Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, it is double to provide a kind of hydraulic test bench
Transmission shaft synchronous belt coupling device solves the problems, such as that existing coupled system is affected to test bed testing value accuracy.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of double transmissions of hydraulic test bench
Axis synchronous belt coupling device, including multiple synchronous pulleys for being separately mounted on more transmission shafts；The multiple synchronous pulley it
Between by synchronous belt be connected；For two adjacent transmission shafts, at least a transmission shaft and for adjusting two transmission shafts
Two synchronous pulleys between centre-to-centre spacing regulating mechanism connection.
The every transmission shaft is by a driving mechanism（Power source）It drives, in the utility model, driving mechanism can be
Motor（Containing variable-frequency motor）, various internal combustion engines or various hydraulic motors.Power source, which can directly drive transmission shaft, can also lead to
Cross gearbox driving load.
Shaft coupling, torque rotational speed meters and other sensors can also be installed on the every transmission shaft.
Each shaft coupling couples with a set of load, and load can be various hydraulic pumps, generator（It generates electricity containing AC and DC
Machine）, hoist engine, hydraulic dynamometer or electric dynamometer machine.
By a bearing block support, each bearing block is respectively installed on a pedestal the every transmission shaft.
The regulating mechanism includes at least one driven in translation machine, and the output shaft of each driven in translation machine correspond to
One pedestal/bearing block connection.
Guiding mechanism is set between adjacent two transmission shafts.When ensureing mobile, the depth of parallelism of two transmission shafts.
It is provided with position block between two bearing block/pedestals of adjacent two transmission shafts.It is accurate to ensure that centre-to-centre spacing is adjusted.
Position block can be dead（It is fixed）Block can also be the parts just to play the role of positioning after other movements in place.
Synchronous belt hanger is fixed on bearing block, when centre-to-centre spacing reduces, synchronous belt unclamps, and when coupling releases, can will unclamp
Synchronous belt removed from belt wheel, be hung on synchronous belt hanger.There is the lock for preventing synchronous belt from skidding off on synchronous belt hanger, prevents
Only synchronous belt falls the transmission shaft with rotation.Synchronous belt hanger is mounted on by screw on bearing block, and lock is existed by screw lock
On hanger.
Compared with prior art, it is had the beneficial effect that possessed by the utility model：The utility model be suitable for have two with
On（Containing two）The hydraulic test bench of transmission shaft transmits torque up to 2000N.m, and rotating speed is up to 2000rpm, and whole device is transported
For the quality of moving part within 100Kg, the influence to test bed testing value is small, and maintains easily.
Description of the drawings
Fig. 1 is the utility model embodiment structural schematic diagram.
Specific implementation mode
As shown in Figure 1, the utility model embodiment synchronous belt coupling device is driven for any two in hydraulic test bench
Power coupling between axis, the mainly synchronous pulley 10 by being separately mounted on two transmission shafts（2）, synchronous belt 9, bearing pass
The groups such as the bearing block 11 of moving axis, the pedestal 7 of installation transmission shaft and bearing block, center transmission shaft distance regulating mechanism, synchronous belt hanger
At.
Synchronous belt coupling device can facilitate the switching for realizing that synchronous belt input is engaged and is disengaged from, without dismounting bearing
Seat and transmission shaft, are not required to remove synchronous pulley.The centre-to-centre spacing that two transmission shafts need to be only adjusted when switching can be realized.When centre-to-centre spacing increases
When big, synchronous belt tensioning, band tooth input engagement plays the dynamic coupling effect of two between centers.At this point, can will have on any transmission shaft
Power more than needed is coupled to by toothed belt transmission on another transmission shaft, conversely, on a certain axis when being short of power, it is another
Power on root transmission shaft can also be coupled by synchronous belt to be supplemented.When the centre-to-centre spacing of two transmission between centers reduces, synchronous belt
It is unclamped with belt wheel, the power coupling of twin shaft releases, two transmission shaft independent operations.Shaft coupling can also be installed on every transmission shaft
12, torque rotational speed meters nT and other sensors.
In the utility model, bearing block is arranged in synchronous pulley both sides, is used for supporting drive shaft.
Two center transmission shafts away from adjusting realized by the regulating mechanism of the present apparatus.The center distance regulating mechanism can be used
The mode for directly driving pedestal can also be used in driving bearing block mode.The power of driving can be man-operated mechanism, can also be by liquid
Cylinder pressure, cylinder or motor drive, and driven in translation machine 6 is used in the utility model.When to ensure mobile, two transmission shafts it is parallel
Degree, is provided with guide part（That is two sets of guiding mechanisms are arranged in the utility model, are respectively arranged at transmission shaft two for guiding mechanism 1
End）, guide part can be the linear guide or V-shaped groove.To ensure that centre-to-centre spacing is adjusted accurate, between the pedestal of two transmission shafts
（Or between bearing block）Provided with position block, which can be fixed stop, can also be after other movements in place just
The parts to play the role of positioning, in the utility model, on the inside of two bearing blocks of one of transmission shaft（I.e. close to another transmission
The side of bearing housing）It is respectively provided with the first position block 2, the second position block is also provided between the adjacent bearing block of two of which
