Abstract
The utility model relates a machine tool accessory, in particular to a transmission device for work piece conveying on the production line. In the conical gear longitudinal single-spring friction transmission device, a transmission shaft is sleeved with a reducing friction pair; the small-radius part of the reducing friction pair is subsequently sleeved with a conical gear pair, a friction pair, a spring and a locking nut; the end of a roller shaft is fixedly provided with a conical gear pair which is meshed with the conical gear pair on the reducing friction pair. The double-sprocket single-spring friction transmission device has novel structure, solves the problems of the service life and the adjustment of the prior release raceway friction pair, has simple and reasonable structure, adjusts the friction pair on the single roller shaft, thereby determining the diameter of the roller on demand without the restriction of the friction pair; the friction pair and the conical gear pair are made of high-strength and high-wear resistance engineering plastics, and have very long service life; and the transmission of the meshed conical gear pair is stable, thereby ensuring the conveying and stopping of work piece.
Description
One, technical field:
The utility model relates to machine tool accessories, especially for the driving device of manufacturing line workpiece conveying.
Two, background technology:
At present, the manufacturing line collection is put the conveying of formula raceway, and its method that realizes the collection playing function generally has two kinds.A kind of is edge oil-containing powder metallurgy lining in roller, free-running fit between lining and the axle, and when workpiece was blocked by stock stop, roller did not change and has only axle idle running, realizes collecting playing function; When stock stop was decontroled, axle drove the roller rotation by lining, realizes the workpiece conveying function.Another kind is to add spring and friction pair at the roller end face, adjusts spring pressure, and when workpiece was blocked by stock stop, roller did not change and has only axle idle running, realizes the collection playing function; When stock stop was decontroled, axle drove the roller rotation by spring and friction pair, realizes the workpiece conveying function.When first method is put when collection, easily cause oil-containing powder metallurgy lining localized wear, when serious roller can't be rotated, and make raceway lose function.It is very big that second method is needed by friction pair structure influence roller diameter, the equipment cost height, and big some occasion of volume can't be used because of the space reason, need adjust each last two roller friction force in addition respectively, has increased a large amount of adjusting work amounts.
Three, summary of the invention:
The purpose of this utility model is to address the above problem, and provides a kind of conical gear vertical single spring friction gear, and simple in structure, volume is little, easy to adjust and long service life.
The technical scheme that the utility model is adopted for achieving the above object is: the vertical single spring friction gear of conical gear, be set with the reducing friction pair on the transmission shaft, reducing friction pair path part is set with conical gear pair, friction pair, spring and jam nut successively, and conical gear pair and the secondary engagement of the conical gear on the reducing friction pair fixedly are equipped with in the roller shaft termination.
Described reducing friction pair is connected with transmission shaft by gland.
Described friction pair is captiveed joint by key with the reducing friction pair.
Described roller shaft is captiveed joint by key and conical gear are secondary.
The structure of described reducing friction pair is the reducing body that has keyway and end thread.
The utility model novel structure, solve collection and put raceway friction pair life-span and adjustment problem, simple and reasonable, realize adjusting friction pair on the single roller shaft, determine the roller diameter size as required, and not limited by friction pair, friction pair, the secondary high-strength, high-anti-friction engineering plastics that adopt of conical gear are made, have high service life, and intermeshing conical gear auxiliary driving is stable, guarantees the conveying of workpiece and stop.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
Five, the specific embodiment:
As Fig. 1, the vertical single spring friction gear of conical gear shown in 2, workpiece 1 is on roller shaft 2, roller shaft 2 links to each other with wallboard by bearing, the reducing friction pair 5 that has keyway and end thread links to each other with transmission shaft 12 by connecting gland 4, conical gear pair 6, friction pair 7, spring 9, jam nut 11 is sleeved on the path part of reducing friction pair 5 successively, friction pair 7 is fixedly set on the reducing friction pair by link button 8, conical gear pair 3 is fixedly linked by link button 10 and roller shaft 2, conical gear secondary 3 and secondary 6 engagements of conical gear, transmission shaft 12 links to each other with wallboard by bearing seat.
During work, adjust jam nut, friction force between friction pair 7 and the conical gear pair 6 is set to greater than the workpiece dynamic friction and less than the workpiece static friction, 12 rotations of power driven transmission shaft, drive 5 rotations of reducing friction pair by connecting gland 4, reducing friction pair 5 drives suit conical gear pair 6, friction pair 7, spring 9, jam nut 11 rotations thereon, conical gear pair 3 is rotated under the driving of conical gear pair 6, drive the roller shaft 2 captive joint with it and rotate, the roller shaft 2 rotating bands part 1 of starting building advances; If workpiece 1 is blocked, roller shaft 2 does not rotate, and transmission shaft 12 drives reducing friction pair 5, friction pair 7, spring 9, jam nut 11 empty rotations by connecting gland 4.Adjust jam nut 11, can adjust reducing friction pair 5, friction pair 7 and the secondary 6 friction force sizes of conical gear, guarantee that workpiece 1 is blocked, roller shaft 2 does not rotate, and workpiece 1 is decontroled, roller shaft 2 rotations.
