Abstract
A device which can make the dynamic-performance test for the synchronous belt is on the basis of the principle of the prior V belt mechanical-sealing tester, which changes the testing V belt into the synchronous belt and makes a active shaft and a passive shaft strictly operating according to the meshing transmission (without the sliding movement) of the synchronous belt; the transmission ratio between the two shafts can be randomly chosen; as long as the transmission ratio of the assistant V belt matching the synchronous belt, the various dynamic-performance tests and examinations of the synchronous belt can be done.
Description
The utility model relates to a kind of device that can carry out various dynamic property tests to synchronous band transmission.
At present, be with transmission test device mostly to be two kinds of structural shapes synchronously, a kind of is the open type test unit, and a kind of is electric blocking test device.The open type test unit is that the load of test power by synchronous band transmission directly consumed.Its load mode has current vortex loading, the loading of electromagnetism powder and hydraulic loaded etc., and these shortcomings that load patterns are to cost an arm and a leg, and energy dissipation is big.Electricity blocking test device is to utilize synchronously that band drives generator for electricity generation, makes the electricity that sends input to electrical network and returns and be used for motor work.But electricity blocking test device saves energy 60～65%, this device for mechanical is simple in structure but the power recovery system is complicated, costs an arm and a leg, and stops long-pending big.
The purpose of this utility model is to utilize the mechanical close principle that synchronous band transmission is tested and detected.Utilize the synchronous girdle tests device of this principle design to have good energy-conserving effect (can reach 75～85%), compact conformation, volume are little, cheap, running steadily, advantage such as dependable performance, and can test and detect various dynamic properties such as the load-bearing capacity of synchronous band, fatigue lifetime, reinforcement fatigue lifetives.
The purpose of this utility model is achieved in that
According to known mechanical close testing machine principle, in Fig. 1, the A end is equipped with tested synchronous band for the test limit, and the B end connects with the V band for auxiliary limit.The I axle is a main drive shaft, and the II axle is a driven axle, and the subband that torque speed sensor N, adjustable diameter are installed on main drive shaft I loads belt wheel D
1Be with driving pulley T synchronously with test
1On driven axle II, be equipped with and load auxiliary belt wheel D
2, the synchronous band follower T of initial tension bringing device K, universal shaft W and test
2Above system has formed the mechanical close system of synchronous girdle tests machine.
Main motor M drives main drive shaft I rotation by polywedge bet F in Fig. 1, at D
2/ D
1And T
1/ T
2Under the situation that ratio of gear equates, the rotation of I axle and II axle is strict with above-mentioned ratio of gear work, and this moment, closed system was sentenced unloaded lotus running status.Work as D
1D during minimizing
2/ D
1Increase, this moment, system just produced confining force stream.Because band transmission synchronously is an engaged transmission, so the rotating speed of I axle and II axle is strict with T
2/ T
1Ratio of gear work.Because D
1Minimizing D
2Rotating speed should be less than T
2Rotating speed, again because of D
2And T
2For coaxial, so T
2Just become driving wheel in the II axle, the auxiliary V band of this moment is just at D
2With D
1Between produce to slide (in the transmission of V band, being called sliding ratio), the sliding ratio of V band transmission has just produced moment of torsion to total system, this moment of torsion is exported to secondary instrument or computing machine by the torque speed sensor N of I axle with signal, after carrying out data processing, just can read corresponding torque, rotating speed and performance number.
The utility model is to implement like this:
I axle and II axle are vertical layouts up and down in Fig. 2, also can be horizontally disposed, and the I axle is made up of three parts, that is: loaded ribbon wheel shaft [7], torque speed sensor [23] and active experiment belt shaft [21].The loading belt wheel [6] of adjustable diameter is installed, bearing seat [5] and motor-driven follower [4] on loaded ribbon wheel shaft [7].Active experiment belt wheel [20] is installed, bearing seat [5] on active experiment belt shaft [21].Connect with elastic coupling [22] between this three part.The II axle also is made up of three parts, promptly passive loaded ribbon wheel shaft [13], universal shaft [15] and passive test tape wheel shaft [16].Passive loading belt wheel [9] bearing seat [14] is installed on passive loaded ribbon wheel shaft [13].Passive test belt wheel [18] and bearing seat [14] are installed on passive test tape wheel shaft [16].Flange by universal shaft [15] between three parts of II axle connects, the clearly demarcated connection with line slideway [17] also of two bearing seat [14] can slide on guide rail, fix two initial tension bringing devices respectively at the left and right sides of II axle, be weight [10], pulley [11] and the wire rope [12] among Fig. 2, right side weight [10] can be changed its weight according to the test requirement of band [19] synchronously.Universal shaft in the II axle [15] is that warranty test is with the deviation that causes because of central moment is different between [8] with [19] with auxilliary moving V synchronously, also can go up stretching pulley of increase at auxilliary moving V band [8], to adjust the centre distance on two limits.
The utility model device adopts two accompanying drawings
