Description
Technical field
Threst stand equipment is the utility model is related to, particularly a kind of threst stand transition support dress
Put.
Background technology
Moment of torsion is an important parameter of engine performance, refers to the mean force exported during engine operating from crankshaft end
Square, it is commonly called as " turning strength " for engine.Moment of torsion is bigger, and " strength " of engine output is bigger, and the change of speed of crankshaft is also faster, vapour
The climbing capacity of car, starting speed and acceleration are also better.Moment of torsion is different with the change of engine speed, and rotating speed is too high or too
Low, moment of torsion is not maximum, only just has peak torque in some rotating speed or in some rotating speed section, and this section is exactly to mark
Go out the rotating speed provided during peak torque or rotating speed section.Peak torque is generally present in engine, the scope of the slow-speed of revolution, with
The raising of rotating speed, moment of torsion can decline on the contrary
In general, the highest index of moment of torsion engine speed compare it is relatively low in the case of can reach, just explanation
The engine technology of this car is preferable, and strength might as well.For family-sized car, moment of torsion is bigger, and acceleration is better；For cross-country
Car, moment of torsion is bigger, and its climbable gradient is bigger；For lorry, the weight that moment of torsion more cart is drawn is bigger.The moment of torsion of car more it is big just
It is better, it is also that so, in the case of discharge capacity identical, moment of torsion is bigger, and explanation engine is better when traveling.Moment of torsion is to comment
One of major parameter of a car performance of valency.Evaluating a car has a significant data, is exactly the car at 0-100 kilometers/hour
Acceleration time.And this acceleration time is dependent on the moment of torsion of automobile engine.
But when the moment of torsion of engine is measured in engine test stand, often due to the torsion shake that engine passes over is led
Cause the torque sensor measured value on dynamometer machine unstable, while turn round shake and also result in the appearance of dynamometer machine some mechanical breakdowns, pin
To this case, it is necessary to develop a kind of threst stand transition support meanss.
The content of the invention
The purpose of this utility model is to eliminate the torsion shake that engine passes over, prevent dynamometer machine measurement is unstable from showing
As；Dynamometer machine is protected simultaneously, reduces the fault rate of dynamometer machine in laboratory.
The technical solution adopted in the utility model is：A kind of threst stand transition support meanss, including bearing block,
Intermediate supports and shaft coupling, intermediate supports are erected on bearing block；It is characterized in that：
The bearing block includes covering on bearing block lower cover and bearing block, on bearing block lid be fastened on bearing block lower cover just on
Side；
The intermediate supports include sleeve pipe on the same axis, adpting flange, end cap, ball bearing, copper packing, axle and
Axle sleeve；The ball bearing is used to reduce frictional resistance, the adpting flange and transmission axis connection；
The shaft coupling includes clutch, yielding rubber pad and torque flange composition, the shaft coupling and intermediate supports position
In on same axis and there is fail safe function, caused vibrations and punching in running effectively can be damped and reduced
Hit.
Further, the adpting flange and transmission axis connection, while be fixedly linked with one end of axle；Sleeve pipe both ends and end
Lid is connected by screw, and all drives its rotation by axle；The ball bearing for support shaft is connected on the inside of end cap simultaneously；
The other end of axle is connected to axle sleeve, and the other end of axle sleeve is connected with being connected shaft coupling.
Further, the torque flange is connected with axle sleeve；Clutch is connected with dynamometer machine adpting flange；In moment of torsion
Yielding rubber pad is provided between flange and clutch.
The beneficial effects of the utility model and feature are：(1) the torsion shake that engine passes over is eliminated, prevents dynamometer machine from surveying
Measure unstable phenomenon；(2) while to dynamometer machine protect, reduce the fault rate of dynamometer machine in laboratory.
