Abstract
The utility model belongs to a device which is structurally connected with the electric motor, in particular to a transmission connecting part between the diesel engine and the electric motor in the monoblock and simplex water cooling diesel fuel electric generating set. The utility model is a monoblock and simplex water cooling diesel fuel electric generating set, which comprises a simplexwater cooling diesel engine and an electric motor. The structural main point is that: a gear transmission box is connected between the simplex water cooling diesel engine and the electric motor, while the simplex water cooling diesel engine output axes is connected with a driving gear through an elastic shaft joint; the input shaft of the electric motor is connected with a driven gear through the other elastic shaft joint, while the driving gear is mutually joggled with the driven gear. The utility model has the advantages of changing the former belt transmission into gear transmission, realizing a fixed transmission ratio between the diesel engine and the electric motor, having high transmission efficiency, being conductive to adjusting the engine frequency and the steady state of the voltage.
Description
Technical field
The utility model belongs to the device that is connected with motor on the structure, relates in particular to the transmission joint part between the diesel engine and generator in the direct connection single-cylinder water-cooling diesel generating set.
Background technique
Replace hand labour in vogue with machinery now, consumer increases, thereby power generating equipment is also more and more, because single-cylinder water cooled diesel engine has powerful, cheap, advantages such as operation and maintenance is convenient, be subjected to liking of the numerous consumer groups deeply, its rotating speed is generally between 2000rpm-2600rpm, be two kinds of 1500rpm and 3000rpm and the rotating speed of generator is commonly used, the two can not directly connect, needs to realize by speed change gear, and all be to adopt strap speed varying as shown in Figure 1 to realize at present.This gear is when generator impact or anticlimax load, be easy to generate skidding, influence the load proper functioning, require belt will have certain pretightening force to be stretched on the belt pulley, could reduce the probability that skids between band and the belt pulley, this makes the generator input shaft end bear big radial force tension force, and to the requirement of strength height of axle and end cap, and the fixing of belt elasticity sliding motion velocity ratio influences very big to generator frequency, the adjustment of voltage stable state.Belt transmission has following several apparent in view shortcomings: 1) overall sizes of driving mechanism is bigger; 2) need tension device; 3) because the elasticity sliding motion of band can not guarantee changeless velocity ratio; 4) Dai life-span is shorter; 5) transmission efficiency is lower.
Summary of the invention
The utility model overcomes deficiency of the prior art, and a kind of compact structure is provided, and has fixed drive ratio, the direct connection single-cylinder water-cooling diesel generating set that transmission efficiency is high.
The technological scheme that the utility model adopted is a kind of direct connection single-cylinder water-cooling diesel generating set, comprise single-cylinder water cooled diesel engine, generator, its structure outline is to be connected with speed-changing gear box between single-cylinder water cooled diesel engine and generator, the output shaft of single-cylinder water cooled diesel engine links to each other with driving gear by elastic coupling flexible coupling, the generator input shaft links to each other with driven gear by another elastic coupling flexible coupling, and driving gear is meshed with driven gear.
The purpose of this utility model can also be realized better by following improvement.
The shared same end cap of speed-changing gear box and generator has reduced an end cap and an elastic coupling flexible coupling, has reduced manufacture cost.
Advantage of the present utility model is to change original band transmission into gear transmission, overcome the various shortcoming of band transmission, make fixing velocity ratio has been arranged between diesel engine and the generator, transmission efficiency is higher, help generator frequency, the adjustment of voltage stable state, do not need tension device, the working environment of generator input shaft end is improved, and has reduced rate of fault.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail
As shown in Figure 2, embodiment 1, a kind of direct connection single-cylinder water-cooling diesel generator, comprise single-cylinder water cooled diesel engine 1, generator 2, between single-cylinder water cooled diesel engine 1 and generator 2, be connected with speed-changing gear box 3, the output shaft 11 of single-cylinder water cooled diesel engine 1 links to each other with driving gear 31 by elastic coupling flexible coupling 4, elastic coupling flexible coupling 4 is except playing the assembly error that also can adjust the buffer function between output shaft 11 and the driving gear 31, generator 2 input shafts 21 link to each other with driven gear 32 by another elastic coupling flexible coupling 4, and driving gear 31 is meshed with driven gear 32.
As shown in Figure 3, embodiment 2, speed-changing gear box 3 and generator 2 shared same end caps 22, and generator 2 input shafts 21 directly link to each other with driven gear 32, can be less with elastic coupling flexible couplings, it is identical with last example that all the other do not state part.
