Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

Известен стенд дл испытани муфт, содержащий многошпиндельный блок, на каждом шпинделе которого установлена испытываема муфта, имеюща ведомую полумуфту закрепленную на валу щпиндел и ведущую полумуфту, соединенную со втулкой щпиндел , и зубчатую передачу между втулкой щпиндел и приводным валом, а также нагружающее устройство 1.A stand for testing couplings is known, comprising a multi-spindle unit, on each spindle of which a test sleeve is installed, having a driven coupling half fixed on the shaft of the pinch spindle and a driving coupling half connected to the sleeve of the spindle, and a gear transmission between the sleeve of the pinch and the drive shaft, as well as a loading device 1.

Цель изобретени - расщирение технологических возможностей стенда.The purpose of the invention is to expand the technological capabilities of the stand.

Поставленна цель достигаетс за счет того, что нагружающее устройство . выполнено в виде нескольких фракционных муфт, установленных по одной на валу каждого шпиндел , соединенном с ведомыми дисками , а ее ведущими дисками и приводным валомвстроена дополнительна зубчата передача, при этом передаточные отношени зубчатых передач различны.The goal is achieved due to the fact that the loading device. made in the form of several fractional clutches mounted one on the shaft of each spindle connected to the driven disks, and an additional gear transmission is built into its drive disks and drive shaft, while the gear ratios of the gears are different.

5 коаксиально расположенные вал 7 и втулку 8.5 coaxially located shaft 7 and sleeve 8.

На каждом валу 7 установлено нагружающее устройство, выполненное в виде фрикционной муфты, несущей на ведущих дисках 9 зубчатое колесо 10, а ее ведомыеOn each shaft 7 a loading device is installed, made in the form of a friction clutch, which carries a gear 10 on the driving disks 9, and its gears

10 диски соединены с валом 7. На втулке 8 установлено зубчатое колесо 11, а на приводном валу 12 зубчатое колесо 13. Зубчатые колеса 11 щпинделей 2-4 соответственно наход тс в зацеплении с зубчатыми колесами 14, расположенными на приводном 10, the disks are connected to the shaft 7. A gear wheel 11 is mounted on the hub 8, and a gear wheel 13 is mounted on the drive shaft 12. The gear wheels 11 of the pins 2-4 are respectively engaged with the gear wheels 14 located on the drive wheels.

Передаточные отнощени зубчатых передач различно .15 to the shaft 12 connected by a belt drive 15 with the drive 16. The wheels 10 and 13 form an additional gear train. Gear ratios of gears are different.

Claims

20 To ensure a rational arrangement of the working shafts, the gears 10 and 11 mounted on the working shpindle 4 are additionally engaged with the gears 17 and 18 placed on the intermediate shaft 19. The gears 17 and 18 interact with the gears 10 and 11, located on the spindle x 5 and 6. On the shaft 7 of the spindle there is a lug installed, and the coupling half 20 of the test coupling 21, and on the sleeve 8 - driven by the coupling half 22 of the test coupling. The shafts 7 are fitted with disks 23 of the device 24 for detecting the slippage of the disks 25 of the tested couplings 21. On the shaft 12 there is a disk 26 of this device. The disks 23 have slots, the number of which is equal to the number of teeth of the wheels 10, and the number of slots in the disk 26 is equal to the number of teeth of the wheels 13. The device is electrically connected with the sensors 27, feed, their signals about the number of the passed slots of the disks 23 and 26. to the squares 28 of the shafts 7 with a device for creating a calibration torque on them and a locking mechanism for locking the drive shaft (not shown). With the aid of the aforementioned device and mechanism, as well as the nuts 29 of the coupling 9, the load device is adjusted for the greatest moment transmitted by the test couplings. The stand works as follows. The clutches of the load device are adjusted to the maximum steepest torque of the tested clutches. When the drive is turned on, 16 through the belt drive 15, the movement connects the drive shaft 1 (2 with the gears 14 and 13 and then through the gears 10 and 11 to the shaft 7 and the hub 8 of the spindles 2-4. Then through the gears 17 and 18, located on the intermediate shaft 19, and gears 10 and 11 connected to spindles 5 and 6, the movement is transmitted last. At the same time, shafts 7, spindles will rotate at a speed proportional to the ratio of the number of teeth of wheels 10 and 13, and sleeves 8c speed proportional to the ratio of the number of teeth of the wheels 11 and 1 4. The drive and driven coupling halves of the tested couplings will be built at the same speed. The difference in the speed of the coupling creates the relative slip of the disks 25 of the tested couplings, which is necessary for the burn-in. the clutch is checked for the maximum torsional moment. If the disks 25 slip, which is fixed by the device 24, then it should be considered that the disks are not sufficiently lapped. In this case, the pressing force is reduced to the initial one and the burn-in process is continued. If the clutch is tested normally, then with the working force of the pressing the discs slip, and the discs of the 6 clutches of the loading device slip. In the absence of slippage of the disk 25 of the test sleeve, each sensor 27 outputs the same number of pulses and the counter of the device 24 indicates the absence of slippage. The slippage of the discs 25 is recorded by a counter. The proposed stand allows for alternate testing of the couplings on. the transmitted stellar moment is to simultaneously run in all the couplings mounted on the stand. Claims for testing clutches containing a multi-spindle unit, on each spindle of which a test coupling is installed, leading to the coupling half which is connected to the spindle hub and driven to its shaft, a gear transmission placed between the spindle hub and the drive shaft, as well as a loading device , characterized in that, in order to expand technological capabilities, the loading device is made in the form of friction clutches mounted one on the shaft of each spindle connected to the driven disks, and ezhdu its leading disc and the drive shaft is integrated gearing, the gear ratios of gears of different sources of information received into account in the examination 1.
