Embodiment
Below we come low-speed diesel engine tachogenerator support of the present utility model done further with specific embodiment in conjunction with the accompanying drawings and elaborate, but can not limit protection domain of the present utility model with this.
Sensor stand of the present utility model is taken all factors into consideration the construction profile of three kinds of sensors, factors such as the feasibility of on-the-spot actual installation and convenience respectively are divided into two parts with three kinds of supports and make a heavy pound flange physical dimension on the fixed support of three kinds of supports and the frame, position dimension obtain unified.
The structure of the utility model low-speed diesel engine tachogenerator support comprises the adjusting support that is installed on the fixed support on the heavy pound of the frame flange and is installed in fixed support one end, described fixed support has a flange with the contacted end of adjusting support, the center of this flange is provided with a screw, described adjusting support comprises web joint and fixture, the top of described web joint is provided with a Long Circle hole, a screw passes described screw and with the Long Circle hole web joint is connected with fixed support, and described fixture is fixed in the bottom of web joint.
At the tachogenerator of different models, adopt following specific design:
When such scheme specifically is applied to I type tachogenerator support, described fixture is a rectangular slab, four jiaos at rectangular slab are provided with four fixed orifices, the L-shaped vertical fixing in the bottom of rectangular slab and described web joint, vertical fixing floor between the angle of web joint and rectangular slab.Shown in two width of cloth figure of Fig. 4, Fig. 4 a is the front elevation after I type tachogenerator support of the present utility model improves, and Fig. 4 b is the vertical view after I type tachogenerator support of the present utility model improves.
When such scheme specifically was applied to II type tachogenerator support, described fixture was two square plates, and this square plate is parallel to each other and is welded in the both sides of described web joint.Shown in two width of cloth figure of Fig. 5, Fig. 5 a faces structural drawing after II type tachogenerator support of the present utility model improves, and Fig. 5 b is that II type tachogenerator support of the present utility model improves back plan structure figure.
When such scheme specifically is applied to III type tachogenerator support, described fixture is two and has the upwards flat board of flange, on described flange, be provided with screw, the bottom of described web joint is provided with the screw hole corresponding with screw on the flange, by set bolt fixture and web joint is fixed.Shown in two width of cloth figure of Fig. 6, Fig. 6 a faces structural drawing after III type tachogenerator support of the present utility model improves, and Fig. 6 b is that III type tachogenerator support of the present utility model improves back plan structure figure.
Improve the state and the effect of front and back by tachogenerator among Fig. 7, Fig. 8, Fig. 9 embodiment 1, Fig. 7 is the application state figure among the low-speed diesel engine tachogenerator support embodiment 1 of the present utility model, Fig. 8 be B among Fig. 7 to view, Fig. 9 is the enlarged drawing at M place among Fig. 7.Can be well understood to improved concrete mode more by accompanying drawing.
Certain S60MCC diesel engine uses I type tachogenerator support.Before it was revised, heavy pound position dimension a, a b, support processing dimension c, flywheel physical dimension d be because the existence of foozle, influenced gap f between flywheel tooth top and the sensor (about 1.5～2mm), make gap f often overproof, as shown in figure 10; And the heavy pound of frame flange angle e has influenced the depth of parallelism requirement between flywheel tooth top and the sensor again because of the existence of foozle.Heavy pound needs repeatedly location welding, and the accuracy of heavy pound position can't guarantee that protected working is difficult to handle properly during welding during the location.
After the design improvement, support is divided into fixed support and regulates support two parts.Kidney slot between two sections supports is regulated and angular adjustment is easy to guarantee gap f and depth of parallelism requirement, heavy pound position dimension a, b have been compensated, support processing dimension c, the influence of the foozle of flywheel physical dimension d and heavy pound angle e, make the position dimension and the physical dimension of the heavy pound of frame flange obtain restriction definite and that broken away from the depth of parallelism (or angle f), avoided repeatedly reorientating freezing, reduced the difficulty of on-the-spot actual installation, improved the accuracy of on-the-spot actual installation, save labour cost, significantly promoted efficiency of assembling.
In addition, after the sensor stand of three kinds of models improved, fixed support obtained unified, regulated support and then did structural conversion according to the version of three kinds of model tachogenerators and number of sensors and concrete installation requirement different.For example, I type support is used in the Norcontrol tachogenerator, and it regulates support is a L type support with the threaded hole of four M18*1, and these four threaded holes then are used to install four tachogenerators of Norcontrol; II type support is used in the Nabtesco tachogenerator, and it regulates support is a H type support with eight bolt holes, and these eight bolt holes divide two groups of two tachogenerator boxes that are used to install Nabtesco respectively; And III type support is used in the Lyngso tachogenerator, its regulate support be one with the bolt hole of six Φ 20 and the support of a mounting hole, they are respectively applied for six tachogenerators and top dead center position sensor that Lyngso is installed.Make like this fixed support only with type S46MCC, S50MCC, S60MC, S60MCC, S70MC, S80MCC about and and the model Norcontrol of tachogenerator, Nabtesco, Lyngso is irrelevant, and it is only relevant with the model of tachogenerator and irrelevant with type to regulate support.
Because rate signal is most important to diesel engine stable operation, capable degree must be guaranteed so the assemblage gap of tachogenerator will be demanded for peace.Take all factors into consideration the construction profile of three kinds of sensors, factors such as the feasibility of on-the-spot actual installation and convenience respectively are divided into two parts with three kinds of supports and make a heavy pound flange physical dimension on the fixed support of three kinds of supports and the frame, position dimension obtain unified; Adjusting surplus Δ between support two parts has been eliminated flywheel physical dimension D again simultaneously, bent axle processing dimension S, support processing dimension P, frame processing dimension H (heavy pound welds before frame finishing), heavy pound position dimension A, B and angle E, tachogenerator contoured cradle size Q is to the gap F of sensor and the influence of depth of parallelism G requirement, that is:
F＝f(D)+f(S)+f(P)+f(H)+f(A)+f(B)+f(Q)-Δ
Then can draw:
Δ F=Δ f (D)+Δ f (S)+Δ f (P)+Δ f (H)+Δ f (A)+Δ f (B)+Δ f (Q)-Δ, and the Δ span is-30mm～+ 30mm, need only so:
|Δf(D)+Δf(S)+Δf(P)+Δf(H)+Δf(A)+Δf(B)+Δf(Q)-ΔF|＜30mm，
We just can eliminate the influence of above-mentioned size foozle to gap F by the relative displacement of regulating between New-support two parts (regulating the surplus Δ); And while G=f (E) regulates support by rotation and guarantees depth of parallelism G, and the feasible gap herein and the depth of parallelism more are easy to get.Reasonably the supporting structure design greatly reduces the difficulty of on-the-spot actual installation, and labour cost has been saved in the accuracy that has improved on-the-spot actual installation, has significantly promoted efficiency of assembling.
After this design improvement, after too much the platform diesel engine is installed and used, gap when tachogenerator the is installed face degree of will demanding for peace requires to be easy to guarantee, have install simple, advantage such as when having saved the millwright, and be successfully applied to S46MCC, S50MCC, S60MC, S60MCC, S70MC is on the multiple marine low speed diesel engine such as S80MCC.
