Description
One, technical field
The utility model relates to a kind of self-locking mechanism of casting the casting ladle transmission system that industry uses, relates in particular to a kind of cycloidal-pin wheel slowdown type casting ladle transmission self-locking mechanism.
Two, technical background
Casting ladle is a kind of device of casting industry cast iron liquid, and its major requirement is:
1. it is flexible, light to vert;
2. steadily there is not " kowtowing " phenomenon;
3. reverse self-locking mechanism is arranged.
At present, what states such as domestic more than 20,000 casting producers and external U.S., day, method adopted all is worm-drive self-locking casting ladle basically, i.e. second-stage worm gear transmission or worm gear add bevel gear steering mechanism.Worm gear has bigger gearratio, also has latching characteristics, and this is that present casting ladle is used the more main cause of worm gear transmission ratio.When cast, a side of worm-gear toothing is subjected to the positive moment effect; When the synthetic center of gravity of the casting ladle that verts has just surpassed vertical zero point, become the negative moment effect that is subjected to, moment is real so changes to another side from a side of worm-gear toothing, casting ladle can produce " kowtowing " phenomenon, because of the casting ladle Sheng be iron liquid, make the people feel danger close.And the perpendicularity of worm gear, worm screw, intersect the difficult control of property, the accuracy of manufacture of worm and gear is also difficult to be grasped, tight dress does not advance, pine the gap big, " kowtowing " more goes through evil.After the wearing and tearing, also produce same problem.
In addition, worm-drive efficient is relevant with helical angle and angle of friction, and self-locking worm gear efficient all is lower than 40%.Even under same light casting ladle design premises, rotate also very effort in the use.
For manual operations cast iron liquid, it is very important that efficient seems, (〉=5t ~ 10t), the worm and gear transmission is firmly big for especially big-and-middle-sized casting ladle, have to adopt motor-driven, the cable of pulling in the iron liquid casting environment brings work inconvenience and unsafe problem again thereupon.
Three, technology contents
Technical problem: the utility model provides a kind of cycloidal-pin wheel slowdown type casting ladle transmission self-locking mechanism with self-lock ability.
Technical scheme: the utility model relates to a kind of casting industry apparatus for pouring cycloidal-pin wheel slowdown type casting ladle transmission self-locking mechanism, comprise: cover, be provided with driven coupling band and active coupling band in the cover, in the active coupling band, be provided with self-locking block and self-locking block at driven coupling band and initiatively between the coupling band, the width of self-locking block is provided with flexible member less than the cover internal diameter at the place that matches with self-locking block that puts between self-locking block and driven coupling band.
Technique effect: 1. the utility model utilizes the self-locking action of self-locking block, a kind of casting industry apparatus for pouring cycloidal-pin wheel slowdown type casting ladle power train self-locking mechanism has been proposed, comprise: cover, be provided with driven coupling band and active coupling band in the cover, in the active coupling band, be provided with self-locking block and self-locking block at driven coupling band and initiatively between the coupling band, the width of self-locking block is less than the technical measures of the internal diameter at the place that matches with self-locking block that puts, when handwheel rotates (no matter just change or reverse) under manpower drives, and when driving axle and rotating together, initiatively coupling band also rotates thereupon, simultaneously, width pushed open less than the cover self-locking block one end F (just changeing) of inside diameter D-D or other end F ' (reverses) and begin rotation, because the promotion of this direction is that self-locking block is promoted towards the gap direction between self-locking block and the cover, so this rotation is also without hindrance, the cycloidal planetary gear speed reducer power shaft that driven connecting shaft cover drives left side connection under self-locking promotes rotates together, realize verting or resetting of casting ladle, wrap in when watering that a certain position stops in the process of verting, and on the handwheel during no driving moment, casting ladle or casting ladle reach wherein, and molten iron can produce moment (promptly attempting to get back to the upright position or continue to tilt forward), driven coupling band is desired to rotate thereupon, because this rotary action moment is that self-locking block is promoted towards gapless direction between self-locking block and the cover, cover can not realize above-mentioned rotation to the inhibition of self-locking block, thereby reaches the purpose of check self-locking.And so long as left driven connecting shaft is with rotation trend (casting ladle and unartificial generation moment), no matter rotation direction how, can both realize the check self-locking, 2. between self-locking block and driven coupling band, be provided with flexible member (as spring etc.), the self-locking block and the cover of initial position are offseted, when self-locking state, self-locking block is produced pressuring action, strengthened self-lock ability of the present utility model, so these technical measures have further improved self-locking reliability of the present utility model.3. in cover, be provided with the axial limiting flange, the technical measures of this axial limiting flange between driven coupling band and active coupling band, the end face friction of having avoided may occurring in mechanism's running between the master and slave coupling band contacts, thereby has further improved the reliability of the utility model self-locking.
