Abstract

The utility model relates to a fatigue strength tester for a brake, which comprises a loading mechanism connected with a sample rotation part, an equipment tailstock which is connected with a sample fixed part and provided with a force transducer and a torque arm, a tension mechanism connected with a sample by a brake oil pipe, and a control cabinet which controls the loading mechanism to run, controls the tension mechanism to produce cycle brake pipe pressure so as to conduct cycle brake over the sample and displays a signal of the force transducer. The loading mechanism comprises a motor, a reducer, a transmission shaft and an intermediate support and the sample rotation part is arranged on the intermediate support which is connected with the motor by the transmission shaft and the reducer in a driving manner. The fatigue strength tester adopts a continuously-rotating torque loading mechanism, which not only renders the tester to have simple and reliable structure, and simple and clear test control, but also overcomes the defects of the existing technical control which is fussy cycle and unpractical. The fatigue strength tester adopts a gear transmission manner to transmit power, which significantly improves the transmission efficiency, thereby lowering the energy consumption greatly.

Description

Detent Stromeyer test device
Technical field
The utility model relates to a kind of detent Stromeyer test device, is mainly used in the test field of detent fatigue strength.
Background technology
At present when the detent Stromeyer test is carried out the moment of torsion loading, all laboratories and enterprise all adopt the reciprocating type moment of torsion load maintainer described in the automobile industry standard QC/T316-1999 " running detent fatigue strength bench test method ", and adopt hydraulic jack as actuator mostly.This reciprocating type load maintainer not only causes testing control cycle and becomes loaded down with trivial details because involve the reason that needs return, the situation that turns round continuously when also not meeting the detent actual motion; And the hydraulicefficiency that adopts is low, and energy consumption is very big.
Summary of the invention
In order to overcome that present detent fatigue test board energy consumption is big, the cycle is loaded down with trivial details and not conform to actual deficiency, the utility model provide a kind of simple in structure, control is convenient, reliable, detent fatigue experimental device that energy consumption is low.
The technical scheme that the utility model adopted: comprise a load maintainer that connects the sample rotating part; Comprise an equipment tailstock that connects the sample fixed part, the equipment tailstock is equipped with the force transducer and the arm of force; Comprise a pressing mechanism that is connected with sample by brake pipe; Comprise that also a control loaded mechanical operation, control pressing mechanism produce the switch board of cycle brake-pipe pressure to the braking of sample implementation cycle, demonstration force sensor signals, described load maintainer comprises motor, speed reduction unit, transmission shaft and intermediate support, and the rotating part of sample is loaded on intermediate support and is connected with drive of motor through intermediate support, transmission shaft, speed reduction unit.
Parts in the described load maintainer are rigidly connected.Main gearing---speed reduction unit in the described load maintainer, the kind of drive of employing are gear transmission mode.Described load maintainer is equipped with protective shield outward.
The parts of moment of torsion load maintainer of the present utility model (motor, speed reduction unit, transmission shaft, intermediate support) adopt and directly are rigidly connected, and are simple in structure, the power transmission efficiency height.The moment of torsion load maintainer turns round continuously according to standard-required speed, the detent actual operating state of fitting more, and need not extra control after the running, do not need return, so the control of pressing mechanism the time is only carried out in test period control; Compare former detent Stromeyer test device, not only need to control the action of the action of reciprocal moment of torsion load maintainer, return and pressing mechanism, also will be with both organic connections situation together, present test control cycle is obviously simple and clear, has overcome the loaded down with trivial details shortcoming of present detent fatigue test board control cycle.
Power delivery mode of the present utility model adopts gear transmission mode, has overcome the big shortcoming of hydraulic transmission mode energy consumption in the prior art, and transmission efficiency improves greatly, thereby can cut down the consumption of energy significantly.For the torture test project of this (when a general test needs 200 testing tables) consuming time big energy-consuming, this point is particularly important.
The beneficial effects of the utility model are to cut down the consumption of energy, and this test unit is simple in structure, control is convenient, reliable, it is actual to fit more.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
1. switch boards, 2. equipment tailstocks, 3. force transducers, 4. arm of forces, 5. samples, 6. intermediate supports, 7. transmission shafts, 8. protective shields, 9. speed reduction units, 10. motors, 11. pressing mechanisms among the figure
Embodiment
In the accompanying drawing, motor of the present utility model (10) directly links to each other with speed reduction unit (9), is connected with intermediate support (6) by transmission shaft (7) again.The rotating part of sample (5) is connected with intermediate support (6), and its fixed part directly is connected with equipment tailstock (2), and the force transducer (3) and the arm of force (4) also have been installed on the equipment tailstock.Pressing mechanism (11) links to each other with sample (5) by brake pipe.The control of motor (10) and all controlled cabinet of pressing mechanism (11) (1), the signal of force transducer also are introduced into switch board (1) and show and control.
Actual when carrying out the detent Stromeyer test, switch board (1) control motor (10) starts, the rotating part that drives speed reduction unit (9), transmission shaft (7), intermediate support (6) and sample (5) rotates continuously, switch board (1) control pressing mechanism (11) produces the cycle brake-pipe pressure simultaneously, sample (5) implementation cycle is braked, the signal that the last force transducer of equipment tailstock (2) records passes to switch board (1), by the torque arithmetic formula: the arm of force * power=moment of torsion, the force signal of being surveyed is converted to torque value, thereby obtains torque value.If the non-compliant regulation of torque value that obtains can obtain suitable value by the adjusting of pressing mechanism (11).Because test torque is bigger, therefore protective shield (8) has been installed also outside load maintainer, prevent to cause when unusual security incident.
