(4) description of drawings
Fig. 1 is the structural representation of double-speed and double-torque transmitting device.
(5) embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, a kind of double-speed and double-torque transmitting device, comprise the motor output shaft 2 that is connected with drive motor 1, described motor output shaft 2 is connected with little clutch shaft 4 by first coupling 3, first magnetic clutch 5 is installed on the described little clutch shaft 4, the armature 6 of described first magnetic clutch is fixedlyed connected with little clutch shaft 4, the armature 7 of described first magnetic clutch is connected with little load active synchronization belt wheel 8, the connecting sleeve 9 of first magnetic clutch connects with little clutch shaft 4 by bearing, the armature 7 of first magnetic clutch can move axially along little clutch shaft under the electromagnetic force effect, little clutch shaft 4 is connected with input shaft of speed reducer 11 by second coupling 10, the output shaft 13 of described retarder 12 is connected with heavy load active synchronization belt wheel 14, described little load active synchronization belt wheel 8 is with 15 to be connected with the driven synchronous pulley 16 of little load by first synchronously, described heavy load active synchronization belt wheel 14 is with 17 to be connected with the driven synchronous pulley 18 of heavy load by second synchronously, the driven synchronous pulley 16 of described little load is fixedly connected on transmission shaft 19, second magnetic clutch 20 is installed on the described transmission shaft 19, the armature 21 of described second magnetic clutch is fixedlyed connected with transmission shaft 19, the armature 22 of described second magnetic clutch is fixedlyed connected with the driven synchronous pulley 18 of heavy load, the connecting sleeve 23 of second magnetic clutch connects with transmission shaft 19 by bearing, the armature 22 of second magnetic clutch can move axially along transmission shaft under the electromagnetic force effect, and transmission shaft 19 is connected with the connection interface of device to be measured.
Described retarder 7 is a plane table thermoconductivity meter.Described drive motor 1 is an AC servo motor.
Use the reason of two magnetic clutchs to be: working method 1 (not using retarder): the clutch pack user mode is: second magnetic clutch, 20 dead electricity (inefficacy), first magnetic clutch 5 powers up (effectively), and motor (not using retarder) → coupling 3 → little clutch shaft 4 → the first magnetic clutchs 5 → little load active synchronization belt wheel → first be the connection interface of the driven synchronous pulley → transmission shaft of band → little load → device to be measured synchronously.Working method 2 (use retarder): the clutch pack state is: second magnetic clutch 20 powers up (effectively), first magnetic clutch, 5 dead electricity (inefficacy).Motor → coupling 3 → little clutch shaft 4 → coupling 10 → retarder → heavy load active synchronization belt wheel → second be the connection interface of the driven synchronous pulley of band → heavy load → second magnetic clutch, 20 → transmission shaft → device to be measured synchronously.
This drive motor is an AC servo motor, can be drive motor, also can be load; Can realize the double-direction twist moment transmission.
Do not use retarder, being added on the connection interface of device to be measured is little moment, high rotating speed.Use retarder, being added on the connection interface of device to be measured is big moment, the slow-speed of revolution.The moment scope that requires when operating condition of test be 1Nm to 200Nm, speed range is 1rpm during to 3500rpm, satisfies moment so on a large scale as not using retarder, must use tens kilowatts of motor.Use retarder, can use the motor of smaller power.But because retarder is gap when suppressing clockwise and anticlockwise, disposed the device of the several Nm moments of preload on the structure,, can't satisfy the loading requirement of 1Nm according to test.So our scheme is to adopt clutch pack to switch retarder, to satisfy the wide range requirement that loads and drive rotating speed and moment.
