90 is fixed on its base 900.The end of blade 9 is provided with blades axes 91, and blade 9 is arranged in casing 90, and the sidewall that blades axes 91 is located at casing 90 rotationally can overturn in casing 90 to make blade 9, and the sidewall that blades axes 91 passes casing 90 inserts the core of follower gear 6 regularly.The output shaft 11 of performer 1 by comprising linkage assembly 2, first gear unit, the transmission rig of drive plate 678, second gear unit is connected with blades axes 91, overturn with driven vane 9.Disclose as aforementioned, in order to have all gear mechanism air door and global hinge type connection rod mechanism air door advantage concurrently, the transmission rig of the present embodiment comprises the gear mechanism of linkage assembly 2 and the formation of multiple gear unit, linkage assembly 2 is connected between the output shaft 11 of performer 1 and gear mechanism, and gear mechanism is connected with blades axes 91 and rotates with driven vane axle 91.
In order to simplify the structure of gear mechanism, the present embodiment comprises drive plate 678, and drive plate 678 ringwise and be sheathed on outside casing 90; Gear mechanism is connected with drive plate 678 to drive drive plate 678 to rotate, drive plate 678 by comprising multiple active tooth bar 7, the second gear unit of follower gear 6 is connected to drive each blades axes 91 to rotate respectively with multiple blades axes 91.In other embodiments, if do not use the instrumentality of the drive plate 678 that can drive multiple second gear unit and so on simultaneously, then need the first gear unit to drive multiple second gear unit respectively, obviously can increase the structure complexity of the present embodiment.
As shown in Figure 2, the linkage assembly 2 of the present embodiment comprises first connecting rod 21, second connecting rod 22, third connecting rod 23, the output shaft 11 of performer 1 is fixed in one end of first connecting rod 21, the other end of first connecting rod 21 is articulated with the first end of second connecting rod 22, second end of second connecting rod 22 is articulated with the first end of third connecting rod 23, and the second end of third connecting rod 23 is connected with the first gear unit of gear mechanism.
Again as shown in Figure 2, gear mechanism comprises the first gear unit, the second gear unit, and the first gear unit comprises driving toothed gear 5, driven tooth bar 8.Second gear unit comprises initiatively tooth bar 7, follower gear 6.Shown in composition graphs 1, second end of third connecting rod 23 is fixedly connected with one end of a main driving axle 4, the other end of main driving axle 4 is arranged on the inside of casing 90 by axle sleeve, it is inner that all the other passive blades axess 91 are along the circumferential direction evenly installed on casing 90, totally 14, blade, therefore, the casing 90 of casting is provided with 14 axle sleeves, 14 blades axess 91 are all through corresponding axle sleeve (running fit), and all blades axess 91 (comprising active and passive blades axes) can rotate in casing 90 with the axle sleeve of blade 9, blade 9 is fixed on main driving axle 4 with on passive blades axes, namely the region between casing 90 and each axle sleeve.Driving toothed gear 5 drives driven tooth bar 8 to rotate in the process of rotating, driven tooth bar 8 is fixedly connected with by screw with circular drive plate 678, driven tooth bar 8 drives drive plate 678 to rotate, drive plate 678 drives initiatively tooth bar 7 to rotate, initiatively driving passive gear 6 and passive blades axes 91 rotate by tooth bar 7, blades axes 91 driven vane 9 is rotated, and rest blade in like manner.
With regard to the mode of connection between each parts, more specifically, output shaft 11 with first connecting rod 21 for general flat key is connected; First connecting rod 21 and second connecting rod 22, second connecting rod 22, can relatively rotate for pin is connected with third connecting rod 23; Third connecting rod 23 and main driving axle 4, main driving axle 4 with driving toothed gear 5 for general flat key is connected; Driven tooth bar 8 and drive plate 678, initiatively tooth bar 7 with drive plate 678 for screw is fixedly connected with; Main driving axle 4 and blade 9, blades axes 91 with blade 9 for screw is fixedly connected with.
Preferably, follower gear 6 is half gear.
In addition, further preferably, each gear teeth of the gear mechanism of the present embodiment are provided with copper sheet, to reduce gap.
During application the present embodiment, performer 1 output torque, the member oscillates (or being referred to as to rotate) of linkage assembly 2, drive driving toothed gear 5 to rotate, driving toothed gear 5 drives driven tooth bar 8 to move, and driven tooth bar 8 is with nutating disk 678 to rotate again.Whereby, drive plate 678 drives remaining all active tooth bars 7 to move, and initiatively tooth bar 7 drives follower gear 6 to rotate, follower gear 6 is installed on the blades axes 91 of each blade 9, therefore, when follower gear 6 rotates, it driven vane 9 can turn to different angles, thus realizes air door adjustment.
When applying the present embodiment and transforming prior art, first by the mode of pad copper sheet, the gap between each wheel and rack can be adjusted, eliminates this section transmission error.
Then change the geartransmission that performer 1 output shaft 11 connects into link transmission, eliminate the gear drive error between performer 1 and tooth bar.If former performer moment too small (such as 300N.M), blade 9 possibility often jam, can consider performer moment being increased to 600N.M.The transmission rig of output is linkage assembly, and have structure formation simple, reliable working performance, debugs conveniently feature.If the installation form of performer and base dimensions and former performer are not altogether, such as former performer adopts at right angle setting mode, and selected performer is horizontal mounting means (normally injecting gear oil), so, the necessary half-twist of air door, makes base to casing 90 again simultaneously.
Put into practice from test and analyze, the utility model can obtain following technique effect:
One, simple and practical, integrate traditional all gear mechanism air door and global hinge type connection rod mechanism air door advantage, low cost of manufacture.Comparatively ball-and-socket hinge style linkage assembly air door structure is simple, cost is low, performer output adopts linkage assembly, when avoiding adopting merely gear mechanism, due to the zero offset that the driving errors such as gear backlash cause, drive plate drives damper blade can reduce the cost of whole device, takes into account the advantage of the wheeled air door of full-depth tooth and global hinge type connection rod mechanism air door.
Two, less demanding to producing apparatus, cost is low.The spare part that the utility model can utilize the spare parts such as idle performer, other equipment repairs are displaced, under the condition not changing air door, complete air door transformation, and parameters all reaches expection requirement, saves air door outsourcing expense.
Three, simple to operate, maintenance cost is low.Owing to adopting general electric performer, and use linkage transmission, equipment failure rate is extremely low, and complete machine oscillation is little, and structural rigidity is good, and lubrication is convenient, and part replacement is easy, and mechanism's output torque is adjustable, ensures the reliable action of damper blade.
Four, reliable operation, has good economic benefit.Realize combustion air amount adjustable after, hot blast stove burning technological quality is greatly improved, and saves blast furnace gas consumption, reduces blower fan power consumption, year create beneficial result can reach for 500,000/year.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
