Abstract
The utility model discloses a multifunctional idler detector comprising a driving wheel and two driven wheels, wherein an alternating load device is arranged on a belt so as to simulate the working condition of a timing belt wheel train of an automobile engine; a fixed plate for installing and clamping a product to be detected is arranged on the belt between the two driven wheels; a temperature sensor is arranged on a central spindle on the fixed plate; a vibration sensor is arranged at the side edge of the product to be detected; the fixed plate is arranged on a sliding guide rail which is tightly propped by a transition plate; the top end of the transition plate is provided with a pressure sensor; the transition plate is pushed to conduct displacement through a loading screw; and measuring load born by the product to be detected is changed by adjusting the loading screw so as to further obtain valid data. The multifunctional idler detector can scientifically and effectively detect vibration values of a tensioning wheel and an idler in a simulated working condition, and correctly identify abnormal noise. The multifunctional idler detector also provides correct data for deep understanding and research on changes of the vibration and noise of the tensioning wheel and the idler caused by different working environment conditions such as temperature rising of the tensioning wheel and the idler, magnitude of load, load bearing area size and the like.
Description
Technical field
The utility model relates to the device for detecting performance of a kind of motor car engine stretching pulley, idle pulley.
Background technology
Along with the fast development of automobile industry and improving constantly of living standards of the people, car progressively becomes the walking-replacing tool of common hundred property families.But increase along with car population, the claim issue after sale of some part is also outstanding day by day, especially for want of corresponding authoritative standard and effective detection method on to the judge of claiming damages part after sale, usually can only adopt simple methods such as range estimation, so the incorrect rate of evaluation result is also just high.
The abnormal voice problem of motor car engine stretching pulley, idle pulley just can prove absolutely this problem.Owing to be subjected to the restriction of motor car engine stretching pulley, idle pulley product structure feature and applying working condition, stretching pulley, idle pulley vibration values and the abnormal sound under the simulated engine operating condition can't detect in the present domestic institute generally special bearing vialog of use; So, the way whether stretching pulley, idle pulley exist the problem of abnormal voice can only adopt people's ear to listen is discerned, there are not a kind of science, effective detection means to be detected, more there is not defining standard.This problem is perplexing the manufacturer of main engine plants and stretching pulley, idle pulley all the time for a long time.Therefore, be badly in need of a kind of special detector that can under simulation stretching pulley, idle pulley duty, detect stretching pulley, idle pulley performance of development, fill up the blank of no special inspecting equipment, no industry standard.
The utility model content
The purpose of this utility model provides a kind of multi-functional idle pulley detector, and the play that has solved the bearing of interference fit between bearing insert and the bearing is difficult to control, has increased machining period, the problem that cost is high.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of multi-functional idle pulley detector comprises that a driving wheel and driving wheel drive two engaged wheels with belt, is provided with the alternate load device of being made up of eccentric wheel, contact roller and rail plate on belt, comes the operating mode of simulated automotive engine timing belt train; Rotate the to-and-fro movement of promotion rail plate by eccentric wheel, the contact roller of installing on the rail plate compresses belt;
On the belt between two engaged wheels, be provided with the fixed head of the product to be measured that is installed, mounting temperature sensor on the mandrel on the fixed head, side at product to be measured is provided with vibration transducer, fixed head is installed on the rail plate, described vibration transducer is fixed on the rail plate, described rail plate is held out against by rebound, the top of rebound is provided with pressure transducer, rebound promotes displacement by load screw, the measurement load that test product is born by the adjusting load screw changes, and then obtains valid data.
Can science and detect stretching pulley, the vibration values of idle pulley under the analog operation state effectively, and can correctly identify unusual sound.Have a extensive future at international and domestic stretching pulley, idle pulley production field, have higher using value.Also be profound understand and different operating environmental baselines such as the temperature rise of research stretching pulley, idle pulley, magnitude of load, bearing area size to the vibration of stretching pulley, idle pulley and the situation of change of noise, correct data are provided.
The research and development of this special detector success, not only can standard to the correct judgement of stretching pulley, idle pulley abnormal voice, reduce False Rate, prolong the serviceable life of stretching pulley, idle pulley, avoid the waste of resource; While also provides reliable foundation for the continuous Continual Improvement of stretching pulley, idle pulley quality, and the quality level that promotes domestic stretching pulley, idle pulley series of products is had positive help meaning.Meanwhile, also be the technical data of the formulation accumulation science of industry standard from now on.
