Abstract
The utility model relates to a device for a high speed falling body realizing uniform speed descent. A speed regulating motor drives a worm speed reducer through a belt pulley pair; the worm speed reducer can drive a speed increasing gear pair to drive a uniform speed shaft to rotate; the uniform speed shaft is connected with an overrunning clutch; a tacho-generator contacts the uniform speed shaft; a loaded object is hung on a wire rope hook, and is wound on a hoist cylinder via a pulley wheel; one end of the cylinder is provided with a brake; a hoist shaft contacts the overrunning clutch; another tacho-generator contacts the hoist shaft. When the uniform speed shaft reaches a preset speed, the overrunning clutch can slip, the brake is loosened, and the loaded object can freely fall down; when the speed of the hoist exceeds the rotating speed of the uniform speed shaft, the overrunning clutch is closed, the rotating speed of the hoist can be equal to the speed of the uniform speed shaft, and the object falls at a uniform speed.
Description
This device is used for the Machinery Control System that the requirement objects at high speed at the uniform velocity descends, and is specially adapted to simulation test objects such as Aeronautics and Astronautics, throwing umbrella.
At present the structure of external this device is found as yet, does not also see relevant literal report in the document newpapers and periodicals as yet, and doing the machine control unit that objects at high speed at the uniform velocity descends at home also is first, requires the spy to do following design in order to satisfy user's special type.
The purpose of this utility model is that a kind of high speed falling objects of design is realized at the uniform velocity lowering means.
The technical scheme of this utility model is: utilize the gravity of object to make object " freedom " whereabouts one segment distance, after reaching predetermined decline rate, decline rate is subjected to the restriction of another uniform rotation machinery, at the uniform velocity descend thereupon, the machinery of uniform rotation selects for use worm gear pairs to come transmission, its objective is that the reverse self-locking performance that utilizes worm drive to reach after certain reduction gear ratio limits the falling bodies speedup, reach the purpose that important parameter is obtained in user's experiment.
Details are as follows in conjunction with the accompanying drawings for the structure of this utility model: stepless speed regulation direct current generator (1) is paid (2) by belt pulley and is driven worm reducer (3), worm reducer (3) is paid (4) and is connected with increase gear, increase gear pay (4) with at the uniform velocity the axle (5) one ends connect, at the uniform velocity axle (5) other end connects with overrunning clutch (8), at the uniform velocity axle (5) is supported by two bearing seats (7), tachogenerator (6) with at the uniform velocity the axle (5) contact, load object (12) ties up to wire rope and colludes, by pulley (13) on elevator machine barrel (11), there is detent (10) elevator machine barrel (11) the inner, elevator machine barrel axle inner end connects with overrunning clutch (8), elevator machine barrel axle is by two bearing seats (7) supporting, and tachogenerator (9) is coupling with the elevator machine barrel and touches.When using this device, the load object that wire rope is hung oneself, by pulley (13), elevator machine barrel (11), rise to certain height, with detent (10) the load object is hung in the sky, make stepless speed regulation direct current generator (1) turn to the direction that descends into the load object, direct current generator (10) is paid (2) by belt pulley, worm reducer (3), increase gear is paid (4) makes at the uniform velocity axle (5) reach desired speed, and at this moment overrunning clutch (8) skids, automatically release brake (10) load object promptly " freedom " fall, when the axle rotating speed of elevator machine barrel (11) is increased to when surpassing at the uniform velocity axle (5) rotating speed, overrunning clutch (8) closes automatically, and the axle rotating speed of elevator machine barrel (11) can not surpass at the uniform velocity axle (5), and the load object can only at the uniform velocity fall thereupon.
This utility model has the following advantages:
1, simple in structure, be easy to make, small investment.
2, stable and reliable for performance
3, decline rate wide ranges at the uniform velocity can surpass 10 meter per seconds at a high speed
4, at the uniform velocity the section velocity-stabilization
5, can be widely used in and require in the various plant equipment that object at the uniform velocity descends
